exercise energy expenditure if influenced by which of the following variables
body composition exercise intensity height and weight training status
Exercise energy expenditure can be influenced by several variables, including:
1. Exercise intensity: The energy expenditure during exercise is directly proportional to the intensity of the exercise. Higher intensity exercises require more calories to be burned.
2. Exercise duration: The longer the exercise, the more energy expenditure is needed. Longer exercises require more calories to be burned, as the body needs to maintain sufficient energy levels to complete the activity.
3. Body weight: Heavier individuals expend more energy during exercise compared to lighter individuals because they have to move more mass. The rate of energy expenditure during physical activity is generally higher in people who weigh more.
4. Muscle mass: The amount of muscle mass one has can also affect energy expenditure during exercise. More muscle mass means more calories will be burned because muscles require more energy to function.
5. Age: As people age, their bodies tend to accumulate more fat and lose muscle. This can lead to a lower energy expenditure during exercise and may require adjustments to exercise intensity and duration to maintain the necessary calorie burn.
6. Fitness level: A more fit person will burn fewer calories for a given amount of exercise than a less fit person. This is because a fit person has a more efficient cardiovascular system and can better use oxygen to generate energy.
7. Gender: Men typically burn more calories than women because their bodies are larger and contain more muscle mass. Hormones can also play a role in energy expenditure during exercise, as testosterone promotes muscle growth and fat loss.
Overall, many variables influence exercise energy expenditure, and taking them into account can help individuals optimize their workouts and meet their fitness goals.
