• Raining to allow joints to move freely through a full, normal, range of motion for any particular sport. Amount of flexibility that is necessary depends on the sport
• Goal is to achieve strength combined with flexibility that can allow a client to better control his or her movements
• Also important in injury prevention (tight muscles)
• Follows the warm up period
• Should never be used as warm up, should only be done after core temperature has been elevated to a point where light perspiration begins.
• If sport is dynamic, such as basketball, flexibility training prior to activity and after the warmup is recommended
• If activity is less dynamic, such as cycling and stair climbing, flexibility training can be performed after training session
Flexibility Training
![Page 3: By Amanda Tang Flexibility, Body- Weight, and Stability Ball Exercise.](https://reader036.fdocuments.us/reader036/viewer/2022082613/5697c0021a28abf838cc34d8/html5/thumbnails/3.jpg)
• Flexibility training is important to those interested in fitness because of the role that optimum flexibility plays in improving movements performance and reducing the opportunity for injury
• Helps eliminate awkward and inefficient movement by allowing joints to move freely though a full normal ROM
• Most common injuries with poor flexibility include lower back pain resulting from tight quadriceps, iliopsoas, and back muscles

Factors Affecting Flexibility
![Page 5: By Amanda Tang Flexibility, Body- Weight, and Stability Ball Exercise.](https://reader036.fdocuments.us/reader036/viewer/2022082613/5697c0021a28abf838cc34d8/html5/thumbnails/5.jpg)
Elasticity
• The ability to return to original resting length after a passive stretch
• Provides a temporary change in length
• Muscle only has this property
Plasticity
• The tendency to assume a new and greater length after a passive stretch, even after the load is removed
• Ligaments and tendons have this property and the other
• Stretching techniques should be designed primarily to produce a this form of elongation if a permanent increase in ROM is the goal
Elasticity and Plasticity
![Page 6: By Amanda Tang Flexibility, Body- Weight, and Stability Ball Exercise.](https://reader036.fdocuments.us/reader036/viewer/2022082613/5697c0021a28abf838cc34d8/html5/thumbnails/6.jpg)
• increase blood flow to the muscle
• increase in the sensitivity if nerve receptors
• increase in the disassociation of oxigen from hemoglobin to myoglobin
• increase in the speed of nerve impulse trasmissions
• reduction in muscle viscosity
• lowering of the energy rates of metabolic chemical reaction
Warm-Up
![Page 7: By Amanda Tang Flexibility, Body- Weight, and Stability Ball Exercise.](https://reader036.fdocuments.us/reader036/viewer/2022082613/5697c0021a28abf838cc34d8/html5/thumbnails/7.jpg)
Specific Warm-Up
• Warm up that includes movements that are an actual part of the activity, such as slow jogging before a run, or light bench presses before a progressing to workout weight
• Best method because it warms up core body temp and serves as rehearsal of the event, allowing complex skills to be performed more effectively
Passive Warm-Up
• Warm up that involves methods such as hot showers, heating pads, or massages
• Advantageous in that it dies not prefatigue client, however, not practical
General Warm-Up
• Warm up that involves basic activities that require movement of the major muscle groups, such as jogging, cycling, or jumping rope
• Increases HR, blood flow, deep muscle temp, respiration rate, viscosity of joint fluids and perspiration
• More appropriate when goal is preparing the body for physical activity
Types of Warm Ups
![Page 8: By Amanda Tang Flexibility, Body- Weight, and Stability Ball Exercise.](https://reader036.fdocuments.us/reader036/viewer/2022082613/5697c0021a28abf838cc34d8/html5/thumbnails/8.jpg)
• Improved balance, joint stability, proprioception and neuromuscular control decrease the incidence of injury
• Heart rate response and oxygen consumption increase
• Strength, stability , balance, posture, proprioception ,and flexibility in pregnancy, these adaptation result in stronger abdominal muscle which help to support the baby, decrease the incidence of back pain, and reduce the changes of accidental falls 262
Body-Weight and Stability Ball Exercises
![Page 9: By Amanda Tang Flexibility, Body- Weight, and Stability Ball Exercise.](https://reader036.fdocuments.us/reader036/viewer/2022082613/5697c0021a28abf838cc34d8/html5/thumbnails/9.jpg)
Static Stretching
• Most common method for flexibility training.
• Uses a slow, constant speed, with the stretched position held for 30 seconds.
• Involves relaxing and lengthening the muscles.
• Does not activate stretch reflex because of low speed, thus, risk of injury lower.
• As stretch is held to a slight discomfort, tension should reduce, if it does not, tension should be diminished.
• Increasing length of time over 30 seconds shows no improvements.
• No real disadvantage if done correctly. Although it may negatively affect dynamic activity performance
• (running, jumping, etc) if done prior.
Ballistic Stretching
• (bouncing) Rapid, jerkey, uncontrolled movements used as a stretching technique. Body parts put into motion, and momentum takes it through the ROM until the muscles are stretched to the limit.
• No longer an acceptable method for increasing ROM.
• 1. Increases danger of exceeding extensibility limits of tissue
• 2. Requires higher energy
• 3. Greater likelihood of muscle soreness
• 4. Activation of stretch reflex creates muscle tension that prevents a full stretch.
Types of Flexibility Training
![Page 10: By Amanda Tang Flexibility, Body- Weight, and Stability Ball Exercise.](https://reader036.fdocuments.us/reader036/viewer/2022082613/5697c0021a28abf838cc34d8/html5/thumbnails/10.jpg)
Dynamic Stretching
• Similar to ballistic, but no bouncing, and includes sports specific movements.
• More movement specific than static stretching techniques.
• May be the most appropriate type of flexibility training for improving movement capability before a workout. If additional flexibility is needed, performance of static flexibility exercises post workout is effective.
Proprioceptive Neuromuscular Facilitation
• Originally developed as a technique to relax muscles that demonstrate increased tone or activity.
• Accepted as a very effective, most superior, method of increasing ROM.
• Usually performed with a partner and use passive, and active movements (concentric, isometric)
• Most common method is the "Hold-Relax Method"
• -take joint into static stretch while relaxed
• -after 10 sec, contract muscle for 6 sec with strong isometric contraction against an external force.
• -partner should not allow client to move
• -after 2-3sec rest, passive stretch performed for 30 sec. resulting in greater stretch.
• Activation of golgi tendon results in less muscle tension in second stretch..
• Injury potential is high and this should not be done one youngsters or untrained. Also more time consumming and other methods increase ROM effectively and more easily.

A 6-foot, 9-inch (206 centimeter), 230-pound (105 kilogram) male client has been preparing for the upcoming basketball season and has been preforming traditional resistance training for the past six months. His personal trainer decides to introduce stability ball exercises into the client’s program. Which of the following guidelines apply to this client?
a. Due to the client’s weight, the personal trainer should slightly under inflate the ball
b. When determining correct ball size, the client’s thighs should be parallel to the ground when siting on the ball with the feet flat on the bottom
c. Because the ball is unstable and the client is so tall, slight deviations from correct technique are acceptable
d. Since the client had been performing resistance training exercises for so long, the personal trainer should direct the client to stop resistance training and preform only stability ball exercises
