Investigating the Effects of Exercise Intensity on Heart Rate Variability in Young Adults.

Thesis Abstract

Abstract
This thesis explores the impact of exercise intensity on heart rate variability (HRV) in young adults. The study aims to investigate how different levels of exercise intensity affect HRV, which is an important indicator of autonomic nervous system activity and overall cardiovascular health. The research is motivated by the growing interest in understanding the physiological responses to exercise and how they influence health outcomes. Chapter 1 provides an introduction to the topic, including the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of key terms. Chapter 2 consists of a comprehensive literature review that examines previous studies related to exercise intensity and HRV. Chapter 3 outlines the research methodology, including the study design, participant recruitment, data collection methods, and statistical analysis techniques. The findings presented in Chapter 4 reveal the effects of different exercise intensities on HRV parameters, such as time domain and frequency domain measures. The results demonstrate that high-intensity exercise leads to greater changes in HRV compared to moderate or low-intensity exercise. These findings have implications for exercise prescription and monitoring in young adults to optimize cardiovascular health and performance. In the concluding Chapter 5, the summary of the thesis highlights the key findings, implications for practice, recommendations for future research, and concluding remarks. This research contributes to the growing body of knowledge on the relationship between exercise intensity and HRV in young adults, shedding light on the physiological mechanisms underlying cardiovascular adaptation to exercise.
