3.2 Medical Clearance, Contraindications, and Referrals

Key Takeaways

  • When the ACSM algorithm, a sign or symptom, or an unstable condition flags risk, the trainer delays exercise, documents the hold, and obtains medical clearance or an allied-health referral before training.
  • Absolute-style red flags such as unstable angina, decompensated heart failure, uncontrolled symptomatic arrhythmia, or acute infection mean stop and refer; relative findings still require clinician judgment before you proceed.
  • Request clearance with objective screening facts, current activity status, and intended intensity — never with a trainer-assigned diagnosis.
  • Physician, physical therapist, registered dietitian, and licensed mental-health referrals are scope decisions, not optional extras after you “try a few sessions.”
  • Virtual intake uses the same hold-and-refer rules as the gym floor; a video call does not authorize unscreened or symptomatic vigorous work.

3.2 Medical Clearance, Contraindications, and Referrals

When screening flags a problem, ACE Domain I Task 1 skill 4 is explicit: identify the need for and obtain medical clearance and referrals when appropriate. You are not deciding whether the client is “allowed to be healthy.” You are deciding whether you may start or continue exercise today, and which allied professional should see the person next. That decision is the same in a club, a park, a living room, or a video call.

When to Delay Exercise

Delay or stop in three situations:

  1. The ACSM algorithm recommends medical clearance — an inactive person with known cardiovascular, metabolic, or renal disease; anyone with signs or symptoms suggestive of those diseases; or an active person with known CMR disease who wants vigorous intensity.
  2. A temporary illness or unstable condition is present — fever, acute infection, a recent hospitalization, unexplained loss of consciousness, or blood glucose the client cannot stabilize.
  3. A contraindication to exercise testing or training is present or reasonably suspected.

“Delay” means you do not run a maximal test, a vigorous assessment, or a first session that stresses the suspected system. You can still complete paperwork, explain the process, and coach the client on how to obtain clearance. You cannot “modify around” chest pain, syncope, or a febrile infection.

Medical clearance is a healthcare professional’s approval to engage in exercise, with or without restrictions. The manner of clearance belongs to the clinician. ACSM is explicit that preparticipation screening is not the same thing as a periodic medical examination. You ask for the first when the algorithm or a red flag says you must. You still encourage the second as ordinary health care.

Absolute Versus Relative Contraindications — Conceptually

ACE does not publish a secret, ACE-only numbered list of contraindications you must memorize. Inventing one for the exam is a trap. Industry teaching, especially ACSM guidance on exercise testing, groups red flags as absolute or relative. Learn the logic and a few standard examples, not a fake ACE codebook.

Absolute contraindications are conditions in which the risk of continuing outweighs any fitness benefit until a physician stabilizes the problem. Classic ACSM-style examples include ongoing unstable angina, a recent acute myocardial infarction, decompensated heart failure, uncontrolled cardiac arrhythmias with hemodynamic compromise, acute myocarditis or pericarditis, acute pulmonary embolism or deep-vein thrombosis, acute aortic dissection, active endocarditis, and a physical disability that precludes safe testing. In the personal-training setting, treat acute systemic infection with fever and uncontrolled, symptomatic hypertension the same way: the trainer stops and refers. You do not bargain for a “light day.”

Relative contraindications are conditions in which exercise might proceed after a clinician weighs risk and benefit. ACSM testing literature has long listed examples such as resting hypertension with very high readings (systolic greater than 200 mm Hg or diastolic greater than 110 mm Hg as relative testing contraindications), known obstructive left-main coronary stenosis, moderate-to-severe aortic stenosis with uncertain symptoms, tachyarrhythmias with uncontrolled rates, recent stroke or transient ischemic attack, mental impairment that limits cooperation, and uncorrected anemia, important electrolyte imbalance, or hyperthyroidism. Relative does not mean the trainer may override it. It means the physician may allow activity with limits. Until that judgment exists, treat the finding as a hold.

You will not diagnose unstable angina on the gym floor. You will recognize the pattern: new or worsening chest pressure at rest or with less effort than before, pain that is not clearly musculoskeletal, and associated dyspnea, nausea, or sweating. That pattern is an emergency-level referral, not a programming puzzle.

