Detailed explanation-1: -The anaerobic glycolysis (lactic acid) system is dominant from about 10–30 seconds during a maximal effort. It replenishes very quickly over this period and produces 2 ATP molecules per glucose molecule, or about 5% of glucose’s energy potential (38 ATP molecules).
Detailed explanation-2: -Anaerobic Lactic (Glycolytic) Energy System (High to Medium Intensity – Uptempo) The anaerobic lactic (AL) system (also known as fast glycolysis) provides energy for medium to high-intensity bursts of activity that lasts from 10 seconds to a max of approximately 90 seconds.
Detailed explanation-3: -Sprint repeats – 10 repetitions of 30 second sprints as fast as possible with 15 seconds recovery between each sprint (2:1 ratio)
