About this study
Official title: Effectiveness of Focal Vibration in Enhancing Lower Extremity Speed and Power in Athletes
A focal vibration device will be used to perform an activation and warm-up protocol before performing a set of 7 repetitions of squat with 60% of your 1RM.
- Being tested
- Focal Vibration, Sham focal vibration
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Focal VibrationOther
Also called Local Vibration
Focal vibration is a 3x3 electrode placed on the athlete's muscle belly, and emits a high frequency vibration (150Hz) to stimulate the muscle spindle and generate greater muscle activation.
Sham focal vibrationOther
Is a focal vibration intervention but without conctact in the athelte's skin. Doing this we got a sham therapy
| Study group | Role | What they receive |
|---|---|---|
| Vibration group | Experimental | The vibration group receives an intervention with focal vibration heads from Wintecare on the rectus femoris, vastus lateralis and vastus medialis , at the same time that the athelte is doing active muscle contractions. Receives: Other: Focal Vibration |
| Sham group | Sham comparator | The placebo group receives the same protocol but the head of the focal vibration machine is not in contact with the patient's skin. Receives: Other: Sham focal vibration |
What is being measured
The primary outcome is the main question the study is designed to answer.
Mean Speed during squat
A linear transducer (Vitruve VBT) was used to measure the mean speed during the squat. The tether device was attached to the right side of the barbell around the widest part of the collar on the inside and this converts the subject's movement with the barbell into an electrical signal that will record the mean speed and of the exercise. Subjects will per-form 7 repetitions at 0,85 m/s at the maximum possible speed with the optimal load to generate the maximum power.
Linear transducers which have greater accuracy (5%) and reliability (ICC: 0.752; 95% CI: 0.548 - 0.855) compared to other devices in terms of velocity-based training (VBT) meas-urement.
Measured: 1 minute
Mean Power during squat

Measured: 1 minute
Secondary outcomes (3)
Scale of perceived effort during squat
Just after the end of the series of 7 repetitions the sensation of effort perceived by the athlete was measured with the modified BORG scale (0-10), being 0 the lowest perceived effort and 10 being the highest effort.
Measured: 1 minute
Participant's rating of clinical change. Global Rating of Change Scale (GROC scale).
At the end of the free bar squat after the warm-up and the intervention, the subject will be asked if he/she has felt improvement or worsening between the first time and the last time he/she performed the test. The participant's rating of clinical change will be evaluated with a Global Rating of Change Scale (GROC scale). This is a scale of 15 items, of which +7 are improvement and -7 are deterioration, and with 1 central item with no clinical change. Values from the fourth item of improvement or deterioration will be considered clinically significant, values between the three item of improvement and the three item of deterioration will be considered as no clinically significant changes. The test-retest reliability has proven to be good (ICC 0.90).
Measured: 1 minute
Muscle Activity
Surface electromyography was used to evaluate the muscle activity of back and lower limb the during squatting task. The muscles assessed were vastus medialis, vastus lateralis, rectus femoris, biceps femoris, gluteus maximus and erector spinae longissimus. Data were obtained for the dominant limb defined as the one preferred to kick a ball.
the tool to be used is The mDurance® system (mDurance Solutions SL, Granada, Spain). The RMS was the principal variable recorded for muscle activity, expressed as % of MVIC (%MVIC).
Measured: 1 minute
