Answer :
When you are engaged in heavy activity such as a sprint, your muscles will get most of their energy from glycolysis. This is when the glucose in your body is broken down to use in anaerobic respiration to aid muscles when there is no oxygen available at the time.
Answer:
The most appropriate answer should be fermentation.
Sprint refers to the high-intensity exercise in which an athlete runs at his or her full speed for a short period of time.
Due to high intensity, the oxygen level decreases in the muscles and they undergo lactic acid fermentation.
It results in the depletion of glycogen reserve in the muscles as glucose is being used in the fermentation in order to provide energy.
Due to the build of lactic acid in the muscle, the athlete would feel burning effect and cramps in the muscles.
It decreases the performance of the athlete after sometimes.
