ChatGPT-4o-Generated Exercise Plans for Patients with Type 2 Diabetes Mellitus—Assessment of Their Safety and Other Quality Criteria by Coaching Experts
Abstract
1. Introduction
- Are exercise plans generated by ChatGPT-4o safe for patients with T2DM?
- How do the safety and overall quality of ChatGPT-4o-generated exercise plans vary based on the quality of the prompts used?
2. Materials and Methods
2.1. Generating Exercise Plans Using ChatGPT-4o
2.2. Assessment of the Quality of ChatGPT-4o-Generated Exercise Plans
3. Results
3.1. Safety Issues
- The most common safety concern across all exercise plans was that users were not made aware of the need for a medical check-up prior to starting the training program, especially in cases of secondary conditions necessitating such a check-up (Patients 2 and 3) or when high-intensity workouts were recommended for sedentary patients [1].
- High-intensity training was recommended for Patient 3 with proliferative retinopathy. High-intensity training is not recommended for patients with proliferative retinopathy due to the risk of triggering vitreous hemorrhage or retinal detachment [1].
- It was not always mentioned that patients with (insulin-treated) diabetes should monitor their glucose levels before, during and after exercise to avoid hypoglycemia [16].
- It was not always mentioned that patients with high blood pressure should avoid holding their breath during strength exercises to prevent exorbitantly high and dangerous blood pressure peaks [16].
3.2. Other Training-Related Quality Criteria
- Training goals were not always closely aligned with SMART principles (specific, measurable, achievable, relevant, time-bound).
- Contrary to the ADA’s recommendations, no balance exercises were suggested for the older fictional patient (Patient 3).
- Missing details on the level of intensity, e.g., target training heart rate or whether to train to muscle failure during strength exercises or not.
- Many plans only included sample exercises, and it was sometimes unclear whether the user could or should add further exercises.
- The total training time did not match the proposed exercise volume.
- Many exercises seemed overwhelming, i.e., some complex bodyweight exercises seemed inappropriate for beginners.
