Outcomes
Primary Outcomes
Mean Speed during squat
Time Frame: 1 minute
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.
