The aim of this study was to investigate the acute effects of whole-body vibration exercises (WBVE) in different positions on muscular activity of flexor digitorum superficialis (FD), wrist extensor (ED), and handgrip strength (HG) of healthy men. Fifteen participants have performed 5 test sets each one consisting of HG strength measurement and 1-minute WBVE intervention (frequency: 50 Hz, amplitude: 1.53 mm, synchronous tri-planar oscillating/vibratory platform), that could be control (no exposition to vibration), squat (30 seconds of rest and 30 seconds of WBVE in squat position), or push-up (30 seconds of rest, and 30 seconds of WBVE in push-up position). After testing, participants had 2 minutes of rest and then were encouraged to keep themselves on a pull-up bar for 30 seconds. During all procedures, muscular activity of FD and ED was measured by surface electromyography (EMG). Statistical analysis has revealed that the EMG measured in the FD during the static pull-up bar exercise after SQUAT condition was significantly higher ( P = .004) than the CONTROL and PUSH-UP conditions. Whole-body vibration exercises in squat position increase acutely muscle activation of the FD during isometric exercises of longer duration, while muscle activation of ED and HG strength are not affected by WBVE.

Abstract The purpose of this study was to analyze the acute effect of whole body vibration exercise (WBVE) on clinical parameters and blood values in horses. Seven horses were exposed to a 10 min WBVE at a frequency of 15-21 Hz. Clinical parameters and venous blood samples were taken before and directly after WBVE. Acute short-term WBVE produced a decrease in serum cortisol (p=0.02) and creatine-kinase (p=0.02) values. Clinical parameters, hematology, fibrinogen, lactate, IGF-I, GGT, creatinine, myeloperoxidase activity and bone marker values were not significantly changed by WBVE. In adult sound horses WBVE was well tolerated and did not cause any sign of measured discomfort.

Whole body vibration affects neuromuscular systems through the stimulation of receptors in muscles and tendons. This study investigated the acute effects of different training intensities of WBV on knee joint proprioception. A total of 18 untrained males participated in this study. Joint position sense was tested as an index of joint proprioception ability. Frequencies of 20, 35, and 50 Hz with two mm of displacement vibration training were tested. Each frequency was tested in different numbers of sets (four, six, eight, and ten sets). As it turned out, the results indicated a significant improvement in active JPS at 35 Hz for all testing sets, and only at 20 Hz with ten sets. As for passive JPS, significant improvements were obtained only at 35 Hz with ten sets of training. WBV training affected knee joint proprioception in active JPS with shorter vibration exposure at lower frequencies and amplitude. Coaches, athletes and physical therapists should consider using WBV training for its potential benefits in warm-ups and rehabilitation.
