What can stretching do as a preventive strategy?

promote dynamic movement that is important for muscle health, balance of forces, and blood flow

what are the benefits of stretching?

• warms up muscles before beginning to work

• helps prevent muscle strains and spasms

• decreases muscle soreness and tender spots

• increases production of joint synovial fluid to reduce friction between joints during movement

• increases range of motion, which promotes increased flexibility

• increases coordination which enhances control of fine motor skills

• increases nutrient supply to the vertebral discs of the spine

• reduces stress and promotes relaxation

how do you stretch safely?

• assume starting position for the stretch

• breathe in deeply as you begin the stretch

• hold stretch for about 10 seconds

• slowly release the stretch as you return to the starting position. repeat stretch if time allows

• never stretch in a painful range. if stretching increases your pain, stop immediately
