Recording daily routines with guidance on healthy lifestyle to improve health parameters in children and their families

This study investigated the efficacy of using a diary to record daily routines, combined with guidance on healthy lifestyle (GHL) by a physical educator, on promoting changes in health parameters in children. Sixty-three children (10 ± 0.8 years) were allocated to one of the three following groups: a control group (CON, n = 18); a group that did not use the diary, but received GHL (G, n = 23); or a group that both used the diary and received GHL (DG, n = 22). Blood pressure, body composition, physical fitness tests (PF), physical activity levels (PAL), and dietary intake profiles were assessed in children and their parents before and after 2 months of intervention. The DG group improved their performance in PF, increased PAL, and reduced body fat (p < 0.05). Additionally, 56% of families from both DG and G reduced their consumption of unhealthy foods and 70,6% increased their consumption of healthy foods. Overall, it was concluded that 2 months of using a diary to record daily routines combined with GHL by a physical educator improved PAL, PF, body composition, and dietary intake profiles of children and their families

Parâmetros cardiovasculares, antropométricos, VO2máx e atividade física de escolares da cidade de Teresina-PI / Cardiovascular, anthropometric, VO2max and physical activity parameters of school from Teresina-PI

O nível de atividade, aptidão física e medidas antropométricas na infância vêm sendo relacionadas com o desenvolvimento de doenças cardiovasculares na vida adulta. Esses parâmetros são pouco estudados na região nordeste, e mais especificamente no Piauí. Sendo assim, o objetivo do presente estudo foi traçar o perfil dos níveis de atividade física e fatores de risco cardiovasculares em escolares com idade entre 8 a 10 anos na cidade de Teresina-PI. Participaram do estudo 307 escolares de ambos os sexos, com idade entre 08 e 10 anos, devidamente matriculados na rede escolar municipal de Teresina-PI. Os voluntários responderam a um questionário para identificar o nível de atividade física (NAF) dos escolares e foram submetidos à avaliação da massa corporal, estatura, índice de massa corporal e aptidão física e pressão arterial. Meninos e meninas de oito, nove e 10 anos de idade da cidade de Teresina-PI não diferem entre si em relação a parâmetros antropométricos, cardiovasculares e NAF. Porém as comparações intra grupos das medidas antropométricas, apresentam que a idade de oito anos difere das idades de nove e 10 anos. Adicionalmente, o VO2máx declina a partir de oito anos em ambos os sexos. A partir de oito anos, as crianças de Teresina-PI, apresentam diminuição da aptidão física e mudanças de parâmetros antropométricos. Essas informações são importantes para a Educação Física regional para atitudes de prevenção de doenças cardiovasculares, uma vez que esses parâmetros estão relacionados diretamente com doenças da vida adulta.

Activity, physical fitness and anthropometric level in childhood has been linked with cardiovascular diseases in adulthood. These parameters are little studied in the northeast, and more specifically in Piauí. Therefore, the aim of study was measurement the physical activity and cardiovascular risk levels in schoolchildren with the ages ranging from 8 to 10 years old in the city of Teresina-PI. The study included 307 schoolchildren of both sexes, aged between 08 and 10 years, unrolled in the municipal school of Teresina-PI. The subjects answered a questionnaire in order to identify the physical activity level (NAF) of the students and were submitted to an assessment of body mass, height, body mass index and physical fitness and blood pressure. Boys and girls from eight to 10 years old the city of Teresina-PI did not differ in relation to anthropometric, cardiovascular and NAF parameters. But the intra-group comparisons of anthropometric measurements, point out that the age of eight differs from nine and 10 years old. Furthermore, the VO2máx declines from the age of eight in both gender. From eight years old onwards, children from Teresina-PI, have reduced physical fitness and changes in anthropometric parameters. This information is important for the Physical Education Regional to take measures for preventing cardiovascular diseases, once these parameters are directly related with adulthood diseases.

Estilo de vida e níveis de aptidão física relacionada à saúde em adolescentes de Demerval Lobão/PI / Health related lifestyle and physical fitness levels in adolescents

O objetivo deste estudo foi investigar o estilo de vida e níveis de aptidão física relacionada à saúde em alunos de 14 a 19 anos do ensino médio de uma escola pública na cidade de Demerval Lobão - PI. A amostra foi de 74 (48 meninos e 26 meninas) adolescentes com idade 16,72±1,28 anos. Realizaram-se os testes de sentar e alcançar para avaliar a flexibilidade, força/resistência abdominal e flexão de braços até a exaustão. Determinou-se o percentual de gordura (%MG) pelo protocolo de Lohman. Já o estilo de vida relacionado à saúde, pelo questionário Perfil do Estilo de Vida – PEVI. Dos adolescentes pesquisados, 71,62% têm um estilo de vida relacionado à saúde regular. Quanto ao índice de massa corporal e %MG, respectivamente, 10,8% e 16,2% estavam sobrepesados. As meninas foram inferiores aos meninos na resistência abdominal e flexão de braços, mas superiores a eles na flexibilidade. Concluise que os adolescentes têm um estilo de vida regular, e grande parte dos escolares está dentro da zona saudável. Com exceção da flexibilidade nos meninos, todos os componentes reduziram conforme a adiposidade ascendia.

The aim of this study was to investigate lifestyle and health related physical fitness levels in high school students between 14 to 19 years of a public school in the city if Demerval Lobão - PI. The sample was 74 adolescents (48 boys and 26 girls) aged 16.72±1.28 years. Tests of seat and reach to evaluate the flexibility, abdominal strength/endurance and ground arm flexion to exhaustion were performed. Body fat percentage (%BF) was determined by the protocol of Lohman . Health related lifestyle was determined by the questionnaire Profile of Lifestyle – PEVI. From the evaluated adolescents, 71.62% presented a regular health related lifestyle. Regarding the body mass index and %BF, 10.8% and 16.2% were overweight, respectively. The girls presented inferior results for the abdominal endurance and ground arm flexion as compared with the boys, while boys were inferior to girls for flexibility. It was concluded that adolescents present a regular lifestyle and the most part of the scholars is in the healthy zone. With exception to flexibility in boys, all evaluated components reduced as adiposity increased.

Intraocular pressure variation during weight lifting.

OBJECTIVE: To evaluate the effect of weight lifting on intraocular pressure (IOP). METHODS: Subjects performed 4 repetitions of a bench press exercise in 2 ways: in mode I (right eyes), the breath was held during the last repetition; in mode II (left eyes), subjects exhaled normally during the last repetition. The IOP was measured with an electronic tonometer during the fourth repetition in both modes while the subject sustained the exercise. RESULTS: Mean IOP during exercise in mode I increased by 4.3 +/- 4.2 mm Hg (P<.001, paired t test; range, -3.6 to 17.7 mm Hg). In mode II, mean IOP increased by 2.2 +/- 3.0 mm Hg (P<.001, paired t test; range, -6.0 to 8.7 mm Hg). The IOP increased in 90% of subjects in mode I and in 62% in mode II. An increase in IOP greater than 5.0 mm Hg was observed in 9 subjects (30%) in mode I and in 6 (21%) in mode II. In 2 subjects, IOP during exercise mode I was markedly increased (>10.0 mm Hg). CONCLUSIONS: The IOP increases significantly during a bench press exercise. Breath holding during the exercise leads to a greater IOP increase.
