Final answer:
The FITT recommendation for individuals with cardiovascular disease in cardiac rehabilitation suggests a routine including low to moderate intensity aerobic exercises and muscle-strengthening activities, contributing to cardiovascular health and risk reduction.
Step-by-step explanation:
The FITT recommendation for individuals with cardiovascular disease participating in outpatient cardiac rehabilitation emphasizes a structured approach involving a combination of low to moderate intensity aerobic activities and muscle-strengthening exercises to improve overall cardiovascular health and manage the disease.
Individuals are generally encouraged to engage in at least 30 minutes of physical activity per day, which can be accrued through noncontinuous exercise, to reduce the risk of heart attack and other cardiovascular ailments. Moreover, adherence to a moderate exercise program, which may consist of approximately 1 hour per day, can yield substantial health benefits, including improved cardiovascular fitness and weight management. For those capable, an endurance program with 1-3 hours per day of moderate to high-intensity exercise can provide additional advantages.
According to the 2018 Physical Activity Guidelines by the U.S. Department of Health and Human Services, adults should aim for at least 150 to 300 minutes per week of moderate-intensity aerobic activity, or 75 to 150 minutes per week of vigorous-intensity aerobic physical activity, or a combination of both, preferably spread throughout the week. Muscle-strengthening activities are also recommended on 2 or more days per week.
