This invention relates to garments for use in sports training, physiotherapy or in other fields and applications, to train the wearer to adopt a good posture and encourage healthy movements of the limbs and body. Injuries resulting from mechanically overstressing muscles, joints and tendons, as well as more chronic musculoskeletal disorders, may thereby be mitigated or avoided. The invention also relates to similar sports training or physiotherapy garments and their components, used to tone and exercise the muscles, and promote muscle, bone and/or joint strength.
A known form of garment which aims to optimise human posture and motion consists of a close-fitting, full or partial, body suit of stretchable fabric, reinforced in strategic areas by bands or panels of elastic material. These bands or panels are positioned and aligned relative to associated muscles and joints, so as to resist movements at the joint away from an optimum rest position. This encourages the user to learn to adopt that position as their normal resting position, as well as acting to strengthen and tone the muscles, Examples of such garments are shown in EP2813154A1 and U.S. Pat. No. 9,895,569B2, While such elastic reinforcing bands or panels may be effective in encouraging a good resting posture, their known implementations are less effective in encouraging healthy body movements, or particular body movements which are more efficient for performing associated activities; whether in sport, daily life, or in other contexts, such as at work or in the fields of occupational health, physiotherapy and orthopaedics. The known elastic reinforcing bands and panels are arranged to resist displacement of the associated joint away from a particular resting position, with greater displacements tending to produce higher resistance forces to the movement. However these known arrangements do not provide adequate guidance of the direction of rotational motion at the joints (or stabilization of a joint or joints) at particular relative rotational positions. To strengthen the muscles, the elastic resistance becomes substantial at high extensions. Further movement of the joint concerned may therefore be inhibited. These arrangements of elastic reinforcing bands therefore do not provide adequate dynamic guidance for the mechanism of the muscles, bones and joints, necessary to train healthy movement and/or more efficient motion in carrying out particular physical tasks.
Another known form of garment is fitted with weights (masses) which are subject to gravitational force and which also provide accelerational/decelerational forces, to increase the load on the wearer's muscles, joints and bones, or on particular joints, muscles or muscle groups in use. The weights may be removable or replaceable with weights of differing mass, e.g. so as to vary the imposed loads to suit the physique or fitness level of the user, and/or to work on particular muscles or muscle groups etc. The removable weights are typically housed in openable/securely recloseable pockets permanently attached to the garment. Or they may be in the form of packets or packages removably fastenable to the garment by hook-and-loop type fastening patches, poppers, buttons or the like. Yet alternatively, the weights may be permanently secured to or within the garment.
To make the garment comfortable to wear and to avoid interference and distraction during physical activity, measures may be taken to minimise relative movement between the weights and the part of the use's body which they overlie. For example, the garment may be close-fitting and formed from a suitable elastic material such as Lycra (RTM) or Spandex (RIM). Thus the garment may be sized to stretch when worn, to at least lightly compress parts of the wearer's body that it covers. The garment or the material that it is made from may include substantially inextensible material or threads or fibres, which connect to or interconnect the weight pockets or weight attachment locations, so as to distribute the corresponding forces in the stretchable fabric of the garment, and/or to prevent the weights from sagging under gravity or moving under dynamic loads. For example, the inextensible components may form a harness-like structure by which the weights are suspended from suitable parts of the wearer's body; for example forming a belt-like structure about the wearer's waist, and/or a halter-like structure about the wearer's neck and/or shoulders. The substantially inextensible harness-like structure about the wearer's torso may be connected to one or more extensions running the length of one or more of the wearer's limbs, to provide centripetal acceleration forces during curved motion of any weights attached to that limb. Axial shifting of the weights and gravitational and centripetal loading of the limb joints are thereby resisted. Shifting of the weights circumferentially about, or radially away from, the wearer's limbs or torso, may be resisted by the pressure of the stretched garment fabric against the wearer's body.
