Which measurement procedure is best for increasing the time a swimmer can hold his breath underwater?

• A. Event recording
• B. Whole-interval recording
• C. Ratio recording
• D. Continuous recording

Answer: (B)

The best measurement procedure for increasing the time a swimmer can hold his breath underwater is whole-interval recording. This method is effective in assessing behaviors that occur over extended periods of time, such as breath-holding. In whole-interval recording, the observer notes whether the desired behavior (in this case, holding breath) occurs for the entire duration of specific intervals. This approach provides an accurate way to assess and reinforce improvements in duration since it focuses on whether the swimmer maintains breath-holding consistently throughout the intervals rather than just at a single point in time. Using this measurement technique allows for the collection of data that reflects the swimmer’s progress towards improving his breath-holding capability. This reinforces effective teaching practices by making it easy to visualize trends over time and notice incremental changes, which can inform coaching strategies and intervention adjustments to facilitate further improvement in the swimmer's breath-holding time. In contrast, other measurement strategies might not adequately capture the desired behavior's duration in a way that supports targeted development and emphasizes consistency over time.
