Fitness and Therapeutic Exercise

Fitness and Therapeutic Exercise: Definitions and Terminology

• Active Exercise enhances muscle strength and endurance through physical activity performed by an individual.
• Aerobic Exercise improves cardiovascular fitness by increasing heart rate and breathing through activities like running or swimming.
• Body Composition is the ratio of lean body mass to fat mass, crucial for assessing health and fitness levels.
• Metabolic Energy Equivalent (MET) estimates the amount of oxygen used during physical activity to gauge exercise intensity.
• Target Heart Rate is the ideal heart rate range during exercise for maximizing cardiovascular benefits, typically as a percentage of maximum heart rate.

Benefits of Regular Exercise

• Regular exercise can mitigate chronic diseases such as cardiovascular disease, type 2 diabetes, and certain cancers.
• Exercise improves mental health by reducing anxiety and depression, enhancing cognitive function, and lowering dementia risk.
• Weight management is improved with exercise, preventing weight regain after loss for overall health and longevity.
• Physical function and mobility are improved, especially in older adults, reducing the risk of falls and injuries.
• Increased energy levels, better sleep, and improved mood results in enhanced quality of life.

Types of Exercises

• Isotonic Exercise involves muscle contraction with movement to build strength and endurance, like lifting weights or performing squats.
• Isometric Exercise involves muscle contraction without movement like holding a plank, which helps maintain muscle strength.
• Isokinetic Exercise involves muscle contraction at a constant speed often using specialized equipment, beneficial for rehabilitation.
• Passive Exercise is movement performed by an external force for those unable to move independently, useful in rehabilitation settings.

Fitness Assessment and Testing: Importance

• Assessing fitness before exercise helps tailor activities to individual capabilities and prevent injury.
• Age, health status, lifestyle choices, and physical limitations affect fitness.
• Body composition measurement, vital signs, and fitness tests are common assessment methods.

Methods of Fitness Testing

• Stress Electrocardiogram (ECG) monitors heart activity during exercise for potential cardiac issues.
• Ambulatory Electrocardiogram is a 24-hour test to assess heart function during daily activities, especially for patients with prior cardiac symptoms.
• Submaximal Fitness Tests like the step and walk-a-mile tests estimate fitness levels without exhaustion.

Vital Signs and Their Significance

• Vital signs indicate health status and response to exercise.
• Elevated vital signs during rest may indicate underlying health issues complicating exercise programs.
• Monitoring vital signs ensures safety and effectiveness.

Exercise Guidelines for Older Adults

• Balance physical activity with rest to avoid overexertion if the patient has health issues or disabilities.
• Hydration, with water preferred over caffeinated or alcoholic beverages, is crucial during exercise.
• Activities of exercise should be adapted to individual capabilities, done seated or lying down if needed.

Safety Precautions

• Footwear with nonskid soles prevent falls during exercise.
• Caregivers should assist older adults in range of motion exercises to prevent muscle atrophy and maintain joint function.

Cardiac Rehabilitation and Monitoring: Holter Monitor

• A Holter monitor is portable for evaluating heart response during cardiac rehabilitation and medical therapy.
• Chest leads connect to a belt, shoulder strap, or pocket for ambulatory ECG monitoring.
• During monitoring, patients must avoid water and electromagnetic fields to prevent artifacts.
• Patients should maintain a diary of activities, medication intake, and symptoms experienced.
• After the monitoring period, a physician compares diary entries with ECG results to assess heart muscle oxygenation and rhythm abnormalities.
• Findings may indicate a need to delay exercise or start at a low intensity, ensuring patient safety.

Step Test Overview

• The step test is a submaximal fitness assessment involving timed stepping on a platform, with variations like the Harvard, Queens College, and Chester Step Tests.
• Participants step up and down on a platform at a rate of at least 76 steps per minute for 3-5 minutes.
• The examiner uses a metronome and stopwatch to track the stepping rate and duration, stopping if the participant cannot maintain the pace or experiences discomfort.
• Recovery index = (100 x test duration in seconds) / (2 x total of the 30 seconds pulse assessments). is the formula for recovery index
• A smaller decline in heart rate post-test indicates better fitness levels, and the similarity between pretest and posttest pulse rates is a key fitness indicator.
• Certified personnel must be present during the test to manage any adverse cardiac events.

Walk-a-Mile Test

• The walk-a-mile test measures the time taken to walk 1 mile on a flat surface devised by the American College of Sports Medicine
• Participants are instructed to walk as fast as possible, with performance times recorded and interpreted against established guidelines.
• A brisk walking pace (3-4 mph) typically results in a completion time of about 30 minutes for 1-2 miles.
• The test provides insights into cardiovascular endurance and overall fitness levels, helping to tailor exercise prescriptions.
• Results can be compared with standardized fitness levels to assess individual performance.
• This test is simple and effective for evaluating cardiovascular fitness in various populations.

Activity Monitoring Tools

• Pedometers and wristband monitors, like Fitbits, track physical activity levels, measuring steps and distance walked.
• 10,000 steps daily is often recommended for maintaining health and fitness.
• Activity levels can be categorized based on step counts, ranging from sedentary to highly active.
• Monitoring helps individuals understand their activity patterns and encourages increased physical activity.
• These devices can provide feedback and motivation, aiding in the achievement of fitness goals.
• Regular monitoring can lead to improved health outcomes and increased awareness of physical activity levels.

Target Heart Rate Calculation

• Target heart rate is the desired heart rate during exercise.
• Subtract a person's age from 220 to find the maximum heart rate; for example, a 20-year-old has a maximum heart rate of 200 bpm, while a 50-year-old has 170 bpm.
• Moderate intensity exercise should aim for 64%-76% of the maximum heart rate, while beginners should not exceed 50%.
• Competitive athletes may tolerate 70%-85% of their maximum heart rate during vigorous activities.
• Exercising at the target heart rate for at least 15 minutes, three times a week, strengthens the heart and promotes fat utilization for energy.
• Exceeding the target heart rate can lead to increased fatigue and reduced endurance.

Metabolic Energy Equivalent (MET)

• MET measures energy expenditure and oxygen consumption during physical activities, guiding exercise prescriptions based on fitness levels.
• Different activities are categorized by their MET values, indicating the intensity of the exercise.
• Low-to-vigorous activities are prescribed according to the individual's cardiovascular capacity, ensuring safety during exercise.
• Understanding METs helps tailor exercise programs to meet individual fitness goals and capabilities.
• Activities with lower METs are suitable for beginners or those with health concerns, while higher MET activities are for more fit individuals.
• This classification aids in developing a structured and effective exercise regimen.
