Physical Activity and Cancer

Physical Activity and Cancer:

Physical activity plays a crucial role in cancer prevention, treatment, and overall well-being. It is essential for individuals diagnosed with cancer to understand the impact of physical activity on their health and to incorporate appropriate levels of exercise into their daily routines. In this course, we will explore key terms and vocabulary related to physical activity and cancer to help health coaches effectively support cancer patients in their journey towards improved health and well-being.

Cancer:

Cancer is a complex group of diseases characterized by the uncontrolled growth and spread of abnormal cells. It can affect any part of the body and is a leading cause of death worldwide. There are over 100 different types of cancer, each with its unique characteristics and treatment options. Common types of cancer include breast cancer, lung cancer, prostate cancer, and colorectal cancer.

Example: A person diagnosed with breast cancer may undergo surgery, chemotherapy, radiation therapy, or a combination of treatments to manage their condition.

Physical Activity:

Physical activity refers to any bodily movement produced by skeletal muscles that requires energy expenditure. It includes activities such as walking, running, swimming, cycling, and strength training. Regular physical activity is essential for maintaining good health and reducing the risk of chronic diseases, including cancer. The American Cancer Society recommends at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity exercise per week for cancer prevention.

Example: A cancer patient may engage in regular physical activity such as brisk walking, yoga, or swimming to improve their physical and mental well-being during treatment.

Exercise:

Exercise is a subset of physical activity that is planned, structured, and repetitive. It is usually performed with the goal of improving or maintaining physical fitness, health, and overall well-being. Examples of exercise include jogging, weightlifting, yoga, and aerobic classes. Exercise has been shown to have numerous health benefits, including reducing the risk of cancer recurrence and improving quality of life in cancer survivors.

Example: A cancer survivor may participate in a structured exercise program to improve their cardiovascular fitness and muscle strength after completing treatment.

Cardiorespiratory Fitness:

Cardiorespiratory fitness is a measure of the ability of the heart, lungs, and muscles to work together efficiently during prolonged periods of physical activity. It is an essential component of overall fitness and is often assessed using measures such as VO2 max, which is the maximum amount of oxygen a person can utilize during intense exercise. Maintaining or improving cardiorespiratory fitness through regular exercise is important for cancer patients to enhance their endurance and overall health.

Example: A cancer patient undergoing chemotherapy may experience a decline in cardiorespiratory fitness, but with regular exercise, they can improve their endurance and energy levels.

Muscle Strength:

Muscle strength refers to the ability of a muscle or group of muscles to exert force against resistance. It is important for performing daily activities, maintaining good posture, and preventing injuries. Strength training exercises, such as weightlifting, resistance bands, and bodyweight exercises, can help cancer patients improve their muscle strength, bone density, and overall physical function.

Example: A cancer survivor may incorporate strength training exercises into their workout routine to build muscle mass and improve their physical strength after treatment.

Flexibility:

Flexibility is the range of motion of a joint or group of joints. Having good flexibility is important for performing everyday activities, preventing injuries, and maintaining proper posture. Stretching exercises, yoga, and Pilates are effective ways to improve flexibility and mobility in cancer patients. Regular stretching can also help reduce muscle tension and improve circulation.

Example: A cancer patient experiencing joint stiffness as a side effect of treatment may benefit from incorporating gentle stretching exercises into their daily routine to improve flexibility and reduce discomfort.

Balance:

Balance refers to the ability to maintain control of the body's position while standing, walking, or performing other activities. Good balance is essential for preventing falls, especially in older adults and cancer patients who may experience weakness or fatigue. Balance exercises, such as standing on one leg, heel-to-toe walking, and yoga poses, can help improve stability and reduce the risk of falls in cancer patients undergoing treatment.

Example: A cancer patient receiving chemotherapy may experience dizziness or weakness, making it important to include balance exercises in their exercise program to improve their stability and reduce the risk of falls.

