- Physical activity, physical fitness and motor competence according weight status: a study in Cape Verdean school childrenPublication . Lopes, Vitor P.; Lopes, Otniel J.P.BOverweight in children and adolescents a serious problem to public health in XXI century. This study aimed to analyse the differences in levels of physical activity (PA), physical fitness (PF) and motor competence (MC) according to the weight status, in schoolchildren from the Island of Santiago, Cape Verde. This cross-sectional study was carried out in 2017, with a sample of 145 boys and 198 girls, with 13.5 ± 0.8 years of age. Height and weight were used to determine the values of body mass index (BMI, kg / m 2), and weight status Weight status was classified according to IOTF cut values for BMI. The pedometer was used to evaluate the PA, four fitnessgram battery tests and the grip strength test were used to evaluate the PF. MC was evaluated with KTK and TGMD- 2. The descriptive statistics were calculated for all variables and the differences according to the weight status were analysed with Kruskal-Wallis test. Although there are children who are overweight, obese and underweight, most of them are normoponderal. PA did not present significant differences between weight status categories. Concerning to PF, there were significant differences in the arms extension, mile run and grip strength tests. Considering MC, there were no significant differences between the categories of weight status for both boys and girls. In conclusion, the sample was mostly normoponderal, with emphasis on the prevalence of low weight in relation to overweight/obesity. With significant differences between weight categories in PF and MC tests.

- Relación entre adiposidad corporal y aptitud aeróbica en adolecentes de la Isla de Santiago (Cabo Verde)Publication . Lopes, Otniel J.P.B; Vidal Espinoza, Rubén; Cossio-Bolaños, Marco; Gómez-Campos, Rossana; Urra-Albornoz, Camilo; Lopes, Vitor P.El exceso de adiposidad corporal, general-mente se considera como un factor negativo en el rendi-miento físico.Objetivo: Comparar los niveles de adiposidad corporal yaptitud aeróbica con estudios referenciales y verificar la re-lación entre adiposidad corporal con la aptitud aeróbica deadolescentes. Material y Métodos: Se efectuó un estudio descriptivocomparativo-correlacional. Fueron estudiados 113 adolescen-tes con un rango de edad entre 12,0 a 16,9 años (89 hom-bres y 113 mujeres). Se evaluó el peso, la estatura, circunfe-rencia de la cintura CC y la aptitud aeróbica (AA) por mediode la prueba de la Milla. Se calculó el Índice de Masa Corporal(IMC) y VO2max (ml/kg/min-1). Resultados: En los hombres, los valores del IMC son infe-riores desde -11.60 a -13.50kg/m2, en la CC desde -9,80 a -15,90cm. En las mujeres, el IMC es inferior desde -3.90 a -5.20kg/m2 y en la CC desde -2,40 a -5,40cm. En la AA, el VO2maxfue superior a la referencia, en hombres los valores oscilan en-tre 4,20 a 9,50 ml/kg/min y en mujeres oscilaron desde 3,90 a5,60ml/kg/min. Las correlaciones entre IMC y CC con VO2maxen hombres fueron negativas (r= -0,62 a -0,58; p<0,001) y enmujeres fue de (r= -0,83 a -0,81; p<0,001). Se verificó que losadolescentes clasificados con exceso de peso presentaron va-lores inferiores de AA en relación a los normopeso y bajo peso.Esto indica que los adolescentes deben reflejar valores de adi-posidad aceptables, no solo para mantener adecuadamente suestado nutricional, sino también para mejorar su capacidadcardiorespiratoria.Conclusión: Los parámetros de adiposidad corporal fue-ron inferiores y los niveles de AE fueron superiores en com-paración con sus respectivas referencias. Además, se observóque la AE se asocia inversamente con los indicadores de adi-posidad corporal en adolescentes de ambos sexos.
- Variation in physical activity, fitness and motor competence according to weight status of 12-15 years youngsters from Cabo VerdePublication . Lopes, Otniel J.P.B; Malina, Robert M.; Lopes, Vitor P.Aim: evaluate physical activity (PA), physical fitness (PF) and motor competence (MC) relative weight status among Cabo Verde youth. Height and weight were measured in 343 boys and girls 12-14 years. PF tests included grip strength, push-ups, curl-ups, sit-and-reach, one-mile-run/walk. KTK tests were the indicator of MC. PA was estimated with pedometers. ANCOVA was used. PA and MC did not vary consistently with weight status. Cardiorespiratory fitness and grip strength per unit mass of thin girls was significantly better than normal weight and overweight/obese girls. Underweight boys performed significantly better in grip strength per unit mass than normal and overweight/obese boys. In conclusions, differences among youth by weight status were not apparent except for the one-mile run in girls and grip strength per unit body mass in both sexes. MC differed by weight status only among girls
