Lower-Limb Muscle Mass and Cardiovascular and Muscular Performance in Males and Females

The aim of this study will be to examine the relationship between leg muscle mass and muscle strength, aerobic capacity, anaerobic power, and jumping performance in young adults. In addition, these physical performance measures will be compared between male and female participants. Recreationally active young adults will be recruited to participate in the study. Body weight and leg muscle mass will be assessed using a body composition analyzer. Participants will perform isokinetic and isometric leg strength tests, an aerobic fitness test (VO₂max), an anaerobic power test (Wingate), and a countermovement jump (CMJ) test. This study aims to improve the understanding of the effects of leg muscle mass on physical performance and to identify possible differences between males and females. The findings are expected to contribute to exercise prescription, performance assessment, and future research in sports and health sciences.
