Brief Summary

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.

Children, Only

Outcome Measures

Primary Outcomes (1)

• 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.

  For one individual usaually lasts between 9-12 minutes

Secondary Outcomes (1)

• VO2 max

  For one individual around 3-4 minutes required for performed

Study Arms (2)

Aerobic exercises

EXPERIMENTAL

Group in which performed all Group A will perform aerobic exercises. Aerobic exercises are ideal for improving cardiorespiratory fitness. Running or Jogging - Great for endurance and can be done in short sprints or long distances. Time 4min Rest 2 min 2 round Jump Rope - A fun way to build stamina and improve coordination. Time 2min Rest 2 min 2 round. Cycling - Strengthens the heart and lungs and is often enjoyable for kids. Time 5min Rest 1min rest Obstacle Courses - Running, jumping, crawling, and climbing for fun and fitness. Time 2min Rest; 1 min Dancing and Aerobic Games: Dance-based exercises or aerobic games (like tag or relay races) keep children engaged and provide cardiovascular benefits. Time. 2min Rest. 1 min Circuit Training- performed. Time. 3min Rest. 1min Stair climbing Time. 2 min Rest. 2min 2 round

Other: Aerobic exercise

Low interval Training Exercises

EXPERIMENTAL

Group 2 performed low interval training exercises.1)Brisk Walking and Arm Swings Time: 3 minutes of brisk walking Rest: 1 minute (slow walking or standing) Rounds: 3 rounds Duration: 12 minutes total 2. Step-Ups on a Low Platform or Bench Time: 2 minutes of step-ups (alternating legs) Rest: 1 minute Rounds: 3 rounds Duration: 9 minutes total 3)Low-Intensity Jump Rope Time: 1 minute of slow-paced jumping (or skipping in place if no rope is available) Rest: 1 minute Rounds: 4 rounds Duration: 8 minutes total 4. Side-to-Side Steps Time: 2 minutes of lateral steps (side-to-side motion with a slight squat) Rest: 1 minute Rounds: 3 rounds Duration: 9 minutes total

Other: Aerobic exercise

Model Details: The study will be randomized clinical trial. Find out two groups cardiorespiratory fitness level through two different protocoal exercises one is aerobic exercises and other is low interval training exercises. Baseline measurements of heart rate,l 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.
