Aug 11 - Day 8 Back on the Kili trails…

The expedition team are back in action following two days of testing at camp Shira at 3500m. The rest would have been a very welcome break for some tired legs and sore feet! With the team enjoying the spectacular views and each other’s company, the research scientists are more focused on their laptop screens and capturing the data vital to the success of the Mayo Clinic project.

The scientists are heavily reliant on the quality of the physiological signals to support their research efforts. The added complexities of operating in such a demanding environment places additional pressure on the technology. Biovotion are in great company with @Philips as the other technology partner of the expedition. For example, with the Philips CX50 xMATRIX that is bringing ultrasound capability to the lab in the sky. Assisted by such cutting edge technology Mayo will seek to accelerate and deepen their understanding of the body’s ability to tolerate oxygen deprivation.
In parallel to that The expedition research team will test the effect of 1,000 mg daily of nicotinamide riboside on altitude tolerance, cardiovascular fitness, and team cohesion.

For those with blisters and suffering the thinning air (in the name of science!), they put back on their walking boots this morning and continued up the hill! This will be by far the most challenging day on the ascent to date, and the first time they will breath air above 4000m as they head to the Moir Camp at 4200m. To put this in perspective, the world’s fastest endurance athletes use altitude as part of their training preparations in order to push their adaptive responses and fitness levels to the maximum. The Kenyan high altitude centre, home to multiple world record holders and multiple Olympic champions is at a rather meagre 2400m! Spare a thought for the subjects when you run up a flight of stairs today!!

These additional demands are reflected in the significant compensatory responses identified by the VSM1.

A sedentary office day with 7’493 steps, an average Heart Rate of 74 and Blood Pressure wave of 2.22.

Compared to that hiking and climbing at 7,600ft with 20’053 steps and an average Heart Rate of 112 and Blood Pressure wave of 2.89.
