Training adaptation, not beta-alanine supplementation, is responsible for performance improvements in female basketball players over four weeks, as no difference in improvement was observed between supplemented and placebo groups across all performance metrics.

Repeated basketball training strengthens muscle contractions, improves nerve signaling to muscles, and makes the body more efficient at using energy during exercise. These changes make players jump higher, run faster, and shoot more accurately. Taking beta-alanine reduces muscle burn during intense exercise, but this does not make players stronger or faster because the real improvements come from training, not from reducing muscle burn.
