Resumo: | ABSTRACT The objective of the present study was to investigate the infl uence of two linear models on the determination of critical potential (CP) and anaerobic work capacity (AnWC) of canoeists evaluated on an arm ergometer. Eight male canoeists (17.1 ± 1.1 years; 63.3 ± 6.5 kg; 173.4 ± 4.3 cm) volunteered to take part in the study. Two different linear equations were employed to calculate CP and AnWC: power-1/time and work-time, using three different power levels (Wlim) and their respective times to exhaustion (tlim). The athletes underwent six test sessions on an arm ergometer at 70 rpm until voluntary exhaustion, with and interval of 24 hours between sessions, at two different intensities each day, with a minimum interval of 90 minutes. The statistical analysis employed descriptive statistics, Student’s t test and Pearson’s linear correlation (P < 0.05). The power-1/time equation produced a signifi cantly higher CP than the work-time equation (144.6 ± 17.3 W vs. 141.9 ± 16.5 W, respectively; P < 0.05), whereas AnWC was significantly greater when calculated by work-time than when calculated by power-1/time (12.8 ± 2.9 kJ vs. 13.9 ± 3.2 kJ; respectively, P < 0.05). The coefficient of correlation between power-1/time and work-time for CP and AnWC was r=0.98 and r=0.92, respectively (P < 0.05). Despite this high level of correlation between the models in terms of CP and AnWC, the results suggest that adopting different models appears to interfere in the calculation of CP and AnWC of exercise on an arm ergometer. |

Para tanto, oito canoístas do sexo masculino (17,1 ± 1,1 anos; 63,3 ± 6,5 kg; 173,4 ± 4,3 cm), participaram voluntariamente desta investigação. A PC e a CTAn foram obtidas por meio de duas equações lineares: potência-1/tempo e trabalho-tempo, utilizando três potências (Wlim) e seus respectivos tempos até a exaustão (tlim). Os atletas foram submetidos a seis sessões de testes em ergômetro de braço a 70 rpm até a exaustão voluntária, com intervalo de 24 horas entre cada sessão, a duas intensidades diferentes a cada dia, com intervalo mínimo de 90 minutos. Para o tratamento estatístico utilizou-se a estatística descritiva, teste t de Student e correlação linear de Pearson (P < 0,05). A PC da equação potência-1/tempo foi significativamente maior que da equação trabalho-tempo (144,6 ± 17,3 W vs 141,9 ± 16,5 W, respectivamente; P < 0,05), enquanto que a CTAn foi signifi cativamente maior no modelo trabalho-tempo em relação ao modelo potência-1/tempo (12,8 ± 2,9 kJ vs 13,9 ± 3,2 kJ; respectivamente, P < 0,05). A correlação obtida para PC e CTAn entre os modelos potência- 1/tempo e trabalho-tempo foram r=0,98 e r=0,92, respectivamente (P < 0,05). Apesar da alta correlação encontrada entre os modelos para os valores de PC e CTAn os resultados sugerem que a adoção de diferentes modelos parece interferir no cálculo da PC e CTAn em exercício realizado no ergômetro de braço.Universidade Federal de Santa Catarina.
