What changes

Dynamic warmups are commonly associated with a 2–5% relative improvement in acute sprint performance versus static-only routines.

When this tends to work

• Conditions similar to: Collegiate and amateur field athletes, acute session studies
• You can measure 20-meter sprint time reliably
• The intervention is implemented consistently, not half-measured

When to be careful

• Your audience or product differs materially from the cited context
• Compliance costs or second-order effects outweigh the lift
• Evidence label is meta_analysis—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
