After ballistic athletes complete training intervals for four consecutive training sessions without errors, they advance to next training interval stress levels. Pitching is a ballistic activity. Pitching training programs teach perfect pitching motor unit contraction and relaxation sequences. Thousands of perfect pitching technique hours create pitching engrams. Starting Stress Levels Training program designers must carefully control training interval stress levels.
Designers manipulate training intensities, resistance amount and repetition numbers.
Athletes generally start new exercises at one-half maximum intensities. However, untrained aerobic athletes' anaerobic thresholds are approximately forty percent maximum intensities. Therefore, aerobic athletes should not start aerobic training intervals at ten percent above anaerobic thresholds. Anaerobic and ballistic athletes have no difficulty starting training intervals at one-half maximum intensities. Some anaerobic and ballistic athletes may start training intervals at higher intensities.
