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
Five great ways to improve sports performance and improve body composition using coffee
As you know, coffee consumption has many positive health effects. For example, it is associated with a decreased risk of death, development of cancer, cardiovascular disease, diabetes, and metabolic syndrome. However, in addition to caffeinated coffee is also useful to improve athletic performance.
During controlled clinical studies have found that caffeine improved performance by 25 percent, which corresponds to approximately five to seven percent increase in reality, for example, in the competition. Coffee significantly speeds up recovery and enhances motivation to workout. Thus, most people can extract from coffee many Continue reading
