Fig. 2From: Effects of a 4400 km ultra-cycling non-competitive race and related training on body composition and circulating progenitors differentiationSestrins increased after the training (b, BN) while NC4000 performance (c, AN) restored their protein levels. MyoD levels increased after the training (b, BN) and NC4000 performance (c, AN). SIRT1 levels increased in cells cultured in the presence of sera collected in subjects after the training (b, BN) and NC4000 performance (c, AN). a (BPP, before the preparation period); b (BN, the week before NC4000); AN (c, 10 days after NC4000). *p < 0.05; **p < 0.005Back to article page
