Introduction: The aim of the present study was to investigate the effect of high-intensity interval training and continuous training on the serum levels of fetuin A and fetuin B in obese men.
Method: For this purpose, after homogenization, 45 obese males (Weight: 94.65±2.02 kg, Age: 26±5 yrs, BMI: 33.62±1.41 kg.m2) were randomly divided into 3 groups: control group (15 people), continuous training group (15 people), and interval training group (15 people) based on individual characteristics. The training groups were done in 12 weeks and 3 sessions per week. Interval training consisted of 6 bursts of 3-minute at 90% of maximal oxygen uptake (VO2 max) running, with 3 minutes of active recovery between each burst at 50% VO2 max running on a treadmill. Continuous training consisted of 50 minutes of running at 70% of VO2 max running on a treadmill. Blood samples were taken before and 48 hours after the last training session and were used for index analysis using an ELISA device.
Results: Analyses covariance test for the plasma levels of fetuin A and fetuin B showed that the difference between groups (control, MICT and HIIT) was statistically significant (p<0.001). According to the results of post hoc Bonferroni test for fetuin A level, there is a significant difference between the HIIT (p<0.001) and MICT (p=0.007) groups with the control group. Also, based on the results of post hoc Bonferroni test for fetuin B levels, there is a significant difference between the HIIT (p<0.001) and MICT (p<0.001) groups with the control group. In addition, fetuin B reduction in the HIIT group compared to MICT group was statistically significant (p<0.001).
Conclusion: The present results showed that although both MICT and HIIT had positive effects on reducing plasma levels of hepatokines (fetuin-A and fetuin-B), HIIT was more effective in influencing these variables. Specifically, HIIT resulted in a greater reduction in fetuin-B levels compared to MICT, while no significant difference was observed between the training groups in terms of fetuin-A levels.
