Exercise • Introduction • Exercise or purposeful physical activities ØBeneficial to all age groups ØSedentary lifestyle is a health risk ØIt is Individualized ØNurses assess fitness level before initiating exercise program Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment • Fitness means : capacity to exercise ØFactors interfering with fitness: sedentary lifestyle, health problems, impaired musculoskeletal function, obesity, advanced age, smoking, and high blood pressure ØBefore exercise assessment of fitness level is necessary ØAssessment techniques: measuring body composition, evaluating trends in vital signs, performing fitness tests Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Body composition: The amount of lean body tissue versus fat Ø Determined by height, weight, body-mass index, skin fold thickness, and mid arm muscle circumference Ø Inactivity without reduced food intake leads to obesity Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Examples of measurements Body mass index (BMI) is a number based on a person's weight and height that provides a way to estimate the effect of weight on health. Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Vital signs: temperature, pulse rate, respiratory rate, and blood pressure Ø Reflect a person’s physical status Ø Elevated vital signs while resting may indicate life-threatening cardiovascular symptoms during exercise Ø Modified exercise: vital signs may decrease Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Fitness tests objectively measure current fitness level and potential for safe exercise. Also helps to determine safe/exercise plan v Methods Ø Stress electrocardiogram (EEG) Ø Ambulatory electrocardiogram (ECG) and Ø Submaximal fitness test Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Stress electrocardiogram Ø Tests electrical conduction through the heart during maximal activity(acute care/clinic). Ø Monitored – HR/R, BP, breathe, dizzy, CP Ø Pulse oximeter measures peripheral oxygenation v Test stopped if abnormal heart rhythm, cardiac ischemia (impaired blood flow to the heart), elevated blood pressure, or exhaustion occurs Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Stress Electrocardiogram Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Ambulatory electrocardiogram is Ø Continuous recording of heart rate and rhythm during normal activity. (client wears a Holter monitor for 24 hours, no shower, avoid magnets, metal detectors, high voltage , electrical blankets) Ø Used when a client has had prior cardiacrelated symptoms or when a stress electrocardiogram is contraindicated Ø Assessment: heart’s response to normal activity, cardiac rehabilitation, and medical therapy Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Ambulatory electrocardiogram Cont’d Ø Client keeps a diary of the time and type of activities performed/medication /symptoms Ø Physician compares the client’s diary with the electrocardiogram. Ø Test results helps to determine any abnormal oxygenation to the heart or abnormal rhythm during any activity. Ø Physician will advice the client.

Client with Holter monitor/ Readings Copyright © 2013 Wolters Kluwer Health | Lippincott Williams

Fitness Assessment (cont’d) • Step test is Ø Submaximal fitness test: timed stepping activity Ø Variations: Harvard Step Test; Queens College Step Test; Chester Step Test Ø Client steps up and down at prescribed height. Shorten time when client develops discomfort. Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Step Test Cont’d Ø Uses a metronome or stopwatch to keep track of the rate and the time Ø Recovery index is then calculated: guide for determining a person’s fitness level. Ø How- see example book. Table 24 Ø Step test should be used with caution. Certified CPR/Automatic cardiac defibrillator personnel should be at hand Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Walk-a-mile test Ø Measures the time it takes a person to walk 1 mile, on flat surface. Time is calculated start/finish. Interpret results using guidelines in table 24 -2 Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Exercise Prescriptions • Target heart rate means Ø Goal for heart rate during exercise. It is determined by calculating Ø Maximum heart rate: (highest limit for heart rate during exercise); Howsubtract client’s age from 220 Ø Exercising beyond target heart rate reduces endurance by increasing fatigue. Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Fitness Assessment (cont’d) • Metabolic energy equivalent (MET) v Because fitness levels vary: exercise prescribed by metabolic energy equivalent (MET) Ø It is a Measure of energy and oxygen consumption during exercise Ø The prescribed amount the person’s cardiovascular system can safely support. (Table 24 -3). Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Types of Exercise • Exercise is done to promote fitness/outcomes. • There are 2 types: Fitness & Therapeutic exercises • Fitness exercise: develops and maintains cardiorespiratory function, muscular strength, endurance v 2 categories q Isotonic q Isometric Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Types of Exercise (Cont’d) • Isotonic exercise v Involves movement and work v Increases cardiorespiratory function v Prime Examples q Aerobic exercise-performed at moderate to slow speed. At the person’s own comfort level Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Types of Exercise (cont’d) • Isometric exercise v Stationary exercise, usually against resistance v Increases circulation but does NOT promote cardiorespiratory function q Weight lifting q Body building Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Types of Exercise (cont’d) • Therapeutic exercise: activity performed by people with health risks that prevents complications and restores lost function v May be Isotonic or isometric q Active exercise: performed independently by client after instruction to a weakened part of body q Passive exercise: performed by client with assistance when client is unable to move body parts. For e. g. after stroke, ROM, or CPM. Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Types of Exercise (cont’d) • Range-of-motion exercises v Therapeutic activities to move joints v Performed to assess joint flexibility; maintain joint mobility and flexibility in inactive clients; prevent ankylosis( permanent loss of joint movement); stretch joints for strenuous activities; and evaluate response to therapeutic exercise program v Performed for care of inactive client Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Types of Exercise (cont’d) • Continuous passive motion machine Ø Electrical device that supplements or substitutes for manual ROM; for clients with burn injuries or knee and hip replacement surgery Ø Produces 0° to 110° motion, 2 to 10 times a minute; initial setting is very low and is increased each day Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Range of Motion of the Knee With a Continuous Passive Motion Machine (Refer to

Functions of CPM Machine v. Restores and increase joint ROM v. Prevents the pooling of venous blood v. Decreases the risks of blood clots v. Accelerates the healing of wounds /synovial fluids circulates around the joints. Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

Nursing Implications • DPH has established guidelines for Physical activity ( Table 24 -5) • Nursing diagnoses to be treated with activity or exercise regimen v Impaired physical mobility v Disuse syndrome v Unilateral neglect v Delayed surgical recovery v Activity intolerance Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

General Gerontologic Considerations • Older Adults: • Balance physical activity with rest • Shortness of breath, increased heart rate indicates activity level beyond tolerance • Eliminate intake of caffeinated or alcoholic beverages before or during physical activity • Water preferred for fluid replacement • Encourage to join organizations, social clubs Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

General Gerontologic Considerations (cont’d) • Families, caregivers of cognitively impaired v Encourage physical activities v Daily active ROM exercises in short sessions v If client is inactive, daily passive ROM exercises prevents muscle atrophy and disuse syndrome Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins

General Gerontologic Considerations (cont’d) • Swimming or exercising in water is less stressful on joints, beneficial for older adults • Many physically challenging sports offer categories for older adults • Safe shoes with nonskid soles can prevent falls • Falls add to morbidity and mortality rates Copyright © 2013 Wolters Kluwer Health | Lippincott Williams & Wilkins
