Research on Football 5-a-side for blind people is usually informative and does not often consider sports performance analysis. This study aimed to verify the existing differences between the 2014 World Championship of Fa5 and the 2016 Paralympic Games, analyzing the action for an effective game, the throws to the goal. For this purpose, a total of 52 matches were analyzed and the statistical analysis unit was all the throws made to the goal during the game (n = 2.227). A descriptive and differential analysis was made between the variables proposed in the study considering the type of competition. The results show the existence of differences between the championships, analyzed explicitly through the variables: Championship phases, Throwing moment, Match status, Starting zone, and Throwing result, as well as the variables Progression type, Throwing zone, Striking situation, Corporal zone, and Striking type. These results highlighted that teams played differently but also set game trends and styles for future competitions.

Quantitative Indicators

Experts in artistic gymnastics are constantly analyzing the outcomes of the gymnasts' performance at world and continental championships. However, the analyses cover only the assessment of the final scores of athletes and their ranks. There is a lack of research focused on the structure of routines and components of the scores obtained for the performance of combinations. The purpose of this study was to determine the content of competitive programs performed by the finalists of the World Championship Uneven Bars 2019 and to identify areas for the exercise development in this kind of all-around events on the eve of the Olympic Games. Methods and organization of the research: we carried out the analysis of video materials of the International Gymnastics Federation (FIG), the analysis of the competition rules for the current Olympic cycle, additional newsletters, and scientific instructional literature. We used an expert assessment method to identify the components of competitive combinations. Research results. The study determined quantitative indicators of the content of gymnast combinations on uneven bars (the number and difficulty groups of elements, including jumps and dismounts, modal and frequently performed elements, connection value bonus). We have revealed the trend for reduction of the total number of elements of competitive routines. It occurs due to reduction of the number of binders (“dilution”) elements, reduction of the number of elements of difficulty groups below 0.4 points, and increasing number of flight elements performed in a “cascade” way. We have revealed the trend for the use of elements of F (0.6 points) and G (0.7 points) difficulty groups in competitive combinations of the strongest gymnasts, which characterizes a significant increase in the coordination complexity of the programs and increases the requirements for the training of gymnasts. Conclusion. The research outcomes can provide the basis for predicting competitive programs on uneven bars at the upcoming Olympic Games, making amendments to the system of training gymnasts and the content of combinations to increase competitiveness at major international competitions, as well as making competition rules proposals for the next Olympic cycle.

This paper presents statistical analysis of delays in Integrated Communication and Control System (ICCS) networks [1–4] that are based on asynchronous time-division multiplexing. The models are obtained in closed form for analyzing control systems with randomly varying delays. The results of this research are applicable to ICCS design for complex dynamical processes like advanced aircraft and spacecraft, autonomous manufacturing plants, and chemical and processing plants.

UsingTCP(TransmissionControlProtocol)inwirelessnetworkscanaffectitsperformanceduetoits lack of ability to identify packets losses properly, causing the triggering of its congestion control mechanism. Some TCP variants were proposed to improve this control, being TCP-UEM one of them. This variant allows the evaluation of the link reliability in wireless networks in time intervals, keeping the end-to-end semantics. TCP-UEM was implemented in FreeBSD OS and its performance with relation to segment transfer rate (in Mbps) was compared to two other variants, TCP-NEWRENO and TCP-CUBIC. This paper describes TCP-UEM, discusses results of the tests and the statistical analysis that were carried out using two scenarios. For each scenario, 30 samples of 30 seconds of execution time with different loss rates were collected. The results showed that TCP-UEM presented a good performance, achieving a performance higher than the other two variants in the majority of the tests, with different loss rates.

Abstract The aim of this study was to describe the variations in power performance of elite Paralympic judo athletes across three consecutive training cycles of preparation for the ParaPan American Games, the World Championship and the Paralympic Games. Eleven Paralympic judokas from the Brazilian National team participated in this study. They were repeatedly assessed using squat and countermovement jumps, mean propulsive power (MPP) in the jump-squat (JS), the bench press and prone bench pull at several moments of the preparation. Training supervision based on the optimum power zone (range of loads where power production is maximized) was provided in the final cycle, prior to the Paralympic Games. Magnitude-based inference was used to compare the repeated measurements of power performance. Lower and upper limb muscle power gradually increased throughout the cycles; however, the best results in all exercises were observed prior to the Paralympic Games, during which the team won four silver medals. As an illustration, prior to participation in the Paralympic Games the MPP in the JS was likely to very likely higher than prior to the World Championship (effect size [ES] = 0.77) and ParaPan American Games (ES = 0.53), and in January and March 2016 (ES = 0.98 and 0.92, respectively; months preceding the Paralympic Games). Power performance assessments can provide information about the evolution of Paralympic judokas, and training at the optimum power zone seems to constitute an effective method to improve lower and upper limb power in these athletes.
