Two Stretching Treatments for the Hamstrings: Proprioceptive Neuromuscular Facilitation Versus Kinesio Taping

Che-Hsiu Chen, Tsun-Shun Huang, Huei-Ming Chai, Mei-Hwa Jan, and Jiu-Jenq Lin


Recent studies have shown that the static stretch (SS) may adversely affect leg-muscle performance.


The authors examined the short-term effects of 2 stretching exercises on hamstrings muscle before and after exercise.






9 healthy, physically active men.


There were 3 protocols in a randomized order with a 7-d interval: nonstretching (CON protocol), hamstrings static stretching (SS) with proprioceptive neuromuscular facilitation (PNF), and SS with kinesio-taping application on the hamstrings.

Main Outcome Measures:

Outcome measures included first-felt and maximum tolerant-felt range of motion (FROM and TROM), maximal knee-flexion peak torque (PT) at 180°/s, and hamstrings muscle stiffness.


Groups were not different at prestretching in terms of hamstrings flexibility, PT, and muscle stiffness. At poststretching, both stretching protocols showed significant increases in FROM and TROM (P < .05). Stiffer hamstrings muscle and decreased PT were found in both SS+PNF and CON protocols (P < .05). However, there was no significant difference in the SS+Taping protocol (P > .05).


The stretching protocols improve hamstrings flexibility immediately, but after exercise hamstrings peak torque is diminished in the SS+PNF but not in the SS+Taping group. This means that SS+Taping can prevent negative results from exercise, which may prevent muscle injury.

Activity Distribution Among the Hamstring Muscles During the Nordic Hamstring Exercise: A Multichannel Surface Electromyography Study

Jozef J.M. Suskens, Gustaaf Reurink, Johannes L. Tol, Gino M.M.J. Kerkhoffs, Edwin A. Goedhart, Huub Maas, and Jaap H. van Dieën

Hamstring injuries are the most prevalent muscle injury and are especially common in sports that involve high-speed running, with the biceps femoris most frequently affected. 1 – 6 The 12-weeks Nordic hamstring exercise (NHE) intervention is currently the best evidence-based preventive

Difference of Hamstring Activity Between Bilateral and Unilateral Nordic Hamstring Exercises With a Sloped Platform

Toshiaki Soga, Taspol Keerasomboon, Kei Akiyama, and Norikazu Hirose

Hamstring injury commonly occurs during many sports activities. For instance, many of acute muscle injuries during the Rio Olympic Games were hamstring injuries. 1 Furthermore, the recurrence rate of hamstring injuries is high (>50%). 2 Therefore, prevention of the initial hamstring injury and

Its inclusion as an injury prevention exercise is supported due to its ability to greatly reduce hamstring injuries. 6 For example, in elite soccer players, high levels of eccentric hamstring strength have been shown to reduce the risk
