Peak normalized EMG measurements for all exercises and muscles

	Isometric		Dynamic
	IBA	IBK	FKE	CSS	ADP	ABP
Adductor longus	84 (7)*	118 (6)*†	33 (5)	13 (2)	86 (9)*	8 (1)
Gluteus medius	11 (2)	11 (2)	19 (4)	38 (5)*	12 (2)	88 (6)†*
Rectus abdominis	8 (2)	4 (1)	83 (7)†	4 (1)	12 (2)	10 (2)
External obliques	19 (4)	14 (4)	100 (8)†*	14 (3)	31 (5)	25 (5)

Values reported as mean normalized electromyography (standard error). IBA = “isometric adduction against a football placed between the ankles”; IBK = “isometric adduction against a football placed between the knees”; FKE = “folding knife exercise”; CSS = “crosscountry skiing on one leg”; ADP = “adduction partner”; ABP = “abduction partner”.

^* = significantly higher peak nEMG for this muscle than for other muscles during the exercise (p < 0.002).

^† = significantly higher peak nEMG during this exercise for this muscle than during any other exercise (p < 0.0001).
