A runner in a cross country tournament experiences muscle cramps toward the end of the race. After completing the race and resting, the runner's cramps eventually go away. Which statement best explains what has occurred? The runner did not sufficiently warm up before the race and experienced cramping as the muscles were forced to convert fat into a useable energy source. As the runner reached the end of the race, fatigued muscle cells began to die at a rate faster than they could be replicated, which resulted in an increased amount of muscle cramping. As the runner became more fatigued, the muscles did not receive enough oxygen and were forced to perform anaerobic respiration, resulting in cramping. The runner did not consume sufficient levels of glucose before the race and experienced cramping because the muscles were forced to increase glucose production.
