The Claim
In sprint-trained athletes, plasma ammonia and blood lactate concentrations are significantly elevated, and blood pH is significantly reduced during the one-hour recovery period following a 30-second maximal sprint, when compared to endurance-trained athletes, suggesting a greater metabolic disturbance in sprint specialists after high-intensity exercise.
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.
After a super intense 30-second sprint, sprint athletes have higher levels of certain chemicals in their blood and more acidic blood than endurance athletes during recovery — which means their bodies go through a bigger metabolic shake-up.
See the scientific wording
Plasma ammonia and blood lactate concentrations are higher, and blood pH is lower, during the one-hour recovery period after a 30-second maximal sprint in sprint-trained athletes compared to endurance-trained athletes, indicating greater metabolic disturbance in sprint specialists following high-intensity effort.
What the research says
1 studyStudy: Growth hormone responses to treadmill sprinting in sprint- and endurance-trained athletes
The study had sprint and endurance athletes do a short, all-out sprint and then checked their blood during recovery. Sprint athletes had higher ammonia and lactate levels and lower blood pH, just like the claim says.
