Head and neck ice hockey injuries in children: an analysis of the NEISS database.

OBJECTIVE: Our objective was to describe non-concussion head and neck ice hockey injuries in children in the US. METHODS: This is a retrospective cohort study using data from the NEISS database. The NEISS database was reviewed from 2010 to 2021 for injuries in the head, neck, mouth, eye, and ear related to ice hockey in children 1-18 years old. Records where the only injury was a concussion or internal head injury were removed. Frequencies were calculated and chi-squared tests were performed. RESULTS: 475 children were included, with mean age of 13.1 years old (95 % CI 12.7-13.4), and 426 (89.7 %) were male. Females were significantly younger with mean age 11.8 years versus 13.2 years for males (t = -2.4, df = 473, p = .018). 110 (23.2 %) injuries were related to hockey sticks, 92 (19.4 %) involved a fall, and 32 (6.7 %) were subsequent to body checking. 301 of the injuries (63.4 %) were lacerations, 71 (14.9 %) contusions or abrasions, and 26 (5.5 %) strains and sprains. The type of injury varied according to head and neck region (p < .001). 231 (82.8 %) of facial injuries, 16 (76.2 %) of ear injuries, and 33 (62.3 %) of oral injuries were lacerations. Eight (1.7 %) patients were admitted or observed overnight, while the rest were discharged home. CONCLUSION: Female ice hockey players sustain injuries at younger ages than males, which may reflect the loss of older girls from the sport. In older boys, injury rates may reflect the loss of mandated full face protective shields.

Exploring the dynamics of Women's field hockey performance: A comparative analysis of the impact of opponent quality between Olympic Games and Chinese National Games.

This is an observational retrospective study analyzed the performance of the Chinese women's national field hockey team during the 2020 Tokyo Olympics and 2021 National Games to assess the impact of opposition quality on performance. Game statistics were collected using notational analysis software for 76 Olympic and 40 National Games matches. Non-parametric Mann-Whitney U tests were used to compare tournaments. No significant differences existed for 35 out of 38 metrics, except Offense in 25-Yd Area (P = 0.013), Handball Style (P = 0.000) and Entry into Arc - Right Lane (P = 0.017). When exclusively considering Chinese national team's observations, superior National Games performance did emerge for Shot (P = 0.046), Goal from Short Corner (P = 0.044), Into the Arc (P = 0.046), Entry into Arc - Q3 (P = 0.009), Dribble into the Arc (P = 0.046), Handball Style into Arc (P = 0.041), Forehand Shot (P = 0.033), and Small Skill Shot (P = 0.014). The study underscores the influence of opposition quality on team performance, with a need for targeted improvements in arc penetration efficacy, conversion rates of shots to goals, and adaptation of tactical approaches against stronger defenses. The research points towards the need for strategic high-performance programs, improved domestic league quality, and a structured youth development system to elevate the overall standard of Chinese field hockey to achieve global competitiveness.

Building a healthy nation: A white paper on Olympic sports and the Indian education system.

The Indian education system has produced top-class global corporate leaders in recent decades. The combination of a solid educational foundation, work ethic, adaptability, technical and analytical skills, leadership abilities, networking, entrepreneurial spirit, and cultural values collectively contribute to the success of Indian students and professionals in the corporate world. On the contrary, India's overall performance in Olympic sports has been modest compared to its population and potential. The education system of any country has a significant role in sporting success. To fully harness the potential of sports in schools, addressing these challenges and creating a supportive environment that values and promotes sporting abilities alongside academic excellence is essential. This will require concerted efforts from various stakeholders, including the schooling system, educational institutions, government, sports organizations, corporate sponsors, and the community. This white paper aims to systematically organize the available knowledge and debates around India's sporting performance in the background of mainstream education culture. This paper also addresses the systemic devaluation, exclusion, disfranchisement, and stereotyping of sports and sportspersons in India. One key argument put forward in this paper is to extend absolute equivalence to Olympic sports disciplines (e.g., football) at par with general academic disciplines (e.g., mathematics) in terms of examinations and award of qualifications within the mainstream education system of India. And India must host the Olympics before 2047.

The relationship between off-ice testing and on-ice performance in male youth Ice hockey players.