The weights themselves are placed in locations where they will not obstruct movement of the wearer, e.g. away from the wearer's joints. For example they may be located over the muscles and/or connective tissues that they are intended to load. Alternatively, they may reside on a segment of the body which requires muscles for its movement which are local but not directly adjacent, such as the bicep/tricep contracting in order to move the forearm. The weights may be formed from suitable dense Plowable materials such as water or sand in a flexible container or pouch. This makes the weights comfortable to wear, as they mould themselves to the wearer's body. However as the weight material is mobile, it can move about in its container during exercise, possibly distracting the garment wearer or throwing the intended movement out of balance.
Alternatively, the weights may be formed from suitable dense solid materials, such as metal. This kind of weight is less comfortable to wear, and might even cause injury to the wearer during vigorous exercise. To address this problem, the solid weights may be subdivided into small separate parts, each inserted or sewn into its own articulated textile compartment, often together with a wrapper or padding, to form a flexible weight package or assembly. These measures however decrease the overall density and hence increase the bulk of the weights, sometimes to the point where they can interfere with movement of the wearer and also possibly spoiling the aesthetic appeal of the garment. Alternatively, the weights may be formed from suitable flexible solid materials, such as silicone elastomers and/or gels. Such weights are in general comfortable to wear but are however of quite low density. This again can lead to undesirably bulky weights.
US6047405, U.S. Pat. No. 5,555,562, GB2462477A, WO2017/218765A1, U.S. Pat. No. 5,144,694, US2002/0010058A1, US2017/0304670A1, U55553322 and US8156572B2 provide an indication of the technological background in this area. WO2018/075757 discloses articles of apparel, including an integrated fabric system comprising strategically-placed weighting and/or elastic resistance elements formed from an elastomer such as medical grade silicone, rubber and/or one or more gel substances. The resistance elements may be impregnated with a relatively heavy (dense) material, which may be in the form of particles or powdered elements. It appears that the heavy material must be in atomic, molecular or finely divided particulate form, because it must be impregnated (together with the uncured elastomer matrix-forming material) into the base textile fabric from which the apparel is formed. US807908 discloses an improved harness constructed of straps of elastic webbing, adjustable to fit different human body sizes. The harness is presented as an improvement of the general class of exercising devices which exert strain or resistance on the human body in opposition to the movements of the various body members, Though it is mentioned that no special exercise regime is needed other than normal daily activities, and that the opposition to movement may be slight, the objective is still to develop the wearer's muscles by resistance training, rather than simply to provide enhanced feedback of body part movement and positioning, U.S. Pat. No. 5,606,745A also concerns a resistance exercise suit, i.e. again to provide muscle development, rather than movement feedback. The resistance members are provided in elongate pockets in the suit, and appear to resist bending rather than resisting elongation.
The present invention aims to address at east some of the problems mentioned above.
Accordingly, in a first independent aspect, the present invention provides a posture and movement training garment (hereafter “posture garment”), comprising at least one elastic element arranged to be stretched upon movement of the wearer's trunk and/or at least one of the wearer's limbs away from a predetermined rest or neutral position, thereby to provide the wearer with gentle elastic recoil sufficient to provide the wearer with additional kinaesthetic and/or touch feedback resulting from the movement, substantially without inhibiting the movement. Such feedback-generating elastic elements provide tension whose recoil reacts on the limbs and/or trunk in a direction tending to pull them towards a default (for example symmetrical) posture or stance, after any movement of the body and/or one or more of the limbs away from that default position. The tension or reactive recoil of the elastic element is perceived by the body/brain so as to provide a powerful directional and positional feedback regarding the corresponding movement. The wearer's learned body representation (learned spatial map of the parts of the body, their current positions and possible movements, derived from messages from the muscles, ligaments and joints) is thereby enhanced. The user may then more easily activate their muscles to correct their body's position or posture, and/or to follow a movement pattern which is closer to the optimum for a particular physical activity.
