Effect of positional role on isokinetic muscles torque production of selected movements of basketball players

Abstract

The present study compare the isokinetic torque production of major movements like knee extension, shoulder flexion and elbow extension among different playing position players in basketball and to find out whether positional role effect the muscular strength attribute of players.21 national level basketball players participated in the study voluntarily. For each player measurement of height, weight, age, and training age were taken, the test of isokinetic exercise for knee extension, shoulder flexion, and elbow extension was performed. The study found that the center performs significantly better than forward and guard players for knee extension and shoulder flexion movement and forward perform significantly better than guard for the same. No significant difference was found for elbow extension movement, but after normalization of isokinetic peak torque with body size, comparison of relative isokinetic peak torque showed that center and forward significantly perform better than guard players for isokinetic knee extension movement at 60os-1, whereas guard and forward players significantly perform better than a center player for elbow extension movement at 60os-1. Normalization for body size nullifies the significant difference in isokinetic peak torque produced for shoulder flexion movement at 60os-1.
