On your Biostrap main dashboard, you'll see the three main summary scores (Activity Score, Recovery Score, Sleep Score) calculated by the Biostrap proprietary algorithm. Then below are your Steps and Active Calories for that day as well as your Heart Rate, Heart Rate Variability, Respiratory Rate and Oxygen Saturation from your previous night's sleep session.


Heart Rate Variability

HRV is the measurement of variability in time intervals (milliseconds) between heartbeats, reflecting function and balance of the autonomic nervous system. 

It is well established that HRV is a reliable measurement of physical and mental health in relation to the body’s ability to adequately respond to and recover from stress. HRV is influenced primarily by age, health status, gender and lifestyle habits.

While population ranges exist, you should focus on monitoring changes in your personal HRV values over time. In general, a steady increase in HRV values overtime is favorable, whereas a rapid increase or decrease may be indicative of overtraining or an underlying health concern.

*Biostrap utilizes root mean squared standard deviation (RMSSD)

Resting Calories

An estimation of caloric requirements to maintain normal bodily functions, typically accounting for 60-75% of total caloric expenditure.

Active Calories

Total calories burned while moving.

Workout Calories

Total calories burned during a recorded activity.

Steps Calories

Total calories burned through steps only

Respiratory Rate

It is measured in breaths per minute (bpm), is the rate at which you breathe. The normal range for respiratory rate in healthy adults is 12 to 20 breaths per minute. Respiratory rate tends to remain relatively stable day-to-day. 

Rapid changes may be indicative of illness or an underlying health concern.

Oxygen saturation

It is measured as a percentage (%), is the fraction of oxygen-saturated hemoglobin relative to the total.

The normal range for SpO2 in healthy adults is 95 to 99% at rest. Oxygen saturation is dependent upon factors including activity level, respiratory rate, environmental conditions (i.e. altitude), and cardiorespiratory health. Lifestyle habits such as smoking have been shown to decrease SpO2.
