New issue of #TheSickTimes includes a study that found no evidence that wearable alerts improve pacing.

Not super surprised by this.
The alerts themselves can trigger emotional and sensory exertion.
The data they're generally tracking includes just one type of stressor (physical) - I have yet to find a wearable that can (for example) track emotional overload via voice characteristics; track cognitive load via things like "time spent on computer"; track sensory stimulation via light and sound levels and rate of change.
The proportion of time spent resting and type of rest is a critical factor that is also generally not tracked: vertical vs horizontal vs reclined; physical vs cognitive vs sensory and emotional; degree of stressors and type of stimuli present.
As long as a trial fails to track rest as well as the different types of exertion, impact will be buried in the noise.
