UNASSIGNED: The high incidence of knee injuries in football/handball challenges effective prevention. Identifying tangible and modifiable factors associated with a knee injury may innovate preventive actions. Engaging key stakeholders can reveal crucial insights that could improve knee injury prevention in football/handball.
UNASSIGNED: To investigate football/handball stakeholders\' perspectives on reasons for acute and severe knee injuries to generate a conceptual model on important factors associated with knee injuries in football/handball.
UNASSIGNED: Mixed-method participatory Group Concept Mapping was applied to collect statements from football/handball stakeholders (players/coaches/healthcare staff/researchers) on the question, \'What may explain why some players sustain a knee injury?\'. Participants rated the importance and feasibility of screening for each statement. Multidimensional scaling and hierarchical cluster analysis produced a cluster map, forming the basis for developing a final conceptual model.
UNASSIGNED: Stakeholders (n=37) generated and sorted 100 statements. Cluster analysis followed by cluster map validation yielded seven themes: (1) the player\'s physical and motor skill profile, (2) preparation and training, (3) footwear and playing surface, (4) the sport\'s impact on the risk of injury, (5) mental and physical fatigue, (6) history of injury and 7) genetics and context. A final conceptual model illustrating factors associated with knee injuries in football/handball was developed. Forty-six statements were identified as both important and feasible to screen for.
UNASSIGNED: Stakeholders\' perspectives on knee injuries in football/handball revealed a complex interplay of factors. We developed a conceptual model fostering stakeholder dialogue for enhanced prevention. Key among its themes is \'preparation and training\'.

OBJECTIVE: To investigate adolescents\' experiences with the food selection at the sport arena.
METHODS: Four focus group interviews were conducted with 4-6 participants each. Interviews were recorded and transcribed verbatim. The transcripts were coded in NVivo and the analysis was guided by thematic analysis.
METHODS: Adolescents from handball and football clubs in Oslo and Viken, Norway, participated in the study.
METHODS: A total of nine boys (11-14 years old) and ten girls (11-14 years old) participated in the study.
RESULTS: We identified four main themes: interest for healthy food; experiences with the food selection at the sports arena; factors influencing participants\' food choices at the sports arena and expectations related to a healthy food selection at the sports arena. Adolescents across the focus groups experienced the food selection at the sports arena as unhealthy. Price, marketing and availability of unhealthy food were important factors that influenced their food choices at the sports arena. The trainer appeared to motivate the participants to eat healthy.
CONCLUSIONS: Participants wished for a healthier food selection at the sports arena. Cost of food emerged as a factor that influenced their food choices. Our study also indicates that marketing of unhealthy food and beverages should be restricted, to influence adolescence food choice towards healthier alternatives.

In the last few decades, there has been a movement from individualistic and mechanistic notions of learning to approaches that turn attention to the significance of the context of learning. While these approaches have been utilized to point out the significance of the environment for skill acquisition, they have primarily been oriented towards performance-oriented milieus. Inspired by the theory of situated learning in \"communities of practice\" (CoP), the aim of the study is to analyze learning processes among members (participants, coaches, parents, etc.) of a diverse sporting community. The article is based on a multiple-case study of a Danish handball community named Lykkeliga (Happy League) that within a few years has attracted more than a thousand children with a remarkable diverse range of age, gender, diagnosis, and disabilities. The data collection included participant observation of training and tournament situations in two clubs over a 3-month period, along with informal interviews. The thematic analysis reveals a range of legitimate ways of participating for members of Happy League clubs, including sitting on the bench and even dating during practice. In sum, our case study sheds light on how situated learning in sporting communities may be directed towards inclusion and expansive understanding of what it means to be a sport participant.

