The Impact of High-Intensity Interval Training on Cardiovascular Health in Sedentary Young Adults: A Randomized Controlled Trial

Thesis Abstract

Abstract
This thesis investigates the impact of high-intensity interval training (HIIT) on cardiovascular health in sedentary young adults through a randomized controlled trial. The study aims to explore the effectiveness of HIIT as an intervention to improve cardiovascular health markers in this specific population. Sedentary lifestyle is a growing concern due to its association with various cardiovascular risk factors, such as obesity, hypertension, and dyslipidemia. HIIT has gained popularity as a time-efficient exercise regimen that can potentially offer significant health benefits. The research design includes a randomized controlled trial with a sample of sedentary young adults aged between 18-30 years. Participants will be randomly assigned to either the HIIT intervention group or a control group. The HIIT intervention will consist of structured high-intensity exercise sessions performed over a specified duration, while the control group will maintain their sedentary lifestyle. Pre- and post-intervention assessments will be conducted to evaluate changes in cardiovascular health markers, including blood pressure, body composition, lipid profile, and aerobic fitness. The literature review provides a comprehensive overview of existing research on the effects of HIIT on cardiovascular health, sedentary behavior, and exercise interventions in young adults. Key findings from previous studies highlight the potential benefits of HIIT in improving cardiovascular health outcomes, such as reducing body fat, improving lipid profiles, and enhancing aerobic capacity. The research methodology section outlines the study design, participant recruitment process, intervention protocol, outcome measures, data collection procedures, and statistical analysis plan. The discussion of findings chapter will present the results of the study, including changes in cardiovascular health markers between the HIIT group and the control group. The conclusion will summarize the key findings, implications for practice, limitations of the study, and recommendations for future research. Overall, this thesis aims to contribute to the growing body of evidence on the effectiveness of HIIT as an intervention to improve cardiovascular health in sedentary young adults. The results of this study may have implications for developing targeted exercise programs to promote cardiovascular health and reduce the risk of cardiovascular diseases in this at-risk population.
