Studies have been made on temporal characteristics of contraction and Mg-ATPase activity of the sarcoplasmic reticulum in various phasic and tonic muscles of the frog. The time of isometric tetanic contraction and Mg-ATPase activity of the reticulum in the phasic m. sartorius and the tonic m. coracoradialis are correlated. The data obtained suggest that the duration of twitch isometric contraction is related to calcium content of muscles.
对青蛙不同的相性和紧张性肌肉中肌浆网收缩的时间特性和镁 - 三磷酸腺苷酶活性进行了研究。相性的缝匠肌和紧张性的喙肱肌中，等长强直收缩时间与肌浆网的镁 - 三磷酸腺苷酶活性相关。所获得的数据表明，单收缩等长收缩的持续时间与肌肉中的钙含量有关。
