Introduction: The purpose of this study was to investigate the relationship between active and passive body mass components and maximal aerobic consumption (VO2max) in adult male soccer players.
Methods: The study involved seven hundred (700) male soccer players, mean age 25.06 ± 4.41 years (range 18 to 35), divided in six age groups. Body composition was assessed according the anthropometric protocol by Matiegka, and relative muscle mass (MM%), bone (BM%) and fat (BF%) and absolute muscle mass (MMkg), bone (BMkg) and fat (BFkg) components were calculated. The Bruce protocol (incremental multistage treadmill test) was used for the estimation of maximal oxygen consumption.
Results: Mean values of body mass components for total sample were as follows: muscle mass (MM%)= 52.75 ± 2.63%, bone mass (BM%)=16.63 ± 1.29% and body fat (BF%)=14.12 ± 1.54%. Mean VO2max was 48.89±5.17 ml/kg/minute. Relative muscle mass (MM%) showed similar values across age different groups (ANOVA: F=2.174; p=0.06) while absolute muscle mass (MMkg) showed tendency of increment with age (ANOVA: F=2.136; p=0.01). Body fat (BFkg and BF%) was statistically higher in the older groups (ANOVA F=3.737; p<0.01; ANOVA F=4.117; p<0.01). Weak positive correlation between VO2 max and muscle component (r=0.243; p<0.001) and a weak negative correlation between VO2max and body fat (r=-0.08;p<0.05) were found.
Conclusions: Our results confirm the assumption that subjects with larger muscle mass have greater endurance and higher maximal oxygen consumption compared to subjects with larger body fat component.
