NETA CPT cheat sheet

Scope of practice: a certified personal trainer designs and supervises exercise programs, conducts fitness assessments, and educates clients on lifestyle habits; it excludes diagnosis, prescription, and medical treatment.

PAR-Q+ screening logic: if a client answers yes to any follow-up question on the PAR-Q+, they need clearance from a qualified healthcare provider before beginning or progressing an exercise program.

FITT-VP principle: Frequency, Intensity, Time, Type, Volume, and Progression form the standard framework for structuring aerobic, resistance, and flexibility prescriptions.

ACSM aerobic guideline for healthy adults: at least 150 minutes per week of moderate-intensity or 75 minutes per week of vigorous-intensity cardiorespiratory exercise, or an equivalent combination.

Resistance training guideline: 2 or more days per week targeting all major muscle groups, generally 2 to 4 sets of 8 to 12 repetitions at 60 to 70 percent of 1RM for general fitness.

Flexibility guideline: static stretching of major muscle-tendon units at least 2 to 3 days per week, holding each stretch 10 to 30 seconds and accumulating about 60 seconds per muscle group.

Heart rate maximum estimate: 220 minus age; moderate intensity is approximately 64 to 76 percent of HRmax and vigorous intensity is approximately 77 to 93 percent of HRmax.

Karvonen method: target heart rate equals ((HRmax minus resting HR) times intensity percentage) plus resting HR, which accounts for individual resting heart rate.

Progressive overload requires increasing load, volume, or frequency gradually; general guidance is to raise training variables by no more than about 5 to 10 percent per week to limit injury risk.

Muscle contraction types: isotonic (concentric shortening or eccentric lengthening with joint movement), isometric (tension without joint movement), and isokinetic (constant angular velocity).

The sliding filament theory states that actin and myosin cross-bridges cycle and shorten sarcomeres during contraction; calcium binding to troponin exposes actin binding sites.

Muscle fiber types: Type I fibers are slow-twitch, oxidative, and fatigue-resistant; Type IIx fibers are fast-twitch, glycolytic, and fatigue quickly but produce high force.

Sagittal plane movements include flexion and extension; frontal plane movements include abduction and adduction; transverse plane movements include rotation and horizontal adduction.

Prime mover, antagonist, synergist, and stabilizer roles describe how muscles cooperate during a movement; for example, the biceps brachii is the prime mover in elbow flexion and the triceps brachii is the antagonist.

The length-tension relationship holds that a muscle generates maximal active force at an optimal resting length, with force declining when over-shortened or over-lengthened.

The force-velocity relationship holds that concentric force decreases as shortening velocity increases, while eccentric contractions can produce greater force than isometric or concentric actions.

Levers: a first-class lever has the fulcrum between load and effort, a second-class lever has the load between fulcrum and effort, and a third-class lever has the effort between fulcrum and load; most human joints act as third-class levers.

The stretch-shortening cycle combines an eccentric phase, an amortization phase, and a concentric phase; a shorter amortization phase improves power output in plyometric actions.

Phosphagen (ATP-CP) system supplies energy for approximately the first 10 seconds of maximal effort and requires no oxygen; it powers sprints and heavy single lifts.

Anaerobic glycolysis dominates from roughly 10 seconds to 2 minutes of intense effort and produces lactate plus hydrogen ions, contributing to fatigue in high-intensity work.

Oxidative phosphorylation is the primary energy source for sustained activity beyond about 2 minutes and occurs in the mitochondria using carbohydrates and fats with oxygen.

The lactate threshold is the intensity at which blood lactate begins to accumulate faster than it is cleared; training at or near this intensity improves endurance performance.

VO2max is the maximal rate of oxygen uptake and is expressed in milliliters of oxygen per kilogram of body weight per minute; it is a key marker of cardiorespiratory fitness.

EPOC (excess post-exercise oxygen consumption) is elevated oxygen uptake after exercise that supports replenishment of phosphagens, lactate clearance, and temperature normalization.

Acute responses to aerobic exercise include increased heart rate, stroke volume, cardiac output, and ventilation, with blood flow redistributed from viscera to working muscle.

Chronic adaptations to aerobic training include increased stroke volume, capillarization, mitochondrial density, and plasma volume, which lower resting and submaximal heart rate.

Chronic adaptations to resistance training include muscle hypertrophy, increased motor unit recruitment, and improved neural coordination, with strength gains often preceding measurable size gains.

The five health-related components of fitness are cardiorespiratory endurance, muscular strength, muscular endurance, flexibility, and body composition; skill-related components include power, speed, agility, balance, coordination, and reaction time.

Body mass index equals weight in kilograms divided by height in meters squared; it does not distinguish fat from lean mass and should be interpreted alongside other measures.

The ACSM push-up and plank tests assess muscular endurance; the sit-and-reach test assesses hamstring and low-back flexibility; the 1.5-mile run or 12-minute run assesses cardiorespiratory fitness.

The 1RM test measures maximal strength directly; a repetition-max prediction (such as the Brzycki formula) estimates 1RM from a submaximal set to reduce injury risk.

The Borg RPE scale runs from 6 to 20, with 12 to 13 corresponding to moderate intensity and 14 to 17 to vigorous intensity; the 0 to 10 CR10 scale is an alternative.

