The Claim
Sodium bicarbonate supplementation at 0.2 g/kg body weight has no significant effect on core temperature, heart rate, or perceptual responses during repeated sprints in 40°C ambient conditions among recreationally endurance-trained adults.
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 sodium bicarbonate at a dose of 0.2 grams per kilogram of body weight does not change core body temperature, heart rate, or how hot or uncomfortable people feel during repeated sprinting in 40°C heat.
See the scientific wording
Sodium bicarbonate supplementation at 0.2 g/kg body weight does not significantly alter core temperature, heart rate, or perceptual responses to heat stress during repeated sprints in 40°C ambient conditions among recreationally endurance-trained adults, indicating it does not exacerbate thermoregulatory strain under these conditions.
Taking sodium bicarbonate increases bicarbonate in the blood, which neutralizes acid produced during intense exercise. This allows muscles to work harder without getting as fatigued, but it does not change how hot the body gets, how fast the heart beats, or how hard the person feels the effort in hot conditions.
What the research says
1 studyTaking sodium bicarbonate before intense exercise in hot weather didn’t make people any hotter or put more stress on their body’s cooling system than taking a placebo — even though they performed better.
