Comparison of means (± standard deviation) for electromyographic activity of eight muscles during the three tasks for males and females.

	Lunge		Side‐Step		Step‐Down
	Male	Female	Male	Female	Male	Female
Rectus Femoris	12±2	12±2	12±3	11±2	12±2	13±2
Rectus Abdominis	13±3	13±4	15±3	13±4	14±4	15±5
External Oblique	12±3	12±4	12±5	13±4	13±5	12±5
Erector Spinae	13±3	12±4	15±2	13±4	14±3	13±4
Tensor Fascia Latae	12±3	13±2	12±3	13±3	13±2	14±2
Biceps Femoris	12±3	13±2	12±3	12±2	13±3	14±2
Gluteus Medius	12±2	12±2	13±3	13±2	14±3*	14±3*
Gluteus Maximus	11±3	10±2	12±4	12±2	13±2†	13±2†

Data expressed as means (± standard deviation) percentage of maximum voluntary isometric contraction (%MVIC).

^*For gluteus medius muscle, statistically higher %MVIC for step down compared to lunge (p= 002) and side step (p=.006)

^†For gluteus maximus muscle, statistically higher %MV1C for step down compared to lunge, (p=002)
