Discuss the variations in foot shape and the type of shoes that are required for each foot shape

Different sizes need different shoes.

The type of shoes one purchases should depend on the person's foot shape. There are three variations: normal, flat-footed, and high arches. Those with high arches tend to roll their foot outward while running. Shoes with more cushioning and flexibility are required in this case. People who are flat-footed roll their foot inward; this movement demands a shoe that provides more stability. People who have normal-shaped feet can choose just about any shoe because most shoes are designed to fit this type.

Explanation:

the more fit you are, the faster the recovery. your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal. this “recovery heart rate” is measured as part of an exercise stress test.
