Impact from Repeated Use of “Bad Exercises” • Certain exercises or movements put the back at risk and should be avoided Concepts of Fitness and Wellness 6e
Click forlab 13a info Risk Factors for Back Problems • Non-modifiable: • Family history (osteoporosis/joint problems) • Age • Modifiable: • Postural: Poor postural habits • Physical: Poor fitness in low back area • Behavioral: Lifestyle behaviors • Dangerous exercises or movements • Frequent or improper lifting • Extended standing or extended sitting Concepts of Fitness and Wellness 6e
What is Good Posture? • Minimal stress on the vertebral joints and supporting ligaments. • Body segments balanced around the center of gravity Bad Good
Click forlab 13b info Elements of Good Standing Posture • Head centered - chin level • Chest high - not strained • Shoulders down and back • Abdomen flat ("suck and tuck") • Knees straight and relaxed • Feet parallel and weight balanced Concepts of Fitness and Wellness 6e
Causes of Poor Posture • Hereditary • Poor fitness • Lack of knowledge • Bad habits Concepts of Fitness and Wellness 6e
Postural Problems:Scoliosis • Most severe condition • Characterized by a curved spine • Congenital or acquired • Corrected with braces, exercises or operations Concepts of Fitness and Wellness 6e
Postural Problems:Lumbar Lordosis • Most common condition • Characterized by "sway back" posture • Results from weak abdominals and short hip flexors Concepts of Fitness and Wellness 6e
Lumbar Lordosis • Weak abdominals and short hip flexors tip the pelvis forward and increase back strain Concepts of Fitness and Wellness 6e
Proper Posture • Strong abdominals and flexible hip flexors keep the pelvis neutral and the body in alignment Concepts of Fitness and Wellness 6e
Strategies for Promoting Back Health • Postural Influences • Physical Influences • Behavioral Influences Each of these categories is described in subsequent slides Concepts of Fitness and Wellness 6e
Back Care Tips - Postural • When standing keep the lower back flat (stand with one foot on a stool) • When sitting avoid slouching(see graphic on next slide) • When lying keep knees and hips bent (avoid lying on stomach) • When sleeping use a firm mattress Concepts of Fitness and Wellness 6e
Slouching Increases Strain on Low Back • Slouching in a chair increases the pressure on the vertebral disks and can lead to back pain Note: similar position of spine when bending over Concepts of Fitness and Wellness 6e
Click forlab 13c info Back Care Tips - Physical • Strengthen abdominal muscles • Strengthen hip extensors • Stretch hip flexors • Stretch hamstrings Example of Swiss Ball Exercises Example of Strength Machines Concepts of Fitness and Wellness 6e
Back Health Tips - Behavioral • Avoid hazardous exercises • Avoid sudden jerky back movements • Avoid improper lifting and carrying Click for more info Concepts of Fitness and Wellness 6e

Concepts of Fitness and Wellness 6e
Lab 13b InformationEvaluating Posture Return to presentation • Have a partner perform a postural evaluation based on the criteria listed on the evaluation chart. • Discuss any deviations that were moderate or severe and whether you feel the ratings were informative for you.

Poor Lifting Technique • The poor leverage used here to lift a 50 lb box causes extreme forces to be imparted on the spine. • 750 pounds of tensile force on the muscles of the low back • 850 pounds of compressional force on the lumbar disks Concepts of Fitness and Wellness 6e
Back Care Tips:Lifting and Carrying • Stand close and assume a wide base • Maintain normal lordotic curve and bend at the hips and knees • Keep object close to the body’s ‘center of gravity’ • Avoid hyperextending the neck or back when lifting Concepts of Fitness and Wellness 6e
