Abstract
Aim:
The aim of the study was to
determine
the effects of
isometric training of quadriceps femoris muscle in various knee
positions. Methods: Twenty healthy university students were divided
into two groups. In sitting position maximal isometric contraction
exercises were performed the knee at 15º flexion (Group I) and
60º flexion (Group II). Training program was designed 3 times
a
week for 6 weeks. Following tests were performed before and after
training: one leg squat, step-up, step-down, one-leg hop, triple jump
and one repetition. Results: In both group, all test scores were
increased after training (p<0.05). On the other hand, Group II
had
higher scores compared with the Group I (p>0.05). Conclusion:
The
results of the study showed that maximal isometric contraction
training program at knee 60º flexion is much more effective to
increase physical capacity of the quadriceps muscle than at knee
15º
flexion.
