Final answer:
Regular and moderate exercise, such as brisk walking, is beneficial for young adults. Exercise contributes to cardiovascular health through an increased heart rate which boosts the heart's stroke volume and cardiac output, which permits longer activity before fatigue. Sixty minutes of daily exercise is typically recommended. Long-term endurance training can alter gene expression in muscle tissues.
Step-by-step explanation:
When discussing optimal activity for young adults, there are several pieces of information that are crucial to stress:
- Moderately brisk walking is an appropriate aerobic exercise, providing beneficial cardiovascular health outcomes and helping prevent obesity.
- Exercise and physical activity will lead to an increase in heart rate, with the maximum heart rate in young adults typically being estimated by subtracting the person's age from 220.
- Regular exercise increases heart efficiency, by increasing both the heart's stroke volume and cardiac output, which allows for longer exercise duration before fatigue and reduced stress on the heart.
- Generally, 60 minutes of exercise daily is considered optimal. This moderate level of daily exercise is associated with improved cardiac function and overall cardiovascular health.
It's also valuable to note that prolonged endurance training can influence gene expression in muscle tissue, as per recent studies.
