Types of weights trajectory in sntach used by female weightlifters of varius build

The expanded base of technical indicators in weightlifting will greatly simplify the formation of models of motor
actions of the athlete. The aim of the research is to determine type of moptions trajectories of snatch
weightlifting for high-class female heavyweighters depending on atheltes’ weight group and body. Materials and
methods. In the research, data of 263 successful weightlifing snatches by 119 best female weightlifters in the
world were used. Analysis of biokinematic characteristics of motions was done via videograms processing
automated systems on the basis of “Weightliftinganalyzer 3.0” video-computer complex (Germany). Results. In
the research done by us, a certain tendency of motions trajectories possession on the basis of athletes’ weight and
body type can be seen. Thus, the degree of possession of various types of motions trajectories of female athletes
with dolichos form build of lightweight categories is distributed more proportionally with a slight prevalence of
trajectory (B); however this distribution changes with increase of weight categories in the advantage of the other
type of trajectory (B). Thus, the research shows that most female weightlifters of heavyweight categories
perform the snatch using the second trajectory type (B). Female weightlifters of mesomorph and brachimorph
phisique show the opposite tendency. Thus, most weightlifters of lightweight category possess the second type of
snatch trajectory (B). At the same time, with the increase of wieght categories, the share of the second type
significantly decreases while the share of the first (A) and third (C) type increases. Conclusions. The research
showed significant prevalence of the use of the second type (B) of motion trajectory for snatch weightlifting by highly qualified
weightlifters of dolichos form, mesomorph, and brachimorph build. It has been revealed that with the increase of weight
category, the percentage of female athletes of dolichos form build that perform the snatch by the second type of
trajectory (B) increases, while by the first (A) and third (C) type it decreases. It has been revealed that with the
increase of weight category, the percentage of female athletes of mesomorph build who perform the snatch by the second type
(B) decreases, while percentage of those doing it by the first (A) and third (C) type increases. It has been revealed that with the
increase of weight category, the percentage of female athletes of brachimorph build who perform the snatch by the second type
(B) decreases, while percentage of those doing it by the first type (A) insignificantly increases, and by the third type (C) –
increases significantly.
