Primarily the anaerobic glycolysis (the lactic acid) system.
Explanation: the ATP–PC (phosphagen) system fuels the first ~5–10 seconds, but for an all‑out effort lasting around 60 seconds the fast glycolytic (anaerobic lactic) pathway provides the majority of ATP. Aerobic metabolism begins contributing and increases with time, but it is not the dominant source during a steep one‑minute climb.
