From: Effect of playing position and microcycle days on the acceleration speed profile of elite football players

Variable

Definition

A0

Maximal theoretical acceleration (ordinate axis intercept (y) in A–S linear regression)

S0

Maximal theoretical speed (abscissa axis intercept (x) in A–S linear regression)

ASslope

Linear slope. Calculated: -A0/S0

ACCmax

Maximal acceleration (m/s2)

Smax

Maximal speed (m/s)
