Effects of Two Types of Moderate- and High-Intensity Interval Training on Serum Salusin-α and Salusin-β Levels and Lipid Profile in Women with Overweight/Obesity

OBJECTIVE: The current study aimed to compare the effects of two modes of moderate- and high-intensity interval training on serum Salusin-α and Salusin-β and lipid profile in women with overweight/obesity. SUBJECTS AND METHODS: A number of forty females were assigned to each of (1) Control (BMI= 30.2 ± 2.8 kg/m(2), n=14), (2) Moderate-intensity (BMI= 31.2 ±3.3 kg/m(2), n=13) and (3) High-intensity interval training (BMI=30.9±3.4 kg/m(2), n=13) groups. The subjects of experimental groups participated in the selected interval trainings for eight weeks. The first blood sampling was performed within 48 hours prior to the first training session and the second samples were obtained 48 hours after the last training session. RESULTS: The findings revealed that there were significant increases in Salusin-α (36% vs. 3%; p = 0.001) and high-density lipoprotein levels (7% vs. 5%; P = 0.039), while significant reductions in the levels of Triglyceride (−8% vs. −9%; p= 0.012) and total cholesterol (−1% vs. −8%; P =0.01) levels of moderate- and high-intensity interval training groups, respectively. Also, there were insignificant changes in Salusin-β (−7% vs. −5%; P = 0.108), low-density lipoproteins (−3% vs. −11%; P =0.046) and very-low-density lipoprotein (−10% vs. −8%; P = 0.056) compared to control group. There were only significant differences between Salusin-α and high-density lipoprotein levels of training groups (P<0.05). CONCLUSION: It is suggested that, although improvements in lipid profile was nearly similar for two training modes, moderate intensity interval training was more effective to prevent and control atherosclerosis.
