Macro partitioning
Optimizing within-day carbohydrate distribution is critical for rugby players with congested schedules, as inadequate post-training carbohydrate intake may compromise substrate availability for subsequent evening sessions.
For rugby players training twice a day, when you eat carbohydrates matters as much as how much. The study showed that despite intervention, players didn't improve their post-morning training carb intake, and actually ate less carbs later in the day. This suggests that without specific guidance, athletes may neglect refueling between sessions, potentially impacting evening performance. Prioritize quick carbs immediately after morning training to fuel the evening session.
Inadequate carbohydrate consumption following the morning training session on high-volume days may compromise the availability of substrates during the evening session... Immediate consumption of carbohydrates post-exercise results in greater muscle glycogen repletion than delayed feeding
Why this rating
Based on general sports nutrition principles cited in the discussion, not a primary outcome of the intervention which failed to change carb timing significantly.
