The Effect of High-Intensity Interval Training on Weight Loss Among Adults

Abstract

High-intensity interval Training (HIIT) has been recognized for its potential to improve weight management and metabolic health, particularly among individuals with mental health conditions such as schizophrenia. This study aims to evaluate the effects of a 10-week HIIT program on weight loss among adults with schizophrenia, addressing the challenges of medication-induced weight gain and sedentary lifestyles. A quasi-experimental study was conducted at the Dadi Regional Special Hospital in Makassar, Indonesia, involving 40 male participants aged 19-49 years. Participants engaged in 25-minute HIIT sessions three times per week for 10 weeks. Weight measurements were taken at baseline and after the intervention. Heart rate monitoring ensured participants reached the anaerobic zone (80-90% of maximum heart rate). Data were analyzed using univariate and bivariate tests. Participants experienced a statistically significant reduction in mean body weight, from 55.800 kg to 55.325 kg (p = 0.001). The intervention demonstrated the effectiveness of HIIT in promoting weight loss, even in a psychiatric population.HIIT is an effective strategy for managing weight among adults with schizophrenia, potentially mitigating the adverse effects of antipsychotic medications. This study highlights the feasibility of implementing structured HIIT programs in psychiatric settings to improve both physical and mental health outcomes. Future research should explore long-term sustainability and the integration of dietary interventions to enhance the effectiveness of weight management strategies.
