Physical demands and physiological responses during elite field hockey.

The aim of this study was to determine the physical demands of elite men's field hockey using modern time-motion analysis techniques. 18 elite male players (age: 24.4 ± 4.5 yrs) participated in 5 matches, during which physical outputs of players were quantified using GPS units and heart rate monitors. The mean total distance covered by each individual player was 6798 ± 2009 m. Mean total distance covered per position for 70 min (position (70)) was 8160 ± 428 m. Distance covered per position (70) decreased by 4.8% between the 1 (st )and 2 (nd) halves ( P < 0.05). Fullbacks covered significantly less total distance than all other positions ( P < 0.05). High-intensity running (>19 km.h (-1)) comprised 6.1% (479 ± 108 m) of the total distance covered and involved 34 ± 12 sprints per player, with an average duration of 3.3 s. Average HR was higher in the 1 (st) half (86.7% HR (max)) than the 2 (nd) half, (84.4% HR (max)), though this was not significant ( P = 0.06). The results suggest that modern day elite field hockey is a physically demanding team sport. Quantification of the demands and outputs of players at this level provides a useful framework on which to develop conditioning practices. The difference in physical outputs observed for some positions suggests position-specific conditioning is required at the elite level. © Georg Thieme Verlag KG Stuttgart · New York.
