Abstract:
Abstract: Backgroundː Overweight and obesity are common health conditions that continue to increase. Specifically, central obesity has a strong correlation with increasing risk of cardiovascular and metabolic diseases. The accumulation of visceral fat in this type of obesity is reported to play a key role in various pathogenesis of these diseases. Methodsː 20 healthy overweight men (BMI=23–25) were enrolled for this study. Participants were divided into two groups: The HIIT group (n=12) and the control group (n=8). The intervention group performed high-intensity interval training (HIIT) three times per week for three weeks, 15–25 min per session; the control group was not allowed to perform any exercises during the study. Visceral fat masses were assessed using waist circumference and visfatin serum level. Resultsː the HIIT group demonstrated a significant reduction (p=0.019) in visfatin serum levels compared to the control group. However, there was no significant reduction (p=0.991)
in waist circumference of either group after training. Conclusionː HIIT protocol reduces serum visfatin levels in overweight males. This effect may be achieved by increasing intra-abdominal fat oxidation, which is the specific site for visfatin synthesis.
