What Is Flexibility?
• Flexibility: The ROM possible in a joint or group
of joints—highly specific.
• Static flexibility: Holding a stretched position.
• Dynamic flexibility: Moving slowly and
rhythmically through a full ROM—speed highly
specific.
• Ballistic flexibility: Moving through a ROM with
bobbing (not recommended).
• Laxity and hypermobility: Excessive ROM.
Importance of Flexibility
• Back pain—one part suffering . . .
• Sit-and-reach test as predictor?
• Between ages 20 and 70 there is a typical
decrease of 20 to 30% in flexibility.
• Living abundantly?

Factors That Affect
Flexibility
• Bone structure
• Elbows (hinge joint)
• Shoulders (ball-and-socket joint)
• Ligament strength—sprains occur when a
ligament is stretched
• Muscle and tendon elongation
• Joint restriction—by large abdomen
• All created unique

How Much Flexibility Is
Enough?
Stretching
• Questionable value before activity (unless
movements expected to go well beyond normal
ROM)
• Best done following activity—needs to be regular
• Earn flexibility, and abundant life, as the body ages
• Never forget the unique creation of each person.
Assessing Your
Flexibility
• Hamstrings and back: sit-and-reach test
Not helpful
• “Stiff as a board”
• Hypermobility
