Traditional tests of different physical determinants (force, speed and power) in sports science and athletic development is presented. Such methods and technologies might have some shortcomings in that they lack both kinetic and kinematic specificity to both functional and athletic tasks. The authors argue that new technologies opens up for new pos...

The ever-increasing athletic performances in speed, strength and skills used in sports performance around the world has made the athlete more stressful to achieve their own objectives. This stress and pressure on the athlete's body will certainly result in injuries. The research is meant to identify the Biorhythm, its different Cycles and how to or...
