We aim to emphasize the usefulness and efficiency of the use of the electronic training monitoring system SUUNTO, in evaluating the specific effort of training and competition in the test - Skeet 125 men's plates. Used for the first time in sports shooting in Romania, during the training of athlete Alin George Moldoveanu, Olympic champion London 2012, in the men's 10m compressed air rifle, in the competition year 2011-2012, the electronic monitoring system SUUNTO proved its usefulness practice, determining us to continue and extend our scientific approach to the level of another test specific to sports shooting. As a physical trainer of the athlete Ghetu Vlad, multiple national champion in this event, being currently a member of the Youth Olympic Team, with real chances of qualifying for the Tokyo 2021 Olympics, we decided to implement this means of evaluation, in order to increase planning efficiency. and scheduling specific effort.Through the feedback it offers, translated into the values of the monitored internal parameters, respectively, heart rate, respiratory rate, the SUUNTO electronic system offers an objective image on the dynamics of the specific effort of the analyzed sample, constituting a solid benchmark in sports training according requirements imposed at the level of performance sports shooting. The information obtained from the monitoring can be viewed and downloaded through the website www.movescont.com, the data being analyzed and interpreted by both authors of this paper. The analysis of the results obtained in this research will be the basis for the realization of some physical training programs, adapted to the requirements of the training process, the competitive effort and, last but not least, to the particularities of the athlete involved.

Triboelectric Nanogenerators (TENG) in field of wearable human motion sensors has shown significant potential in biomedical monitoring and athlete posture sensing which requires the proper power management circuit. Hence the idea of scavenging the biomechanical energy would minimise this issue thereby giving a new insight towards self-powered devices. We propose a flexible, wearable Kinesio tape based triboelectric nanogeneartor (KT-TENG) which converts the biomechanical energy of knee joints to electrical energy that is further programmed to monitor the athlete’s motion. This works on contact and separation mode where Ecoflex and copper are the negative and positive tribolelectric layers of KT-TENG which is fabricated using a cost-effective approach. The device generates a maximum voltage of ~5V and ~1μA of current respectively. The performance analysis proves that KT-TENG has the potential to contribute towards the energy conversion process providing original intended benefits to athletes. [ABSTRACT FROM AUTHOR]

The aims of this study are: to modify dysfunctional negative emotions during competition, by using mental training techniques. Improving behavior of athletes is possible by reducing stress and anxiety. Problem Statement: first testing took place during 05-06.02.2015, subjects aged between 12 ± 6 and 17 ± years, consisting of 15 athletes both in group I and the group II, mean age of 15.05 for subjects in group I and 15.49 for subjects in group II. Second testing took place in February 2016, same period. Purpose of Study: the experimental series comprised 20 skiers, from the club CSS Vatra - Dornei (SV) - control group and CSS Baia - Sprie (MM) - experimental group. General aims in conducting the research were to develop a strategy that can reduce stress and anxiety during competition. We worked with athletes that had to learn relaxation techniques, mental and physical. To determine mental training, we have applied specific techniques, that influence certain psychological factors to optimize performance in biathlon skiing. Methods: we used a device EmWave2, which is a biofeedback. It gives us information about physiological indicators such as heart rate. EmWave technology is based on the discovery of consistency. Coherence is a state of synchronization between the heart, brain and autonomic nervous system. By practicing condition of consistency throughout the body it can relieve stress, can heal emotional trauma, exaggerated worry and fear, and as it is practiced, there is an improvement in increasingly greater overall health. Findings and Results: using this tool we succeed in improving the general health of the athletes, we've optimized the performance capability by increasing the speed of learning and the power of concentration, achieving a higher level of emotional balance. To test the normal distribution the Shapiro-Wilk test was used. For data with normal distribution we have used the t test (Student) and to calculate uneven distribution or nonparametric ranks we used, Mann-Whitney (U) test for two unpaired samples or Wilcoxon for two pairs samples. For the analysis of three or more samples ANOVA test was used for normally distributed data or the non-parametric Kruskal-Wallis test, in the case of an uneven distribution of values or rank. Statistical analysis values of EmWave2 test, considering the three levels of consistency was observed: in group I - statistically highly significant differences between at least two levels (p <0.01). In group II - intense statistically significant differences between at least two levels (p <0.001). In experimental group we have observed- statistically highly significant differences between the levels of LH, MH (p <0.01) and in control group - statistically highly significant differences between the levels of LH, MH (p <0.01). Conclusions and Recommendations: The comparative analysis of test scores applied to the studied groups and statistical significance we can say that by applying mental training it leads to lower anxiety technique issues. In statistical analysis of the EmWave2 test were not observed statistically significant differences between the two groups (p> 0.05). Concerning mean heart rate (FC average) recorded by EmWave2 test, statistical intensely significant differences were observed between the two groups (p <0.001). The statistical analysis of time values by using EmWave2 test, were highly significant, between the two groups (p <0.01). [ABSTRACT FROM AUTHOR]

