This sprint workout amounted to just three minutes of hard effort. Even so, it stirred up a reaction in the bloodstream that the hour-and-a-half moderate ride couldn’t come close to.
Researchers used a lab tool that scans nearly 3,000 proteins in a single blood draw. Right after sprinting, 714 had shifted, almost all moving upward, including several tied to building new blood vessels and repairing tissue. By the three-hour mark, most had faded, suggesting the body processes this burst fast and moves on. Moderate cycling barely registered.
Sprinting’s chemical fingerprint showed up in blood chemistry too, not just proteins. More than 200 compounds shifted right after sprinting, including one called Lac-Phe, which earlier research has linked to appetite control and weight regulation.
