Electromyographic Analysis of Scapular Muscles During Closed Kinetic Chain Exercises

For all MVICs, five seconds of each repetition were included in the analysis and the maximum value of three repetitions was taken. For all exercises, the middle 3 seconds of the 5 second data collection period were included in the analysis and the average muscle activation level of the three repetitions was recorded. The average signal amplitude of each exercise was divided by the MVIC of each muscle of interest to obtain the %MVIC value.
