Variation in adiposity indices, fitness index and Q-angle with types of contact sports
Common to every sport is the quest for high performance and desire to avoid injury. Low body adiposity has been connected to performance in sports, while increasing Q-angle is associated with increased lateral patella-femoral contact pressure and risk of knee injury. This non-experimental comparative study compared adiposity indices and Q-angle among football, volleyball and basketball players. A total of 68 male students comprising of 30 amateur footballers players, 19 amateur basketball players and 19 amateur volleyball players participated in the study. Selected and measured adiposity indices were body mass index, waist-hip ratio, percentage body fat, lean body mass and conicity index were measured among the participants. Results showed significant differences in body mass index (P=0.001), body fat (P<0.001), fat mass (P=0.002), fat free mass (P=0.04) and body adiposity index (P=0.001) among the participants groups, with volleyball players possessing significantly higher mean values for all adiposity indices. There was no significant difference in Q-angle among the three groups of players. It appears high body adiposity is common with volleyball players compared to basketball players. Volleyball players possess higher risk of obesity and poor physical fitness while risk of knee injury is not associated with any of sports at amateur level.
