| 摘 要： | 目的: 观察下肢间歇负压疗法对男子赛艇运动员股四头肌皮肤微循环血流灌注量的影响,为该方法的实际应用提供理论依据。方法: 选取国家赛艇集训队的14名男子运动员,随机分为试验组和对照组,两组队员每日的训练计划相同,采用德国生产的VACUSPORT间歇负压体能恢复舱对试验组队员实行恢复干预,每次干预20 min,每周干预5次,共持续4周。在4周干预前后利用PeriFlux System 5000激光多普勒血流监测仪采集两组运动员股四头肌皮肤微循环血流灌注量(MBP)、血细胞运动速度(AVBC)及血细胞浓度(CMBC)等数据,测试值包括基础值与加热后值(44℃),并以加热前后的差值作为该指标的储备能力。结果: 干预前两组的微循环相关指标无统计学差异(P＞0.05),4周干预后的测试结果如下①MBP:试验组MBP的加热后值和前后差值均显著高于对照组(P＜0.05);组内比较无统计学差异。②AVBC:试验组AVBC的加热后值和前后差值均显著低于对照组(P＜0.05);组内比较发现,干预后试验组AVBC的加热后值相比干预前显著降低(P＜0.01),其加热前后差值相比干预前显著降低(P＜0.05)。③CMBC:试验组CMBC的加热后值和前后差值均非常显著高于对照组(P＜0.01);组内比较无统计学差异。结论: 下肢间歇负压疗法可改善男子赛艇运动员股四头肌皮肤微循环血流状态,对促进体能的快速恢复有着积极作用。

| Abstract: | Objective: To investigate the effects of intermittent negative pressure therapy on the skin microcirculation perfusion of quadriceps in male rowers, and to provide basis for the practical application of this method. Methods: Fourteen male rowers were selected from the national rowing team and randomly divided into experimental and control groups. The daily training plans of two groups were the same. The recovery intervention for experimental group was implemented by 20 minutes in the cube of Vacusport Regeneration System (German), 5 times per week for 4 weeks, no recovery intervention for control group. Microcirculation markers were collected by PeriFlux5000 system before and after the 4-week intervention. The markers included microcirculatory blood perfusion(MBP), average velocity of blood cells(AVBC), concentration of moving blood cells (CMBC), and values of the markers included basic values and post-heating values (44℃), difference before and after heating of the values was considered as the reserve capacity of those markers. Results: The test results before the 4 weeks intervention showed there was no statistical difference between the two groups(P＞0.05). After the 4 weeks intervention: ①MBP: The post-heating value and the difference of the experimental group were significantly higher than those of the control group (P＜0.05). But there was no statistical inner-group difference. ②AVBC: The post-heating values and the difference in the experimental group were significantly lower than those in the control group (P＜0.05). Intra-group comparison found that the post-heating values after post-intervention were significantly reduced, compared with those of pre-intervention (P＜ 0.01); the difference after post-intervention was reduced significantly, compared with those in the pre-intervention (P＜0.05). ③CMBC: The post-heating values and the difference in the experimental group were significantly higher than those in the control group (P＜0.01). There were no statistical significant inner-group difference. Conclusion: Lower limb intermittent negative pressure therapy can improve the skin microcirculation of the quadriceps of the male rowers, which has a positive effect on the rapid recovery of physical fitness. |
