The purpose of this study was to identify the effect of High Intensity Interval Training on plasma Apelin, cardiovascular risk factor and body composition in obese men and to provide effective basic information about obesity in the field of exercise prescription.
This study selected thirty research subjects(male) from K university that satisfy the three standards of obesity. The subjects were divided into 3 groups consisting of High Intensity Interval Training(HIIT, n=9), Moderate Aerobic Training(MAT, n=9) and Control(CON, n=9) with 9 members, respectively.
The research period was 6 weeks and the subjects were all tested with body composition including blood test and maximal graded exercise test before the experiment and after six weeks.
The research followed these steps:
High Intensity Interval Training(HIIT) group used cycle for 2 weeks in mid-high intensity and in the following 4 weeks escalated the intensity of the workout every week until it reached 90% HRmax.
Moderate Aerobic Training(MAT) group have cycled continuously at a moderate level with intensity of 50-60% HRmax.
Control(CON) have not been trained in any way and have been measured at the beginning and end of the experiment.
The collected data were statistically analyzed with SPSS Ver.22.0 and all the measurements have been recorded in average and standard deviation. To find out the change within the groups according to the time of measurement, paired t-test was used. Also to identify interaction in the change within and out of the groups Mixed design ANOVA was used. repetition contrast is post-hoc test used and statistical significance level was set p<.05 selected.
The following are the results:
Control(CON): A total of 9 males were recruited, however 2 of them were not selected due to injury and personal reasons. Therefore 7 males have participated in the measurement.
1. The results showed that the blood Apelin-36 concentration have decreased significantly among HIIT group compared to MAT.
2. There was no significant change observed in the blood hs-CRP concentration before and after the experiment within obese men in HIIT group but a decrease has been observed in the MAT group.
3. Obese men in HIIT group have shown decrease in Fasting blood level, Insulin, HOMA-IR compared to MAT group.
4. HIIT group participants have shown more decrease in waist measurement, percentage of body fat, amount of body fat, weight, BMI, and WHR compared to MAT group participants.
5. Exercise test before and after the experiment showed that HIIT group members have shown more increase in cardio functions than the members who went through MAT.
In conclusion, this research has concluded that the obese men who have gone through HIIT have shown positive blood Apelin-36, blood hs-CRP, Triglyceride, Glucose, Insulin, HOMA-IR figures than the participants in MAT and Controlled group. Also physical changes such as waist measurement, percentage of body fat, amount of body fat, weight, BMI, WHR have been observed in the HIIT group. Exercise test also showed that the level of cardio functions have increased significantly in HIIT group compared to other groups.
