Respiratory disorders may be one of the adverse effects of sedentary lifestyle. This study investigated respiratory functions (FEV, FVC and PEFR) and anthropometric parameters (body weight and body mass index) of healthy young males and females participating in moderate aerobic exercise Forty young healthy untrained non-athletes, twenty males and twenty females (age, 25 ± 5.6 years; body weight, 65 ± 4.0 kg; body height, 176.9 ± 2.5 cm) volunteered to participate in this study. The exercise regimen was of moderate intensity lasting for 20 min daily on a treadmill consistently at the speed of 13 km/h for 14 days. The weight and height of participants were measured using medical scale and wall-mounted stadiometer respectively. The forced expiratory volume in 1 s (FEV), forced vital capacity (FVC) and peak expiratory flow rate (PEFR) were assessed using digital spirometer. The results showed a significant (p < 0.05) decrease in body weight and body mass index of female participants after 14 days of exercise regimen. The FEV, FVC and PEFR were significantly increased (p < 0.05) in both male and female subjects after exercise. The Pearson correlation showed a significant (p < 0.05) positive correlation between BMI with FEV/FVC% in female participants. There was an increase in calories burnt from day 4 of the study in both male and female participants. It is concluded that moderate aerobic exercise improved respiratory functions (FEV, FVC and PEFR) in both male and female subjects with greater improvement in females while reducing body weight and body mass index in females.
呼吸系统疾病可能是久坐不动生活方式的不良影响之一。本研究调查了参与适度有氧运动的健康年轻男性和女性的呼吸功能（第一秒用力呼气量、用力肺活量和呼气峰值流速）以及人体测量参数（体重和体重指数）。四十名年轻健康的未经训练的非运动员，二十名男性和二十名女性（年龄，25±5.6岁；体重，65±4.0千克；身高，176.9±2.5厘米）自愿参与本研究。运动方案为中等强度，每天在跑步机上以13公里/小时的速度持续进行20分钟，共14天。分别使用医用秤和壁挂式身高计测量参与者的体重和身高。使用数字肺量计评估第一秒用力呼气量、用力肺活量和呼气峰值流速。结果显示，运动方案进行14天后，女性参与者的体重和体重指数显著下降（p<0.05）。运动后，男性和女性受试者的第一秒用力呼气量、用力肺活量和呼气峰值流速均显著增加（p<0.05）。皮尔逊相关性分析显示，女性参与者中体重指数与第一秒用力呼气量/用力肺活量百分比之间存在显著的正相关（p<0.05）。从研究的第4天起，男性和女性参与者的卡路里消耗量均有所增加。得出的结论是，适度有氧运动改善了男性和女性受试者的呼吸功能（第一秒用力呼气量、用力肺活量和呼气峰值流速），女性改善更为明显，同时降低了女性的体重和体重指数。
