A total of 6 exercise conditions were
executed. The exercise protocol was
block randomized such that subjects
started with either shoulder internal
or shoulder external rotation exercises.
Within each block, low-,
medium-, and high-intensity rotation
exercises were performed in random
order. After completion of the first
block of exercises, the resting EMG
activity was recorded again for 5 seconds
before the second block of 3
randomly assigned exercises was
begun.
