Bishop D et al. - The results demonstrate that the decrease in running economy, subsequent to 60 min of cycling, is not affected by the cycling strategy employed. While different glycogen depletion patterns in the type I and II fibres were observed between conditions, total glycogen depletion may be more important to subsequent running economy. The percentage of type I fibers was associated with the glycogen depletion pattern during constant-load, but not variable-intensity exercise.