Physical Activity Guidelines:

Physical activity guidelines provide recommendations on the type, duration, frequency, and intensity of exercise needed to improve health and well-being. These guidelines are based on scientific evidence and are designed to help individuals maintain or improve their physical fitness while reducing the risk of chronic diseases such as cancer. Health coaches play a crucial role in educating cancer patients about the importance of following physical activity guidelines and tailoring exercise programs to meet their individual needs and abilities.

Example: The Physical Activity Guidelines for Americans recommend at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity per week, along with muscle-strengthening activities on two or more days a week.

Barriers to Physical Activity:

Barriers to physical activity refer to factors that hinder or prevent individuals from engaging in regular exercise. These barriers can be physical, psychological, social, or environmental in nature and may include lack of time, motivation, resources, or social support. Cancer patients may face unique challenges that make it difficult for them to participate in physical activity, such as fatigue, pain, treatment side effects, or fear of injury. Health coaches can help cancer patients identify and overcome these barriers to physical activity by providing support, guidance, and resources to help them stay active and healthy.

Example: A cancer patient experiencing fatigue from chemotherapy may find it challenging to engage in regular exercise, but with the help of a health coach, they can develop a personalized exercise plan that takes into account their energy levels and limitations.

Exercise Prescription:

An exercise prescription is a specific plan or recommendation for physical activity tailored to an individual's needs, goals, and health status. It includes details such as the type of exercise, duration, frequency, intensity, and progression of the workout. Exercise prescriptions are commonly used by healthcare professionals, including health coaches, to help cancer patients safely and effectively incorporate physical activity into their daily routine. By following an exercise prescription, cancer patients can improve their fitness, manage treatment side effects, and enhance their quality of life.

Example: A health coach may prescribe a cancer patient with a combination of aerobic exercise, strength training, and flexibility exercises to help them improve their overall physical fitness and well-being.

Exercise Safety:

Exercise safety refers to the precautions and guidelines that should be followed to ensure that physical activity is performed in a safe and effective manner. For cancer patients, it is important to consider their health status, treatment side effects, and physical limitations when designing an exercise program. Health coaches should educate cancer patients on proper exercise techniques, warm-up and cool-down routines, hydration, and listening to their bodies to prevent injuries and promote a positive exercise experience.

Example: A cancer survivor with lymphedema may need to avoid heavy lifting or repetitive arm movements to prevent swelling and discomfort in the affected limb during exercise. The health coach can provide guidance on safe and appropriate exercises to minimize the risk of exacerbating lymphedema symptoms.

Adherence to Exercise:

Adherence to exercise refers to the extent to which an individual follows a prescribed exercise program over time. It is essential for cancer patients to adhere to their exercise regimen to maximize the benefits of physical activity and improve their overall health outcomes. Factors that influence adherence to exercise include motivation, social support, enjoyment, perceived benefits, and barriers to physical activity. Health coaches can help cancer patients overcome obstacles to exercise adherence by setting realistic goals, providing encouragement, and monitoring progress to help them stay on track with their fitness goals.

Example: A cancer patient who enjoys walking may be more likely to adhere to a daily walking routine than someone who dislikes running. By incorporating activities that the patient enjoys and finds rewarding, the health coach can help enhance exercise adherence and long-term success.

Exercise Progression:

Exercise progression involves gradually increasing the intensity, duration, or frequency of physical activity over time to challenge the body and achieve fitness goals. Progression is important for preventing plateaus in fitness, improving performance, and avoiding injuries. Cancer patients should work with their health coach to develop a progressive exercise plan that starts at a comfortable level and gradually increases in difficulty as their fitness improves. By incorporating proper progression into their exercise routine, cancer patients can continue to see improvements in their physical fitness and overall well-being.

Example: A cancer survivor who has been walking for 30 minutes a day may gradually increase their walking time by 5 minutes each week to build endurance and cardiovascular fitness. The health coach can help monitor progress and adjust the exercise plan accordingly to ensure safe and effective progression.

Physical Activity and Cancer Survivorship:

Physical activity plays a vital role in cancer survivorship by helping individuals manage treatment side effects, reduce the risk of cancer recurrence, and improve quality of life.
