Study Notes
Neuromuscular System
- Neuromuscular efficiency refers to the ability of the neuromuscular system to enable agonists, antagonists, and stabilizers to work together, stabilizing the kinetic chain across all three planes of motion.
Muscle Imbalances
- Postural distortion patterns denote predictable muscle imbalance configurations.
- Relative flexibility is the body's tendency to adopt the path of least resistance in functional movements, influenced by tight muscles and connective tissue.
Causes of Muscle Imbalances
- Muscle imbalances can arise from altered reciprocal inhibition, synergistic dominance, and arthrokinematic dysfunction.
Muscle Function
- Reciprocal inhibition involves simultaneous muscle relaxation of one while another contracts, facilitating movement (e.g., bicep curl where biceps contract and triceps relax).
- Altered reciprocal inhibition results from tight agonist muscles inhibiting their antagonists, disrupting force relationships and movement patterns.
Synergistic Dominance
- This occurs when synergistic muscles compensate for inhibited prime movers, leading to dysfunctional movement mechanics.
Arthrokinematic Dysfunction
- Refers to abnormal joint forces causing distorted muscular activity and impaired neuromuscular communication.
Flexibility Dysfunction Assessment
- To address flexibility dysfunction, prioritize stretching overactive muscles.
Inhibition Mechanisms
- Autogenic inhibition is when tension-sensing impulses exceed contraction impulses, leading to muscle relaxation.
Movement Patterns
- Pattern overload happens when repetitive motion creates abnormal stresses on the body.
Davis's Law
- States that soft tissue adapts along stress lines; injuries can lead to inelastic collagen formation that restricts extensibility.
Flexibility Training Phases
- Three phases include corrective, active, and functional flexibility training.
Corrective Flexibility
- Applied during the stabilization level of the OPT model, utilizing self-myofascial release and static stretching techniques.
Active Flexibility
- Employed during the strength level of the OPT model (phases 2, 3, 4) and includes self-myofascial release and active isolated stretching.
Active-Isolated Stretching Technique
- Utilizes agonists and synergists for dynamic movement through a range of motion while simultaneously stretching the antagonist.
Functional Flexibility
- Part of the power phase of the OPT model, using self-myofascial release and dynamic stretching techniques.
Dynamic Stretching
- Requires integrated, multiplanar movements executed with optimal neuromuscular control and full range of motion.
Self-Myofascial Release Duration
- Hold stretches on tender spots for 30 seconds when performing self-myofascial release.
Self-Myofascial Release Examples
- Notable techniques include SMR for the gastrocnemius/soleus, adductors, and latissimus dorsi.
Static Stretching for Corrective Flexibility
- Focus on static stretches like gastrocnemius/soleus stretch, adductor stretch, and latissimus dorsi stretch to enhance flexibility.
