| Abstract
Background & Purpose: Adipose tissue have an important role in inducing lung dysfunction through production and secretion of adipokins such as leptin. The aim of this study was to investigate the effect of a period of aerobic training on lung function indices and serum leptin levels in obese men.
Methods: Twenty three overweight and obese subjects were randomly assigned to aerobic training (obese EX, n = 12) (45.26±2.45 yr, body mass index (BMI) 31.81±0.77 kg/m2) and control (obese CON, n = 11) (47.03±3.36 yr, body mass index (BMI) 31.45±0.96 kg/m2) groups. Another control group (n = 9) was sampled from normal weighed individuals to compare at the base level (45.1±4.1 yr, body mass index (BMI) 24.63±0.45 kg/m2). The obese EX group participated in 12 weeks of progressive aerobic training 3 sessions a week. Body composition (CT scan), serum leptin levels and lung (pulmonary) function were measured before and after training.
Results: At the baseline, the normal weight participants had significant lower serum leptin concentration and higher lung function compared with obese participants (P<0.05). Also, the results indicated that there is an inverse correlation between leptin and obesity with lung function indices (P<0.05). After the aerobic training, obesity and lung function indices were significantly improved (P<0.05). In contrast, serum leptin concentration was significantly decreased after the aerobic training program (P<0.05).
Conclusion: Aerobic exercise improves indices of obesity and lung function in obese men which is associated with reduced levels of leptin.
