During a 100 m time trial, which metrics should be recorded to evaluate sprint performance?

• A. Final time only
• B. Final time, splits (25/50/75), stroke rate, turn time, and perceived exertion
• C. Only heart rate at finish
• D. Number of kicks per length

Answer: (B)

In a sprint like a 100 m time trial, you learn how the race was executed by looking at a mix of speed, pacing, technique, and effort, not just the final clock time. Recording the final time shows the overall result, but the splits at 25, 50, and 75 reveal how quickly you accelerated, where you may have slowed, and how well you maintained speed across the race. Stroke rate tells you how fast your arms are moving and, together with efficiency (such as distance per stroke), helps explain why you covered the distance in that time. Turn time captures how efficiently you handle the wall and your push-off, which can make up a meaningful portion of the total time in a short sprint. Perceived exertion adds the swimmer’s own sense of effort, which informs pacing decisions and training load for future trials. Relying on only final time misses the pacing and technical elements, while focusing on one metric like heart rate at finish or number of kicks per length ignores the fuller picture of speed, turns, and effort.
