This document discusses a study on the relationship between body composition, foot angle, and functional efficiency in volleyball boosters and smashers. The study collected data on body composition, foot angle, and variables measuring functional efficiency (e.g. vertical jump, strength) from 25 boosters and smashers. It found a significant correlation between leg strength and body composition in boosters. It also found a significant correlation between standing broad jump and foot angle in boosters. However, it found mostly insignificant correlations for smashers and between other variables. The results suggest body composition and foot angle have limited relationships to functional efficiency in volleyball players.
