Swim Coaching Science: Swim 100 Meters in 40 Seconds (Ebook)

Description

“Swim 100 Meters in 40 Seconds” is an ebook in the Swim Coaching Science series.

In the preface to the Science of Swimming, Doc Counsilman (1968) suggested that a 40 second 100 meter freestyle was possible. When Doc made his prediction, the world record was about 54 seconds. Now the world record is about 7 seconds faster. Another 7 seconds is required to lower the record to 40 seconds. With the current trend (Figure P-1, regression line), it will be a very long time (over two centuries) before a swimmer achieves a 40 second swim. However, the application of scientific findings will improve swim coaching and help a swimmer to achieve Doc’s prediction now.

This document includes five parts to address how to modify technique:
1. Technique Requirements – the technique elements required to swim 100 meters in 40 seconds
2. Technique Adjustments – a step by step process to improve current technique to swim 100 meters in 40 seconds
3. Technique Limitations – typical technique elements that prevent a swimmer from swimming 100 meters in 40 seconds
4. Technique Issues – additional strategies to swim 100 meters in 40 seconds
5. Technique Measurements – analysis methods that identify technique changes to swim 100 meters in 40 seconds
