Abstract:
Background: Neurodynamics intervention is known to increase apparent muscle
extensibility, but information regarding hamstring responses after a neurodynamic sliders (NS)
technique is scarce. The aim of this study was to evaluate the effects of NS on apparent hamstring
extensibility and activity in footballers with hamstring tightness.
Methods: Forty eligible healthy male footballers with hamstring tightness were each
randomly allocated to either a 4-week NS technique or a control group (CG) receiving placebo
shortwave intervention. Knee extension angles were measured with the passive knee extension
test, and maximal voluntary isometric contraction (MVIC) of hamstrings was measured by a
surface electromyography at baseline and after intervention sessions.
Results: The results showed that NS produced a statistically and clinically significant
increase in knee extension angle compared to CG (P < 0.001); however, there was no difference
between the groups receiving MVIC of hamstrings. Within group comparison, NS also provided a
significant increase in knee extension angle (P < 0.001), whereas the control group did not. There
was no change in hamstring MVIC in either group after intervention.
Conclusions: The findings of this study reveal that four weeks of NS technique improved
apparent hamstring extensibility but did not change the hamstring activity in footballers with
hamstring tightness.
