Overall Readiness
Your Overall Readiness Score takes into account all recorded metrics to produce a score out of 100. You are also provided with a Readiness Summary that provides an overview of your state as well as any weaknesses. Swipe on the ring to see how your Readiness has changed over the past week or six weeks.
Cognitive Readiness
Your Cognitive Readiness Score (0-100) is made up of the following metrics:
- Trained Reaction Time (TRT): TRT is the average of all responses within the range of 100 milliseconds to 500 milliseconds.
- Lapses (LT): Lapse time counts the total number of slow responses. For the readiness assessment system, lapses are counted for any response slower than 500 milliseconds for a reaction time question. A higher than normal number of lapses is a good indicator of increased mental fatigue.
- Misses: Misses are any failure to respond to a reaction time question lasting longer within 2 seconds.
- Mental Load: Mental Load (0-100) is a ranking of how mentally demanding yesterday was.
- Cumulative Mental Load: Cumulative Mental Load (0-100) is a rank of how mentally demanding your last four days have been.
- Sleep: Sleep measures the hours of sleep (not time in bed). This data is currently pulled from Oura, Apple Health or Google Fit. Oura, Apple Health and Google Fit integration can be found in the app settings section.
Physical Readiness
Your Physical Readiness Score (0-100) is made up of the following metrics:
- Resting Heart Rate: Resting heart rate measured in heartbeats per minute over the course of the session. To ensure validity please make sure that you take the test in a resting state. You can collect HRV by connecting a heart rate monitor or connecting a health app like Oura Ring, Apple Health or Google Fit.
- HRV: Heart rate variability is the measure of the beat-to-beat variability between heartbeats. Known as a very reliable measure of both physiological and psychological stress it is used as a standard metric for training across most sports. Rewire uses the gold standard calculation for HRV known as rMSSD which stands for the root mean square of successive differences. This is the same standard used by many well-known HRV apps and tools though it is useful to note that there is no standard for the scale factor applied to HRV which is why from app-to-app the measurements are slightly different. You can collect HRV in the Rewire app by connecting a heart rate monitor or you may also override Rewire’s HRV calculation by syncing to Apple Health or Oura Ring and selecting the “Use HRV data from this source” found under integration settings.
- Sleep: Sleep measures the hours of sleep (not time in bed). This data is currently pulled from Oura Ring, Apple Health or Google Fit. Our Oura Ring, Apple Health and Google Fit integration can be found in the app settings section.
- Training Load: Training Load (0-100) is a ranking of how physically demanding yesterday was.
- Cumulative Training Load: Cumulative Training Load (0-100) is a rank of how physically demanding your last four days have been.
- Muscle Fatigue: Muscle Fatigue (0-100) is a subjective ranking that provides a strong indicator of physical fatigue.
Emotional Readiness
Your Emotional Readiness Score (0-100) is made up of the following metrics:
- Level of Rest: Your self-assessment of your level of rest. Generally, your first instinct is most accurate. This is ranked from 0 to 100 with 0 signifying the lowest level of rest and 100 the highest level of rest.
- Level of Readiness: Your self-assessment of your level of readiness to perform. Generally, your first instinct is most accurate. This is ranked from 0 to 100 with 0 signifying the lowest level of readiness and 100 the highest level of readiness.
- Level of Stress: Your self-assessment of your level of stress (both physical and psychological). This is ranked from 0 to 100 with 0 signifying the lowest level of stress and 100 the highest level of stress.
- Level of Frustration: Your self-assessment of your level of frustration. An increase in frustration is generally a strong indicator of cognitive fatigue. Generally, your first instinct is most accurate. This is ranked from 0 to 100 with 0 signifying the lowest level of frustration and 100 the highest level of frustration.
These subjective metrics were developed by Nasa for testing the readiness of astronauts. The testing protocol is called the NASA Task Load Index (TLX).
