Baseline girth measurements of the lower leg were recorded at the 4 sites below the knee joint line. Subjects then performed an adequate warm-up and stretch for the lower extremity before exercising the triceps surae muscle group. To induce DOMS to both legs, subjects performed 20 submaximal, concentric, plantar-flexion contractions, followed by 4 or 5 sets of 35 eccentric triceps surae contractions at 90% of their estimated concentric, 1-repetition maximum weight.9 All plantar-flexion exercises were performed on a standing calf-raise machine (Cybex Eagle Fitness Systems, Medway, MA). Subjects did not pursue treatment for their calf muscle discomfort while participating in this study
