Abstract
Provided are a system, method and device for determining one or more physiological parameters of a person.
Core Innovation
The invention provides a method of determining a fitness of a person by monitoring a heart rate, a respiration rate and an activity level of the person with an external, body-worn sensor device. The sensor device stores data of the heart rate, the respiration rate and the activity level in a memory of the sensor device. The method determines, at the sensor device, that the activity level of the person is above a first threshold for a first predetermined time period.
After determining that the activity level of the person is above the first threshold for the first predetermined time period, the sensor device determines that the activity level of the person is below a second threshold for a second predetermined time period. After determining that the activity level is below the second threshold for the second predetermined time, stored data is used to perform, at the sensor device, processes of determining a maximum heart rate, determining a heart rate recovery, determining an aerobic capacity, and determining an anaerobic threshold.
For treadmill-based fitness determination, the method further stores data of a known test including data of a time between increments in an incline of the treadmill and a speed of the treadmill. The aerobic capacity and anaerobic threshold are determined using the stored treadmill test data, including determining aerobic capacity based on treadmill speed and treadmill incline, and determining anaerobic threshold by identifying an inflection point in respiration-rate data and, in some cases, identifying the treadmill speed and treadmill incline when the respiration rate reaches the identified inflection point.
Claims Coverage
The document includes three independent claims: a method for determining fitness, a method for determining treadmill fitness, and a non-transitory computer readable medium for generating and outputting a report. Across the independent claims, there are four core inventive metric determinations triggered by activity-level threshold crossings.
Activity-level threshold triggered fitness metric determination
Monitoring a heart rate, a respiration rate and an activity level with an external, body-worn sensor device; storing heart rate, respiration rate and activity level data; determining that the activity level is above a first threshold for a first predetermined time period; determining that the activity level is below a second threshold for a second predetermined time period; using stored data to perform, at the sensor device, processes of determining a maximum heart rate, determining a heart rate recovery, determining an aerobic capacity, and determining an anaerobic threshold.
Treadmill known-test data storage tied to threshold transition
Monitoring a heart rate, a respiration rate and an activity level with an external, body-worn sensor device; storing heart rate, respiration rate and activity level data; storing data of a known test including data of a time between increments in an incline of the treadmill and a speed of the treadmill; determining the activity level above a first threshold for a first predetermined time period; determining that the activity level is below a second threshold for a second predetermined time period; using the stored data to perform, at the sensor device, processes of determining a maximum heart rate, determining a heart rate recovery, determining an aerobic capacity, and determining an anaerobic threshold.
Report generation on a non-transitory computer readable medium using threshold-triggered analysis
A non-transitory computer readable medium comprising a computer readable program code adapted to be executed by a processor to implement a method for generating and outputting a report that includes data of a fitness of a person running on a treadmill, including monitoring heart rate, respiration rate, and activity level with an external, body-worn sensor device; storing sensor data; storing data of a known test including data of a time between increments in an incline of the treadmill and a speed of the treadmill; determining activity level above a first threshold for a first predetermined time period; determining activity level below a second threshold for a second predetermined time period; and using stored data to perform, at the sensor device, processes of determining a maximum heart rate, determining a heart rate recovery, determining an aerobic capacity, and determining an anaerobic threshold.
Collectively, the independent claims cover threshold-triggered determination of fitness metrics, including maximum heart rate, heart rate recovery, aerobic capacity, and anaerobic threshold, using an external, body-worn sensor device. Treadmill implementations additionally store known-test treadmill data and use it to support the aerobic capacity and anaerobic threshold determinations.
