Stretching before anaerobic events has resulted in declines in performance; however, the immediate effects of stretching on endurance performance have not been investigated. This study investigated the effects of static stretching on energy cost and endurance performance in trained male runners. Ten trained male distance runners aged 25 +/- 7 years with an average VO2max of 63.8 +/- 2.8 ml/kg/min were recruited. Participants reported to the laboratory on 3 separate days. On day 1, anthropometrics and VO2max were measured. On days 2 and 3, participants performed a 60-minute treadmill run randomly under stretching or nonstretching conditions separated by at least 1 week. Stretching consisted of 16 minutes of static stretching using 5 exercises for the major lower body muscle groups, whereas nonstretching consisted of 16 minutes of quiet sitting. The run consisted of a 30-minute 65% VO2max preload followed by a 30-minute performance run where participants ran as far as possible without viewing distance or speed. Total calories expended were determined for the 30-minute preload run, whereas performance was measured as distance covered in the performance run. Performance was significantly greater in the nonstretching (6.0 +/- 1.1 km) vs. the stretching (5.8 +/- 1.0 km) condition (p < 0.05), with significantly greater energy expenditure during the stretching compared with the nonstretching condition (425 +/- 50 vs. 405 +/- 50 kcals). Our findings suggest that stretching before an endurance event may lower endurance performance and increase the energy cost of running.
在进行无氧运动之前进行伸展运动可能会导致运动表现下降；然而，伸展运动对耐力表现的即时影响尚未得到研究。本研究调查了静态伸展对训练有素的男性跑步者的能量消耗和耐力表现的影响。招募了 10 名年龄为 25 +/- 7 岁、平均 VO2max 为 63.8 +/- 2.8 ml/kg/min 的训练有素的男性长跑运动员。参与者在 3 天内分别向实验室报到。第 1 天测量了人体测量学和 VO2max。第 2 天和第 3 天，参与者在伸展或非伸展条件下随机进行 60 分钟的跑步机跑步，至少相隔 1 周。伸展运动包括使用 5 种主要下半身肌肉群的静态伸展 16 分钟，而非伸展运动包括安静坐 16 分钟。跑步包括 30 分钟 65%VO2max 的预负荷，然后是 30 分钟的性能跑，在此期间，参与者尽可能远地跑步，而不观看距离或速度。确定 30 分钟预负荷跑的总卡路里消耗，而性能则以性能跑中覆盖的距离来衡量。在非伸展（6.0 +/- 1.1 公里）与伸展（5.8 +/- 1.0 公里）条件下，性能明显更好（p < 0.05），伸展期间的能量消耗明显高于非伸展条件（425 +/- 50 与 405 +/- 50 卡路里）。我们的研究结果表明，在耐力运动前进行伸展运动可能会降低耐力表现并增加跑步的能量消耗。
