With properly designed stress level increases, aerobic athletes' anaerobic thresholds steadily increase. Pitchers do not train aerobically. Nevertheless, pitching training programs should end with aerobic training because aerobic training metabolizes lactic acid accumulations. Eliminating lactic acid accumulations reduce training stiffness and soreness. Anaerobic For anaerobic competitions, training program designers maximize training interval intensities.
Athletes perform increasing repetition numbers over increasing time periods.
During early training intervals, anaerobic athletes master perfect motor unit techniques. After athletes perfect techniques, they start anaerobic training intervals. Anaerobic muscular systems function normally at higher lactic acid accumulations. After anaerobic athletes training intervals for four consecutive training sessions without distress, they advance to next training interval stress levels. Pitchers do not train anaerobically.
