Fig 1. Cyclists (n = 8) were evaluated for: A) average exercise volume per week (min) throughout pre-competitive season (PS) and competitive-season (CS), B) myonuclei per muscle fibre, C) myonuclear domain (μm3/myonucleus) and D) SCs/muscle fibre after pre-competitive season (PRE) and post-competitive season (POST).
* = P < 0.05, ** = P < 0.01, and ##, ++ = P < 0.001 (A: ++, ## indicate differences from corresponding pre-competitive season training zone and race time). Percentage of total time spent training and race in corresponding season is shown in parentheses.
