Between late adolescence and early adulthood, people experience a precipitous decline in their participation in physical activity. Those attending college or university are often presented with opportunities to partake in physical activity, sometimes under compulsory conditions and sometimes under elective conditions. This study examined the psychological and behavioural characteristics of freshman students under these two separate conditions. The main finding was that students under the elective condition felt more competent and motivated compared to those in the compulsory condition. They were also more physically active. When offered as electives, tertiary level physical activity education courses may be limited in reach, primarily attracting those who would likely be physically active without any such coursework.

Despite significant advances in the knowledge and understanding of associations between the phenomenon of excess body weight (hereafter “overweightness”) and fundamental movement skill (FMS) proficiency, the question of how overweightness affects critical features of movement remains unanswered. This study examined the differences in the proficiency of FMS between boys and girls with different weight status on the level of critical features. Three hundred and twenty-two boys and girls aged 5 to 10 years were assessed in eight FMS (run, vertical jump, long jump, ball catch, ball kick, ball pass, ball bounce, and forehand strike) and were assigned to non-overweight and overweight groups according to their waist-to-height ratio, with a cut-off point of 0.5. FMS score differences (p < 0.05) between boys and girls that can be frequently observed in the non-overweight group of children were not determined in the overweight group of children (p ≥ 0.131). Overweight boys performed worse in a higher number of skills’ critical features than overweight girls did when compared to non-overweight groups. With weight gain, boys might experience a more significant decline in FMS proficiency than girls do because of the higher scores when non-overweight. The critical features of FMS indicate that overweightness might affect postural control and coordination, which this paper discusses.

Muscle denervation is one of the most critical pathological factors involved in muscle atrophy as a result of ageing. This study aims to investigate the chronic effect of high-intensity interval training (HIIT) on cross-sectional areas and muscle denervation genes, interpreted in the plantaris muscle atrophy of aged rats. Twenty-eight aged and young rats were divided into four different groups, including exercise and control. The training protocol included six weeks of HIIT. Animals were sacrificed 48 hours after the last training session, and the plantaris muscle was removed. To measure Gadd45a mRNA and NCAM1mRNA, we used a real-time PCR technique. The cross-sectional area was measured with photomyography using an H&E technique. The results showed that ageing significantly decreased NCAM1 mRNA in the aged control group (p=0.0001) and exercise leads to a significant increase (interaction effect) of it (p=0.003). Gadd45a mRNA was significantly increased due to ageing (p=0.009), and exercise resulted in a significant decrease in that in the aged exercise group (p=0.04). The cross-sectional area in the aged control group was significantly smaller than in the young control group (p=0.046). In contrast to young groups, exercise could increase the cross-sectional area in the aged exercise group compared with the aged control group, but it was not significant (p=0.069). It seems that HIIT could improve ageing-induced muscular atrophy, although denervation-involved gene modification leads to an increase in the muscular cross-sectional area; therefore, it improves muscular atrophy due to ageing.

The primary goal of the present paper is to analyse and compare the criteria on the conditions and requirements for academic promotion in three countries: Serbia, Slovenia and Montenegro. The University of Novi Sad, the University of Ljubljana, and the University of Montenegro were selected to be subjects in this study. The sources used for the analyses in this study were the official criteria on the condition and requirements for academic promotion at the abovementioned universities. The authors used a descriptive method with the consulting of competent sources and personal experiences. First, it is interesting to note that the universities in Serbia and Slovenia follow official documents at two levels: one at the national level issued by the relevant higher education council/agency and the second at the university level issued by the senate of each university, whose criteria are more strict in terms of quantitative requirements. However, this is not the case in Montenegro, where universities follow only the national criteria in the research quality evaluation. In each country, evaluation exercises usually recognize three fields, one of which is social sciences and humanities, which is concerned with an entire range of interdisciplinary and multidisciplinary scientific areas. Comparing the minimum standards for the appointment of university teachers, it is essential to highlight that Slovenian regulations are the most demanding, especially with regards to quantitative criteria, while Serbian and Montenegrin criteria are similar to each other; however, it is necessary to highlight that Montenegrin regulations contain some unusual criteria, such as the requirement that scientific research work must be achieved through one single-author paper published in an international journal for promotion to academic titles at all three levels (assistant, associate and full professor) in social sciences and humanities; however, this is not the case in other academic fields.

Digital media engagement in families in Singaporean society is increasing at an unprecedented pace. Limited research in the last five years in Singapore shows that young children experience significant amounts of screen time from television, computers and other forms of mobile digital devices, even before primary school. For children, digital media use can aid with learning, but its overuse has inimical effects on learning and health. As digital media use in children increases faster than research on its impact, it is essential to develop a tool that can monitor changes in digital media habits of children over time. This study aimed to develop an online questionnaire for parents to report on the digital media habits of children. An online questionnaire bundle, Surveillance of digital-Media hAbits in earLy chiLdhood Questionnaire (SMALLQ™), organized into sections ((I) Digital-media use of parent and child, (II) Non-digital media behaviour of the child, (III) Parent and child information) was developed for the purpose of charting digital media use and changes over three years (2018, 2019, and 2020). The results showed that SMALLQ™ has face and content validity and was practicable for Singapore. Furthermore, based upon a similar methodology for developing the SMALLQ™, the development of Child-SMALQ (Surveillance of digital MediA use in chiLdhood questionnaire) and Adolescent-SMALQ (Surveillance of digital MediA use in adoLescence questionnaire) are directions for future research.
