Healthy lifestyle skills instilled in childhood remain into adulthood. Parental physical activity skills are directly related to their children’s physical activity which strengthens their children’s physical fitness. The aim of the study was to determine and evaluate the relationship between parents’ and children’s physical activity and to evaluate the links between children’s physical activity and physical fitness.Methods. The study involved 486 primary school children aged 7 to 10 years (240 boys and 241 girls) and their parents from Kaunas district. The study was conducted in 2018 in Kaunas district schools. Parental physical activity was assessed using Godin Leisure-Time Exercise Questionnaire-GLTEQ (Godin & Shephard, 1985). Physical activity of primary school children was assessed by submitting a questionnaire to parents developed by researchers Bacardi-Gascón, Reveles-Roy, Woodward-Lopez, Crawford, and Jiménez-Cruz (2012). Schoolchildren’s physical fitness was assessed by 9 physical fitness tests (Fjørtoft, Pedersen, Sigmundsson, & Vereijken, 2011).Results. Having assessed the physical activity of children according to WHO (2010) recommendations, we found that the vast majority of the surveyed children (93.6% of boys and 86.3 of girls) were physically active, i.e. they engaged in physical activity for more than 1 hour during the day. Comparing the schoolchildren’s physical fitness by gender we found that boys were more physically fit than girls when performing long jumps, two-legged jumps, throwing a tennis ball, and running for six minutes (p < .05). Comparing the results of schoolchildren’s physical fitness by grades (Table 3), we observed that the older children were, the more physically fit they were. Correlation analysis of the research results showed a statistically significant direct relationship between father’s and mother’s physical activity (r = .487, p = .0001). A significant relationship was found between the results of children’s physical activity and tennis ball throwing (r = .170, p = .018) and the results of 10 * 5m running tests (r = –.150, p = .019). Higher physical activity was directly associated with better scores on these tests.Conclusion. Schoolchildren’s and their parents’ physical activity has no relation with schoolchildren’s physical fitness.Keywords: healthy, lifestyle, physical activity, physical fitness.","PeriodicalId":409740,"journal":{"name":"Baltic Journal of Sport and Health Sciences","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116984656","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 drive for muscularity in men is associated with a negative body image, psychosocial, and physiological outcomes. The aim of the present study was to test the psychometric properties of the Lithuanian version of the Drive for Muscularity Scale (DMS-LT) and associated characteristics in the sample of young adults (men). Methods. The sample consisted of 763 male students. The ages ranged from 18 to 32 years, with a mean age of 20.4 ( SD = 3.1). Participants completed the Lithuanian translation of DMS-LT alongside with the measures of disordered eating, sociocultural attitudes towards appearance questionnaire, body mass index, self-esteem, and participation in sports. Results. The instrument showed good internal consistency (Cronbach’s alpha = .92) and test-retest reliability ( ICC = .87). The two-dimensional factor structure of the proposed original scale was not confirmed. DMS-LT was negatively correlated with self-esteem. Positive associations were observed between DMS-LT, muscular/athletic body ideal internalization, and disordered eating. Drive for muscularity attitudes and behaviors were more expressed in male students attending sports clubs. Conclusions. The results of the present study support the psychometric properties of the DMS-LT and its’ use in Lithuanian samples of young men. The instrument might also be used in clinical practice. It is important to develop prevention programs that decrease body image concerns and prevent disordered eating in young men.

