Original title: Cold Water Immersion Does Not Enhance Recovery and Performance After High-Intensity Interval Dorsiflexion Exercise.

Under review. A person has not yet checked this summary against the paper. It is written from the PubMed abstract. Until a person checks it, search engines are asked not to list this page.

What the study found

No difference

Muscle strength stayed lower for up to 3 h in both conditions. A repeat workout 24 h later was similar. 10 minutes of cold water at 10°C did not improve recovery or next-day performance.

How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • –Small: 12 people. Small trials can miss real effects or find chance ones.
  • ✓Measured the question itself: muscle recovery, mood and immune health.
  • ✓No competing interests declared.
  • •Summarized from the PubMed abstract only. The full paper may hold details the abstract leaves out.

✓ Strength– Limit• Note

These points come from fixed rules about the type of study, its size and length, what it measured, and who has a stake. Every study on Digestery gets the same rules.
