Abstract:
UNASSIGNED: This study investigates the efficacy of training methodologies aimed at mitigating asymmetries in lower limb strength and explosiveness among basketball players.
UNASSIGNED: Thirty male university basketball athletes were enrolled in this research. Initial assessments were made regarding their physical attributes, strength, and explosiveness. Subsequently, the participants were randomly allocated into two groups: an experimental group (EG, n = 15) and a control group (CG, n = 15). Over 10 weeks, the EG engaged in a unilateral compound training regimen, incorporating resistance training exercises such as split squats, Bulgarian split squats, box step-ups, and single-leg calf raises (non-dominant leg: three sets of six repetitions; dominant leg: one set of six repetitions) and plyometric drills including lunge jumps, single-leg hops with back foot raise, single-leg lateral jumps, and single-leg continuous hopping (non-dominant leg: three sets of 12 repetitions; dominant leg: one set of 12 repetitions). The CG continued with their standard training routine. Assessments of limb asymmetry and athletic performance were conducted before and after the intervention to evaluate changes.
UNASSIGNED: 1) Body morphology assessments showed limb length and circumference discrepancies of less than 3 cm. The initial average asymmetry percentages in the single-leg countermovement jump (SLCMJ) for jump height, power, and impulse were 15.56%, 12.4%, and 4.48%, respectively. 2) Post-intervention, the EG demonstrated a significant reduction in the asymmetry percentages of SLCMJ height and power (p < 0.01), along with improvements in the isometric mid-thigh pull (IMTP) test metrics (p < 0.05). 3) The EG also showed marked enhancements in the double-leg countermovement jump (CMJ) and standing long jump (SLJ) outcomes compared to the CG (p < 0.01), as well as in squat performance (p < 0.05).
UNASSIGNED: The 10-week unilateral compound training program effectively reduced the asymmetry in lower limb strength and explosiveness among elite male university basketball players, contributing to increased maximal strength and explosiveness.
摘要:
本研究调查了旨在减轻篮球运动员下肢力量和爆发性不对称的训练方法的功效。
30名大学男子篮球运动员参加了这项研究。对它们的物理属性进行了初步评估,力量,和爆发力。随后,参与者被随机分为两组:实验组(EG,n=15)和对照组(CG,n=15)。超过10周,EG从事单方面复合训练方案,结合阻力训练练习,如分裂深蹲,保加利亚分裂深蹲,箱步进,单腿小腿抬高(非优势腿:三组共六次重复;优势腿:一组共六次重复)和包括弓步跳跃在内的力量训练,单腿跳跃,后脚抬高,单腿横向跳跃,和单腿连续跳跃(非优势腿:三组12次重复;优势腿:一组12次重复)。CG继续他们的标准训练程序。在干预前后进行肢体不对称性和运动表现的评估,以评估变化。
1)身体形态评估显示肢体长度和周长差异小于3厘米。单腿反运动跳跃(SLCMJ)中跳跃高度的初始平均不对称百分比,电源,冲动是15.56%,12.4%,和4.48%,分别。2)干预后,EG显示SLCMJ高度和功率的不对称百分比显着降低(p<0.01),随着等距大腿中拉力(IMTP)测试指标的改善(p<0.05)。3)与CG相比,EG还显示出双腿反运动跳跃(CMJ)和立定跳远(SLJ)结果的显着增强(p<0.01),以及深蹲性能(p<0.05)。
为期10周的单边复合训练计划有效降低了精英大学男篮运动员下肢力量和爆发力的不对称性,有助于增加最大强度和爆发力。
