摘　　要：利用我国自主生产的近红外组织血氧参数无损监测仪对8名中长跑运动员在功率自行车上作等级递增负荷运动时,大腿股四头肌组织中肌氧含量的变化进行监测与分析,同时测量运动员的血乳酸浓度、血容量和心率的变化。结果显示肌氧含量与运动负荷、血乳酸、血容量、心率密切相关(p<0.01)。对一人经过多次测定肌氧含量和血乳酸浓度,结果呈规律性的下降和上升,每次之间数值的横向比对,没有明显变化。由此表明,可以根据运动时骨骼肌中肌氧含量的变化来判断受试者所能承受的运动强度和在对应强度下所对应的血乳酸浓度以及肌氧下降的拐点所对应的血乳酸上升的拐点。通过调查,了解NIRS技术在运动领域中的研究及应用的现状,分析存在的主要问题和今后的研究趋向。目的在于使大家通过对NIRS技术的不断了解,认识到我国自主生产的近红外组织血氧参数无损监测仪所测的肌氧含量指标,作为测定运动氧代谢能力是一项敏感的、无损的、实时可靠的指标,与传统有创的、离体的、繁琐的检测手段相比较具有不可替代的优势。The present paper discusses how to monitor and analyze the relative change in muscle oxygen content in quadriceps tis-sue,and measures and records the change in blood lactate acid concentration,blood volume and heart rate when eight players who are good at middle-distance races perform grade incremental intensity exercise on cycle ergometer by using noninvasive tissue oximeter with near infrared spectroscopy produced by China independently.The results show that muscle oxygen content has a close relationship（p＆lt;0. 01）with exercise load,blood lactic acid,blood volume and heart rate.When determined muscle oxygen content and blood lactate acid concentration was determined for many times to the same person,the test proved regular falling and rising.There was no significant changes when analyzed each set of the data was analyzed through horizontal comparison.It verifies we can judge the subjects’s endurable exercise intensity and the upward inflection point of blood lactic acid corresponding to the decreasing inflection point of blood lactate acid concentration ＆amp; muscle oxygen content according to the muscle oxygen content change of skeletal muscle while exercising.This paper shows NIRS research status and present situation in sports field through investigation,and analyzes the main trouble and research tendency in the future.By understanding NIRS technology gradually,the authors can realize that the muscle oxygen content which measured by noninvasive tissue oximeter using near in-frared spectroscopy produced by China independently is a sensitive,nondestructive,up-to-date and reliable index,it has irre-placeable advantages when compared with traditional invasive,excised and fussy test methods.
