NSCA-CPT key terms

A brief screening form that asks about symptoms and medical conditions to identify people who should consult a physician before starting or increasing exercise. A positive answer generally requires medical clearance before training.

The process of explaining the purpose, procedures, risks, benefits, and alternatives of an assessment or program, then obtaining the client's voluntary written agreement to take part. It documents shared decision-making and supports risk management.

A form completed before exercise participation that collects past and current medical conditions, medications, surgeries, injuries, family history, and lifestyle habits so the trainer can design a safe program.

The process of classifying clients by their likelihood of a cardiac event during exercise, using symptoms, known disease, and risk factors, so appropriate medical clearance and supervision levels can be set.

A ratio of body weight in kilograms to height in meters squared (kg/m2) used to screen for underweight, overweight, and obesity. It does not distinguish fat mass from lean mass.

Waist circumference divided by hip circumference; a simple index of fat distribution in which higher values suggest greater abdominal fat and higher cardiometabolic risk.

A technique using calipers to pinch and measure subcutaneous fat at specific body sites; the site values are summed and entered into equations to estimate body fat percentage.

A method that passes a low-level electrical current through the body to estimate body composition, based on the principle that fat resists current more than water-rich lean tissue does.

A test in which the client exercises below maximum effort while heart rate, blood pressure, and symptoms are monitored; results are used to estimate aerobic capacity and to set training intensities.

The heaviest resistance a client can lift once with correct technique. It is the standard direct measure of muscular strength and is used to set loads as percentages of maximum.

A field test of hamstring and low-back flexibility in which the client sits with legs extended and reaches forward as far as possible along a measured box or ruler.

Categorizing a resting reading as normal, elevated, stage 1, or stage 2 hypertension based on systolic and diastolic values, which determines whether exercise proceeds, is modified, or needs medical clearance.

The number of heartbeats per minute measured after at least five minutes of quiet rest; it is used with maximal heart rate to calculate individualized training heart rate ranges.

A framework for designing programs that specifies Frequency, Intensity, Time, Type, Volume, and Progression of exercise so training meets the client's goals safely and can be adjusted over time.

Systematically increasing the demand placed on the body through load, volume, or intensity so adaptation continues; increases should be small and applied only when the client tolerates the current workload.

The concept that the body adapts specifically to the stress imposed, so training must mimic the movement patterns, energy systems, and intensities of the desired outcome. SAID stands for Specific Adaptation to Imposed Demands.

The principle that fitness gains are lost when training stops or the stimulus is reduced; detraining begins within a few weeks, so programs should be adjusted during breaks to retain as much as possible.

Planned, organized variation of training variables over time, often in cycles, to peak for goals, avoid plateaus, and reduce overtraining risk while maintaining long-term progress.

A method for setting target heart rate: (maximal heart rate minus resting heart rate) multiplied by the desired intensity percentage, then added to resting heart rate. It accounts for individual resting heart rate.

A brief period of low-intensity activity and dynamic movements before the main session that raises body temperature, increases blood flow, and prepares joints and muscles for the work to follow.

A gradual reduction in exercise intensity, often using low-level aerobic activity and static stretching, after the main session to help heart rate and blood pressure return toward resting values.

An informal intensity-monitoring method in which the client's ability to speak in full sentences indicates moderate intensity, while speaking only a few words indicates vigorous intensity.

A subjective scale, commonly 6 to 20, on which clients rate how hard they feel they are working; ratings are used to monitor and adjust intensity when heart rate is unreliable or unavailable.

Forcefully exhaling against a closed glottis, which sharply raises intrathoracic pressure and blood pressure. Clients with cardiovascular risk should generally avoid it and breathe continuously during lifts.

The trained assistant's role during resistance exercise of positioning to help control or lift the load if the client fails, while also cueing technique; it requires an agreed signal and full attention.

A muscle action in which tension is produced while the muscle shortens, as when lifting a weight against gravity during the upward phase of a curl.

A muscle action in which tension is produced while the muscle lengthens under load, as when lowering a weight; it allows control of heavier loads and typically causes more muscle soreness.

A muscle action in which tension is generated without a change in joint angle or muscle length, such as holding a plank or pushing against an immovable object.

A position in which the natural curves of the cervical, thoracic, and lumbar spine are maintained and the pelvis is balanced; it is the preferred alignment for many lifts to reduce injury risk.

The arc through which a joint moves, usually measured in degrees; resistance training through a full, pain-free range supports strength and flexibility, while partial repetitions are used selectively.

A movement in which the distal segment (hand or foot) is fixed against a surface, as in a squat or push-up, so multiple joints move together and stability is emphasized.

A movement in which the distal segment is free to move in space, as in a leg extension or biceps curl, isolating a muscle group and often used for targeted strengthening.

Failure to provide the care a reasonably prudent professional would provide in similar circumstances, resulting in harm. A claim requires duty, breach of duty, causation, and damages.

The degree of care and skill a reasonably competent fitness professional with similar training would exercise in the same situation; it is the benchmark used to judge conduct in legal claims.

The boundaries of what a certified personal trainer is legally and ethically trained and permitted to do, such as designing exercise programs but not diagnosing injuries or prescribing diets.

A written, rehearsed procedure specifying roles, emergency contacts, equipment locations, and response steps for medical emergencies such as cardiac arrest, choking, or severe injury in the facility.

A portable device that analyzes a heart rhythm and delivers a shock to a person in cardiac arrest; it should be applied as soon as available while cardiopulmonary resuscitation continues.

A first-aid approach for acute soft-tissue injuries aimed at limiting swelling and pain; ice is applied for short periods with a barrier, and the client is referred for further evaluation.

A heat illness marked by heavy sweating, weakness, dizziness, nausea, and cool clammy skin; the client should be moved to a cool place, given fluids, and monitored closely, with emergency care if symptoms worsen.

An infection-control practice of treating all blood and body fluids as potentially infectious, using gloves and other barriers and proper cleanup, to prevent transmission of viruses such as hepatitis and HIV.
