%MVIC	Mean ± SD		Difference value	t	p	Effect size
	Y	YLTPS
UT	39.06±16.44	26.84±14.63	12.22	3.71	.00*	0.78

%MVIC, percentage maximal voluntary isometric contraction, SD, standard deviation; LT, lower trapezius; UT, upper trapezius; SA, serratus anterior; Y, y-raise exercise; YLTPS, y-raise exercise with lower trapezius taping after pectoralis minor stretching.
: significant difference.
