Sustained stretching over time can make the connective sheaths that encase muscle — plus tendons, ligaments, fascia, and scar tissue — undergo a semi-permanent change in length.
Detail
With increased stretch over a period of time, the fascial sheaths encasing the muscles may undergo a semi-permanent change in length. These sheaths include the epimysium, endomysium, and perimysium (the connective layers shown in muscle structure; see Structure of Skeletal Muscle). Additional tissues that adapt to the stretch are the tendons, ligaments, fascia, and scar tissue.
This is the second of the three adaptations listed under What Happens When You Stretch. Static stretching, held long enough, is the technique that permits this semi-permanent length change (Static Stretching).
Key facts
- Sustained stretching over time can produce a semi-permanent length change in fascial sheaths.
- Sheaths involved: epimysium, endomysium, perimysium.
- Other adapting tissues: tendons, ligaments, fascia, scar tissue.
Connections
- What Happens When You Stretch — parent concept (adaptation 2 of 3).
- Structure of Skeletal Muscle — defines epimysium, perimysium, endomysium.
- Static Stretching — permits the semi-permanent change in length.
