Variáveis fisiológicas obtidas em testes do tipo abertos ou fechados são sugeridas para predizer o desempenho atlético em ciclistas. Contudo, não se sabe quais destas variáveis conseguiriam explicar melhor o desempenho no ciclismo. Este estudo analisou quais variáveis poderiam predizer o desempenho em um simulado de ciclismo (63,5km). Ciclistas (n=15) foram submetidos a diferentes testes para a obtenção das seguintes variáveis: VO2MAX, WPICO, LAn e o TLIM. Em adição, testes fechados de 20 km (TT20km) e 5 km (TT5km), foram realizados. Significantes correlações foram observadas entre o desempenho no simulado de ciclismo e a WPICO (r= -0,83; p= 0,00), o TT20km (r= 0,71; p= 0,00), e a WLAn (r= -0,63; p= 0,01). Modelos regressivos simples e múltiplos Stepwise apresentaram a WPICO e o TT20km como as variáveis a prover as melhores estimativas, com menor erro padrão de estimativa (< 3 minutos). Contudo, a WPICO foi a única variável a entrar no modelo regressivo múltiplo, explicando 68% da variância do tempo. Apesar do apelo teórico apontando maior validade ecológica nos testes fechados, foi uma variável derivada do teste aberto, a WPICO, a melhor explicar o rendimento na competição simulada.
