- Brief Summary
Abstract: Purpose: This study aimed to investigate the effects of on-line high-intensity interval training (HIIT) in abdominal obese women experiencing health complications due to COVID-19. Methods: Sixteen participants were enrolled and divided into the HIIT group (n=8) and moder-ate-intensity continuous training (MICT, n=8) group. The HIIT group underwent 20 minutes of exercise consisting of 20 seconds of high-intensity (85–90% HRmax) exercise followed by 30 sec-onds of exercise at 60% HRmax using only body weight. The main exercise program for the MICT group included 40 minutes of stationary bike pedaling at 65–70% HRmax. Exercise was per-formed three days a week for eight weeks using a smart device and application that enables bidi-rectional communication. Results: The HIIT group showed reduced body fat (p=.036), BMI (p=.021), and visceral fat (p=.003) compared to the MICT group. Further, the HIIT group also had reduced insulin (p=.021) and LDL levels (p=.024), increased grip strength (left p=.012, right: p=.002), and a substantial drop in total stress index (p=.004) compared to the MICT group. Con-clusions: Thus, on-line HIIT is a useful means to alleviate abdominal fat induced, improve blood lipid profile, and muscle strength, and relieve stress caused by COVID-19.
