Final answer:
According to the ACSM, the waist circumference threshold for men is greater than 40 inches and for women, it is greater than 35 inches for indicating obesity-related health risk(option a).
Step-by-step explanation:
ACSM Risk Factor for Obesity:
The ACSM (American College of Sports Medicine) identifies obesity as a risk factor for various chronic diseases. Specifically, the ACSM provides waist circumference thresholds as an indicator for this risk. For men, a waist circumference greater than 40 inches and for women, greater than 35 inches are considered as risk factors. This correlates with abdominal or central obesity, which is characterized by carrying excess weight around the waist (an “apple-shaped” body) as opposed to around the hips (“pear-shaped” body). The ACSM assessment is inline with the finding that central obesity is associated with a higher risk of chronic conditions like heart disease and type 2 diabetes compared to fat carried in other areas.
Therefore, the correct ACSM risk factor for obesity based on waist circumference is: A) Men: > 40 inches, Women: > 35 inches.
