Study Notes

Stretching Techniques and Guidelines for a Safe and Successful Program

The Contract-Relax-Contract (CRC) stretching technique involves an initial isometric muscle action, relaxation, and then a concentric muscle action of the opposing muscle, followed by stretching the initial muscle.
An example of CRC is the hamstring muscles stretch, involving an isometric action, relaxation, concentric action of the quadriceps, and partner-assisted stretching.
Passive stretching involves an external force or resistance to move the joint, while active stretching is achieved by the contraction of the opposing muscle.
Passive stretching carries a higher risk of injury and requires caution to prevent joint movement beyond its normal range.
Active stretching is considered safer and more suitable for individuals beginning flexibility training.
Guidelines for creating a safe and successful stretching program include static stretching, holding stretches for 10-30 seconds, and increasing intensity gradually.
Progress in flexibility can be judged by observing body position during stretching or repeating assessment tests, with noticeable improvements in 2-3 weeks and significant improvements in about 2 months.
Excessive flexibility should be avoided as it can lead to joint instability.
The FITT-VP principle for a flexibility program includes specific stretching exercises for different muscle groups, such as head turns & tilts for neck muscles and sternocleidomastoid, and towel stretch for chest, shoulders, and rear upper arms.
Other stretching exercises include across-the-body & overhead stretches, upper-back stretch, lateral stretch, step stretch, side lunge, inner thigh stretch, hip & trunk stretch, and modified hurdler stretch.
Each stretching exercise targets specific areas and muscles, such as the side lunge targeting the inner thigh, hip, and calf muscles.
The FITT-VP principle provides a comprehensive framework for planning and implementing a flexibility program, with a focus on specific stretching exercises targeting various muscle groups.

Nervous System Regulation and Flexibility

Alpha motor neuron is a nerve cell in the spinal cord that sends signals to muscle fibers, making them contract.
Afferent nerve fibers carry signals from the periphery to the central nervous system, while efferent nerve fibers carry signals from the central nervous system to the periphery.
Agonist muscles contract while their antagonist muscles relax at the same time.
Muscle spindles are composed of specialized muscle fibers that provide information about the length of skeletal muscles and control their length.
The stretch reflex relieves muscle stretching and prevents overstretching.
When a muscle is stretched, muscle spindles send an electrical signal to the spinal cord through afferent nerve fibers, triggering muscle contraction through the alpha motor neuron.
Golgi tendon organs are located in series with skeletal muscle fibers and provide information about muscle tension.
The inverse stretch reflex initiated by Golgi tendon organs protects muscles from excessive tension and results in reflexive muscle relaxation.
Muscle spindles and Golgi tendon organs have different locations, sense and monitor different variables, and activate different reflexes.
Good flexibility provides benefits for the entire musculoskeletal system.
Rapid stretching of the biceps brachii muscle results in concentric muscle action in the biceps brachii and relaxation in the triceps brachii muscle.
Both muscle spindles and Golgi tendon organs play crucial roles in regulating muscle function and flexibility.
