The Claim

In young men, six weeks of sprint training reduces the post-exercise plasma ammonia response, with mean peak ammonia decreasing from approximately 184 to 139 μmol/L.

Cause and effect
1 study reviewed
In plain English

Young men who sprint-trained for six weeks had lower ammonia levels in their blood after exercise. Ammonia is a waste product your muscles make when you work out hard. Levels dropped from about 184 to 139.

See the scientific wording

Six weeks of sprint training reduces the post-exercise plasma ammonia response in young men, with mean peak ammonia decreasing from about 184 to 139 μmol/L.

Why this might work

When you sprint, your muscles break down a fuel called ATP very quickly. This process makes a waste product called ammonia. Six weeks of sprint training makes your muscles better at making ATP and at removing ammonia, so after training, your muscles release less ammonia into your blood. That means your blood ammonia levels stay lower after a sprint.
