Final answer:
During a sprint, as ATP and creatine phosphate are quickly used, glycolysis becomes the main energy source by converting glucose to ATP for several minutes, due to insufficient oxygen for aerobic respiration.
Step-by-step explanation:
If you must sprint to escape your pursuers, glycolysis will generate the most ATP during a sprint lasting several minutes because after about 20 seconds of sprinting, the ATP and creatine phosphate (CP) stores in the muscle are rapidly depleted. Glycolysis then begins its work of converting glucose from blood or muscle glycogen into energy. Glycolysis can supply the energy needs at a high rate and has sufficient energy reserves to sustain an effort for several minutes, making it the primary energy-producing process during high-intensity, short-duration activities like sprinting. While glycolysis is not the system generating the most ATP overall (that's aerobic respiration), in the context of a several-minute sprint where oxygen delivery is insufficient, glycolysis is the predominant pathway.
