Hip abduction strength training in the clinical setting: with or without external loading?

Area of Science:

• Exercise Physiology
• Rehabilitation Science
• Biomechanics

Background:

• Side-lying hip abduction is a common rehabilitation exercise.
• It is frequently performed without external resistance.
• Its effectiveness with varying loads requires investigation.

Purpose of the Study:

• To compare the effects of 6 weeks of side-lying hip abduction training with and without external loading.
• To assess the impact on hip abduction strength in healthy individuals.

Main Methods:

• A randomized controlled trial involving 31 healthy, active participants.
• Two groups: hip abduction training with external load (10-repetition maximum) and without external load (bodyweight only).
• Hip abduction strength (isometric and eccentric) measured pre- and post-intervention.

Main Results:

• Both training groups showed significant increases in isometric and eccentric hip abduction strength.
• Training with external loading increased strength by 12% (isometric) and 17% (eccentric).
• Training without external loading increased strength by 11% (isometric) and 23% (eccentric).
• No significant differences in strength gains were observed between the groups.

Conclusions:

• Six weeks of side-lying hip abduction training enhances both isometric and eccentric hip abduction strength.
• External loading does not produce superior strength gains compared to bodyweight resistance alone.
• The exercise is effective for improving hip abduction strength regardless of external load.
