Open Water Diver courses finished

A part of the master course is to use the intermediate deacclimatization between study legs on Mauna Kea for earning the Padi OWD with instructor Dr. Netzer (PADI OWI 955155). Physiology and medicine of scuba diving are also part of the course program titled “ understanding hypoxia from bottom to top“. Regular scuba diving theory will be extended by special medical, technical and psychology knowledge in an extra weekend in Innsbruck end of Jan 2015. Famous scuba diving journalist and long term „Tauchen“ EDIC Heinz Käsinger will be teaching on this weekend. The OWD course started already together with the normobaric simulation leg of the Mauna Kea hike in Bad Aibling. There, also between study legs, the pool sessions took place and the theory lessons together with the written test. Now, here on Big Island the free water dives took place at Mahukona and Honaunau. Two days ago every student had sucessfully finished its OWD. Now at Puako house nr 40 and at mile marker 4 in Kona the first free dives made a lot of fun with a close by swiming Manta and many turtles under water. Fun Scuba! Pictures show first free water dive at Mahukona and exercising the Cesar at Honaunau

uibk hbi mauna kea study group

On day 4 of our study group-master course excursion we started with the field study leg of our hypobaric-normobaric comparison study at Mauna Kea. The primary outcome parameter of our comparison between the hike to Mauna Kea summit in the field and simulated at the Hermann Buhl institute in Bad Aibling is the shape of the flow volume curve and the single breath to breath comparison in the ergospirometry. On the picture you see one of the subjects with the oxycon mobile at the start point of the hike near the Mauna Kea visitor center at 2800m altitude. The ergospirometry has been repeated in each of the six subjects at the summit at 4169m altitude after the standardised hike in six hours plus one hour breaks.
Secondary parameters are the oxygen saturation and heart rate as well as Lake Louise score at several time points during the hike.
The conditions on this first field day were unexpectedly tough with constant sunshine, no wind and unusual temperatures at all altitudes above 85degrees Fahrenheit respectively above 26-27 degrees celsius. This lead to unexpected electrolyte loss through more sweating than in the simulated hike.
Performing the ergospiro at the summit took until darkness with a beautiful sunset and clear view on the stars but temperatures dropping to 38 degrees F, 1-2 degrees Celsius.
We are thankful to a National Park UH Ranger who drove half of the group down to our second car before the last ergospiro at 7.07pm was finished.


University Innsbruck Mouna Kea Study Group

Hello, this is the blog of the Professor Netzer Master Course (scientific problem solution in sport and health) from the Sports Science Institut of the Faculty for Psychology and Sportscience at the University of Innsbruck, Austria.
In the Hermann Buhl Institute for Hypoxia and Sleep Medicine Research in Bad Aibling we started our master seminar and the Mouna Kea Normobaric-Hypobaric Hypoxia Comparison Study 5 weeks ago. We simulated the climb from the start of the Mouna Kea trail at 2800m to the top at 4169 meters on a treadmill in normobaric hypoxia, one weekend without a climatization night at 2800m and one weekend with an acclimatization night. Now on Dec. 8th we arrived in the Big Island to perform the study protocol in hypobaric hypixia on site at Mouna Kea.
