An ounce of prevention is worth a ton of cure
Anonymous
You walk into your first jogging class,eager to improve your fitness.You have not exercised regularly and you hope this class will help you get into shape.Your instructor begins with a warm-up and an easy jog around campus.After your run,you feel great and invigorated.The next morning,you wake up and your whole body aches.You do not remember having been run over by a truck.“what should I do now?Withdraw from class stay in bed?Buy stock in ben-gay?When will I be able to move again?”
Participation in fitness activities offers many benefits.These benefits far exceed the risk of injury.When you exercise,as your body adapts to these efforts,you may experience minor aches and soreness.Physical activity also carries some risk of overuse or injury.Fortunately,many of these discomforts are minor,and you will be able to continue or quickly resume your workouts.This chapter discusses how to prevent injuries,in addition to how to recognize their signs and symptoms and what treatments are recommended.It also examines how to maintain a healthy back,since chronic back pain is a common problem.Finally,factors that affect the musculature of the spine and how to avoid lower back injury are covered..
Injury prevention
Prevention is the key to reducing the frequency of injuries.Understanding the cause of injury allows you to stop minor problems before they turn you into the walking wounded.Prevention is far more conductive to wellness than any patch and repair job.There are four main reasons injuries occur:
1 overuse:doing too much too soon or too often,causing a breakdown at the weakest point ankle,achilles tendon,thin,knee,or back.
2 footwear:wearing improper or worn out shoes.
3 weakness and inflexibility:muscles so weak or tight that the slightest unusual twist strains them.
4 mechanical problems:the result of anatomical problems (the way the foot hits the ground,body build,etc.) or using poor form while exercising.
An individually adjusted workload,well-made and well-kept shoes,supplemental toning and stretching exercises,and mechanical improvements will prevent the majority of injuries.
In order to improve or maintain fitness,you must overload,or push,beyond normal demands.Overload is necessary and good up to a point,but you must be able to recover between workouts.The goal is to exercise so that you improve but not so much that you cause overuse,excessive overload leading to injury or illness.Overuse problems commonly occur at the beginning of a new exercise program and account for the majority of injuries,it is estimated that between 25percent and 50percent of athletes visiting sports medicine clinics have sustained overuse injuries.The first four months of a new program are the most critical.The body and muscles must be given time to gradually adapt to the new demands.
