Contributions related to optimizing mobility indices in gymnasts by means of aerobic gymnastics

Abstract

The aim. The purpose of this research is the formation of gymnasts with
good general and special physical training, apt to meet the competitive requirements
at national level, currently and in perspective. We consider that
the introduction of operational means specific aerobic gymnastics designed
for the increase in indices mobility will result in an increase in. Methodology.
At the start of the experiment, we conducted a series of tests on girls
who want to become gymnasts.. Due to the fact that the athletes subject to
the experiment are aged between 7 and 9 years, most of them having 8 years,
the appreciation of motor quality mobility is only through 2 samples, and for
speed we chose the rehearsal speed. After these requirements, the two tests
specific to articular mobility will be carried out: a) test 1 mobility in lumbar
spine: top bridge; b) test 2 mobility in coxo-femoral joint: lateral string; c)
test 3 repetitive speed: the rigle method. Through these samples, the degree of
lumbar and coxo-femoral mobility was tested. Results. For lumbar mobility,
the top bridge, relevant progress has been made. The coefficient of variability
was in both tests between 0-10%, which means high homogeneity and low
dispersion, ie C.V.i =5.46% and C.V.f= 6.8% with a decrease of 1.3% of
homogeneity at the final test. For the mobility of coxco-femoral joint, lateral
string, significant progress has been made. The coefficient of variability
was between 4.09% and 4.60%, which shows us that the homogeneity of the
group is large C.V.i. = 22.5% and C.V.f. = 42.5%. For the repetition speed,
the homogeneity of the group is high both in the initial test and the final test,
the group losing homogeneity in the final test. At this test C.V.i. = 2.83%, and C.V.f. = 3.92% dispersion being very small. Conclusions. Following the
analysis and interpretation of the statistics indicators presented in the tables
and studying the initial and final data presented, the main statistical indicators
were discussed: average deviation, standard deviation and variability coefficient.
