Presentation Package for Concepts of Physical Fitness 14e Section III: Concept 9 Flexibility and Stretching Exercises Anatomical graphics from: Essentials of Human Anatomy and Physiology McGraw-Hill, 1998 All rights reserved Regular stretching exercises promote flexibility— a component of fitness—that permits freedom of movement, contributes to ease and economy of muscular effort, allows for successful performance in certain activities, and provides less susceptibility to some types of injuries or musculoskeletal problems.
Concepts of Physical Fitness 14e2 Flexibility Activity Flexibility is an important, but often neglected part of an exercise program.Flexibility is an important, but often neglected part of an exercise program. The importance of flexibility for health and well- being becomes more important with age.The importance of flexibility for health and well- being becomes more important with age.
Concepts of Physical Fitness 14e3 Flexibility Fundamentals Not the same as stretching.Not the same as stretching. The range of motion in a joint or joints is used to reflect flexibility at that joint.The range of motion in a joint or joints is used to reflect flexibility at that joint. –ROM= the extent and direction of movement that is possible. –Joint specific Specific vocabulary is used to describe the movement of joints.Specific vocabulary is used to describe the movement of joints. –Flexion/extension, abduction/adduction, internal and external rotation, etc. (see next slide)

Concepts of Physical Fitness 14e5 Flexibility Fundamentals continued The unique nature of the different joints causes some to allow for greater mobility than others.The unique nature of the different joints causes some to allow for greater mobility than others. –Ball-and-socket joint –Hinge joint ROM at a joint depends on how it is being assessedROM at a joint depends on how it is being assessed –Static = without movement –Dynamic = active functional activity
Concepts of Physical Fitness 14e6 Factors Influencing Flexibility AnatomyAnatomy –Long “muscle-tendon units” (MTUs) –Properties of connective tissue and muscle –Type of joint GenderGender –Females more flexible Possibly related to:Possibly related to: –bone structure (e.g., wider hips) –hormonal influences –physical activity choices (e.g., dance, gymnastics, swimming) that require good flexibility

Concepts of Physical Fitness 14e10 Flexibility & Back Pain Short and tight muscles cause poor posture which leads to back pain.Short and tight muscles cause poor posture which leads to back pain.
Concepts of Physical Fitness 14e11 Flexibility & Back Pain n Long and strong muscles keep the body in good alignment and reduce risk of back pain.

Concepts of Physical Fitness 14e20 How Much Flexibility is Enough? How Much Stretching is Enough?
Concepts of Physical Fitness 14e21 How much is enough? Stretching exercises should be done regularly to achieve optimal benefits.Stretching exercises should be done regularly to achieve optimal benefits. For flexibility to be increased, you must stretch and hold muscles beyond normal length for an adequate amount of time. (see the stretch reflex on the next slide)For flexibility to be increased, you must stretch and hold muscles beyond normal length for an adequate amount of time. (see the stretch reflex on the next slide) Performing warm-up exercises is not the same as doing a stretching workout for flexibility development.Performing warm-up exercises is not the same as doing a stretching workout for flexibility development. The best time for stretching is when the muscles are warm.The best time for stretching is when the muscles are warm.
Concepts of Physical Fitness 14e22 Stretch Reflex Maintaining stretch for 10- 30 seconds will allow the stretch reflex to subside and permit gains.
