Summary
Delayed onset muscle soreness (DOMS) in knee extensors alters running biomechanics, reducing sagittal plane knee moments and ankle power. However, DOMS does not impact frontal or transverse plane movements during running.
Area of Science:
- Biomechanics
- Exercise Physiology
- Sports Medicine
Background:
- Delayed onset muscle soreness (DOMS) is common in runners, particularly affecting knee extensors.
- Previous research indicates DOMS alters sagittal plane knee joint biomechanics.
- The impact of DOMS on lower limb biomechanics in other planes of motion remains unclear.
Purpose of the Study:
- To investigate the effects of knee extensor DOMS on three-dimensional (3D) lower limb biomechanics during running.
Main Methods:
- Thirty-three healthy males underwent an eccentric knee extensor damaging protocol to induce DOMS.
- Running biomechanics were assessed at a consistent speed (3.35 m/s) before exercise (baseline) and 24 and 48 hours post-exercise.
- Three-dimensional motion analysis captured lower limb joint kinematics and kinetics.
Main Results:
- Knee flexion range of motion (ROM) was reduced at 48 hours post-DOMS.
- Peak knee extensor moment decreased at both 24 and 48 hours.
- Frontal and transverse plane biomechanics remained unaffected by DOMS.
- Peak positive ankle and knee joint powers, and peak negative knee joint power were reduced post-exercise.
Conclusions:
- Knee extensor DOMS significantly affects sagittal plane knee joint kinetics.
- DOMS leads to reduced sagittal power production at the ankle joint during running.
- Lower limb biomechanics in the frontal and transverse planes are not influenced by knee extensor DOMS.
