The invention concerns wearable electronic devices, systems and methods for sports performance monitoring. In one embodiment, the invention provides a device comprising a heartbeat sensor for providing a heartbeat signal, a motion sensor for providing a motion signal and processing means adapted to calculate at least one performance parameter depicting said sports performance and/or the person using temporal characteristics of periodic features of the heartbeat signal compared with temporal characteristics of periodic features in the motion signal. The invention allows for utilization of an existing relation between cadence and heart rate for characterizing the performance or the person in a novel way.

Wearable sports monitoring equipment and method for characterizing sports performances or sportspersons

The invention relates to wearable electronic equipment and method for measuring heart rate or muscular activity of a person. The equipment comprises one or more heartbeat or muscular activity sensors for providing a heartbeat or muscular activity signal, respectively, and a motion sensor for providing a motion signal corresponding to movement of the person. In addition, there are provided processing means for detecting from the heartbeat or muscular activity signal first events corresponding to individual heartbeats or muscle activations, respectively, and from the motion signal second events corresponding to movement changes stronger than a predefined threshold. The processing means are further programmed to form a first time series of said first events, and to determine the heartbeat or muscular activity parameter using the first time series. According to the invention, the processing means are programmed to omit from said first time series those first events that coincide with and/or take place at the same frequency as the second events. The invention helps to remove motion-induced artifacts from ECG and EMG signals for more accurate sports performance monitoring and characterization.

Wearable sports monitoring equipment for measuring heart rate or muscular activity and relating method

The invention relates to sports monitoring equipment and methods. The invention provides a device or system comprising means for reading a heartbeat signal corresponding to heartbeat of the person during the performance, and means for reading a motion signal corresponding to motion of the person during the performance. There are also computing means for estimating energy consumption of the person during the performance using one or both of said signals. According to the invention, the device or system further comprises means for determining the type of the sports performance. The computing means for calculating the energy consumption parameter are adapted to utilize said heartbeat signal, said motion signal or both signals in combination in a manner depending on the type of the sports performance determined. The invention allows for accurate estimation of energy consumption in versatile sports.