Constantly accelerating pace of life, heavy workloads, and new technologies coming into our lives lead to mental health problems - stress, anxiety, and depression, which causes uncontrollable physical health problems. The relationship between individual PA domains and physical activity intensity in middle-aged individuals as well as their psycho-emotional status have not been sufficiently explored. The aim of the study was to determine the relationship between psycho-emotional state and physical activity levels in middle-aged people. Methods. The epidemiological method was chosen for the study. The chosen method of data collection was an anonymous questionnaire survey. Results. Assessing the psycho-emotional state of the subjects, we found that 17.8% of women and men studied were experiencing stress. More women (45%) than men (27.5%) experienced nervous tension, and more men (25.5%) than women (13.7%) experienced stress. High levels of physical activity were found in more than 2/3 of the subjects (73.5%). The distributions of women and men did not differ much according to the level of physical activity (74.3, 72.0%). Conclusion. A higher level of physical activity was associated with a better assessment of nervous tension and stress – more physically active individuals experience less nervous tension and stress. People who spent more time sitting on weekdays and at weekends experienced more nervous tension and stress.

Basketball coaches need to find or create an effective training program while developing and training mini-basketball players. Only an effective and certified training program can help optimize the training process and bring success. So our aim of the analysis was also to determine and evaluate the effectivity of different training programs for mini-basketball players (8–9 years old). Methods. The study included ( n = 38) mini-basketball (aged 8.5 ± 0.27 years) players. During the study, the subjects were split into three separate groups of training programs (universal, technical, integral). Groups were formed in random order, based on their place of residence. Mini-basketball players of different training programs were tested before and after the study, which lasted for 4 months (17 weeks) during the competitive period. Results. The analysis of the results showed that the indicators increased the most after applying the Universal Training Program (UTP). After applying the UTP for 4 months, the indicators of speed increased by 1.9% and agility by 4.99% ( p < .05), however, speed-strength increased by 4.64% and endurance by – 5.64% when applying the Technical Training Program (TTP). The most time in TTP was spent developing skills (30.7%), but all of the indicators of technical skills increased, in UTP 20.3% of all the training time was spent on technical fitness. The indicators of dribbling (control dribble test) in the Universal Training Programme increased by 10.91% ( p < .05), (20m basketball dribbling test) by 3.7% (p < .05), shooting by 21.06% ( p  < .05).

Monitoring the abilities of typically developed children is very important.Methods. This study aimed to determine the levels and differences in motor coordination of the upper extremities between first and third-grade primary school children using the subtest of the Bruininks-Oseretsky Test (BOT-2). The sample included 79 healthy subjects of both sexes, chronological age ranging from seven to nine years, body height 134.51 ± 8.43 cm (Mean ± SD), bodyweight 33.01 ± 8.65 kg (Mean ± SD). The Mann–Whitney U test determined differences between groups, for the benefit of the group of third-grade subjects in all upper extremity coordination variables.Results. The results showed that differences in age and biological growth and development in young children in some variables of upper-limb coordination influenced medium size (2ULC, 6ULC, 7ULC), but in most of the variables examined they had great influence (1ULC. 3ULC, 4ULC, 5ULC, TULC) according to Cohen’s criterion.Conclusion. It can be concluded that well-organized and expertly guided physical activities, as well as regular testing of children when it comes to developing coordination, can influence early detection of movement difficulties and eliminate problems in acquiring new coordination skills, and thus create an appropriate base for engaging in sports activities while growing up. Keywords: motor development, coordination, physical education.","PeriodicalId":409740,"journal":{"name":"Baltic Journal of Sport and Health Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115091640","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 behaviour of physical education (PE) teachers in managing the lesson is significantly related to their life satisfaction (Bahadir, 2013). PE teachers’ self-report of emotional abilities is positively associated with the educational achievements of their students and increasing teachers’ self-report of emotional abilities improves the quality of physical education (Buns & Thomas, 2016). High self-report of emotional abilities reduces the impact of work-related stress on teachers, increases their creativity in classroom activities and increases students' satisfaction with physical activities (Huang, Liu, Hsieh, & Chang, 2015). The aim of this study was to evaluate physical education teachers’ self-report of emotional abilities and subjective quality of life in comparison with teachers of other subjects, so that in the future more effective measures for improving teachers’ self-report of emotional abilities and subjective quality of life could be developed.Methods. To collect data, Schutte SSRI and SF-36 questionnaire survey was applied.Results. We found that, according to some sub-scales, men and women were significantly (p < .05) different in the estimation of their subjective quality of life. Women scored better (higher scores) than men in their physical performance, emotional state, energy/fatigue, and perceived pain.  In this study, we revealed significant correlations between social skills and appraisal (r = .305, p < .01), emotional well-being and appraisal (r = .214; p < .05), and energy/fatigue and appraisal (r = .209; p < .05).

