Cross-sectional study examines body composition and its relationship with physical performance in adult males, indicating significant associations.
Key Points
This study investigates the relationship between body composition and physical performance in Chinese adult men.
Cross-sectional study with 2,362 adult males from fitness assessment programs in Hengyang, China.
Body composition was assessed using bioelectrical impedance analysis, measuring fat percentage, fat mass, and muscle mass.
Physical performance was evaluated through tests like handgrip strength, vertical jump, and VO₂max; associations were analyzed using regression models.
Higher body fat percentage is associated with poorer performance in vertical jump, push-ups, and VO₂max (p < 0.001).
Skeletal muscle mass positively correlates with strength outcomes, particularly handgrip strength (β = 0.384, p < 0.001).
PCA reveals distinct clustering of adiposity-related variables and performance indicators, indicating strong predictors of strength and aerobic capacity.
