Dr Glenn McConell chats with Professor Lars Nybo from the University of Copenhagen. He is an expert on the effects of environmental conditions on exercise. Here he discussed factors effecting cycling performance and then focused on circumstances where one needs to be careful applying findings from the lab to the real world. A very interesting chat.
