Q.'Knowledge of biomechanics helps in the selection of players', Discuss in the context of any one game of your choice.

Biomechanics helps select players by revealing the structural and functional traits (height, limb length, force production) a specific sport's movements actually demand. …

The textbook states that knowledge of biomechanics gives teachers and coaches 'a better understanding of the human body in terms of structural and functional qualities as also the various internal and external forces that affect movement,' which 'helps a teacher and coach to select the players according to the requirements of the sport,' giving its own example: 'short players for gymnastics and tall players for Volleyball.'

Taking volleyball as the chosen game: a biomechanical understanding of spiking and blocking shows that a taller player, with a longer reach and higher standing/jump touch height, can contact the ball at a greater height above the net with less effort, giving a mechanical advantage for both attacking (spiking over blockers) and defending (blocking an opponent's attack). Biomechanics also explains why explosive vertical-jump technique (proper knee bend, arm-swing timing, and force application into the floor) matters more than raw height alone -- two players of the same height can have very different jump reach because of technique. For a position like libero (who plays only in the back row a …
