In the last five years, many companies have tried to make this measurement both easy to perform and very practical for coaches. In this study, 10 elite swimmers aged between 12 and 14 years were observed for 21 days. All swimmers were ranked in the first two places at the Romanian National Championships in at least one swimming event. In this period, they performed three speed tests at a 10-day interval. The speed test consisted of four repetitions of 50-meter freestyle, with a rest period of 5 minutes. Heart rate variability was measured every morning on the swimming deck just before practice. For this measurement, a very easy-to-use device was used, namely ithlete Finger Sensor, a photoplethysmography that was attached to a mobile phone and, after 55 seconds of measurement, the device provided an easy-to-interpret value. The relationship between heart rate variability measurements and swimming speed was interpreted. It was demonstrated that the results obtained for heart rate variability influenced the swimming speed results with a p-value < 0.001. This is one of the first studies to focus on how speed will depend on the measurement of heart rate variability just before the training session. For this reason, we cannot compare our results with those obtained in other studies. The current study also has some limitations, and one of the most important is the small number of participants.","PeriodicalId":31352,"journal":{"name":"Discobolul Physical Education Sports and Kinetotherapy Journal","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84905096","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to analyse the scientific literature in order to find the most effective training methods for the development of speed in fencing. Google Scholar, PubMed and Web of Science databases were accessed with the purpose of finding original research studies focused on developing different forms of speed in fencing for any technical element of this sport, which were written in English, Romanian or Hungarian and were accessible in full text. Finally, 16 articles were included in the study. The types of training that led to improved fencing speed were: eccentric and plyometric training, strength training, core strength training, speed training, agility training, instability resistance training, fitness training, circuit training, ballistic and dynamic stretch training (during warm-up), functional training, bilateral transfer training, SAQ (speed, agility, quickness) training. These types of training were applied to foil, sabre and épée fencers of both genders, from various age groups and with different levels of training over periods between 1 and 12 months. To date, the exclusive superiority of one method has not been explicitly proven. In conclusion, it can be argued that several types of training can develop different forms of fencing speed, especially reaction and execution speed, which helps to achieve better performance in this sport.","PeriodicalId":31352,"journal":{"name":"Discobolul Physical Education Sports and Kinetotherapy Journal","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85230147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methods used to conduct this study were the following: bibliographic documentation, direct and indirect observation, testing and measurement, graphical method. In this research, the Polar M400 Heart Rate Monitor was used during the 14 weeks of training. Each girl athlete has her own device (watch and chest belt) and own Polar Flow account where data are transferred from the watch. The software allowed us to record data during the physical training and tennis training of athletes, as well as their daily activity expressed as a percentage. The assessments of tested parameters highlighted the following: the 50-minutes run at a pace of 150 beats per minute (bpm) recorded an average increase of 1.3 km, with a percentage increase of 19.78%; basal heart rate recorded an average decrease of 14.3 bpm, with a percentage increase of 18.14%; VO2 max recorded an average increase of 6 ml/kg/min, with a percentage increase of 10.81%.

The research purpose is to identify the development level of some skills/components that condition the execution of Body Difficulties in the group of Jumps/Leaps according to the requirements of the FIG Code of Points and increase the value of technical elements in competition routines. The research was conducted on 14\u0000rhythmic gymnasts, members of the National Junior Team of Romania, and included two stages as follows: the first test took place in December 2019, and the second, in August 2020. Motor and biomechanical information was collected to objectify some motor skills involved in the performance of technical elements specific to the group of Jumps/Leaps. Muscle power, contact times, jump height, flight times and jump rhythm were assessed\u0000using the Microgate OptoJump Next device, and the duration of technical elements in the group of Jumps/Leaps was measured by a stopwatch. A programme for the improvement and consolidation of technical elements belonging to this group was applied during the research. Statistical analysis of the collected data required checking the normal distribution of results (using the Skewness and Kurtosis coefficients), identifying the mean differences between the two tests by applying the Student’s t-Test and identifying correlations between the parameters resulting from the two tests using Pearson’s correlation coefficients. Analysing the correlations between the investigated variables for both lower limbs, it can be stated that there is clear evidence of the\u0000dependency links between the two symmetrical segments as well as positive and negative correlations between OptoJump variables and the average duration of jumps.","PeriodicalId":31352,"journal":{"name":"Discobolul Physical Education Sports and Kinetotherapy Journal","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74950856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anxiety represents a multifaceted response that can hinder or help performance. Anxiety experienced at high intensity and in the long term is a noxious phenomenon. However, moderate anxiety can lead to improved performance, stimulating on-task effort. The aims of our study are to determine the pattern of\u0000anxious reactions in coaches with superior results in competition and to identify which facet of anxiety is a better predictor of sports performance. A total of 57 coaches (19 women and 38 men) participated in the research. We assessed four facets of trait anxiety using the Endler Multidimensional Anxiety Scales. The results highlight significantly lower scores in successful coaches compared to novice coaches for anxiety in new situations and in separation conditions. When talking about anxiety in physically dangerous and sociallyevaluative circumstances, no significant differences were found between the two groups of coaches (successful and beginner ones). After performing two separate binomial logistic regressions, we can argue that the scores\u0000for anxiety in separation conditions are a better predictor of sports performance than anxiety in new situations, the model explaining 30% of the variance in international or national performance and correctly classifying 75.4% of cases. The conclusions of our study represent valuable resources for sports psychologists, future (and current) coaches and researchers who are eager to better understand the impact of A-trait on sports performance, in the case of coaches.","PeriodicalId":31352,"journal":{"name":"Discobolul Physical Education Sports and Kinetotherapy Journal","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85081616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dryland training is an important part of any competitive swimmer’s programme. However, this non-specific training is usually neglected in prepubertal swimmers, its importance being recognised more often in junior and senior swimmers. This paper is a case study regarding the beneficial effects that a well-developed\u0000and suitable dryland training programme can have on a prepubertal swimmer’s results. The participant in this case study was a Romanian male swimmer born in 2010, who got the highest score at the National Championships in 2020. The detailed dryland programme (developed by the author of the current study) was followed by the athlete for a period of 7 months. The implementation of this programme took place between two national championships (October 2020 - June 2021). The specific objectives were: winning the title of national champion in 50-meter butterfly and making a progress of 2 seconds; ranking among the top three swimmers in 100-meter freestyle and making a progress of 4 seconds. After applying the programme, the athlete made a progress of 2.57 seconds and won first place in 50-meter butterfly. In 100-meter freestyle, he made a progress of 6.34 seconds and won second place.

It will be taken into account that the topicality of this paper “depends” on the positive law in the matter, and we refer here to the regulations regarding the deontology of the coaching profession, whose non-violation can partially provide us with the basics of practising clean sports. The legal and legislative factors should consider the management of the institutions in charge of physical education and sport as very important. The training of “sports workers” as well as the\u0000management of specialised structures in a society undergoing an intense process of transformation, with a development perspective, requires a kind of training that includes modern general culture and specific knowledge but also legal training.
