Data are presented as normalized strength values (M ± SD) calculated by averaging the maximum force (N) of three trials then dividing by body weight (N) for each muscle, respectively.

^*Significantly greater than those listed below it.

^†Significantly greater than lower trapezius, supraspinatus, medial and lateral rotators.

^‡Significantly greater than medial and lateral rotators.

^§Significantly greater than lateral rotators.
