During a hammer throw, which energy sources provide the energy required for the movement?

Explanation:
Explosive, short-duration actions rely on immediate energy sources. The hammer throw lasts only a few seconds, so the muscles use stored ATP for instant energy. As the effort continues, the ATP-PC (phosphocreatine) system rapidly regenerates ATP to keep power available without oxygen. The lactic acid system, which comes into play with longer high-intensity efforts and lactate production, isn’t the primary source for a single throw. So the energy for a hammer throw comes from both stored ATP and the ATP-PC system.
