Exercise

Definition

Exercise is physical activity that is planned, structured, and repetitive for the purpose of conditioning any part of the body. Exercise is used to improve health, maintain fitness and is important as a means of physical rehabilitation.

Purpose

Exercise is useful in preventing or treating coronary heart disease, osteoporosis, weakness, diabetes, obesity, and depression. Range of motion is one aspect of exercise important for increasing or maintaining joint function. Strengthening exercises provide appropriate resistance to the muscles to increase endurance and strength. Cardiac rehabilitation exercises are developed and individualized to improve the cardiovascular system for prevention and rehabilitation of cardiac disorders and diseases. A well-balanced exercise program can improve general health, build endurance, and slow many of the effects of aging. The benefits of exercise not only improve physical health, but also enhance emotional well-being.
Studies have shown that a consistent, guided exercise program benefits almost everyone from Gulf War veterans coping with fatigue, distress, cognitive problems, and mental health functioning to patients awaiting heart transplants. Exercise in combination with a reduced-calorie diet is the safest and most effective method of weight loss. The United States Department of Agriculture (USDA) food pyramid, called MyPyramid, makes exercise as well as food recommendations to emphasize the interconnectedness between exercise, diet, and health.

Precautions

Before beginning any exercise program, an evaluation by a physician is recommended to rule out potential health risks. Once health and fitness level are determined and any physical restrictions identified, the individual's exercise program should begin under the supervision of a health care or other trained professional. This is particularly true when exercise is used as a form of rehabilitation. If symptoms of dizziness, nausea, excessive shortness of breath, or chest pain are present during exercise, the individual should stop the activity and inform a physician about these symptoms before resuming activity. Exercise equipment must be checked to determine if it can bear the weight of people of all sizes and shapes. Individuals must be instructed in the proper use of exercise equipment in order to prevent injury.

Description

Range of motion exercise

Range of motion exercise refers to activity aimed at improving movement of a specific joint. This motion is influenced by several structures: configuration of bone surfaces within the joint, joint capsule, ligaments, tendons, and muscles acting on the joint. There are three types of range of motion exercises: passive, active, and active assists. Passive range of motion is movement applied to a joint solely by another person or persons or a passive motion machine. When passive range of motion is applied, the joint of an individual receiving exercise is completely relaxed while the outside force moves the body part, such as a leg or arm, throughout the available range. Injury, surgery, or immobilization of a joint may affect the normal joint range of motion. Active range of motion is movement of a joint provided entirely by the individual performing the exercise. In this case, there is no outside force aiding in the movement. Active assist range of motion is described as a joint receiving partial assistance from an outside force. This range of motion may result from the majority of motion applied by an exerciser or by the person or persons assisting the individual. It also may be a half-and-half effort on the joint from each source.

Strengthening exercise

Strengthening exercise increases muscle strength and mass, bone strength, and the body's metabolism. It can help attain and maintain proper weight and improve body image and self-esteem. A certain level of muscle strength is needed to perform daily activities such as walking, running, and climbing stairs. Strengthening exercises increase muscle strength by putting more strain on a muscle than it is normally accustomed to receiving. This increased load stimulates the growth of proteins inside each muscle cell that allow the muscle as a whole to contract. There is evidence indicating that strength training may be better than aerobic exercise alone for improving self-esteem and body image. Weight training allows one immediate feedback, through observation of progress in muscle growth and improved muscle tone. Strengthening exercise can take the form of isometric, isotonic and isokinetic strengthening.

Isometric exercise

During isometric exercises, muscles contract. However, there is no motion in the affected joints. The muscle fibers maintain a constant length throughout the entire contraction. The exercises usually are performed against an immovable surface or object such as pressing one's hand against a wall. The muscles of the arm are contracting but the wall is not reacting or moving in response to the physical effort. Isometric training is effective for developing total strength of a particular muscle or group of muscles. It often is used for rehabilitation since the exact area of muscle weakness can be isolated and strengthening can be administered at the proper joint angle. This kind of training can provide a relatively quick and convenient method for overloading and strengthening muscles without any special equipment and with little chance of injury.

