“…In conclusion, the current study showed that static squat position with different muscle length of plantar-flexors during 26 Hz WBV did not affect jumping heights compared with the no-WBV condition. Practically, lower frequencies (20-30 Hz) (Cardinale & Lim, 2003), 90º squat position (Avelar et al, 2013;Tsukahara et al, 2016) with heels raised (Di Giminiani et al, 2013) maximizes muscle activity and vibration effect, but squat position with or without heels raised has no effect on jump performance. Besides that WBV affects acute jump performance regardless of short or long muscle length during WBV.…”

“…Some studies focused on body position during WBV. According to these studies, knee flexion of 90º during WBV is associated with a greater magnitude of vibration to the calf compared to the knee flexion of 30º, and 90 º squat position may be useful for conducting vibration to the calf (Tsukahara et al, 2016). Abercromby et al (2007) indicated that static squat position caused higher meuromuscular responses compared to dynamic squatting.…”

Background. The aim of the study was to investigate the acute effect of whole-body vibration (WBV) during heel raised and standing squat position on squat (SJ) and countermovement jump (CMJ) heights.Methods. Twenty four physically active sport science students are voluntarily participated in this study. Randomized, counterbalanced, crossover study was used in this study and all subjects completed two trials that were plantar (25-30°) and dorsal (5-10°) flexion squats. WBV exercises were performed on a vibration plate at 26 Hz frequency, 4mm amplitude. Jumping performances were assessed with and without WBV conditions. Subjects executed WBV condition treatment on static plantar or dorsal flexion half squat position (45°knee angle) for 3x60 s with 60 s rest between sets.Results. There was no statistically significant two-way interaction between treatments and times for SJ and CMJ (p > .05). SJ and CMJ after the WBV were significantly higher than without WBV condition (p < .05). SJ and CMJ heights were higher than baseline values without WBV.Conclusion. These results indicate that there were no differences between WBV during plantar and dorsal flexion squat position on SJ and CMJ heights. Regardless of different muscle length squat position during WBV, there were little but significant differences (~1cm) on SJ and CMJ heights after WBV. According to these results it can be said that WBV had a statistically significant acute effect on jumping, but different plantar-flexor muscle length squat position on vibration plate during WBV did not have any effect on jumping performance.

“…It is already known that WBV achieves positive effects on the neuromuscular system, such as strength, EMG signal, muscle activation, performance, induces increased blood concentrations of testosterone and growth hormone, improves muscle dynamics, muscle activation, dynamic joint stability, coordination and proprioception, muscle fatigue and joint mobility (4,11,16,19,20,(38)(39)(40)(41)(42). Due to these benefits, this technology has been tested in different audiences, such as athletes, in this case.…”

“…The intervention protocols were varied, however, most publications coincide with good results when using 30 Hz Acute Effects of WBV on Muscle Strength in Subjects with Shoulder Instability of frequency, a single session (acute effects), 3 series of stimulation, using the isometric arm flexion position with the hands on the platform. A single session of WBV application has shown positive results on the neuromuscular system and has been used as a protocol in several studies (5,(13)(14)(15)(16)(17)(18)(19)(20). Within the WBV studies, there are also those who investigated the effects of this technology on joint instabilities.…”

Background. Whole-body vibration (WBV) has proven to be an efficient tool in improving the physical qualities of the neuromuscular system, such as increasing muscle strength, performance, joint stability, electromyographic signal, proprioception, among others. Its use in the upper limbs and joint instabilities has shown good immediate results in a single session. The aim of this study was to analyze the acute effects of the use of mechanical vibration on the muscle strength of subjects with shoulder instability. Methods. 10 athletes in the process of post-surgical rehabilitation of shoulder instability were volunteers in this study. Muscle strength was tested in the internal (IR) and external (ER) rotation movements in the neutral position using isokinetic dynamometry at two angular velocities -60 and 180º/s in three moments: before, immediately after, and 10 minutes after the application of WBV. The WBV was applied only once, using a frequency of 30 Hz, with the patient assuming the arm flexion position on the platform during 5 series of 30 seconds of stimulation. Results. The limb with shoulder instability benefited in both movements -ER and IR and in both angular velocities. The limb without instability, on the other hand, had increased strength only in the RI movements at 60º/s and RE at 180º/s. Conclusions. It is concluded that a single session of WBV applied directly to the upper limbs is capable of acutely improving muscle strength in both limbs in subjects with shoulder instability, with the affected limb being the most benefited.

“…Secondary effects were not considered for the lab-based testing interventions because of a focus on the primarily vibration-related neuromuscular effects. The transmission of vibrations also depends on arm or body posture (38,39). An unintentional optimization of the seating position, such as changing the trunk posture to minimize the transmission of vibrations, can also influence muscular activation.…”

Purpose: This study aimed to provide an understanding of how surface-induced vibrations in cycling interfere with short-term neuromuscular performance. Methods: The study was conducted as a cross-sectional single cohort trial. Thirty trained cyclists participated (mass = 75.9 ± 8.9 kg, body height = 1.82 ± 0.05 m, V ˙O2max = 63 ± 6.8 mL•kg −1 ⋅min −1 ). The experimental intervention included a systematic variation of the two independent variables: vibration (Vib: front dropout, 44 Hz, 4.1 mm; rear dropout, 38Hz, 3.5 mm; NoVib) and cranking power (LOW, 137 ± 14 W; MED, 221 ± 18 W; HIGH, 331 ± 65 W) from individual low to submaximal intensity. Dependent variables were transmitted accelerations to the body, muscular activation (gastrocnemius medialis, gastrocnemius lateralis, soleus, vastus lateralis, vastus medialis, rectus femoris, triceps brachii, flexor carpi ulnaris, and lumbar erector spinae), heart rate, and oxygen consumption. Results: The main findings show that the root-mean-square of local accelerations increased with vibration at the lower extremities, the torso, and the arms-shoulder system. The activation of gastrocnemius medialis, gastrocnemius lateralis, soleus, triceps brachii, and flexor carpi ulnaris increased significantly with vibration. The activation of vastus lateralis increased significantly with vibration only at HIGH cranking power. Oxygen consumption (+2.7%) and heart rate (+5%-7%) increased significantly in the presence of vibration. Conclusions: Vibration is a full-body phenomenon. However, the impact of vibration on propulsion is limited as the main propulsive muscles at the thigh are not majorly affected. The demands on the cardiopulmonary and respiratory system increased slightly in the presence of vibration.
