The Claim

In highly conditioned individuals, the rates of performance decline across running, rowing, and swimming are similar, indicating that multiple major physiological systems decline in a coordinated fashion without any single system deteriorating at a significantly faster rate than others.

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.

How it works
1 study reviewed
In plain English

When top athletes get older, their performance drops at about the same rate in running, rowing, and swimming — which suggests their body systems all slow down together, not one faster than the rest.

See the scientific wording

The similarity in performance decline rates across running, rowing, and swimming suggests that multiple major body systems decline in a coordinated manner, with no single system deteriorating significantly faster than others in highly conditioned individuals.

What the research says

1 study
  1. Study: How fast do we age? Exercise performance over time as a biomarker.

    The study looked at how fast top athletes in running, rowing, and swimming slow down as they age, and found they all decline at about the same rate. This supports the idea that our body systems age together, not one faster than the others.
