Question

an athletic trainer is working with college sprinters. he is interested in reducing the amount of time it takes for the runners to begin once the start gun has been fired. therefore, he measures the time from when the gun goes off to when the runner starts. he is measuring the: a latency of a response b frequency of a response c duration of a response d timing of a response

Explanation:

To solve this, we analyze each option:

• Option A: Latency of a response refers to the time between a stimulus (start gun) and the start of a response (runner starts). This matches the scenario.
• Option B: Frequency is about how often a response occurs, not time to start, so eliminate.
• Option C: Duration is the length of the response (e.g., how long the run takes), not the time to start, so eliminate.
• Option D: Timing usually refers to when in a cycle or sequence a response occurs, not the delay from a stimulus, so eliminate.

Answer:

A. latency of a response
