About this study
Cardiorespiratory fitness (CRF), which is a key marker of heart and lung health, can be improved through regular physical activity, particularly aerobic exercises. This project aims to evaluate the effects of aerobic exercises combined with low-intensity interval training (LIIT) on the cardiorespiratory fitness of school-going children. The increasing sedentary lifestyle among children has contributed to a decline in overall physical fitness and a rise in health-related issues.Cardiorespiratory fitness is crucial for overall health and can help reduce the risk of chronic diseases from a young age.

Cardiorespiratory fitness (CRF), which is a key marker of heart and lung health, can be improved through regular physical activity, particularly aerobic exercises. This project aims to evaluate the effects of aerobic exercises combined with low-intensity interval training (LIIT) on the cardiorespiratory fitness of school-going children. The increasing sedentary lifestyle among children has contributed to a decline in overall physical fitness and a rise in health-related issues.Cardiorespiratory fitness is crucial for overall health and can help reduce the risk of chronic diseases from a young age. The project will involve a structured program where children participate in either aerobic exercises, such as jogging or cycling, or low-intensity interval training, such as brisk walking with short breaks. Baseline measurements of heart rate, VO₂ max, 20 metter shuttle run test and endurance will be taken to assess each child's initial cardiorespiratory fitness level. The children will then undergo a 8 week training period, engaging in their assigned exercise regimen three times per week. Post intervention measurements will be recorded and compared to the baseline. This study will help determine if one type of training is more effective than the other in improving fitness levels among school-aged children, potentially guiding physical education curriculum and promoting healthier lifestyle habits from an early age.
The findings could contribute valuable insights into the role of exercise type on health outcomes, helping schools, parents, and health professionals make informed choices for children's physical activities to support optimal growth and long-term health improve heart rate , oxygen level , reduce cardio related disease.

What is being measured
The primary outcome is the main question the study is designed to answer.
20 metter shuttle run test
The 20-meter shuttle run test, also known as the beep test or PACER test. in schools to measure cardiovascular endurance in children. Here's how it's performed and measured:
Starting the Test:
Students line up at one end of the 20-meter track. An audio track, which plays a beep sound at set intervals, is used to signal when students should start running and reach the other line.
Running Pattern:
Students begin running at the sound of the first beep. They must reach the opposite line before the next beep sounds.Incease intensity faster.End test.
Measured: For one individual usaually lasts between 9-12 minutes
Secondary outcomes (1)
VO2 max
tests can be difficult to administer and are not suitable for all fitness levels. The quickest and easiest way to measure your VO2 max is to use a basic calculation or a walking/jogging test.
Determine your resting heart rate. Many fitness trackers and watches come with a heart rate monitor. If you have one of these, record your heart rate while at rest (sitting down, doing little-to-no physical activity). The best time to measure your 25 years old, your HRmax = 220 -25 = 195 beats per minute (bpm). There is some research that suggests this formula oversimplifies the calculation. You can also estimate your max heart rate with the formula HRmax = 205.8 - (0.685 x age) Define the simple VO2 max formula. The simplest formula to calculate VO2 max is VO2 max = 15 x (HRmax/HRrest). This method is considered to compare well with other common formulas. The units for VO2 max are milliliters of oxygen per kilogram of body weight per minute (mL/kg/min)
Measured: For one individual around 3-4 minutes required for performed
