@pwftraining: PMID: 30663816 gives us a good idea of damage and recovery to certain muscles and this can definitely be useful information to apply to your programming. It would make sense for the Chest and arms to be easily damaged, since we can’t really not train them in relatively lengthened positions. However, we do need to keep in mind that how much damage an individual (or a certain muscle group) will experience can vary depending on things like length-tension relationship and fiber type ratio. Why Fiber Type Ratio?: FTR can affect whether or not certain muscles will be more susceptible to damage. Type 1 Fibers have more mitochondria while type 2 fibers have fewer mitochondria. Mitochondria play a large role in regulating calcium levels within the cytoplasm and calcium ion influx / the release of calpains is the muscle damage that we’re talking about here. So if a muscle is more type 2 fiber dominant, it would be more susceptible to damage. Now, this is valuable information that we can use in our programming. However, simply programming properly (or getting someone educated to do it for you) will leave you not having to worry about it so much.