Isotonic exercise

Isotonic exercise differs from isometric exercise in that there is movement of a joint during the muscle contraction. A classic example of an isotonic exercise is weight training with dumbbells and barbells. As the weight is lifted throughout the range of motion, the muscle shortens and lengthens. Calisthenics are also an example of isotonic exercise. These would include chin-ups, push-ups, and sit-ups, all of which use body weight as the resistance force.

Isokinetic exercise

Isokinetic exercise utilizes machines that control the speed of contraction within the range of motion. Isokinetic exercise attempts to combine the best features of both isometrics and weight training. It provides muscular overload at a constant preset speed while a muscle mobilizes its force through the full range of motion. For example, an isokinetic stationary bicycle set at 90 revolutions per minute means that no matter how hard and fast the exerciser works, the isokinetic properties of the bicycle will allow the exerciser to pedal only as fast as 90 revolutions per minute. Machines known as Cybex and Biodex provide isokinetic results; they generally are used by physical therapists.

Cardiac rehabilitation

Exercise can be very helpful in prevention and rehabilitation of cardiac disorders and disease. With an exercise program designed at a level considered safe for the individual, people with symptoms of heart failure can substantially improve their fitness levels. The greatest benefit occurs as muscles improve the efficiency of their oxygen use, which reduces the need for the heart to pump as much blood. While such exercise does not necessarily improve the condition of the heart itself, the increased fitness level reduces the total workload of the heart. The related increase in endurance also should translate into a generally more active lifestyle. Endurance or aerobic routines, such as running, brisk walking, cycling, or swimming, increase the strength and efficiency of the muscles of the heart.

Preparation

A physical examination by a physician is important to determine if strenuous exercise is appropriate or detrimental for an individual, especially when the exercise program is designed for rehabilitation. Before exercising, proper stretching is important to prevent the possibility of soft tissue injury resulting from tight muscles, tendons, ligaments, and other joint-related structures.

Aftercare

Proper cool down after exercise is important in reducing the occurrence of painful muscle spasms. Proper cool down stretching also may decrease frequency and intensity of muscle stiffness the day following any exercise program.

Risks

Improper warm up can lead to muscle strains. Overexertion without enough time between exercise sessions to recuperate also can lead to muscle strains, resulting in inactivity due to pain. Stress fractures also are a possibility if activities are strenuous over long periods without proper rest. Although exercise is safe for the majority of children and adults, there is still a need for further studies to identify potential risks.

Normal results

Significant health benefits are obtained by including a moderate amount of physical exercise in the form of an exercise prescription. This is much like a drug prescription in that it also helps enhance the health of those who take it in the proper dosage. Physical activity plays a positive role in preventing disease and improving overall health status. People of all ages, both male and female, benefit from regular physical activity. Regular exercise also provides significant psychological benefits and improves quality of life.

Abnormal results

Exercise burnout may occur if an exercise program is not varied and adequate rest periods are not taken between exercise sessions. Muscle, joint, and cardiac disorders have been noted among people who exercise. However, they often have had preexisting or underlying illnesses.

Key Terms

Aerobic: Exercise training that is geared to provide a sufficient cardiovascular overload to stimulate increases in cardiac output.
Calisthenics: Exercise involving free movement without the aid of equipment.
Endurance: The time limit of a person's ability to maintain either a specific force or power involving muscular contractions.
Osteoporosis: A disorder characterized by loss of calcium in the bone, leading to thinning of the bones. It occurs frequently in postmenopausal women.

