Thesis Abstract

Abstract
This thesis investigates the effects of High-Intensity Interval Training (HIIT) on cardiorespiratory fitness in sedentary individuals. Sedentary lifestyles are increasingly prevalent in modern society and are associated with numerous health risks, including reduced cardiorespiratory fitness. HIIT has emerged as a time-efficient and effective exercise modality that may offer a promising solution to improve cardiorespiratory fitness in this population. The primary objective of this study is to evaluate the impact of a structured HIIT program on cardiorespiratory fitness parameters, such as VO2 max, heart rate variability, and aerobic capacity, among sedentary individuals. Chapter 1 provides an introduction to the topic, outlining the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter 2 presents a comprehensive literature review covering ten key studies related to HIIT, sedentary behavior, cardiorespiratory fitness, and exercise interventions in similar populations. Chapter 3 details the research methodology, including study design, participant selection criteria, HIIT intervention protocols, outcome measures, data collection procedures, and statistical analysis methods. The chapter also discusses ethical considerations, potential biases, and limitations of the study design. In Chapter 4, the findings of the study are presented and analyzed in detail. Results related to changes in cardiorespiratory fitness parameters following the HIIT intervention are discussed, along with any significant trends or correlations observed. The discussion also explores the implications of the findings in the context of existing literature and potential practical applications for promoting physical activity among sedentary individuals. Finally, Chapter 5 offers a comprehensive conclusion and summary of the thesis, highlighting the key findings, implications, limitations, and recommendations for future research. The study contributes to the growing body of evidence supporting the efficacy of HIIT as an effective intervention for improving cardiorespiratory fitness in sedentary individuals. The findings have important implications for public health initiatives aimed at reducing sedentary behavior and promoting regular exercise to enhance overall health and well-being.
