Track and Field athletes perform different types of warm-ups at varying levels of volume and/or intensity prior to competition. Theoretically, this prepares sport specific muscles for activity by increasing muscle temperature, thus mitigating the chance for injury. There is a paucity of information regarding the optimum level for warm-ups regarding maximizing performance in middle distance events. The aim of this study was to examine the effects of three different warm-ups on 800-meter performance. Thirteen Division I student-athletes (seven males and six females) from the Southeastern Conference (SEC) who were middle distance runners participated in this study. We utilized a randomized, cross-over study design to test low, medium, and high-volume warm-up protocols on 800-meter performance. Trials were conducted over a span of three weeks on a SEC University outdoor track. We used a 2 (Sex) x 3 (Warm-Up Protocol) mixed-factor ANOVA, and our results show a main effect of warm-up volume that is not moderated by sex. Post-hoc tests reveal a high-volume warm-up yields superior results for the 800-meter run in comparison to a medium volume warm-up, which provides better results than a low-volume warm-up. These findings may be of value in providing information in program design for coaches on the most effective warm-up protocols for 800-meter runners. Identifying the best warm-up protocol to prime an 800-meter runner for peak performance may not only assist in preventing injury, but enhance performance thus leading to an increased of achievement, and confidence in personal ability.
田径运动员在比赛前会进行不同类型、不同量和/或强度的热身活动。从理论上讲，这通过提高肌肉温度让特定运动的肌肉为活动做好准备，从而降低受伤几率。关于中距离项目热身的最佳水平以实现最佳成绩的相关信息匮乏。本研究的目的是检验三种不同热身活动对800米跑成绩的影响。来自东南联盟（SEC）的13名一级联盟学生运动员（7名男性和6名女性）中距离跑选手参与了本研究。我们采用随机交叉研究设计来测试低、中、高量热身方案对800米跑成绩的影响。试验在SEC大学的室外跑道上进行，为期三周。我们使用2（性别）×3（热身方案）混合因素方差分析，结果显示热身量的主效应不受性别的影响。事后检验表明，与中等量热身相比，大量热身对800米跑成绩有更好的效果，中等量热身比小量热身效果更好。这些发现可能有助于为教练提供800米跑运动员最有效热身方案的项目设计信息。确定最佳热身方案以使800米跑运动员达到最佳表现，不仅有助于预防受伤，还能提高成绩，从而增强成就感和个人能力信心。
