I don’t read German, but it seems to me that if they were serious about selling it to freedivers they would give some examples of how it can increase performance. Maybe some testimonials of people who’s dynamic or cb increased by so much when using the fins. Instead of showing some guy swimming around in the pool, show him doing a 150-meter dynamic.
The idea is interesting. Diving with arms by the side is not as hydrodynamic as above the head, but obviously you would be able to spread the workload out over more muscles. Would using the fins brining more muscles into play increase O2 consumption or would taking some of the load off the leg muscles counter this? Not having the stress of hold the arms above the head for a couple of minutes should have some advantages as well.
A person should obliviously be able swim faster, but would this be a benefit in distance. The idea seems too simple to not have been tried before. I think I will try some dynamics with my wife’s fins on my hands the next trip to the pool.
As usually I can’t get into the AIDA International web site to check the rules, but I’m pretty sure there isn’t a rule that would stop their use in dynamic. CB on the other hand, has an “only” equipment rule for meets that might prevent their use.
Thanks for info and link.
