Garmin has been granted a patent for a method, device, and computer program product that determines the training load distribution of a user. The method involves continuously measuring heart rate using a heart rate sensor and calculating aerobic and anaerobic training effects and loads based on intensity values. The training load is then divided into categories of Aerobic Low, Aerobic High, and Anaerobic, and the distribution is outputted to an output device.

Determining training load distribution based on heart rate measurements
A recently granted patent (Publication Number: US11771355B2) describes a method for determining the training load distribution of a user using a device with a processor, memory, and software. The method involves continuously measuring heart rate using a heart sensor and recording the measured values. Intensity values depicting exercise intensity are obtained either by calculating exercise intensity using the measured heart rate values or by measuring external workload.
The method calculates aerobic and anaerobic training loads and effects based on the intensity values and determines high-intensity periods and their characteristics. The aerobic training effect is divided into intensity categories of Aerobic Low and Aerobic High, scaled based on the user's fitness level. Activity class-based target values for monthly training load are determined for each intensity category. The calculated training load is stored in three intensity categories: Aerobic Low, Aerobic High, and Anaerobic, providing a distribution of training load between these categories. The training load distribution is outputted to an output device.
The patent also describes the further division of intensity categories into sub-categories. The Aerobic Low category can be divided into sub-categories of Recovery and Base, while the Aerobic High category can be divided into sub-categories of Tempo, Lactate threshold, and VO2 max. The Anaerobic category can be divided into Anaerobic capacity and speed.
The method classifies workouts into categories based on the aerobic and anaerobic training effects and time spent at different intensity zones during the workout. These categories depict the physiological benefit of the workout. The intensity is measured as a relative intensity benchmarked against various factors such as lactate threshold heart rate, lactate threshold speed, functional threshold power, VO2 max, and speed/power corresponding to VO2 max of the user.
The distributed training load is calculated by summing all accumulated training loads of each intensity category. The training load distribution can be outputted as a daily calendar, weekly illustration, monthly illustration, custom date specified by the user, or yearly distribution.
Overall, this patent describes a method for determining and distributing training load based on heart rate measurements and exercise intensity values. The method allows for personalized training load targets and provides guidance based on the accumulated loads and personal targets. It also offers the ability to analyze and classify workouts based on their physiological benefits.
