boosting the effects of exercise in adults. Methods We devised a 5‐week climbing exercise
scheme with food reward administered to male juvenile rats (post‐natal week 4–9).
Subsequently, the animals were subjected to 10 weeks of detraining (week 9–19) without
climbing and finally retraining during week 19–21. Results The juvenile exercise increased
fiber cross‐sectional area (fCSA) by 21%(p= 0.0035), boosted nuclear accretion by 13%(p …
