自由泳如何提高效率(第一步)freestyle - Discovering Efficiency, Step 1
When swimmers begin the quest to discover the most efficient freestyle, they often think that Step 1 is to achieve a super-low stroke count. But a lower stroke count doesn't automatically produce a more efficient stroke.
自由泳如何提高效率(第二步)Freestyle - Discovering Efficiency Step 2
In Step 1 of our series on discovering efficiency, we counted strokes. In Step 2, we'll add a simple focus point... speed.
Learning to swim faster without adding strokes will teach you how to get more out of each stroke. It will also clean up your walls, extend your breathing, activate your kick, and teach you a lot about your stroke count as well.
Again, try to maintain the exact stroke count. You may also find that if you try to go too fast, your body will want to add a stroke. Try to avoid this at all costs.
自由泳如何提高效率(第三步)Freestyle - Discovering Efficiency Step 3
Heart rate is the key to Step 3 in our freestyle series on how to discovery efficiency.
By adding heart-rate to the mix, you'll find out if you're truly "efficient"... rather than simply good at getting from one end to the other with minimal strokes.
Use technique to adjust your heart rate, not just increased fitness over time.
