Robbins/Powers/Burgess

Chapter 8 Objectives

After reading this chapter you will be able to:

Identify four main reasons injuries occur.

Give three tips for avoiding an overuse injury.

Explain how muscle weakness and inflexibility contribute to injuries.

Identify four common muscle imbalances.

List and explain the general recommendations for treatment of common injuries (P.R.I.C.E.).

Describe the basic causes and treatment of ankle sprain, blisters, bursitis, chafing, hells spur syndrome, iliotibial band syndrome, muscle camp, muscle soreness, muscle strain, patellofemoral syndrome, plantar fascitis, shin splints, side stitch, stress fracture, and tendonitis.

Identify the symptoms of injury that indicate the need for medical attention.

Explain two vital components of rehabilitation needed to resume activity safely without injury.

Identify the two most important keys to preventing lower back pain.

Describe exercises recommended to reduce the risk of lower back pain.

Four Main Reasons for Injury

Overuse

Doing too much too soon or too often, causing a breakdown at the weakest point.

Improper equipment

Good footwear is paramount.

Weakness and inflexibility

Muscles so weak or tight that the slightest unusual twist strains them.

Common muscle imbalances – calf/shin, front/back of thigh, low back/stomach, chest, upper back.

Mechanical problems

The result of biomechanical/anatomical problems (the way the foot hit the ground) or using poor form while exercising.

Preventing Injury

Warm up properly.

Progress slowly. Increase the duration of your workout no more than 10% weekly. Do not increase both intensity and duration during the same week.

Exercise regularly. Alternate an impact activity with a low impact or non-impact activity.

Cool down.

Stretch for flexibility.

Try cross training.

Drink water before, during, and after exercise.

Modify workouts in extreme heat or cold.

Pay attention to pain. Listen to your body. Get enough rest in order to be fully recovered by your next workout.

Wear good, well-fitting shoes.

Cool down.

Overload and Overuse

Figure 8-1

Recommended Treatment for Common Injuries – P.R.I.C.E.

P.R.I.C.E. assists in the body’s healing process and helps decrease swelling so healing can begin.

P – Protect from further injury.
R – Rest for at least 24 to 72 hours.
I – Ice to reduce pain and swelling (10 minutes to areas with little fat or muscle (fingers), 15-30 minutes for larger areas (knee), 30-45 minutes for areas with large amounts of fat or muscle (thigh) every 3 to 4 hours for 48 to 72 hours or longer if swelling persists.
C – Compress with an elastic wrap to decrease swelling. (Not too tight. Loosen if throbbing occurs and remove when sleeping.)
E – Elevate as often as possible. When sleeping, raise the end of the bed.

Heat and Pain Relievers

Heat applied too early will increase blood flow, swelling, and inflammation.

Use heat after swelling has completely subsided (24-72 hours on the average).

Stick with ice for the first 48-72 hours.

Aspirin or ibuprofen can reduce pain and inflammation of minor sprains, strains, and tendonitis.

Common Sports-Related Injuries

Ankle sprain

Blisters

Bursitis

Chafing

Heel spur

Iliotibial band syndrome

Muscle cramp

Muscle soreness

Muscle strain

Patellofemoral syndrome

Plantar fasciitis

Shin splints

Side stitch

Stress fracture

Tendinopathy

Symptoms and treatment for these conditions are found in Table 8-4.

When to Seek Medical Help

The injury is extremely painful and does not feel better in a day or two.

There is joint pain lasting more than 2 days or tenderness when you press on a specific spot.

There is loss of strength or range of motion.

The limb gives way when you try to use it.

You heard a distinct pop or snap when the injury occurred.

The injured area looks misshapen or has unusual lumps other than swelling.

There is numbness or tingling in the injured area.

Getting Back into Action after an Injury

Move the injured part as early as possible, within a pain-free range to regain flexibility.
After obtaining 80% pain-free range of motion, begin to build strength.
Gradually work your way back to your former activity level. Overload should be gradual.

Ways to Improve Back Health

Stretch and strengthen.
Use good sitting posture.
Use good standing posture.
Change positions frequently.
Use good sleeping posture.
Use good lifting techniques.
Don’t overdo it.
Keep active.
Manage your weight.
Distribute the load.

Exercises for the Lower Back

Figure 8-3

Low Back Injuries

Muscles may be injured by lifting, bending, twisting or poor mechanics.
For sore achy back muscles, ice for 20 minutes or alternate ice and heat every 20 minutes.
If back pain doesn’t decrease in a few days or pain is severe, it may indicate intervertebral disc injury. Consult a physician.

Rx for Action

Check the inner side of the midsole of your shoes for wrinkles, which indicate they have been compressed by daily impact and need to be replaced.

While waiting in line, clasp hands behind your back and pull elbows back to strengthen postural muscles.

While watching TV, do 20 to 30 abdominal crunches or 5 to 10 back extensions.

Put on your favorite music and do the back exercise program in this chapter.
