Description

A sports activity monitoring system

technical field

The invention relates to the field of sports activity monitoring, in particular to a sports activity monitoring system.

Background technique

Physical activity is important to maintaining a healthy lifestyle and is a source of entertainment for many people. Some individuals prefer to participate in team sports, such as soccer or basketball, while others prefer to participate in individual sports, such as running or skiing. Whether the activity is a group or individual activity, it is common for people to participate in competitive events such as soccer games or running races, as well as more informal training sessions such as conducting soccer drills or interval sprints.

Many existing fitness monitoring devices are not portable and thus not suitable for providing monitoring in many real-world competitive or training events. Even portable ones are often too heavy, or lack sufficient battery and/or processing power, to be used for extended periods of time under rigorous competition or training conditions. Furthermore, while some existing fitness monitoring devices are capable of relatively simple performance measurements, such as an individual's current heart rate or total steps taken during an activity, more advanced measurements are often not available or accurate. Finally, performance feedback provided to individuals through existing devices often does not provide quick, accurate, insightful information that allows them to easily compare with past performance, develop strategies for improving future performance, visualize performance, or select new training Scheme or sports equipment.
