Maximal kicking performance was determined by terminal ball velocity during a standard indoor soccer kick. The velocity was measured by Doppler radar when the players kicked towards a goal from a distance of 11 metres. Each player performed twenty shots, with the fastest being compared to their performance before the study. Although high-resistance training improved knee extension strength, none of the strength taining techniques had any effect on maximal ball velocity during the shoot-out. Peak ball velocity ranged from 85 to 115 km per hour among all players, but was not different before or after the training period. The investigators concluded that their elite players already had excellent kicking abilities prior to the study,but that such training could possibly benefit less skilled players.
