Participation in organized sports is associated with decreased likelihood of unhealthy lifestyle habits in adolescents.

Adolescence is a pivotal time for investing in both present and future health. Thus, it is important to identify arenas for promoting positive adolescent health behaviors and preventing negative ones. The aim of this study was to investigate the associations between organized sports participation (OSP) and a broad range of lifestyle habits in Norwegian adolescents. A comprehensive survey was completed by 13 269 junior high and high school students in southern Norway. Multivariable binary logistic regression models, adjusted for gender, age, and parental education, were used to investigate the associations between OSP and adolescent substance use, dietary habits, physical activity level, passive vs active transportation, screen time, and sleep duration. Inverse associations were found between OSP and adolescent substance use (odds ratio 0.40 [95% confidence interval 0.30-0.52] to 0.68 [0.61-0.76]), irregular consumption of main meals (0.58 [0.53-0.63] to 0.78 [0.70-0.89]), high intake of unhealthy food and beverages (0.55 [0.47-0.65] to 0.86 [0.75-0.98]), low intake of healthy food items (0.57 [0.51-0.63] to 0.77 [0.70-0.84]), low physical activity level (0.15 [0.14-0.17]), high screen-based activity (0.61 [0.55-0.67]), passive vs active transportation (summer; 0.79 [0.72-0.86] and winter; 0.84 [0.77-0.92]), and short sleep duration, during both weekdays (0.57 [0.52-0.63]) and weekends (0.79 [0.69-0.89]). In conclusion, adolescents participating in organized sports had decreased odds for engaging in several unhealthy lifestyle habits compared with non-participants, indicating that organized sports may be a relevant setting for promoting healthy behaviors among adolescents. Future studies are, however, needed to confirm a possible causal relationship.

Childhood football play and practice in relation to self-regulation and national team selection; a study of Norwegian elite youth players.

Childhood sport participation is argued to be important to understand differences in self-regulation and performance level in adolescence. This study sought to investigate if football-specific activities in childhood (6-12 years of age) is related to self-regulatory skills and national under 14- and 15-team selection in Norwegian elite youth football. Data of practice histories and self-regulatory skills of 515 youth football players selected at Norwegian regional level were collected and further analysed using multilevel analyses. The results revealed that high self-regulated players were more likely to be selected for national initiatives, and increased their involvement in peer-led football practice and adult-led football practice during childhood, compared to players with lower levels of self-regulation. While national level players reported higher levels of peer-led football play in childhood, the interaction effect suggest that the regional level players increased their involvement in peer-led play during childhood compared to national level players. In conclusion, the findings indicate that childhood sport participation may contribute to later differences in self-regulation, and highlights the importance of childhood engagement in football-specific play and practice in the development of Norwegian youth football players.

The role of gender in the relationship between physical activity, appearance evaluation and psychological distress.

BACKGROUND: Based on previous research, the aim of this cross-sectional study was to examine the indirect effect of physical activity on psychological distress through appearance evaluation. The indirect effect was hypothesized to be conditional on gender, with the effect being more profound among females than among males. METHOD: A total of 2055 adolescents (Mage  = 15.3) completed a self-report questionnaire. RESULTS: Physical activity was indirectly related to psychological distress through appearance evaluation in both males and females, but the indirect effect was stronger for females than for males. CONCLUSIONS: Physical activity may prevent distress through enhanced appearance evaluation.

Towards More Sustainable Sports: Analyzing the Travel Behavior of Adolescent Soccer Players in Southern Norway.

Mitigating climate change is a global challenge demanding effort from all sectors, and sports are no exception. While transportation is one of the key issues regarding sustainable sports, the methods by which children and adolescents get to practice have not received much attention. The objectives of this study were, therefore, to present how adolescents in Southern Norway travel to soccer practice and assess how the mode of transportation is related to sex, socioeconomic status, age, ethnicity, and distance from home to practice. Cross-sectional data were collected from 558 adolescent soccer players (398 boys and 190 girls) representing 30 different clubs from settlements of varying rurality. While most of the participants lived within cycling distance from the field of practice, the majority opted for passive modes of transportation (55% passive vs. 45% active). A logistic regression analysis found that traveling distance and age were associated with active transportation habits, while sex, ethnicity, and socioeconomic status were not. Further research is needed to examine the main barriers to active travel for this already active population, as active transport represents an opportunity for sports to become more sustainable.

Experiences of Older Adults Preparing for Their First Triathlon: "A Qualitative Study of the Participation in an Endurance Training Intervention."

