This is the page I’ll be updating with the results

During the early 1990’s, Graeme McMahon monitored the heart rates of climbers using various canopy access systems.
In comparing spurs, prussic, frog and yosemite, he found the single rope technique (SRT) systems were an efficient method of access.
This had been long known within the caving, rock climbing and other rope access industries.

The video was part of a presentation to Arboricultural Association of Australia (AAA), included was Graemes research.
In the coming weeks, I’ll be making a post on our website with the charts, tables and documentation as pdfs.

Tape was used in the systems, as part of the research was to compare the efficiency gains/losses of shortening and lengthening these. Modern systems are tailor made to the right length to reduce bulk.
