A model is presented of the force and power produced during a world record sprint to provide coaches and athletes with a method to determine how much force to use during strength training and what velocity to train at. In addition to specific velocity of strength training, the coach or athlete can estimate the biomechanical position of the athlete by determining that position for the relevant s...

This study examined the capabilities of an ultraendurance athlete to self-regulate their diet during an attempt on the record for the longest period of stationary cycling. The attempt required the athlete to complete at least 20 km/hr, with a 15 minute break allowed every eight hours. Laboratory tests determined a heart rate-oxygen consumption regression equation enabling calculation of energy ...

In the process of the multimedia physical education, the moving athlete detection is the key to tracking and recognizing the athlete. This task contributes to the gesture and action modeling and simulation. However, since the scene of sports events is complicated, the background is commonly affected by the noise and illumination changes, making the background difficult to remove. In order to so...
