Abstract

The invention provides a real-time exercise coaching system on the basis of that the whole exercise course could be subdivided into 4 basic components: sprint (anaerobic or speeding), aerobic endurance (balancing aerobic endurance), compensating (compensating O₂ debt), and dynamic recovery. The real-time exercise coaching system of the invention enables a user to realize his/her current physiological state and change of fitness condition and then the user can further decide which action (sprint, aerobic endurance, and dynamic recovery) is to be taken next. The system of the invention instantly and continuously provides information that assesses a user'"'"'s current physiological state during exercising in view of the exercise situations and the environmental conditions (such as temperature, humidity, altitude and air quality).

1 to about +/−

20% of the average HR intensity of this state; and

a dynamic recovery state if the HR intensity decreases about 1% to about 20% than an average HR intensity during the aerobic endurance state for a time period that is longer than that of the sprint or compensating state; and

(c) an output module to display the real-time workload status including the sprint, the compensating, the aerobic endurance or the dynamic recovery status

7. The real-time exercise coaching system of claim 6, wherein the color levels are shown with fixed colors and/or blinking colors.

8. The real-time exercise coaching system of claim 7, wherein the color levels are 1 to 20 color levels, 1 to 10 color levels or 1 to 7 color levels.

9. The real-time exercise coaching system of claim 7, wherein the color levels are 1 to 5 color levels.

10. The real-time exercise coaching system of claim 7, wherein the color levels are 5 color levels.

11. The real-time exercise coaching system of claim 10, wherein the 5 color levels from the lowest to the highest level are sequenced as blue (B), green (G), yellow (Y), orange (O) and red (R) and the blinking color of the color level is denoted with the symbol “

*.”

12. The real-time exercise coaching system of claim 11, wherein when the user undergoing an anaerobic sprint enters into a mainly aerobic endurance stage, the color elevates to the next level with a fixed color, displaying from B to BG, from BG to BGY, from BGY to BGYO, or from BGYO to BGYOR;

when the user is engaging in an anaerobic sprint or compensating extra previously banked oxygen debt, the color elevates to the next level with a blinking color, displaying from B to BG*, from BG to BGY*, from BGY to BGYO*, or from BGYO to BGYOR*;

when the user is in dynamic recovery, the color decreases down one level with a fixed color, displaying from BG to B, from BGY to BG, from BGYO to BGY, or from BGYOR to BGYO.

13. The real-time exercise coaching system of claim 1, wherein the visual display of the output module can be further combined with an audio output display and/or a vibration output display.

14. The real-time exercise coaching system of claim 1, which further comprises one or more sensor module selected from a group consisting of a body temperature and sweating sensor module, a respiratory rate sensor module, an environmental temperature and humidity sensor module, and a movement speed sensor module.

15. The real-time exercise coaching system of claim 14, wherein one or more of workout efficiency, workout intension, speed and total calorie navigation indicator can be further obtained by the process unit module and then the suggestions regarding workout efficiency, workout intension, speed or total calorie navigation indicator and optional current heart rate can be displayed by the output module.

16. The real-time exercise coaching system of claim 15, wherein the workout efficiency is calculated according to the equation of (TS/DRS)+k, wherein TS refers to temporal speed denoting an average rate within 30 seconds;

DRS refers to database related speed (DRS) denoting to average referring speed that corresponds to a lowest detected heart rate (DHR) representing the lowest heart rate within 30 seconds after starting to run the system.
