Abstract
The aim of this study was to investigate the effect of 8 weeks of high intensity and moderate intensity continuous exercise training on levels of 15-GDF, troponin and CRP in youth. This is a quasi-experimental and applied research. In the present study, the statistical population included all obese young men (BMI>30)) in Zahedan. In this study, 45 subjects were divided into 3 groups: high intensity intermittent exercise (S=15), moderate intensity continuous exercise (S=15) and control group (S=15). They did three sessions per week for 8 weeks. Intermittent exercise with a intensity of 55 to 90% of maximum heart rate and continuous exercise with moderate intensity consisted of 40 minutes of running with intensity of 40 to 75% of maximum heart rate.
Blood sampling was measured 24 hours before the first and 48 hours after the last training session in Zahedan trust laboratory.
To test the normality of the data Kolmogorov-Smirnov test were used, then the dependent t-test was used to examine within-group changes and independent t-test was used to examine inter-group changes.
The results showed that there was a significant difference between 8 weeks of moderate intensity continuous training on the levels of GDF-15, troponin I and CRP in the youth with moderate fasting and also in the control group (P <0.05). There was also a significant difference between the response of 8 weeks of high intensity intermittent exercise on the levels of GDF-15, troponin I and CRP in the youth in comparison to the medium intensity and the control group (P≤0.05).
The results of this study showed that high intensity and moderate intensity intermittent exercise on the levels of GDF-15, troponin I and CRP in young people were significantly different from pre-exercise levels. Therefore, both methods of exercise have positive and significant effects on improving aerobic power. Based on the characteristics of the subjects such as age, sex, physical health status, etc, different types of aerobic exercises with different intensities can be used to improve the existing condition.
