Testing a New Way of Eccentric Resistance Training to Increase Muscle Damage and Growth in Young Adults Aged 18 to 35

What this Trial Is About

This research aims to compare a new method of weight training with typical weight training to see if it causes more exercise-induced muscle damage, which may help build bigger muscles. It also explores how muscle soreness affects daily activities in young adults aged 18 to 35 who have prior resistance training experience. The study is conducted by the New York Institute of Technology and involves healthy volunteers. Participants will be randomly assigned to one of two groups fast eccentric resistance training or slow eccentric resistance training. The study includes three lab sessions, each lasting 45 minutes. Sessions involve warm-up treadmill walking, maximal voluntary contraction tests on the chest press, and sets of eccentric lowering bench press exercises at 75% of maximum effort. After sessions two and three, participants rate muscle soreness for three days and answer questions about how the soreness affects their activities. During participation, individuals complete demographic questionnaires, muscle soreness self-assessments, and strength testing. The primary outcomes measured are muscle soreness over three days following training and changes in maximal voluntary isometric contraction before and immediately after interventions. Follow-up is conducted via two email questionnaires after sessions two and three. The total commitment includes three lab visits plus follow-up assessments. Safety is monitored by excluding those with injuries or cardiovascular issues that would prevent pain-free training.
