The Claim
In elite race walkers undergoing 3 weeks of intensified training, maximal aerobic capacity (VO2max) increases by 3–7% regardless of dietary intervention, indicating that improvements in aerobic fitness can occur independently of carbohydrate availability when energy intake is sufficient.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Even if elite race walkers don't change their diet, their stamina can still improve after a few weeks of intense training, as long as they're eating enough calories.

What the research says
1 studyThe study found that elite race walkers improved their aerobic fitness after 3 weeks of training, even when eating very few carbs, as long as they got enough total energy. This supports the idea that carb intake isn’t needed for fitness gains if you’re eating enough overall.
