Resumo
A relação entre aptidão cardiorrespiratória e um menor perfil de risco cardiovascular tem sido demonstrado em crianças e adolescentes (Janssen & Leblanc, 2010; 2006; Kriemler et al., 2008). Objetivo: verificar a associação entre o consumo máximo de oxigénio ( 2max) e a circunferência da cintura (CC), pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e glicemia em adolescentes utilizando a base de dados do projeto Rastresaúde. Método: este ro eto tin a co o ob etivo ava iar os rinci ais indicadores de sa de cardiovascu ar e inc u a as vari veis 2max A A e ice ia. ontudo nesse ro eto o 2max tinha sido obtido através do chester step test (CST) ue não estava va idado ara ado escentes. este sentido oi rea i ado u estudo re i inar co o ob etivo de estudar a associação entre va ores do 2max estimados utilizando o CST e o teste do Vaivém que está validado para adolescentes (Leger, Mercier, Gadoury, & Lambert, 1988). Pretendíamos com este objetivo poder eventualmente utilizar, os va ores do 2max da referida base de dados. endo-se veri icado u a associação estatistica ente si ni icativa orte e ositiva entre os va ores de 2max obtidos utilizando o CST e o teste Vaivém para o sexo masculino, r=0,92, p<0,05 e para o sexo feminino, r=0,78, p<0,05 decidimo-nos e a uti i ação da base de dados do astresa de. este sentido a re erida base de dados oi uti i ada ara investi ar a associação do 2max com a CC, PAS, PAD e glicemia em adolescentes. Resultados: verificou-se nos indivíduos do sexo feminino uma associação inversa e estatistica ente si ni icativa entre o 2max e a A r - 1 5 entre o 2max e a A r - 1 5 e entre o 2max e a CC, r=-0,182, p< 5. ara os indiv duos do se o ascu ino veri icou-se u a associação inversa e estatistica ente si ni icativa a enas entre o 2max e a CC, r=-0,229, p<0,05 sendo que todas as associações encontradas foram consideradas fracas, r<0,3 (Field, 2005).
Conclusão: os resultados do estudo sugerem uma associação inversa entre o 2max e a PAS, PAD e CC em adolescentes do sexo feminino e entre 2max e a CC em adolescentes do sexo masculino. Dada a escassez de estudos e derivado ao aumento da prevalência dos fatores de risco associados às doenças cardiovasculares na infância e adolescência é relevante realizar mais estudos na população jovem.
The relationship between cardiorespiratory fitness and a lower cardiovascular risk profile has been demonstrated in children and adolescents (Janssen & Leblanc, 2010, 2006; Kriemler et al., 2008). Objective: to investigate the association between maximal oxygen uptake ( 2max) and waist circumference (WC), systolic blood pressure (SBP), diastolic blood pressure (DBP) and glucose in adolescents using the database of Rastresaúde project. Method: this project was aimed to evaluate the main indicators of cardiovascular health, and included the variables 2max, CC, SBP, DBP, and glucose. However, in this project 2max was obtained by Chester Step Test (CST) that was not validated for adolescents. In this sense we performed a preliminary study with the objective of investigate the association between 2max values estimated using the CST and the 20m shuttle run test which is validated for adolescents (Leger, Mercier, Gadoury, & Lambert, 1988). Our goal was to use the values 2max from the Rastresaúde project database. We verified a strong and positive correlation between 2max values obtained using the CST and 20m shuttle run test for males, r= 0.92, p <0.05 and for females, r= 0.78, p <0.05. Then we decided to use the Rastresaúde database. Therefore, this database was used to investigate the association of 2max with WC, SBP, DBP, and glucose in adolescents. Results: it was verified in females a statistically significant inverse association between 2max and SBP, r = -0.138, p <0.05; between 2max and DBP, r = -0.163, p <0.05 and between 2max and CC, r = -0.182, p <0.05. For males it was verified an inverse and statistically significant only between 2max and CC, r = -0.229, p <0.05. All associations found were considered weak, r <0.3 (Field, 2005 .). Conclusion: the results suggest a significant inverse association between 2max and SBP, DBP and WC in female adolescents and between 2max and CC in male adolescents. Given the fewer number of studies and with the increasing prevalence of risk factors associated with cardiovascular disease in childhood and adolescence it is important further studies in young people.
