Question

What does research suggest about regular physical activity's effect on the life span?

a) Consuming a healthful diet while engaging in regular physical activity can reduce oxidative stress without the need for Calorie restriction
b) Physical activity does not impact oxidative stress or Calorie restriction
c) Calorie restriction is the primary factor impacting oxidative stress and life span, not physical activity
d) Regular physical activity increases oxidative stress regardless of dietary habits

Answer 1

Regular physical activity reduces oxidative stress and is linked to increased longevity, supporting a combination of exercise and a healthy diet rather than solely relying on calorie restriction.

Step-by-step explanation:

Research suggests that regular physical activity has a positive impact on life span. It does this not only by reducing the risk of chronic diseases like heart disease, diabetes, and certain cancers, but also by reducing oxidative stress. This reduction in oxidative damage has been linked to increased longevity in various organisms. While calorie restriction has shown some potential in increasing lifespan due to lowered oxidative stress, its effectiveness in humans is not as clear. Thus, option (a) is correct, stating that engaging in regular physical activity along with a healthful diet can help reduce oxidative stress without the need for calorie restriction.
