Abstract :Height-adjusted indexes that reflect muscularity and fatness have recently gained great momentum in exercise and sports sciences as these indexes are considered to more accurately predict general body composition insert ignore into journalissuearticles values(BC); status, compared to body mass index. The aim of the study was to compare BC components and height-adjusted indexes between young swimmers and non-athlete controls. Thirty-four young volunteers, consisting of eighteen swimmers insert ignore into journalissuearticles values(male n=8; female n=10); and sixteen college students serving as a control group insert ignore into journalissuearticles values(male n=8; female n=8);, participated in this study. BC and whole-body bone mineral density insert ignore into journalissuearticles values(BMD); were measured using DXA and height-normalized indexes of fat mass insert ignore into journalissuearticles values(FM); and lean mass insert ignore into journalissuearticles values(LM); were calculated. Two-way insert ignore into journalissuearticles values(group*sex); ANOVA was used to compare the BC components within and between the groups. No differences in body mass index insert ignore into journalissuearticles values(BMI);, age, and body weight were observed between the groups insert ignore into journalissuearticles values(p>0.05);. Swimmers had greater LM and lean mass index insert ignore into journalissuearticles values(LMI);, and lower total body fat mass percentage insert ignore into journalissuearticles values(FM%);, fat mass index insert ignore into journalissuearticles values(FMI);, and visceral adipose tissue insert ignore into journalissuearticles values(VAT); insert ignore into journalissuearticles values(p<0.01); compared to controls. BMD was similar in both groups regardless of sex insert ignore into journalissuearticles values(p>0.05);. Male swimmers had lower FM% and FMI, and higher LM than female swimmers insert ignore into journalissuearticles values(p<0.001);. BMD was correlated with BMI, LM, LMI, appendicular LMI insert ignore into journalissuearticles values(r=0.47, 0.55, 0.62, 0.60, respectively; p<0.001); and FM% insert ignore into journalissuearticles values(r=-0.35; p=0.04);. Swimmers had higher lean and lower fat mass and VAT compared to inactive college students with similar age. Accordingly, swimming improves BC components; however, it does not seem to increase bone mineral density due to the reduced weight-bearing effect.
