After the first 2.5 minutes Glycolysis follows ATP-PC (Adenosine Triphosphate (Phosphocreatine) ATP-PC system is the primary system behind very short powerful movements used for short durations of 10 seconds. The ATP-PC system does not produce any lactic acid or use oxygen it is an alactic anaerobic energy system. This system facilitates all short powerful movements, such as the average tennis rally that typically last about 5 to 10 seconds with 2 to 3 strokes per rally. To get a better understanding, “A rally in tennis is a collective name given to a sequence of back and forth shots between players, within a point. A rally starts with the serve and the return of the serve, followed by continuous return …show more content…
While there is some varieties and differences in rallies and in tennis for example the distance a player runs in a set or match depending on their style of game, some players may run 3 to 5 miles during a five-set match, and in some cases even more. The average rest period between rallies is about 15 seconds, but it gets shorter depending on the player’s style of play. There are three systems that continually function together to sustain muscle activity and restore energy to the body, also vo2 maximum oxygen intake is a major key in cardiovascular and aerobic capacity. The ATP-PC system is the primary system and the immediate source of energy, non-oxidative glycolysis (moderate power/short duration), and oxidative metabolism systems (low power/long duration) are two secondary sources for short and long powerful movements and all muscle contractions during the average rally set and or match. When training for tennis, it’s important to hydrate before and after to condition the body, in terms of energy sources and in relation to the ATP-PC systems dietary intake, replacing electrolytes and carbohydrates is essential but fats are also utilized energy sources. Krebs Cycle Electron Transport Chain (ETC) produces majority of ATP during Aerobic Metabolism, aerobic metabolism is the creation of energy by the consumption of fats, amino acids and
