We aimed to compare the effects of low- and high-frequency vertical whole-body vibration training in the static squat position for 3 days/week for 6 weeks on anaerobic power, anaerobic capacity, isometric back and leg strength, and rating of perceived exertion. Subjects were 16 recreationally active men (23.3 ± 3.3) randomly divided into 2 groups: low frequency (25 Hz) group (n = 9) and high frequency (40 Hz) group (n = 7). In the first 3 weeks of the study, we applied whole-body vibration for 5 × 1 minute with 1-minute resting intervals and, in the second 3-week period, for 7 × 1 minute with 40-second resting intervals with 2-mm peak-to-peak amplitude. Anaerobic performances, leg and back strength, and rating of perceived exertion during these performances was measured with the Wingate anaerobic power test, isometric leg strength test, and Borg scale, respectively. Isometric leg and back strength, fatigue index, and rating of perceived exertion were found to be unaffected by either frequency. However, anaerobic performance assessment variables showed that both frequencies improved anaerobic power (peak power and relative peak power) and anaerobic capacity (mean power and relative mean power) (low-frequency group, 0.84 ≤ r ≤ 0.89; high-frequency group, 0.51 ≤ r ≤ 0.64). In conclusion, both frequencies (25 Hz and 40 Hz) increased anaerobic performance variables. The small sample size was the most important limiting factor of this study. Another study with a larger sample size might be more beneficial for achieving more reliable results. © JPES.
