Fitness AssessmentFitness Assessment
FitnessFitness means capacity to exercise. Factors means capacity to exercise. Factors such as a sedentary lifestyle, health problems, such as a sedentary lifestyle, health problems, compromised muscle and skeletal function, compromised muscle and skeletal function, obesity, advanced age, smoking, and high obesity, advanced age, smoking, and high blood pressure can impair a client's fitness and blood pressure can impair a client's fitness and stamina.stamina.

Exercise PrescriptionsExercise Prescriptions
The prescription for an exercise program The prescription for an exercise program involves determining the person's target heart involves determining the person's target heart rate rate
15
Target Heart RateTarget Heart Rate
Target heart rateTarget heart rate means the goal for heart means the goal for heart rate during exercise. It is determined by first rate during exercise. It is determined by first calculating the person's calculating the person's maximum heart ratemaximum heart rate (highest limit for heart rate during exercise). (highest limit for heart rate during exercise). Maximum heart rate is calculated by Maximum heart rate is calculated by subtracting a person's age from 220. subtracting a person's age from 220.
The target heart rate is 60% to 90% of the The target heart rate is 60% to 90% of the maximum heart rate.maximum heart rate.
16
Beginners should not exceed 60%, intermediates can Beginners should not exceed 60%, intermediates can exercise at 70% to 75%, and competitive athletes can exercise at 70% to 75%, and competitive athletes can tolerate 80% to 90% of their maximum heart ratetolerate 80% to 90% of their maximum heart rate..
Exercising at the target rate for 15 minutes (excluding Exercising at the target rate for 15 minutes (excluding the warm-up and cool-down periods) three or more the warm-up and cool-down periods) three or more times per week strengthens the heart muscle and times per week strengthens the heart muscle and promotes the use of fat reserves for energy. promotes the use of fat reserves for energy. Exercising beyond the target heart rate reduces Exercising beyond the target heart rate reduces endurance by increasing fatigue.endurance by increasing fatigue.

1. Fitness Exercise1. Fitness Exercise
Fitness exerciseFitness exercise means physical activity means physical activity performed by healthy adults. Fitness exercise performed by healthy adults. Fitness exercise develops and maintains cardiorespiratory develops and maintains cardiorespiratory function, muscular strength, and endurance function, muscular strength, and endurance (Fig. 24-3). The two categories of fitness (Fig. 24-3). The two categories of fitness exercise are isotonic and isometric.exercise are isotonic and isometric.

Isotonic exerciseIsotonic exercise is activity that involves is activity that involves movement and work. The example is movement and work. The example is aerobic aerobic exerciseexercise, which involves rhythmically moving , which involves rhythmically moving all parts of the body at a moderate to slow all parts of the body at a moderate to slow speed without hindering the ability to breathe. speed without hindering the ability to breathe. In other words, the person can talk In other words, the person can talk comfortably if the exercise is within his or her comfortably if the exercise is within his or her level of fitness. level of fitness.
21
Isometric exerciseIsometric exercise consists of stationary consists of stationary exercises generally performed against a resistive exercises generally performed against a resistive force. force.
Examples include body building, weight lifting, Examples include body building, weight lifting, and less intense activities such as simply and less intense activities such as simply contracting and relaxing muscle groups while contracting and relaxing muscle groups while sitting or standingsitting or standing. .

2. Therapeutic Exercise2. Therapeutic Exercise
Therapeutic exerciseTherapeutic exercise is activity performed by is activity performed by people with health risks or being treated for an people with health risks or being treated for an existing health problem. Clients perform existing health problem. Clients perform therapeutic exercise to prevent health-related therapeutic exercise to prevent health-related complications or to restore lost functionscomplications or to restore lost functions

Active ExerciseActive Exercise
Active exerciseActive exercise is therapeutic activity that the is therapeutic activity that the client performs independently after proper client performs independently after proper instruction. instruction.
For example, clients who have undergone a For example, clients who have undergone a mastectomy learn to exercise the arm on the mastectomy learn to exercise the arm on the surgical sidesurgical side

Passive ExercisePassive Exercise
Passive exercisePassive exercise is therapeutic activity that the is therapeutic activity that the client performs with assistance and is provided client performs with assistance and is provided when a client cannot move one or more parts when a client cannot move one or more parts of the body. of the body.
For example, for clients who are comatose or For example, for clients who are comatose or paralyzed from a stroke or spinal injury, nurses paralyzed from a stroke or spinal injury, nurses perform perform
