Key result
Eccentric exercise of the elbow flexors performed with free weights induced muscle damage of similar magnitude to isokinetic dynamometer exercise, with no significant difference in MVIC peak torque between groups.
Why the study?
Eccentric exercise-induced muscle damage of elbow flexors is commonly studied using isokinetic dynamometers, but it is possible the magnitude differs for exercises performed with free weights.
Does eccentric exercise performed with free weight compared to an isokinetic dynamometer induce a different magnitude of muscle damage in well-trained men?

Free-weight eccentric elbow flexor exercise produces EIMD comparable to isokinetic dynamometry; leaves open whether findings generalize beyond small trained cohorts.

p-value: p=0.102
Eccentric exercise of the elbow flexors performed with free weights induces muscle damage with similar magnitude and duration as an isokinetic dynamometer in well-trained men.
Halmenschlager et al. (2022) conducted an RCT in Exercise-induced muscle damage (n=17). Free weight eccentric exercise vs. Isokinetic dynamometer eccentric exercise was evaluated on Maximal voluntary isometric contraction (MVIC) peak torque (p=0.102). Eccentric exercise of the elbow flexors performed with free weights induced muscle damage of similar magnitude to isokinetic dynamometer exercise, with no significant difference in MVIC peak torque between groups.
