Thesis Abstract

Abstract
This thesis investigates the effects of High-Intensity Interval Training (HIIT) on cardiovascular health in sedentary individuals through a comparative study. Sedentary lifestyles have become increasingly prevalent, leading to a rise in cardiovascular diseases. HIIT has gained popularity as an efficient exercise regimen that combines short bursts of intense activity with periods of rest or lower-intensity exercise. The primary objective of this study is to compare the cardiovascular health outcomes of sedentary individuals engaging in HIIT with those following a sedentary lifestyle without structured exercise. The research methodology includes a randomized controlled trial design with two groups an intervention group performing HIIT and a control group maintaining their sedentary lifestyle. The study population consists of sedentary individuals aged 25-45 with no prior history of cardiovascular diseases. Data collection methods include pre- and post-intervention assessments of cardiovascular health parameters such as blood pressure, heart rate, cholesterol levels, and cardiorespiratory fitness. The literature review provides a comprehensive analysis of existing studies on HIIT and its impact on cardiovascular health, highlighting the potential benefits of this exercise modality. The findings of this study are discussed in detail in Chapter Four, where the results of the comparative analysis between the intervention and control groups are presented and interpreted. The significance of this research lies in its potential to provide valuable insights into the effectiveness of HIIT as a strategy to improve cardiovascular health in sedentary individuals. By examining the physiological responses to HIIT, this study aims to contribute to the existing body of knowledge on exercise physiology and cardiovascular health. In conclusion, this thesis underscores the importance of regular physical activity, particularly HIIT, in maintaining and improving cardiovascular health among sedentary individuals. The results of this study have implications for public health policies and interventions aimed at promoting active lifestyles to reduce the burden of cardiovascular diseases in sedentary populations.

Thesis Overview

Research Overview: The project titled "The Effects of High-Intensity Interval Training on Cardiovascular Health in Sedentary Individuals: A Comparative Study" aims to investigate the impact of high-intensity interval training (HIIT) on cardiovascular health among individuals with a sedentary lifestyle. Sedentary behavior, characterized by prolonged sitting or low levels of physical activity, has been associated with an increased risk of cardiovascular diseases such as hypertension, heart disease, and stroke. The study will compare the effects of HIIT, a form of exercise that involves short bursts of intense activity followed by brief periods of rest or lower-intensity exercise, with a sedentary control group to assess its potential benefits in improving cardiovascular health. By examining the physiological responses to HIIT, including changes in heart rate, blood pressure, cholesterol levels, and overall cardiovascular fitness, this research seeks to provide valuable insights into the effectiveness of HIIT as a potential intervention for sedentary individuals at risk of cardiovascular diseases. The research will be conducted using a comparative study design, with participants randomized into either the HIIT intervention group or the sedentary control group. Before and after the intervention period, participants will undergo comprehensive assessments of their cardiovascular health parameters, including baseline measurements of heart rate, blood pressure, lipid profiles, and physical fitness levels. The HIIT group will follow a structured exercise program tailored to their fitness levels, while the control group will maintain their sedentary lifestyle habits. Data analysis will involve comparing the changes in cardiovascular health parameters between the two groups to determine the effects of HIIT on cardiovascular health outcomes. Statistical methods such as t-tests and analysis of variance (ANOVA) will be used to assess the significance of any observed differences. Additionally, subgroup analyses may be conducted to explore the effects of HIIT on different demographic groups or fitness levels within the study population. The findings of this research are expected to contribute to the growing body of evidence on the benefits of HIIT for cardiovascular health improvement, particularly in sedentary individuals. By elucidating the physiological mechanisms underlying the effects of HIIT on cardiovascular health, this study may inform the development of targeted exercise interventions for individuals at risk of cardiovascular diseases due to sedentary behavior. Ultimately, the research aims to promote the adoption of HIIT as a feasible and effective strategy to enhance cardiovascular health and reduce the burden of cardiovascular diseases in sedentary populations.
