The purpose of this study was to develop a method for assessing an athlete’s deceleration ability and investigate its relationship with acceleration distance, % maximum speed and eccentric strength. A Laveg LDM 300C was used to collect peak speed and distance of 9 male athletes in a 30m maximal sprint and acceleration-deceleration efforts within set distances of 5, 10, 15 and 20m. The ‘deceleration gradient’ derived from 10m and 5m peak speeds and stopping distances was found to exhibit a low association with eccentric strength of the quadriceps (R2 = 0.284) and hamstrings (R2 = 0.219). Equations were generated linking % maximum speed attained with acceleration distance (R2 = 0.961) and stopping distance (R2 = 0.851) which could help to set realistic conditions for acceleration-deceleration drills and to revise speed zones within match analysis applications.
