Introduction
Quickly assess your knowledge of Physiology of Flexibility & Stretching, and identify gaps in your education. See below for assessments on these subjects:
- Physiology of Flexibility & Stretching
- Stretch-Related Reflexes
- Stretching Issues & Techniques
Purpose
Offer a series of free quizzes for yoga teachers to:
- Provide an effective way to assess knowledge of each of the Teaching Knowledge Standards.
- Make it easy to self-assess privately, on your own time.
- Help teachers who identify educational gaps to bolster their knowledge with accessible and practical lessons.

Physiology of Flexibility & Stretching
Teaching Standard
Understand what limits flexibility (including connective tissue and the nervous system) and gain a deeper understanding of stretching.
Assessment
Vocabulary Mix & Match
ACTIVE STRETCHING |
| |
Stretch done with movement |
DYNAMIC STRETCHING |
| |
Stretch is done with contraction while lengthening (eccentric contraction) |
FACILITATED STRETCHING |
| |
Affects the nervous system in a way that relaxes muscle fibers (Many other definitions included in lesson) |
FLEXIBILITY |
| |
Many non-yoga sources define it as using an outside force such as a partner; most yoga sources likely mean what Ray Long calls Passive Static Stretching, defined as relaxing into the stretch such as in a Restorative Pose |
PASSIVE STRETCHING |
| |
Contracting the muscle in opposition to the targeted stretching muscle |
PROPRIOCEPTIVE NEUROMUSCULAR FACILITATION (PNF) |
| |
Stretch is performed with no outside force and no movement, and is held for some period of time |
RESISTANCE STRETCHING |
| |
One of many ways that stretching is defined; refers to the greatest pulling force that a material can withstand without breaking; “tensile” refers to pulling apart in contrast to “compressive” which refers to pushing together |
STATIC STRETCHING |
| |
Another name for Proprioceptive Neuromuscular Facilitation (PNF) |
STRETCHING |
| |
The ability to move (without pain or restriction) through a joint’s range of motion |
TENSILE LOAD / TENSILE STRENGTH |
| |
A muscle group is passively stretched, then contracts isometrically against resistance while in the stretched position, and is then passively stretched again |
Questions
- Flexibility may be limited by muscles that are shortened, tight or in a contracted state. Name four additional factors that may limit flexibility.
- When anesthetized, what happens to a person’s muscles? What is the significance regarding flexibility?
- What happens when personal ROM limits are reached?
- What are the three states that a muscle may exist in?
- What are the effects of stretching?
- Jules Mitchell defines stretching as a “tensile load.” What does that mean?
- In addition to the basic effects, what are the benefits of stretching?
- What is passive / passive static stretching? Give an example.
- What is active / active static stretching? Give an example.
- What is dynamic stretching?
- What is resistance stretching?
- How are facilitated stretching and PNF related?
- What is PNF?
Stretch-Related Reflexes
Teaching Standard
Become knowledgeable about the Stretch Reflex, the Golgi Tendon Reflex and Reciprocal Inhibition, and explore how to apply this knowledge in teaching.
Assessment
Vocabulary Mix & Match
STRETCH-RELATED REFLEXES |
| |
Another name for the Golgi Tendon Reflex |
SPINAL REFLEXES |
| |
When tension on a tendon exceeds a certain amount, the muscle automatically releases, preventing the tendon from being torn |
STRETCH REFLEX |
| |
Reflexes that bypass the brain, happening unconsciously |
GOLGI TENDON REFLEX |
| |
Messages from proprioceptors cause a muscle to contract; designed to prevent muscle tearing from a forceful action or going beyond normal range |
RECIPROCAL INHIBITION |
| |
Another name for the Stretch Reflex |
CLASP KNIFE REFLEX |
| |
When an agonist muscle contracts, the antagonist relaxes |
INVERSE STRETCH REFLEX |
| |
Spinal reflexes that impact muscle length and tension: the Stretch Reflex, the Golgi Tendon Reflex and Reciprocal Inhibition |
MUSCLE SPINDLE STRETCH RECEPTOR |
| |
Another name for the Golgi Tendon Reflex |
MYOTATIC REFLEX |
| |
Another name for the Stretch Reflex |
SPINAL CORD REFLEX ARC |
| |
Another name for the Stretch Reflex |

Stretching Issues & Techniques
Teaching Standard
Become proficient in identifying and preventing overstretching as well as practices that do and do not improve flexibility.
Assessment
- Not every student needs to increase their range of motion. Expand on the importance of working with students to address their particular needs.
- Very flexible students may need to guard against pursuing “flexibility for its own sake.” How might these students redirect their focus during stretching?
- Name six signs that could indicate overstretching.
- What condition makes students more prone to overstretching?
- Jill Miller has been transparent about the issues resulting from her history of overstretching. What happened from overstretching and what was her diagnosis?
- What are some stretching practices that do NOT improve flexibility?
- Name two safe and effective strategies for improving flexibility.
- What specific stretching techniques may improve flexibility?
- How is it possible that mindfulness contributes to effective stretching?
- Provide three key teachings related to mindfulness during stretching.
- Although doing a vinyasa or short static hold of a pose can warm up the body and make it easier to stretch, why isn’t this enough to improve flexibility?
- Why are long holds necessary for addressing postural tension and making flexibility gains?
- Describe progressive deepening techniques.
- What other expert recommendations — that are often naturally accomplished in a well-rounded asana practice — will contribute to effective stretching?
- In addition to stretching, myofascial release may be a necessary and effective practice. What are some examples of myofascial release techniques?
- Is myofascial release recommended before, during or after a regular practice?
