The present study aimed to compare the effects of indoor versus outdoor aerobic exercise through the evaluation of pollution exposure, changes in cognitive function, and biochemical variables in elderly individuals. Forty-eight volunteers, aged 60 years or older, were randomly assigned to 4 groups: control indoor, control outdoor, indoor exercise, and outdoor exercise (n = 12/group). Atmospheric concentration of 5 pollutants was monitored. Cognitive function and biochemical analysis were done after 12 weeks. All pollutants measured were significantly higher outdoor (p < 0.05). Temperature was not different between indoor and outdoor environment along 12 weeks (p > 0.05). Indoor aerobic exercise presented lower concentration of pollutants, improved cognitive function, and enhanced brain-derived neuro factor (BDNF) levels when compared to outdoor (p < 0.05). Indoor aerobic exercise showed significant glycemic reduction compared to other groups (p < 0.05). Indoor aerobic exercise presents lower concentration of pollutants than outdoor and provides better benefits to the management of glycemia, improves cognition, and enhances BDNF levels.

本研究旨在通过评估老年人的污染暴露、认知功能的变化和生化变量来比较室内和室外有氧运动的影响。48 名年龄在 60 岁或以上的志愿者被随机分配到 4 组：控制室内、控制室外、室内运动和室外运动（n  = 12/组）。监测了 5 种污染物的大气浓度。12周后进行认知功能和生化分析。所有测量的污染物在室外都显着较高（p  < 0.05）。12 周内室内外环境温度无差异 ( p > 0.05）。与室外相比，室内有氧运动的污染物浓度较低，认知功能得到改善，脑源性神经因子 (BDNF) 水平提高 ( p  < 0.05)。与其他组相比，室内有氧运动显示出显着的血糖降低（p  < 0.05）。室内有氧运动的污染物浓度低于室外，并且对血糖管理、改善认知和提高 BDNF 水平提供更好的益处。
