1. Static vs. Dynamic StretchingAn overview of which type is betteru3049124

2. Overview What is Static Stretching? What is Dynamic Stretching? Benefits of each type Negative effects of each type My opinion

3. What is Static Stretching? Static stretching involves passively stretching a muscle to a point of tension and holding the stretch Gradual lengthening of a muscle to an elongated position and holding for a period of time

4. Once first initial stretch is completed the muscle relaxes and is able to be stretched to greater length The joint is moved through its range of motion

5. Hamstring Static Active Stretch

6. What is Dynamic Stretching? Stretching whilst moving Utilizes momentum from form, static-active stretching strength Propels the muscle into an extended range of motion

7. Dynamic stretching increases range of movement, blood and oxygen flow to soft tissues prior to exertion Utilizes three main concepts: speed of movement, momentum and active muscular effort Unlike Static stretching the Dynamic stretch is not held

8. Dynamic Hamstring Stretch

9. ComparisonBenefits of Static Stretching Benefits of Dynamic Stretching Good for older aged subjects Increase in performance of vertical jump, sprinting and Long term benefit for increasing strength. ROM Sports specific movements. May help prevent muscular injuries (especially LT) Increased body temperature, heart rate and blood flow. Corrects Muscular Imbalances Increased ROM (unsure of LT Decreased stiffness and viscosity effects) Increased elasticity

10. Comparison Negative effects of Static Stretching Negative effects of Dynamic Stretching Negative effect on some Unsure of Long term effects performances; strength, jumping and sprints High intense movements on joints and muscles, can injure if done May affect the neurological incorrectly sensitivity (decreased sensitivity) Negative effect on acceleration May result in decreased body temperature May result in musculoskeletal injuries

11. Opinion Time Sports dependent Age dependent Rehabilitation process/Injury prone Specific muscle that needs to be targeted Long term results of Dynamic Stretching?
