Power Output

In "theory", your power output, during a prusik, is proportional to mass times speed*, so it might "seem" as if it is simple to calculate. Unfortunately, though, the figures given in the tables will be a significant over-estimate because - in the rig we are using - the prusiker is not actually moving vertically. Its like the difference between jogging on the spot and running uphill. We are considering how we might build a better rig that better measures the effort of prusiking "uphill".

* Potential energy, E = m g h, where m is mass, g is acceleration due to gravity (9.81m/s²) and h is height. If t is the time taken then the power output is E / t.
