A student is collecting data about how lactate levels change during a 30-minute aerobic training session. Which data collection timeline would provide the most useful information?

  1. Measurement at 5-minute intervals during exercise and once during recovery
  2. Measurement before exercise and 30 minutes after completion
  3. Measurement only at the point of maximum perceived exertion
  4. Measurement once before exercise and once immediately after completion

Consider Option A: Measurement at 5-minute intervals during exercise and once during recovery

  • Taking measurements at regular intervals during exercise and recovery provides data on how lactate changes throughout the session and into recovery.

Other Options:

  • B is incorrect: Misses all changes during exercise and most of recovery.
  • C is incorrect: Single measurement provides minimal data about lactate changes over time.
  • D is incorrect: Only captures beginning and endpoint, missing lactate dynamics during exercise.
