摘要:

文题释义:
血流限制训练(BFRT):是指在运动期间通过特殊加压装置(一般为气动袖带或弹性绷带)对肢体(上肢和/或下肢最近端)进行外部加压,使静脉血流闭塞的同时部分阻塞动脉血流以提高训练效果的训练方法。
通气补偿阈:是指递增负荷运动中,当通气当量急剧上升同时伴随摄氧量和二氧化碳输出量快速增加时对应的强度。
最大乳酸稳态:是指在不引起血乳酸浓度持续增加前提下,一段时间内所能维持的最高负荷。
背景:血流限制结合有氧运动具有潜在的训练益处,说话测试是运动处方强度制定的便捷选择,能否将说话测试应用于血流限制有氧运动首先取决于血流限制下说话测试的信效度。
目的:探究血流限制下说话测试的信效度。
方法:对20名男性大学生进行1次最大摄氧量测试(Tmax)和3次说话测试。3次说话测试运动方案相同,其中1次全程佩带气体代谢仪测试 (TT气体),其余2次为标准说话测试。最大摄氧量测试可测得最大摄氧量(VO2max)、通气无氧阈和通气补偿阈(RCT),标准说话测试可测得最高积极状态、临界状态和消极状态对应的心率和主观疲劳度,佩带气体代谢仪测试可测得标准说话测试运动方案中各级对应的摄氧量(VO2)、心率和主观疲劳度。4次测试均全程在两侧大腿上沿佩戴绷带加压(40%动脉闭塞压)。
结果与结论:①2次标准说话测试测得的最高积极状态和消极状态功率的信度都为高;最高积极状态、临界状态和消极状态对应心率的信度为高到非常高;但最高积极状态、临界状态和消极状态对应主观疲劳度的信度为一般到中等;②最高积极状态对应的摄氧量、心率和主观疲劳度与通气无氧阈强度相关性为中等到高(R=0.47-0.63,P < 0.05);临界状态对应的摄氧量、心率和主观疲劳度与通气无氧阈强度相关性为高到非常高(R=0.63-0.84,P < 0.05);消极状态对应的摄氧量、心率和主观疲劳度与通气无氧阈强度相关性分别为中等(R=0.36,P > 0.05)、非常高(R=0.80,P < 0.01)和中等(R=0.52,P < 0.05);③最高积极状态摄氧量和主观疲劳度、临界状态摄氧量、心率和主观疲劳度与通气无氧阈强度对应值比较差异均无显著意义(P > 0.005);消极状态摄氧量和心率与通气补偿阈强度对应值比较差异均无显著意义(P > 0.005);④结果说明,40%动脉闭塞压血流限制下有氧运动中的说话测试具有高的重测信度和中等高到高的效度,能够有效评价通气无氧阈运动强度,但不能准确评价通气补偿阈强度。说话测试可作为血流限制有氧运动过程中监控低强度的一种便捷和可靠选择。

Abstract: BACKGROUND: Blood flow restriction combined with aerobic exercise has potential training benefits, and talk test is a convenient option for prescribing the exercise intensity. Whether the talk test can be applied to the blood flow restricted aerobic exercise depends on the reliability and validity of the talk test under blood flow restriction.
OBJECTIVE: To explore the reliability and validity of talk test with blood flow restriction. 
METHODS: Twenty collegiate males participated in one maximum oxygen uptake test (Tmax) and three talk tests. The protocols for the three talk tests were the same, with the one equipped with a gas metabolizer (TT-gas) throughout the whole test process, and the other two following the standard procedure (TT-standard). In Tmax, the maximum oxygen uptake, ventilatory threshold and respiratory compensation threshold were examined. In TT-standard, the corresponding heart rate and rating of perceived exertion of the last positive stage, equivocal state and negative stage were examined. In TT-gas, the corresponding oxygen uptake, heart rate and rating of perceived exertion of all steps were examined. All the four tests were fully pressurized along the bandages on both thighs (40% arterial occlusion pressure). 
RESULTS AND CONCLUSION: The reliability of corresponding power of the last positive stage and negative stage measured by two TT-standard was high. The reliability of corresponding heart rate of the last positive stage, equivocal state and negative stage was high to very high. However, the reliability of corresponding rating of perceived exertion of the last positive stage, equivocal state and negative stage was low to medium. The correlation between corresponding oxygen uptake, heart rate and rating of perceived exertion of the last positive stage and ventilatory threshold was medium to high (R=0.47-0.63, P < 0.05). The correlation between corresponding oxygen uptake, heart rate and rating of perceived exertion of the equivocal state and ventilatory threshold is high to very high (R=0.63-0.84, P < 0.05). The correlations between corresponding oxygen uptake, heart rate and rating of perceived exertion of the negative stage and ventilatory threshold were medium (R=0.36, P > 0.05), very high (R=0.80, P < 0.01) and medium (R=0.52, P < 0.05), respectively. Except for corresponding heart rate of the last positive stage, there was no significant difference between corresponding oxygen uptake, heart rate and rating of perceived exertion of the last positive stage and equivocal state and ventilatory threshold values (P > 0.005). There was no significant difference between corresponding oxygen uptake and heart rate of the negative stage and respiratory compensation threshold (P > 0.005). To conclude, the talk test in aerobic exercise with blood flow restriction under 40% arterial occlusion pressure has high retest reliability and medium to high validity, which can effectively evaluate the intensity of ventilatory threshold, but cannot effectively evaluate the intensity of respiratory compensation threshold. Talk test can be a convenient and reliable option for monitoring low intensity during blood flow restricted aerobic exercise.

Key words: talk test, blood flow restriction, exercise intensity, ventilation threshold, respiratory compensation threshold