BACKGROUND: Proper proprioceptive and neuromuscular control is crucial for the overhead athlete\'s performance. The aim of the present study was to evaluate the shoulder joint position sense (JPS) levels in overhead throwing athletes. The secondary aim was to confront the proprioceptive abilities with glenohumeral adaptive changes and pathologies among athletes.
METHODS: Ninety professional handball players and 32 healthy volunteers were recruited. JPS levels were measured by an electronic goniometer and expressed as values of an active reproduction of the joint position (ARJP) and as error of ARJP (EARJP) in 3 different reference positions for each movement (abduction and flexion at 60°, 90°, and 120°; internal [IR] and external rotation [ER] at 30°, 45°, and 60°).
RESULTS: Side-to-side differences revealed significantly better values of EARJP for the throwing shoulders in abduction at 90° and 120°, flexion at 90° and 120°, IR at 60°, and ER at 30° and 60° compared with the nonthrowing shoulders. Handball players showed significantly better proprioceptive levels in their throwing shoulder compared to the dominant shoulder of the control group in abduction at 90° (P = .037) and 120° (P = .001), flexion at 120° (P = .035), IR at 60° (P = .045), and in ER at 60° (P = .012).
CONCLUSIONS: Handball players present superior shoulder JPS in their dominant throwing shoulder at high range of motion angles when compared to a nonathlete population and to their own nondominant shoulder.

Energy deficits are often observed in athletes, especially in female athletes, due to the high expenditure of sport and strict diets. Low energy availability can cause serious health problems and affect sport performance. The aim of this study was to evaluate the effects of different personalized dietary plans on physiological and physical factors related to energy deficit syndrome in female professional handball players. Twenty-one professional female handball players, aged 22 ± 4 years, 172.0 ± 5.4 cm and 68.4 ± 6.7 kg, divided into three groups (FD: free diet; MD: Mediterranean diet; and AD: high antioxidant diet), participated in this 12-week randomized controlled trial. Energy expenditure through indirect calorimetry, energy availability, 7 day dietary intake analysis, blood pressure, cholesterol, menstrual function, body composition by both anthropometry and bioelectrical impedance, and strength performance were assessed. All participants showed low energy availability (<30 kcal/lean mass per day); despite this, all had eumenorrhea. Significant improvements were found after the intervention in all components of body composition (p < 0.05). In the remaining variables, despite slight improvements, none were significant neither over time nor between the different groups. Low energy availability has been observed in all professional female handball players, which may lead to serious consequences. A longer period of intervention is required to assess the differences between diets and improvements in other parameters.

Low energy availability may precede or be caused by cognitive disturbances in professional athletes. Related psychological problems include disordered eating patterns, body shape preoccupation, depression or anxiety. The objective of this research was to evaluate the effects of different personalised dietary plans on psychological factors in young professional female handball players with low energy availability. This 12-week randomised clinical trial involved 21 female players aged 22 ± 4 years, 172.0 ± 5.4 cm and 68.4 ± 6.7 kg divided into three groups (FD: free diet; MD: Mediterranean diet; HAD: high antioxidant diet). Eating behaviour (Eating Attitude Test, EAT-26: diet, bulimia and oral control subscales), body image (Body Shape Questionnaire, BSQ) and mood state (Profile of Mode State, POMS: tension, vigour, anger, depression, fatigue) were assessed. All participants showed low energy availability (<30 kcal/lean mass per day). The different plans showed no significant differences between them but significant differences over time within groups for the variables: body image, Tension, Vigour and Depression (p < 0.05). Eating behaviour improved slightly but did not show statistically significant changes. Following an adequate nutritional planning for athletes seems to improve the mood and body perception of young female handball players. A longer intervention period is required to assess the differences between diets and improvement of other parameters.

The return to sport after knee injury is challenging. This is burdensome for sports with a high incidence of injuries, such as team handball. Various tests guide decision making, but often the athlete\'s preinjury performance of these measures remains unknown. Moreover, objective return-to-sport criteria of a matching population are missing. The purpose of this study was to evaluate objective measures of knee capability in handball depending on players\' age. Two hundred sixty-one handball players performed a functional test battery designed to evaluate knee capability after an anterior cruciate ligament injury: two- and one-legged stability analysis, jumps, speed tests, and agility assessments. For age-specific evaluation, athletes were divided into three age groups (16-19; 20-29;≥30 years). Male players showed differences in two and one-legged jumping height (p<0.02) as well as power per body weight (p<0.01) between age groups. Young female players reached better results in two-and one-legged stability. Besides the quick feet test, results of females did not differ between age groups. Functional knee stability in healthy handball players is partly influenced by age, and females show better results in stability and male athletes in power measurements. This aspect should be considered for return to sports testing and underlines the importance of performance measures in athletic testing.

