Young athletes are influenced by different physical, psychological, and social factors. Social factors significantly impact a young athlete’s growth. Parents, coaches, and schools are important factors in young athletes’ sports careers. Achieving sport success without their support would be a real challenge. Social capital is a resource that comes from social relationships and social networks. It is a resource that impacts athletes and sports performance. The aim of this study was to determine the connection between social capital and competitive success in young tennis players. This research was conducted with participants of an ITF (International Tennis Federation) junior tournament in tennis. Research included 75 tournament players (N = 36 girls, age: 15.54 ± 1.29 years; N = 39 boys, age: 16.13 ± 0.98 years). Participants filled out a questionnaire which evaluated their social capital. Social capital predictors were significant predictors of sporting success (13.1% variance explained), which indicated that there is a moderate association between social capital indicators and sport success in young tennis players. Sports performance was higher with a higher degree of family and sports team social capital among girls. It was higher with a lower school social capital among boys. Intervention that leverages social capital might serve as an avenue for performance promotion in youth.

Conclusión. El somatotipo de tenimesistas chilenos tiene una orientación hacia mesoendomorfía y un predominio XX y alelo X del gen ACTN3 y, predominio del genotipo DI y alelo D del gen ECA, estas características podrían ofrecer una ventaja genética en cuanto a niveles de fuerza y potencia muscular, posiblemente facilitando la práctica y el éxito competitivo en estos tenimesistas chilenos.  Abstract. Introduction. The study of anthropometric and genetic variables are essential as determinants of sports performance. Objective. The objective of the study was to determine the somatotype and the frequency of genotype and allele of 𝜶-actinin 3 (ACTN3) R577X and angiotensin converting enzyme (RCT) I / D polymorphism of Chilean table tennis players. Method. 24 male table tennis players (age 22.1 x 5.4) of Chile's national rankings were studied. Obtaining ACTN3 and ACE was collected by sample of saliva and analyzed by polymerase chain in real time. The body structure was characterized through the somatotype method proposed by Carter. From descriptive statistics, the mean values of somatotype, frequency of classification and location of somato letter were analyzed, in addition, of genotype frequency values and allele of ACTN3 R/X and ECA I/D polymorphism according to number of occurrence and percentage. Results. It demonstrated a predominance of mesoendomorphy and endomorphy classification, a higher phenotypic frequency XX with predominance of allele X for the ACTN3 gene and higher frequency of DI allele with predomina D for ACE. Conclusion. The somatotype of Chilean tenimestists has an orientation towards mesoendomorphy and a predominance of the genotype XX and allele X of the ACTN3 gene and, predominance of the DI genotype and allele D of the ACE gene, these characteristics could offer a genetic advantage in terms of strength levels and muscle potency, possibly facilitating practice and competitive success in these Chilean tenimists.

Background: The benefits and risks of performing popular wrist-loading sports at a young age have not been investigated systematically. We aimed to evaluate positive and negative long-term wrist-related health effects of sports performance requiring repetitive wrist loading during youth. Methods: Six databases were searched for cohort and cross-sectional studies. Three investigators selected studies evaluating quantitatively measured health effects of upper extremities in athletes practicing wrist-loading sports (gymnastics, tennis, volleyball, field hockey, rowing, and judo) for minimally 4 months before the age of 18. Results: A total of 23 studies with 5 outcome measures, nearly all of moderate to good quality, were eligible for inclusion. Bone mineral density and bone mineral content were higher in athletes compared with controls and in tennis players’ dominant arm. Mixed results were found for ulnar variance in gymnasts. Handgrip strength was greater in tennis players’ dominant arm and in experienced gymnasts. Conclusions: Wrist-loading sports performance during youth can promote bone strength in wrists and dominant handgrip strength, but evidence on the lasting of these effects and on prevalence of wrist joint degeneration in former young athletes is limited. For better counseling of young athletes and their parents, future studies with increased comparability are essential, for which recommendations are provided.

