Resumo: | The aim of the study was to compare maximum oxygen uptake, maximum heart rate, speed corresponding to VO2max, time to exhaustion, and ventilatory thresholds between two maximal test protocols (scaled vs ramp) with equalized metabolic demand in apparently healthy young adults. Twenty-seven subjects of both sexes were analyzed and submitted to two maximum tests: 1) scaled test with 1.2 km∙h-1 every 2 min; 2) ramp test with 0.1 km∙h-1 every 0.18 min; both with 1% slope and maximum total duration of twenty minutes. Respiratory gas exchanges were directly analyzed, and ventilatory thresholds determined through visual inspection. Central tendency and dispersion measures were adopted, as well as paired t-test and effect size. Bland-Altman analysis verified the agreement among variables. Maximum speed showed significance difference (p < 0.01) for the scaled test (14.0 ± 1.9 km∙h-1) and ramp test (14.6 ± 2.3 km∙h-1). Even with small BIAS values, negative trend and high limits of agreement could be observed. Despite the non-difference presented for variables, except for maximum speed, it could be concluded that the scaled test is able to determine the analyzed variables similar to the ramp test, considering the same conditions of the present study. |

Graded and ramp protocols present similar results in apparently healthy subjectsProtocolo escalonado e de rampa apresentam resultados similares em indivíduos aparentemente saudáveisThe aim of the study was to compare maximum oxygen uptake, maximum heart rate, speed corresponding to VO2max, time to exhaustion, and ventilatory thresholds between two maximal test protocols (scaled vs ramp) with equalized metabolic demand in apparently healthy young adults.

Maximum speed showed significance difference (p < 0.01) for the scaled test (14.0 ± 1.9 km∙h-1) and ramp test (14.6 ± 2.3 km∙h-1).

Vinte e sete sujeitos de ambos os sexos foram analisados e submetidos à dois testes máximos: 1) escalonado com 1,2 km·h-1 a cada 2 min; 2) rampa com 0,1 km·h-1 a cada 0,18 min; ambos com 1% de inclinação e duração total máxima prevista de vinte minutos. As trocas respiratórias foram analisadas diretamente, e os limiares ventilatórios determinados por inspeção visual. Medidas de tendência central e dispersão foram adotadas, assim como um teste t pareado e tamanho do efeito. A análise de Bland-Altman verificou a concordância entre as variáveis. A única variável a apresentar diferença estatística (p < 0,01) foi a velocidade máxima (escalonado = 14,0 ± 1,9 km·h-1) e (rampa = 14,6 ± 2,3 km∙h-1). Mesmo com baixos valores de BIAS, é possível verificar uma tendência negativa assim como altos limites de concordância. Apesar da não diferença apresentada para as variáveis, exceto para a velocidade máxima, é possível afirmar que o teste escalonado é capaz de determinar as variáveis analisadas de modo semelhante ao teste rampa considerando as mesmas condições do presente estudo.Universidade Federal de Santa Catarina.
