CHASKi Running Validation Study: Preliminary Results

We recently conducted a preliminary study to further validate CHASKi’s technology against the gold standard on the treadmill. Similar to our cycling validation study, we are comparing CHASKi’s evaluation of ventilatory thresholds and respiratory frequency with ergospirometry. This study involved 14 volunteers of varying ages and sports disciplines. Our preliminary results show high agreement between CHASKi …

Protocol for ventilatory threshold determination test

Our test is maximal and stepwise, starting with a 3-minute warm-up at 50 watts, then ramping up to 100 watts with 20 watt increments every 80 seconds until exhaustion. You can download this protocol for Zwift at the following link. To load it in your Zwift session, you must access in your computer to Documents/Zwift/Workouts/###### …