Everyday medical residents experience stress related to academic, professional, and personal factors (Alosaimi, Alghamdi, Aladwani, Kazim, & Almufleh, 2016; Dave, Parikh, Vankar, & Valipay, 2018), therefore it is important to take care of their psychosocial well-being. Traits of medical residents that are important for well-being are related to control of emotional information, and abilities that provide for effective handling of stressful situations are important as well. The objective of the present study was to assess correlations between emotional intelligence and stress coping strategies of medical residents.   Methods. The study sample consisted of medical residents (n = 108). The following questionnaires were used: TEIQue-SF and Coping Styles Questionnaire. Questionnaires were sent to personal electronic addresses and target groups of social networks. Paper-based questionnaires were presented in the work and gathering places of subjects.Results. Emotional intelligence was higher than average, and the most expressed trait was the overall sense of well-being (in relation to emotionality, self-control and sociability). Sociability and self-control were more expressed in men than in women.

Studies of various scholars confirm the relation between the application of stress coping strategies and emotional intelligence, but there is a lack of research about the relationship between individual coping strategies and emotional intelligence levels among the first- and the fourth-year students. The aim of the research was to reveal peculiarities of emotional intelligence and stress coping strategies of undergraduate students of physical education and sport study programs.Methods. The Shutte Self-Assessment Questionnaire was used to measure the level of emotional intelligence of the participants (Schutte & Malouff, 1999). The questionnaire composed by Grakauskas and Valickas (2006) was used to identify the stress coping strategies. It consists of four factors: social support factor, problem-solving factor, emotional discharge factor and avoidance factor. The research was based on the following ethical principles: confidentiality, anonymity, impartiality and privacy. The first- and the fourth-year students of the Lithuanian Sports University and Lithuanian University of Educational Sciences, Physical Education and Sports Programs were surveyed. The research sample consisted of 123 participants. Male participants comprised 66.7% of the sample, and the female participants comprised 33.3%. of the sample. The first-year undergraduates made up 57.7% of the sample, and the fourth-year undergraduates made up 42.3% of the sample.Results. Analyzing the data on the stress coping strategies according to the participants studying experience, it was found that the fourth-year students used the social support strategy more frequently in comparison with the first-year students.

Over the past decade, there has been an increase in scholars’ attention to moral behaviour in sport. Recently more studies have been dealing with cheating with a special focus on doping. The aim of this study was to provide an overview of research focusing on cheating in sport. Specifically, the purpose was to critically analyse research on personal and social factors which have been associated with an intension to cheat and cheating behaviour. Methods. Scientific research analysis on social environment factors related with cheating was carried out by focusing on personal and social environmental factors related with athletes’ attitudes towards, intention and cheating behaviours. Results. Moral identity is an important factor for cheating in sport and intention to use doping. A negative relation was found between moral values of athletes and doping likelihood. Also, when athletes perceive their goal only as winning the game (goal-oriented rather than task-oriented), they are more likely to cheat. Furthermore, recent studies have found the relationship between the Dark Triad (Machiavellianism, narcissism, and psychopathy) and the use of doping in sport. Moreover, perfectionism involves positive attitudes towards doping and actual use of doping. Also, there is evidence that moral values relate with athletes’ cheating and gamesmanship. Some social environment factors related with motivational climate created by the coach and parents. Coaches and parents created an ego-oriented climate associated with young athletes’ positive attitudes towards cheating. Conclusion . Athlete’s intention to cheat or actual behaviour is determined by both athlete’s personality and social environment context.
