摘要

背景/目标:虽然以往的证据表明,使用自由重量进行阻力训练是增强力量的一种更实用的方法,但在青少年皮划艇/独木舟运动员中,自由重量阻力训练的普及率相对较低。因此,本研究旨在评估自由重量阻力训练对青少年皮划艇/独木舟运动员身体成分和各种成绩因素的影响:27 名年轻的短跑皮划艇运动员(14 ± 1 岁;164 ± 7 厘米;56 ± 8 千克)完成了本研究。基线评估后,运动员被随机分为两个训练组:自由重量阻力训练组(FW)或对照组(C)。FW 组每周进行两次自由重量阻力训练,为期 24 周。C 组则在同一时间内保持常规的体重训练。所有参与者在训练前和训练后都进行了以下因变量的评估:身体成分、上半身力量、上半身等长肌力、等长大腿中部拉力、核心力量、反身跳、平衡、无氧能力和有氧表现:训练 24 周后,与对照组相比,自由重量阻力训练组的体重明显增加(从 56±5 千克增加到 58±4 千克,P<0.05),直腿抬高重复次数也有所提高(从 23±6 次增加到 26±4 次,P<0.05)。然而,两组在上半身等长肌力、力量、平衡和无氧/有氧表现方面没有明显差异:结论:对于阻力训练新手来说,24 周的训练时间可能是不够的。未来的研究应考虑在训练前加入动作适应期或学习阶段,从而提高自由重量阻力训练在增强力量方面的效果。

Free-Weight Resistance Training Enhances Core Muscle Strength but Does Not Translate to Improved Athletic Performance in Adolescent Canoe/Kayak Athletes.

Background/objectives: While previous evidence has shown that using free weights for resistance training is a more practical approach to enhancing strength, there is a relatively low prevalence of free-weight resistance training among adolescent kayak/canoe athletes. Therefore, this study aims to assess the impact of free-weight resistance training on body composition and various performance factors among adolescent canoe/kayak athletes.

Methods: Twenty-seven young sprint kayakers and canoeists (14 ± 1 years; 164 ± 7 cm; 56 ± 8 kg) completed this study. Following baseline assessments, athletes were randomly divided into two training groups: the free-weight resistance training group (FW) or the control group (C). The FW group underwent free-weight resistance training sessions twice weekly for 24 weeks. The C group maintained their regular bodyweight training sessions during the same timeframe. All participants performed both the pre- and post-training assessments for the following dependent variables: body composition, upper-body power, upper-body isometric muscle strength, isometric mid-thigh pull, core strength, countermovement jump, balance, anaerobic ability, and aerobic performance.

Results: After 24 weeks of training, the free-weight resistance training group exhibited a significant increase in body weight (from 56 ± 5 kg to 58 ± 4 kg, p < 0.05) and improvements in the number of straight leg raise repetitions (from 23 ± 6 to 26 ± 4, p < 0.05) compared to the control group. However, the two groups observed no significant differences between upper-body isometric muscle strength, power, balance, and anaerobic/aerobic performance.

Conclusions: A 24-week training duration might be insufficient for novice participants in resistance training. Future research should consider incorporating an adaptation period or a learning phase for movements before training, thereby enhancing the efficacy of free-weight resistance training in increasing strength.

期刊介绍: Children is an international, open access journal dedicated to a streamlined, yet scientifically rigorous, dissemination of peer-reviewed science related to childhood health and disease in developed and developing countries. The publication focuses on sharing clinical, epidemiological and translational science relevant to children’s health. Moreover, the primary goals of the publication are to highlight under‑represented pediatric disciplines, to emphasize interdisciplinary research and to disseminate advances in knowledge in global child health. In addition to original research, the journal publishes expert editorials and commentaries, clinical case reports, and insightful communications reflecting the latest developments in pediatric medicine. By publishing meritorious articles as soon as the editorial review process is completed, rather than at predefined intervals, Children also permits rapid open access sharing of new information, allowing us to reach the broadest audience in the most expedient fashion.
