Detailed explanation-1: -The ATP-PC System rebounds to over 85% in about 3 minutes and is completely replenished after 10 minutes. That’s why it’s important to take rest periods of at least 3 minutes in between these maximal output exercises.
Detailed explanation-2: -The system is rapidly replenished during recovery; in fact, it requires about 30 seconds to replenish about 70% of the phosphagens and 3 to 5 minutes to replenish 100%.
Detailed explanation-3: -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.
