This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether sodium bicarbonate—a common dietary supplement made from baking soda—can help competitive fin swimmers perform better and feel less fatigued during races. Researchers will give participants either the medication or a look-alike placebo pill before a 200-meter fin swimming race, and measure how it affects their speed, how their muscles feel, and their blood chemistry.
During intense swimming, muscles produce acid that can make them feel tired and slow you down. This medication is thought to help reduce that acid buildup, but no one has carefully studied whether it actually works for fin swimmers specifically.

You will visit the pool on three separate occasions, spaced 48 hours apart with no training between visits. At each visit, you'll take either a capsule containing the medication, a placebo, or no supplement at all (in random order), then warm up and swim a timed 200-meter race. Researchers will take small blood samples before, during, and after each test to measure muscle fatigue markers, and they'll ask you to rate how hard the effort felt.
