The third group of the XXXI Bulgarian Antarctic expedition in Livingston Island at the beginning of 2023 included participants from three fields – scientists, logisticians, and builders. Participants’ activities are greatly dependent on extreme environmental conditions. The aim of this study was to examine the sensation-seeking need, major stress factors, and preferred stress coping strategies of the participants in XXXI Bulgarian Antarctic expedition in Livingston Island. The research was done among 28 participants from XXXI Bulgarian Antarctic expedition, aged between 30 and 71 years. To fulfill the aim of the research, we used: 1) Methodology for researching psychic instability and sensation seeking, adapted by Velichkov & Radoslavova, 2005; 2) Coping Orientations to Problems Experienced scale – COPE – 1, Carver et al., 1989, adapted for Bulgarian conditions (Georgiev et al., 2003); 3) Methods for researching stress sources among participants in Antarctic expeditions. The results showed that the subscale functional impulsivity had the highest values. It was followed by the subscales of sensation seeking and dysfunctional impulsivity. The factor Interpersonal relationships and an abrupt change in the familiar environment had the highest values as a stress source. The emotional coping strategies were domineering, followed by the active coping strategy. The strategy of Cognitive and Emotional disengagement had the lowest values. There were significant differences from the results obtained from previous Bulgarian expeditions. The results can help adaptation and adequate prevention to decrease participants’ psychological stress.","PeriodicalId":34626,"journal":{"name":"Journal of Applied Sports Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41333104","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 aim of this study was to investigate the reliability and validity of various force-time indicators for the assessment of finger and shoulder girdle strength in climbing. Ten male lead climbers (climbing ability: advanced; IRCRA: 22 ± 2) performed two RFD and two maximal strength tests for the finger flexor and shoulder girdle muscles (one-arm finger hangs and lock-off s, respectively). The maximal strength tests were used to assess maximal force (Fmax). The RFD tests were used to assess: peak force (Fpeak); time for reaching force representing 25%, 50%, and 75% of the body weight (T25%BW, T50%BW, T75%BW); and absolute and relative RFD indicators (e.g., RFD at 200 ms and 95% Fpeak, respectively). The reliability of the finger flexor RFD indicators was high (intrasession intraclass correlation coefficients - ICC between .760 and .973; intersession ICC between .883 and .955). Intersession reliability of the finger flexor T50%BW and T75%BW reached excellent values (ICC = .949 and ICC = .978, respectively). Reliability of the finger flexor and lock-off Fpeak and Fmax was also high (ICC between .850 and .966). Consistency between Fpeak and Fmax was not satisfactory, though. These variables differed significantly (p = .035) in the finger flexor tests, and ICC was moderate (.605) in the lock-off tests. Most of the lock-off force-time indicators had moderate or poor reliability. Finger flexor and lock-off Fmax/kg and T50%BW correlated significantly (p < .05) with the climbing ability (R = .805, R = .653, and R = -.703, respectively), while lock-off force-time indicators did not. T50%BW was the most reliable and valid force-time indicator in advanced climbers. RFD indicators were reliable, but muscle strength appeared more important than RFD in advanced climbers.","PeriodicalId":34626,"journal":{"name":"Journal of Applied Sports Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41661499","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}

