Abstract
Nine games players (mean age 23.3 years, s=2.8; height 1.73 m, s=0.08; body mass 70.0 kg, s=12.7) completed 14 laps of a measured circuit that incorporated intermittent running and directional changes, representative of the movements made by field hockey players during match-play. The distances and speeds recorded by a global positioning satellite (GPS… (More)
