Purpose: Monitoring the load placed on athletes in both training and competition has become a very hot topic in sport science. Physical fitness can significantly impact the mission success of Special Operations Forces. Much like athletes, Operators have multiple training components including technical, tactical, physical and mental con ditioning, which must simultaneously be developed for mission success. Both scientists and coaches routinely monitor training loads using multidisciplinary approaches, and the pursuit of the best methodologies to capture and interpret data has produced an exponential increase in empirical and applied research. Athlete monitoring systems should be underpinned by appropriate data analysis and interpretation, in order to enable the rapid reporting of simplistic and scientifically valid feedback. Using the correct scientific and statistical approaches can improve the confidence of decisions made from athlete monitoring data. Research Methods: By reviewing the research done in this field as follows little research has discussed and proposed an outline of the process involved in the planning, development, analysis and interpretation of athlete monitoring systems. Results: This review discusses a range of methods often employed to Monitoring Training Load in sports activities using GPS and inform decision making processes. Conclusions: There is a wide range of analytical methods and tools that practitioners may employ within athlete monitoring systems, as well as several factors that should be considered when collecting these data, methods of determining meaningful changes and various data visualization approaches. Underpinning a successful athlete monitoring system is the ability of practitioners to communicate and present important information to coaches, ultimately resulting in enhanced athletic performance.
