TLDR
Detailed GPS analysis of the physical demands of international Rugby Union players may assist sports medicine professionals in understanding the demands of the game and mechanism of injury, as well as improving injury rehabilitation.Abstract:
Study Design Descriptive. Objectives To evaluate the physical demands of an international Rugby Union-level game using a global positioning system (GPS). Background Elite Rugby Union teams currently employ the latest technology to monitor and evaluate physical demands of training and games on their players. Methods GPS data from 2 players, a back and a forward, were collected during an international Rugby Union game. Locomotion speed, total body load, and body load sustained in tackles and scrums were analyzed. Results Players completed an average distance of 6715 m and spent the major portion of the game standing or walking, interspersed with medium- and high-intensity running activities. The back performed a higher number of high-intensity sprints and reached a greater maximal speed. Body load data revealed that high levels of gravitational force are sustained in tackling and scrum tasks. Conclusion The current study provides a detailed GPS analysis of the physical demands of international Rugby Union p...read more

TL;DR: The presence of ‘temporary fatigue’ reflects this process, whereby exercise intensity is consciously modulated from within the framework of a global pacing schema, as well as avoiding the harmful failure of any physiological system.

TL;DR: The results show that the GPS devices have an acceptable level of accuracy and reliability for total distance and peak speeds during high-intensity, intermittent exercise, but may not be provide reliable measures for higher intensity activities.
