Effect of early follicular phase of menstrual cycle on hip flexion-extension isokinetic parameters in sedentary female students.

Researchers conducted this observational study on sixty young females to detect the effect of the early follicular phase of the menstrual cycle on hip muscle performance. The Biodex Isokinetic dynamometer 4 pro was used. The authors used a dependent t-test and detected a statistically significant increase in the mean values of all hip flexion and extension isokinetic parameters at angular velocities 90°/sec and 180°/sec ( < 0.
