i. Improves performance in sports: principles of biomechanics tell us about right techniques, effective and result oriented posture to get more efficient results by applying minimum muscular force which in turn improves performance in sports.
ii. Improvement in technique: with the help of biomechanical principles the physical education teacher corrects the mistakes. This helps in improving the game and performance of the player.
iii. Development of improved sports equipment: the principles of biomechanics are used to modify the sports equipments. For example, tee shirts, studs, spikes, swimming costumes, hockey sticks, different size footballs and low weight helmets for protection.
