Cardiovascular Diseases, High-Intensity Interval Training, Sedentary Lifestyle, Young Adults



This study aimed to investigate the potential of High-Intensity Interval Training (HIIT) as a non-pharmacological intervention to reduce the risk of cardiovascular disease in a specific population.


A quasi-experimental design was employed; involving 20 young adults aged 25-30 recruited from a fitness centre. The participants underwent an 8 weeks high-intensity exercise program consisting of 3 weekly sessions. Baseline measurements of body mass, height, BMI, cholesterol, triglycerides, LDL, and HDL levels were taken before the intervention. Post-intervention measurements were obtained at the end of the 8 weeks.


The results demonstrated significant improvements in various parameters following the 8 weeks workout program. BMI decreased from 32.2±1.42 to 31.67±1.45, while cholesterol levels decreased from 221.37±9.3 to 201±9.64, indicating a reduction in total cholesterol. Triglyceride levels decreased from 181.5±10.98 to 170.1±11.93. LDL values decreased from 144.5±8.9 to 134.2±8.13, indicating a decrease in low-density lipoprotein. Additionally, HDL levels increased from 36.53±4.53 to 46±5.44, reflecting an increase in high-density lipoprotein levels. All these changes were statistically significant (p≤0.005).                                                     


The findings suggest that HIIT is an efficient and effective exercise for sedentary and inactive young males. The study supports using HIIT as a non-pharmacological approach to improve physical well-being, enhance fitness, and reduce the risk of cardiovascular diseases. HIIT provides a time- and cost-efficient alternative for individuals with limited exercise time who still desire optimal health and fitness outcomes.
