Which of the following statements regarding Canada's physical activity guidelines is false?

The statement regarding light effort being 30-45 minutes is incorrect. Canada's physical activity guidelines generally define light effort as activities that do not significantly raise the heart rate and include everyday movements. The recommendations for light physical activity typically suggest that individuals should aim for a greater duration, around 60 minutes or more, especially when it comes to fulfilling health benefits.

In contrast, the guidelines recognize moderate effort, which can fall within a range of 30 to 60 minutes, promoting a higher intensity of activity where individuals are breathing faster and have an elevated heart rate. Vigorous effort, on the other hand, is outlined as shorter durations of 20-30 minutes due to the higher intensity associated with such activities, which can lead to significant health benefits even when performed for shorter periods.

Understanding these classifications helps in creating effective fitness plans tailored to individual goals and capabilities, ensuring that time spent in physical activity is both meaningful and aligned with the guidelines for optimal health benefits.