For example, there may be minimal tension and elastic recoil provided by the elastic element when the wearer is in a healthy upright posture. As the user's body moves within the posture garment, the elastic element(s) generate a recoil to direct or guide the body gently back towards the default healthy posture. The elastic element(s) allow(s) for natural movement but help to keep good body form and posture, e.g, for a healthy and balanced upright stance, and/or for particular physical activities, and or to prevent uncontrolled motion around the limbs or trunk.
The material elastic constant of the elastic elements may be less than or equal to 3600 N m, optionally less than or equal to 2400 N/m. A material elastic constant of less than or equal to 360 N·m−1 for the elastic element(s) can serve to provide most wearers of the posture garment with kinaesthetic or touch feedback while not overly inhibiting the user's natural body movements. Higher material elastic constants may be used, e.g. up to 500 N·m−1 in the case of particular individuals, or classes of individual, having a higher strength and/or stamina; e.g. the very fit and strong, or elite athletes and sportspeople.
To provide adequately perceptible kinaesthetic or touch feedback to most users (e.g. to be distinguishable from the light tension and compression provided by a stretchable base layer of the posture garment onto or into which the elastic element(s) may be applied or incorporated), the material elastic constant of the elastic element(s) may be at least 90 N·m−1 It may be higher in some cases, e.g. 150 N·m−1 or more, e.g. around 190 N·m−1 where the posture garment is to be worn together with thick or heavy (and therefore somewhat movement inhibiting) protective padding or clothing; or to be worn together with a resistive training garment, such as the weighted garments described elsewhere in this specification. The material elastic constant of the elastic elements may be 600 N/m or greater, optionally 1000 N/m or greater. Different ones of the elastic elements may have different material elastic constants and/or lengths, e.g. providing recoil adapted to the pulling power and the range of movement of the corresponding muscle/joint/bone mechanisms in the wearer. For example the different elastic elements may be made from different materials. Additionally or alternatively, the different elastic elements may have different lengths and/or widths and/or number of layer(s) of material, which again may provide recoil adapted to the pulling power and the range of movement of the corresponding muscle/joint/bone mechanism in the wearer. The stress-strain behaviour of some or all the elastic elements may be non-linear, and/or rate dependent, e.g. viscoelastic.
The presence and use of the above-described elastic elements in the posture garment does not preclude the presence and use of other elements (whether elastic or substantially inelastic) in, of or attached to the posture garment, which do serve to substantially resist, restrict or inhibit particular movements of the user's trunk and/or limbs.
The posture and movement training garment may be used encourage neuromuscular activation in under-active muscles and neuromuscular inhibition in overactive muscles by providing the required positional feedback to enhance the wearer's awareness of regions of the body where muscles are overextending and regions where muscles are underextending. The posture and training garment may provide neuromuscular activation and neuromuscular inhibition in both kinetic sequences and stationary positions through targeted elastic tension lines, which act moderately against the user from many angles even in a neutral upright and symmetrical posture setting and increase proportionately against a body segment whose posture and/or movement is to be trained, as it deviates away in any direction from the neutral setting.
The posture and training garment may provide a matrix of the elastic elements which converge at regions which have no specific anchoring points, mimicking the architecture of human fascial lines which do not end abruptly but instead link together and converge in particular regions of the body.
The neuromuscular effects of the posture and training garment may be complemented by loading the body with additional mass, with the mass providing increased resistance to muscle contraction (as well as optionally simulating added muscle mass) and the posture and training garment assisting the body in maintaining optimal and correct positioning through its elastic matrix which encourages adoption of symmetrical and neutral upright positions. The posture and training garment trains and promotes chronic/long term adaptations that relate to speed, acceleration, deceleration, vertical jump height and potentiation of the nervous system in human trials by providing elastic forces which help to correctly and efficiently position the user even during high velocity and dynamic movement patterns, who may then be loaded with added mass, having created specific adaptions to increased physical demands.
The recoil of the elastic elements may provide the wearer with enhanced guidance for relative movement of different portions of the trunk or torso, for example of the shoulder girdle, thorax, abdomen, spine, core, and pelvic girdle/sacrum, and/or of points or positions in between these, such as the sternum, mid-back, mid-point between the anterior pelvic ridge and the umbilicus.
