An interventional study of Fast Eccentric and Slow Eccentric in Eccentric Hypertrophy and Muscle Damage, sponsored by New York Institute of Technology. Recruiting at 1 site in United States. Open to participants aged 18 Years to 35 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-05-28.
Sponsored by New York Institute of Technology · Not applicable, Interventional, and Basic science
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.
Participants will come to the lab for 3 sessions, plus two email follow-up questionnaires.
Session 1 (45 minutes)
Session 2 (45 minutes)
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

Muscle soreness 1
Visual analog scale as indirect indicator of muscle damage. Scale of 1-5. Higher score = more soreness
Time frame: 1 day
Muscle soreness 2
Visual analog scale as indirect indicator of muscle damage. Scale of 1-5. Higher score = more soreness
Time frame: 2 days
Muscle soreness 3
Visual analog scale as indirect indicator of muscle damage. Scale of 1-5. Higher score = more soreness
Time frame: 3 days
Maximal Voluntary Isometric Contraction Change
Change in MVIC will be used to indicated muscle damage.
Time frame: pre-intervention, immediately after the intervention
