In order to clarify whether leg-cooling after supramaximal treadmill exercise will change lactate disappearance rate from venous blood, blood lactate, calf blood flow, and skin temperature were determined in cold application and non-cold application recovery. In the cooling experiments, both legs were cooled with ice packs for 23 min during recovery. The skin temperature was significantly lower in the cold application as compared with the non-cold application. However, no significant difference was found in the blood lactate and/or calf blood flow between cold and non-cold conditions. In addition, there was no significant difference in the slope of regression line (blood lactate/blood flow) between cold and non-cold applications. These results suggest that no significant difference in the blood lactate between cold and non-cold applications could be explained by the lack of difference in the blood flow between cold and non-cold applications.
为了阐明力竭性跑步机运动后腿部冷却是否会改变静脉血中乳酸的消失速率，我们测定了冷应用恢复和非冷应用恢复过程中的血乳酸、小腿血流量和皮肤温度。在冷却实验中，恢复期间用冰袋对双腿冷却23分钟。与非冷应用相比，冷应用时皮肤温度显著降低。然而，冷应用和非冷应用条件下的血乳酸和/或小腿血流量没有显著差异。此外，冷应用和非冷应用之间回归线斜率（血乳酸/血流量）没有显著差异。这些结果表明，冷应用和非冷应用之间血乳酸无显著差异可由冷应用和非冷应用之间血流量缺乏差异来解释。
