Comparison of Lower Limb COP and Muscle Activation During Single-Leg Deadlift Using Elastic and Inelastic Barbells
In Brief
A clinical study evaluating Elastic Barbell and Inelastic Barbell for Neuromuscular Control and 2 related conditions. Completed, enrolled 27 participants across 1 site.
Detailed Summary
This study aims to investigate the effects of barbell type (elastic vs. inelastic) and lifting speed on lower limb balance and muscle activation during the Single-Leg Deadlift (SLDL) exercise. Using a randomized crossover design, healthy adults performed SLDL at three different movement speeds while center of pressure (COP) and electromyographic (EMG) responses were measured. The study seeks to determine whether elastic barbells, which create top-down perturbations, enhance neuromuscular control and postural stability more effectively than traditional inelastic barbells.
Study Details
Timeline
Interventions
A flexible plastic barbell that creates top-down perturbations during movement. Participants perform single-leg deadlifts using this elastic bar at three different speeds: normal (2 sec), fast (1 sec), and power (as fast as possible). The bar is loaded to 30% of the participant's estimated 1RM.
A standard rigid steel barbell with no elasticity. Participants perform single-leg deadlifts using this barbell under the same speed conditions and loading parameters as the elastic barbell.
