A Study on the Effects of Muscle Membrane in Tension Development

On contraction of the muscles, marked changes in X-ray reflections are observed, suggesting that conformational changes of contractile molecules and the movement of myosin heads during muscle contraction. The time needed to the peak tension after the onset of stimulation and the amount of peak tension depend on the number of twitch cycle. It was found that the successive twitches decreased not only the time needed to the peak tension after the onset of stimulation but also the time needed to the maximum change of the X-ray intensity. However, the difference of the time between the peak tension and the maximum intensity change($T_{i}-I_{i}$ 수식 이미지) is nearly the same at any twitch. Based on these results the causes of the decrease of $T_{i}$ 수식 이미지 and $I_{i}$ 수식 이미지, and physiological implication of $T_{i}-I_{i}$ 수식 이미지 are discussed.