Introduction: Ice hockey demands a unique blend of physical fitness and skill, necessitating a comprehensive understanding of the factors influencing on-ice performance. The present study was designed to examine the relationship between off-ice and on-ice performance measures in male, youth, ice hockey players. Methods: Eleven minor hockey players (Age = 9.8 ± 1.1 years) participated in two testing days: (1) off-ice and (2) on-ice assessments. Off-ice assessments included maximal aerobic power, anaerobic fitness, muscular strength (handgrip and single leg squat), muscular endurance (curl-ups and push-ups), muscular power (standing long jump and vertical jump), and 30 m sprinting speed and acceleration. On-ice testing included a 15.2 m maximum speed test, a 6.1 m acceleration test with a continuation into a 47.9 m top speed test, an agility cornering S turn test, and a shot velocity test. Results: Twenty-four out of 33 off-ice variables were significantly correlated with at least one of the 11 on-ice performance variables. From those 24, 10 were included as predictors for at least one of the on-ice performance variables. Each model was composed of either one or two predictors, where the most common predictors were 30 m Run - Split (6.1 m) Sprint time and 30 m Run - Total (30 m) Sprint Max speed (included in four out of 11 models each). The prediction formulas R2 and coefficient of variation ranged from 0.63% to 0.96% and 1.2% to 15.3%, respectively. Discussion: Diverse off-ice measures of aerobic fitness, anaerobic power, muscular strength, power, and endurance, and sprinting speed, acceleration, and agility are predictive of on-ice performance. The insights gained from this study contribute to the refinement of assessment protocols, fostering a comprehensive approach to optimizing player performance and potential. Understanding the connection between objective off-ice testing and on-ice performance can support tailored training programs and player development in male youth ice hockey.

Motivations for Using Dietary Supplements in Elite Ice Hockey-Controlling Weight and Enhancing Performance.

Background: Excessive or improper use of dietary supplements (DSs) by athletes may cause adverse effects, such as impaired performance or failing a doping test, making it important for athletes to mitigate risk and make well-informed choices when using supplements. Methods: This study used focus group interviews to examine the attitudes, motivations, and practices related to DSs among male elite ice hockey players. Results: The players used a wide range of products, ranging from vitamins to multi-ingredient pre-workout supplements. Consuming DSs was considered as a practical and convenient way to ingest sufficient calories to gain or maintain the body weight and muscle mass needed to meet the physical requirements of the sport. The athletes demonstrated a lenient and ignorant attitude when acquiring and using supplements, with a non-critical trust in the guidance provided to them by the coach or physician. Having completed basic anti-doping education in the form of an e-learning program did not appear to result in taking a more careful approach to using DSs. Conclusions: Through their DS practices, elite ice hockey players may put themselves at risk for anti-doping rule violations. A comprehensive approach is needed when aiming to prevent unintentional doping in this athlete cohort.

Safe2Play in youth ice hockey: injury profile and risk factors in a 5-year Canadian longitudinal cohort study.

INTRODUCTION: Ice hockey is a popular global sport with growing participation for boys and girls yet remains a high-risk sport for injury. While the evidence for some risk factors, such as bodychecking policy is well established, other risk factors such as player sex have been understudied. The objectives of this study were to examine factors associated with rates of game-related injury, game-related injury resulting in >7 days of time-loss, and practice-related injury in youth ice hockey. MATERIALS AND METHODS: Safe2Play was a five-year prospective cohort study (2013-2018). All injuries were identified using validated injury surveillance methodology. Multilevel Poisson regression (adjusting for cluster by team and including multiple imputation of missing covariates) was used to estimate incidence rate ratios (IRRs) for player sex, age group, bodychecking policy, year of play, level of play, weight, previous injury within last 12 months, previous lifetime concussion history, and position. RESULTS: A total of 4418 male and female ice hockey players (representing 6584 player-seasons) participating in under-13 (ages 11-12), under-15 (ages 13-14) and under-18 (ages 15-17) age groups were recruited. There were 1184 game-related and 182 practice-related injuries. Factors associated with game-related injury included female sex (IRR = 1.57; 95% CI: 1.18-2.08), previous injury (IRR = 1.46; 95% CI: 1.26-1.70) and lifetime concussion history (IRR = 1.41; 95% CI: 1.23-1.62). Goaltenders had a lower rate of injury (IRR = 0.54; 95% CI: 0.40-0.72) relative to forwards, as did players exposed to policy disallowing bodychecking in games (IRR = 0.44; 95% CI: 0.35-0.55). Female sex (IRR = 1.90; 95% CI: 1.10-3.28) and lifetime concussion history were also significantly associated with practice-related injury (IRR = 1.53; 95% CI: 1.08-2.18). CONCLUSIONS: Based on data from a large 5-year Canadian youth ice hockey longitudinal cohort, several factors associated with injury were identified. Future injury prevention strategies should consider age, sex, previous concussion and injury history, and body checking leagues. Future research in female youth ice hockey including female-only leagues should be a priority to inform prevention strategies in this understudied population.

