Final answer:
During the Wingate test, the phosphagen system is the main contributor in the first 10 seconds, followed by an increasing reliance on glycolysis from 0-20 seconds, and performance is limited by energy depletion and fatigue as the test progresses to 30 seconds.
Step-by-step explanation:
The energy system that contributes to the ability to perform the Wingate test, which is a measure of anaerobic power, primarily involves the phosphagen system during the first 10 seconds. Bioenergetically, this system provides the quickest available energy through the breakdown of ATP and creatine phosphate but is rapidly depleted, limiting performance in the initial phase. From 0-20 seconds, there is a gradual shift where the glycolytic system starts to contribute more significantly as stored ATP and creatine phosphate are used up. Glycolysis can generate ATP relatively quickly but produces metabolic byproducts like lactic acid that contribute to muscle fatigue. Thus, glycolytic energy contributes to performance limitation during this phase. From 0 to 30 seconds, continued reliance on glycolysis coupled with the onset of lactic acid accumulation and a drop in phosphagen availability increasingly limits performance, as the body cannot sustain high-intensity output due to energy depletion and fatigue.
