The purpose of this study was to determine whether a dynamic-stretching warm-up (DWU) intervention performed daily over 4 weeks positively influenced power, speed, agility, endurance, flexibility, and strength performance measures in collegiate wrestlers when compared to a static-stretching warm-up (SWU) intervention. Twenty-four male National Collegiate Athletic Association Division I wrestlers were randomly assigned to complete either a 4-week treatment condition (DWU) (n = 11) or an active control condition (SWU) (n = 13) prior to their daily preseason practices. Anthropometric and performance measures were conducted before and after the 4-week experimental period (i.e., DWU or SWU). Measures included peak torque of the quadriceps and hamstrings, medicine ball underhand throw, 300-yd shuttle, pull-ups, push-ups, sit-ups, broad jump, 600-m run, sit-and-reach test, and trunk extension test. Wrestlers completing the 4-week DWU intervention had several performance improvements, including increases in quadriceps peak torque (11%), broad jump (4%), underhand medicine ball throw (4%), sit-ups (11%), and push-ups (3%). A decrease in the average time to completion of the 300-yd shuttle (-2%) and the 600-m run (-2.4%) was suggestive of enhanced muscular strength, endurance, agility, and anaerobic capacity in the DWU group. In contrast to the DWU intervention, there was no observed improvement in the SWU group for peak torque of the quadriceps, broad jump, 300-yd shuttle run, medicine ball underhand throw for distance, sit-ups, push-ups, or 600-m run, and decrements in some performance measures occurred. The findings suggest that incorporation of this specific 4-week DWU intervention into the daily preseason training regimen of wrestlers produced longer-term or sustained power, strength, muscular endurance, anaerobic capacity, and agility performance enhancements.
本研究的目的是确定与静态拉伸热身（SWU）干预相比，在4周内每天进行的动态拉伸热身（DWU）干预是否对大学生摔跤运动员的力量、速度、敏捷性、耐力、柔韧性和力量表现指标产生积极影响。24名美国国家大学体育协会一级男子摔跤运动员在每日季前训练前被随机分配，以完成为期4周的治疗条件（DWU）（n = 11）或积极对照条件（SWU）（n = 13）。在为期4周的实验期（即DWU或SWU）前后进行人体测量和表现指标测试。测量指标包括股四头肌和腘绳肌的峰值扭矩、实心球下手投掷、300码穿梭跑、引体向上、俯卧撑、仰卧起坐、立定跳远、600米跑、坐位体前屈测试和躯干伸展测试。完成4周DWU干预的摔跤运动员在多项表现上有所改善，包括股四头肌峰值扭矩增加（11%）、立定跳远增加（4%）、实心球下手投掷增加（4%）、仰卧起坐增加（11%）和俯卧撑增加（3%）。300码穿梭跑（-2%）和600米跑（-2.4%）完成平均时间的减少表明DWU组的肌肉力量、耐力、敏捷性和无氧能力有所增强。与DWU干预相反，SWU组在股四头肌峰值扭矩、立定跳远、300码穿梭跑、实心球下手投掷距离、仰卧起坐、俯卧撑或600米跑方面没有观察到改善，并且一些表现指标出现了下降。研究结果表明，将这种特定的4周DWU干预纳入摔跤运动员的每日季前训练方案中，可产生长期或持续的力量、力量、肌肉耐力、无氧能力和敏捷性表现提升。
