Abstract
AbstractIntroductionThe submaximal tests are used to measure aerobic capacity and correlate with activities of daily living in chronic patients. The 6‐min handbike cycle test (6mhct) was created for nonambulatory subjects, but there are no reference values to quantify and classify the cardiorespiratory fitness of children in this condition.Objective(s)Generate 6mhct reference values and determine predictive variables in a population of Chilean children between 8 and 13 years old.Materials and MethodsCross‐sectional study. Sampling for convenience, stratified by age. Evaluation of anthropometric variables, handgrip strength, heart rate (HR), effort perception, and blood pressure were performed, then the 6mhct was applied. Descriptive statistics, Student's t test and Mann–Whitney U test, correlation coefficient, and regression equation were used to estimate the total revolutions by age, being significant p < 0.05.ResultsWere evaluated 120 children homogeneously distributed by age. The total revolutions performed by boys and girls were 861.4 ± 102.9 and 771.8 ± 90.2, respectively (p < 0.001). There was a significant correlation between total revolutions and age (r = .52), weight (r = .29), height (r = .46), average UULL (length of the upper limb) length (r = .44), average handgrip strength (r = .53), peak HR (r = .67), recovery HR (r = .44), and HR reserve (r = .72). The regression equation was established.ConclusionsThese results can be used as preliminary reference values for the 6mhct in Chilean children from 8 to 13 years old. Handgrip strength, age, peak HR, and HR reserve influenced the performance of the 6mhct.