The recoil of the elastic elements may additionally or alternatively provide the wearer with enhanced guidance of movement of the head and/or limbs relative to the trunk, and/or between different portions of the limbs. For example, enhanced guidance of relative movement of the shoulder girdle and a point along (e.g. approximately half-way along) the length of the humerus; between a point along the humerus (e.g. as above) and a point along (e.g. approximately half-way along) the forearm; between the pelvic girdle and a point along (e.g. approximately half-way along) the thigh bone; and/or between a point along the thigh bone (e.g. as above) and a point along (e.g. approximately half-way along) the shin. The additional kinaesthetic and/or touch feedback may be provided for one, two or three orthogonal planes of rotation or degrees of rotational freedom of the movement. For example, relative rotational motion of the different parts of the trunk (shoulder girdle, pelvic girdle, etc.) may be guided in the sagittal, frontal and/or transverse planes. Enhanced movement feedback and guidance for the core muscles and joints may be provided to the wearer by specific elongate elastic elements arranged in the posture garment over the wearer's abdominal muscles and posterior spine.
The elastic elements associated with the wearer's trunk may be connected to elastic elements providing enhanced guidance of the limbs. For example elastic elements in the legs of the posture garment may be coupled to elastic elements in the pelvic or core region of the posture garment. Similarly, elastic elements in the arms of the posture garment may be coupled to elastic elements in the shoulder girdle of the posture garment.
Each leg of the posture garment may be provided with an attached (e.g. integrally formed or permanently attached) foot part or strap passing beneath the arch of the wearer's foot, to prevent the garment from riding up the wearer's legs during arm and trunk movements. Similarly the arms of the posture garment may be provided with an attached (e.g. integrally formed or permanently attached) full or partial glove or strap passing between the wearer's fingers and/or fingers and thumb, to prevent the garment from riding up the wearer's arms during movement.
All of these elastic elements may be assembled or constituted in any suitable way, e.g. each being separately fabricated a single piece of suitable elastic material, for example elongate strips or bands. As another alternative, fabric pieces used to make the posture garment and which are cut to a pattern may each contain at least parts of different ones of the elastic elements, so that one or more or all of the elastic elements are assembled from a plurality of different fabric pieces. The posture garment may, comprise a base layer or layers of suitable fabric, e.g. a breathable and moisture wicking fabric comprising stretchable yarn comprising resiliently stretchable fibres such as Lycra (RTM) (elastane), to which the elastic elements are attached by any, suitable means, such as by heat bonding or by stitching. The base layer material may be more easily stretchable than the material from which the elastic elements are formed.
In a second independent aspect, the present invention provides a weight for use in a sports training or physiotherapy garment (hereafter “weighted garment”), the weight comprising a body formed from an elastomer, in which the body contains an embedded plurality of pieces of a harder, denser material, each piece having a minimum dimension of at least 1.5 mm (e.g. 2, 2.5, 3, 3.5, 4, 4.5 or 5 mm) and in which the individual pieces are movable relative to one another, whereby the body retains its flexibility. The harder, denser material pieces increase the overall density of the body and thereby reduce the bulk of a weight having a given mass. The weight, when attached to the weighted garment, is therefore less apt to obstruct movements of the garment wearer. The number and/or size of the individual embedded pieces of the harder and denser material may be selected so as to adapt the mass of the weight to the wearer's individual training or physiotherapeutic needs. The individual embedded pieces are also of sufficient size to be felt with the fingers, through the elastomer. A user of the weighted garment, and/or their physiotherapist, sports coach, personal trainer etc., therefore can easily tell by touch the extent to which the body is loaded with the harder and denser material, and hence gain a more precise indication of the overall mass and density of the body than is obtainable by simply weighing it in their hand. At the same time, the overall flexibility of the body is substantially unaffected by the presence of the harder, denser material; so that the weighted garment is comfortable to wear and the weights themselves present a low risk of injury to the wearer during exercise.
