ATP and Muscular Fatigue
When an athlete becomes fatigued, performance suffers. Everyone knows this is true, but why does it happen?
Muscular fatigue is caused by a decrease in muscular contractibility, or the muscle’s ability to respond rapidly to a stimulating agent telling the muscle to contract. That stimulating agent is calcium.
Unfortunately, exercise depletes calcium from muscle cells, causing a decrease in the strength of muscle contractions and therefore an increase in fatigue. In fact, a 50% decrease in calcium can result in an 80% reduction in force.1
The key to fighting muscular fatigue is to increase muscular function. Increases in muscular function can therefore lead to an increase in the intensity of muscle contractions.
