RESEARCH ON THE MAIN METHODS OF CORE STRENGTH TRAINING IN SPRINTERS

ABSTRACT Introduction With the development of increasingly competitive sports, coaches began experimenting with new methods for training athletes. Although among the most explored training methods is core strength training, a set of muscle groups that stabilize the trunk and hips, there are few studies on the effectiveness of this training dedicated to sprinters. Objective This paper investigates the training method of sprinters based on core strength training, studying the method and its influence on athletes’ performance. Methods Sixteen athletes with similar technical levels and physical fitness were selected, and professional coaches were invited to test the training samples. The athletes were randomly assigned to the experimental and control group (8 in each). The experimental group received core strength training for eight weeks, while the control group received general training. Results Off-core training affected the ankle joint angle of the support leg and the ankle joint angle of the swing leg (P < 0.01). After eight weeks of training, the performance of both groups improved without considerable differences. The high jump results of the athletes in the experimental group also improved compared to the previous training. Conclusion The physical function of athletes can be improved through core strength training to improve the sprinters’ competitive level and technical ability. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

摘要
引言 随着竞技体育竞争日趋激烈，教练员们开始尝试全新的运动员训练方法。尽管核心力量训练（core strength training）——用于稳定躯干与髋关节的肌群训练——是目前探索最为深入的训练方法之一，但针对短跑运动员的专项核心力量训练有效性研究仍较为匮乏。
研究目的 本文针对短跑运动员的核心力量训练方法展开研究，探讨该训练方式及其对运动员竞技表现的影响。
研究方法 选取16名技术水平与身体素质相近的短跑运动员，邀请专业教练员对训练样本进行测评。将运动员随机分为实验组与对照组，每组各8人。实验组接受为期8周的核心力量训练，对照组则开展常规通用训练。
研究结果 核心力量训练对支撑腿踝关节角度与摆动腿踝关节角度均产生显著影响（P<0.01）。经过8周训练后，两组运动员的竞技表现均有所提升，但组间差异无统计学意义。此外，实验组运动员的跳高成绩相较训练前亦有所改善。
研究结论 核心力量训练可有效改善运动员的身体机能，进而提升短跑运动员的竞技水平与专项技术能力。
