Research aim was to analyse the perceptions of benefits and barriers of physical activity in physically inactive adults.Methods. Research methods were individual interviews and qualitative content analysis.Results. Insufficiently physically active adults have many different health and emotional problems, but this is not a sufficient motive for them to be physically active. Research participants positively evaluated the benefits of physical activity if their physical activity did not exceed their physical fitness; however, it was not optimal and did not comply with the proposed minimum recommendations. Physical activities of adults were mostly related to holidays, cooking, playing with children, and activities in nature. Meanwhile, respondents were more physically inactive – working at home, reading books, and spending time on smart devices. Adults mentioned more reasons to be physically passive than active. Internal causes of physical inactivity were related to lack of time, lack of motivation, antipathy to sport, health problems and internal beliefs, external causes – workload, weather conditions, financial situation, family and household.Conclusions. Physical health problems and psychological ailments of inactive adults were frequent consequences of physical inactivity. Their activities after work were passive (working at home, reading books and time on smart devices) and active (holidays, cooking, playing games with children, activities in nature). Although there were more active activities, most of them were in leisure time and they did not fully meet the minimum recommendations. The participants positively evaluated the benefits of physical activity if their physical activity did not exceed their physical fitness. Internal causes of physical inactivity of the participants were lack of time, lack of motivation, antipathy for sport, health problems, feeling of loneliness and age, external causes – workload, weather conditions, financial situation, family and household.","PeriodicalId":409740,"journal":{"name":"Baltic Journal of Sport and Health Sciences","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134558905","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}

Research aimed at the analysis of self-perceptions of students of foreign language anxiety in the classroom context in relation to its effect on foreign language acquisition. It focused on foreign language, as a skill needed for versatile education, which would lead to a successful career in sports or would aid in pursuing health enhancing leisure activities later in life.\u0000\u0000Methods. The qualitative approach of research was adopted in this study. Twenty subjects involved in the study programs as Sports Coaching at the Lithuanian Sports University and Medicine at the University of Health Sciences participated in the research. A semi-structured interview was conducted by the researchers based on 10 open-ended questions about foreign language anxiety.\u0000\u0000Results. Although the perceptions of students’ own English language competence were found to be an important source of anxiety for the interviewed students, most of the respondents perceive the necessity of trying to cope with stress and anxiety themselves. In addition, instructors appeared to be creating the feeling of relaxation rather than being the anxiety-provoking ones in the classroom.\u0000\u0000Conclusion. Awareness of the fact that FLA really exists and appears to be an obstacle for students’ academic achievement needs to be acknowledged. To address this issue, collaboration rather than competition must be implemented as a tool in classes for further advancement in learning. Therefore, these measures might help to reinforce self-esteem and achieve better results in the foreign language classroom and, thus, in the overall goal of studies in the student learning process.","PeriodicalId":409740,"journal":{"name":"Baltic Journal of Sport and Health Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129034498","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}

One of the most important problems for players, coaches and scientists is improving the accuracy of shooting the basket. It is the most important technique for playing basketball, and its dependence on performance is multifaceted.\u0000\u0000Methods. All 37 games in the 2015 European Championships in U16, U18, U20 and men’s national team were analyzed. Data was selected from the official boxscores of FIBA (International Basketball Federation). The following absolute game-related statistics were gathered: free-throws, 2-point and 3-point field goals (both successful and unsuccessful). The obtained values of the rate of success of 2-point, 3-point and free throw shooting were tested by the non-parametric Mann–Whitney U-test. The statistical analyses were performed using SPSS for Windows, version 20.0, and statistical significance was set at p < .05.\u0000\u0000Results. Comparing the number and accuracy of shots taken from 2-point distance, we found that there was no significant difference between men of different ages (p > .05). Most 3-point shots were done by U16 youth team, the least was in men’s national basketball team, a significant difference in the indicators (p < .05) was found between all the teams, except between men’s national team and U18 (p > .05). Comparing free-throws’ indicators between different age groups, most throws were done by U16 team, the least were done by the U20 team (p < .05); however, there were no differences between the other significant indicators (p > .05). Comparing free-throws accuracy indicators between the different age groups of basketball teams, significant differences in indicators were found between men’s national basketball team and U20, U16 (p < .05).\u0000\u0000Conclusions. The count of 2-point shots made in Lithuanian different age basketball national team games was more or less similar. Most 3-point shots were made by U16 team and the national men’s team made least 3-pointers. The indicators of accuracy did not have a significant difference between national teams, except for free throws: men’s national team made these shots most accurately, opposite situation was with U16 team.","PeriodicalId":409740,"journal":{"name":"Baltic Journal of Sport and Health Sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131394041","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}

Activities like running, push-ups and sit-ups may be impacted by a higher body volume and size whether it is due to the amount of fat mass (FM) or skeletal muscle mass (SMM). The purpose of this study was to investigate the differences in physical performance among muscularly developed police employees with higher body mass index (BMI) levels. Methods. Twenty (n = 20) male police employees were divided in 3 groups by BMI but defined by significantly different skeletal muscle mass index (SMMI): muscular (n = 7, BMI < 25 kg/m2, SMMI ≥ 13.16 kg/m2), very muscular (n = 7, BMI = 25–27.5 kg/m2, SMMI = 13.17–14.10 kg/m2), and highly muscular (n = 6, BMI > 27.5 kg/m2, SMMI ≥ 14.10 kg/m2). Body composition components (FM, SMM, percent of fat mass [PFM], percent of skeletal muscle mass [PSMM], SMMI) were assessed by multichannel bioelectrical impedance. The differences in performance of the 50-meter sprint run (RU50), 1-minute push-up (PU), 1-minute sit-up (SU), and 800-meter run (RU800) between BMI groups were statistically tested by a univariate analysis of variance with a Bonferroni post-hoc test. Results. Highly muscular participants performed fewer SU than muscular (8.14 repetitions, p = .004) and very muscular (6.42 repetitions, p = .021) participants, and run slower on RU800 test (52.57 s, p = .034 and 51.71 s, p = .038, respectively).

Mokymo ir auklėjimo procesuose svarbiausias ugdymo(si) instrumentas yra mokytojo asmenybė. Asmeninės žmogaus savybės visuomenėje yra vertinamos tos, kurios parodo orumo realizavimą elgesyje ir santykiuose, t. y. dorovinės vertybės, kurių pagrindu reiškiasi orumas.Tyrimo probleminis klausimas: kokie mokytojo asmenybės bruožai ir ugdymo procese atliekami vaidmenys yra susiję su paauglių orumo ugdymu bei ugdymusi? Probleminis klausimas neatsiejamas nuo tyrimo objekto — ryšio tarp mokytojo atliekamų vaidmenų ir paauglių orumo ugdymosi.
