Different types of exercise can change how our bodies use energy in different ways. This mainly depends on the kind of activity, how hard we do it, and how long we keep it up.

Aerobic Exercise

• What it is: These are exercises that you can do at a low to moderate level, like running, cycling, and swimming.
• Energy Use: Your body mainly uses something called the oxidative system.
• Effects: Doing aerobic exercise can increase the number of tiny energy factories in your cells, called mitochondria, and helps your body burn fat better. Studies suggest that if you do this regularly, you might increase your resting metabolic rate (RMR) by about 10-15%.
• Calories Burned: In a 30-minute workout, you could burn around 300-400 calories, depending on how much you weigh.

Anaerobic Exercise

• What it is: These are high-intensity activities like weightlifting and sprinting.
• Energy Use: Your body mainly uses different systems called ATP-PCr and glycolytic systems.
• Effects: This type of exercise helps build muscle, which can raise your RMR by about 5-10% for every kilogram of muscle you gain.
• Calories Burned: When you do resistance training, you might burn about 200-300 calories in an hour. Plus, your body keeps using more oxygen for up to 24-48 hours afterward.

Conclusion

In simple terms, the type of exercise you do really matters for how your body burns energy. Aerobic exercises help you use fat better, while anaerobic exercises help build muscle and keep your metabolism high even after you finish working out. Knowing these differences can help you make better choices for your workouts and reach your health and fitness goals!
