Introduction
urrently, most top high jumpers use
one of the versions of the Fosbury
Flop technique
1
. The technique, which
comprises the approach, the preparation for
the take-off, the take-off, the flight phase and
bar clearance and the landing
2
, is differenti-
ated from the other jumping styles mainly by
the so called “J” approach and back lay-out
position used to cross the bar.
The single most important factor and es-
sential contributor to the height cleared, is
the height of the flight of the body’s centre of
mass (BCM), which is a result of the vertical
impulse produced during the take-off phase
3,4
.

ABSTRACT
The purpose of the present study was to in-
vestigate the three-dimensional kinemat-
ics of contemporary high jump technique
during competition and to compare the re-
sults with findings from previous elite-level
events. The participants in the women’s
high jump event of the European Athlet-
ics Premium Meeting “Thessaloniki 2009”
served as subjects. The jumps were re-
corded using three stationary digital video
cameras, operating at a sampling frequen-
cy of 50fields/sec. The kinematic param-
eters of the last two strides, the take-off
and the bar clearance were extracted for
analysis through software. The results in-
dicated that the kinematic parameters of
the approach (i.e. horizontal velocity, stride
length, stride angle, height of body centre
of mass) were similar to those reported in
the past. However, a poor transformation
of horizontal approach velocity to vertical
take-off velocity was observed as a greater
deceleration of the swinging limbs could be
seen at the instant of take-off. Consider-
able backward lean at take-off, large take-
off angle and inefficient bar clearance
were also noted. The authors recommend
that the athletes studied consider giving a
greater emphasis to the key technique ele-
ments of the take-off phase and of the bar
clearance.
