Table 2. Repeated measure analysis of variance comparison of isometric peak force of the shoulder internal and external rotator between with and without FHP conditions and shoulder sides(N=29)

Peak force values	Level	F	p value
Internal rotator (kgf)	FHP conditions	1.046	0.307
	Shoulder sides	0.777	0.401
	Conditions × sides	0.881	0.373
External rotator (kgf)	FHP conditions	5.724	0.008*
	Shoulder sides	1.514	0.201
	Conditions × sides	0.884	0.346
