Abstract in Portuguese
Uma das características dos adolescentes é a fase atrasada dos ritmos biológicos circadianos. Esse atraso na expressão da ritmicidade circadiana pode gerar um atrito entre o tempo biológico e o tempo social (horário escolar). Assim, analisamos a expressão do atrito temporal entre o tempo biológico e o tempo social em adolescentes escolares. Todos os adolescentes atrasaram os horários do inicio e do final do sono na comparação entre os dias letivos e não letivos. Os adolescentes atrasam a acrofase da temperatura periférica, e a MFS na comparação entre os dias letivos e não letivos. Foi observada uma diminuição significativa para os vespertinos, na ritmicidade circadiana da temperatura na transição dos dias letivos para os dias não letivos. Dessa forma, o deslocamento da acrofase da temperatura e o deslocamento da MFS podem ser a expressão do atrito temporal. Esse cronicidade do atrito pode trazer conseqüências negativas para o bem estar dos adolescentes.

Abstract in English
And one of the adolescents characteristics is the latest phase of circadian biological rhythms, compared with children and adults. This delay in the expression of circadian rhythmicity may generate friction between biological time and social time. Thus we analyzed the temporal friction between biological time and social time in scholar adolescents. All adolescents delay the time of beginning and the end of sleep in school days compared to non-school days. All adolescents had a delay in the peripheral temperature acrophase, and the MFS in the comparison between school days and non-school days. Therefore we understand the friction time between the biological and the social through changes in the CVS patterns, shift of peripheral temperature acrophase, and displacement of the MFS, in the transition from school days to non-school days. This chronicity of friction can have negative consequences for the well being of the adolescents.
