Final answer:
The most appropriate initial cardiorespiratory program for this client is walking 5-6 days per week for 10-20 minutes at an RPE of 11-13, with a goal to increase to 40-60 minutes, to safely increase physical activity and improve health outcomes as per evidence-based guidelines.
Step-by-step explanation:
The initial cardiorespiratory program that would be most appropriate for a new client with type 2 diabetes who has been sedentary is Option C: Walking 5-6 days per week for 10-20 minutes at an RPE (Rate of Perceived Exertion) of 11-13, working up to 40-60 minutes. This recommendation is aligned with evidence-based guidelines, suggesting that sedentary individuals start with low intensity or skill based activities and gradually increase duration and intensity. Since the client is sedentary, a progressive approach is important to avoid injury and to build her endurance over time. According to the 2018 Physical Activity Guidelines for Americans, adults should aim for at least 150 minutes of moderate-intensity aerobic activity per week, and it is suggested to spread this activity throughout the week. This plan meets these recommendations by starting at a manageable level and progressing toward more sustained physical activity, thereby helping with weight loss and blood glucose regulation.
