Topic: “physiology”. The structure of the muscle fibers. Types and subtypes of muscle fibers. Muscle fibers — slow-twitch (MS) and fast-twitch (LH). The activity of aerobic, anaerobic enzymes. Similarities and
differences between male and female muscle fibres.
Structural and functional characteristics of motor units of the muscles. Muscle is an extremely heterogeneous tissue, composed mainly of muscle fibers, connective tissue, nervous and vascular elements, which together provide its main function — actively cuts. In the structure of muscle tissue there are two types of muscle fibers — slow-twitch (MS) and fast-twitch (LH). This division simplifies the tissue organization of the muscles, among which there are different kinds of muscles, due primarily to morphological and functional properties of their fibers. However, the selected Continue reading
How to quit Smoking
Ways to quit Smoking many. And quickly quit Smoking more moreover, almost every smoker, trying to quit Smoking crazes, supplements widely known or “branded” method of methods, techniques and practices. All for easy cast, facilitate this difficult period.

According to one version, the founders of this modern type of fitness became Finnish skiers. It appeared to be a few training sessions in the winter, and they began to walk in the summer, using ski poles to load the hands and the muscles of the upper torso. Those skiers who trained in the summer with the assistance of crutches, showed higher winter sports results. And those who ignored the summer training, was significantly inferior in performance to their more zealous colleagues.
This is one of the versions. Popular Nordic walking began in Europe in the 80-ies of the last century. Modern guru is considered Finn mark Cantana who first developed the semblance of instructions on the technique of Nordic walking. The work he published in 1997, and then by trial and error found the optimum design of sticks Continue reading
