Okay, so I read it. Resistence respiratory muscle training is crap for Underwater Hockey Players. The study if for divers on SCUBA and how resistence training helps them to last longer breathing at depth. Since we breathe at the surface the part that is critical for us is this result:

"Impact of RMT on swimming performance
Following RRMT, surface swimming times improved
33% and underwater swimming times improved 66%.
Following ERMT, surface swimming and underwater
swimming times improved 38 and 26%, respectively.
Results of this study suggest that the endurance per-
formance improvements were not due to changes in
the aerobic fitness of the subjects since it was un-
changed throughout the study."

Seems the endurance respiratory muscle training is what we need to work on.

And if you read it close you see that they took swimmers and gave them 12 whole sessions with a snorkle and a dive class. So the level of fitness they started at was fine but their skill at breathing through a device was non-existent just one month before their study. Very similar to taking a break from hockey and staying fit doing other things then coming back and having to get hockey fit again. I still stand by what I've said throughout this thread.
