Comparing Two Eccentric Protocols on Muscle Damage

Summary

The purpose of this study will be to test whether a new way of weight training is more effective than typical weight training. The investigators expect that this new way will cause more exercise-induced muscle damage, which helps people build bigger muscles. Another purpose of this study will be to explore perceptions of how muscle soreness impacts participant activities of daily living.

Detailed Description

Participants will come to the lab for 3 sessions, plus two email follow-up questionnaires. Session 1 (45 minutes) * Complete a demographic questionnaire * Self-assess muscle soreness * Walk on the treadmill to warm-up * Maximal voluntary contraction on the chest press * Two sets of eccentric (lowering) bench press at 75% of max Session 2 (45 minutes) * Walk on the treadmill to warm up * Maximal voluntary contraction on the chest press * Three sets of 10 eccentric contractions at 75% of max * Repeat the maximal voluntary contraction on the chest press Session 2 Follow-up Rate muscle soreness for each of the three days following Session 2 Answer open-ended questions about perceptions of the muscle soreness Session 3 (45 minutes) Walk on the treadmill to warm up Maximal voluntary contraction on the chest press Three sets of 10 eccentric contractions at 75% of max Repeat the maximal voluntary contraction on the chest press Session 3 Follow-up Rate muscle soreness for each of the three days following Session 2 Answer open-ended questions about perceptions of the muscle soreness
