Background and Aims: Adipolin is an anti-inflammatory adipokine that plays a role in insulin resistance. This study aimed to examine the changes in plasma levels of adipolin and some body composition indices in overweight and obese women following eight weeks of intense interval training.
Materials and Methods: This quasi-experimental and applied study was performed on 30 subjects who were purposefully selected and randomly divided into two experimental and control groups (n=15). The intense interval-training program consisted of running for four minutes at an intensity of 45-60% of maximum heart rate. The first training session was performed at 45% of maximum heart rate, and gradually the intensity of the training was increased by 5% each week. After reaching an intensity of 60% of the heart rate, it was maintained until the end. Blood sampling was performed after 12 h of fasting in two stages, before and after the test, and the research variables were measured. Data were analyzed in SPSS software (version 24). For intra- and inter-group changes, dependent t-test and independent t-test were used at a significance level of P≤0.05.
Results: According to the independent t-test, the values of adipolin, body mass index, body weight, and waist to hip ratio in the experimental group were significantly different from those in the control group (P<0.05). Moreover, according to the dependent t-test, the values of adipolin increased significantly after eight weeks of training, but body weight, BMI, and WHR decreased significantly (P<0.05).
Conclusion: In conclusion, regarding the increase in adipolin and the decrease in some body composition indices, it is recommended that overweight and obese individuals use high-intensity interval training methods to prevent obesity-related diseases.
