Thesis Abstract

Abstract
High-intensity interval training (HIIT) has gained significant attention in recent years for its potential benefits on cardiovascular health. This study aims to investigate the effects of HIIT on cardiovascular health in sedentary individuals. The research involved a comprehensive literature review to establish the background and theoretical framework for the study. The methodology included recruiting sedentary individuals and implementing a structured HIIT program over a specified period. Various parameters, including heart rate, blood pressure, lipid profile, and aerobic capacity, were measured before and after the intervention to assess changes in cardiovascular health. The findings of this study revealed that sedentary individuals who participated in the HIIT program experienced significant improvements in cardiovascular health indicators. Specifically, there were notable reductions in resting heart rate, blood pressure, and LDL cholesterol levels, while aerobic capacity showed a substantial increase. These outcomes suggest that HIIT can be an effective intervention for improving cardiovascular health in sedentary individuals. The discussion delves into the mechanisms underlying the positive effects of HIIT on cardiovascular health, including improvements in aerobic fitness, vascular function, and metabolic profile. The results are compared and contrasted with existing literature to provide a comprehensive understanding of the topic. The limitations of the study, such as the sample size and duration of the intervention, are also acknowledged, along with suggestions for future research. In conclusion, this study demonstrates the beneficial impact of HIIT on cardiovascular health in sedentary individuals. The findings support the integration of HIIT into physical activity recommendations for individuals looking to improve their cardiovascular fitness. This research contributes to the growing body of evidence highlighting the effectiveness of HIIT as a time-efficient and potent strategy for enhancing cardiovascular health in sedentary populations.

Thesis Overview

**Research Overview: The Effects of High-Intensity Interval Training on Cardiovascular Health in Sedentary Individuals** Cardiovascular diseases are a leading cause of mortality worldwide, with sedentary lifestyles being a significant risk factor. High-Intensity Interval Training (HIIT) has gained popularity as an effective and time-efficient exercise regimen that may improve cardiovascular health. This research aims to investigate the effects of HIIT on cardiovascular health in sedentary individuals to provide insights into its potential as a preventive or therapeutic intervention. The project will commence with a comprehensive review of existing literature on HIIT and its impact on cardiovascular health. This will establish a foundation for understanding the potential mechanisms through which HIIT may influence cardiovascular parameters such as blood pressure, heart rate, lipid profile, and vascular function. The literature review will also explore the role of exercise intensity, duration, frequency, and mode in determining the cardiovascular benefits of HIIT. Subsequently, the research methodology will be outlined, detailing the study design, participant recruitment criteria, intervention protocol, outcome measures, and data analysis methods. Sedentary individuals will be recruited and randomly assigned to either a HIIT group or a control group. The HIIT group will undergo a structured HIIT program consisting of alternating periods of high-intensity exercise and rest, while the control group will maintain their sedentary lifestyle. Data collection will involve pre- and post-intervention assessments of cardiovascular parameters using non-invasive techniques such as blood pressure monitoring, electrocardiography, lipid profiling, and vascular ultrasound. Additionally, subjective measures of exercise tolerance, quality of life, and perceived exertion will be recorded to evaluate the feasibility and acceptability of HIIT in sedentary individuals. The discussion of findings will present the results of the study, comparing changes in cardiovascular health parameters between the HIIT and control groups. Potential correlations between adherence to the HIIT program, changes in fitness levels, and improvements in cardiovascular health will be explored. The implications of the findings for public health promotion, clinical practice, and future research directions will also be discussed. In conclusion, this research project seeks to advance our understanding of the effects of HIIT on cardiovascular health in sedentary individuals. By elucidating the potential benefits and limitations of HIIT as an exercise intervention, this study aims to inform evidence-based recommendations for promoting cardiovascular health and reducing the risk of cardiovascular diseases in sedentary populations.
