摘要：

      目的:应用红外热像图方法显示运动训练前后肌肉（肌群）温度分布及其变化，探讨红外热像方法用于运动训练效果评价的可能性和价值。方法：应用红外热像仪对健康志愿受试者的上、下肢和躯干运动，以及不同负重量运动前后的相应肌群进行观察，显示肌肉的红外热像图及其变化，分析和比较肌肉运动前后温度变化以及与运动时间和负重的关系。结果：①做屈腕、屈肘、展臂、下蹲站起、俯卧撑等运动后，运动的肌肉（肌群）温度大幅升高，而相邻未运动肌肉温度的升高有限，热像图对该反应显示清晰。②俯卧撑25次后胸大肌和斜方肌温度升高0.35℃和0.28℃，俯卧撑50次升温为1.21℃和0.32℃。③负重1kg屈腕100次后前臂肌群升温1.32℃，负重2.5kg升温1.85℃。结论：具有定性、定位和动态优势的红外热像技术对运动后肌肉的升温反应可以记录和显示，而肌肉升温的高低与训练时间的长短、负重量的大小直接相关，红外热像法可用于运动员训练和患者康复训练的效果的评价。

Abstract:

      Objective: To observe the temperature distribution and changes of muscles before and after exercises with infrared（IR） thermoimaging, and to explore the possibility and value of IR thermoimaging for evaluating effects of rehabilitation training. Method：The temperature images of correlative trained muscle groups were respectively displayed by IR thermoimaging. The temperature changes were measured before and after upper limbs, lower limbs and trunk exercises, and different weight-carrying exercise, in ten volunteers. The relation of elevated temperature in muscles with exercises duration and carrying weight were analyzed and compared. Result：①After wrist flexion, elbow flexion, arm abduction, squatting down and standing up, and push-up, the temperature-elevating responses of correlative muscles (muscle groups) could be displayed clearly by thermoimage, while the temperatures of adjacent non-exercises muscles(muscle groups) elevated a little.②The temperature of pectoralis major muscle and trapeziums muscle elevated 0.35℃ and 0.28℃ after push-up 25 times, and elevated 1.21℃ and 0.32℃ after push-up 50 times. ③The temperature of forearm muscle group temperature elevated 1.32℃ after wrist flexion 100 times with heavy-carrying 1.0kg, and elevated 1.85℃ with heavy-carrying 2.5kg. Conclusion：The muscle temperature changes after exercises can be recorded and displayed by IR thermoimaging with the advantage of qualitative, locating and dynamic monitoring sports effectiveness with images. The temperature elevating of trained muscles are directly related with the exercises duration and carrying weight during exercises. IR thermoimage has practical value in evaluation for exercises effect.
