What is the purpose of the Side Bridge:Extension ratio in McGill's test battery?

  1. Assess upper body strength

  2. Evaluate core stability

  3. Measure arm endurance

  4. Determine leg strength

The correct answer is: Evaluate core stability

The purpose of the Side Bridge:Extension ratio in McGill's test battery is to evaluate core stability. This test focuses on the endurance and strength of the core muscles, which play a crucial role in maintaining stability during various physical activities. The Side Bridge specifically targets the lateral stabilizers of the trunk, while the Extension test assesses the muscles of the back. By comparing the performance in these two exercises, trainers can gain insights into the balance and endurance of the core musculature, which is fundamental for overall functional movement and injury prevention. Strong core stability is essential for athletes and individuals engaging in regular physical activity, as it supports proper mechanics and posture while performing exercises or daily tasks.
