In order to produce maximum torque for an isokinetic concentric contraction, should the speed of the motion be fast or slow? For an isokinetic eccentric contraction?

What will be an ideal response?

ANS: Isokinetic contractions are most commonly concentric but may also be produced eccentrically. A
slower concentric contraction will always produce greater tension than a faster one using the same
number of motor units. The slowest isokinetic contraction (therefore, the one producing the
greatest tension) is one that does not produce movement (that is, an isometric contractionâ€"0 °/sec).
In an eccentric isokinetic contraction, a faster speed produces more tension than a slower
contraction using the same number of motor units. Consequently, peak isokinetic eccentric torque
will be greater for a given muscle with faster machine settings, as long as the person can maintain
the preset speed.
