Resumo

Introdução: A utilização de bicicletas elétricas de montanha aumentou o interesse pela sua contribuição para a atividade física e para a saúde, mas as evidências em situações reais são ainda limitadas.   Objectivo: Este estudo explorou se a transição de uma bicicleta de montanha convencional para uma bicicleta de montanha elétrica permitiu a um ciclista recreativo manter intensidades saudáveis ​​em diferentes níveis de assistência.   Metodologia: Um estudo longitudinal de caso único foi conduzido ao longo de dezasseis semanas. Foram comparadas quatro condições: uma bicicleta convencional e uma bicicleta elétrica com três configurações de assistência. A frequência cardíaca, a velocidade, a potência, a cadência, a inclinação, a perceção de esforço e os índices de carga foram registados durante vinte e oito percursos em situações reais (778 quilómetros).   Resultados: Foram observadas diferenças fisiológicas entre as condições. Neste participante, os modos de assistência mais baixos e o modo restrito estiveram associados a intensidades moderadas a vigorosas e a uma menor carga fisiológica momentânea do que a bicicleta convencional. Em subidas íngremes, alguns modos de assistência atingiram intensidades relativas próximas do limiar funcional de potência.   Discussão: Os padrões foram consistentes com estudos anteriores que descreveram respostas relevantes quando a assistência foi regulada e mostraram a influência do terreno e do modo de condução.   Conclusões: Este estudo exploratório sugere que alguns utilizadores conseguem manter intensidades saudáveis ​​nas bicicletas elétricas sob condições específicas.
