Aim:Obesity is known as an inflammatory systemic indicator of various diseases. The aim of the present study was to investigate the effect of 12 weeks of progressive resistance exercise on serum levels of enzymes aspartate aminotransferase, alkaline phosphatase and alanine aminotransferase in obese men.
Method:Forty sedentary obese men (BMI=31.07 kg.m2) with age range of 30-45 years were purposefully selected and randomly divided into two groups of 20 participants: progressive resistance exercise and control. The exercise protocol for 12 weeks, was carried out three times a week (First week:15 repetitions -2 rounds -50% 1RM; Twelfth week:12 repetitions -3 rounds -80% 1RM).
Blood samples were taken before and 24 hours after the last training session to determine serum concentrations of aspartate aminotransferase, alkaline phosphatase, and alanine aminotransferase. Data were analyzed using independent and dependent t-test at a significance level of α=0.05.
Results:The results showed that 12 weeks of progressive resistance training has significant effect on between group changes of aspartate aminotransferase(p=0.003), alkaline phosphatase (p=0.014), alanine aminotransferase(p=0.040) and the ratio of aspartate aminotransferase to alanine aminotransferase(p=0.006) in sedentary obese men. Significant between group changes were observed in muscle strength(p=0.001) and body fat percentage(p=0.038). Progressive resistance training is likely to reduce the concentration of aspartate aminotransferase, alkaline phosphatase, and alanine aminotransferase in the blood of obese obese men by improving body composition, muscle strength, and oxygen consumption.
Conclusion:Progressive resistance training, possibly with improved body composition and muscle strength, can decrease the concentration of aspartate aminotransferase, alkaline phosphatase, and alanine aminotransferase in sedentary obese men.
