The present disclosure relates generally to massage devices and, more particularly, to a barbell massage roller and at least one method of using a barbell massage roller.
Massage therapy typically involves the manual manipulation of the soft tissues of the human body, such as muscles, tendons, ligaments and connective tissue. Massage therapy has long been employed as a way to relieve ailments of the human body related to tight, overstimulated or otherwise strained muscles. Furthermore, massage therapy has long been employed as a way to reduce pain, stress and to rehabilitate various injuries. Excess neural tone or residual muscular tension can exist as an after-effect of exercise, stress or muscle disuse when muscles are kept in a shortened state (e.g., prolonged sitting). The kneading of muscles and other soft tissues has proven to be directly beneficial to the musculoskeletal and nervous systems by way of relieving excess neural tone in the muscles and connective tissues. Furthermore, the kneading of muscles and other soft tissues has also proven to be beneficial toward the circulatory and lymphatic systems by way of increasing substance exchange between the cells and by increasing blood circulation.
Massage therapists, sometimes called masseurs, often treat clients by way of various techniques of manual manipulation of the muscles and soft tissues of the human body. In this regard, masseurs typically use their hands, forearms, fingers and elbows to knead the muscles and soft tissues. For example, myofascial release is a technique often practiced by masseurs which employs sustained pressure in order to release painful trigger points, which are localized areas of clenched or overstimulated muscle fibers. The myofascial release technique is also simple enough that it may be self-administered.
The administering of self-massage (e.g., without the employment of a masseur) through the use of manually employable mechanical massage devices has provided users an avenue toward self-treatment of the aforementioned ailments of the human body. Such mechanical massage devices typically provide a way by which the user can apply mechanical pressure to their body to knead the muscles and soft tissue, or to use directed pressure to release trigger points. This allows users to self-administer various massage techniques such as effleurage (longitudinal gliding), kneading, trigger point therapy, myofascial release and cross-fiber friction techniques. Many of these mechanical massage devices often utilize rolling elements, typically in the form of rollers, which are intended to roll about their axis in order to deliver mechanical pressure by direct physical contact with external surfaces of the human body. These devices, generally known as massage roller devices, have become ubiquitous in the field of physical therapy and have also gained popularity in the sports and fitness industry because of their ability to physically relax individuals, as well as counteract or relieve body pains.
Massage roller devices typically fall into one of three categories. The first category of massage roller devices typically relates to stick massage rollers. Stick massage rollers are often relatively smaller, as compared to other known massage roller devices, and are typically made up of one or more rollers which are rotatably mounted to a central axle, much like a conventional rolling pin. Typically, the central axle is fitted with one or more handles at each opposing end outside of the one or more rollers. During use, the user typically holds the one or more handles and moves the one or more rollers over some surface of their body in a rolling pin like motion. The second category of massage roller devices typically relates to foam rollers, often simply referred to as massage rollers. Foam rollers/massage rollers are typically made up of a cylindrically-shaped roller body which is relatively larger in diameter than most stick massage rollers, and have no central handle or handles like a stick massage roller. Foam rollers/massage rollers are typically intended to roll about their axial plane over a flat surface. In this regard, during use, foam rollers/massage rollers are typically positioned to be sandwiched between the user and a wall or a fixed support surface such as the floor, thus allowing the user to move some surface of their body over the outer surface of the foam roller/massage roller by way of lateral motion of their body. The third category of massage roller devices typically relates to massage balls. Massage balls often come in various sizes and are typically spherically-shaped. Similar to foam rollers/massage rollers, massage balls typically also rely on the use of a fixed support surface such as the floor, whereby during use the user may sandwich the massage ball between a wall or the fixed support surface and some surface of their body, and then proceed to move the surface of their body over the massage ball.
Various challenges and limitations exist, however, with regard to using known versions of such aforementioned massage roller devices, particularly relating to their overall lack of versatility.
Stick massage rollers rely on the user's hands and arms in order to stabilize and apply pressure to the body. Stick massage rollers are held in the user's hands, as previously discussed, enabling the user to direct and manually roll the stick massage roller over the affected area of the body while the muscles in that area remain relaxed. Deep tissue massage is better performed on muscles when they are in a passive or relaxed state. However, due to the need for stick massage rollers to be held with the user's hands, a user has limited access to certain areas of their body when attempting self-massage (e.g. the user's back, under the user's arms, the user's arms themselves or the user's shoulders). Furthermore, the user is limited in that any pressure applied to the surface of the user's body is applied by the user's own muscles, thus not fully enabling the user to relax during self-massage. This therefore tends to limit stick massage rollers to be most effective for massaging the smaller muscles and connective tissues of the limbs.
Foam rollers/massage rollers tend to be limited in that they are primarily intended to be used against a fixed support surface such as a floor or a wall, as previously discussed. These foam rollers/massage rollers rely on directed force applied by the user against the fixed support surface, or on the user's body weight, when used in conjunction with the fixed support surface to perform massage techniques, such as continuous rolling methods. The foam roller/massage roller has the mechanical advantage of pressure which is applied by the body weight of the user, as well as being well-suited to reach a user's back. Its method of use, however, allows it limited access to certain portions of the human body, such as the inner thigh or tops of the shoulders. Additionally, most versions of this kind of massage roller have planar surfaces which are either flat or covered with nodules (e.g., some of which are shaped/contoured too sharply or aggressively and may cause some users unnecessary discomfort when pressure is applied to their body). As such, this tends to limit their ability to perform pinpoint massage methods as well as limiting their ability to reach smaller inner contours of the human body. Furthermore, under most circumstances, foam rollers/massage rollers often require the user to support their own body weight during use. Deep tissue massage is better performed on muscles when they are in a passive/relaxed state, as previously discussed. As such, if the user's muscles are being used to resist the effects of gravity, these muscles are in an active state which makes it difficult for the user to relax targeted muscles when the user is physically rolling atop a foam roller/massage roller.
Since massage balls are typically spherically-shaped, as previously discussed, they often lack the relatively larger lateral surface area that some of the aforementioned kinds of massage roller devices typically provide. While their spherical shape makes them particularly useful for reaching smaller contours of the human body, such as the bottom of the foot, massage balls are inherently less stable than other kinds of massage roller devices because of their spherical shape. As such, massage balls tend to be limited and more well-suited for pinpoint massage methods such as trigger point therapy and deep tissue massage. Their spherical shape, however, makes them more difficult to use for long continuous rolling massage methods, i.e. effleurage (longitudinal gliding massage), in comparison to other kinds of massage roller devices, such as foam rollers/massage rollers.
With at least the aforementioned challenges and limitations in mind, there is a continuing unaddressed need for a massage roller device which is capable of providing the user with more effective ways in which to administer self-massage. Such a massage roller device should be capable of being particularly effective in relieving pain and discomfort associated with tight muscles, trigger points or other connective tissue or soft tissue ailments. Additionally, there is a continuing unaddressed need for a massage roller device which is more versatile than other massage roller devices, and is thus capable of providing the user with the benefits of the directed manual application on relaxed muscles that a stick massage roller typically provides, the mechanical advantage and use of continuous rolling methods that a foam roller/massage roller typically provides, as well as the pinpoint massage methods and advantages of a smaller surface area that a massage ball typically provides.
