| 中文摘要 | 目的:研究同一疲劳模式下,不同方式恢复过程中肌肉氧含量变化特点及特征指标的关联性,探讨下肢负压-常压体能快速恢复舱对运动性疲劳恢复的快速有效性。方法:运动员通过设计的运动训练疲劳模式运动后,分别采用进舱恢复、传统恢复(15 min慢跑和15min人工按摩)和自然恢复(静止休息)三种恢复方式(30 min)进行运动性疲劳恢复。用近红外光谱技术实时监测受试者在不同方式恢复过程中股外侧肌组织肌氧参数变化,计算并分析肌氧恢复幅度(H)、半恢复时(TR),肌氧半恢复速率(RHb O2);同时记录受试者的主观感觉疲劳程度和心率等参数。结果:1)30 min恢复期的第10 min时,进舱恢复组肌组织氧合血红蛋白浓度的增量(ΔCHb O2)高于自然恢复组(P<0.05),且5 min至10 min之间ΔCHb O2呈上升趋势,而此时传统恢复组肌组织ΔCHb O2和自然恢复组无差异(P>0.05)。2)恢复过程后期肌氧的变化:进舱恢复组的恢复效果与传统恢复组基本相同,且明显好于自然恢复组(P<0.01)。3)恢复后即刻相关指标变化:心率和主观疲劳感觉无明显差异。结论:1)在恢复初期,快速恢复舱这种早期的快速恢复肌肉氧含量的优势可以较好地运用于实战比赛,如举重等的短时间休息间隙。2)体能快速恢复恢复舱在整个恢复过程中具有加速血液和淋巴系统循环,改善毛细血管功能,促进肌氧含量快速恢复的作用,为运动员的体能快速恢复提供了一种新的途径,具有广阔的应用前景。; Objective:To study characteristics of changes in muscle oxygen content and relevance of feature index during recovery process using different recovery modes after the same training-to-fatigue program,and to investigate the fast effect of recovery from sports fatigue by rapid recovery cabin(RRC) for physical fitness with leg negative-normal pressures.Methods:Athletes trained to fatigue by the same training-to-fatigue program,then immediately to be assigned randomly to 3groups using 3 different recovery modes including RRC(30 min),traditional recovery(TR)(15 min jogging + 15 min massage) and spontaneous recovery(SR)(30 min static rest).Real time parameters in muscle oxygen content of vastus lateralis were monitored and recorded by near-infrared spectroscopy,and recovery amplitude of muscle oxygen content(H),half recovery time(TR),half recovery rate(RHb O2) were calculated and analyzed.Rate of perceived exertion(RPE) and heart rate(HR) were also recorded and analyzed.Results:1) From 5 to 10 min of 30 min recovery process,the increment of muscle oxygenated hemoglobin concentration(ΔCHb O2) of athletes in RRC showed an increasing trend.At 10 min,the ΔCHb O2 of athletes in RRC was significantly higher than that of SR group(P < 0.05),but the ΔCHb O2 of athletes in TR group was not significantly higher than that of SR group(P > 0.05).2) Following 10 min,both ΔCHb O2 in RRC and TR groups were respectively higher than that of SR group(P < 0.01).3) RPE and HR were not significantly different from each other between the two of three groups during recovery process.Conclusion:1) RRC has faster effect on recovery from sport fatigue than that of other two recovery methods,which could be used in practical match.2) RRC has effects in accelerating circulation of blood and lymphatic system,improving capillary function and facilitating muscle oxygen content recovery rapidly,which supplies a new way for athlete physical fitness recovery from sports fatigue and has a broad application prospect. |
