Comparison of muscle activity and strength depending on neck rotation directions

Variable	Neck rotating directions			F	p

	Ipsilateral	Neutral	Contralateral
Biceps M (%MVIC)	73.82±18.53	78.44±16.04	78.96±16.21^*†	7.35	0.002
Triceps M (%MVIC)	24.83±20.80	27.01±24.28	27.05±24.08	1.71	0.197
Elbow flexor strength (lbs)	28.84±8.83	30.85±10.75	31.39±11.88^*†	7.54	0.002

Mean±SD: Mean±Standard Deviation, Biceps m: Biceps brachii muscle activity, Triceps m: Triceps brachii muscle activity.

^*p<0.05: significant difference between neutral and contralateral neck rotation, ^†p<0.05: significant difference between ipsilateral and contralateral neck rotation.