Purpose: The overall aim of the present study was to explore the experiences of older adult exercisers participating in an individualized training program lasting 3 months preparing for completing a triathlon competition. Methods: Fourteen older Norwegian adults (median age (interquartile range, IQR) for males (N=10) and females (N=4) were 70.0 (65.0-75.5) and 57.5 (56.3-62.5) years, respectively) participated in 3-month individualized training program comprising three weekly sessions of running, cycling, and swimming. Both field- and laboratory-based testing were conducted. The participants attended two sports nutrition and competitive psychology seminars focusing on triathlon competition. The participants were interviewed in depth in three different focus groups. Thematic analysis was utilized to analyze the findings. Results: Participants improved their performance in all field-based tests. After completion of the thematic data analysis the main finding and overarching theme of well-being and being fit emerged. Additionally, three main themes were identified: 1) motivation; 2) progress and coping; and 3) breaking barriers. Conclusion: Psychological well-being and satisfaction of being fit seem to be vital to participate in a triathlon competition. Promoting specific age-appropriate participation in sports activities can be an effective strategy for promoting a healthy lifestyle among the elderly.

Referee Bias in Professional Football: Favoritism Toward Successful Teams in Potential Penalty Situations.

Past studies have indicated that multiple factors may influence sport referees' decisions, such as pressure from spectators and athletes' reputation. Grounded in the social impact theory framework, this study examined whether Norwegian Premier League (NPL) referees are biased by a team's success when awarding penalties. Using video footage (similar to video assistant referees), an expert panel (EP) of four NPL referees evaluated all potential penalty situations (N = 43) involving either of two successful teams during an entire NPL season. Fifty-five potential penalty situations from matches without successful teams were also rated. Overall, the match referees identified 73.3% (22 of 30) of the EP-identified penalties during matches without successful teams. Successful teams were awarded 110% (11 of 10) of the EP-identified penalties, while their opponents were awarded 12.5% (1 of 8). Chi square statistic revealed that successful teams were more likely to receive an incorrect penalty compared with their opponents, and less likely to be denied a penalty they should have been awarded. These findings indicate that referees' decisions may be unintentionally biased by a team's success, extending our knowledge about how football referees may be influenced by social forces.

A Preliminary Analysis of the Importance of Distance, Angle, and Insight When Soccer Referees Make Penalty Decisions.

Soccer referees move freely on the pitch to place themselves in the best location for making decisions. While Football Association UK (FA) highlights that a referee should never be more than 20 m away from the playing situation, previous studies have been inconsistent in indicating appropriate distance to a situation for increasing the likelihood of a correct decision. Further, appropriate angle and insight are also likely to influence the correctness of referees' decisions. The aim of this study was to provide an initial investigation of elite referees' positioning in the field (distance, angle, and insight) when making correct and erroneous decisions in potential penalty situations. An expert panel (EP) consisting of two active referees with relevant academic background analyzed referees positioning when making correct or erroneous decisions regarding penalties. The EP were asked to qualitatively analyze referees positioning in selected video clips by using recommended technical refereeing criteria and practical guidelines (i.e., the referee's distance from, angle to, and insight into the penalty situations). Of the 42 situations evaluated, the results revealed that the EP termed the referees positioning as good in terms of angle and insight in 25 and 21 situations, respectively. The angle was average in seven situations and poor in 10 situations, and the insight were average in 10 situations and poor in 11 situations. The match referee was <10 meters away in 12 situations, 10-20 m away in 22 situations, and >20 meters away in eight situations. Results revealed that referees' positioning that resulted in the highest rate of correct decisions were when the distance were under 10 meters (83% correct decisions), good angle (88%), and good insight (86%). In contrast, referees were poorly positioned in terms of angle and/or insight in nine of the 15 erroneous decisions made. Although the present study was a preliminary qualitative investigation containing a limited number of potential penalty situations, the findings indicated that soccer referees are more likely to produce a correct decision in potential penalty situations when the distance to the situation is under 10 meters, when the insight to the situation is good and the angle to the incident is good. In contrast, the match referees generally had a poor starting position to assess the penalty situations where they landed on a wrong decision. While previous studies have been somewhat inconsistent in indicating optimal referee positioning in soccer, the present study highlights the potential value of a more qualitative approach to understand referees' positioning and subsequent decision-making accuracy.

Difference in physical fitness in children with initially high and low gross motor competence: A ten-year follow-up study.

The aim of the study was to investigate the difference in relative physical fitness between children with initially high and low gross motor competence in a ten-year prospective study. A sample of 49 children from a local primary school was tested on gross motor competence and physical fitness in 1st grade (5/6 years old). The children were tested again in 2nd (motor competence only), 7th, and 10th grade (15/16 years old). The sample was divided into two groups; initially high and low gross motor competence, according to score (median-split) on the Körperkoordinationstest für Kinder-test battery in 1st grade. Results suggested that the initially high gross motor competence-group performed significantly better on a multidimensional physical fitness test, compared to the initially low gross motor competence-group at all time-points. There were also statistically significant differences between the groups in gross motor competence in 7th and 10th grade, with the initially high gross motor competence-group scoring most favorable. The findings from the present study highlight the importance of identifying and supporting young individuals with low gross motor competence, to prevent low levels of physical fitness in the future.
