The present research was carried out through the application of a plyometric training program for 8 weeks, performing the 3 weekly sessions, in order to determine its influence on the power of the lower body in the athletes of the futsal team Boyacá with diagnosed cognitive disability with borderline mental delay. The intervened population were 10 athletes, with an average age of 20.10 ± 1.9 years, average height of 174.10 ± 9.757 centimetres, average weight of 67.60 ± 10.178 kilograms; A study of the participants was carried out demanding the Axon Jump platform and the Carmelo Bosco protocol, a plyometric training program based on ATR planning was designed and applied, and finally the evaluation was reapplied to athletes. It follows that the p-Value from the test (bilateral sig.), it presenting value greater than .05 in the three jumps, assuming both equality of the variances and different variances, which induces that the differences between the improvement percentages and the players of the trained group with plyometric emphasis and the control group did not differ significantly in the maximum relation, reactive and explosive power indicators.
The vertical jump measure the impulsive capacity, the main goal of this study is describing the coordination and elastic and contractile components of professional soccer players when performing the power test, through jumps, made on the Axom Jump 4.0 contact platform. It is an applicative study, since it carried out a jump test which provided inputs to define the training from the evaluated athletes must do. Sample population was 9 players who acted as midfielders average age: 22 years, size: 1,77: weight: 73kg and BMI of 23.38, power was achieved through the Abalakov, SJ and CMJ jumps. The coordination and elastic influence was determined and correlated with BMI and compared with the other national and international populations. The IMB SPPS Statistics version 24 program was considered for the statistics. The assumption of normality was verified by applying the Shapiro-Wilk test and the correlation and differences with the parametric statistics were established. The power obtained was from 848,4 in the ABK, 845,0 w in the squat jump and 844,2 w in CMJ, which represents acceptable values against an international parameter. The jump valuation is related to the IE of the muscle fibres from the lower bod, and the CB which indicates the coordinative capacity of the players, the relationship of these determine the contribution of the muscle fibres, in this type of case the 9 evaluated players present very high values of muscular work or IC.
Objective: The results of the stroke cycle kinematic analysis of a group of kayakers from a city of Colombia are presented, using a motion capture platform based on inertial and magnetic sensors. Method: Quantitative approach of a cross-sectional descriptive type. A group participated with similar anthropometric characteristics such as size, mass, and body mass index. A technological platform was used that allowed the measurement of the kinematics of their movements from the first stroke cycle until the end at a 200-metre distance. Results: With the use of inertial and magnetic sensors, a comparative study of the kayakers of the sample was carried out, verifying that the distance reached by the boat in every stroke is greater on the right side with a distance of 3.651 metres and the minimum on the left side with a distance of 0.762 centimetres. The smaller amount of strokes that were made in the 200-meter test was 81 strokes/minute and the best displacement average was 2.387 meters, data that allow the measurement of the speed, displacement of the boat and number of strokes, are the most important factors to obtain better marks in this sport discipline. Conclusions: The lack of preparation of the kayakers was demonstrated since the stroke cycle in the aerial and aquatic phases is deficient, as the paddle blade does not enter the water in its maximum amplitude and the fluctuation in the control of the rate are factors that generate a smaller displacement of the boat.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
