They don't, theyy use the ATP-PC system, which lasts for around 10 seconds. This is because it is an explosive event which is what the attrirbrutes of the ATP-PC are designed for.
teachpe.com has alot about energy systems,
hope this helps
A 100m sprinter primarily relies on the anaerobic energy system, specifically the ATP-PCr (adenosine triphosphate-phosphocreatine) pathway, during the short, explosive duration of the race. This system provides immediate energy for high-intensity efforts lasting up to about 10 seconds, allowing the sprinter to accelerate rapidly and maintain peak speed. Since the 100m sprint is a high-intensity activity, it does not allow sufficient time for aerobic metabolism to contribute significantly. As a result, the sprinter's performance depends heavily on the rapid breakdown of stored energy in the muscles without the need for oxygen.
Rugby match
A sprinter would be using aerobic respiration. Running requires large quantities of oxygen, and is used up quickly to produce energy.EDIT: Actually, a sprinter would be more likely to use anaerobic respiration, if compared to someone else, such as a marathon runner.A marathon runner would rely on aerobic respiration and efficient use of the oxygen they breathe, whereas a sprinter would use up all that energy very fast, which would then lead to a lack of oxygen, which finally results in the usage of anaerobic respiration to attempt to fulfill the large amount of energy required to go so fast.
so they can breath :)
Anaerobic
I believe it is the ATP/CP system (adenosine triphosphate/ creatine phospahte) and towards the end they go into their lactic acid system because the first system only lasts for up to 8 seconds-ish. Sorry if I've got something wrong but that's what i think it is, i remember it vaguely from GCSE. Hope this help :)
The anaerobic system is a metabolic pathway that provides energy to muscles during high-intensity activities when oxygen availability is limited. It involves the breakdown of glucose without the use of oxygen to produce energy quickly, resulting in the accumulation of lactic acid as a byproduct.

In handball, a winger primarily utilizes the anaerobic energy system, specifically the ATP-PCr (adenosine triphosphate-phosphocreatine) system and anaerobic glycolysis. These systems provide quick bursts of energy needed for sprints, jumps, and rapid changes in direction during gameplay. Additionally, due to the high-intensity nature of the sport, aerobic energy may also play a role during longer periods of sustained activity.
The use of nitrate or sulfate to produce cellular energy is an example of anaerobic respiration. In contrast to aerobic respiration which requires oxygen, anaerobic respiration utilizes alternative electron acceptors like nitrate or sulfate to generate energy in the absence of oxygen.
