title: [Influence of muscular activity on muscle proteins and sarcoplasmic reticulum content and binding of Ca2+].
abstract: Training with an increase in intensity of loads causes muscle hypertrophy. The increase of myofibrillar proteins content and proteins of sarcoplasmic reticulum is greater after this training than after training with prolongation of duration of loads. The content of sarcoplasmic proteins is the same in the both kinds of training. The increase in the content of mitochondrial proteins is smaller. The myofibrillar and sarcoplasmic proteins content is the greatest with simultaneous increase in the intensity and duration of loads. Increase in the content of sarcoplasmic vesicles proteins in this case is the same as after training with an increase in the intensity of loads. An increase in the content of mitochondrial proteins is the same as in training with prolongation of duration of loads. The capacity of binding Ca2+ (per unit protein weight), Vmax and Km are not changed. When calculating per unit of muscle mass possibilities of Ca2+ binding under the effect of loads of the uncreasing intensity rise.
