Summary

This study aimed to compare the acute effects of proprioceptive neuromuscular facilitation (PNF) and static stretching on hamstring-to-quadriceps (H/Q) strength ratios in healthy young men. A randomized crossover design was used in which participants completed both stretching protocols on separate days. Isokinetic muscle strength and H/Q ratios were assessed following each intervention. The findings provide insight into the immediate effects of different stretching modalities on muscle balance and performance.

Interventions

OTHER

PNF Stretching

Participants performed four repetitions of PNF stretching consisting of a 6-second isometric hamstring contraction at approximately 60% of maximal voluntary contraction followed by a 30-second passive stretch. Rest intervals were standardized.

OTHER

Static Stretching

Participants performed four repetitions of static hamstring stretching, each lasting 30 seconds, with 30-second rest intervals between repetitions.
