Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Maximum repetitions | 1 week | Evaluation of maximum repetitions of knee flexion-extension in isokinetic dynamometer. Volunteers were assessed on Monday (pre evaluation - baseline), on Wednesday performed a session of exercises and on Friday were assessed again (final evaluation). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Median Frequency | 1 week | Evaluation of median frequency by surface electromyography of quadriceps femoris muscles during maximum repetitions of knee flexion-extension in isokinetic dynamometer. Volunteers were assessed on Monday (pre evaluation - baseline), on Wednesday performed a session of exercises and on Friday were assessed again (final evaluation). |
