Answer:
Fuel sources for muscle contraction. A 100-meter sprint is powered by stored ATP, creatine phosphate, and anaerobic glycolysis of muscle glycogen. The conversion of muscle glycogen into lactate can generate a good deal more ATP, but the rate is slower than that of phosphoryl-group transfer from creatine phosphate
Explanation:
During a 100 meter dash, the primary sources of energy is creatine phosphate or PCr and glycogen.
The sources of energy during a 100 meter dash:
Both the glycogen and PCr are used as a source of fuel during the 100-meter dash or sprint. In the muscles of the leg, there is enough PCr to provide half the ATP required for the race. The other half of the energy needed is provided by the glycogen.
In a 100 meter sprint, only 1 to 2 seconds is used for the rate of glycolysis to enhance at the required factor to atleast 1000. Therefore, during the first two seconds, the hydrolysis of PCr contributes to the majority of ATP production, while glycolysis attains its maximal rate.
It has been shown that maximal sprinting performance is attained via the simultaneous use of glycogen and PCr.
Thus, the primary sources of energy during a 100 meter dash is glycogen and PCr.
