12 trained cyclists, 2h ride, 65g carbs vs 65g carbs and 19g protein per hour
performance between trials was similar, protein has no effect on performance when consumed during
CHO vs CHO-PRO vs CHO-CHO, 90min run, 4 h recovery then run to exhaustion
additional carbs or protein enhanced glycogen resynthesis (Betts et al 2007)
if a suboptimal amount of carbs is ingested, then does protein increase muscle glycogen synthesis?
yes, but if optimal carbs is ingested, then protein doesnt contribute further, but its more realistic to use carbs and protein
hydration post exercise: 65g/L carbs vs 40g/L and 25g/L milk protein - which is better?
milk protein helps enhance rehydration
What happens to protein synthesis responses (FSR mitochondria and myofibrillar)?
they become exercise specific - increase in plasticity (continuous breakdown and synthesis), more responsive - proof of adaptive response specific to chronic training
CHOPRO, CHO and PLA (placebo) drinks on adaptation for endurance exercise
CHOPRO intake 1h after each session enhances adaptation - more protein = more mitochondria = higher ATP turnover = increased VO2 max
What effect does alcohol have on MPS?
when consumed in vast amounts, alcohol can reduce MPS