G, Supination: Extension of the forearm to bring the palm of the hand upward. H, Pronation: Movement of the forearm in the extended position that brings the palm of the hand to a downward position. I, Inversion: Movement of the ankle to turn the sole of the foot medially. J, Eversion: Movement of the sole of the foot laterally. From Lammon et al., 1995.See accompanying figure.resistance e's (resistive e's) activities designed to increase muscle strength, performed against an opposing force; the resistance may be either isometric, isotonic, or isokinetic.static exercise muscle-setting exercise.static stretching e's the placement of muscles and connective tissues at their greatest length by steady force in the direction of lengthening. Short duration forces can be obtained manually, but special traction devices, splints, and casts are generally used to apply low-intensity forces for prolonged periods (30 minutes or longer). Warming the soft tissue before or during stretching will generally facilitate lengthening.exercise stress tests tests used in exercise testing.exercise testing a technique for evaluating circulatory response to physical stress; it involves continuous electrocardiographic monitoring during physical exercise, the objective being to increase the intensity of physical exertion until a target heart rate is reached or signs and symptoms of cardiac ischemia appear. Called also stress testing.
Clinical exercise testing has become an important tool in screening for and diagnosing early ischemic heart disease that cannot be detected by a standard resting EKG, and in predicting the probability of the development of the condition in later years. The technique cannot determine the location of the lesion causing cardiac ischemia and therefore must be supplemented with angiocardiography when coronary occlusion is detected.
Common forms of exercise used include the treadmill and the bicycle ergometer. These procedures must be performed in a clinical setting where health care personnel are available in the event symptoms develop during exercise, such as dyspnea, vertigo, extreme fatigue, severe arrhythmias, or other abnormal EKG readings.
Exercise testing also may be used to assess the pulmonary status of a patient with a respiratory disease. As the patient performs specific exercises, blood samples are drawn for blood gas analysis, and ventilatory function tests such as tidal volume, total lung capacity, and vital capacity are conducted.therapeutic exercise the scientific use of bodily movement to restore normal function in diseased or injured tissues or to maintain a state of well-being; called also corrective exercise. As with any type of therapy, a therapeutic exercise program is designed to correct specific disabilities of the individual patient. The program is evaluated periodically and modified as indicated by the patient's progress and response to the prescribed regimen. Exercises affect the body locally and systemically and bring about changes in the nervous, circulatory, and endocrine systems as well as the musculoskeletal system.
Among the types of therapeutic exercise are those that (1) increase or maintain mobility of the joints and surrounding soft tissues, (2) develop coordination through control of individual muscles, (3) increase muscular strength and endurance, and (4) promote relaxation and relief of tension.Joint Mobility. In the absence of a disability that prohibits mobility, the regular day-to-day activities of living maintain the normal movements of the joints. If, however, motion is restricted for any reason, the soft tissues become dense and hard and adaptive shortening of the connective tissues takes place. These changes begin to develop within four days after a joint has been immobilized and are evident even in a normal joint that has been rendered immobile. It is for this reason that therapeutic exercises to prevent loss of joint motion are so important and should be begun as soon as possible after an injury has occurred or a disease process has begun.
Prevention of the loss of joint motion is much less costly and time-consuming than correction of tissue changes that seriously impair joint mobility. It is recommended that each joint should be put through its full range of motion three times at least twice daily. If the patient is not able to carry out these exercises, he is assisted by a therapist or member of the family who has been instructed in the exercises. Inflammation of the joint, as in arthritis, may cause some pain on motion, and so passive exercises are done slowly and gently with the joint as relaxed as possible. Procedures that stretch tight muscles to increase joint motion should be done only by a skilled therapist who understands the hazards of fracture and bleeding within the joint, which can occur if the exercises are done improperly or too strenuously.Muscle Training. Exercises of this type are taught to the patient who has lost some control over a major skeletal muscle. By learning precise and conscious control over a specific muscle, the patient is able to strengthen and coordinate its movement with normal motor patterns and thus enhance mobility. Muscle training or neuromuscular re-education demands full cooperation of the patient, who must be capable of understanding the purpose of the exercises, following directions, and giving full attention to the muscle isolated for retraining. The sessions are held in a quiet, comfortable atmosphere to facilitate concentration by the patient.
The development of conscious control over individual muscles is useful in the rehabilitation of patients with a variety of disorders, including physical trauma, diseases such as poliomyelitis that affect the motor neurons, and congenital disorders such as cerebral palsy. It involves a systematic program of sequential activities under the direction of a therapist knowledgeable in the technique. Although it requires much effort on the part of the patient and the therapist, the attainment of muscle control and coordination is a satisfying reward.Muscle Strength and Endurance. Improvement of muscle strength and endurance is particularly important in the rehabilitation of patients whose goal is to return to an active and productive life after a debilitating illness or disabling injury. The exercises are prescribed according to the individual needs of the patient and usually involve more than one group of muscles.
Strengthening (force increasing) exercises are prescribed after an examination has shown weakness in individual muscles or muscle groups. These exercises are usually administered with relatively high resistance and few (3 to 10) repetitions. A group of exercises, called a set, is followed by a few minutes of rest. Three to 5 sets for a muscle or group constitute one bout of exercises. Strengthening exercises are often performed daily in early stages of rehabilitation, but less often later in treatment.
Endurance exercises stimulate changes in the involved muscle or muscles, resulting in improved capacity for repeated contraction (e.g., increased ability to use metabolites). When conducted over a sufficient length of time and with several muscle groups, they may also produce central effects of the cardiovascular system (see cardiovascular exercise). Endurance exercises employ relatively low resistance and numerous (15 or more) repetitions. Endurance exercises are generally administered daily.Relief of Tension. Exercises that promote relaxation of the muscles and provide relief from the effects of tension are useful in a wide variety of disorders ranging from mild tension headache to insomnia. Patients who are especially tense may require several sessions of instruction in relaxation before they can learn the technique.Williams' e's (Williams' flexion e's) a therapeutic exercise regimen used in the treatment of low back pain; it seeks to reduce lumbar lordosis through flexion of the lumbar spine and strengthening of the abdominal musculature.

