French preparticipation physical evaluation for children in 2020: What has changed?

At the end of 2019, there was discussion in France about whether to abolish the obligatory medical certificate of no contraindication for a minor to obtain a sports license. It was finally decided not to abolish the certificate, but it raises the question of which steps should be taken to assess the physical capacities of children. General practitioners or pediatricians are responsible for the preparticipation physical evaluation of children wishing to obtain a sports license, in particular involving over 20 mandatory consultations between the ages of 0 and 18. The purpose of the article is to propose a course of action to be taken considering the French legislation and general pediatric resources concerning the medical examination and warning signs that should lead to vigilance.

Youth Baseball Pitch Counts Vastly Underestimate High-effort Throws Throughout a Season.

BACKGROUND: The primary purpose of this study was to compare the number of pitches thrown by youth baseball players under the official league guidelines versus the number of "high-effort" throws recorded by a validated digital sensor worn by the players during a season. METHODS: In total, 11 and 12-year-old youth baseball players from a single league were provided an elbow sleeve and sensor to wear each time they threw a baseball for an entire baseball season. The sensor tracked total throws and pitch-equivalent high-effort throws for the season. Official pitch counts were collected at each game from the official scorekeepers. RESULTS: A total of 19 players participated in the study. The sensor-determined mean total throw count (1666.2±642.2) and mean high-effort throw count (576.9±329.3) per player were both significantly higher, P<0.0001 and P=0.02, respectively, than the mean official pitch count (168.1±122.4). CONCLUSIONS: Our findings demonstrate that youth players make significantly more total throws and high-effort, or pitch-equivalent, throws, than what is recorded by the official pitch counts. Further research is needed to determine a safe annual "throw count" for young throwing athletes and to determine which types of throws, in addition to pitches, put youth throwers at risk for injury. LEVEL OF EVIDENCE: Level IV.

Head impact exposure in youth football-Are current interventions hitting the target?

Restrictions on heading in youth football have been implemented in some countries to limit head impact exposure. However, current interventions remain poorly guided by evidence. Our objective was to quantify heading exposure in youth football, assessing the effects of sex and age. Football matches played during an international youth football tournament with no heading restrictions were directly observed, including players from both sexes (11-19 years). The elite senior level was included for comparison, using video analysis. All heading events were registered, classified, and assigned to individual players. Heading rates were calculated for each sex and age group. We observed a total of 267 matches, corresponding to 4011 player hours (1927 player hours for females, 2083 player hours for males). Males headed more frequently than females (2.7 vs 1.8 headers/player hour; P < .001). Heading rates increased with age (ANOVA, P < .001), approaching the elite senior level for players 16 years and older. There was substantial variation within teams for all age and sex groups, with the widest range (1-18 headers) observed for girls aged 19. Girls younger than 12 years had the lowest exposure, with an average of <2 players per team heading the ball, each with 1-2 headers. In conclusion, age and sex influence head impact exposure in youth football, and warrants careful consideration when introducing injury prevention measures. Males are more frequently exposed than females, heading rates increase with age, and there is substantial variation between players. Heading is a rare event in the youngest age groups, especially among females.

Exploring Coaches' Perceptions of Youth Sport Specialization: A Comparison of High School and Club Sport Contexts.

CONTEXT: Previous researchers have identified sport specialization as being associated with various negative outcomes (eg, overuse injuries and adverse psychosocial outcomes). However, little is known regarding how the underlying attitudes, beliefs, and values of sport stakeholders may be shaping this trend. OBJECTIVE: To examine the perceptions of coaches in the high school versus club sport setting and compare their attitudes and behaviors toward sport specialization. DESIGN: Cross-sectional survey. PATIENTS OR OTHER PARTICIPANTS: A total of 769 coaches (497 high school coaches, 272 club sport coaches). MAIN OUTCOME MEASURE(S): Participants completed a novel measure that surveyed their perceptions regarding various aspects of youth sport specialization. Additionally, each coach completed a questionnaire detailing his or her relevant demographic and sport background information. RESULTS: High school coaches and club sport coaches differed in their perceptions of sport specialization (t767 = 1.41, P < .001); club coaches (2.43 ± 0.25) were more likely than high school coaches (2.31 ± 0.21) to rate specialization as a positive, adaptive practice. The multiple linear regression equations for both the high school and club coaches indicated that no educational, experiential, or demographic factors predicted coaches' perceptions of specialization (P values > .05). CONCLUSIONS: Club sport coaches were more likely to possess attitudes in favor of sport specialization. Additionally, coaches' background characteristics did not predict their perceptions of specialization, suggesting that the competitive context itself (high school versus club) may be the most salient influencer of these perceptions. Athletes and sports medicine practitioners should be aware of the heightened expectation of specialized participation and resulting increased injury risk in these contexts. Pediatric sport researchers and practitioners should continue to explore how these different group perceptions manifest in participation behaviors and may link to overall athlete health, wellbeing, and development.

Health Consequences of Youth Sport Specialization.

Sport specialization is a training method now commonly used by young athletes who hope to achieve elite-level success. This may be defined as (1) choosing a main sport, (2) quitting all other sports to focus on 1 sport, and (3) year-round training (greater than 8 months per year). A number of sports medicine organizations have published recommendations based on the limited evidence available on this topic. The objective of this article was to perform a narrative review of the currently available evidence and sports medicine organizational recommendations regarding sport specialization and its effects on health to guide athletic trainers and sports medicine providers. To accomplish this goal, we conducted a narrative review of articles and position statements on sport specialization published from 1990 through 2018. Injury, overuse injury, serious overuse injury, and lower extremity injury were likely associated with higher degrees of sport specialization in various populations. Sports medicine organizations in general recommended against sport specialization in young athletes and instead promoted multisport participation for physical and psychological benefits. Few long-term data suggest that sport specialization has negative health-related quality-of-life consequences. Higher degrees of sport specialization likely pose risks of overuse injury; however, the age of specialization at which this risk occurs is not known. Because different populations and sports activities may put children at risk for certain injuries, future researchers should monitor large populations with sport-specific prospective active surveillance.

