Cardiorespiratory fitness (CRF) provides oxygen to the exercising muscles and is related to body adiposity, with cardiometabolic variables. The aim was to develop reference values and a predictive model of CRF in Chilean adolescents. A total of 741 adolescents of both genders (15.7 years old) participated in a basic anthropometry, performance in the six-minute walk test (SMWT), and in Course Navette was measured. Percentiles were determined for the SMWT, for the V̇O2max, and an equation was developed to estimate it. The validity of the equation was checked using distribution assumptions and the Bland–Altman diagram. The STATA v.14 program was used (p < 0.05). The 50th percentile values for males and females in the SMWT and in the V̇O2max of Course Navette were, respectively, from 607 to 690 and from 630 to 641 m, and from 43.9 to 45 and from 37.5 to 31.5 mlO2·kg·min−1, for the range of 13 to 17 years. For its part, the model to predict V̇O2max incorporated gender, heart rate, height, waist-to-height ratio (WHR), and distance in the SMWT (R2 = 0.62; estimation error = 0.38 LO2·min−1; p <0.001). Reference values can guide physical fitness in Chilean adolescents, and V̇O2max was possible to predict from morphofunctional variables.

Introdução: O teste de caminhada de seis minutos (TC 6 ) é comumente utilizado na faixa etária pediátrica, e variáveis preditivas e valores de referência têm sido estudados para o teste.Objetivo: Apresentar os achados na literatura sobre a determinação de variáveis preditivas e valores de referência para o TC 6 na população pediátrica.Materiais e Métodos: Revisão de literatura através de pesquisa nas bases de dados eletrônicas PubMed e EBSCO utilizando as palavras-chave: “child”, “six minute walk test”, “reference values” e “6-minute walk test”, buscando estudos que apresentassem valores e/ou equações de referência e apresentação de variáveis preditivas. Não foi utilizada restrição temporal e de idioma nas publicações.Resultados: De um total de 20 estudos, foram selecionados 11, os quais incluíram indivíduos entre 4 e 18 anos. A idade foi a variável de mais frequente relação com o desempenho no teste, seguida de massa corporal, estatura, sexo, variação da frequência cardíaca, índice de massa corporal e nível de atividade física . A altura foi a única variável preditiva comum em todos os estudos. Nota-se que diferentes metodologias e modificações são empregadas na realização do TC 6 .Conclusão: Diferentes equações de referência, bem como variáveis preditivas, são identificadas, sendo apenas a estatura comum nas diferentes publicações analisadas. Mesmo o TC 6 sendo um teste comumente utilizado, não há metodologia de aplicação e padronização em pediatria.

Background The self-paced six minute walk test is a simple assessment for sub-maximal functional capacity. It correlates well with sophisticated tests and gives good prediction for morbidity, mortality, quality of life and pulmonary functions.Objective To evaluate six minute walk distance in healthy adults to identify reference values and formulate reference equations.Method We conducted six minute walk test on 250 random volunteers at and above 18 years of age as per standard protocol. Age, gender, height and weight were measured. Pre-test and post-test vital parameters were recorded including pulse oximetry. The six minute walking distance was identified in all subjects. Multiple regression analysis was done to formulate regression equations to predict six minute walking distance. This also correlated age, gender, height, weight, body mass index with six minute walking distance.Result The mean six minute walking distance was 489±86 meters with males walking 509±82 meters and females 445±78 meters. Age, gender, weight and body mass index had significant contribution for prediction of six minute walking distance. Gender was the single most important predictor. Height had the least significance. Depending on coefficients of these variables we formulated three regression equations and tested them for accurate prediction. The two best equations were identified as: Predicted SMWD = 395–1.5xAge+2.47xWT–35.89xGender and Predicted SMWD = 440–1.82xAge–53.07xGender+5.12xBMI.Conclusion Gender, age and height are the most important predictors of six minute walking distance. Reference values and equations for both genders, different age groups with varying weights were derived for local population.

Background: The use of fitness testing for the identification of women at high-risk of metabolic syndrome (MS), and therefore of cardiovascular disease, is clinically relevant. Objective: The purpose of this study was to determine the ability of a set of physical fitness tests to establish the risk of MS in perimenopausal Moroccan women. Methods: The study comprised 151 women (45–65 years) from the North of Morocco. We used standardized field-based fitness tests to assess cardiorespiratory fitness, muscular strength, flexibility and balance. Fatness was assessed by impedanciometry and anthropometry. We also measured resting heart rate, blood pressure and plasma fasting glucose, total cholesterol, low density lipoprotein (LDL)-cholesterol, high density lipoprotein (HDL)-cholesterol and triglycerides. Results: Women with MS performed worse in most of the fitness tests studied. Among the fitness test studied, the six-minute walk test was the most associated to MS. Receiver operating characteristics curve analyses revealed that the six-minute walk test threshold that best discriminated between the presence and absence of MS was 480.5 m (area under curve (AUC): 0.719, 95% confidence interval (CI): 0.62–0.82; p<0.001). Logistic regression after adjustment for age and weight showed that a distance ≤480 m is associated with 2.9 times higher risk (95% CI: 1.56–7.65; p<0.05) for having MS. Conclusions: Including cardiorespiratory fitness as a MS risk factor may improve early identification of at-risk Moroccan women. Fitness testing provides useful information and is cheap, easy to perform, and not time-consuming, which makes its use in this specific clinical settings feasible.

Purpose: This study attempted to establish reference values of the six-minute walk test (6MWT) for children (38 males; 38 females; age 90-108 months) and to determine the relationship between BMI and walking distance. Method: Subjects walked at a normal, self-selected, walking speed on a grassy field for six minutes, after which distance was measured. Results: Mean BMI was 15.50 (sd=2.00) for males and 16.30 (sd=2.90) for females. Mean walking distance was 581.70 m (sd=58.10) for males and 532.20 m (sd=52.60) for females. The partial correlation between BMI and distanced walked with the influence of gender removed was .10 (p > .05). The partial correlation between BMI and distanced walked with the influence of age removed was .02 (p > .05). There was no relationship between distance walked and BMI. Conclusions: Reference values of the six-minute walk test for healthy, third-grade school children were calculated and reported.walk test, pediatric BMI, body mass index, six minute walk test
