Final answer:
RPE and cardiovascular endurance are important to consider when engaging in physical activity. Aerobic exercises improve cardiovascular health and muscular endurance, while regular exercise increases the efficiency of the heart. The recommended duration of vigorous aerobic activity is 60 minutes.
Step-by-step explanation:
When considering RPE (Rating of Perceived Exertion) and cardiovascular endurance, there are a few important things to keep in mind:
- Aerobic exercises: These exercises, like cycling, walking, and running, improve cardiovascular health and muscular endurance by causing the heart to beat faster and using oxygen to contract muscles.
- Cardiac reserve: Regular exercise increases the efficiency of the heart and its ability to pump blood. The difference between maximum and resting cardiac output is known as the cardiac reserve.
- 60 minutes of vigorous aerobic activity: This is the recommended duration to help keep the cardiovascular system healthy.
