An animated exploration of what really causes muscle fatigue during exercise. Going beyond the old myth of “lactic acid = soreness,” this lesson shows learners how factors like ion imbalances and energy depletion make muscles stop working. It builds understanding of exercise physiology: students learn why their arms burn after lifting weights or why they can’t sprint forever. Equipped with this knowledge, they can appreciate proper rest and nutrition in training. It’s an engaging science explanation that reinforces biology concepts in the context of fitness.