Transcranial Direct-Current Stimulation Over the Primary Motor Cortex and Cerebellum Improves Balance and Shooting Accuracy in Elite Ice Hockey Players.

PURPOSE: To investigate the effects of transcranial direct-current stimulation (tDCS) applied over the primary motor cortex (M1) and cerebellum on balance control and shooting accuracy in elite ice hockey players. METHODS: Twenty-one elite ice hockey players underwent anodal tDCS over the M1 (a-tDCSM1), anodal tDCS over the cerebellum (a-tDCSCB), concurrent dual-site anodal tDCS over the M1 and the cerebellum (a-tDCSM1+CB), and sham stimulation (tDCSSHAM). Before and after receiving tDCS (2 mA for 15 min), participants completed an ice hockey shooting-accuracy test, Pro-Kin balance test (includes stance test and proprioceptive assessment), and Y-balance test in randomized order. RESULTS: For static balance performance, the ellipse area in the 2-legged stance with eyes open and the 1-legged stance with the dominant leg significantly improved following a-tDCSM1, a-tDCSCB, and concurrent dual-site a-tDCSM1+CB, compared with tDCSSHAM (all P < .05, Cohen d = 0.64-1.06). In dynamic balance performance, the average trace error of the proprioceptive assessment and the composite score of the Y-balance test with the dominant leg significantly improved following a-tDCSM1 and concurrent dual-site a-tDCSM1+CB (all P < .05, Cohen d = 0.77-1.00). For the ice hockey shooting-accuracy test, shooting-accuracy while standing on the unstable platform significantly increased following a-tDCSM1 (P = .010, Cohen d = 0.81) and a-tDCSCB (P = .010, Cohen d = 0.92) compared with tDCSSHAM. CONCLUSION: tDCS could potentially be a valuable tool in enhancing static and dynamic balance and shooting accuracy on unstable platforms in elite ice hockey players.

Describing the Flick Movement Kinematic Biomechanically and Investigating the Effect of Thrower's Ten Exercises in Underwater Hockey Players.

CONTEXT: Analyzing flick movement kinematics biomechanically is important to prevent sport-related injuries in underwater hockey players since the aquatic-based flick movement is completely different from land-based flick movements. The study aimed to describe the flick movement kinematic biomechanically in underwater hockey players. Moreover, this study further aimed to investigate the effect of the Thrower's Ten exercises on flick movement kinematics in underwater hockey players. DESIGN: Descriptive laboratory study. METHODS: Seventeen underwater hockey players (age: 26.2 [4.3] y; sports age: 6.2 [4.5] y) were included. First, 2 underwater cameras using motion capture video analysis MATLAB were used to biomechanically analyze the angular changes on the shoulder, elbow, wrist, and body while players were performing the flick movements. Players were then recruited to the Thrower's Ten exercise program for 6 weeks. Flick movement kinematics and flick-throwing distance were recorded at baseline and 6 weeks. RESULTS: The flick movement kinematic patterns demonstrated increased shoulder flexion (from 102.5° to 144.9°), wrist extension (from 9.5° to 10.8°), and upper-extremity rotation (from 5.7° to 56.8°) while decreased elbow extension (from 107.7° to 159.2°) from the stick met the puck until the competition of the movement. The Thrower's Ten exercises improved the elbow extension (P = .04), wrist extension (P = .01), body rotation (P < .001), and flick-throwing distance (P < .001) from baseline to 6 weeks. CONCLUSION: This study describes the underwater flick kinematic technique biomechanically and interprets preliminary findings for the first time. Thus, 6 weeks of Thrower's Ten exercise program provides more body muscle movements than the smaller ones during the flick movements and higher flick-throwing distance in underwater hockey players.

Relationships between sprint skating performance and insole plantar forces in national-level hockey athletes.

