Medical Clearance — When to Seek It

Medical clearance means approval from a qualified healthcare professional to engage in exercise — possibly with parameters (e.g., intensity limits, medication adjustments, supervised setting). In current ACSM practice it is requested for a targeted minority, not routinely for everyone.

Seek medical clearance when:

• Any sign/symptom suggestive of CMR disease is present (see signs-symptoms-cvd) — strongest indication.
• The ACSM algorithm flags clearance based on disease status, inactivity, and desired intensity (e.g., inactive person with known CMR disease wanting moderate/vigorous exercise; inactive person with no disease wanting vigorous).
• A PAR-Q+ follow-up question is answered "yes."
• The person is returning from injury, surgery, or pregnancy, or has an unstable/poorly controlled condition (uncontrolled hypertension, recent cardiac event, decompensated diabetes).

What it is not: A blanket requirement for healthy adults to visit a doctor before walking or starting light activity. Over-referral was the problem the modern screening approach was designed to fix.

Practical note for fitness professionals: When clearance is indicated, document the recommendation, provide the client a referral note, and resume programming only after written/verbal clearance is obtained. Absence of clearance when indicated is a liability and safety risk.

• Clearance = provider approval to exercise, sometimes conditional.
• Triggered by signs/symptoms, the ACSM algorithm, a PAR-Q+ "yes," or return-from-injury/unstable conditions.
• Targeted, not universal — routine clearance for healthy adults is discouraged.
• Fitness pros should document the referral and wait for clearance before proceeding.

• acsm-screening-algorithm / par-q-plus — the tools that flag the need.
• signs-symptoms-cvd — the strongest trigger.
• return-from-injury — a common clearance scenario.
