Professional soccer players from the first team (1st team, n=27), under twenty-one (U21, n=21) and under eighteen (U18, n=35) squads of an English Premier League soccer team were assessed for whole body and regional estimates of body composition using dual-energy X-ray absorptiometry (DXA). Per cent body fat was lower in 1st team (10.0 +/- 1.6) compared with both U21 (11.6 +/- 2.5, P=0.02) and U18 (11.4 +/- 2.6, P=0.01) players. However, this difference was not due to variations (P=0.23) in fat mass between squads (7.8 +/- 1.6v 8.8 +/- 2.1v 8.2 +/- 2.4kg, respectively) but rather the presence of more lean mass in 1st team (66.9 +/- 7.1kg, P<0.01) and U21 (64.6 +/- 6.5kg, P=0.02) compared with U18 (60.6 +/- 6.3kg) players. Accordingly, fat mass index was not different (P=0.138) between squads, whereas lean mass index was greater (P<0.01) in 1st team players (20.0 +/- 1.1kg center dot m(-2)) compared with U18 players (18.8 +/- 1.4kg center dot m(-2)). Differences in lean mass were also reflective of higher lean tissue mass in all regions, for example, upper limbs/lower limbs and trunk. Data suggest that training and nutritional interventions for younger players should therefore be targeted to lean mass growth as opposed to body fat loss.
