## What is the difference between aerobic respiration and anaerobic respiration? Aerobic respiration takes place in the presence of air or oxygen while anaerobic respiration takes place in the absence of air or oxygen. The exchange of gases does not take place. ### Anaerobic activities * Involves quick burst of energy and are performed at maximum effort for a short time. * Any activity that breaks down glucose for energy without using oxygen. * Generally, these activities are of short length with high intensity. The idea is that a lot of energy is released within a small period of time, and the oxygen demand surpasses the oxygen supply. * Reference: [https://www.physio-pedia.com](https://www.physio-pedia.com) ### Anaerobic activities Example: sprinting, weightlifting, jump rope, rowing, squats, push-ups, squat jump, plyometrics, jumping jack, box jump, bicycle crunches, crunches, jumping lunges, pull-up, bench press, medicine ball throw, isometric exercise, jumping, plyometric training, jumping or jumping rope. ### Bone strengthening activities * Bone growth is stimulated by physical stress brought about by physical activity. As skeletal muscles contract, they pull their attachment on bones causing physical stress. This consequently stimulates bone tissues, making it stronger and thicker. Such bone strengthening activities can increase density throughout our skeletal system. This is called bone hypertrophy. * Example: running, skipping rope, and playing basketball can make our bones fit. ### Muscle strengthening activities * Exercises in which groups of muscles work or hold against a force or some weight. * Help build good muscle strength. When muscles do more work, it becomes stronger. Therefore, having strong and healthy muscles enable us to perform everyday physical task. * Example: push-ups, sit-ups, squats, and lifting. ### Guidelines for aerobic exercise 1. **Frequency** Always consider the number of aerobic exercise sessions per week. When doing cardio exercise, especially to lose weight, frequency is an important factor to make it more effective.