(eksĕr-sīz) 1. Active: Planned repetitive physical activity structured to improve and maintain physical fitness. 2. Passive: motion of limbs without effort by the patient. [L. exercitire, to train hard]

exercise

(ek'ser-siz?) [L. exercitus, trained, drilled] A physical or mental activity performed to maintain, restore, or increase normal capacity. Physical exercise involves activities that maintain or increase muscle tone and strength, esp. to improve physical fitness or to manage a handicap or disability. See: table; physical fitness; risk factor; sedentary lifestyle

Daily physical activity for a minimum of 35 min will increase exercise capacity and the ability to use oxygen to derive energy for work, decrease myocardial oxygen demands for the same level of work, favorably alter lipid and carbohydrate metabolism, prevent cardiovascular disease, and help to control body weight and body composition. An exercise program should include developing joint flexibility and muscle strength, esp. in the trunk and limbs. This is of particular importance as people age. Exercise can have a beneficial effect in patients with depression or anxiety. It is thought to have a positive effect on balance, endurance, attitude, and outlook.

An exercise program should be neither begun nor continued if the individual or the person prescribing the exercise program has evidence that the activity is painful or harmful. Persons have died while exercising, and heavy physical exertion may precede acute myocardial infarction, particularly in people who are habitually sedentary. See: exercise prescription

Mental exercise involves activities that maintain or increase cognitive faculties. Daily intellectual stimulation improves concentration, integration, and application of concepts and principles; enhances problem-solving abilities; promotes self-esteem; facilitates self-actualization; counteracts depression associated with social isolation and boredom; and enhances the quality of one's life. This is particularly important during aging. See: reminiscence therapy

Most of the negative aspects of aging can be either altered or diminished by a lifelong healthy lifestyle. For example, the loss of physical fitness and strength, an inevitable consequence of aging, can be altered by an individualized fitness and strength program. Progressive loss of bone mass due to osteoporosis may be either prevented or slowed by a program of regular exercise. Loss of cardiac fitness can be forestalled by an ongoing aerobic fitness program. Many cases of type 2 diabetes can be controlled by exercise and an appropriate diet. Arthritic stiffness and loss of flexibility can be influenced favorably by exercise, e.g., by walking and jogging; for patients who experience joint pain with impact exercise, swimming is an alternative. Obesity and loss of muscle mass can be prevented or minimized.

