Abstract
This study examined the activity of muscles in the hip joint during step-up exercises. Of 13 healthy males, rectified filtered electromyography of the gluteus maximus, gluteus medius, adductor magnus, tensor facia latae, and rectus femoris were recorded in nine step-up patterns that differed in step direction and step height. Two-factor factorial ANOVA was used as the statistical analysis with a significant level of 0.05.
The result showed that step direction significantly affected muscle activity in the gluteus medius, and tensor facia latae. Muscle activity in the gluteus maximums, gluteus medius and tensor facia latae were significantly increased by higher step height. Interaction effects between step direction and step height were detected in the muscle activity of the adductor magnus and rectus femoris.
Step direction and step height would differently affect the activity of muscles in the hip joint during step-up exercise.
