Objective: To investigate the pattern of muscle activation of the individual hip adductor muscles using a standardised simulated unilateral weight-bearing task.
Design: A repeated measures design.
Setting: Laboratory.
Participants: 20 healthy individuals (11 females, 9 males) participated in the study. Age ranged from 20 to 25 years.
Main outcome measurements: Surface electromyography recordings from adductor magnus and adductor longus muscles were taken at levels representing 10–50% of body weight during a simulated weight-bearing task. Electromyography (EMG) data were normalised to maximal voluntary isometric contraction.
Results: The adductor magnus was recruited at significantly higher levels than the adductor longus muscle during a simulated weight-bearing task performed across 10–50% of body weight (p < 0.01).
Conclusions: Adductor magnus and adductor longus muscles are recruited to different extents during a simulated weight-bearing task. This information should be considered when selecting exercises for management and prevention of groin strains. Closed chain exercises with weight-bearing through the lower limb are more likely to recruit the adductor magnus muscle over the adductor longus muscle.
