RESUMO

Níveis de treinamento distintos, associados à experiência em realizar esforços exaustivos podem produzir diferentes sensações frente à fadiga. O objetivo deste estudo foi comparar a percepção subjetiva de esforço (PSE) entre ciclistas e não-ciclistas durante teste incremental máximo (TIMAX). Participaram do estudo 23 indivíduos que  foram divididos em grupo ciclistas (GC) (n = 12; idade 26,5 ± 4,7 anos; massa corporal 68,2 ± 11kg; estatura 176 ± 8,6cm) e grupo não-ciclistas (GNC) (n=11; idade 25,2 ± 4,0 anos; massa corporal 72,9 ± 9kg; estatura 175,1 ± 6,3cm). Todos realizaram um TIMAX,  até a exaustão, do tipo rampa em ciclossimulador, com início a 0 W e incrementos de 20 W.min-1.  Durante TIMAX a PSE foi aferida e anotada a cada 30 segundos de teste e, ao final, a potência máxima (PMAX) atingida pelos indivíduos. O tempo total de cada teste foi normalizado em porcentagens (de 10% a 100%, intervalos de 10%), e foi anotada a respectiva PSE para cada intervalo. Os valores de PMAX para GC e GNC foram 368  ± 12,7W e 256 ± 11,2W, respectivamente  (P < 0,01). Os valores das medianas das PSE para GC e GNC não apresentaram diferença significativa para nenhuma porcentagem de tempo. Conclui-se que as respostas de PSE não sofreram alterações entre GC e GNC durante TIMAX, sugerindo que o nível de treinamento não influencia a PSE.

ABSTRACT

Different training levels, combined with experience in performing exhaustive exercise, may produce different sensations of fatigue. The objective of this study was to compare the rating of perceived exertion (RPE) between cyclists and non-cyclists during a maximal incremental test (ITMAX). Twenty-three subjects were recruited and divided into a cyclist group (CG) (n = 12; age: 26.5 ± 4.7 years, body weight: 68.2 ± 11kg, height: 176 ± 8.6 cm) and a non-cyclist group (NCG) (n = 11; 25.2 ± 4.0 years, body weight: 72.9 ± 9 kg, height: 175.1 ± 6.3 cm). All subjects performed an ITMAX until exhaustion on a cycling simulator, starting at 0 W and with increments of 20 W.min-1. RPE was measured at 30-second intervals during ITMAX and the maximal power output (PMAX) of each subject was also recorded. The total time of each test was normalized to the percentage of completed trial (10% to 100%, intervals of 10%), and the corresponding RPE was recorded. PMAX was 368 ± 12.7 W and 256 ± 11.2 W for CG and NCG, respectively (P < 0.01). No significant difference in median RPE was observed between groups at any time point. In conclusion, RPE responses did not differ between CG and NCG during ITMAX, suggesting that training level does not influence RPE.