Exercise stimulates release of endorphins, and people who participate in regular exercise programs express positive feelings toward living. Exercise programs can be adapted for patients who are confined to wheelchairs. An important consideration for any exercise program is that it be enjoyable. No matter how beneficial the program may be, if it is not enjoyable or rewarding, it will not be continued.

active exercise

A type of bodily movement performed by voluntary contraction and relaxation of muscles.

aerobic exercise

Exercise during which oxygen is metabolized to produce energy. Aerobic exercise is required for sustained periods of physical exertion and vigorous athletic activity. See: anaerobic exercise

anaerobic exercise

High-intensity exercise, such as sprinting or weight lifting, that places more demand on muscles than oxygen delivery can match. When this occurs, glucose is metabolized for its stored energy without using oxygen as a reactant. Adenosine triphosphate (ATP) is produced rapidly, as well as the byproduct, lactic acid. See: aerobic exercise.

aquatic exercise

The use of a pool or an immersion tank filled with water for exercise. Such exercises may be used to improve balance and gait, enhance physical endurance, mobilize joints, and/or strengthen or stretch muscles. See: hydrotherapy

assistive exercise

A type of bodily movement performed by voluntary muscle contractions that are augmented by an extrinsic force such as a clinician or mechanical device.

Bates exercise

See: Bates exercises

breathing exercise

Exercise that enhances the respiratory system by improving ventilation, strengthening respiratory muscles, and increasing endurance. It is used in pulmonary rehabilitation

Buerger postural exercise

See: Buerger, Leo

Codman exercise

See: Codman exercise

concentric exercise

A form of isotonic exercise in which the muscle fibers shorten as tension develops. See: concentric muscle contraction; eccentric muscle contraction

corrective exercise

Use of specific exercises to correct deficiencies caused by trauma, inactivity, muscular imbalances, poor flexibility, or biomechanical inadequacies.

dynamic stabilization exercise

Stabilization exercise.

eccentric exercise

An exercise in which there is overall lengthening of the muscle in response to an external resistance. See: concentric muscle contraction; eccentric muscle contraction

flexibility exercise

An activity, e.g., stretching, designed to increase joint range of motion and extensibility of muscle.

free exercise

An exercise carried through with no external assistance.

isokinetic exercise

An exercise with equipment that uses variable resistance to maintain a constant velocity of joint motion during muscle contraction, so that the force generated by the muscle is maximal through the full range of motion.

ISOMETRIC EXERCISE: Isometric exercise of the upper extremities

isometric exercise

Contraction and relaxation of a skeletal muscle or group of muscles in which the force generated by the muscle is equal to the resistance. There is no change in muscle length, and no movement results. See: illustration Synonym: muscle-setting exercise; static exercise

isotonic exercise

An active muscle contraction in which the force exerted remains constant and muscle length changes.

