PNF BETTER THAN STATIC STRETCHING POST-EXERCISE
Funk, D. C., Swank, A. M., Mikla, B. M., Fagan, T. A., & Farr, B. K. (2003). Impact of prior exercise on hamstring flexibility: a comparison of proprioceptive neuromuscular facilitation and static stretching. Journal of Strength and Conditioning Research, 17, 489-492.
This study compared FIVE minutes of static stretching and proprioceptive neuromuscular facilitation (PNF) on hamstring flexibility performed with and without exercise. Undergraduate student-athletes (N = 40) participated in a repeated measure, counterbalanced experimental design.
PNF resulted in a significant increase in flexibility after 60 minutes of exercise when compared with baseline (9.6%) and without exercise (7.8%). No differences were observed with static stretching across time. In addition, no differences were observed between the groups at any time point.
Implication. Results demonstrated that PNF performed after exercise enhanced acute hamstring flexibility, and implementing a PNF stretching routine following exercise may augment current stretching practices among athletes.
