What is the long-term lengthening of connective tissues called?

plastic elongation

What determines flexibility?

genetics

The modified hurdler stretch targets which muscles?

hamstring muscles

What structures absorb and disperse stress on the spine?

intervertebral disc

What is the most common site of back pain?

lumbar

Upon what does static flexibility depend?

- The ability to tolerate stretched muscles - the structure of your joints - the elasticity of muscles

What muscles are included in the core muscles?

- abdomen - pelvic floor - sides of the trunk - back - buttocks - hip - pelvis

What is most likely to cause back pain?

- heavy lifting - muscle weakness - poor posture

Name a benefit that comes with flexibility?

- joint health - prevent arthritis - increases balance & stability - prevention of lower back pain & injuries - improved posture - relaxation - reduces muscle cramps

What is one benefit of stretching?

- joint health - prevent arthritis - increases balance & stability - prevention of lower back pain & injuries - improved posture - relaxation - reduces muscle cramps

What is one likely outcome of good flexibility?

- joint health - prevent arthritis - increases balance & stability - prevention of lower back pain & injuries - improved posture - relaxation - reduces muscle cramps

What activity best demonstrates dynamic flexibility?

- pitching a ball - swinging a golf club

Why are ballistic stretches considered dangerous?

- they heighten activities that cause muscle to contract by triggering strong responses from the nerves can cause a reflux muscle contraction that make it harder to stretch - strains muscles

According to the American College of Sports Medicine (ACSM), how many days a week should one perform stretching exercises?

2 - 3 days a week

How many repetitions of a stretch should you do during a stressing session?

2 to 4

What are the yellow fibers that make connective tissue flexible?

Elastin

Which is a proprioceptor?

Nerves that send information about the muscular and skeletal system to the nervous system

What type of stretching features contracting a muscle prior to stretching?

PNF stretching

What is a disadvantage of active stretching?

a person may not be able to produce enough stress to increase flexibility using only the contraction of opposing muscle groups

What is considered one of the safest stretching techniques?

active static stretching

Which stretching technique is most commonly associated with injury?

ballistic stretching

What are stabilization exercises particularly good for?

building core stiffness and strength

What are the two principle types of connective tissue in a muscle?

collagen and elastin

Which is an essential component of safe passive stretching?

communicating between you and your partner

Full range of motion spine exercises performed soon after waking can lead to injury because...

discs are full of fluid when waking due to no movement for a long period of time

What is the focus of dynamic stretching?

focuses on movements that work through the range of motion required for the sport - daily movements

What are joint capsules?

semi elastic structures that give joints strength/stability, but limit movement

Which test is used to determine the flexibility of muscles in the hamstrings?

sit and reach

Which stretching technique do experts recommend for general fitness?

static stretching
