Tottenham Hotspur players are training with the Microgate SEM system. Witty SEM is the newcomer to the Witty family: a "smart indicator" composed of a 7x5 LED matrix that can display different symbols and colours. Thanks to the built-in proximity sensor, Witty SEM is the perfect solution for optimal planning and management of specific training for reactivity, agility, and motor-cognitive abilities. Flexible configuration of the system makes it possible to manage and customize various types of tests via the Witty timer and the Witty Manager software: • Witty SEM indicator as a start semaphore with or without countdown to manage starts at pre-set times • Agility tests. Various agility test modes available using the indicator in standalone mode or in combination with a photocell. • Direction change tests • Reactivity tests for specific work on motor-cognitive and coordination skills.
