The objective was to investigate the effects of a 9-week elastic resistance band training within the regular handball training sessions compared to regular handball training only. Participants were randomly assigned to an intervention (INT: n=16; age: 17.0 ± 0.7 years) or a control (CON: n=16; age: 16.9 ± 0.9 years) group. The INT-group performed elastic resistance band exercises (3/week) for 20-30 minutes while the CON-group conducted regular handball training only. Pre- and post-training assessments included measures of strength endurance (Closed Kinetic Chain Upper Extremity Stability Test [CKCUEST]), maximal isometric strength (MIS), and throwing velocity. Significant main effects of Test (i.e. pre- to post-training enhancements) were detected for the CKCUEST (p < 0.001, 0.54 ≤ η ≤ 0.57) and throwing velocity (p = 0.001, η = 0.34). We found a significant (throwing velocity: p = 0.004, η = 0.25) and a tendency toward (MIS of the internal rotators, non-throwing arm: p = 0.068, η = 0.12) a significant Test × Group interaction, both in favour of the INT-group. A 9-week strengthening program using elastic resistance bands combined with regular handball training is effective to improve upper extremity strength endurance, throwing velocity, and MIS of the internal rotators of the non-throwing arm.
目的是研究在常规手球训练课程中进行为期9周的弹力带训练与仅进行常规手球训练相比的效果。参与者被随机分配到干预组（INT：n = 16；年龄：17.0±0.7岁）或对照组（CON：n = 16；年龄：16.9±0.9岁）。干预组每周进行3次弹力带练习，每次20 - 30分钟，而对照组仅进行常规手球训练。训练前和训练后的评估包括力量耐力测量（闭链上肢稳定性测试[CKCUEST]）、最大等长肌力（MIS）和投掷速度。在CKCUEST（p < 0.001，0.54≤η≤0.57）和投掷速度（p = 0.001，η = 0.34）方面检测到测试（即训练前到训练后的增强）的显著主效应。我们发现存在显著的（投掷速度：p = 0.004，η = 0.25）以及一种趋势（非投掷手臂内旋肌的MIS：p = 0.068，η = 0.12），即显著的测试×组交互作用，两者均有利于干预组。一项为期9周的使用弹力带并结合常规手球训练的强化计划对于提高上肢力量耐力、投掷速度以及非投掷手臂内旋肌的MIS是有效的。
