Previously, we examined the effects of carbohydrate (CHO) ingestion on glucose kinetics during exercise at 70% of maximum O2 uptake ( $$\dot V$$ O2,max). Here we repeat those studies in heavier cyclists (n=6 per group) cycling for 3 h at a similar absolute O2 uptake but at a lower (55% of $$\dot V$$ O2,max) relative exercise intensity. During exercise, the cyclists were infused with a 2-3H-glucose tracer and ingested U-14C glucoselabelled solutions of either flavoured water (H2O) or 10 g/100 ml… CONTINUE READING