Periodization organizes training into macrocycles, mesocycles, and microcycles, varying volume and intensity over time to optimize adaptation and prevent overtraining.

The OPT model progresses through stabilization endurance, strength endurance, hypertrophy, maximal strength, and power phases, each with distinct sets, repetitions, and tempos.

Training volume is commonly calculated as sets multiplied by repetitions multiplied by load; volume and intensity are inversely related in most program design schemes.

Overtraining signs include persistent fatigue, performance decline, elevated resting heart rate, disturbed sleep, and mood changes; these require reduced training load and recovery.

Energy balance: weight gain occurs with a sustained caloric surplus and weight loss with a sustained deficit; approximately 3,500 kilocalories corresponds to about 0.45 kilograms (1 pound) of fat tissue.

Macronutrient energy values: carbohydrate and protein each provide about 4 kilocalories per gram, fat provides about 9 kilocalories per gram, and alcohol provides about 7 kilocalories per gram.

The Acceptable Macronutrient Distribution Range is 45 to 65 percent of calories from carbohydrate, 20 to 35 percent from fat, and 10 to 35 percent from protein for adults.

General protein guidance for active adults is approximately 1.2 to 2.0 grams per kilogram of body weight per day, with higher intakes during caloric restriction or heavy resistance training.

A safe rate of weight loss is generally 0.5 to 1 percent of body weight per week, which helps preserve lean mass and supports adherence.

Hydration: drink roughly 5 to 7 milliliters per kilogram of body weight about 4 hours before exercise, and replace fluid losses during activity; a 2 percent body mass loss from sweat can impair performance.

A personal trainer may provide general nutrition education but must refer clients to a registered dietitian for individualized meal plans and medical nutrition therapy where scope-of-practice rules require it.

Resting metabolic rate typically accounts for 60 to 75 percent of total daily energy expenditure; physical activity and the thermic effect of food make up the remainder.

Absolute contraindications to exercise testing include acute myocardial infarction, unstable angina, uncontrolled arrhythmias, and acute heart failure; testing must be deferred.

Relative contraindications include uncontrolled hypertension, tachyarrhythmias, and moderate stenotic valvular disease; these require clinical judgment before testing.

Blood pressure classification: normal is below 120/80 mmHg, elevated is 120 to 129 systolic with diastolic below 80, and stage 1 hypertension is 130 to 139 over 80 to 89 mmHg.

Informed consent must be obtained before assessment or training and should disclose purpose, risks, benefits, and the client's right to withdraw at any time.

Emergency action plan elements include venue address, emergency contacts, location of an AED, designated responder roles, and documented practice drills.

Signs requiring immediate exercise cessation include chest pain, severe shortness of breath, dizziness, syncope, and pale or cold skin; summon emergency services if symptoms persist.

Negligence requires four elements: duty of care, breach of that duty, causation, and damages; accurate records and clear scope-of-practice boundaries reduce liability exposure.

Confidentiality obligations require protecting client health information and obtaining written authorization before sharing records with third parties.

During pregnancy, avoid supine exercise after the first trimester, avoid contact sports and activities with fall risk, and follow the PARmed-X for Pregnancy clearance process.

Older adults should include balance and fall-prevention training at least 2 to 3 days per week alongside aerobic and resistance work; the Otago program is a validated example.

Youth resistance training is safe with qualified supervision, focusing on technique and light loads; the NSCA recommends beginning with 1 to 2 sets of 8 to 15 repetitions.

Clients with type 2 diabetes should monitor blood glucose around exercise, carry fast-acting carbohydrate, and inspect feet for injury; exercise is generally avoided during active foot ulcers.

Clients with hypertension should avoid heavy Valsalva maneuvers and high-intensity isometric work; aerobic exercise and moderate resistance training are generally preferred.

For clients with obesity, choose low-impact modalities such as cycling, swimming, and walking to reduce joint stress, and progress volume gradually to support adherence.

Clients with osteoporosis should emphasize weight-bearing and resistance exercise while avoiding high-impact loading and spinal flexion under load, depending on fracture risk.

Clients with cardiovascular disease require physician clearance and should follow prescribed intensity ranges; monitor for angina equivalents and unusual dyspnea during sessions.

The transtheoretical model stages are precontemplation, contemplation, preparation, action, and maintenance; interventions should match the client's current stage.

Self-efficacy, the belief in one's capability to perform a behavior, predicts exercise adherence; mastery experiences and vicarious experience are key sources.

SMART goals are specific, measurable, attainable, relevant, and time-bound; process goals (such as attending 3 sessions weekly) often support adherence better than outcome goals alone.

The health belief model holds that behavior change depends on perceived susceptibility, severity, benefits, barriers, and cues to action.

Self-determination theory identifies autonomy, competence, and relatedness as basic psychological needs; supporting these needs improves intrinsic motivation.

Motivational interviewing uses open-ended questions, affirmations, reflective listening, and summaries (OARS) while rolling with resistance rather than confronting it.

The stages of learning a motor skill are cognitive, associative, and autonomous; feedback should shift from frequent and explicit to intermittent and internal as skill develops.

Behavioral strategies with evidence for adherence include self-monitoring, action planning, social support, and relapse-prevention planning for lapses.
