Study of Exercise Time Models on Weight Loss and Coronary Risk Panel in Inactive Middle-aged Men by Overweight or Obesity

Background & Aims: There are different methods concerning the exercise time duration, but information about its various models in middle-aged men is yet inadequate. The present study was meant to decide the interval training effects on losing weight and lipid profile and compare its efficiency with continuous training. Materials & Methods: The statistical population of this randomized trial (the CONSORT statement) research consisted of 82 middle-aged men (age 45 to 65 years old) via overweight or obesity who had come to the Hermas Sports Club of Zahedan during the summer of 2017. In the beginning, participants fulfilled anthropometric measurements for body height and weight after getting a medical certificate. Body mass index was computed as body weight (kg) /height (m2). Following these steps, they were classified according to BMI into overweight or obese. Of all 82 participants, 70 persons ended the study. They were randomly partitioned into two groups, including continuous training, and interval training. The weight assessment parameters, including the change in weight and body composition, blood sample tests were performed before and 12 weeks after the study. Results: Compared to baseline, all parameters changed significantly in the groups. The increase in High-density lipoprotein cholesterol (HDL-C) within the groups showed a significant difference (P <0.001). Drop in the proportion of total cholesterol to the HDL-cholesterol in interval training was higher than the continuous training group. The confidence level of the results was 95%. Conclusion: Both experimental groups confirmed a similar weight cut. Interval training impact on lipid profile had some advantage as compared to the continuous training. These findings will improve our knowledge about exercise time models for middle-aged men and while preventing cardiovascular accidents can contribute to choosing more effective exercise training program for losing weight.
