Representative picture of the experimental set up.
The participant is performing a squat exercise in the condition currently adopted for healthy subjects in fitness centers.
Table 1.
Unloaded configuration for actual vibration characteristics (frequency, peak-to-peak displacement and peak acceleration) measured by accelerometer.
Fig 3.
Individual pattern of O2(AUC) in the 22 participants over the whole training session (Sets A-C) in the presence (open triangle) and absence (open circles) of vibration (~56Hz, ~11g). Mean value is indicated by filled symbols. I-VI, sequential exercises (see text); R, between-exercise recovery time. R*, sum of between-exercise and between-set recovery time. Data are adjusted by individual peak acceleration and order of treatment administration (WBV/no vibration vs. no vibration/WBV).
Table 2.
WBV-associated changes in several outcome measurements in a group (n = 22) of exercising male participants.
Data are mean±SD.
Fig 4.
Individual percent reduction (Δ) of O2 consumption in the 22 participants during total recovery time (6.5min) along a 20-min training session in the presence (WBV) or absence (no vibration) of whole body vibration.
Δ was significantly higher in the presence of WBV. Data are adjusted by peak acceleration and order of treatment administration (WBV/no vibration vs. no vibration/WBV).
