flexibility and performance improves performance capacity: only if flexibility is generated by
longer muscles
1. reach and runway from adequate task flexibility
2. muscle contractile velocity and power output - longer muscles and faster
3. may optimize resting length for a task (force-length relationship)
laxity and health not good for health or performance
- unless in cirque du soleil
stability and health prevents slips and falls
prevents joint injuries
stability and performance postural stability improve performance
can you improve flexibility depends on age
- easier in children
depends what is constraining motion
- impingement
-tension in a link
, impingement a movement of a joint is constrained by impingement or compression of
articulations
- pushing bone against bone frequently, makes the bone grow bigger/thicker (embossment)
causes damage
tension in a link, constraining motion - then you may be able to improve flexibility (stretch
to grow longer)
- hard to do in adults, but children can stretch to make longer
stretching in adults makes it more tolerant to being stretched and improve RoM
does someone need to improve flexibility can they complete daily activities, sports and rec,
occupational activities
streching lengthening something by tension
- every motion of the human body stretches an element of the body (swinging)
variables in stretching what constrains of motion are being stretched/ lengthened
what is the intensity
- how is the force generated (passive/active)
