Abstract

У статті розглядається питання розвитку фізичних якостей борців на початковому етапі тренувальної діяльності. Охарактеризовано особливості організаційно-методичних основи розвитку і вдосконалення якісних параметрів рухової діяльності борців.

The article deals with the development of physical qualities of fighters at the initial stage of training activity. Characterized the peculiarities of the organizational and methodological basis for the development and improvement of qualitative parameters of motor activity of fighters. Power is the ability of a person to overcome external resistance or to oppose him through muscular effort. From a physiological point of view - muscle strength is characterized by their ability to maximize stress in isometric mode. Distinguish absolute and relative strength. Absolute force - the ability of man to overcome the greatest resistance or counteract it in an arbitrary muscular tension. Relative strength is a force man exhibits at the rate of 1 kg of his own weight. In the process of ontogeny, the development of force is discrete and not linear in nature, has its recessions and upsets: faster developing muscles responsible for motility and posture, more slowly - small muscle groups. Distinguish dynamic and static strength. The dynamic force is associated with the execution of sub-maximal power of 10-20 s with the displacement of its own body or encumbrance at the level of 60-80% of absolute force. The variegatedness of dynamic force is the speed force - the ability of the neuromuscular system to mobilize the functional potential to achieve high levels of power in the shortest possible time. Static power is manifested in slow motion or in static efforts to overcome the maximum resistance and maintain the same burden. In the first case, the muscles operate in myometric mode, in the second - in isometric (without noticeable reduction). During these muscular tensions, these regimens tend to converge. Power depends on many biological factors: the physiological width of the muscles; the ratio of fast and slow muscle fibers; level of excitation of the corresponding nerve centers; contractile properties of muscles.