The elastomer may be translucent or transparent, so that the embedded pieces are visible within it; the minimum size of the pieces assisting them to be seen individually by the unaided eye.
The elastomer may comprise a silicone rubber.
Some or all of the embedded pieces may be linked together in an articulated way, e.g. forming links in an embedded chain or links in embedded chainmail. Alternatively some or all of the embedded pieces may be unconnected with each other, apart from by virtue of being embedded in the elastomer. This may make them easier to feel and/or see individually.
The embedded pieces may be arranged in a single layer or in a low number of layers (e.g. two, three or four), so that the overall thickness of the body of the weight may be kept small. The thickness dimension of the body of the weight may be substantially less than the two other orthogonal dimensions (the length and breadth of the body of the weight). The thickness profile of the weight may therefore be kept low. For example, the weight may be generally flat when not flexed.
The embedded pieces may be substantially spherical, e.g. formed by ball bearings. The embedded pieces may be formed from any suitable high density material; e.g. metals including iron, steel, stainless steel, lead, gold, tungsten, mercury (in a suitable container) and depleted uranium; alloys or mixtures of such metals; or ceramics such as silica or alumina; or concrete or natural or artificial stone, or assemblies or mixtures of any of these materials.
The weight may comprise a member of a set of weights. The set may comprise weights of various different predetermined shapes, each respectively adapted for use in a different predetermined position on the wearers' body; e.g. associated with a different muscle, muscle group, joint, bone, piece of connective tissue, or other feature of the musculoskeletal anatomy. A different one or combination of the differently shaped weights may be used together in association with each particular musculoskeletal anatomical feature respectively. This may reduce the number of differently shaped weights required; improving economy and ease of manufacture and use.
The set of weights may comprise different predetermined masses each respectively adapted for use at one or more of the predetermined positions; and/or different predetermined masses used to match the mass at a given predetermined position to the wearer's particular needs.
The maximum dimension of the embedded pieces in the possible range of differently sized embedded pieces used to tailor the mass of a given weight in the set may be 30 mm or less; for example 29, 28, 27, 26, 25, 24, 23, 22, 21, 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, or 6 mm; or at 0.5 or 0.25 mm increments above or below any of these dimensions. For example the embedded pieces may be ball bearings of 9.5 mm diameter, or ball bearings of any of the other diameters mentioned above. This again keeps the thickness profile of the weights low.
The number of embedded pieces in a given weight of the set (e.g. for use in a particular position in the weighted garment) may be kept the same when tailoring the weight to provide a different mass. This allows the weights in the set to be readily ranked in order of mass by feeling or viewing the size of the embedded pieces.
Alternatively, the size of the embedded pieces in a given weight of the set may be kept the same when tailoring the weight to provide a different mass. This allows the weights of the set to be readily ranked in order of mass by feeling or viewing the spacing between the embedded pieces.
The invention also extends to weighted garments comprising weights or sets of weights as described above.
In yet another aspect, the invention provides a sports training or physiotherapy garment comprising a fabric base and pockets for the reception of weights, the garment further comprising strips of relatively inextensible material forming a network interconnecting the base material within the pockets, in which the majority of the strips run generally longitudinally of the wearer's limbs and torso and form a branched network with bases mainly originating at the wearer's shoulders and/or hips; and wherein the network does not completely encircle the wearer's limbs and torso. The weight pockets may nevertheless be positioned all around the wearer's body, e.g. to the front, back, and/or sides.
The networks of the relatively inextensible strips may be provided (i) in legs of the garment, transmitting weight forces to the wearer's pelvis, and (ii) in the remainder of the garment transmitting weight forces to the wearer's shoulder girdle.
When the networks (i) and (ii) are not interconnected by any of the relatively inextensible strips, the garment may be provided either in a one piece configuration, or in a two piece configuration comprising a separate jacket and trousers.
When the networks (i) and (ii) are interconnected, the lower body and leg weights are provided with additional support.
Both the fabric base and the network of strips of relatively inextensible material may be formed from panels of textile fabric material cut to a pattern and joined together by seams.
