Thesis Abstract

Abstract
This thesis investigates the effects of high-intensity interval training (HIIT) on cardiovascular health in sedentary individuals. Sedentary lifestyles have been associated with an increased risk of cardiovascular diseases, making it imperative to explore effective exercise interventions such as HIIT to improve cardiovascular health. The study aims to contribute to the existing body of knowledge by examining the impact of HIIT on key cardiovascular parameters, including heart rate, blood pressure, and aerobic capacity, among sedentary individuals. The research methodology involved a randomized controlled trial with sedentary participants assigned to either a HIIT intervention group or a control group. The HIIT intervention consisted of structured exercise sessions involving short bursts of high-intensity exercise followed by periods of rest or low-intensity activity. The control group maintained their usual sedentary lifestyle throughout the study period. Chapter 2 provides a comprehensive literature review on the benefits of HIIT on cardiovascular health, highlighting previous studies that have demonstrated improvements in cardiovascular parameters following HIIT interventions. The review also examines the physiological mechanisms underlying the cardiovascular adaptations to HIIT, such as improved cardiac function, vascular health, and aerobic capacity. In Chapter 3, the research methodology is detailed, including participant recruitment, HIIT intervention protocols, data collection procedures, and outcome measures. The study design aimed to assess changes in cardiovascular parameters before and after the HIIT intervention, utilizing methods such as heart rate monitoring, blood pressure measurements, and maximal oxygen consumption (VO2 max) testing. Chapter 4 presents a thorough discussion of the findings, analyzing the impact of HIIT on cardiovascular health outcomes in sedentary individuals. The results indicate significant improvements in aerobic capacity, reduced resting heart rate, and lower blood pressure levels in the HIIT group compared to the control group. These findings support the efficacy of HIIT as a time-efficient and effective exercise intervention for enhancing cardiovascular health in sedentary individuals. Finally, Chapter 5 summarizes the key findings of the study and discusses the implications for clinical practice and future research. The study contributes valuable insights into the potential benefits of HIIT in improving cardiovascular health among sedentary individuals, emphasizing the importance of regular physical activity in reducing cardiovascular disease risk. Overall, this thesis underscores the importance of incorporating HIIT as a viable exercise strategy to promote cardiovascular health and overall well-being in sedentary populations.

Thesis Overview

Research Overview: Title: "The Effects of High-Intensity Interval Training on Cardiovascular Health in Sedentary Individuals" Introduction: Physical inactivity is a major risk factor for cardiovascular diseases, which are leading causes of mortality worldwide. Sedentary individuals are at a higher risk of developing cardiovascular health issues due to their lack of regular exercise. High-Intensity Interval Training (HIIT) has gained popularity as an effective form of exercise that can improve cardiovascular health in a time-efficient manner. This research aims to investigate the specific effects of HIIT on cardiovascular health in sedentary individuals. Background of the Study: The prevalence of sedentary lifestyles and associated cardiovascular diseases has become a significant public health concern globally. Traditional aerobic exercise has been shown to improve cardiovascular health, but HIIT offers a more time-efficient alternative with potential benefits. HIIT involves short bursts of intense exercise followed by brief recovery periods, challenging the cardiovascular system in a different way compared to steady-state exercise. Problem Statement: Despite the known benefits of regular exercise on cardiovascular health, sedentary individuals often struggle to adopt and maintain exercise routines. There is a need to explore alternative, time-efficient exercise strategies such as HIIT to improve cardiovascular health in this population. Understanding the specific effects of HIIT on cardiovascular health parameters in sedentary individuals can provide valuable insights for designing effective exercise interventions. Objectives of the Study: 1. To investigate the physiological responses to HIIT in sedentary individuals. 2. To assess the impact of HIIT on cardiovascular health markers such as blood pressure, heart rate, and lipid profile. 3. To evaluate the adherence and feasibility of HIIT in sedentary individuals. 4. To compare the effects of HIIT with traditional aerobic exercise on cardiovascular health outcomes. Limitations of the Study: This study may be limited by the sample size, duration of the intervention, and potential confounding variables such as diet and other lifestyle factors. Generalizability of the findings may also be limited to sedentary individuals without underlying medical conditions. Scope of the Study: The study will focus on sedentary individuals aged 18-50 years without pre-existing cardiovascular diseases. Participants will undergo a structured HIIT program under supervision to assess the effects on cardiovascular health parameters over a specified period. Significance of the Study: This research has the potential to contribute valuable insights into the effectiveness of HIIT as a time-efficient exercise intervention for improving cardiovascular health in sedentary individuals. Findings from this study may inform future exercise recommendations and public health strategies aimed at reducing cardiovascular disease risk in sedentary populations.