The main objective of this study was to test the relationship between shoulder internal rotation strength and standing throwing velocity. A repeated measures cross-sectional study was conducted with 20 professional handball players (mean ± SD; age: 19.28 ± 2.55 years, weight: 81.52 ± 9.66 kg, height: 185 ± 6 cm, BMI: 23.74 ± 1.69). The participants were instructed to perform eight standing throws from the 7 m line of the handball court at maximum velocity to calculate the mean and maximum throwing velocity. An incremental test was performed to calculate the repetition maximum (1-RM) of internal rotation shoulder strength. A Pearson\'s correlation analysis with a 95% confidence interval (95% CI) was performed to determine whether correlations existed between dominant arm internal rotation strength characteristics and maximum and mean ball-throwing velocity. There is no correlation between the internal rotation strength of the throwing shoulder and the velocity of the ball in the standing handball throw.

UNASSIGNED: Handball is associated with a high risk of overuse shoulder injury. This study investigated if an injury prevention programme effectively reduces overuse injury to the throwing shoulder of handball athletes.
UNASSIGNED: 61 men\'s and women\'s handball teams (u-19 and senior athletes) were cluster-randomised into an intervention and a control group in the 2019-2020 season. Players of the intervention group regularly carried out an injury prevention programme. Both groups documented overuse shoulder injuries via an online questionnaire every second week. The primary endpoint was the prevalence of overuse injury to the throwing shoulder. Secondary endpoints were the influence of compliance on the primary endpoint and intensity of overuse shoulder symptoms measured by a shortened, handball-specific Western Ontario Shoulder Index (WOSI).
UNASSIGNED: 31 teams (295 players) in the intervention group and 30 teams (284 players) in the control group were included for analyses. The overall questionnaire response rate was 61%. The average prevalence of overuse shoulder injury did not significantly differ between the intervention group (n=109, 38.4% (95% CI 32.9% to 44.2%)) and the control group (n=106, 35.9% (95% CI 30.7% to 41.6%), p=0.542). Compliance with the intervention programme did not significantly affect overuse shoulder injury (p=0.893). Using generalised estimating equations for WOSI, the estimated mean for the intervention group was 44.6 points (95% CI 42.0 to 47.1) and 47.6 points for the control group (95% CI 44.9 to 50.3, p=0.111).
UNASSIGNED: A multicomponent exercise programme using rubber bands and stretching did not significantly reduce the prevalence or symptoms of overuse throwing shoulder injury in handball athletes of both sexes. Randomised controlled study; level of evidence I.
UNASSIGNED: ISRCTN99023492.

Sport participation is considered a positive pastime endower that can offer a range of positive outcomes for children and youths. It has also increasingly been recognized as a potentially important context for fostering social inclusion for minority youths. Yet across Europe, minority girls are participating in sport to a lesser degree than their majority counterparts. Using self-determination theory (SDT) and the social ecological model as the framework, this study explored the reasons why a particular project aimed at recruiting minority girls to organized team sport succeeded in doing just that. A case study design was adopted to provide an in-depth analysis of how this project satisfied the basic psychological needs of minority girls. Nine girls, four parents, two coaches, and two project team members were interviewed about the project and sport participation in general. Data were analyzed using thematic analysis. Two main themes were identified, a sense of being facilitated and inclusion in the sport environment. The former emphasized the importance of aligning the participation with the girls\' cultural norms and values, particularly in the beginning. It also included practical issues such as finances, reminding us that participation in sport is not just a motivational issue. The latter focused on the importance of including the girls in the general sports program, regardless of their athletic abilities at the onset of their participation and creating a mastery environment. Moreover, by removing remediable differences between the minority and majority girls, such as having the right equipment, seemed important to fostering a sense of belonging in the sports club. Additionally, establishing meaningful relationships with coaches and majority counterparts seemed to be a major motivating factor.
