An athletic trainer is assessing an athlete's body composition. Which method is considered the gold standard for body composition assessment?
Answer: DEXA (Dual-Energy X-ray Absorptiometry)
DEXA is considered the current gold standard for body composition assessment. It provides highly accurate measurements of fat mass, lean mass, and bone mineral density using low-dose X-ray technology.
During rehabilitation, progressive resistive exercise (PRE) follows the DAPRE (Daily Adjustable Progressive Resistive Exercise) protocol. What is the purpose of the third set in the DAPRE protocol?
Answer: Perform maximum repetitions at 100% of the working weight to determine adjustment
In the DAPRE protocol, the third set is performed at 100% of the working weight for maximum repetitions. The number of repetitions completed determines how the weight is adjusted for the fourth set.
Which factor has the greatest influence on the rate of tissue healing following a musculoskeletal injury?
Answer: Blood supply to the injured tissue
Blood supply is the single most important factor in tissue healing because it delivers oxygen, nutrients, growth factors, and immune cells necessary for the repair process. Tissues with poor vascularity (tendons, cartilage, ligaments) heal more slowly.
An athletic trainer is applying a cervical collar to an athlete with a suspected neck injury. Which size collar is appropriate?
Answer: A collar sized by measuring from the trapezius to the angle of the mandible
Cervical collar size is determined by measuring from the top of the trapezius (or shoulder) to the angle of the mandible. This measurement ensures the collar properly supports the cervical spine in a neutral position.
What is the primary neuromuscular mechanism by which proprioceptive neuromuscular facilitation (PNF) stretching achieves increased range of motion?
Answer: Autogenic inhibition via Golgi tendon organ activation
PNF stretching (contract-relax technique) works through autogenic inhibition: the isometric contraction activates the Golgi tendon organs, which inhibit the muscle spindle and alpha motor neurons, causing the muscle to relax and allowing greater stretch.
Which vital sign assessment finding would be most concerning in an athlete who has been exercising in hot, humid conditions?
Answer: Core body temperature of 104.5 degrees F (40.3 degrees C) with confusion
A core temperature above 104 degrees F (40 degrees C) combined with central nervous system dysfunction (confusion) meets the diagnostic criteria for exertional heat stroke, which is a medical emergency with potentially fatal consequences if not treated immediately.