Virtual reality is frequently associated with entertainment for adolescents. This is not always the case, however. Military, medicine, education, and architecture could all benefit from virtual reality, and in these fi elds, with complete confidence, sports and physical activity could also be added. As the origins of virtual reality are examined, it could be confirmed that people have always desired to recreate reality, beginning with drawings and progressing through cinema and photography to modern technologies that attempt to recreate the environment, real objects, states, etc., as accurately as possible. This study aims to analyze the available and accessible literature that has examined the application of different types of virtual reality. In order to fulfill the set objective, access through the virtual library of SUNY Empire State College was used. The researched databases were ProQuest, MEDLINE (with Full Text), PloS ONE, JSTOR, Library and Information Science and Technology Abstracts with FullText, EBSCOhost, LearnTechLib, Sage Journals, and Science Direct. The PRISMA guidelines were utilized to guide the review’s conduct. The total number of sources studied was 2800, and through the PRISMA model, the final amount of analyzed articles was reduced to 11. According to the set inclusion and exclusion criteria, the articles considered comprehensively explained the methodology employed and delved into the effects of virtual reality on sports and physical activity among the participants. Virtual reality technology provides a personalized experience by adapting to the individual’s interests and abilities. It has been discovered that immersive VR exergames can result in the same or greater exercise intensity than conventional exercise conditions. Exergaming in virtual reality could be especially beneficial for promoting physical activity and overall societal health.","PeriodicalId":34626,"journal":{"name":"Journal of Applied Sports Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47278105","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}

These are initiated by a high amount of force produced by the lower limbs in a short amount of time. It is established in senior athletes that there is a relationship between lower-body maximum strength and swim start performance. The aim of this study was to investigate the relationship between lower-body maximum strength and swim start performance up to 5 and 15 m in elite youth swimmers. Twenty-two (10 females, 12 males) well-trained adolescent swimmers executed a one repetition maximum (1RM) back squat test, a counter movement jump (CMJ), a squat jump (SJ) test, and two trials of a swim start following a freestyle sprint up to 15 m. Bivariate Pearson correlation analyses were used to assess the relationship between strength and jumping performance and start performances up to 5 and 15 m. The level of significance was set at p < .05. Strength and jumping performance explained 55–73% of the variance in start performance up to 5 and 15 m. Strong correlations were found between resulting forces on the block and times to 5 and 15 m as well as between 1RM back squat test, CMJ, and SJ and times to 5 and 15 m (all between r = –.75 and r = –.86; p < .01). This study demonstrates that strength parameters of the lower limbs affect jumping performance off the block in swimming. Therefore, these parameters are usable predictor variables in assessing start performance up to 5 and 15 m in swimmers.","PeriodicalId":34626,"journal":{"name":"Journal of Applied Sports Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43472113","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}

If in other competitions, the result of the athlete is clearly monitored by a stopwatch, here the judges give marks for the performance. Judges are people who can be biased in judging or simply can make mistakes. 2002 was a turning point in figure skating judging. After the 2002 Salt Lake City USA Winter Olympics scandal, the so-called six-zero scoring system was replaced by a new judging system. The purpose of the research is to analyze the judges’ scores and dependencies between the final result and the separate segments of the evaluation when the ISU judging system was introduced in 2004. In order to achieve the set goal, the judging protocols of the Winter Olympic Games in women’s figure skating were studied after the introduction of the ISU judging system in 2004. After the introduction of the ISU judging system, the evaluation of the programs has become much more precise, where each element is evaluated separately. Expanding the scale for evaluating technical elements from -5 to +5 after the Winter Olympic games in 2018, according to the analyses carried out, leads to a greater weighting of the judging panel, which consists of 9 judges, rather than the technical panel, consisting of 3 specialists. This could ultimately lead to more objective judging in figure skating.","PeriodicalId":34626,"journal":{"name":"Journal of Applied Sports Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44230265","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 aim of this study was to determine the level of development of the physical ability of students in 5th and 6th grade, through analysis and evaluation, according to the new regulatory system for evaluation. The research was carried out with 75 pupils at a secondary school in the city of Sofi a. To realize it, we used a test battery that carries information about the significant indexes of physical fitness. The battery includes five tests: running 30 m., standing long jump with both feet, 3 kg medicine ball throwing with both hands from a standing position, running 200 m., and agility and spatial coordination test. The testing and mathematical-statistical methods (variation analysis comparative analysis with t-criterion of Student and sigma evaluation method) were used in our study. The analysis of the results showed that there was a statistically significant difference between the students from 5th and 6th grade, only in terms of the indicator of agility and spatial coordination. Such a difference was found in the same test, by gender and age, among the boys from the two study groups.