Sports technology enhances athletes’ performance by providing feedback. However, interaction techniques of current devices may overwhelm athletes with excessive information or distract them from their performance. Despite previous research, design knowledge on how to interact with these devices to prevent such occasions are scarce. To address this gap, we introduce subtle displays as real-time sports performance feedback output devices that unobtrusively present low-resolution information. In this paper, we conceptualize and apply subtle displays to tennis by designing Tactowel, a texture changing sports towel. We evaluate Tactowel through a remote user study with 8 professional tennis players, in which they experience, compare and discuss Tactowel. Our results suggest subtle displays could prevent overwhelming and distracting athletes through three distinct design strategies: (1) Restricting the use excluding duration of performance, (2) using the available routines and interactions, and (3) giving an overall abstraction through tangible interaction. We discuss these results to present design implications and future considerations for designing subtle displays.

Anterior Pelvic Tilt

The aim of this study was to compare the thoracic and lumbar curvatures and pelvic tilt in relaxed standing and maximal trunk flexion among highly-trained young athletes from three different sports disciplines. Thirty-two male canoeists, 30 male kayakers and 24 male tennis players were recruited for the study. The Spinal Mouse® system was used to measure the thoracic and lumbar sagittal spinal curvatures and pelvic tilt in relaxed standing and maximal trunk flexion in sitting with flexed (McRae & Wright test) and extended knees (sit-and-reach test). Significant differences were found in maximal trunk flexion tests among athletes. Kayakers and canoeists showed increased anterior pelvic tilt compared to tennis players in the McRae & Wright (p<.01) and decreased posterior pelvic tilt in the sit-and-reach (p<.001) tests; however, canoeists had increased posterior pelvic tilt compared to kayakers in the sit-and-reach test (p<.01). Canoeists had increased thoracic kyphosis curvature compared to kayakers (p<.01) and tennis players (p<.001) in the sit-and-reach test. Spinal sagittal curvatures and pelvic tilt in relaxed standing did not show significant differences. In conclusion, specific sport training may be associated with adaptations in the sagittal spinal curvatures and pelvic tilt when maximal trunk flexion positions are performed.

School Social Capital

In intense academic environments such as in South Korea, students experience extreme levels of academic stress. This stress peaks as students prepare for the college entrance exam in the final year of high school. Stress is associated with a host of negative outcomes, and academic stress is the leading cause of suicidal ideation among youth in South Korea. Research suggests that in high-stress contexts such as this, social capital can improve academic success and mental health, while reducing risky or deviant behaviors. However, this research has predominantly focused on Western contexts. Because of the unique intensity of educational pursuits and intense investment in education by parents, South Korea provides a compelling case for research on the effects of family and school social capital on youth academic stress. Using data from the Korea Youth Panel Survey (N = 2753), we find that particular components of family and school social capital can both reduce and exacerbate academic stress. While measures of closeness and connection to parents reduced academic stress, school social capital had a limited impact on academic stress. Furthermore, there may be a limit to the effectiveness of social capital to help with academic stress before it becomes too much of a good thing.

Background Despite their importance in population health among children and adolescents, our understanding of how individual items mutually interact within and between pediatric health-related quality of life (HRQOL) and school social capital is limited. Methods We employed network analysis in a general population sample of 7759 children aged 9–15 years to explore the network structure of relations among pediatric HRQOL and school social capital items measured using validated scales. Furthermore, network centrality was examined to identify central items that had stronger and more direct connections with other items in the network than others. Network structure and overall strength of connectivity among items were compared between groups (by sex and age). Results Our analysis revealed that the item related to school/academic functioning and the item related to shared enjoyment among students had the highest strength centrality in the network of HRQOL and school social capital, respectively, underpinning their critical roles in pediatric HRQOL and school social capital. Additionally, the edge connecting “I trust my friends at school” and “trouble getting along with peers” had the strongest negative edge weight among ones connecting school social capital and pediatric HRQOL constructs. Network comparison test revealed stronger overall network connectivity in middle schoolers compared to elementary schoolers but no differences between male and female students. Conclusion The network approach elucidated the complex relationship of mutually influencing items within and between pediatric HRQOL and school social capital. Addressing central items may promote children’s perceived health and school social capital.
