Anthropometric and physical fitness characteristics of male South African youth soccer players.

Background: This study comparatively investigates the anthropometric and physical fitness characteristics of male South African players by age group, competitive level and playing position.

Methods: The sample consisted of 201 youth soccer players drawn from six sports academies in South Africa. Players were subjected to standardized protocols for anthropometric measurements (stature, body mass and body fat percentage) and physical fitness tests (flexibility, vertical jump, push-ups, sit-ups, muscle strength, agility, 30-m sprint and V̇O2max). A series of two-way analyses of variance was performed to determine the interactions between playing position (goalkeeper, defender, midfielder or attacker) or age group (13, under-15, under-17 or under-19) and competitive level (elite or non-elite).

Results: The results show significant interaction effects of agility, body fat percentage and sprint speed between the players' competitive levels and age group (P<0.05). No interaction effect was found between playing position and competitive level in any anthropometric or physical fitness variable (P>0.05). However, playing position exhibited significant main effects in the youth players' aerobic endurance and body mass (P<0.05).

Conclusions: The results provide practical implications for tailoring position-specific conditioning regimes that optimize effective soccer performance.
