Question

Quizplus · Accepted Answer

Distance swimming and distance running are endurance activities that require sustained muscle contractions over extended periods of time. These activities are most likely to stimulate the development of slow fatigue-resistant muscle fibers, also known as type I fibers. Type I fibers are highly aerobic and efficient at using oxygen to produce energy, making them well-suited for endurance activities.
