Baking Soda + Sprints: The Dose That Beat Placebo on Every Test
A new randomized trial in basketball players found that adding sodium bicarbonate (baking soda) to four weeks of sprint interval training beat placebo on jumping, sprinting, agility, Yo-Yo distance and Wingate power. The higher dose of 0.45 g/kg then outperformed 0.3 g/kg on every single measure. That makes it a cheap, tempting add-on for team-sport athletes. But the stomach is the catch, and the study is small, short and male-only. Here's the dose math, the GI-distress workarounds, and who this actually applies to.
The Glutamine Dipeptide That Kept Shooters Accurate When Water Didn't
Water is the default hydration advice, but a small study of Division I basketball players suggests it may not protect shooting accuracy as well as water with a little L-alanyl-L-glutamine. Ten women played four 40-minute games, and the low dose of 1 g per 500 ml beat water by 11.1% on shooting. The higher dose did not do better on shooting, and jump power didn't change at all. Here are the numbers, the practical takeaways, and the caveats you should weigh before stirring any of it into your bottle.
