Resumo

Introdução: O transporte de mochilas escolares pesadas foi reconhecido como uma fonte comum de stress biomecânico nas crianças. O antepé, que atua como o principal ponto de propulsão durante a marcha, experimenta frequentemente as pressões mais elevadas. Os adolescentes podem ser particularmente vulneráveis ​​devido ao desenvolvimento músculo-esquelético durante o curso e à menor tolerância à carga durante o crescimento.

Objectivo: Avaliar os efeitos de cargas seleccionadas de mochilas e de diferentes durações de marcha na pressão máxima na antevisão em adolescentes raparigas que frequentam a escola, utilizando um projecto de medidas repetidas.

Metodologia: Sessenta e novas crianças dos 10 aos 16 anos participação em estúdio. A pressão máxima da antena é registada através de um sistema de plataforma de pressão sob seis cargas selecionadas de mochila e sete durações de marcha. Se realizaram estatísticas descritivas e uma análise de medidas repetidas para examinar os efeitos da carga, o tempo e o lado da torta.

Resultados: A carga da mochila teve um efeito estatístico significativo na pressão máxima do ecrã, e verificou-se uma interação significativa entre a carga e o tempo, o que indicou um efeito acumulativo. A duração da caminhada por si só e pelo lado da tarte não apresenta efeitos significativos; No entanto, a interação entre os lados e a carga sugeriu diferenças específicas de acordo com a condição.

Discussão: Os hallazgos sugerem que o aumento das exigências mecânicas derivadas de cargas mais pesadas conduzem a mudanças adaptativas nos padrões de carga do antepié. O stress acumulativo refletiu respostas compensatórias ao peso externo sustentado, o que realçou a vulnerabilidade do antepé durante o crescimento e a sua possível ligação com as tensões musculoesqueléticas ao longo do percurso.

Conclusões: O estúdio concluiu que uma gestão adequada do carregamento da mochila e avaliações periódicas da marcha são essenciais para reduzir a pressão excessiva no antepé.
