It is not new information that individuals with a higher distribution of type 2 (fast-twitch) muscle fiber fatigue faster. This is likely due to a number of reasons, but this study adds to the body of literature which suggests that fiber distribution is another reason why fatigue tolerance is highly individual. It seems that the ability to be stronger, faster, and more powerful comes at a cost.
This study was the first of it’s kind in that it measured the time course to recovery up to 5 hours post-training, while previous literature measured variations in recovery only minutes after the intervention.
While this study doesn’t really change how I would do anything it does give me more pause to consider how individualized fatigue management is from person to person. It also gives weight to the importance of having some kind of autoregulation system with your clients to make sure you are getting the most out of your training.
