Question

148. Which assessment allows a trainer to understand a client's lean body and total fat mass? A Body fat calculation B. Girth measurements C. Scale weight D. Photographs

Answer 1

148. The right choice is (A) Body Fat calculation

Calculation of total body fat helps in determining the lean body mass and total fat mass. Lean tissue is composed of metabolically active tissues that burn calories. These help in losing weight with exercise. If total body fat percentage is determined, the trainer can assess what kind of exercises and diet plan is to be followed to reduce body fat.

B- Girth measurements- Incorrect choice. Girth measurements give an estimate of body fat only in certain areas like waist, arms, thigh, etc. It does not help in understanding lean mass and fat mass.

C. Scale weight- Incorrect choice. The scale weight is a gross measurement of the weight of the entire body and it includes weight of bones, muscles, fat, internal organs, total body water and various types of tissues. It does not help in differentiating what proportion of the bodyweight is contributed by a particular type of tissue.

D. Photographs - Incorrect choice. Photographs do not help a trainer in assessing body fat composition. The angle of taking the picture, posture while taking the photograph, etc are difficult to standardize. Hence they tend to be inaccurate and misleading.