BACKGROUND: Sprint skating is essential for competitive success in hockey. Previous studies have highlighted various measures of lower-body strength and power as key factors influencing sprint performance. However, while these studies have indicated a significant association between the ability to exert greater force and impulse into the ice surface, and the capacity to achieve faster sprint skating speeds, the direct relationship between these factors remains largely inferred. RESEARCH QUESTION: What are the relationships between insole plantar force variables, sprint skating performance, and their association with physical capacity measures, in national-level male hockey athletes? METHODS: Athletes (n=13) performed 25 m sprint skating trials with insole force sensors and completed: ankle dorsiflexion and hip abduction range-of-motion (ROM), countermovement jump (CMJ), seated single-leg jump, and 10-5 repeated-hop test (RHT) assessments. RESULTS: Relationships were assessed using Kendall's Tau rank correlations (τ), with significant relationships identified between mean relative weight acceptance impulse [WAI] and 0-5 m (τ=0.47) and total distance (τ=0.46) times. Additionally, significant associations were observed between mean relative WAI and: CMJ relative eccentric deceleration impulse (τ=0.44), CMJ eccentric peak velocity (τ=-0.46) and RHT concentric impulse (τ=-0.56). Finally, significant relationships were identified between mean relative PI for all strides and the 10-20 m split, with peak velocity (PV) (τ=-0.58 to -0.73); and between ankle dorsiflexion ROM and PV (τ=-0.57). SIGNIFICANCE: Athletes with faster initial acceleration and overall sprint performance times demonstrated lower relative WAI during their strides and employed a jump strategy that optimized concentric impulse with a rapid eccentric phase. To attain a high PV the athletes appeared to require a stride that maximized glide and minimized vertical force, with greater ankle dorsiflexion ROM potentially facilitating this.

Return to Play After Arthroscopic Management of Rotator Cuff Tears in Professional Athletes of Contact Sports.

Background: Rotator cuff tears are rare injuries in professional athletes who participate in contact sports, and limited data exist to guide players and team physicians regarding outcomes after surgical management. Purpose: To report the outcomes and return-to-play rates of professional contact sport athletes who underwent arthroscopic management of rotator cuff tears. Study Design: Case series; Level of evidence, 4. Methods: All professional athletes of contact sports who underwent arthroscopic management of a rotator cuff tear between 2002 and 2019 at the institution were identified. Patient information collected were age, sport, position, date of injury, date of surgery, and time to return to play; surgical data included tear size, acuity, pattern, and procedure performed. The primary outcome measure was the ability to return to play and the number of games played after surgery. Results: Overall, 10 rotator cuff tears in 9 professional athletes (8 tears in football players and 2 tears in hockey players) were identified; 9 of the tears were full-thickness tears that underwent arthroscopic single-row repair, while 1 was a partial tear that was debrided. Of the 9 athletes, 8 were able to return to play at the same level, at a mean time of 9.5 ± 4.3 months. The mean playing time after surgery was 32 ± 25 games (2.7 ± 2 seasons) for the football players and 22 games (1 season) for the hockey player who returned. Postoperative imaging was available in 8 of the 10 tears, and 7 of 8 (88%) demonstrated a healed repair. One football player and 1 hockey player with large (>3 cm) full-thickness tears did not return to play. The mean age of these players was 34.5 years and both had >10 years of professional playing experience.≥. Conclusion: The study findings demonstrated that the majority (80%; n = 8) of the professional athletes in contact sports in this series were able to return to play at the same level after arthroscopic management of a symptomatic rotator cuff tear.

Dual career in sport and non-sport work: Exploring experiences of North American professional female ice hockey players.

Grounded in role strain theory, this study explored the dual career experiences of North American female ice hockey players who were also involved in full-time non-sporting work, focusing on factors that produced and reduced their role strain. We interviewed ten professional ice hockey players who held full-time non-sport jobs at the time of their interview. Our reflexive thematic analysis revealed that the multitude of factors leading to role strain among professional female working-athletes were notably significant, spanning societal expectations and environmental complexities. The imposition of the superwoman persona, demanding excellence in both hockey and work roles, combined with inconsistent expectations from professional and athletic supervisors intensified stress and undermined well-being. The study's findings emphasize the need for robust support systems and adaptive strategies, such as effective communication, careful planning, and proactive self-care, which can mitigate these pressures. Furthermore, the athletes' narratives revealed a pressing call for empathy and flexibility from coaches, employers, and the broader sports community, suggesting that improvements in these areas could enhance the professional and personal experiences of these working-athletes. The findings provide valuable insights into the challenges faced by dual career female athletes, as well as current strategies aimed at supporting and enhancing their experiences. Furthermore, these results deepen our understanding of how professional female athletes in North America can achieve greater well-being by addressing the factors that produce and reduce role strain factors.

