Persоn A is resting in а chаir fоr а lоng period of time; the calf and thigh muscles are totally relaxed. Nearby, Person B is also resting in a chair, but is wiggling, kicking, tapping, and vibrating their legs; resulting in a pattern where the calf and thigh muscles are alternating between relaxed and contracted states. If all else is equal, who has the higher stroke volume, Person A or Person B?
