Comparing Aerobic Exercises and Low-Intensity Interval Training to Improve Heart and Lung Fitness in Boys Aged 6 to 12

What this Trial Is About

Researchers are evaluating how aerobic exercises combined with low-intensity interval training LIIT affect the cardiorespiratory fitness of school-aged children. This study focuses on children aged 6 to 12 years and aims to address the decline in physical fitness due to sedentary lifestyles. Improving cardiorespiratory fitness is important for overall health and may help reduce the risk of chronic diseases from an early age. Children will participate in either aerobic exercises like running, jogging, jump rope, cycling, dancing, and circuit training, or low-intensity interval training exercises including brisk walking, step-ups, low-intensity jump rope, and side-to-side steps. The program lasts 8 weeks with exercise sessions three times per week. Each group follows a structured routine with specific times and rest periods for each activity. Participants will have baseline measurements of heart rate, VO2 max, a 20-meter shuttle run test, and endurance assessed before starting the program. After the 8-week training, these tests will be repeated to compare changes. Researchers will monitor fitness improvements and heart and lung health indicators throughout the study. The main outcome measure is the 20-meter shuttle run test, which usually lasts 9 to 12 minutes for each child.
