ADP (adenosine diphospate) results when the terminal phospate molecule is cleaved from ATP.
Anaerobic exercise is short-lasting, high-intensity activity, where your body's demand for oxygen exceeds the oxygen supply available. Anaerobic exercise relies on energy sources that are stored in the muscles
ATP (Adenosine Triphosphate) is manufactured when glucose (sugar) is broken down to lactic acid. High-intensity efforts requiring 1 to 3 minutes before energy (ATP) is primarily drawn from this system. More commonly referred to as anaerobic glycolysis.
Biomechanics - The sport science field that applies the laws of mechanics and physics to human performance.
CPK (creatine phosphokinase) an enxyme which reacts with ADP to form ATP. During short, high intensity contractions, CP serves as the major source of energy. This form of energy generation is often called alactic anaerobic because it neither produces lactate nor requires oxygen. It is of paramount importance in sports requiring bursts of speed or power such as sprints of 10 seconds or less in duration.
Sarcomere - The functional unit of a muscle and is made of actin and myosin. Actin and myosin will slide the actin closer together causing the sacromere to contract. When myosin first binds to actin it has ADP attached to it. It then pulls the actin down by releasing the ADP.
