Exercise Physiology & Tech

Exercise dramatically alters insulin sensitivity. Technology must be adapted before the activity begins.

The Core Divide

Aerobic exercise (running, cycling) typically causes rapid drops in glucose. Anaerobic exercise (heavy lifting, sprinting) often causes temporary spikes due to adrenaline and hepatic glucose release.

The Numbers

For aerobic exercise on a pump, basal rates should typically be reduced by 50-80% roughly 60-90 minutes prior to the activity starting (Riddell et al., 2017).

FAQ

Why did my blood sugar spike after deadlifts?: High-intensity stress hormones signal the liver to dump stored glycogen into the bloodstream.
