Bowditch's effect: - Bowditch was a German physiologist. He put foh the term Treppe, which mean staircase. If you increase the frequency of a stimulus to a muscle, each succeeding contraction would be stronger than a preceding one. This effect has been c/a The staircase effect or Bowditch's effect. Increase frequency of stimulation results in increasing strength of contraction. Physiological basis for this effect is increased sarcoplasmic calcium. Strength of contraction of muscle [?] amount of sarcoplasmic calcium.
