Fat Burning Assessment and Evaluation 4

Question 1

What is the primary limitation of using BMI as an assessment tool for fat loss clients?

Accepted Answer

It does not distinguish between fat mass and muscle mass

Answer

BMI is calculated from height and weight and cannot differentiate between fat and lean (muscle) mass, making it misleading for muscular individuals.

Question 2

Which heart rate zone corresponds most closely to the 'fat-burning zone' during aerobic exercise?

Accepted Answer

50–65% of maximum heart rate

Answer

The fat-burning zone typically falls at 50–65% of maximum heart rate, where fat contributes a higher proportion of energy, though total caloric burn is lower than at higher intensities.

Question 3

A female client has a waist circumference of 36 inches. According to ACSM guidelines, this places her at:

Accepted Answer

High risk

Answer

ACSM and NIH classify a waist circumference greater than 35 inches (88 cm) in women as high risk for metabolic complications.

Question 4

Which formula is most commonly used to estimate maximal heart rate for exercise intensity assessments?

Accepted Answer

220 − age

Answer

The formula 220 minus age is the most widely used and recognized estimate of maximal heart rate, though the Tanaka formula (208 − 0.7 × age) may be more accurate.

Question 5

A 7-site skinfold test yields a body density of 1.0580 g/mL. Using the Siri equation, what is the estimated body fat percentage?

Accepted Answer

Approximately 16%

Answer

The Siri equation is % BF = (4.95 / body density − 4.50) × 100; plugging in 1.058 gives approximately (4.95/1.058 − 4.50) × 100 ≈ 16%.
