Chapter 1-3 Flexibility Training Concepts: Active Isolation, Dynamic Stretches, and Programming
Types of Stretching Techniques
General Overview
Flexibility training includes various types of stretches categorized into active and passive stretching.
Active Stretching: Requires clients to actively produce force to apply a stretch.
Passive Stretching: Involves the use of external forces (trainer or tools) to apply a stretch.
Further Classification
Stretching techniques can be classified as:
Static Stretching: Tissue is lengthened and held for a period.
Dynamic Stretching: Involves movement across a full range of motion.
Static Flexibility Techniques
Types of Static Stretches
Active Stretching: Muscle is actively lengthened in a slow, controlled manner and held at terminal range.
Active Assisted Stretching: Builds on static stretch by adding external force from a partner or implement (towel, band).
Requires caution to avoid overstretching.
Effective communication between trainer and client is essential.
Proprioceptive Neuromuscular Facilitation (PNF): Combines active assistance with neural factors for enhanced flexibility.
Often used in rehabilitation settings.
Based on autogenic inhibition via Golgi tendon organs.
Active Isolation Stretching: Similar to PNF, focusing on holding stretches for a shorter time with movement.
Key Points about Static Stretching
Most common technique for improving flexibility.
Should be performed at the end of training sessions to aid muscle relaxation and reduce power output.
Dynamic Flexibility Techniques
Types of Dynamic Stretches
Dynamic Performance Stretches: Utilize exaggerated movements for sport-specific functions, e.g., high knees.
Slow Speed Dynamic Stretches: Performed at a slower pace with isolated movements (e.g., lunges with rotational reach).
Ballistic Stretches: Utilize momentum for maximal range of motion; can be riskier (e.g., swinging limbs, bouncing stretches).
Purpose and Benefits
Dynamic stretches prepare the body for movement and improve range of motion.
Incorporate functional movement patterns into routines.
Basic Programming Guidelines for Flexibility Training
Routine Integration
Flexibility routines can be standalone or integrated into training sessions.
Generally used during warm-ups (dynamic stretching) or cool-downs (static or PNF stretches).
Recommendations for Stretching
Static Stretches:
2 to 4 sets of 15 to 30 second holds for the targeted muscle groups.
Include 10 to 12 stretches for full body improvement at least 2 to 3 times per week.
PNF Stretches:
Follow earlier protocols: 5 to 10 seconds of contraction followed by 6 to 12 seconds of passive hold.
Up to 30-second holds for tolerable discomfort.
Dynamic Stretches:
Aim for 1 to 2 minutes of stretch time per muscle group rather than traditional holds.
Other Techniques
Foam rolling and myofascial release can also be included during warm-ups and cool-downs to address trigger points and muscle tightness.
Important Considerations
All stretches should be performed to tolerable discomfort, avoiding pain.
