摘要

目的。本研究评估了三个年龄组足球运动员的等距扭矩、腘绳肌与股四头肌的比率和跳跃表现。方法:67名男性运动员按年龄分为17岁以下组(U17: n = 29)、20岁以下组(U20: n = 22)和20岁以上组(PRO: n = 16)。他们进行了反动作(CMJ)和蹲跳(SJ)。此外,还评估了膝关节屈伸时右(R-TOR)和左肢体(L-TOR)扭矩的最大等距收缩。测定腘绳肌-股四头肌(H:Q)和CMJ:SJ比值。结果。与U17和U20相比,PRO具有更高的CMJ(分别为20%和14%);p < 0.01)和SJ(分别为19%和13%;p < 0.01和p = 0.02),膝关节伸展时绝对R-TOR和L-TOR较高(分别为40%和58%;p < 0.01)。PRO在膝关节屈曲时的绝对L-TOR和R-TOR高于U17(分别为22%和26%);P = 0.04和P < 0.01)。除膝关节伸展R-TOR (PRO > U17;P = 0.04)。在PRO和U17之间,腘绳肌绝对扭矩(效应值:0.30-0.92)的差异更大(效应值:1.37-1.46)。任何H:Q扭矩比均未发现差异,但PRO组与其他组之间的效应大小适中(0.71-0.75)。CMJ:SJ比值无差异。结论。职业选手比U17和U20选手更强大。PRO和U17/U20之间的力量水平差异取决于肌肉。股四头肌比腘绳肌更大的力量发展可以导致PRO更低的等距H:Q扭矩比。

Isometric knee torque, quadriceps-hamstrings ratio, and jumping parameters in Brazilian soccer players of different age categories
Purpose. This study assessed the isometric torque, hamstring-to-quadriceps ratio, and jump performance among three age groups of soccer players. Methods. 67 male players were divided by chronological age into the under-17 (U17: n = 29), under-20 (U20: n = 22), and above-20-year (PRO: n = 16) groups. They performed countermovement (CMJ) and squat (SJ) jumps. Also, maximal isometric contractions during knee flexion and extension for right (R-TOR) and left limb (L-TOR) torque were assessed. Hamstrings-quadriceps (H:Q) and CMJ:SJ ratios were determined. Results. Compared with U17 and U20, PRO showed higher CMJ ( = 20% and 14%; both p < 0.01) and SJ ( = 19% and 13%; p < 0.01 and p = 0.02, respectively), and higher absolute R-TOR and L-TOR during knee extension ( = 40% and 58%; both p < 0.01). PRO exhibited higher absolute L-TOR and R-TOR during knee flexion than U17 ( = 22% and 26%; p = 0.04 and p < 0.01, respectively). Between-group differences were not detected in normalized torque, except for knee extension R-TOR (PRO > U17; p = 0.04). Greater differences for quadriceps absolute torque (effect size: 1.37–1.46) were observed in the hamstrings (effect size: 0.30–0.92) between PRO and U17. No differences were found for any H:Q torque ratio, but moderate effect sizes (0.71–0.75) were verified between PRO and the other groups. No differences were found for CMJ:SJ ratio. Conclusions. PRO players are more powerful than U17 and U20. Differences in strength level between PRO and U17/U20 are muscle-dependent. The larger strength development of quadriceps over hamstrings can result in lower isometric H:Q torque ratio for PRO.
