The Claim
Sodium bicarbonate at a dosage of 0.3 g/kg body weight has no significant effect on muscular endurance during six sets of chest press or knee extension performed at 70% of one-repetition maximum in young, resistance-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 0.3 grams per kilogram of body weight does not increase muscular endurance during six sets of chest press or knee extension at 70% of maximum strength in young adults who regularly lift weights.
See the scientific wording
Sodium bicarbonate at 0.3 g/kg body weight does not significantly improve muscular endurance during six sets of chest press or knee extension at 70% of one-repetition maximum in young, resistance-trained adults, despite its known buffering capacity in high-intensity aerobic tasks.
During resistance exercises like chest presses and knee extensions at 70% of maximum strength, muscles produce hydrogen ions too slowly for them to build up enough to lower pH significantly. Because there is not enough acid to neutralize, extra bicarbonate in the blood does not change how long the muscles can keep working.
What the research says
1 studyScientists tested if baking soda helps people do more push-ups and leg extensions, and found it didn’t. Even though it helps in running or cycling, it didn’t help with weightlifting in this study.