Inter-Segment Coordination of Male and Female Collegiate Ice Hockey Players During Forward Skating Starts.

Purpose: Coordination in ice hockey skating has been minimally investigated, particularly in females. The objective was to compare lower-extremity inter-segment coordination of collegiate male and female ice hockey players during forward skating starts. Methods: 3D kinematic data were collected on collegiate male (n = 9) and female (n = 10) participants during accelerative steps. Continuous relative phase (CRP) was calculated for shank-sagittal/thigh-sagittal, shank-sagittal/thigh-frontal, and foot-sagittal/shank-sagittal segment pairs across 2.5 strides on each side. Principal component analysis (PCA) extracted features of greatest variability of the CRP and relationships between principal components and sex were investigated using hierarchical linear model. Results: Males demonstrated more out-of-phase coordination (higher CRP) for side one (p = .01) and side two (p < .01) shank-sagittal/thigh-sagittal as well as side one shank-sagittal/thigh-frontal (p < .01) segment pairs throughout each step. Females demonstrated a greater change in CRP from late stance/early swing to late swing/early stance on side two for shank-sagittal/thigh-frontal segments (p < .01). For side two shank-sagittal/thigh-frontal segments, faster males utilized more out-of-phase coordination throughout each step whereas faster females utilized more in-phase coordination (p < .01). Conclusion: Males and females may employ different coordinative strategies to achieve faster skating speeds. Males tend to utilize more out-of-phase coordination of the shank and thigh throughout strides, although coordinative differences of the shank and foot were not found between sexes. Further investigation is needed to examine the relationship between lower limb strength and coordination as well as the effect of targeted training protocols on lower extremity coordinative patterns.

Factors that influence field hockey footwear selection: An online survey.

BACKGROUND: Little is known about factors that influence footwear selection by field hockey players. METHODS: An online survey was used to collect data on participant demographics and physical characteristics, factors influencing footwear selection, perceptions regarding footwear design features on injury and performance, and experiences regarding usability. Nominal and ordinal data were described as absolute frequencies and relative frequencies. Free text responses were analysed using content analysis. Sex-related differences in quantitative and qualitative data were explored. RESULTS: A total of 401 hockey players completed the survey. Participants reported that fit, comfort, support, and cushioning were the most important factors when selecting hockey footwear. Most hockey players believed that stud design could influence athletic performance (65%) and injury risk (63%) but reported having no preference on outsole design or stud shape. Most participants (63%) used hockey-specific footwear, but 46% of female hockey players did not, with 40% using trail running footwear instead. Qualitative analysis revealed that hockey players, particularly female participants, encounter difficulties finding properly fitting footwear. They desire more options for wide or narrow feet and face challenges in accessing suitable hockey shoes due to limited choices and availability. CONCLUSIONS: With over a third of field hockey players not using hockey-specific footwear, future research should attempt to understand the reasons and assess the impact of different footwear features on comfort, performance, injury risk, and usability.

Development and experiences of an internet-based acceptance and commitment training (I-ACT) intervention in ice hockey players: a qualitative feasibility study.

Internet-based psychological interventions have increased the accessibility of evidence-based treatments in clinical psychology but are still an unexplored delivery format in sport psychology research. This study describes the development and evaluates the experiences of an internet-based acceptance and commitment therapy/training (I-ACT) intervention in ice hockey players focusing on performance enhancement and a sustainable sport participation. I-ACT consisted of seven weekly modules and the feasibility of the intervention was investigated using a qualitative research design. Four national level ice hockey players took part of I-ACT and were interviewed about their experiences using a semi-structured protocol. Interview transcripts were analyzed using qualitative content analysis. Findings suggest that the content of I-ACT was comprehensible, relevant, and that it was possible to put the psychological skills into practice. I-ACT was described as helpful to the ice hockey players either in their sport performance or in their life outside of sport. The internet-format was generally perceived as positive, flexible, and a feasible option for delivering psychological interventions in an elite sport context. Some concerns were raised regarding the timing of the intervention at the end of the season, and some players also wished for more time to complete I-ACT. It was also expressed that some of the exercises could have been better adapted for goaltenders. Further trials are needed to evaluate the effects of I-ACT on performance and mental health outcomes in various sport populations using robust quantitative research methodology. Internet-based psychological interventions are a potential future opportunity to make evidence-based practices more accessible for athletes.

