00:00Hey guys, Grace Hamilton here from the Illawarra Mercury Sports Team.
00:03Today we are trying something a little bit different.
00:05I am here at Airlocker Wollongong, testing out the gym facilities
00:09where the altitude is elevated and the oxygen is decreased.
00:16This is our altitude display unit.
00:19This data here is fed by the O2 sensor,
00:23which is on the back wall of the room just over there.
00:25That's the set point, so that's what it's trying to get to,
00:28and that's what that O2 sensor is reading.
00:31So it'll keep pumping and pumping and pumping until that number gets to the set point
00:35and then it'll flick off.
00:36It'll flick back on and off as it comes back up just to keep it at that set point.
00:42Over here is our simulated altitude level.
00:44So that is the equivalent altitude of what 14% is.
00:50So if we were at 3,500 metres above sea level on a mountain somewhere,
00:54we would expect to see around 14% oxygen if we took a live reading in real life.
00:59I was very kindly allowed to use the facilities for about 30 minutes,
01:03so I ran through a super quick weight session, only four exercises.
01:07It took about 30 minutes and I burnt just over 400 calories,
01:10which is definitely more than I usually do in a 30-minute session.
01:14One thing I did notice that was different was my breathing.
01:16I felt that it was a little bit harder to breathe or get the oxygen from a breath,
01:21which is what altitude training also works to improve,
01:24so that you don't struggle as much in your usual training or on a bike ride or while hiking.
01:29This little device reads your SpO2 or your blood oxygen saturation.
01:34In the outside air, it's usually 96.
01:36In here, it can get down to below 90.
01:38The target for me on this day was around 94.
