ACSM-EP certification, the healthy-client exam

When a client consistently mentions wanting to exercise but never follows through, which communication technique would be most effective?

1. Prescribing stricter scheduling
   Prescribing a stricter schedule answers a motivation problem with more rules. The client has not committed, so extra structure tends to raise resistance.
2. Direct confrontation
   Direct confrontation usually produces defensiveness and arguments for staying the same, the opposite of the change talk the trainer needs.
3. Highlighting discrepancy
   Highlighting the gap between what the client says they want and what they actually do lets the client voice their own reasons to change, the core move of motivational interviewing.
4. Ignoring the inconsistency
   Ignoring the inconsistency wastes the most useful material in the conversation and leaves the client's ambivalence unexplored.

When conducting a preparticipation health screening, which of the following client responses would indicate the need for medical clearance before beginning a moderate-intensity exercise program?

1. Being over 40 years old with no symptoms
   Age by itself no longer triggers clearance. The current algorithm looks at activity habits, known cardiovascular, metabolic or renal disease, and symptoms, so an asymptomatic person over 40 is not referred for age alone.
2. Having mild seasonal allergies
   Mild seasonal allergies are not a cardiovascular, metabolic or renal condition and do not call for clearance before moderate exercise.
3. Reporting occasional muscle soreness after activity
   Occasional soreness after activity is the normal response to unaccustomed exercise and is not a screening red flag.
4. Experiencing chest pain during physical exertion
   Chest pain with exertion is a sign suggestive of cardiovascular disease, so ACSM's screening algorithm calls for medical clearance before the program begins.

When calculating METs for a specific activity, which formula is MOST accurate?

1. METs = VO2 (mL/kg/min) ÷ 3.5
   One MET equals 3.5 mL/kg/min of oxygen uptake, so dividing relative VO2 by 3.5 gives the activity's cost in METs.
2. METs = VO2 (mL/kg/min) × 3.5
   Multiplying by 3.5 runs the conversion backwards: METs × 3.5 gives mL/kg/min, so this would inflate the answer more than tenfold.
3. METs = Heart rate ÷ resting heart rate
   A heart rate ratio is not a MET value; heart rate and oxygen cost do not scale one-to-one, and the ratio ignores the 3.5 mL/kg/min resting reference.
4. METs = VO2 (L/min) ÷ body weight (kg)
   Dividing absolute VO2 in L/min by body mass gives L/kg/min, a relative oxygen uptake in odd units, not a multiple of resting metabolism.

Which of the following statements about body composition assessment using bioelectrical impedance analysis (BIA) is correct?

1. It directly measures bone density
   BIA does not image bone. Bone mineral density needs a method such as DXA.
2. Hydration status can significantly affect measurement results
   BIA estimates body water from electrical impedance, so dehydration, recent fluid intake or a full bladder shift the result. That is why pre-test conditions are standardized.
3. Results are not affected by recent exercise
   Recent exercise changes fluid distribution and skin temperature, so it does affect BIA, which is why guidelines ask clients to avoid exercise before the test.
4. It provides the most accurate body composition measurements of all available methods
   BIA is a field estimate with a standard error of several percentage points; laboratory methods such as DXA or multi-compartment models are more accurate.
