With exercise, there is a slight risk of muscle soreness or strain. We will mitigate risk of muscle strain by instructing the subjects to stop the exercise if they feel they are over-straining or begin to feel discomfort when performing the activity. The investigators will also be immediately available to assist, if needed, if the subject experiences discomfort during the exercise session. It is well known that repetitive contractions have a possibility of inducing delayed onset muscle soreness (DOMS). This is known to occur most often with eccentric exercises. Previous research has shown that there was no effect from DOMS using the intended protocol described and that a washout period of 24 hours was adequate with eccentric loading.
