CrossFit Level 2: CrossFit Level 2 Exam Study Guide: Questions & Answers

Midline (Ans- The relationship of the spine and pelvis during functional movement Midline Stabilization (Ans- Athlete's capacity to prevent movement from a neutral spine position Midline stabilization is synonymous with (Ans- Core strength Midline stabilization determines if an athlete can (Ans- Maintain the natural s-curve of the spine to the pelvis when dynamic and/or loaded Stabilization of spine is accomplished by engaging the (AnsAbdominals Internal and external obliques Erector spinaeTorso as a rigid, integrated structure (Ans- Enables transmission of force between the appendages Ideal midline orientation (Ans- Vertical; this is optimal muscular skeletal alignment for force distribution When midline stabilization is lost (Ans- Shear force experienced by the spine increases, attempting to push one vertebra past another Deviations from neutral (Ans- Occur in flexion (forward) and extension (backwards) Safest spinal positioning (Ans- Midline stabilization in a neutral position More risky spinal positioning (Ans- Non-neutral spine in a static position Most risky spinal positioning (Ans- Loss of neutral spine during movementMost common injury from loss of midline stabilization (Ans- Lumbar spine flexes under load Core to Extremity Movement (Ans- A sequence of muscular contraction that begins with the large force producing, low velocity muscles of the core and hips and ends with the small force producing, high velocity muscles of the extremities. Core to extremity movement begins with (Ans- Establishing midline stabilization for effective force transfer; creating a base Core to extremity movement maximizes performance because: (Ans- It tasks the largest musculature to generate force first, allowing the greatest force to develop Violating core to extremity movement (Ans- Puts smaller muscle groups, tendons and ligaments at a higher likelihood of resulting in injury such as tearing
