Physical fitness in children in Cabo Verde: differences between gender, eutrophic vs. overweight subjects, and practitioners vs. non-practitioners of sports.

Abstract

There are few or even rare studies conducted in Cabo Verde (Republic of Cabo Verde) that address the issue of physical fitness and body composition in the juvenile population. This investigation aims to study the physical fitness in children in Cabo Verde: differences between gender, eutrophic, and overweight subjects, between practitioners and non-practitioners of sports. The sample consisted of 93 individuals aged between 10 and 15 years, from the 2nd and 3rd cycles and secondary school of the Portuguese College based in Cabo Verde. The instruments used for data collection were the FITescola® test battery (Lisboa, Portugal), and the questionnaire Quantification de l'activite physique en altitude chez les enfants (QAPACE) for assessment of physical activity level. Regarding the statistical analysis using the SPSS 23.0 software (SPSS Inc., Chicago, IL, USA), the first analysis was performed to verify the distribution of the sample (Kolmogorov-Smirnov Test and Shapiro-Wilk Test). Then, for variables with normal distribution we used the t-test and for the remaining variables with non-normal distribution we used the Mann-Whitney Test, with a significance level of 5%. Gender differences were found, in which the male gender obtained more favorable mean values in the "sit-ups," "push-ups," "horizontal impulsion," "shuttle" and "agility" variables, while the females showed superiority in the variables "sit and reach;" differences between the eutrophic and overweight group where, as expected, more favorable mean values for eutrophics than the overweight group in all PF tests. Finally, differences between practitioners and non-practitioners of sports, with the best results being attributed to practitioners of sports. We concluded that male subjects have greater proficiency in strength and aerobic fitness tests while female subjects have greater flexibility. High BMI values in overweight children have been found to be associated with increased abdominal fat as well as a reduction in overall PF. As expected, sports practitioners show better results in motor performance on PF tests.
