Project Abstract

Abstract
High-intensity interval training (HIIT) has gained popularity in recent years as an effective exercise modality for improving cardiorespiratory fitness. This randomized controlled trial aimed to investigate the impact of HIIT on cardiorespiratory fitness in young adults. The study included a total of 100 participants aged 18-30 years, who were randomly assigned to either the HIIT group or the control group. The HIIT group underwent a 6-week intervention consisting of high-intensity interval training sessions, while the control group maintained their regular physical activity routine. The research design incorporated pre- and post-intervention assessments of cardiorespiratory fitness using standardized protocols such as VO2 max testing and heart rate monitoring during exercise. Additionally, perceived exertion levels, body composition measurements, and blood pressure readings were also recorded at baseline and after the intervention period. Data analysis involved statistical comparison of outcomes between the HIIT and control groups to evaluate the effectiveness of HIIT in improving cardiorespiratory fitness. The results indicated a significant improvement in cardiorespiratory fitness parameters among participants in the HIIT group compared to the control group. Specifically, the HIIT group demonstrated a higher increase in VO2 max, lower resting heart rate, and improved exercise tolerance. Moreover, subjective feedback from participants highlighted the perceived benefits of HIIT in enhancing overall fitness levels and motivation for physical activity. This study contributes to the existing literature by providing empirical evidence of the positive impact of HIIT on cardiorespiratory fitness in young adults. The findings underscore the importance of incorporating HIIT as a time-efficient and effective exercise strategy for improving cardiovascular health and fitness outcomes. Future research could explore the long-term sustainability and adherence to HIIT programs among different populations to optimize health benefits and promote healthy lifestyle habits. In conclusion, this randomized controlled trial supports the efficacy of HIIT in enhancing cardiorespiratory fitness in young adults and highlights the potential of this training modality as a valuable tool for promoting overall health and well-being. Implementation of HIIT programs in fitness and wellness settings could offer individuals a practical and efficient approach to achieving cardiovascular fitness goals and maintaining a healthy lifestyle.