KinectX (KX) and KinectX Pro (KXP) are two specific applications for the training and evaluation of precision in body motion coordination. KinectX Pro was designed to provide an evaluation of efficiency of Ultra Slow Motion Intelligent Training (USMIT) for precision in motor coordination. KinectX was designed to provide direct feedback during the USMIT training in order to know the proper constant speed in ultra slow motions (10 mm/s). Material and method. 142 voluntary subjects participated in four sets of trials (a total of 657 tests): (1) preliminary tests (N=8); (2) motor coordination and psychological trait correlation tests (N=100); (3) precision progress in motor coordination tests (N=8); (4) motor coordination tests (N=27). Five advantages of KX and KXP were identified: (1) "no strings" movement; (2) "live" speed feedback; (3) trajectory feedback; (4) good sensor sensitivity (up to 30 evaluations per second); (5) easy relocation of KX and KXP systems. Two major disadvantages were identified and corrected during testing: (1) high sensitivityto light intensity variations; (2) high sensitivityto infrared radiations. One minor disadvantage: (1) variations inthe test results with variations in the subject's position vs. sensor. Results. A guide for the optimal use of both applications was completed, tested and used in the trials. A beta version was completed for both KX and KXP and successfully used in the trials andthe training of athletes, members of the Romanian Olympic Team 2018. Conclusion. KinectX and KinectX Pro are reliable instruments in the training and evaluation of precision in motor coordination, based on the USMIT program. [ABSTRACT FROM AUTHOR]

Introduction: Anaerobic power is an important factor determining physical performance in competitive sports. The aim of this paper is to analyze the anaerobic power of athletes involved in various competitive sports which require different forms of training, and to describe the effect of each group's specialized training over a period of one year on the anaerobic indicators defined by the 30 second Wingate test. Method: The study involved 15 soccer players (SP), 12 practitioners of martial arts (MA), 15 weightlifters (WL), 12 athletics runners (AR), and 12 race walkers (RW). Each group of athletes was of a broadly similar age and level of accomplishment. Anaerobic power was determined using the 30 second Wingate test before and after the one-year period of specialized training. Results: The parameters of total external work (Wt) and mean power (Pmean) did not vary between the groups in a statistically significant way, while maximal power output (Pmax) and fatigue index FI differed. Pmax had increased in group AR and RW as the effect of one-year training. Conclusions: An almost identical level of development was found in anaerobic power but the causative factors were different in the various groups. Only to a limited extent was the one-year specialized training an adequate stimulus for the development of anaerobic power. [ABSTRACT FROM AUTHOR]

The high degree of applicability of various software in high performance athlete training, allows for a more detailed analysis of any technical aspects. It also underlines any deviations, thus improving execution through the addition of specific restructured means. Any trainer whom owns a current generation smart-phone or tablet may download an application known as Coach's Eye for a modest sum. Keeping in mind one must be able with one's fingers, the software may be employed in order to underline various flaws in technique that may appear throughout a certain event. These errors may be addressed at a later time by applying more or less conventional means. This paper contains a sequential technique analysis, accomplished with the Coach's Eye software, for one of the most highly rated javelin throwers of Romania. The athlete's level of performance (78.90m), requires specialized technique assistance which in turn means repeated video footage analysis. To this end several videos were created of events that occurred in the 2012 competitive period. With the help of the Coach's Eye software, various video frames of technical importance were acquired, of the moments prior and after release. The resulting biomechanical analysis of the athlete's movements covered the period prior to and after technical corrections were made during consecutive competitive years. The conclusion we reached was that in spite of existing software limitations, the use of various applications equates to a step forward concerning proper technique assimilation as early as the event specialization period. At the same time the use of such software is an important approach regarding high performance athlete training. While in the learning and consolidation period, observing and analysing video footage of various executed exercises allows us to track errors more efficiently and stop them before becoming an automatic feature for the athlete through careful application of corrective exercises.

Sports in general are conditioned by effort management during training. High performance athletics even more so. Certain means and trials that closely simulate event conditions are employed. This helps conserve the athlete's energy and speeds up healing implicitly. By using a data management program (SPSS - Statistical Package for the Social Sciences), we will be able to outline tendencies, generate charts and tabulated reports in order to achieve a better prediction for performance during events, based on relevant trials. The subjects of our research were 25 athletic throwers (javelin, shot put, discus), that were part of the group representing Romania. Events held about 3 weeks prior to any major competition were taken into account, and by using advanced analysis means, the SPSS application managed to calculate the correlation parameter between results achieved then and during the closest competition, while underlining the predictive value of such data. After data processing, statistical but not causal dependencies were found between certain trials and the throwing distance achieved during the closest competition, thus arguing the fact that some tests are simply not significant for the predictive pattern. In certain situations, the utility of the various preparation trials with regards to the athletic event is not more significant than correctly ascertaining the athlete's training level, state of being (fatigue or preparation), predicting the rate of progress for effort capacity, limiting in order to prevent injury as well as preparation to achieve a sportive form. In conclusion, the SPSS application, while underlining the usefulness of trials for a predictive pattern, may be considered a valid instrument for measuring future performance, only when the other factors are not detrimental to it.

Results of the luge athletes strongly depend on the successful start. While number of methods successfully analysed movements around start handles, still there is lack of methods to monitor paddling strokes. Present paper demonstrates smart textile gloves, designed for such a purpose. Developed gloves allow to measure timing of the arms strokes as well as easily distinguish between good stroke, when athlete's palms are in full contact with ice, and insufficient one, when fingers just slide over ice without providing good push.
