Comparison of Different Isokinetic Velocity Spectrum Exercises on Peak Torque Quadriceps Muscle

Abstract

Isokinetic exercises are those exercises, which are performed with a specialized apparatus that provides variable resistance to movement so that no maer how much effort is entered, the movement takes place at a constant speed. The Isokinetic peak torque is one of the important parameters to evaluate the athletic performance or to prevent knee injury. The clinical application of Isokinetic include documentation of patient progress, rehabilitation exercise regimens the use of normative data and analysis of force velocity or power velocity relationships. In the following study total of 40 patients were taken and were divided in four groups Group A (n=10) (Isokinetic training protocol I), Group B (N=10), Group C (n=10) (Isokinetic training protocol III) and Group D (n=10) (Isokinetic training protocol IV). Paired t-test was used to compare the effectiveness of peak torque within the groups. ANOVA test was used to find the relation between two variables i.e. different Isokinetic velocity spectrum exercises and peak torque. On applying ANOVA the result was found to be significant with F-vale 7.58 at p<0.05. In conclusion, modified velocity spectrum protocol starting from high velocity is more effective in increasing quadriceps peak torque than other three protocols.
