Flexibility Enhancement with Vibration

Measurement of angles in time-of-flight data for the automatic supervision of training exercises

“…Several have shown that whole body vibration training has a positive effect on neuromuscular parameters such as maximum strength [6], [7], [8], muscle performance [6], [7] and flexibility [9], [10]. Our own studies [11], [12], [13] confirm this effect and furthermore prove a significant positive influence on pain in the lower back and the quality of life [13].…”

Effects of repeated Achilles tendon vibration on triceps surae stiffness and reflex excitability

“…As reported by several studies with different vibration protocols (Nazarov and Zilinsky, 1984;Issurin et al, 1994;Fagnani et al, 2006;Sands et al, 2006), the tested group was characterized by an enhancement in flexibility, especially with a greater dorsiflexion maximal angle. To understand this flexibility enhancement better, we also analyzed passive stiffness of triceps surae muscles, defined as the slope of the passive torque-articular position relationships.…”

“…Passive tension is often characterized by the measure of flexibility, defined as the range of motion about a joint (Tardieu et al, 1981;Guissard and Duchateau, 2004). After different vibration training protocols, associated or not with stretching exercises, many authors reported an enhancement of articular flexibility (Nazarov and Zilinsky, 1984;Issurin et al, 1994;Fagnani et al, 2006;Sands et al, 2006). To understand these adaptations better, it could be relevant to determine muscle passive stiffness.…”

On the nature of the electromyographic signals recorded during vibration exercise

“…Vibrating dumbbells (Bosco et al 1999), vibrating pulley-like devices (Issurin et al 1994;Issurin and Tenenbaum 1999), and vibrating barbells (Poston et al 2007) have been proposed for the upper limbs. Other devices producing a sinusoidal force-modulated stimulation (Kinser et al 2008;Sands et al 2006;Mischi and Cardinale 2009;Xu et al 2012) have also been shown to acutely enhance strength, power, and flexibility, mainly due to the neuromuscular demands placed by such force modulation on skeletal muscles.…”
