OBJECTIVE: To evaluate the improvement rate of quadriceps muscle peak torque in
healthy subjects and patients with burn injuries after an isokinetic training
programme. SUBJECTS: Thirty male volunteers, 15 healthy and 15 subjects with burn
injury after complete healing, participated in the study.
METHODS: Concentric and
eccentric torque of quadriceps was measured for both groups using an isokinetic
dynamometer before and after 6 weeks of isokinetic training. The tests were
performed at angular velocities of 30 degrees /s and 90 degrees /s. RESULTS:
There was a significant increase in the quadricep speak torque for both groups at
both angular velocities after isokinetic training. During eccentric contraction
at angular velocities of 30 degrees /s and 90 degrees /s the percentage
improvement in the burned group was higher than in the healthy group(p = 0.003
and p = 0.0008, respectively). During concentric contraction at an angular
velocity of 30 degrees /s the percentage improvement in the burned group was
higher than the healthy group (p = 0.020). However, during concentric contraction
at an angular velocity of 90 degrees /s there was no significant difference
between the groups (p = 0.742). CONCLUSION: The isokinetic training programme was
effective in increasing the concentric and eccentric peak torque of the
quadriceps muscle for healthy subjects and patients with burn injuries.
