Chapter Six Flexibility
The rubber band theory applies to each of us; we will be no good until stretched.

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

Chapter 6 Value Flexibility is an essential fitness component in both your functional life, as well as when you engage in physical activity. 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.
5
Vocabulary joint— point 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 ligament— muscle— tendon— static stretching— dynamic stretching—
6
Vocabulary ballistic stretching—
stretching 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—
7
What Is Flexibility? The ability to move body joints through a full range of motion.
8
Joints of the Human Body
Point at which 2 bones come together Types Pivot Gliding Hinge Ball and socket Vocabulary
9
Joints of the Human Body
10
Joint Movement Range of Motion is the intended degree of movement of a joint Direction is limited by bone structure and can’t be modified Range of motion is limited by soft tissue and is modifiable through flexibility exercises Objective 1 of 2
11
What Limits Flexibility?
Ligament — strong fibrous tissue that attaches one bone to another Muscle — meaty tissue surrounding bones Tendon — anchors muscle to bone Vocabulary Objective 2 of 2
12
Why Is Flexibility Important?
Needed in daily living Reduces chance of injury Increases capacity of joint to move Prevents muscles from shortening Helps relieve muscle soreness Improves Posture Objective 1 of 2
13
Why Is Flexibility Important?
Helps reduce chance of developing low back pain Helps relax muscle tightness from injury, fatigue, and emotional tension Objective 2 of 2
14
Types of Stretching Static — slowly move muscle to stretching point
Dynamic — continuous, slow and controlled Ballistic — bouncing, jerky movement using body’s momentum Isostatic — use a partner to stretch beyond your limit Vocabulary Objective
15
F.I.T. Applied to Flexibility
Increase overload by increasing: Frequency - number of sessions per day or week Intensity - distance the muscle is stretched Time - length of time the position is held, or number of repetitions and sets Objective 1 of 3
16
Principle of Progression
Gradually increase overload by increasing frequency, intensity or time of the exercise Objective 2 of 3
17
Principle of Specificity
Stretching exercises will improve flexibility only in joints exercised Flexibility is specific to each: 1. Individual 2. Joint 3. Sport Objective 3 of 3
18
Flexibility Safety Precautions
Unsafe flexibility exercises Avoid ballistic stretching Don’t use a partner to stretch Start at your appropriate level and progress slowly Stretch by what feels comfortable to you — don’t follow others Combine cardiovascular, muscular strength and endurance exercises to prevent imbalance. Objective
19
Flexibility Assessment
Before beginning testing: Always warm up Avoid ballistic stretching Move in a slow, controlled way Objective
20
Flexibility Minimum principles of training guidelines
Frequency - at least 3 times per week Intensity - stretch slowly until mild tension is felt Time - static: hold stretch for 15 to 30 sec
21
Setting Flexibility Goals
22
Flexibility Exercises
Upper body and torso Neck Triceps Chest and biceps Shoulder 3-prong support side stretch
23
Flexibility Exercises
Lower back stretch Hamstring Groin Quadriceps Calf Achilles tendon Shin
24
Harmful Stretching Positions
Head circles Arm circles Plow Sitting quadriceps stretch 4-count toe touch Hurdle stretch Deep knee bends
25
Record Progress toward Goal
26
Summary Flexibility is the ability to move body joints through a full range of motion The direction of joint movement is limited by the way it is structured Four types of stretching Flexibility is limited by soft tissue which includes ligaments, muscles, and tendons
