The KinCom can measure both concentric and eccentric contractions as well as isometric contractions and a special type of isotonic contraction called active assist.
A slow eccentric contraction will allow the muscle to safely enter its pre-stretch which is a slight reversal in movement just prior to muscle contraction.
The especially high hamstrings responsiveness to the damaging effects of an exercise bout has already been reported following voluntary eccentric contractions (Croisier at al.

Since they usually land from high places, they are accustomed to a high intensity of eccentric contraction on their quadriceps.
In one small study, 18 volunteers were randomly assigned to a massage or control group; DOMS was induced with six sets of eccentric contractions of the right hamstring.
In contrast, Rodenburg and colleagues (1994) reported that an intervention involving warm-up (15 minutes of arm cycling), stretching and massage produced a statistically significant reduction in one of two measures of muscle soreness (by ~1 point on a 6-point scale at 48 hours) following an exercise protocol that involved intense eccentric contractions of the elbow flexor muscles.

1) Eccentric contractions were produced on anesthetized mice by using electrodes to contract the hind legs while at the same time moving the muscle into a stretched position.
More importantly, during the static stretch the muscles are completely relaxed, whereas in running the muscles perform very dynamically in both concentric and eccentric contractions.
