ABSTRACT
OBJECTIVES:
Examine the effects of maturation on single leg jumping performance in elite male youth soccer players.DESIGN:
Cross sectional.SETTING:
Academy soccer clubs.PARTICIPANTS:
347 male youth players classified as either pre, circa or post-peak height velocity (PHV). MAIN OUTCOMEMEASURES:
Single leg countermovement jump (SLCMJ) height, peak vertical landing forces (pVGRF), knee valgus and trunk side flexion.RESULTS:
Vertical jump height and absolute pVGRF increased with each stage of maturation (pâ¯<â¯0.001; dâ¯=â¯0.85-2.35). Relative to body weight, significantly higher landing forces were recorded on the left leg in circa versus post-PHV players (pâ¯<â¯0.05; dâ¯=â¯-0.40). Knee valgus reduced with maturation but the only notable between-group differences were shown in post-PHV players (pâ¯<â¯0.05; dâ¯=â¯0.67); however, greater ipsilateral lateral trunk flexion angles was also present and these differences were significantly increased relative to circa-PHV players (pâ¯<â¯0.05; dâ¯=â¯0.85).CONCLUSION:
Periods of rapid growth are associated with landing kinetics which may heighten injury risk. While reductions in knee valgus were displayed with maturation; a compensatory strategy of greater trunk lateral flexion was evident in post-PHV players and this may increase the risk of injury.