A strip of the relatively inextensible material may be provided in a shoulder region of the garment, this strip having a higher elasticity than the strips forming the remainder of the network.
The invention and some of its advantages and optional features may be further understood from the following description of illustrative embodiments, made with reference to the drawings, in which:
As shown in
F=K·

where F is the test load, K is the material elastic constant in the course direction the force required to stretch a piece of the material 1 m wide by 100% of its original length in the course direction), Δ is the elongation (as a proportion of its original length) of the test sample under the test load, and w is the width of the test sample. Hence for the GGAQ SENSITIVE® PLUS material:
K=(F)/(·w)
K=(15)/(1.25*0.05)=240N/m
for the Art. NYAL material K=187.5 N/m
Some or all of the following elongate elastic tension elements may be provided: an elastic element forming a waistband 1 of the posture garment; an elastic element 2 running from the waistband up the back of the posture garment over the wearer's spine; an elastic element 3 running from the waistband up across the wearer's abdomen and over the wearer's sternum; an elastic element forming a band 4 passing laterally across the bottom of the wearer's shoulder blades; a pair of elastic elements 5a sloping in diagonally opposite directions upward from the small of the user's back from element 2 to element 4; and a further pair of elastic elements 5b sloping in diagonally opposite directions downward from the small of the user's back from element 2 to element 1. This arrangement of elongate elastic tension elements helps the user to hold their spine erect and to control movements of their trunk. The waist band 1, posterior longitudinal tension element 2 and anterior longitudinal tension element/support 3 provide horizontal and vertical feedback to the spine and torso, to enhance upright posture and core control.
Element 3 may be divided longitudinally to allow the wearer access for putting on/taking off the posture garment. A stretchable zipper, length of hook and loop fastening, buttons, poppers or the like may run the length of element 3 for releasably fastening the two parts together.
The wearer's lower core movement guidance and feedback control may be further enhanced by additional elongate elastic tension elements interconnected over the abdominal muscles and lower spine, for example provided as: looped bands 6 running in parallel across the wearer's lower back, substantially at right angles to element 2, then around the wearer's sides, from where they slope downwardly on each side of the wearer's abdomen to meet at element 3, thereby forming substantially parallel V-shapes. For example, three or four such looped bands 4 may be provided.
For additional guidance and feedback control of the wearer's shoulder girdle, a further pair of elongate elastic tension elements 7 may slope in diagonally opposite directions, upwardly across the user's upper back, approximately from where elements 2 and 4 meet each other; then over the user's shoulders, converging downwardly so as to connect to the upper end of the anterior longitudinal tension band/support 3, forming a V-shape over the wearer's chest, A further pair of such elongate elastic tension elements 8 may slope in diagonally opposite directions, downwardly across the wearer's upper back, from approximately where elements 2 and 4 meet each other, under the armpits, and then curving upward across the wearer's chest, to meet the elements 7. In a modification shown in
Elastic tension elements for position feedback and control of the arms may be articulated and coupled with the shoulder girdle and trunk via elongate elastic tension elements 9 at the front sloping downward and outward towards the upper part of the upper arm from the elements 8; and by corresponding elongate elastic tension elements 10 at the back, sloping downward and outward from near the upper end of the posterior longitudinal tension element 2, crossing the shoulder girdle elements 7 and continuing downward and outward towards the upper part of the upper arm.
