Background: Smartphones offer a variety of mobile applications for diverse purposes and access to services that contribute to an increased time of interaction with the device, influencing the users' health and behavior. Introduction: The time of interaction with smartphones is more intense with the younger generation, and physical, psychological, and social complications are reported. This research aims at identifying the factors associated with musculoskeletal symptoms due to the use of smartphones in university students in Brazil. Materials and Methods: The study has a quantitative transversal type approach, with 522 college students between the ages 18 and 26. A structured questionnaire was applied in 2017, to characterize the sociodemographic profile, composed of information regarding the use of smartphones added to the Nordic questionnaire of musculoskeletal symptoms. Results: One of the main results found was a tendency for participants to have symptoms of musculoskeletal pain with regards to their typing methods on smartphones. When asked about the cases when such symptoms were considered to be related to the use of the device, most cited the cervical region (43.87% of cases). It was also found that those who type on their phones with the head at 45: ° and 60 ° angles are about twice as likely to have higher scores of severe symptoms than those typing with their neck at 0 ° (anatomical position). Conclusion: Within the university student population the typing position on a: smartphone and time of use are associated with the presence of pain in the cervical region.

The main objective of this study was to investigate the effects of the order of physical exercises on body composition, physical fitness, and cardiometabolic risk in adolescents participating in an interdisciplinary program focusing on the treatment of obesity. The final 12-week analyses involved 33 female adolescents who were split into two groups of concurrent training (CT): resistance plus aerobic training and aerobic plus resistance training, with equalization performed in all physical exercises. The only difference between the two groups was the order in which the exercises were performed. The results showed reductions in fat mass, body fat, and waist circumference, as well as increases in musculoskeletal mass and resting metabolic rate (p < 0.05) following the multiprofessional intervention period. However, no significant differences were observed in regard to body mass, body mass index, neck circumference, or arm circumference (p > 0.05). Maximal isometric strength and maximal oxygen consumption showed significant increases after the intervention period (p < 0.05). There were reductions in insulin, HOMA-IR, total cholesterol, triglycerides, and low-density lipoproteins (p < 0.05), and an interaction within the resistance plus aerobic training group showed lower values for triglycerides when compared to itself (p = 0.002). No difference was found in fasting glycemia for either group (p > 0.05). It is worth noting that the equalization training variables presented no differences between the two groups (p > 0.05). Based on these results, both CT methods were found to be effective in promoting health parameters in overweight and obese female adolescents, and triglyceride values decreased more in the resistance plus aerobic group. Future studies with larger samples and feeding control should be conducted to confirm or refute our findings.

Objective: to verify the effects of Senior Dance on cognitive and motor parameters and quality of life of elderly people. Methods: pre-experimental study with pre- and post-test for a group with a convenience sample composed of 20 elderly of both genders. Participants were evaluated through the agility test, the balance scale and inventories of depression and anxiety, and a questionnaire on quality of life. Elderly people participated in a physical activity program featured as Senior Dance for a period of three months. Results: the intervention resulted in improved scores in most of the variables, with significant results only for anxiety classified as temporary emotional state. Conclusion: Senior Dance was effective as physical exercise to improve the quality of life, as well as the physical and mental health of the elderly.

Purpose: The study aims to investigate whether participation to massive open online courses (MOOCs) may lead to labor market returns and through which mechanisms such relative advantage may take place. Indeed, despite high figures of registered users, empirical studies on occupational returns are limited and MOOCs may represent a viable, cost-efficient example of lifelong learning practice to respond to the demand of a better skilled workforce for the fourth industrial revolution. Design/methodology/approach: The study is based on qualitative empirical material constituted by a set of 21 qualitative semi-structured interviews conducted in 2019 among learners who registered in MOOCs provided by European higher education institutions. Findings: Interviews return a situation in which MOOCs are beneficial for work: learners appreciate the new knowledge and skills they can access, with time flexibility and low entry cost. However, MOOCs positive contribution is not at everyone’s reach: self-selection issues tend to further advantage individuals with high levels of education and individual resources. Moreover, MOOCs can increase the risk of a shift of responsibility for training to the employees and qualify as a lower tier type of qualification, reinforcing social closure mechanisms based on educational credentials. Originality/value: The study contributes to the empirical analysis of MOOCs economic returns empirically, by providing original qualitative material. Second, it contributes theoretically by bridging literature on economic and occupational returns to education on one side and literature on digital technologies in education on the other, providing new insights on the potentials and limits of MOOCs as a new form of lifelong learning.

RESUMO As doenças respiratórias afetam milhões de pessoas, principalmente os idosos, e as mudanças climáticas estão entre os fatores predisponentes, interferindo na saúde dessa população. O objetivo deste estudo foi avaliar o pico de fluxo expiratório de idosos institucionalizados e não institucionalizados durante as quatro estações do ano. Estudo de coorte prospectivo com 67 idosos de ambos os sexos, residentes na cidade de Maringá (PR) e divididos em dois grupos: idosos institucionalizados (n=37) e idosos não institucionalizados (n=30). Os dados foram coletados durante um mês, uma vez por semana nas quatro estações do ano, totalizando 16 avaliações. O pico de fluxo expiratório foi avaliado com o equipamento peak flow meter. A comparação dos dois grupos de idosos foi feita por análise de variância de dois fatores utilizando o post-hoc de Bonferroni. A menor média de pico de fluxo expiratório para os idosos institucionalizados e não institucionalizados foi no verão (176,2±60,2 e 263,2±116,2), seguido pelo outono (193,4±59,5 e 287,5±118), inverno (215,3±82,5 e 291,5±08,4) e primavera (221,7±83,5 e 291,5±08,4). Conclui-se que o pico de fluxo expiratório de idosos varia de acordo com as estações do ano, porém os institucionalizados apresentam valores mais baixos. Os mais altos são encontrados na primavera, embora aquém do valor predito para os idosos de ambos os grupos.
