THEORETICAL - PRACTICAL
The combination of poor mobility and excessive or poor stability is the source of many common injuries during physical activity.
| KEY FACTORS AFFECTING RANGE OF MOTION OF THE JOINTS |
| • Immobility - hypotony - sedentary lifestyle.
• Musculoskeletal lesions.
• Chronic musculoskeletal disorders.
• Shortened muscles and tendons.
• Intra articular injuries.
• Intra articular dysfunction.
• Degeneration of articular cartilage.
• Loosen ligaments and articular capsule.
• Quantitatively excessive adjacent fat tissue.
• Formed scar tissue on skin. |
• Hereditary-genetic factors.
• Age.
• Gender.
• Body type.
• Poor posture.
• Excessively increased muscle mass.
• Badly designed exercise programs-excessive sports activity.
• Low level of fitness.
• Environment temperature, warm-up. |
| RESTRICTIVE STRETCHING FACTORS (as form of exercise) |
| • Muscle tissue elasticity.
• Elasticity of connective tissue.
• Excessive muscle mass.
• High muscle tension.
• Reduced coordination.
• Reduced muscle strength.
• Myotatic reflex (stretch reflex).
• Golgi tendon organs.
• Type C-motor neurons.[1]
• Mechanoreceptors–Muscular spindle.
• Muscle synthesis and composition.
• Muscle imbalances.
• IInadequate muscle control |
• Muscle aging - deterioration of the body.
• Anatomical deformities.
• Structural bone constraints.
• Poor connective tissue quality.
• Poor skin quality.
• Muscle pain.
• Local spasm.
• Fatigue-local muscle fatigue.
• Shortening.
• Low body temperature.
• Inadequate relation.
• Lack of concentration. |
[1] C- or gamma motor neurons: is one of the 3 main types of neurons (sensory, motorkinetic and medial). They form synapses with muscle fibers, transmitting information from the central nervous system that converts them into muscle activity. Reducing their activity reduces muscle tension, while stimulating them results in the contraction of the whole muscle.
