FCC: flexors' concentric contraction
, EEC: extensors' eccentric contraction, ECC: extensors' concentric contraction
, and FEC: flexors' eccentric contraction) at three joints for both groups.
Considering that P2 consists of concentric knee extension, reduced angular velocity during the backward Fente motion (P2) appeared to be related to decreased concentric contraction
of the quadriceps.
If the motor neuron pool is also inhibited during maximal eccentric contraction, as previous studies have suggested, the attenuation of Ia afferents due to the application of prolonged vibration stimulation might not affect or have less of an effect on the recruitment of high threshold motor units as compared with concentric contraction
Every lift consists of a concentric contraction
and an eccentric contraction.
On the other hand, the sEMG amplitude increased for both IDC and DBC protocols from the beginning to the end of concentric contraction
, reaching statistical significance (p <0.
The concentric contraction
would be more efficient in generating that stimulus.
