Which stretch wins? study tests PNF vs. static stretching for muscle balance
NCT ID NCT07589712
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how two different stretching techniques—PNF and static stretching—affect the strength balance between hamstrings and quadriceps in 23 healthy young men. Each participant tried both stretches on separate days, and their muscle strength was measured right after. The goal was to see which method might be better for muscle balance and performance.
