ADDITION OF SYNCHRONOUS WHOLE-BODY VIBRATION TO BODY MASS RESISTIVE EXERCISE CAUSES LITTLE OR NO EFFECTS ON MUSCLE DAMAGE AND INFLAMMATION

Hazell, TJ, Olver, TD, Hamilton, CD, and Lemon, PWR. Addition of synchronous whole-body vibration to body mass resistive exercise causes little or no effects on muscle damage and inflammation. J Strength Cond Res 28(1): 53-60, 2014-The purpose of this study was to determine if a moderate intensity whole-body vibration (WBV) body mass resistive exercise session causes additional muscle damage, soreness, and inflammation compared with the same exercise session without vibration (NoV). Ten recreationally active male university students completed 2 separate 24-hour study periods incorporating an exercise session with WBV or NoV. Muscle torque was measured (at 0, 60, and 240 degrees s(-1) angular velocities), soreness (10-point scale) in the upper (UE [triceps]) and lower (LE [quadriceps]) extremities, and muscle inflammation markers (interleukin [IL]-1 beta, IL-6, IL-10) were measured at 4 time points (preexercise, immediately postexercise, 4 hours post, and 24 hours post). Diet was controlled. Compared with NoV, WBV increased (p < 0.01) muscle soreness at 24 hours postexercise in both the UE (2.2 +/- 1.7 vs. 0.6 +/- 0.9) and LE (2.0 +/- 1.5 vs. 0.7 +/- 0.7). Muscle torque was decreased immediately postexercise (p < 0.05) in the UE and LE at 0 degrees.s(-1) and in the UE at 240 degrees s(-1), but there was no difference between exercise treatments. The exercise session caused significant but small increases in IL-1 beta and IL-6 but with no differences between exercise treatments. Interleukin-10 was increased with WBV (2.9 +/- 2.0 to 3.6 +/- 1.9 pg.ml(-1); p < 0.03). These data suggest that the addition of WBV to exercise has little effect on muscle function and damage, soreness, or inflammation.
