“…The T9 is also one of the methods indicated for the evaluation of cardiorespiratory fitness in schoolchildren by the Brazilian Sports Project (Projeto Esporte Brasil) 8 . An association of unsatisfactory performance in this test with obesity and comorbidities has been observed in adolescents 10,13,14 . In view of the possibility that a cardiorespiratory fitness test such as the T9 could have broad applicability for health risk assessment in the school environment and since it is less prone to the limitations inherent to questionnaires in general 15 , the question is whether the results obtained with this test are correlated with the physical activity levels obtained by the IPAQ.…”

“…In this respect, additional validation studies using a gold standard and representative samples of the population of Brazilian adolescents should be conducted to better understand the relationship between these two constructs and to guide exercise prescription as a tool for health promotion 30 . The criteria used to determine the cut-off values that classify test performance should be reviewed and discussed as done in the studies of Bergmann et al 10 and Paludo et al 12 .…”

“…Cardiorespiratory fitness can be estimated by practical field tests that permit to evaluate a large number of subjects over a short period of time 8,9 . The 9-minute run/walk test (T9) has been applied in epidemiological studies conducted in Brazil [10][11][12] and in other countries [12][13][14] , since it is a valid, reproducible, objective and low-cost test. The T9 is also one of the methods indicated for the evaluation of cardiorespiratory fitness in schoolchildren by the Brazilian Sports Project (Projeto Esporte Brasil) 8 .…”

-More objective methods to detect inactive adolescents may help identify young people that are vulnerable to obesity and other chronic diseases. The objective of this study was to examine the association between classifications obtained with the cardiorespiratory fitness test and physical activity level in adolescents, as well as the agreement between tertiles and z-score distribution of the variables generated with these methods (distance covered and total physical activity score). A cross-sectional study was conducted using a random sample of 639 adolescents (61% girls) aged 12 to 19 years (mean age of 16 ± 1.8 and categorized into two age groups: 12-13 and 14-19 years), from public schools in Niterói, Rio de Janeiro, Brazil. Cardiorespiratory fitness was assessed by a 9-min run/walk test (T9) and physical activity level by the International Physical Activity Questionnaire (IPAQ). The chi-square test (or Fisher's exact test) and Kruskal-Wallis test were applied for the evaluation of associations, and the weighted kappa coefficient and intraclass correlation coefficient were used to investigate agreement between variables. A level of significance of p<0.05 was adopted. A significant association between the classifications obtained with the two methods was only observed for adolescents aged ≥ 14 years. However, there was agreement between the variables generated with the two methods in both age groups. The median distance covered in the T9 increased according to tertiles of total physical activity score. An association between the classifications obtained with the IPAQ and T9 was only found for older adolescents. However, the continuous variables and variables categorized into tertiles generated with the methods were associated and showed agreement in both age groups.

“…In addition, regular practice of physical activity in this age group results in increased chance of maintaining these habits into adulthood, contributing to maintaining adequate HRPF levels 9 . The appearance of various risk factors for cardiovascular diseases is among the main health problems associated with low HRPF in children and adolescents 3,10,11 , strongly related to ApC and body composition, complaints of back pain and identification of postural deviations 12 related to Flex and F/R. The presence of low back pain appears to influence the population's quality of life and may even limit the performance of common tasks of the daily living 13 .…”

-Low back pain is increasing considerably among adolescents, reaching proportions similar to the adult population. Flexibility (Flex) and muscle strength/resistance, components of Health-Related Physical Fitness (HRPF), seem to be associated with presence of low back pain. The aim of this study was to assess the ability of Flex and muscle strength/resistance in the screening of adolescents with low back pain and to propose cutoff points for these HRPF components. The study was conducted with 1.455 students aged 10-17 years randomly selected. Low back pain was estimated using a questionnaire. Flex was measured by the sit and reach test and muscle strength/resistance by the one minute sit up test. The analysis of the receiver operating characteristic (ROC) curve was used to identify the capacity of Flex and muscle strength/resistance for screening low back pain. To propose cutoffs points, the best balance between sensitivity and specificity was analyzed. The frequency of low back pain was 16.1 %, higher (p<0.05) among females (21.6%) than in males (10.5%). The ROC curve analysis indicated that Flex is able to identify girls more likely of having low back pain (p<0.05). Sit and reach test and the proposed cutoff points can be used as screening tool of female adolescents more likely of having low back pain.Key words: Adolescents; Health; Low back pain; Roc curve.

RESUMOObjetivo: Desenvolver e validar modelos matemáticos para predição do VO 2pico em crianças e adolescentes, por meio da utilização do teste de campo de corrida/caminhada de 9 minutos. Métodos: Foram avaliados 211 escolares, de sete a 12 anos de idade, de ambos os sexos, regularmente matriculados em duas escolas do Município de Londrina -PR, sendo 141 escolares separados para amostra de desenvolvimento e 70 para validação das equações desenvolvidas. As medidas avaliadas foram: massa corporal, estatura, espessuras de dobras cutâneas (tricipital e subescapular), além da maturação biológica. Os testes de corrida/caminha de 9 minutos foram realizados em pista de atletismo e a análise direta do VO 2pico (mL/kg/min ) realizada em laboratório, com analisador de gás portátil, através um teste incremental em esteira rolante. O desenvolvimento das equações foi realizado através da análise de regressão linear pelo método stepwise e a validação foi realizada pelos testes matemáticos específicos levando em consideração uma significância de 5% para todas as análises. Resultados: A equação geral para a amostra total foi VO 2pico = 24,506+16,672 (maturação, 0=pré e 1=púbere e pós) -0,346 (Σ DC) + 5,187 (sexo, 0=F e 1=M) + 0,009 (distância) com um r=0,742 e EPE=9,149 mL/kg/min e sua validação apresentou r=0,570, CCI= 0,68, limites de concordância de -1,4 mL/kg/min, EPE=8,39 mL/kg/min e CV= 21,94%. Conclusão: Conclui-se que a equação generalizada desenvolvida fornece uma estimativa válida do VO 2pico em crianças e adolescentes de sete a 12 anos de idade. Palavras
