Static stretching is one example of how muscle tension signals a GTO response. So, when you hold a low-force stretch for more than seven seconds, the increase in muscle tension activates the GTO, which temporarily inhibits muscle spindle activity (thus reducing tension in the muscle), and allows for further stretching.
How does the muscle spindle work when stretching?
- Stretching muscles to generate force. Loading the muscle spindle: When activated the muscle spindle causes the muscle being stretched to generate tension to resist the stretch, so by stretching a muscle immediately prior to a contraction you effectively prime the muscle to create more force for that contraction.

Which of the following choices is the most appropriate form of stretching to use during a warm up prior to athletic activities?
Dynamic stretches should be used as part of your warm-up routine before any athletic event, whether competitive or not. A complete athletic warm-up should incorporate about 5 to 10 minutes of low- to moderate-intensity swimming, jogging or cycling, followed by dynamic stretching.
When stimulated during PNF stretching GTO allows the relaxation of the?
PNF stretching allows for relaxation of the stretched muscle by stimulating Explanation: When golgi tendon receptors are stimulated, they cause inhibition of the muscle being stretched, leading to greater relaxation of the muscle. Which of the following sports likely requires more stretching?
What do muscle spindles do in PNF?
The muscle spindle is a long thin nerve receptor found within the muscle. Information from this receptor transmits information to the spinal cord regarding muscle length and the speed of lengthening.
How do muscle spindles work?
Functionally, muscle spindles are stretch detectors, and sense how much and how fast a muscle is lengthened or shortened. Accordingly, when a muscle is stretched, this change in length is transmitted to the spindles and their intrafusal fibers which are subsequently similarly stretched.
Which stretching method is not recommended?
Ballistic stretching is generally not recommended for everyday people who want to stay in shape or improve flexibility because there is a risk of straining or pulling a muscle. Static stretching stretches muscles more gently without risk of pulling them.
Does stretching improve flexibility?
However, research has shown that stretching can help improve flexibility, and, consequently, the range of motion of your joints. Better flexibility may: Improve your performance in physical activities. Decrease your risk of injuries.
What are the 3 types of PNF stretching?
The three main PNF techniques are hold-relax, contract-relax, and hold-relax with agonist contraction. If you’re unfamiliar with how these partner stretching techniques work, it’s best to consult a physical therapist or personal trainer.
What are examples of PNF stretching?
PNF Stretching An example would be biceps and triceps in the arm and hamstrings and quadriceps in the leg. You should only do this form of stretching with the help of a qualified fitness specialist.
Which type of stretching causes the muscle to contract rather than relax?
Isometric stretching is a type of static stretching (meaning it does not use motion) which involves the resistance of muscle groups through isometric contractions (tensing) of the stretched muscles (see section Types of Muscle Contractions).
What is P and F stretching?
Proprioceptive Neuromuscular Facilitation (PNF) is an advanced form of flexibility training, which involves both the stretching and contracting of the muscle group being targeted. PNF stretching is one of the most effective forms of stretching for improving flexibility and increasing range of motion.
What is stretch reflex?
The stretch reflex or myotatic reflex refers to the contraction of a muscle in response to its passive stretching by increasing its contractility as long as the stretch is within physiological limits.
What will stretching of muscle spindles cause quizlet?
Ia- They are very sensitive to changes in muscle length, so stretch would cause those nerves to fire.
What is the muscle spindle stretch receptor?
Muscle spindles are stretch receptors that signal the length and changes in length of muscles. They lie within an independent capsule, parallel to the main muscle. They are therefore stretched when the muscle lengthens but shorten when the muscle contracts.
What is muscle spindle stretch reflex?
When muscles lengthen, the spindles are stretched. This stretch activates the muscle spindle which in turn sends an impulse to the spinal cord. This impulse results in the activation of more motor neurons at spinal level that send an impulse back to the muscle.
