Thus, an MMA fighter must have high aerobic as well as anaerobic potential (phosphagenic and glycolytic energy system) both of the upper and lower limbs [2,4,5].
The results suggest that in table tennis matches the aerobic system provides the principal output energy, but the phosphagenic system (anaerobic alactic system) is the most important during periods of exertion.
Athletes of African descent have a higher percentage of fast-twitch muscle fibres, greater activity in the glycolytic, phosphagenic, and lactate dehydrogenase metabolic pathways, and greater rate of ventilation [1].
Overall, the aerobic system is the predominant mechanism of resynthesis of energy (ATP) in these sports, but in effort periods the phosphagenic system (ATP-PCr) is the main mechanism to resynthesis of ATP (Zagatto et al., 2008).
The intense efforts use phosphagenic energy sources (ATP;PCr) as the main mechanism to resynthesize energy (ATP) in contrast, during periods of rest, the aerobic energy supply dominates.
Measurement of anaerobic parameters in athletes is extremely important, especially in sports where there is greater participation from glycolytic and phosphagenic energy sources during periods of intense effort, as in the case of table tennis (Zagatto, 2004) and other sports where athletes are required to possess a high anaerobic capacity.
