Study Notes

Davis's Law

Soft tissue adapts and regenerates based on stress and usage patterns.

Key Definitions

Relative Flexibility: Tendency of the body to adopt the path of least resistance during movement, often leading to improper movement patterns.
Muscle Imbalance: Occurs when muscle length around a joint is improper, leading to incorrect movement or posture.
Altered Reciprocal Inhibition: Inhibition of a muscle due to tightness in its antagonist, affecting performance.
Self Myofascial Release (SMR): Technique that uses bodyweight or applied pressure to release muscle adhesions.
Synergistic Dominance: When a synergist muscle compensates for a weak prime mover, e.g., hamstrings compensating for gluteus maximus during hip extension.

Reciprocal Inhibition

Active contraction of an antagonist muscle promotes relaxation and further stretching of the targeted muscle.
Active-Isolated Stretching is a technique that employs reciprocal inhibition for effective stretching.

Muscle Spindles vs. Golgi Tendon Organ

Muscle Spindles: Located within muscles, sensitive to changes in muscle length.
Golgi Tendon Organ: Located in tendons, sensitive to tension levels in the muscle.

Flexibility Recommendations

Corrective Flexibility: Recommended for the stabilization level, combining SMR and static stretching techniques.
SMR is effective for releasing trigger points or knots in muscle tissue.

Cumulative Injury Cycle

Stages: Tissue Trauma, Inflammation, Muscle Spasm, Adhesions, Altered Neuromuscular Control, Muscle Imbalance.
Addressing the cycle through SMR and static stretching can restore neuromuscular control and reduce imbalances.

Integrated Flexibility Continuum

Corrective Flexibility: First phase, utilizes autogenic inhibition, SMR (30 seconds) and static stretching (30-60 seconds).
Active Flexibility: Second phase, utilizes reciprocal inhibition; consists of SMR and active-isolated stretching (1-2 seconds, repeated 5-10 times).
Dynamic Flexibility: Third phase involves SMR and dynamic stretching; focuses on full range of motion, performing 10 repetitions without holding the stretch.

Important Techniques

Autogenic Inhibition: Achieved through foam rolling, helps decrease muscle spindle activation by activating the Golgi tendon organ.
Knowledge of performing all stretches is essential for effectively guiding clients and understanding the targeted areas during each stretch.
