ABSTRACT
The main purpose of this study is to find out the ratio of maximum isometric tension of quadriceps and hamstring at different angles of knee flexion, (300,450,600) with hip position in neutral and to find out the difference between maximum isometric tension of quadriceps and hamstrings in the dominant and non-dominant side. Study design was Cross sectional study with convenience sampling. The research setting was done at the Physiotherapy Department in All India Institute of Physical Medicine & Rehabilitation. Participants for this study include 50 healthy individual with 25 males and 25 females. The main outcome measures is Isometric strength was measured at different angles. Each measurement was repeated thrice and average was taken .then in dominant and non dominant sides were measured one side after other. Result shows that there was no significant difference between the dominant and non dominant limb strength of Quadriceps and hamstring in both male and females (p>0.05).The maximum isometric tension of Quadriceps is highest at 600 knee flexion (p<0.05) when compared to 300 and 450. The maximum isometric tension of hamstring is highest at 300 knee flexion (p<0.01) when compared to 450 and 600.
Key words: Maximum isometric tension, spring balance, Hip position in neutral.