Bone Mineral Density in Field Hockey Players: A Systematic Review.

The aim of this study was to carry out a systematic review to compare and analyse the bone mineral density of field hockey players of both sexes and of different ages, with other sports and with a sedentary population. The search process was carried out using the PubMed, SPORTDiscus, Web of Science and Scopus databases. The search ended on 18 March 2024. We selected articles in which a comparison was made of bone mineral density of the whole body, lumbar spine, femoral neck, arms and legs, among field hockey players, and/or with other sports and/or with a sedentary population. The systematic review followed the guidelines described in the 2020 PRISMA statement. The initial search identified 220 articles. After applying the inclusion and exclusion criteria, the search was narrowed down to seven articles in total. It was observed that the field hockey group had better bone mineral density values than sedentary population and the low-impact sports population. Basketball players had better whole body and leg bone mineral density values than field hockey players. Causality could not be established due to the cross-sectional nature of the included studies. The better bone mineral density values in field hockey players compared to the sedentary population may be because people who participate in impact sports have a better bone mineral density. The differences in bone mineral density between field hockey and low-impact sports could be related to a lower impact during their practice in these disciplines.

Analysis of Player Performance and Financial Costs Associated With Implementation of an Updated National Hockey League Concussion Protocol: A Retrospective Comparative Study.

Background: An updated National Hockey League (NHL) concussion protocol (NHLCP) was established in the 2016-2017 season to mitigate the negative outcomes of sport-related concussions. However, few studies on the effects of implementing the NHLCP have been performed. Purpose: To define concussion incidence and investigate differences in NHL player performance after a concussion during periods before and after NHLCP implementation and assess the financial impact on NHL teams associated with NHLCP implementation. Study Design: Cohort study; Level of evidence, 3. Methods: This was a retrospective review of NHL players who sustained a concussion before (2000-2001 to 2015-2016 seasons) and after (2016-2017 to 2020-2021 seasons) implementing the NHLCP (pre-NHLCP and post-NHLCP groups). For each group, multiple performance metrics-including 30 days, 1 season, and 3 seasons before and after concussion-were compared for both groups. Return to play, total concussion cost, and association of return to play with cost were investigated using regression analysis. Results: A total of 452 players (423 skaters, 29 goalies) sustained concussions during the study period, including 331 players (315 skaters, 16 goalies) in the pre-NHLCP group and 121 players (108 skaters, 13 goalies) in the post-NHLCP group. For both groups, no significant differences in standard performance were observed during the 30-day and 1-season periods before and after concussion. The mean return to play was significantly higher in the pre-NHLCP group than in the post-NHLCP group (20.1 vs 15.7 days; P = .022). The mean adjusted player salary was not different between groups; nonetheless, the mean adjusted replacement player salary was significantly higher in the post-NHLCP group ($744,505 vs $896,942; P = .032). The mean cost of time missed did not differ between groups. The mean return to play time significantly decreased over the entire study period (R2 = 0.33; P = .005), and the mean return to play time was positively associated with cost R2 = 0.215; P = .030). Conclusion: Concussion incidence did not change after implementation of the updated NHLCP; nonetheless, players had significantly less missed time from injury after protocol implementation. Changes in player performance 30 days and 1 year before and after concussion injury were not different before and after NHLCP implementation. No differences were found in the financial cost of concussions between the pre- and post-NHLCP groups, and missed time was significantly correlated with mean cost from missed time.

Analysis of Injuries in the Swiss U20 Elite Ice Hockey Season 2019/2020-A Retrospective Survey.

