Weve looked at muscle fibre typology of world-class cyclists in different disciplines, and also how typology may affect recovery from high-intensity workouts. Now lets explore how typology may affect the risk for overreaching after a high increase in training volume.In my last two articles, we discussed a Belgian/Australian collaboration using non-invasive imaging techniques to determine the relative muscle fibre typology of world-class cyclists across disciplines (Lievens et al. 2020a). We saw that BMX and track sprinters were at one end of the spectrum with high proportions of fast-twitch muscles. Road climbers were at the opposite end with high slow-twitch composition.We moved from there to how muscle fibre typology might actually lead to different responses to an acute, high-intensity interval training (HIIT) session (Lievens et al. 2020b). There, we saw that cyclists with higher proportion of fast-twitch muscle fibres had much greater decrements in functional capacity following a hard session of 3 Wingate sprints. This lasted through the entire 5 hours post-training that was studied. In contrast, those with a greater proportion of slow-twitch fibres had minimal decrement in capacity after the same workout despite a similar workload during the intervals.Too much training for your muscle-fibre typologyMuscle Type and Over-ReachingThis second study suggests that not just the training, but the amount of recovery, is highly dependent on individual characteristics and require careful individualization. But what about response to training volume? Might muscle-fibre typology influence the risk for functional over-reaching after a big training block?The above studies were a collaboration between Belgian…
