What the study found

Points to benefit

Recovery of strength, soreness, leg-raise range and blood myoglobin was greater with cold water than rest. Soreness fell by 15.4 ± 1.5 mm on day two (p < 0.000).

How much this study counts

  • ✓Randomized: people were put into groups by chance, so the groups start out alike.
  • –Small: 18 people. Small trials can miss real effects or find chance ones.
  • –Short: 1 week. Longer-term effects are unknown.
  • •Measured several kinds of outcomes.
  • ✓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.
