Lack of regular exercise might cause functional performance and overall health to deteriorate more quickly in adults. There is little evidence to support the use of high-intensity interval training (HIIT) in elderly individuals to yield health advantages, despite the fact that it has been successfully employed in young and clinical groups. Therefore, the main objective of this study was to determine how HIIT affected older people’s health-related results. 24 sedentary individuals consented to take part in the 16-week HIIT and control intervention. Before and after the intervention, measurements of body composition, insulin resistance, blood lipids, functional ability, cardiorespiratory fitness, and quality of life were taken. Cohen’s effect sizes were used to estimate the extent of group differences, and paired t-tests were used to compare pre- and post-group changes. The effects of time x group interaction between HIIT and control were assessed using a 2×2 ANOVA. With both groups, there was a noticeable improvement in body fat percentage, sagittal abdominal diameter, waist circumference, and hip circumference. HIIT significantly enhanced cardiorespiratory fitness and fasting plasma glucose compared to the control. In comparison to the control group, HIIT dramatically improved the lipid profile and functional performance. These results demonstrated that HIIT is a practical, enjoyable, and beneficial form of exercise for adults.
