Slide1Chapter SixFlexibility The rubber band theory applies to each of us; we will be no good until stretched.

Slide2Objectivesz How is joint movement limited? z Why is flexibility important? z What is the difference between static stretching and dynamic stretching? z How may the training principles be applied to improve flexibility?

Slide3Objectivesz What safety precautions should be taken when you are engaging in flexibility exercises?  How is flexibility evaluated?

Slide4Chapter 6 Valuez Flexibility is an essential fitness component in both your functional life, as well as when you engage in physical activity. z It is important that you stretch to increase the length of both your muscles and tendons.  The more range of motion you have, the more your joints can move without injury.  Stretching will not only help reduce the chance of injury, minimize muscle soreness, stimulate blood flow, it is also a great stress reliever.

Slide5Vocabularypoint at which 2 bones come together strong, fibrous tissue which attaches one bone to another meaty tissue surrounding bones soft tissues that anchor muscles to bones slowly moving a muscle to its stretching point and holding the position for 15 seconds stretching done in continuous, slow, and controlled manner joint — ligament — muscle — tendon — static stretching — dynamic   stretching —

Slide6Vocabularystretching that involves bobbing, bouncing or jerky movements which use the body's momentum form of stretching in which a partner pushes the body beyond the initial limit isostatic stretching — ballistic stretching —

Slide7Evaluate Goals

Slide8What Is Flexibility?z The ability to move body joints through a full range of motion.

Slide9Joints of the Human Bodyz Point at which 2 bones come together z Types y Pivot y Gliding y Hinge y Ball and socket Vocabulary

Slide10Joints of the Human Body

Slide11Joint Movementz Direction is limited by bone structure and can’t be modified z Range of motion is limited by soft tissue and is modifiable through flexibility exercises Objective 1 of 2

Slide12What Limits Flexibility?z Ligament  — strong fibrous tissue that attaches one bone to another z Muscle  — meaty tissue surrounding bones z Tendon  —  anchors muscle to bone Vocabulary Objective 2 of 2

Slide13Why Is Flexibility Important?z Needed in daily living z Reduces chance of injury z Increases capacity of joint to move z Prevents muscles from shortening z Helps relieve muscle soreness Objective 1 of 2

Slide14Why Is Flexibility Important?z Helps reduce chance of developing low back pain z Helps relax muscle tightness from injury, fatigue, and emotional tension Objective 2 of 2

Slide15Types of Stretchingz Static  — slowly move muscle to stretching point z Dynamic  — continuous, slow and controlled z Ballistic  — bouncing, jerky movement using body’s momentum z Isostatic  — use a partner to stretch beyond your limit Vocabulary Objective

Slide16F.I.T. Applied to Flexibilityz Increase overload by increasing: y F y F requency - number of sessions per day or week y I y I ntensity - distance the muscle is stretched y T y T ime - length of time the position is held, or number of repetitions and sets Objective 1 of 3

Slide17Principle of Progressionz Gradually increase overload by increasing frequency, intensity or time of the exercise Objective 2 of 3

Slide18Principle of Specificityz Stretching exercises will improve flexibility only in joints exercised z Flexibility is specific to each:    1.  Individual    2.  Joint    3.  Sport Objective 3 of 3

Slide19Flexibility Safety Precautions3 Unsafe flexibility exercises 3 Avoid ballistic stretching 3 Don’t use a partner to stretch 3 Start at your appropriate level and progress slowly 3 Stretch by what feels comfortable to you — don’t follow others 3 Combine cardiovascular, muscular strength and endurance exercises to prevent imbalance. Objective

Slide20Flexibility Assessmentz Before beginning testing: 3 Always warm up 3 Avoid ballistic stretching 3 Move in a slow, controlled way Objective

Slide21Flexibility Assessmentz Tests y Sit-and-reach y Shoulder lift y Broomstick dynamic flexibility Vocabulary Objective

Slide22FlexibilityMinimum principles of training guidelines z F z F requency - at least 3 times per week z I z I ntensity - stretch slowly until mild tension is felt z T z T ime - static:  hold stretch for 15 to 30 sec

Slide23Setting Flexibility Goals                                                   Less              close              exceeds Difference between                   <10cm      >1 to 10 cm      at or above Test score & health standard                                              standard Recommended range               5 to 15cm     1 to 4 cm        0 to 2 cm

Slide24Flexibility Exercisesz Upper body and torso z Neck z Triceps z Chest and biceps z Shoulder z 3-prong support side stretch

Slide27Record Progress toward Goal

Slide28Summaryz Flexibility is the ability to move body joints through a full range of motion z The direction of joint movement is limited by the way it is structured z Four types of stretching z Flexibility is limited by soft tissue which includes ligaments, muscles, and tendons
