Scope of Practice and Informed Consent for a Fitness Challenge
A certified exercise physiologist works at a commercial fitness center whose owner plans a 12-week 'transformation challenge.' The owner wants the exercise physiologist to run a testing day that includes a maximal treadmill test, body-fat measurement by bioelectrical impedance, and a 1,200-kcal diet plan, then to 'clear' participants for daily high-intensity interval training. A 61-year-old man signs up. He reports chest pressure two weeks ago while mowing the lawn that resolved with rest, but he has not seen a physician. He says, 'I will sign any waiver; I just need to lose 15 kg.' The owner says a waiver removes liability and cites a small online article claiming that short HIIT sessions are safe for everyone. The exercise physiologist's scope of practice includes exercise testing only with physician supervision for high-risk clients.
1. Identify the ethical and scope-of-practice issues in this request. Explain what the exercise physiologist should and should not agree to do.

The central issue is that the 61-year-old man has recent chest pressure, which is a high-risk symptom, and he has not been medically evaluated. A maximal treadmill test in this man is a diagnostic exercise test, not a routine fitness test. The exercise physiologist's scope permits exercise testing only with physician supervision for high-risk clients, so proceeding without that supervision would exceed scope and create serious safety risk.
The exercise physiologist should not 'clear' anyone for exercise, prescribe a 1,200-kcal diet without nutrition qualifications, or use a waiver as a substitute for screening and informed consent. A waiver does not eliminate the duty of care, and informed consent does not make an unsafe test acceptable. The owner's commercial pressure conflicts with professional obligations.
The exercise physiologist should agree to conduct appropriate preparticipation screening, measure body composition if within scope and with consent, and supervise exercise only after medical clearance. The high-risk man should be referred to a physician before any testing or vigorous exercise. The exercise physiologist should document the decision, communicate it in writing, and decline to run a maximal test on high-risk participants without medical supervision.
2. Apply preparticipation screening to the 61-year-old. What is his risk category, and what is the appropriate next step?

He has recent chest pressure during activity that resolved with rest. That is a symptom suggestive of cardiovascular disease, so he is high risk and should not begin a vigorous or maximal exercise program without medical evaluation. Age and the nature of the symptom reinforce the need for clearance. The fact that he wants to lose weight does not change the risk.
The appropriate next step is referral to a physician for evaluation, which may include a resting ECG, cardiovascular risk assessment, and possibly an exercise stress test. He should be advised to seek urgent care if the chest pressure recurs, lasts longer, occurs at rest, or is accompanied by sweating, nausea, or shortness of breath.
If his physician clears him with restrictions, the exercise physiologist can follow those restrictions. Until then, he should not participate in the challenge or the testing day. The waiver should not be accepted as a reason to proceed. The exercise physiologist should document the referral and provide a written summary of the screening decision.
3. The owner cites a small online article claiming HIIT is safe for everyone. How would you appraise this evidence and communicate your decision?
Read the worked answer
I would appraise the article by asking whether it is peer-reviewed, how many participants were studied, whether they were healthy or high-risk, what the actual outcomes were, and whether the conclusions were overstated. A small online article is not strong evidence for a blanket claim that HIIT is safe for everyone. Even if HIIT is safe in young, healthy, screened adults, that does not generalize to a 61-year-old with recent chest pain.
I would communicate the decision in writing: the challenge can proceed only with proper screening, medical clearance for high-risk participants, and an emergency action plan. I would not sign off on a protocol that includes maximal testing and daily HIIT for an unscreened high-risk man. I would offer an alternative low-to-moderate intensity program for cleared participants and refer the high-risk man to his physician.
If the owner insists on proceeding, I would escalate within the organization and follow the certification body's ethical guidelines. Documenting the conversation protects the exercise physiologist and the participants.
