摘要

文献表明,膝关节损伤是篮球运动员中最常见的损伤。膝关节周围的优势/非优势和前后强度比用于评估强度平衡。但是,关于职业水平篮球力量评估的研究却少得多。本研究的目的是:(i)比较专业水平篮球运动员在不同角速度下同心膝关节伸展和屈曲过程中腘绳肌和股四头肌的力量值,(ii)确定这些收缩过程中的优势和非优势力量值。13名职业男子篮球运动员自愿参与了本研究。用等速测功机在240-180-120-600/s的角速度下评估腿部力量。计算腘绳肌和股四头肌单侧峰值扭矩比(H/Q)和优势-非优势力量比。对双侧和单侧强度输出进行独立t检验。在所有角速度下,峰值扭矩、归一化峰值扭矩和H/Q下的主导强度值和非主导强度值之间没有统计学上的显著差异。在所有角速度下,两条腿的相对峰值扭矩输出相似。此外,所有速度下的H/Q均计算为≥0.60。这项研究的结果表明,对职业篮球运动员的单侧和双侧评价没有任何显著差异。这些不显著的差异可能与保持双腿力量相似的必要性有关。

COMPARISON OF DOMINANT AND NONDOMINANT LEG STRENGTH AND HAMSTRING: QUADRICEPS RATIO IN PROFESSIONAL BASKETBALL PLAYERS
The literature has revealed that knee injuries are the most common injury among basketball players. The strength ratios dominant/non-dominant and posterior-anterior around the knee joint are used to evaluate strength balances. But there has been far less research published about strength evaluation in professional-level basketball. The objectives of the present study were: (i) to compare hamstring and quadriceps muscles’ strength values during concentric knee extension and flexion at different angular velocities at professional level basketballers, (ii) to determine dominant and non-dominant strength values during these contractions. 13 professional male basketball athletes voluntarily participated in the study. The leg strength was evaluated with an isokinetic dynamometer at 240- 180-120-600 /s angular velocities. The hamstring and quadriceps unilateral peak torque ratio (H/Q) and dominant non-dominant strength ratio were calculated. The independent t-test was computed to bilateral and unilateral strength outputs. There was no statistically significant difference between dominant and non-dominant strength values at peak torque, normalized peak torque, and H/Q at all angular velocities. Relative peak torque outputs in both legs were similar at all angular velocities. Also, the H/Q was calculated as ≥0.60 in all velocities. The results of this study suggest there were not any significant differences in the unilateral and bilateral evaluations of professional basketballers. These nonsignificant differences could be related to the necessity to maintain similar strength of two legs.
