Vibration exposure is known to affect muscle physiology and neuromuscular activity. Research of the effect of whole body vibration on muscle activation has focused on passenger safety in vehicles and on work place safety, for which guidelines and international standards have been developed (ISO 2631). However, in many sports the athlete is also exposed to substantial continuous vibrations (e.g. inline skating, mountain biking, alpine skiing) or recurring impact shocks (e.g. running, soccer, tennis). The later have received some scientific attention, however, there are very few studies investigating the impact of continuous vibration exposure on neuromuscular activity during the execution of a specific movement in sports. The purpose of this study was to quantify simultaneously vibration exposure and muscle activation on four muscles of the lower extremities during alpine skiing.
