CSA: cross‐sectional area; fCSA: fibre cross‐sectional area; Integrated MyoPS: myofibrillar protein synthesis considering the first 48 h (i.e. 0–48 h) after a single resistance exercise bout; Z‐band streaming (overall): calculation that took into account the total amount of area with Z‐band streaming divided by total area analysed at T1, T2 and T3 altogether; VL: vastus lateralis; T1: first week, T2: third week, T3: last week of training. *Significant (P < 0.05) correlation. aHigh correlation between variables.
