Summary: A marker-free video measurement and image processing method
that provides numerical estimation of the 2-D centre of rotation of one
rigid segment is tested. The algorithm is based on binary region moment
features. A comparison is made between this method and a marker-based one,
where the location of the markers has been calculated in two ways. The
algorithm is also extended to handle two rigid segments. The method is to
be applied in human locomotion analysis in order to calculate the centre of
rotation of the hip joint. It's accuracy has been tested by comparison with
in vivo radiological measurements on humans.
Keywords: gait analysis, kinematic, hip joint, centre of rotation, image processing

Summary: We have studied skilled human locomotions in sports
gymnastics by measurement and analysis of ground reaction force and
myoelectric signals. Assuming the quality of performance to be skill level
criterion acquired signals were mathematically analyzed via basic signal
processing and cross-correlation methods. The study of backward somersault
yielded quantitaive criteria of performance, proposing an original measure
- an inter-muscular cross-correlation function. Besides motor learning, the
quantification of movement skill introduced here also relates to possible
applications in biocybernetics, robotics and rehabilitation medicine.
Keywords: electromyography, gymnastics, locomotor skill, muscle coordination, neuro-mechanics

Summary: The aim of the investifation was to establish the
morphological status of perspective, promising alpine skiers in Croatia and
to evaluate their morphotype. The investigation was carried out on a sample
of 17 males, aged 15-17 years. 17 anthropometric variables and the
Heath-Carter anthropometric somatotype method were applied. The
anthropometric variables were selected to completely cover the
morphological status of the subjects, and the measurements were carried out
in accordance with the standards stated in IBP. The obtained data were
analyzed according to the usual procedures for determination of the basic
descriptive statistic parameters. It was established that it was a selected
sample which was somewhat taller (177.0 cm) and heavier (67.3 kg) than
normal population, with higher circular dimensions of the body, but the
quntity of subcutaneous adipose tissue was significantly smaller than with
normal population. According to the Heat-Carter method young skiers were
mesoectomorphic (I=2.37+0.48;II=3.79+0.89;III=3.13+1.25).

Summary: The purpose of this study was to estimate the physiological
characteristics of perspective alpine skiers. 17 perspective, perspective
according to the opinion of their choaches and experts in Croatian Ski
Federation,skiers, boys at the age span 15-17 years, were involved in the
investigation. Body height and mass and spirometric parameters were
measured. Maximal oxygen intake and the other spiroergometric variables
were measured directly during the continious progressive test on a
treadmill. The strength of 4 attempted movements was measured as well as
the speed of dominant leg. According to the Rohrer and Kahlstorf's method
heart volume, absolute and relative, was determinated. The obtained data
were submitted to the standard statistical methods to determine descriptive
parameters. 177.0 cm tall and 67.3 kg heavy skiers had on average FVC of
6.0 l and FEV1 5.4 l(90%). The average value of our examinees heart volume
(946.5 ml) is above the average values of nonathletes. This is particularly
shown in the values of relative heart volume. The average value of the
heart volume quotient is very good and indicates good economy and
functional capability of cardiovascular and cardiopulmonar systems, what is
also shown from the values of oxygen pulse. Absolute and relative maximal
oxygen intake are significantly higher than mean values in normal
population of the same age span.
