If you come from an older generation of swimmers you may have been taught a technique called the ‘S-Pull’. This is a swim form developed in the 1970s and saw use for a couple decades in the competitive circuit. The goal of the S-Pull was to increase the length of each pull using an S shape: Beginning the stroke with the thumb down, sweeping outwards, and then sweeping back in by the hips. If you’re having a hard time visualizing this, imagine the movement your arm makes when putting on and taking off a towel. The two are basically the same.
However, the technique was created without taking into account the rolling of the body it generates. Also, next to the modern vertical or ‘I-Pull’ techniques, the S Pull has many drawbacks:
· Forcing your palms outwards while entering the water can cause shoulder injuries.
· Your ability to reach further to grab a still anchor point is diminished.
· The path of a swimmer’s hands is arched, pushing water partly sideways rather than straight back, losing efficiency.
So if you’re still using the S-Pull try switching to a straighter form. You want to lengthen your reach so you can anchor in non-moving water, keeping your elbows up, without a small arch. Your hands should only be tilted 45° and kept closed. And when flutter-kicking remember to use your whole leg, with your feet barely breaking the surface, keeping your core contracted to keep your hips from rocking.
Another interesting question is if stroke technique should differ when swimming 50, 100 and 200. It's obvious that when swimming 200 you make longer strokes and it's perfect for S-shape pull but what about 50? Personally I also noticed that S-shape pulls decrease DPS from 43-45 to 36-38 per 50m. Though S-shaping isn't easy with such intensity. Nevertheless I noticed on videos that even Cesar Cielo makes catch with slight out swiping so he at least makes ? mark.
