title: [Physical state of adolescents with the high stress reactivity].
abstract: Research objective was studying of features of a physical state (PS) adolescents of 13-14 years with high (n = 97) and low (n = 85) level of stress reactivity. The obtained data testify that in puberty formation of mechanisms of energy supply for muscle activity at adolescents with various level of stress reactivity occurs heterochronic and nonlinearly. Thus hyperreactivity boys of 13-14 years are characterised concerning high anaerobic alactic and the low aerobic productivity of the organism raised by physiological working costs and slowed down restoration after loadings of the big and submaximum capacity. Specificity of physical readiness of hyperreactivity teenagers consists that at them the high level of development of speed and force is combined with rather low level of development of the general endurance. Intergroup distinctions concerning muscular working capacity and the impellent readiness, caused by stress reactivity, are shown at adolescents of 13-14 years at different stages of puberty (SP). Thus and hyper--and hyporeactivity boys with II and III SP, are characterised in comparison with children with IV SP higher indicators of aerobic productivity of an organism, against rather small anaerobic possibilities. Results of research give the basis to believe, that at hyporeactivity adolescents efficiency of functioning of mechanisms of antihypoxic protection is lowered.
