The disclosure relates in general to a physical activity management system and a method for performing the same.
Exercising is an important way to maintain a healthy condition. Recently, more and more measures can evaluate the level of exercising for an individual. Borg scale is a well-known quantitative measure of perceived exertion during physical activity. A doctor or a sport coach often use Borg scale to assess the intensity of training and competition. However, the Borg scale is related to the feeling of individuals performing exercise, rather than an objective level of evaluation for the physical activity. Therefore, setting a system for evaluating the physical activity of individuals performing exercise in a more objective level is still in highly demands.
The disclosure is directed to a physical activity management system and a method for performing the same. In one embodiment, the physical activity management system uses parameters including a heart rate recovery and a respiratory rate recovery of a user to evaluate a suitable exercise solution for the user. The exercise solution may be modified according to an adjustment decision upon doing the physical activity every time. That is, the physical activity management system may coach the user practicing the physical activity in a personalized and objective way.

For example, a first target of the exercise intensity in the ES1 may be modified to a second target of the exercise intensity in the ES2 according to the adjustment decision. The adjustment decision for the target of the exercise intensity G may be calculated according to the achieving rate of the heart rate intensity H, the heart rate recovery R, and the respiratory rate recovery B.
The target of the exercise intensity G may be modified according to the following formula:

i≤1
Gi is the target of the exercise intensity at the ith time, Gi−1 is the target of the exercise intensity at the i−1th time, ΔG, is an adjustment decision for the target of the exercise intensity at the ith time.
G0 is an initial target of the exercise intensity given by a doctor or calculated by the physical activity management system according to the background information of the user.
ΔGi=ΔHi+ΔRi+ΔBi
ΔHi=Hi−Hi−1; Hi≤1
ΔRi=Ri−Ri−1; R0=R1
ΔBi=Bi−Bi−1; B0=B1
ΔHi is a difference between the achieving rate of the heart rate at the ith time and the achieving rate of the heart rate at the i−1th time.
ΔRi is a difference between the heart rate recovery at the ith time and the heart rate recovery at the i−1th time. R0 is an initial heart rate recovery. R1 is a heart rate recovery at the first time.
ΔBi is a difference between the respiratory rate recovery at the ith time and the respiratory rate recovery at the i−1th time. B0 is an initial respiratory rate recovery. B1 is a respiratory rate recovery at the first time.
In brief, the physical activity management system may keep detecting, calculating and coaching the user for exercising. That is, the physical activity management system may keep comparing the exercise status at the ith time (including Hi, Ri and Bi) and the target value at the i−1th time (including Hi−1, Ri−1, and Bi−1), to get the adjustment decision at the ith time ΔG1, and using the ΔG1 and Gi−1 to determine the target exercise intensity for the next time Gi. The adjustment decision ΔGi at the ith time is a value related to differences between the exercise status at the ith time (including Hi, Ri and Bi) and the target value at the i−1th time (including Hi−1, Ri−1 and Bi−1). In other words, the calculating unit 605 makes the adjustment decision ΔGi by comparing an achieving rate of heart rate in the exercise status Hi, and an achieving rate of heart rate in the first exercise solution Hi-1, comparing the heart rate recovery in the exercise status Ri and a heart rate recovery in the first exercise status Ri−1, and comparing the respiratory rate recovery in the exercise status Bi and a respiratory rate recovery in the first exercise solution Bi−1.
In one embodiment, a user A set the target of the exercise intensity G0 as 0.7, such as reaching 70% of the maximal heart rate, and the achieving rate of the exercise intensity H0 as 0.5 in a physical activity management system which may calculate the formula described above. Then, the user A wears the device including the physical activity management system to do exercise, and the physical activity management system may detect the exercise status of the user A, such as the achieving rate of the exercise intensity at the first time H1, the heart rate recovery at the first time R1 and the respiratory rate recovery at the first time B1, which are 0.33, 0.84 and 0.87, respectively. The physical activity management system may also calculate the adjustment decision at the first time ΔG1 by comparing the exercise status at the first time (including H1, R1 and B1) and the initial value including H0, R0 and B0. For example, ΔG1=(0.33−0.5)+(0.84−0.84)+(0.87−0.87)=−0.17. The target of the exercise intensity for the next time G1 may be a modified according to the adjustment decision at the first time ΔG1, and G1=0.7−0.17=0.53. At the second time of exercising, if the physical activity management system detects that the achieving rate of the exercise intensity at the second time H2, the heart rate recovery at the second time R2 and the respiratory rate recovery B2 at the second time of the user A are 0.33, 0.84 and 0.87, respectively, then the physical activity management system may also calculate the adjustment decision at the second time ΔG2. For example, ΔG2=(0.45−0.33)+(0.83−0.84)+(0.86−0.87)=0.10. The target of the exercise intensity for the next time G2 may be a modified according to the adjustment decision at the second time ΔG2, and G2=0.53+0.10=0.63.
