文题释义:
近红外光谱(near infrared reflectance spectroscopy,NIRS):是介于可见光(Vis)和中红外(MIR)之间的电磁辐射波,美国材料检测协会(ASTM)将近红外光谱区定义为780-2 526 nm的区域,是人们在吸收光谱中发现的第一个非可见光区。近红外光谱区与有机分子中含氢基团(O-H、N-H、C-H)振动的合频和各级倍频的吸收区一致,通过扫描样品的近红外光谱,可以得到样品中有机分子含氢基团的特征信息,而且利用近红外光谱技术分析样品具有方便、快速、高效、准确和成本较低、不破坏样品、不消耗化学试剂及不污染环境等优点,因此该技术受到越来越多人的青睐。
静力性拉伸(static stretching,SS):是指将韧带、肌肉等软组织缓慢的牵拉至最大可忍耐的长度,并保持这种牵拉静止不动一定时间的拉伸方法,如压腿、下腰、压肩等;研究显示静力性拉伸的效应主要体现在扩大关节活动范围、预防运动损伤以及增加肌肉力量等3个方面。
 
摘要
背景:目前虽有众多对不同拉伸方法比如静力性和动力性拉伸效果的评价研究,但是缺乏现代科学标准客观化指标,尤其是能实时检测的生理性指标,另外其疗效机制也尚不明确。
目的:利用近红外光谱技术测量验证静力性拉伸的不同拉伸方式——主动与被动拉伸对肌肉组织血流及血氧的影响变化,从生理性缺血及再灌注方面探索拉伸作用的机制。
方法:对10名平均年龄为(28±5)岁年轻健康的受试者,3名男性,7名女性,使用集成了三波长LED光源的PortaLite NIRS血氧计分别检测不同方式的静态拉伸(主动拉伸和被动拉伸)处于拉伸和收缩状态肌肉组织血氧变化,包括基线、拉伸干预期间及干预后的氧合血红蛋白、脱氧血红蛋白和总血容量变化。
结果与结论:①静态拉伸时处于拉伸状态的肌肉组织通过增加总血容量明显提升血液氧合血红蛋白水平,而处于收缩状态的肌肉组织总血容量、脱氧血红蛋白和氧合血红蛋白抑制效果较明显,且收缩的组织各血液指标上升幅度不如拉伸组织;②主动拉伸运动后上调总血容量和氧合血红蛋白能力优于被动拉伸,有促进血液微循环和血流动力学活性、增强局部组织血氧、增加组织柔韧性以及加速局部组织修复或提升组织功能的可能性;③结果提示近红外光谱检测组织血氧技术有望成为验证组织再生与康复的一个客观指标。

Abstract:

BACKGROUND: There are many evaluation studies on the efficacy of different stretch methods such as static and dynamic stretches, but the objective index of modern scientific standards, especially physiological indicators are absent. Moreover, the underlying mechanism is not yet clear.

OBJECTIVE: To measure and verify the effects of static tensions (active and passive stretching) on the muscle blood flow and blood oxygen by using near-infrared spectroscopy, and to explore the mechanism of stretching from the aspect of physiological ischemia/reperfusion.
METHODS: Ten young healthy subjects (3 males and 7 females) with a mean age of (28±5) years were enrolled. NIRS Oximeter which integrated three-wavelength LED light sources was used to detect the blood oxygen in the muscle tissue under stretching and contraction under active stretching and passive stretching. The indicators included the oxyhemoglobin, deoxyhemoglobin, and total blood volume at baseline, during stretching and after intervention.
RESULTS AND CONCLUSION: (1) The blood oxyhemoglobin level of the muscles in stretched state was obviously increased with total blood volume increasing. The total blood volume, deoxyhemoglobin and oxyhemoglobin in contractile muscles were suppressed significantly and the increasing degree of blood indexes were less than that after the stretching exercise. (2) The increases of total blood volume and oxyhemoglobin after active stretching exercise were higher than those after passive stretching, which could promote blood microcirculation and hemodynamic activity, increase local blood oxygen and the flexibility of tissue, accelerate local tissue repair or enhance the tissue function. (3) These results indicate that near-infrared spectroscopy to detect tissue blood oxygen is expected to be an objective index for verifying tissue regeneration and rehabilitation.
