Answer:
The answer is A. 2 min. sprint.
A 2-minute sprint requires the highest level of cardiorespiratory endurance because it is a high-intensity activity that requires the body to use a lot of oxygen. The other activities are lower-intensity activities that do not require as much oxygen.
Cardiorespiratory endurance is the ability of the heart and lungs to deliver oxygen to working muscles during continuous physical activity. It is an important component of physical fitness and is associated with a number of health benefits, including a reduced risk of heart disease, stroke, and diabetes.
There are a number of ways to improve cardiorespiratory endurance, including aerobic exercise, such as running, swimming, and cycling. Aerobic exercise is any type of exercise that raises your heart rate and makes you breathe harder. It is important to start slowly and gradually increase the intensity of your workouts over time.
In addition to aerobic exercise, there are a number of other things you can do to improve your cardiorespiratory endurance, including:
* Eat a healthy diet.
* Get enough sleep.
* Manage stress.
* Avoid smoking.
