The Claim

Combined beta-alanine and sodium bicarbonate supplementation reduces mean heart rate during submaximal incremental cycling in highly trained female basketball players, indicating improved cardiovascular efficiency during aerobic recovery phases through synergistic intracellular and extracellular buffering that reduces metabolic strain.

How it works
1 study reviewed
In plain English

In highly trained female basketball players, taking beta-alanine and sodium bicarbonate together lowers heart rate during moderate-intensity cycling, reflecting reduced metabolic strain during recovery due to enhanced buffering of acid in cells and blood.

See the scientific wording

Combined beta-alanine and sodium bicarbonate supplementation reduces mean heart rate during submaximal incremental cycling in highly trained female basketball players, suggesting improved cardiovascular efficiency during aerobic recovery phases, potentially due to synergistic intracellular and extracellular buffering that reduces metabolic strain.

Why this might work

Taking both supplements increases the body's ability to neutralize acid inside and outside muscle cells, which prevents the buildup of acid during exercise. This reduces the signal for the heart to beat faster, so the heart works less hard at the same level of effort.

  1. Study: Effects of Combined Versus Isolated Beta-Alanine and Sodium Bicarbonate Supplementation on Physical Capacity in Highly Trained Female Basketball Players: A Randomized Controlled Trial.

    When female basketball players took both beta-alanine and sodium bicarbonate together, their heart rate went down during moderate exercise, meaning their hearts didn’t have to work as hard. This didn’t happen when they took either supplement alone.