The posture garment may have sleeves comprising an elongate elastic tension element 11 looped into a gamma-shaped configuration, having its ends joined to the coupling elements 9, 10; the crossing point of the gamma lying on the outside of the upper part of the upper arm, and the loop of the gamma passing around the lower part of the upper arm. A further elongate elastic tension element 12 may be looped into a figure-of-eight configuration, with its crossing point lying on the outside of the sleeve forearm portion, its upper loop passing around an upper portion of the forearm portion, and its lower loop passing around the sleeve lower forearm portion. A further elongate elastic tension element 13 may be helically looped around the sleeve so as to interconnect elements 11 and 12. Element 13 may thus join with element 11 at the inner side of the lower portion of the upper arm, passing around the back of the arm and then across the upper part of the forearm, to join element 12 towards the inner side of the upper part of the forearm. In the modification shown in
The posture garment may have legs comprising elongate elastic tension elements coupled to elongate elastic tension elements in the pelvic or core region of the posture garment. For example the elastic elements providing enhanced feedback and positional and/or postural control of the wearer's legs relative to their trunk may comprise such an elongate elastic tension element 14 running from belt-like element 1 at the hip, down the outside of the wearer's leg, Thus the elastic elements of the trunk are connected to elastic elements in the legs of the posture garment. The posture garment may further comprise such an elongate elastic tension element 15 running down the wearer's inside leg across the knee. An elongate elastic element 16 may slope diagonally from an outer front region of the element 1, around to the back of the leg by successively crossing the wearer's hip and element 14, the wearer's lower buttock, and the inner part of the hack of the thigh, to join the upper end of element 15 on the inside leg. A further elongate elastic tension element 17 may run diagonally from a rear centre section of the element 1, across the wearer's buttock, across the element 16 and across the wearer's rear outer thigh, to join the element 14. A further elongate elastic tension element 18 may run diagonally from an outer rear section of the element 1, across the wearer's hip and the element 14, and then across the wearer's thigh, to join the upper end of element 15 and the lower end of element 16. A further elongate elastic tension element 19 may slope downwardly and outwardly from a central front section of the element 1, across the wearer's thigh and the element 18, to join element 14 near the lower end of element 17, slightly above the wearer's knee.
A pair of elongate elastic tension elements 20 may be provided sloping diagonally in opposite directions relative to the axis of the wearer's lower leg and crossing one another over the wearer′ shin; and a pair of such elements 21 sloping diagonally in opposite directions relative to the axis of the wearer's lower leg and crossing one another over the wearer′ calf. Both elements 20 and 21 may have a pair of ends originating at element 14 and an opposite pair of ends originating at element 15.
The legs of the posture garment 100 may be provided with stirrup-like foot portions 104 which pass beneath the arches of the wearer's feet, so as to anchor the garment legs and prevent them from riding up the wearer's legs during exercise, A stirrup-like elongate elastic tension element 22 may pass beneath the arch of the wearer's foo within garment foot portion 104, so as to interconnect the lower ends of elements 14 and 15. The stirrup-like tension elements 22 provide feedback and support to the foot arches to stimulate arch support of the foot and promote medial arch control during walking and running activities. The tension element 22 creates an upward thrust to help support the “suspension-like” mechanics of the foot arches; as opposed to foot orthotics which work from under/beneath the foot. Similar (partial) glove-like or strap-like anchoring extensions (not shown) may be provided at the bottom ends of the arms of the posture garment.
The seams between the various pieces of material may be secured by any suitable means, such as overlock stitching. A suitable stitch thread is ELOFLEX®, available from Coats Group PLC, www.coats.com; though many other suitable alternatives are available. Suitable bonding adhesive e.g. for the zip placket and trouser lining, and/or seams more generally, is seam bonding tape available from Bemis Associates UK Limited, 3-5 Turnpike Close, Grantham, U.K NG31 7XU, www.bemisworldwide.com; although again, many other suitable alternatives are available.
Turning now to the weights forming the second aspect of the present disclosure,
As shown in
The above described moulding tools and process may be readily adapted to produce weights containing more than a single layer of dense pieces 216. For example, mould cavity 206b in die 202b may be suitably deepened and its inner (upper) surface provided with an array of protrusions shaped to form cavities in matrix component 213a, for reception of a further (full or partial) layer of dense pieces 216. One or more further matrix component layers thus may then be moulded on top of matrix component 213a. Other suitable elastomeric matrix materials may be used, for example TPE. Other known manufacturing processes may be used e.g. to automate and scale up production when required; e.g. by using more automated insert injection molding tools and equipment, e.g. with robotic placement (or other suitable automatic feeding/placement) of the dense pieces. Although a generally square weight is shown in
Additionally or alternatively it may be shaped for minimal interference with the wearer's limb and body movements, and/or with the operation of associated sports or orthopaedic clothing, footwear, headgear, equipment, prostheses, tools, backpacks, vehicles, furniture or the like used by the wearer.
