Question
![Blood lactate is a biochemical by-product that is produced during high-intensity exercise
due to insufficient oxygen intake. Commercially available drinks advertised as oxygen sup-
plements claim to increase exercise performance and decrease the postexercise recovery
period by decreasing the accumulation and accelerating the removal of blood lactate.
To test this claim, researchers conducted a controlled experiment to compare the concen-
tration of blood lactate during exercise and during recovery between two participant
groups, one that ingested oxygen-supplemented water and another that ingested regular
water.