Kegel exercise

See: Kegel exercise

kinetic chain exercise

An exercise that requires the foot (or hand) to apply pressure against a plate, pedal, or ground. This rehabilitation concept was determined by the anatomical functional relationship in the lower extremities. It also applies to the upper extremities. Kinetic chain describes how forces occur during human motion and how segments of the body are linked together. Kinetic chain exercises can either be open or closed. Open kinetic chain exercises are unrestricted movements in space of a peripheral segment of the body. Closed kinetic chain exercises are movements in which the distal segment meets with external resistance and remains fixed. Closed kinetic chain exercises are more functionally based than open chain exercises.

muscle-setting exercise

Isometric exercise.

neurobic exercise

Brainteasers, association tasks, calculations, puzzles, and other mental and physical exercises designed to stimulate thinking, problem solving, and other cerebral functions.

passive exercise

Passive motion.

pelvic floor exercise

Kegel exercise.

pendulum exercise

Codman exercise.

progressive resistive exercise

Abbreviation: PRE
A form of active resistive exercise based on a principle of gradual increase in the amount of resistance in order to achieve maximum strength.

RANGE-OF-MOTION EXERCISES

range-of-motion exercise

Movement of a joint through its available range of motion. It can be used to prevent loss of motion. See: illustration

regressive resistive exercise

Abbreviation: RRE
A form of active resistive exercise that advocates gradual reduction in the amount of resistance as muscles fatigue.

relaxation exercise

An exercise (such as yoga, tai chi, dance, prayer, or meditation) that induces a relaxation response.

resistance exercise

Exercise in which a muscle contraction is opposed by force to increase strength or endurance. If the resistance is applied by using weights, it is mechanical resistance; if applied by a clinician, it is manual resistance. Synonym: resistive exercise

resistive exercise

Resistance exercise.

stabilization exercise

The application of fluctuating resistance loads while the patient stabilizes the part being trained in a symptom-free position. Exercises begin easily so that control is maintained, and progress in duration, intensity, speed, and variety. Synonym: dynamic stabilization exercise

static exercise

Isometric exercise.

stretching exercise

A therapeutic exercise maneuver, using physiological principles, designed to increase joint range of motion or extensibility of pathologically shortened connective tissue structures.

therapeutic exercise

The use of physical activity or training as a means of improving flexibility, health, strength, or well being; fostering recovery from injury or surgery; preventing complications of injury or illness; or improving or maintaining functional performance. Therapeutic exercise interventions may include techniques to improve motion, strength, motor control, muscle and cardiopulmonary endurance, and efficiency, posture, balance, and coordination. * These estimates are approximate and can serve only as a general guide.

exercise

Muscular activity undertaken for the promotion of health and for the pleasure inherent in the use of the body. Modern sedentary life involves a dangerous degree of under-exertion and much of the bodily disorder suffered today can be attributed to the use of artificial energy sources to replace the use of one's own musculature.

Patient discussion about exercise

Q. Do you exercise at all? If so, what exercise do you perform and why? What are it's benefits? I am looking to incorporate different routines and exercises into my workouts and would like your assistance.A. i do 60 pushups,60 situps, and run 2 miles in 15 mins. then lift weights,my whole work out lasts about an hour a day.

Q. How much exercise should I do. I am very fond of exercise. But I get tired soon and loosing my energy. How much exercise should I do?A. I am glad that you are fond of something which is vital for healthy living. Experts recommend 30-60 minutes of exercise per day. The 60-minute suggestion is based on the National Academy of Science's ideal recommendation for people who are trying to lose weight. But you'll get real health benefits (and burn lots of calories) even if you don't work out that much, especially if you haven't been exercising at all up to now. While 30 minutes of physical activity is considered enough to lower your risk of heart disease, stroke, and high blood pressure, even 10 minutes a day will do you good. Remember that you don't have to do all your exercise in one session: A 30-minute aerobics workout in the morning, a 20-minute walk after work, and 10 minutes of mopping the floor after dinner can do the trick. (Don't forget to include some strength training and stretching in your workouts, too.)

Q. How do you motivate yourself to exercise? I have a problem- I can easily get myself to go to work and other strenuous things, but when I need to get myself out for some exercise, which is only for me, I don’t find the energy for that. Does anyone have any tips how to encourage myself?A. Try to change to an exercise you enjoy. You can also exercise with a friend, and the commitment to him may give you another push. Another option is to join a regular exercise program in a gym. Good luck!
