Maturity status varies among adolescents of the same age, making age an unreliable indicator. Although maturity status affects movement patterns, differences in landing force and jump performance among maturity groups remain unclear.
HYPOTHESIS/PURPOSE: This study compared landing force and jump performance during drop vertical jump in adolescent male soccer players based on classifications by maturity status and age. A hypothesis was formulated that landing force would be greater during the period of peak height velocity (PHV) and jump performance higher in the post-PHV group, showing clearer differences than age.
Cross-sectional study.
Forty-five male soccer players (13.5 ± 0.9 years) were grouped by maturity status (pre-, circa-, and post-PHV), and by age. Landing forces (peak vertical ground reaction force [PVGRF], time to PVGRF, and loading rate) and jump performance (jump height, contact time, reactive strength index [RSI], PVGRF, and power) were measured using a force plate. A one-way analysis of variance was performed to detect group differences.
Landing forces showed no significant differences among maturity groups (PVGRF: = 0.190; time to PVGRF: = 0.122; and loading rate: = 0.255). Jump height was greater in post-PHV (32.87 ± 4.18 cm) than in pre-PHV (25.17 ± 4.85 cm, = 0.001). RSI was higher in post- (1.33 ± 0.31 m/s) than in pre- (1.00 ± 0.29 m/s, = 0.024) and circa-PHV groups (1.02 ± 0.23 m/s, = 0.021). Power was greater in post- (40.40 ± 6.31 W/kg) than in pre- (33.15 ± 7.78 W/kg, = 0.045) and circa-PHV groups (33.59 ± 5.50 W/kg, = 0.037). Age-related differences were found only in jump height ( < 0.001).
Maturity status classification detected significant group differences in jump height, RSI, and power, but age classification only detected a significant group difference in jump height.
同一年龄段的青少年成熟状态各不相同，这使得年龄成为一个不可靠的指标。尽管成熟状态会影响运动模式，但不同成熟度组之间在着地力和跳跃表现上的差异仍不明确。
假设/目的：本研究基于成熟状态和年龄分类，比较青少年男性足球运动员在纵跳下落过程中的着地力和跳跃表现。提出的假设是，在身高增长高峰期（PHV）期间着地力会更大，且在PHV之后的组中跳跃表现更高，与年龄相比差异更明显。
横断面研究。
45名男性足球运动员（13.5±0.9岁）按成熟状态（PHV之前、接近PHV、PHV之后）和年龄进行分组。使用测力台测量着地力（垂直地面反作用力峰值[PVGRF]、达到PVGRF的时间和加载速率）和跳跃表现（跳跃高度、接触时间、反应强度指数[RSI]、PVGRF和功率）。进行单因素方差分析以检测组间差异。
成熟度组之间着地力无显著差异（PVGRF： = 0.190；达到PVGRF的时间： = 0.122；加载速率： = 0.255）。PHV之后组的跳跃高度（32.87±4.18厘米）高于PHV之前组（25.17±4.85厘米， = 0.001）。RSI在PHV之后组（1.33±0.31米/秒）高于PHV之前组（1.00±0.29米/秒， = 0.024）和接近PHV组（1.02±0.23米/秒， = 0.021）。功率在PHV之后组（40.40±6.31瓦/千克）高于PHV之前组（33.15±7.78瓦/千克， = 0.045）和接近PHV组（33.59±5.50瓦/千克， = 0.037）。仅在跳跃高度方面发现了与年龄相关的差异（ < 0.001）。
成熟状态分类在跳跃高度、RSI和功率方面检测到显著的组间差异，但年龄分类仅在跳跃高度方面检测到显著的组间差异。
