The Claim
Supplementation with beta-alanine or sodium bicarbonate has no effect on ratings of perceived exertion in highly trained female basketball players during repeated high-intensity efforts.
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.
Taking beta-alanine or sodium bicarbonate does not change how fatigued highly trained female basketball players feel during repeated high-intensity exercise.
See the scientific wording
Neither beta-alanine nor sodium bicarbonate supplementation affects ratings of perceived exertion in highly trained female basketball players during repeated high-intensity efforts, indicating that performance improvements occur without altering subjective fatigue perception.
When the body works very hard, it produces acid inside muscle cells. Special chemicals in the blood and inside the muscles soak up this acid, keeping the muscle environment less acidic. This lets the muscles keep pushing hard for longer without getting tired faster, but the person doesn’t feel like they’re working any harder than before.
What the research says
1 studyThe study found that when female basketball players took sodium bicarbonate, they could sprint harder without feeling any more tired than before. Beta-alanine didn’t help, but the bicarbonate did — and still, they didn’t feel more exhausted. So yes, they got stronger without feeling like they were working harder.
