A cluster of metabolic abnormalities are markedly higher among postmenopausal women. The present study evaluated the effects of infrared light emitting diode (LED) during treadmill training on multiple metabolic markers, body fat, dietary habits and quality of life in postmenopausal women. Forty-five postmenopausal women aged 50-60 years were randomly assigned to one of three groups, and of these, 30 women successfully completed the full study. The three groups were as follows: (i) the LED group, which performed treadmill training associated with phototherapy (n = 10); (ii) the exercise group, which carried out treadmill training only (n = 10); and (iii) the sedentary group, which neither performed physical training nor underwent phototherapy (n = 10). Training was performed over a period of six months, twice a week for 45 min per session at 85-90% of maximal heart rate (HR), which was obtained during a progressive exercise testing. The average HR and velocity during treadmill training were 144 ± 9 bpm and 5.8 ± 1.3 km/h for both trained groups. The irradiation parameters were 100 mW, 39 mW/cm and 108 J/cm for 45 min. Anthropometric data, skinfolds thickness, biochemical exams (lipid profile, glucose and insulin levels), dietary habits and quality of life were evaluated. The sum of skinfolds significantly improved in the exercise and sedentary groups (p < 0.05). Additionally, there was an improvement in lipid profile, particularly, total cholesterol and low-density lipoprotein, which reduced significantly for all groups (p ˂ 0.05). However, intake of saturated fats was significantly reduced in the sedentary group only (p < 0.05). The quality of life improved in the LED group only, with a significant reduction in the total WHQ score (p < 0.05). Physical training with or without phototherapy may improve the metabolic profile. In addition, phototherapy together with treadmill training prevented an increase in subcutaneous fat and facilitated an improved quality of life in postmenopausal women.
绝经后女性中一系列代谢异常情况明显更为常见。本研究评估了绝经后女性在跑步机训练期间接受红外发光二极管（LED）照射对多种代谢指标、体脂、饮食习惯和生活质量的影响。45名年龄在50至60岁之间的绝经后女性被随机分为三组，其中30名女性成功完成了整个研究。三组如下：（i）LED组，进行与光疗相关的跑步机训练（n = 10）；（ii）运动组，仅进行跑步机训练（n = 10）；（iii）久坐组，既不进行体育训练也不接受光疗（n = 10）。训练为期六个月，每周两次，每次45分钟，运动强度为最大心率（HR）的85 - 90%，最大心率通过递增运动测试获得。两个训练组在跑步机训练期间的平均心率和速度分别为144 ± 9次/分钟和5.8 ± 1.3公里/小时。照射参数为100毫瓦、39毫瓦/平方厘米和108焦耳/平方厘米，照射时间为45分钟。评估了人体测量数据、皮褶厚度、生化检查（血脂谱、血糖和胰岛素水平）、饮食习惯和生活质量。运动组和久坐组的皮褶总和显著改善（p < 0.05）。此外，血脂谱有所改善，特别是总胆固醇和低密度脂蛋白，所有组均显著降低（p ˂ 0.05）。然而，仅久坐组饱和脂肪的摄入量显著减少（p < 0.05）。仅LED组的生活质量得到改善，WHQ总分显著降低（p < 0.05）。有或无光疗的体育训练均可改善代谢状况。此外，光疗与跑步机训练相结合可防止绝经后女性皮下脂肪增加，并有助于改善生活质量。