In one embodiment, a user B set the target of the exercise intensity G0 as 0.6, such as reaching 60% of the maximal heart rate, and the achieving rate of the exercise intensity H0 as 0.3 in a physical activity management system which may calculate the formula described above. Then, the user B wears the device including the physical activity management system to do exercise, and the physical activity management system may detect the exercise status of the user B, such as the achieving rate of the exercise intensity at the first time H1, the heart rate recovery at the first time R1 and the respiratory rate recovery at the first time B1, which are 0.9, 0.92 and 0.89, respectively. The physical activity management system may also calculate the adjustment decision at the first time ΔG1 by comparing the exercise status at the first time (including H1, R1 and B1) and the initial value including H0, R0 and B0. For example, ΔG1=(0.9−0.3)+(0.92−0.92)+(0.89−0.89)=0.6. The target of the exercise intensity for the next time G1 may be a modified according to the adjustment decision at the first time ΔG1, and G1=0.6+0.6=1.2. Since G1≤1, G1 is determined to be 1. Then, the physical activity management system may keep detecting, calculating and coaching the user B in the following exercise procedure. At the second time of exercising, if the physical activity management system detects that the achieving rate of the exercise intensity at the second time H2, the heart rate recovery at the second time R2 and the respiratory rate recovery B2 at the second time of the user B are 0.85, 0.89 and 0.86, respectively, then the physical activity management system may also calculate the adjustment decision at the second time ΔG2. For example, ΔG2=(0.85−0.9)+(0.89−0.92)+(0.86−0.89)=−0.11. The target of the exercise intensity for the next time G2 may be a modified according to the adjustment decision at the second time ΔG2, and G2=1+(−0.11)=0.89.
The method for calculating the adjustment decision is not limited thereto. Any related method calculating with the G, H, R and B may be included in the scope of the disclosure.
In one embodiment, the exercise intensity G may be a heart rate intensity, and the achieving rate of the exercise intensity may be the achieving rate of the heart rate intensity.
In an embodiment, the present application provides a physical activity management system using the exercise intensity G, the achieving rate of the exercise intensity H, the heart rate recovery R, and the respiratory rate recovery B to analyze if the exercise solution is suitable for the user or not, and making an adjustment decision to modify the exercise solution. That is, a personalized exercise solution may be provided. Since the parameters for the adjustment decision includes the respiratory rate recovery B by using the sonic frequency sensing unit to detect the respiration of the user, the evaluation to the exercise status of the user may be more accurate comparing to merely using the feeling of the user in Borg scale to evaluate the exercise status. In this way, the physical activity management system of present application may coach the exercise solution for the user in a personalized way, and the user may get a health goal, such as, controlling the blood pressure, the blood sugar, the blood fat, the weight, or the waist circumference, improving the bone density and the depression, in a more efficient and safer way.
In summary, the physical activity management system disclosed in aforementioned embodiments may use multiple parameters including the exercise intensity, the achieving rate of the exercise intensity, the heart rate recovery, and the respiratory rate recovery to analyze if an exercise solution is suitable for the user or not, and making an adjustment decision to modify the exercise solution. That is, a personalized exercise solution may be provided. Since the parameters for the adjustment decision includes the respiratory rate recovery by using a sonic frequency sensing unit to detect the respiration of the user, the evaluation to the exercise status of the user may be more accurate comparing to merely using the feeling of the user in Borg scale to evaluate the exercise status.
