Abstract(s)
Mesmo sabendo que um estilo de vida saudável pode trazer muitos benefícios para a
saúde, vários são os estudos epidemiológicos que identificam um aumento da
prevalência da inatividade física nas crianças e adolescentes. Neste contexto, o papel do
exercício físico realizado em contexto escolar torna-se fundamental para o estímulo de
comportamentos benéficos para a saúde e bem-estar individual. Na escola, os alunos
estão sujeitos a vários currículos, com diferentes cargas letivas e conteúdos. Assim, o
objetivo do presente estudo foi verificar o efeito de diferentes quantidades de prática
semanal de exercício físico, durante 11 semanas, nos níveis de aptidão física de alunos
da Escola Profissional da Nazaré. A amostra foi constituída por 42 alunos de ambos os
sexos, com idades compreendidas entre os 17 e os 19 anos. Destes 42 alunos, 23
pertenciam ao curso Técnico de Desporto (17 masculinos e 6 femininos) e 19
pertenciam ao curso Técnico de Cozinha (11 masculinos e 8 femininos). Para avaliar a
aptidão física, os alunos realizaram a avaliação da força superior, força média, força
inferior e aptidão cardiorrespiratória no início do 1º período do ano letivo 2020/2021, e
no final do 1º período. Durante este período o curso Técnico de Desporto apresentou
uma componente prática semanal de 13 horas, correspondentes às disciplinas de
modalidades desportivas coletivas, modalidades desportivas individuais, fitness e
musculação e Educação Física. O curso Técnico de Cozinha apresentou uma
componente prática semanal de 2 horas, correspondentes à disciplina de Educação
Física. Foram verificadas melhorias significativas nos valores de força superior, média,
inferior e na aptidão cardiorrespiratória nos alunos do curso Técnico de Desporto (p =
0.01) e no curso Técnico de Cozinha (p = 0.02). Comparando as turmas, não foram
observadas diferenças nas flexões de braços (F = 2.50, p = 0.12), abdominais (F = 0.29,
p = 0.59) e no salto horizontal (F = 0.12, p = 0.73), somente no teste de vaivém (F =
8.90, p < 0.01) com ganhos superiores para os alunos do curso profissional de Técnico
do Desporto. Os resultados sugerem que, apesar das melhorias da força e aptidão
cardiorrespiratória serem evidentes em qualquer turma do ensino secundário
profissional, a turma com maior prática semanal de exercício físico tem ganhos
superiores de aptidão cardiorrespiratória.
Even though a healthy lifestyle can bring many benefits to health, several epidemiological studies identify an increase in the prevalence of physical inactivity in children and teenagers. In this context, the role of physical exercise performed in the school context becomes fundamental for the encouragement of beneficial behaviours towards individual health and well-being. At school, students have several subjects, with different schedules and contents. Thus, the present study aimed to verify the effect of different weekly hours of a physical activity practice, for 11 weeks, on the levels of physical aptitude of the Nazaré’s Vocational School students. The sample consisted of 42 students of both sexes, aged between 17 and 19 years. Of these 42 students, 23 belonged to the Sports vocational course (17 male and 6 female) and 19 from the Cook and Pastry vocational course (11 male and 8 female). To assess physical aptitude, students were assessed for upper strength, abdominal strength, lower-limbs strength and cardiorespiratory fitness at the beginning and the end of the 1st period of the 2020/2021 school year. During this period, the Sports vocational course had a weekly practical component of 13 hours, corresponding to the subjects of collective sports, individual sports, fitness and bodybuilding and physical education. The Cook and Pastry vocational course had a weekly practical component of 2 hours, corresponding to the subject of physical education. There were significant improvements in the values of upper-strength, abdominal, lower-strength and cardiorespiratory fitness in the students of the Sports vocational course (p = 0.01) and the Cook and Pastry vocational course (p = 0.02). Comparing both courses, no differences were observed in the pushups (F = 2.50, p = 0.12), sit-ups (F = 0.29, p = 0.59) and in the horizontal jump (F = 0.12, p = 0.73). Only in the shuttle test (F = 8.90, p < 0.01) there were higher gains in the Sports vocational course students. The results suggest that, despite the improvements in strength and cardiorespiratory fitness being evident in every class of the secondary vocational courses, the group with the highest weekly physical exercise practice has greater gains in cardiorespiratory fitness.
