Latency effects of IoT devices for measuring sports activities

Abstract

The Internet of Things (IoT) is increasingly being used in sports science to monitor performance, biomechanics and physiological parameters. However, latency, delay in data transmission and processing can affect the accuracy of measurements, especially in laboratory conditions where high precision is required. This paper analyzes the latency effects of IoT devices by different solutions, using a comparison of latency results, system architecture models, transmission media and other parameters. The results show that latency can cause significant deviations in the measurement of reaction time and biomechanical parameters, but it can be partially compensated by software methods, adequate selection of data transmission technology, and considering the choice and method of application of IoT devices as detection sensors. The consequences of latency can lead to an injury to the athlete or to a delay in giving feedback due to a mismatch in timing.
