Detailed explanation-1: -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-2: -Lactic Acid System: Carbohydrate Use Only The second energy system, the lactic acid (or glycolysis) system, supplies the additional energy for activities that last longer than 10 seconds and up to about 2 minutes.
Detailed explanation-3: -As the fastest way to resynthesize ATP, the phosphagen system is the predominant metabolic energy system used for all-out exercise lasting up to about 10 seconds. However, since there is a limited amount of stored CP and ATP in skeletal muscles, fatigue occurs rapidly.
Detailed explanation-4: -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.
