INFLUENCE OF UPPER BODY STRETCHING EXERCISES ON SHOT PUT

ABSTRACT Introduction The technique in the shot put and the ability in the throwing stage are two important factors that determine the ability of athletes. Qualified experts and coaches attach great importance to training and research on the ability of the throwing stage and the ability to throw. Objective Compare gravity load training and single incremental load training through practical means, analyzing the impacts on throwing ability in athletes. Methods The self-assessment method was used to conduct the comparative experiment on different forms of strength training in 20 college students. The experimental scheme adopts the single incremental load strength training, and the control scheme adopts the traditional barbell training. Results : After the experiment, the hand angle of group I was significantly higher than that of group II (P &lt; 0.05); after the experiment, the shoulder angle of group I was significantly higher than that of group II (P &lt; 0.05); after the experiment, the performance of the seated shot placed in group I was significantly higher than that of group II (P &lt; 0.05), and there was no significant difference in the standing performance (P &gt; 0.05). Conclusion Single incremental load training can significantly improve the throwing ability of shot put athletes. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.摘要 引言：铅球技术与投掷阶段能力是决定运动员竞技能力的两大关键因素。专业专家与教练员均高度重视投掷阶段能力与投掷表现的训练及研究。研究目的：通过实践手段对比重力负荷训练与单一递增负荷训练对运动员投掷能力的影响。研究方法：选取20名大学生受试者，采用自评法开展不同形式力量训练的对比实验。实验组采用单一递增负荷力量训练方案，对照组采用传统杠铃训练方案。结果：实验结束后，实验组（I组）手部角度显著高于对照组（II组）（P < 0.05）；实验结束后，实验组肩部角度显著高于对照组（P < 0.05）；实验结束后，实验组坐姿铅球投掷成绩显著高于对照组（P < 0.05），而站姿投掷成绩无显著差异（P > 0.05）。结论：单一递增负荷训练可显著提升铅球运动员的投掷能力。证据等级：II级；治疗性研究——治疗效果探究。
