This study aimed to assess the enhancement of physical fitness and quality of life through an 8-week strength training program in male adolescent soccer players aged between 12 and 13 years. A lower body muscle group intervention was performed, with 17 players in the experimental group (EG) and 15 players in the control group (CG). The EG carried out soccer training complemented by specific strength work. Pre- and post- intervention assessments included body composition, jump height, speed with change of direction, maximum speed in 20 m, movement velocity in back-squat, perceived fatigue effort, academic performance, and quality of life. A general linear repeated measures model analysis was used considering each variable, the interaction between groups (EG, CG) and time (basal, 8-week), to analyze the differences between and within groups. The results showed a reduction in fat in the upper limbs and trunk, improvements in jump height, maximum speed of 20 m, and changes of direction, and increased quality of life ( < 0.05) in the EG. It was concluded that a strength program could improve some components of physical performance in male adolescent soccer players.
本研究旨在评估一项为期8周的力量训练计划对12至13岁男性青少年足球运动员身体素质和生活质量的提升效果。对下肢肌肉群进行了干预，实验组（EG）有17名运动员，对照组（CG）有15名运动员。实验组进行足球训练并辅以特定的力量训练。干预前后的评估包括身体成分、跳跃高度、变向速度、20米最大速度、后蹲运动速度、感知疲劳程度、学业成绩和生活质量。使用一般线性重复测量模型分析每个变量、组间（EG、CG）和时间（基础、8周）之间的相互作用，以分析组间和组内差异。结果显示，实验组上肢和躯干脂肪减少，跳跃高度、20米最大速度和变向能力得到改善，生活质量提高（P<0.05）。得出的结论是，力量训练计划可以改善男性青少年足球运动员的一些身体机能组成部分。
