Comparing the use of a barbell or a barbell plus chains for the snatch lift, using 75 % or 80 % of 1RM with 5 % of chains replacing the same weight of barbell, Coker et al. (2006) found that there was no difference between conditions in relation to maximum vertical displacement of the bar, maximum bar velocity, RFD, and vertical GRF for the first pull, unweighting, and second pull phases of the snatch lift.

Exploring bar velocities in elite female Olympic weightlifters in competition, Garhammer (1991) found that peak barbell velocity ranged between 1.5 — 2.2 m / s, and Garhammer (1985) reported similar values of 1.5 — 2.1 m / s in male gold medalists at the 1984 Olympic games, indicating that there is little difference between genders.

Eccentric - specific gains produced by neural mechanisms might not transfer well to COD ability, because of differences between the strength training exercise and the COD maneuver in terms of both movement pattern, and contraction velocity.

Even so, the adaptations that produce eccentric - specific strength after eccentric training do not appear to be strongly velocity - specific (Alt et al. 2017), and there are indications that athletic populations display smaller differences between maximal involuntary and voluntary eccentric force, even in unfamiliar movements (Amiridis et al. 1996).

This probably causes differences in velocity - specific gains in strength between the two external load types.

However, because strength is velocity - specific, not everyone has an optimal FV profile, and the difference between the optimal and the actual FV profile can be expressed by the FV imbalance.

The difference between the optimal and the actual force - velocity profile can be expressed by the force - velocity imbalance.

However, they found no difference in peak bar velocity between the groups.

When different studies use the same angular velocity for measurement, these can be compared to one another, so long as differences between the populations tested are acknowledged, and so long as the dynamometer used is the same in both cases, as differences have been observed between brands (Francis & Hoobler, 1987; Thompson et al. 1989; Gross et al. 1991).
