Detailed explanation-1: -The ATP-PC System lasts for 6-10 seconds and is used during maximal power output exercises such as all-out effort sprints, jumps, 1RMs etc. It’s the simplest energy production process, as it enables a fast muscle contraction.
Detailed explanation-2: -Duration that the system can operate – The alactacid energy system (ATP/PC) does not last very long due to the limited fuel source and fast ATP production. The alactacid system will deplete its fuel in 8 seconds when used at maximal intensity, but can take as long as 12 seconds if used at a lower intensity.
Detailed explanation-3: -The anaerobic energy system (also called the lactic acid system) is the body’s way of creating energy in the form of ATP quickly. Primarily using glucose as fuel, this energy system powers the muscles anywhere from ten to thirty seconds for intense efforts.
