High-speed actions are known to impact soccer performance and can be categorized into actions requiring maximal speed, acceleration, or agility. Contradictory findings have been reported as to the extent of the relationship between the different speed components. This study comprised 106 professional soccer players who were assessed for 10-m sprint (acceleration), flying 20-m sprint (maximum speed), and zigzag agility performance. Although performances in the three tests were all significantly correlated (p < 0.0005), coefficients of determination (r2) between the tests were just 39, 12, and 21% for acceleration and maximum speed, acceleration and agility, and maximum speed and agility, respectively. Based on the low coefficients of determination, it was concluded that acceleration, maximum speed, and agility are specific qualities and relatively unrelated to one another. The findings suggest that specific testing and training procedures for each speed component should be utilized when working with elite players.

- Testing soccer players (2005, methodology): “The coach or trainer should also use agility tests in conjunction with single-sprint tests to obtain a thorough indication of players’ speed capacity (Little & Williams, 2003).”
- Developing football expertise: a football-specific research review (2012, background): “The latter argument has been supported by the fact that important physical skills such as maximum speed, acceleration and agility were shown to be specific qualities and relatively unrelated to one another (Little & Williams, 2005 ).”
