Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum repetitions	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).	1 week	No
Secondary	Median Frequency	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).	1 week	No
