The metabolic equivalent (MET) value of 1.0 represents:

Answer: Resting oxygen consumption of approximately 3.5 mL/kg/min

1 MET equals the resting metabolic rate, standardized at 3.5 mL O2/kg/min.

A client's DEXA scan reports a body fat of 32% with a body weight of 180 lbs. What is the client's fat-free mass?

Answer: 122.4 lbs

Fat mass = 32% × 180 = 57.6 lbs; fat-free mass = 180 − 57.6 = 122.4 lbs.

When using the ACSM leg press VO2 equation, which of the following represents the external work component?

Answer: Resistance (kgm/min) × 1.8 / body mass

For cycle ergometry, the VO2 equation uses resistance work component = (kgm/min × 1.8) / body mass in kg.

Which skinfold measurement site uses a DIAGONAL fold taken just below the inferior angle of the scapula?

Answer: Subscapular

The subscapular skinfold is taken at a 45-degree diagonal angle just below the inferior angle of the scapula.

A client has a resting HR of 60 bpm and a maximal HR of 185 bpm. Using the Karvonen method, what is the target HR for 70% intensity?

Answer: 147.5 bpm

HRR = 185 − 60 = 125; target HR = (125 × 0.70) + 60 = 87.5 + 60 = 147.5 bpm.

During a Bruce treadmill protocol, Stage 3 is completed at 3.4 mph and 14% grade. Using the ACSM running equation, what is the approximate VO2 at this stage?

Answer: 42 mL/kg/min

Stage 3 of the Bruce protocol (3.4 mph, 14% grade) corresponds to approximately 42 mL/kg/min using the ACSM running equation.

A client performs a maximal hand grip strength test. Results show 38 kg for the dominant hand. This measurement primarily assesses:

Answer: Muscular strength as an index of overall upper body strength

Grip strength is used as a practical indicator of overall upper body muscular strength and is correlated with functional capacity.
