Abstract

Purpose: The purpose of this study was to evaluate the effects of a new high-intensity training modality comprised of vibration exercise with superimposed resistance exercise and vascular occlusion (vibroX) on skeletal muscle and performance.

Method: Young untrained women were randomized to either train in a progressive mode on 3 days per week for 5 weeks ( N=12) or to maintain a sedentary lifestyle ( N=9). VibroX increased peak cycling power (+9%, P=0.001), endurance capacity (+57%, P=0.002), ventilatory threshold (+12%, P<0.001), and end-test torque (+15%, P=0.002) relative to the sedentary group.

Results:

• Training load increased by 84.5% ( P<0.001) after vibroX.
• The increases were paralleled by increases in myosin heavy chain type 1 vastus lateralis muscle fiber cross-sectional area (+14%, P=0.031) and proportion (+17%, P=0.015), thigh lean mass (+4%, P=0.001), capillary-to-fiber ratio (+14%, P=0.003), and cytochrome c oxidase activity.
• Conversely, maximal values for oxygen consumption, cardiac output, isokinetic leg extension power and jumping power remained unaffected.
• Notably, vastus lateralis muscle adaptations were achieved with a very low weekly training volume.

Conclusion:  We conclude that vibroX quickly increases muscle (fiber) size, capillarization, and oxidative potential, and markedly augments endurance capacity in young women.

Method: Young untrained women were randomized to either train in a progressive mode on 3 days per week for 5 weeks ( n = 12) or to maintain a sedentary lifestyle ( n = 9).

Results: VibroX increased peak cycling power ( + 9 % , P = 0.001), endurance capacity ( + 57 %, P = 0.002), ventilatory threshold ( + 12 % , P < 0.001), and end-test torque( + 15 % , P = 0.002) relative to the sedentary group. Training load increased by 84.5 % ( P < 0.001) after vibroX. The increases were paralleled by increases in myosin heavy chain type 1 vastus lateralis muscle fiber cross-sectional area ( + 14 %, P = 0.031) and proportion ( + 17 % , P = 0.015), thigh lean mass    ( + 4 % , P = 0.001), capillary-to fiber ratio ( + 14 % , P = 0.003), and cytochrome c oxidase activity. Conversely, maximal values for oxygen consumption, cardiac output, isokinetic leg extension power and jumping power remained unaffected. Notably, vastus lateralis muscle adaptations were achieved with a very low weekly training volume.

Conclusion: We conclude that vibroX quickly increases muscle (fi ber) size, capillarization, and oxidative potential, and markedly augments endurance capacity in young women.
