AP BIOLOGY

Detailed explanation-1: -Plyometrics trains two anaerobic energy systems-the creatine phosphate system and the lactic acid system. The creatine phosphate system depends on energy stores that already exist in the muscles. Plyometric exercises that last a mere 4 to 15 seconds deplete the energy stores.

Detailed explanation-2: -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. There is also no acidic by-product, which usually causes fatigue.

Detailed explanation-3: -Training the ATP-PC energy system can be achieved by using short (3-10sec) high power demand physical activities followed by 1-3+ minutes of rest. The very high power demands require an extended period of rest to allow for the system to recharge.

Detailed explanation-4: -The ATP-PC system provides an immediate and intense short burst of energy, useful in sports such as 100m sprints, Powerlifting, or throwing events such as the Javelin, Shot Put, or Discus throw, but is only useful for around 10 seconds.

Detailed explanation-5: -The ATP-PC system and the anaerobic glycolytic system are both anaerobic systems, meaning that oxygen is not used by these systems to synthesise ATP. These systems are quicker at producing energy, however they do not last very long (they fatigue quickly).