FindingConceptual class (ACSM-style)Trainer action
Unstable angina; suspected acute coronary symptomsAbsolute-style stopStop; activate EAP or emergency services as indicated; do not train
Acute infection with fever; flu-like illnessDelay until resolvedDocument the hold; reschedule after recovery
Uncontrolled, symptomatic hypertension or a dangerous resting readingStop and referDo not start the session; send to the physician; recheck only after medical management
Resting BP in a very high range without acute symptomsRelative testing concernHold formal testing/training until a clinician weighs in
Stable, treated hypertension, no symptomsRisk factor, not a contraindication by itselfRun the ACSM algorithm; continue or start per that result
New unexplained syncope or exertional dizzinessSymptom suggestive of CMR diseaseStop; medical clearance before return

How to Request Clearance Without Diagnosing

Your job is to send facts, not a label. A useful written request includes:

  • Client identifiers and your role (ACE Certified Personal Trainer, not a diagnostic clinician).
  • Objective screening results: PAR-Q+ page-1 and follow-up answers, relevant health-history items, resting heart rate and blood pressure if you measured them, and any signs or symptoms described in the client’s words.
  • Current activity status (meets or does not meet the 30 minutes / 3 days / 3 months moderate standard).
  • The intended program: light, moderate, or vigorous aerobic work; resistance training; occupational or sport demands.
  • A clear ask: whether the client may participate, whether limits apply (heart-rate cap, avoid Valsalva or long isometrics, supervise only, medically supervised program), and whether further evaluation is advised.
  • A place for the clinician to sign, date, and state restrictions.

Never write “this client has unstable angina” or “please confirm my diagnosis of metabolic syndrome.” Never coach the client to hide symptoms to get a faster signature. Never accept a verbal “my doctor said it’s fine” without a dated, signed note when your algorithm said clearance is needed.

If the clinician returns a restricted clearance, honor the restrictions. If the clinician declines clearance, do not train the restricted components. If the note is vague (“cleared for exercise”), follow up once for intensity and mode. If you still cannot get detail, stay at the conservative end of what you originally requested and document that choice.

Document the Hold

A hold that is not written down did not happen for risk-management purposes. In the client record, note:

  • Date and time of the decision.
  • The specific finding that triggered the hold (quoted symptom, PAR-Q+ item, resting blood pressure, recent diagnosis).
  • What you did not do (no treadmill test, no first loaded session).
  • What you told the client, including that this is a safety pause, not a personal rejection.
  • Whom you referred to and how (physician, urgent care, emergency services).
  • Copies of letters sent and clearances received, with dates.
  • The date the hold was lifted and the conditions of return.

If symptoms suggest an acute coronary syndrome, stroke, or syncope, skip the polite letter and activate emergency medical services. Stay with the client, use the facility emergency action plan, and document after the person is in medical hands. The same sequence applies if a virtual client becomes pale, confused, or reports crushing chest pressure on camera: stay on the call, confirm the address, and have the client or a household member contact local emergency services.

Referrals Beyond the Physician

Clearance is one referral. Scope-of-practice referrals are the others. ACE Certified Personal Trainers collaborate; they do not impersonate other licenses.

Finding at intakeTypical referralWhy the trainer does not “just program it”
Signs or symptoms of CMR disease; new chest pain; unexplained syncopePhysician or emergency servicesDiagnosis and clearance are medical acts
Acute or worsening musculoskeletal injury, post-operative restrictions, unexplained radicular painPhysical therapist or sports-medicine physicianYou do not diagnose or rehabilitate injury
Disordered-eating flags, extreme restriction, requested meal plans, medical nutrition therapyRegistered dietitianPersonal trainers do not prescribe diets or treat eating disorders
Depression, anxiety, trauma, suicidal ideation, substance use that impairs safetyLicensed mental-health professional; emergency services if there is imminent riskCoaching is not psychotherapy
Pregnancy with complications, or a request for prenatal clearanceObstetric clinicianMedical judgment comes first; programming comes later
Uncontrolled diabetes, new neuropathy, non-healing woundsPhysician / diabetes care teamMedical stability before load and impact

Refer with respect. Say what you observed, what you will not do, and who can help. Offer to collaborate after the other professional sets boundaries. A client who wants you to “just give me a meal plan” or “adjust my blood-pressure pills around training” is asking you to leave scope. The professional answer is a referral, not a clever workaround.

Virtual Intake: Same Decision, Different Channel

A video or phone intake does not lower the bar. Send PAR-Q+ and the health-history form before the first live session. Review answers on camera, watch for dyspnea or pallor, and ask the same symptom questions. If a hold is required, you still stop, document, and request written clearance before the first loaded session. Do not supervise vigorous remote intervals for an unscreened or symptomatic client because “they are at home anyway.” Distance is not a clinical safeguard.

After clearance, re-screen when health status changes, when you plan a large jump in intensity, or when the PAR-Q+ year elapses. The file should show the original hold, the clinician’s note, and the date you lifted the restriction. That paper trail is how Domain I Task 1 looks in real practice — and how it is tested.
