Also, the first weeks of training in any rep range or intensity level is going to be a neural DISinhibition and an upregulation in storage substrate and transport systems.
In other words efficiency tactics are employed befofe spending the energy on actually adding tons of sarcomeres. Contractile strength increases, fuels are increased and the ability to extract and exchange increases. Its much more complex but people are really only adding fluid and storage volumes and not actually packing on tons of muscle...yet.
This is likely why its "favorable" from a stress response as shown in the studycompared to even an intermediate strength trainer, in beginners even the stress response has yet to be fully adapted. Stresses eventually go from "oh whats this?" to "damn, we need to get better in case this gets worse"
This is also part of the reason vasculature and "pump" really become enhanced as time goes on as capillary and exchange adaptations along with a ton of other things.
