(a) Long distance runners run more slowly because lactic acid quickly builds up in their muscles and causes fatigue. Sprinters do not run for a
long enough for lactic acid to build up in their muscles.
(b) The large muscles of sprinters increases the oxygen supply to each muscle, preventing lactic acid from forming.
(c) Sprinters do not run for long enough for sufficient lactic acid to build up in their muscles; therefore they can have large muscles for more power. By being lighter and running more slowly, long distance runners ensure that their muscles receive enough oxygen for aerobic respiration.
(d) Sprinters run faster because their large muscles have more blood running through them to stop anaerobic respiration from taking place. Long distance runners run more slowly because they are using the energy from anaerobic respiration, which does not produce as much ATP as aerobic respiration.
