Tendência secular da aptidão física: estudo da população escolar masculina da Ilha de São Miguel dos 10 aos 15 anos de idade
| Resumo: | The thematic related to young people who have a nutritional condition associated with morphologic indicators outside the accepted standards for their age, as well as the issue related to the assessment of the physical fitness levels, have been widely described and discussed in several countries. From this perspective, the objective of this study consisted in assessing the nutritional condition of the decennial variation as well as the decennial effect on the variables of physical fitness in male students from the island of São Miguel and to compare the results with the studies made in 1989 and 1999 on this population. The sample consisted of 214 public school male students between 10 and 15 years of age. Information on the nutritional condition was obtained from an evaluation that was based on the body mass index [BMI = weight (kg) /height (m) 2], using the criteria published by Cole et al. (2000), and adopted by the International Obesity Task Force. Whereas the physical fitness was assessed by the throw of the medicinal 2 kg ball, the pitch of the softball ball, the manual dynamometry, sit-ups, and the push and the horizontal thrust tests. The distribution of the sample according to the anticipated categories for the assessment of the nutritional condition of the decennial variation, was analyzed according to the criteria previously referred, having accordingly, created a chart for this purpose. Charts were made for each age group (10, 11, 12, 13, 14, and 15 years old) with descriptive statistics of the decennial effect on the variables of physical fitness (mean, standard deviation and analysis of variance ANOVA) for a level of significance of 1% and 5%. Version 15.0 of the statistical package SPSS for Windows (Statistical Package for the Social Sciences) was used. According to the cut-off values adopted by the International Obesity Task Force and published by Cole et al. (2000), the results not only indicated a high portion of overweight and obese children (25%), but found as well, that the increasing number of cases has augmented in the last decades (5% from decade to decade). Concerning motor performance, its increase was evident in accordance with the age of the children, with exception to the medicinal ball throw test, where the 10 year old subjects reached values higher than their 11 year old peers. The same occurred in the speed test and for the 11 year old subjects having these recorded a lower average, compared with the 12 year old subjects. In the case of the values achieved by the subjects of different ages (from 10 to 15 years old) and in the various physical tests, there was indication of a decrease in the levels of physical fitness when compared with the results achieved by their peers of the same age in previous editions, confirming in most cases statistically significant differences, except for the manual dynamometry test for the ages between 10 and 14 years old and the sit-ups test, for the ages of 10, 12 and 15 years old, where the trend in these cases pointed to a positive development. |