(1) Background: In Switzerland, there is little data on injury characteristics in elite ice hockey players aged under 20 years (U20 Elite juniors). This study aimed to determine the injury rate and type of injury in Swiss U20 ice hockey players. (2) Methods: The present study was carried out in a retrospective, non-experimental design using an online questionnaire provided to the 314 elite players of the 12 Swiss U20 Elite ice hockey teams. The injury rate, rate ratios, injury location, type and severity of injury, and injury mechanism were reported. (3) Results: Seventy-three athletes from 11 teams volunteered (response rate = 24%). A total of 30 out of 45 recorded injuries led to time loss in practice and competition. Injury occurred once or twice during the 2019/2020 season. For each player, the injury rate was 0.66 per 1000 practice hours and 2.98 per 1000 competition hours (injury rate ratio = 4.5). The head/neck region was the most common injury location (45.5%). (4) Conclusions: Knowledge of injury characteristics in ice hockey is necessary for meaningful injury management and injury prevention. The results of the present study provide information on the injury rate, location, types, severity, and mechanism in elite Swiss U20 ice hockey players. Most injuries result from contact with another player. More strict sanctioning for irregular behavior and fair play can serve as preventive measures. Further studies should examine different preventive measures such as wearing full-face coverage.

An in-depth analysis of wound incidence and injury status among professional athletes: A comprehensive review.

This review aims to synthesize current knowledge on the incidence, characteristics and management of wounds and injuries among professional ice hockey athletes, with the specific focus on the emerging population of Chinese female players. An extensive literature search was conducted across several databases to gather data on injury patterns and wounds, causes, severity and prevention strategies in ice hockey. Special attention was given to studies involving female athletes and unique challenges faced by players in developing regions like China. The review also examined the impact of training modalities, protective equipment and medical interventions on injury rates. The findings reveal a significant seasonal fluctuation in wound incidence, with marked reduction following the preseason period. This trend underscores the effectiveness of adjusted training programmes and essential role of medical teams in injury prevention and rehabilitation. Analysis did not show significant difference in wound rates between technical and physical training sessions, suggesting that injuries are pervasive risk across all training activities. Skating, collisions and inadequate warm-ups were identified as the leading causes of wounds, highlighting areas for targeted preventive measures. The distribution of wounds across various body regions pointed to knee, lower back and wrist as the most vulnerable sites, necessitating focused protection and training adjustments. Ice hockey, particularly among female athletes in China, presents complex injury landscape characterized by the wide range of wounds. The study emphasizes the necessity of comprehensive, multidisciplinary approach to injury prevention that includes training modifications, enhanced protective gear and strategic medical oversight. By addressing the specific causes and patterns of injuries identified, stakeholders can better protect athletes from the inherent risks of the sport, promote safer play and extend career longevity.

A essência da contradição entre o tratamento fragmentado dos conteúdos da categoria Hóquei 11-12 anos e a necessidade de uma visão teórico-metodológica que favoreça a estruturação coerente entre o carácter desenvolvimental das componentes da preparação dos jogadores de hóquei e da processo de ensino-aprendizagem deste esporte. O potencial instrutivo e educativo dos conteúdos foi defendido como forma de alcançar o elo de unidade entre o cognitivo e o afetivo na metodologia que contribui para a melhoria da sua estruturação, através de procedimentos didáticos apoiados na aprendizagem desenvolvimental e nas particularidades do desporto. A aplicação da metodologia, a partir da experiência pedagógica formativa, permitiu avaliar a sua viabilidade e funcionalidade, sendo evidente a sua eficácia no alcance dos objetivos estabelecidos.

The research is aimed at resolving insufficiencies in the treatment of content in the teaching-learning process of Field Hockey, in the 11-12-year-old category; consequently, the objective was set to develop a methodology for its didactic procedure. From a population of 18 teachers, a sample of 12 was intentionally selected; and from 168 hockey players, 72 were chosen. Methods and techniques such as document analysis, observation, interview, formative pedagogical experiment and critical opinion workshops were used. It was resolved the essence of the contradiction between the fragmented treatment of the contents of Hockey category 11-12 years and the need for a theoretical and methodological vision that favors coherent structuring between the developmental nature of the components of hockey players ` preparation and those of the teaching-learning process of this sport. The instructive and educational potential of the contents were argued as a way to achieve the link of unity between the cognitive and the affective in the methodology that contributes to the improvement of its structuring, through didactic procedures supported by developmental learning and the particularities of sport. The application of the methodology, from the formative pedagogical experiment, allowed its feasibility and functionality to be assessed, and its effectiveness in achieving the established goals was evident.
