Thesis Abstract

Abstract
High-Intensity Interval Training (HIIT) has gained popularity in recent years due to its effectiveness in improving cardiovascular fitness in various populations. This study aimed to investigate the impact of HIIT on cardiovascular function in sedentary individuals. The research design involved a randomized controlled trial with a sample of sedentary adults aged 25-40 years. The participants were divided into two groups the HIIT intervention group and the control group. The HIIT group underwent a 12-week supervised exercise program consisting of high-intensity intervals, while the control group maintained their sedentary lifestyle. The study assessed various cardiovascular parameters, including heart rate, blood pressure, VO2 max, and lipid profile, before and after the intervention. Additionally, participants were monitored for adherence to the exercise program and any adverse events. Statistical analysis was conducted to compare the changes in cardiovascular function between the two groups. The results indicated a significant improvement in cardiovascular function in the HIIT group compared to the control group. Specifically, participants in the HIIT group demonstrated a decrease in resting heart rate, systolic and diastolic blood pressure, and an increase in VO2 max. Furthermore, improvements in lipid profile, including decreased LDL cholesterol and increased HDL cholesterol levels, were observed in the HIIT group. The findings of this study highlight the positive effects of HIIT on cardiovascular function in sedentary individuals. The results suggest that HIIT can be an effective strategy to improve cardiovascular health in this population. These findings have important implications for public health, as sedentary behavior is a significant risk factor for cardiovascular diseases. Future research could explore the long-term effects of HIIT on cardiovascular function and its potential role in preventing cardiovascular diseases in sedentary individuals.

Thesis Overview

The research project titled "The Impact of High-Intensity Interval Training on Cardiovascular Function in Sedentary Individuals" aims to investigate the effects of high-intensity interval training (HIIT) on cardiovascular function in individuals with a sedentary lifestyle. Sedentary behavior, characterized by low levels of physical activity and prolonged sitting, has been linked to various health risks, including cardiovascular diseases. The study will begin with a comprehensive introduction that highlights the background of the research area, the problem statement focusing on the impact of sedentary behavior on cardiovascular health, and the objectives of the study, which include examining the effects of HIIT on cardiovascular function in sedentary individuals. The limitations and scope of the study will be clearly defined, along with the significance of the research in contributing to the understanding of how HIIT can benefit cardiovascular health in sedentary populations. The structure of the thesis will also be outlined to provide a roadmap of the research. The literature review will delve into existing studies and research findings related to HIIT, cardiovascular function, and sedentary behavior. This section will analyze and synthesize current knowledge in the field, highlighting gaps in the literature that the present study aims to address. Ten key themes will be explored, including the physiological mechanisms of HIIT, the impact of sedentary behavior on cardiovascular health, and previous research on exercise interventions in sedentary populations. The research methodology section will detail the design of the study, including participant recruitment, intervention protocols for HIIT, data collection methods, and outcome measures to assess cardiovascular function. Ethical considerations and potential biases will be addressed to ensure the validity and reliability of the findings. The research design will be described in detail, including the sample size, participant characteristics, and data analysis procedures. The discussion of findings will present the results of the study, analyzing the effects of HIIT on cardiovascular function in sedentary individuals. Key findings will be interpreted in the context of existing literature, discussing the implications for public health and clinical practice. The limitations of the study will be acknowledged, and recommendations for future research will be proposed to further explore the benefits of HIIT in improving cardiovascular health in sedentary populations. In conclusion, the research overview emphasizes the importance of investigating the impact of HIIT on cardiovascular function in sedentary individuals. By addressing this research gap, the study aims to provide valuable insights into the potential benefits of HIIT as an exercise intervention for improving cardiovascular health in sedentary populations. The findings of this study have the potential to inform health promotion strategies and contribute to the development of tailored exercise programs for individuals with sedentary lifestyles.