The weighted garment is constructed from a number of base panels secured together by overlooked internal seams:
A zip or other suitable fastener or set of fasteners may be provided at the meeting edges of the left and right breast and abdominal panels 57, 59. The upper part of the garment may thereby be opened up to allow the user to put on or take off the weighted garment 300.
Certain parts of the weighted garment 300 subjected to high strains in use may be made from an even more breathable and elastic material, for improved performance.
A suitable material for these parts is for example product article 6345 POWER-NET supplied by Piave Maitex S.R.L, of Via Torino, 125, 21042 Caronno Pertusella (VA), Italy www.piavemaitex.com. This material has a nominal weight of 125 g/m2 and is warp knitted from PA 88%+EA 12% yarn. In the example shown in
For ease of manufacture, and to enable simplified user selection and substitution of weights of different masses for use at a particular location in the weighted garment 300, although the weighted garment has quite a large number of weight pockets and corresponding weights (34 as shown in
Shape 50 used on the chest and shoulder blades (4 off, each containing for example 370 g of high density material, for example 81 stainless steel ball bearings of 9.5 mm diameter);
Shape 51 used on the upper and lower torso, mainly at the rear, but also extending around the sides to approach the lower chest and abdomen (4 off, each containing for example 660 g of high density material, for example 186 stainless steel ball bearings);
Shape 52 used on the buttocks, but also extending forwardly around the hips, towards the groin (2 off, each containing for example 570 g of high density material, for example 123 stainless steel ball bearings);
Shape 53 used around the front and sides of the thighs (6 off, each containing 326 g of high density material, for example 92 stainless steel ball bearings);
Shape 54 used on the deltoids, upper arms, backs of the thighs and calves (10 off, each containing 222 g of high density material, for example 48 stainless steel ball bearings)
Shape 55 used on the forearms and lower legs (8 off, each containing 275 g of high density material, for example 60 stainless steel ball bearings).
Other suitable combinations of weights are also possible, with correspondingly shaped weight pockets being provided in the garment at the required locations accordingly. For example:
Shape 50 used on the chest and shoulder blades as shown in
Shape 52 used in place of shape 51 in the positions shown on the upper and lower torso, as well on the buttocks and hips (6 off);
Shape 55 used in place of shape 53 around the front and sides of the thighs (6 off);
Shape 54 used on the deltoids, upper arms, backs of the thighs and calves as above, but also used in place of shape 55 on the forearms and lower legs (1.6 off).

The disclosed posture garments and weighted garments therefore fulfil separate but complementary functions. The posture garment provides enhanced tactile and kinaesthetic feedback for dynamic guidance of the wearer's posture and limb and body movements; with little or no significant resistance to such movements. The weighted garment provides physical resistance for strengthening and toning the wearer's musculoskeletal system or selected parts of it. The garments may be used separately, but when used together, the posture garment can provide position and motion feedback and guidance which enhances and optimises the benefits of the weighted suit, by helping the resistance exercises to be performed with the correct movement patterns and postures, thereby enhancing their beneficial effects and minimising risk of injury. Together with some initial training, the posture garment acts as a pseudo personal trainer or coach, helping the weighted garment to be used to best effect. The posture garment may be used without the weighted garment for feedback and guidance of physical exercises, sports techniques and physiotherapy not requiring additional equipment, or guiding such activities which use other equipment, such as training weights, golf clubs, cricket bats, tennis racquets, medicine balls, running and exercise machines, ruck-and-maul machines, etc. For an experienced user or where a human coach/trainer is available, or in the absence of better options, the weighted suit may be used on its own for toning and strengthening the musculoskeletal system.
