A worker stands on their feet throughout most of the day and is beginning to experience cramping in their legs. They should walk around occasionally to increase the ______ in their legs.

• A. circulation
• B. strength
• C. flexibility
• D. temperature

Answer: (A)

Moving around increases circulation in the legs. Standing for long periods can let blood pool in the lower legs, which contributes to cramps. When you walk, the leg muscles act like pumps, squeezing the veins and helping blood return to the heart more efficiently. This boosts the delivery of oxygen and nutrients to the muscles and removes waste products, relieving cramps and fatigue. While walking can help overall fitness, the immediate benefit in this scenario is better blood flow, not a direct increase in strength, flexibility, or temperature.
