Quizplus · Accepted Answer

Cross-country skiing and long-distance running are endurance sports that require continuous aerobic activity. Slow-twitch (Type I) fibers are better suited to this type of activity because they are highly resistant to fatigue and can sustain activity for long periods of time. Therefore, the skeletal muscles in the legs of competitive cross-country skiers and long-distance runners are likely to have more slow-twitch fibers.
