- Abstract
This study compared the acute responses of ROMmax, Torquemax, ROMfss, Torquefss, Stiffness, and Energy in the static passive hamstrings stretching, hamstrings mechanical vibration, and a combination of both. Twelve male subjects (mean ± SD, age 22.3 ± 1.9 yr, height 176 ± 3 cm, mass 77.3 ± 9.0 kg) not trained in flexibility volunteered to participate in this study. The study was a latin square design with all subjects completing four conditions: (a) control (CON); - no intervention; (b) stretching (ST) - 4 x 30 sec passive static stretching of the hamstrings muscle to 90% of ROMmax; (c) vibration (VIB) - 4 x 30 sec bouts of vibration applied to the hamstring muscle; and (d) Stretching with vibration (ST+VIB) - a combination of the stretching and vibration protocols. Variables performance were assessed using a Flexmachine prior to and after experimental conditions. The results showed no significant difference between the conditions for ROMmax, Torquemax, ROMfss and Torquefss (P>0.05). There was a significant decrease in ST between baseline and after intervention for Stiffness (P = 0.007) and Energy (P = 0.0024). Conventional training and the use of vibration, as specified in this study, did not enhance the subjects' adaptations to flexibility training. However, for Stiffness and Energy, conventional training seems to reduce both when compared to mechanical vibration.
