This study aimed to evaluate the effects of warm-up intensity on energetic contribution and performance during a 100-m sprint. Ten young male sprinters performed 100-m sprints following both a high-intensity warm-up (HIW) and a low-intensity warm-up (LIW). Both the HIW and LIW were included in common baseline warm-ups and interventional warm-ups (eight 60-m runs, HIW; 60 to 95%, LIW; 40% alone). Blood lactate concentration [La], time trial, and oxygen uptake (VO) were measured. The different energy system contribution was calculated by using physiological variables. [La] following HIW was significantly higher than in LIW (11.86 ± 2.52 vs. 9.24 ± 1.61 mmol·L; < 0.01, respectively). The 100-m sprint time trial was not significantly different between HIW and LIW (11.83 ± 0.57 vs. 12.10 ± 0.63 s; > 0.05, respectively). The relative (%) phosphagen system contribution was higher in the HIW compared to the LIW (70 vs. 61%; < 0.01, respectively). These results indicate that an HIW increases phosphagen and glycolytic system contributions as compared to an LIW for the 100-m sprint. Furthermore, an HIW prior to short-term intense exercise has no effect on a 100-m sprint time trial; however, it tends to improve times (decreased 100-m time trial; -0.27 s in HIW vs. LIW).
本研究旨在评估热身强度对100米短跑过程中能量贡献和成绩的影响。十名年轻男性短跑运动员在进行高强度热身（HIW）和低强度热身（LIW）后分别进行100米短跑。HIW和LIW均包含在常见的基础热身和干预性热身中（八次60米跑，HIW；60%至95%，LIW；仅40%）。测量血乳酸浓度[La]、计时赛成绩和摄氧量（VO）。通过使用生理变量计算不同能量系统的贡献。HIW后的[La]显著高于LIW（分别为11.86±2.52与9.24±1.61 mmol·L；<0.01）。HIW和LIW之间的100米短跑计时赛成绩无显著差异（分别为11.83±0.57与12.10±0.63秒；>0.05）。与LIW相比，HIW中磷酸原系统的相对（%）贡献更高（分别为70%与61%；<0.01）。这些结果表明，与LIW相比，HIW会增加100米短跑中磷酸原和糖酵解系统的贡献。此外，短期剧烈运动前的HIW对100米短跑计时赛成绩没有影响；然而，它往往会提高成绩（100米计时赛成绩下降；HIW比LIW快-0.27秒）。
