Question

Janna used to go biking every other afternoon with her sister, but she had to stop this because she started an afterschool job. What consequence will Janna experience over time if she does not find a similar activity to replace the biking?

Answer 1

Answer:

Decrease in aerobic capacity

Explanation:

Aerobic capacity is a term used to describe a body's ability to transport and use the oxygen that is breathed and carried into the bloodstream. This capacity is strengthened with the practice of aerobic exercises, which are the type of physical activity that promotes the use of oxygen for the generation of energy in the muscles.

Cycling is an aerobic activity, so we can say that Janna had a high aerobic capacity, since she rode a bicycle every day. However, as Jana doesn't have time for this anymore, she will need to find an equivalent exercise if she doesn't want to have this reduced capacity.

Answer 2

The muscles that were used when riding the bike will shrink and become weak again if they do not continue being used.
