Study of How Lower-Limb Muscle Mass Affects Muscle Strength, Aerobic and Anaerobic Fitness, and Jumping Ability in Healthy Adults Aged 18 to 30

What this Trial Is About

This research aims to explore how leg muscle mass relates to muscle strength, aerobic capacity, anaerobic power, and jumping ability in healthy young adults aged 18 to 30. The study also compares these physical performance measures between males and females to better understand sex differences in these areas. The findings are intended to enhance exercise guidance, performance evaluation, and support future sports and health science studies. Participants will undergo assessments including body weight and leg muscle mass measurement using a body composition analyzer. They will perform leg strength tests that measure muscle force during movement isokinetic and while stationary isometric. Additionally, participants will complete tests for aerobic fitness VO2 max, anaerobic power Wingate test, and a countermovement jump to evaluate jumping performance. During the study, participants will be evaluated at baseline using these physical performance tests. Researchers will monitor leg muscle mass alongside various measures of muscle strength, aerobic and anaerobic capacity, and jump ability. The study is expected to last from February 2026 to August 2026, with primary data collection completed by June 2026. The study involves healthy, recreationally active young adults and includes no blinding or placebo controls.
