What happens inside your body when you exercise?

Summary

Regular physical activity significantly reduces the risk of heart and circulatory diseases by 35%. Exercise boosts heart strength, enhances lung capacity, and increases oxygen delivery to muscles, making activity feel easier over time. It's especially beneficial for individuals with type 2 diabetes, as it improves insulin utilization and glucose absorption. Long-term exercise improves memory, lowers resting heart rate and blood pressure, and releases endorphins that enhance mood and reduce stress. Combining physical activity with a balanced diet helps maintain a healthy weight, with a recommended goal of 150 minutes of moderate-intensity activity each week.

Q & A

How much can regular physical activity lower the risk of heart and circulatory diseases?

Regular physical activity can lower the risk of heart and circulatory diseases by 35 percent.

What happens to your heart when you engage in physical activity?

When you are active, your heart beats faster and pumps more blood to the muscles being used, leading to a stronger and bigger heart over time.

Why do muscles require more oxygen during physical activity?

Muscles work harder during physical activity and need more oxygen to sustain their increased activity levels, leading to faster breathing and improved oxygen delivery from the lungs.

What is the benefit of increased capillaries in muscles due to regular activity?

Increased capillaries in the muscles improve blood flow and oxygen delivery, making physical activity feel easier over time.

How does physical activity benefit people with type 2 diabetes?

Physical activity helps individuals with type 2 diabetes by improving their cells' ability to use glucose, even without sufficient insulin, thus managing blood glucose levels.

What effect does regular physical activity have on memory and attention span?

Regular physical activity can enhance memory and attention span by stimulating growth in the brain areas involved in memory and learning.

What are the cardiovascular benefits of long-term physical activity?

Long-term physical activity can lead to a lower resting heart rate and lower blood pressure, which helps reduce the risk of heart and circulatory diseases.

How do endorphins produced during physical activity affect mood?

Endorphins are chemicals produced by the brain during physical activity that reduce feelings of pain and promote a more positive mood.

What is the relationship between physical activity and stress hormones?

Engaging in physical activity helps cut down on stress hormones, thereby reducing anxiety.

What is the recommended amount of moderate-intensity physical activity per week?

The recommendation is to aim for 150 minutes of moderate-intensity activity per week, with an emphasis on being active every day, even in 10-minute increments.
