The use of generic and individual speed thresholds for assessing the competitive demands of field hockey.
Abstract: The current study compared the running demands of professional
field hockey players using individualized speed zones and generic
default settings of the GPS manufacturer. In addition, the differences
in slow, moderate and fast players were studied. Sixteen
male players from the same club participated in the study (age:
25.5 ± 2.9 years; body mass: 74.6 ± 5.5 kg; stature 1.77 ± 0.05
m). The peak speed of each participant was established at the end
of the data collection period by analyzing all training and playing
data throughout the season. Using players peak speed achieved
for each participant during the season, individualized speed zones
were retrospectively applied to all match-play data. Peak speed
was used to categorize players into three groups, slow (5 players:
29.2-30.2 kmꞏh–1), moderate (6 players: 30.7-31.5 kmꞏh–1) and
fast (5 players: 32.2-33.7 kmꞏh–1). Significant differences were
observed between generic and individual thresholds for the distance
covered in moderate, high, and very high-speed running in
all positions (p = 0.01). Our findings show that the distances covered
at high-speeds in midfielders and forwards were overestimated,
while the very high-speed running and sprinting in backs
were underestimated. Generic speed thresholds should be used if
comparisons between positions is of importance. However, based
on the different capacities of field hockey players, individual
speed thresholds may be more suitable when addressing the relative
stress on individual athletes.
