Little research has been done evaluating the effects of muscle soreness on a lifting task.
To examine the effects of delayed-onset muscle soreness (DOMS) in the thigh musculature on kinematic and kinetic variables associated with the squat-lifting technique.
Pretest–posttest repeated measures, with treatment as the independent variable (DOMS and no DOMS of the thigh musculature).
Twenty healthy college students.
Subjects were videotaped lifting a 157-N crate before and after DOMS inducement.
A 2-dimensional sagittal-plane video analysis was used to calculate 7 kinematic and kinetic variables.
DOMS had no effect on L5/S1 torque and shear or compression, hip torque and range of motion, or knee torque and range of motion during lifting.
DOMS does not appear to alter kinematic and kinetic variables associated with the squat-lifting technique.
