The Claim

The performance decline observed in elite female U20 footballers during an intense 3-week training camp is associated with lower baseline YoYo IR1 performance resulting from accumulated fatigue following a prior competitive season.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

Elite female football players under 20 showed reduced performance during a 3-week training camp, and this reduction was linked to lower initial fitness levels caused by fatigue from their previous competitive season.

See the scientific wording

The performance decline observed in elite female U20 footballers during an intense 3-week training camp may be due to accumulated fatigue from a prior competitive season, as baseline YoYo IR1 performance was lower than previously reported in elite female footballers.

Why this might work

After a long season of intense play, muscles lose their ability to use oxygen efficiently and the brain's signals to activate muscles weaken, making it harder to run hard even before a new training camp starts.

    The study found that teenage female footballers got 7.4% worse at a running test after three weeks of tough training — and they started the training already slower than usual, suggesting they were already tired from their previous season.
