Bioelectrical impedance analysis

22

Use of ionizing radiation by an x-ray beam to create images of body segments

Computed Tomography

23

True or false?
Even though the gold standard for measuring body composition are hydrostatic weighing and DEXA, most acceptable assessment for athletes and field conditions is skinfold measurements analysis

True

24

Which of the following statements regarding the relationship between body composition and sport performance is incorrect?
