Abstract

Fitness tracking apps are popular. There is little data validating their use during and after exercise. PURPOSE: Validate an iOS-based pulse oximeter against a fingertip pulse oximeter and a Polar® heart rate monitor during moderate intensity exercise and recovery. METHODS: Age Estimated Maximal Heart Rate (AEMHR) was calculated for fifteen college-aged students. Participants completed a 30-minute running trial divided into three 10-minute segments intended to elicit heart rate responses of 60, 70, and 80% of AEMHR. Heart rate and oxygen saturation data were collected at five and nine minutes of each segment. RESULTS: At 60% the digiDoc® app exhibited a low correlation when compared to the Polar® heart rate monitor. At 70% the digiDoc® app exhibited a low correlation when compared to the fingertip oximeter. During recovery the digiDoc® app exhibited high correlation values at 5PE and 10PE when compared to the Polar® heart rate monitor. The digiDoc® app exhibited a high correlation at 5PE when compared to the fingertip pulse oximeter. CONCLUSION: There is little evidence to suggest the digiDoc® app accurately measures pulse rate and oxygen saturation during exercise or recovery. However, various issues could have led to erroneous readings. This argues for the continuation of this work.

An Examination of the Validity of an iOS-Based Heart Rate and Pulse Oximetry App During And after Moderate Intensity Exercise

Fitness tracking apps are popular. There is little data validating their use during and after exercise.
