Hmm never considered a "parachute effect" could be comparable/noticeable to forces during water start.
Nevertheless, I have old-schools shorts made of really tough waterproof fabrics. Will give them a try today - just out of curiosity. Will report later ))
UPDATE:
Did two sets
- first (just to make experiment as clean as possible) in swimming jammers.
- second in the above mentioned shorts of heavy nylon fabrics (water hardly goes through).
Did not notice any difference in resistance - I am sensitive for it because my hands are not very strong.
But noticed another effect of that shorts - they make water streams (or water channels) inside itself.
If knees are not close - water hits... guess where ))
If knees are tight together - water goes up through belt area under back of the west, then when Im up, water goes out from the west ... strange feeling...
May be there could be some "parachute effect", but in fact this effect is a function of square which is resisting to movement. The little square added by shots is less than a fraction of percent comparing to sum of squares of ski, lower body, upper body, hands etc. - may be noticed only on psychological level.... IMO
