Types of physical activity, the intensity
Systematic physical activities lead to the adaptation of the human body to perform physical work. In the adaptation are changes in the muscle tissues and various organs as a result of training. All these changes determine the training effects. They are manifested in the improvement of various functions of the body and improving physical fitness.
In the analysis of the determinants of physical training effects of exercise, we can highlight the following aspects:
and functional effects of your workout;
– threshold, critical load for the occurrence of practice effects;
– the reversibility of training effects;
– specificity of training effects;
– treniruemoj, which determines the magnitude Continue reading
Muscle tissue and its adaptation to physical loads
Category: Scientific fitness Created: 09 April 2014
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
