Thesis Abstract

Abstract
Physical inactivity and sedentary lifestyles are major health concerns globally, contributing to the prevalence of cardiovascular diseases and other health-related issues. High-Intensity Interval Training (HIIT) has gained popularity as an effective exercise modality for improving cardiorespiratory fitness in various populations. This thesis aimed to investigate the effects of HIIT on cardiorespiratory fitness in sedentary individuals. Chapter one provides an introduction to the study, discussing the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. Chapter two presents a comprehensive literature review, exploring ten key studies on HIIT and its impact on cardiorespiratory fitness in sedentary populations. Chapter three details the research methodology, including the study design, participant recruitment, HIIT protocol, outcome measures, data collection procedures, and statistical analysis methods. The sample size, inclusion criteria, and ethical considerations are also discussed in this chapter. Chapter four presents the findings of the study, analyzing the effects of HIIT on cardiorespiratory fitness parameters such as VO2 max, heart rate, and respiratory rate. The results are discussed in relation to existing literature, highlighting the effectiveness of HIIT in improving cardiorespiratory fitness in sedentary individuals. Finally, chapter five provides a conclusion and summary of the thesis, emphasizing the key findings, implications for practice, and recommendations for future research. The study contributes to the growing body of evidence supporting the use of HIIT as a time-efficient and effective exercise strategy for enhancing cardiorespiratory fitness in sedentary individuals. Overall, this thesis sheds light on the potential benefits of HIIT as a promising intervention for promoting physical activity and improving health outcomes among sedentary individuals. Further research is warranted to explore the long-term effects and sustainability of HIIT programs in sedentary populations.

Thesis Overview

Research Overview: Title: "The Effects of High-Intensity Interval Training on Cardiorespiratory Fitness in Sedentary Individuals" Introduction: Regular physical activity is crucial for maintaining optimal health and preventing chronic diseases. However, many individuals lead sedentary lifestyles, which can have detrimental effects on their cardiorespiratory fitness. High-Intensity Interval Training (HIIT) is a popular exercise regimen known for its time efficiency and effectiveness in improving fitness levels. This research aims to investigate the specific effects of HIIT on cardiorespiratory fitness in sedentary individuals. Background of Study: The prevalence of sedentary behavior has increased globally, leading to a rise in health problems related to poor fitness levels. Cardiorespiratory fitness, a key indicator of overall health, is greatly influenced by physical activity levels. HIIT involves short bursts of intense exercise followed by brief periods of rest or lower-intensity activity. Studies have shown that HIIT can produce significant improvements in cardiorespiratory fitness in various populations, but its effects on sedentary individuals are not yet fully understood. Problem Statement: The sedentary lifestyle adopted by many individuals poses a significant risk to their cardiorespiratory fitness and overall health. Understanding the potential benefits of HIIT in this population is essential for developing effective interventions to improve fitness levels and reduce the risk of chronic diseases. Objectives of Study: 1. To assess the current cardiorespiratory fitness levels of sedentary individuals. 2. To investigate the effects of a structured HIIT program on cardiorespiratory fitness in sedentary individuals. 3. To compare the outcomes of HIIT training with traditional moderate-intensity continuous training. 4. To explore the feasibility and sustainability of incorporating HIIT into the routine of sedentary individuals. Limitations of Study: This research may face limitations related to the small sample size, participant adherence to the HIIT program, and the duration of the intervention. External factors such as diet, lifestyle habits, and genetic predispositions could also impact the study outcomes. Scope of Study: The study will focus on sedentary individuals aged 18-60 years with no prior experience in structured exercise programs. The HIIT intervention will be supervised and tailored to individual fitness levels to ensure safety and effectiveness. Significance of Study: This research will contribute to the existing body of knowledge on the benefits of HIIT for sedentary individuals. The findings may help healthcare professionals, fitness trainers, and policymakers in designing targeted interventions to promote physical activity and improve cardiorespiratory fitness in sedentary populations.
