ACSM CEP key terms

Structured review of current exercise habits, symptoms, and medical history used to decide whether a person needs medical clearance before starting exercise or increasing intensity.

Classifying patients by likelihood of a cardiac event during exercise using disease severity, symptoms, and test results, which guides the level of monitoring and supervision required.

A clinical condition, such as unstable angina, acute myocarditis, or severe aortic stenosis, in which exercise testing or training must be postponed until the condition is treated or resolves.

A condition in which exercise testing carries added risk but may proceed if the patient is stable and the information gained is judged worth the risk.

Symptoms such as shortness of breath, jaw or arm discomfort, or indigestion that signal myocardial ischemia without classic chest pain; they count as positive symptoms during screening and testing.

A unit expressing the energy cost of an activity as a multiple of resting oxygen consumption, with 1 MET equal to about 3.5 mL of oxygen per kilogram per minute.

The highest workload or oxygen uptake a person can sustain, usually reported in METs; it reflects cardiorespiratory fitness and strongly predicts prognosis in cardiac patients.

An impaired rise in heart rate during graded exercise, commonly defined as failure to use at least 80 percent of predicted heart rate reserve; it limits exercise capacity and worsens prognosis.

Heart rate multiplied by systolic blood pressure, an indirect estimate of myocardial oxygen demand used to judge effort and to identify the point where ischemia begins.

A downward shift of the ST segment on the ECG during stress; horizontal or downsloping depression of at least 1 mm suggests subendocardial ischemia.

Inadequate myocardial blood flow during exertion, detected by ECG changes, symptoms, or imaging abnormalities that appear with stress and resolve with rest.

The ratio of carbon dioxide produced to oxygen consumed; values of about 1.10 or higher suggest near-maximal effort during a graded exercise test.

The highest oxygen uptake measured during a symptom-limited exercise test, used when a true plateau is not achieved, as is common in patients with chronic disease.

The point at which oxygen uptake stops rising despite further increases in workload, representing maximal aerobic capacity; it is rarely attained in clinical populations.

The difference between maximal and resting heart rate; it is used to set training intensities and to evaluate how normally heart rate responds to exercise.

Calculating target heart rate as resting heart rate plus a chosen percentage of heart rate reserve, which accounts for individual resting values better than a percent-of-maximum approach.

A submaximal field test that measures how far a person walks in six minutes, used to estimate functional capacity and track change in cardiac or pulmonary rehabilitation.

The exercise intensity at which ventilation begins to rise disproportionately to oxygen uptake, marking increased anaerobic contribution and often used to set training zones.

A prescription framework covering frequency, intensity, time, type, volume, and progression, ensuring that every component of an exercise plan is explicitly defined.

The heart rate range chosen to keep exercise at a desired intensity, usually calculated from a percentage of maximal heart rate or of heart rate reserve.

A subjective effort score, commonly from Borg's 6-20 or 0-10 scale, used to regulate intensity when heart rate is unreliable, such as with beta-blockers or atrial fibrillation.

The heaviest resistance a person can lift once with correct technique; it anchors resistance-training loads, which are usually prescribed as a percentage of this value.

The heart rate or workload at which ischemia first appears during exercise testing; training intensity is generally kept below this point for safety.

A period of light activity before conditioning that raises muscle temperature and blood flow and prepares the cardiovascular system for more intense work.

Gradual tapering of activity after the conditioning phase that prevents blood pooling, sudden blood pressure drops, and arrhythmias, particularly in patients taking vasodilating medications.

A written and rehearsed protocol that assigns roles, locates equipment, and outlines response steps for cardiac arrest or other emergencies during exercise sessions.

A portable device that analyzes the heart rhythm and delivers a shock for shockable cardiac arrest; rapid access and use are central to exercise facility safety.

The process of explaining purpose, risks, benefits, and alternatives so a participant freely agrees to testing or training, documented by a signed form.

The legal and professional boundaries of what a clinical exercise physiologist may do, set by education, certification, state law, and employer policy.

A behavior change framework describing stages from precontemplation through maintenance, with counseling strategies matched to the stage a person is currently in.

A person's belief in their ability to carry out a specific behavior, such as exercising regularly; stronger confidence predicts better initiation and adherence.

A collaborative counseling style using open questions, reflections, and affirmations to help clients articulate and strengthen their own reasons for changing behavior.

Objectives that are specific, measurable, achievable, relevant, and time-bound, turning vague intentions into concrete targets that can be tracked and adjusted.

Planning ahead for lapses by identifying triggers, building social support, and reframing setbacks as temporary so that exercise habits persist over time.

Cramping leg pain provoked by walking and relieved by rest, caused by peripheral arterial disease; structured walking programs can increase pain-free walking distance.

A U.S. law governing the privacy and security of identifiable health information, shaping how exercise professionals store, share, and discuss patient data.

The amount of monitoring a patient receives during training, from continuous ECG to intermittent checks or none, chosen according to risk category and clinical stability.