Proceedings from the Ice Hockey Summit III: Action on Concussion.

The Ice Hockey Summit III provided updated scientific evidence on concussions in hockey to inform these five objectives: 1) describe sport-related concussion (SRC) epidemiology, 2) classify prevention strategies, 3) define objective, diagnostic tests, 4) identify treatment, and 5) integrate science and clinical care into prioritized action plans and policy. Our action plan evolved from 40 scientific presentations. The 155 attendees (physicians, athletic trainers, physical therapists, nurses, neuropsychologists, scientists, engineers, coaches, and officials) voted to prioritize these action items in the final Summit session. 1) Establish a national and international hockey data base for SRC at all levels, 2) eliminate body checking in Bantam youth hockey games, 3) expand a behavior modification program (Fair Play) to all youth hockey levels, 4) enforce game ejection penalties for fighting in Junior A and professional hockey leagues, 5) establish objective tests to diagnose concussion at point of care (POC), and 6) mandate baseline testing to improve concussion diagnosis for all age groups. Expedient implementation of the Summit III prioritized action items is necessary to reduce the risk, severity, and consequences of concussion in the sport of ice hockey.

The Effect of Body Checking Policy Changes on Concussion Incidence in Canadian Male Youth Ice Hockey Players: A Critically Appraised Topic.

Clinical Scenario: Current studies have identified body checking as the most common cause of sports-related concussion in ice hockey across all divisions and levels. As a result, many hockey organizations, particularly in youth sports, have implemented rules making body checking to the head, face, and/or neck illegal. Such a rule, in Canada, makes age 13 the first age in which individuals can engage in body checking. Despite these changes, effectiveness of their implementation on the incidence of concussion in Canadian male youth ice hockey players remains unclear. Clinical Question: What is the effect of body checking policy changes on concussion incidence in male youth ice hockey players? Summary of Key Findings: Of the 3 included studies, 2 studies reported a decrease in the incidence of concussion once a body checking policy change was implemented. The third study showed an increase; however, it is important to note that this may be due, in part, to increased awareness leading to better reporting of injuries. Clinical Bottom Line: Current evidence supports a relationship between body checking policy implementation and decreased concussion incidence; however, more research is needed to understand the long-term implications of policy change and the effects in other leagues. In addition, further data are needed to differentiate between increased concussion incidence resulting from concussion education efforts that may improve disclosure and increased concussion incidence as a direct result of policy changes. Strength of Recommendation: Grade B evidence exists that policy changes regarding body checking decrease concussion incidence in male youth ice hockey players.

The effects of resistance training, overtraining, and early specialization on youth athlete injury and development.

INTRODUCTION: In 2014, 60 million youth ages 6-18 participated in some form of generalized athletics. Around 3.5 million children are injured annually participating in organized sport or recreational activities. While sound physical education can decrease the burden of youth sports injuries, the median annual physical education budget of $ 764 for USA elementary, middle, and high schools may not allow enough flexibility to apply evidenced-based guidelines. EVIDENCE ACQUISITION: The topics were selected after a careful review of the 2016 National Strength and Conditioning Association Position Statement on Long-Term Athletic Development. Articles used to summarize the topics were located by using and cross-referencing sources from this statement. PubMed searches were also conducted using the key words "youth sports injuries," "early sports specialization," "training and maturation," "training versus developmental stage," and "long-term athletic development." EVIDENCE SYNTHESIS: Youth resistance training has been shown to decrease not only the risk of injury, but also of the development of diabetes and metabolic syndrome. Adequate recovery time also decreases injury risk, and resources such as the RESTQ-Sport are available to help coaches identify stress-recovery imbalances, which can be detected two months before an athlete becomes overreached. Through early detection of overtraining, a significant proportion of overuse injuries can be prevented. Early specialization causes fewer muscle groups to be worked and increased repetition, theoretically increasing the risk of injury and early sport dropout. Prior to puberty, increased neuronal activation and adaptation can be achieved through focusing on agility, balance and coordination, thus taking advantage of increased synaptoplasticity. In these early years, neuronal stimulation is more important than muscle hypertrophy, which plays a greater role in athletic development after puberty. CONCLUSIONS: A substantial proportion of youth injuries are preventable. Coaches and physical educators who correctly understand and apply the principles outlined in this review can help youth under their supervision engage in healthy training for sport.

Non-sanctioning of illegal tackles in South African youth community rugby.

OBJECTIVES: The tackle event in rugby union ('rugby') contributes to the majority of players' injuries. Referees can reduce this risk by sanctioning dangerous tackles. A study in elite adult rugby suggests that referees only sanction a minority of illegal tackles. The aim of this study was to assess if this finding was similar in youth community rugby. DESIGN: Observational study. METHODS: Using EncodePro, 99 South African Rugby Union U18 Youth Week tournament matches were coded between 2011 and 2015. All tackles were coded by a researcher and an international referee to ensure that laws were interpreted correctly. The inter- and intra-rater reliabilities were 0.97-1.00. A regression analysis compared the non-sanctioned rates over time. RESULTS: In total, 12 216 tackles were coded, of which less than 1% (n=113) were 'illegal'. The majority of the 113 illegal tackles were front-on (75%), high tackles (72%) and occurred in the 2nd/4th quarters (29% each). Of the illegal tackles, only 59% were sanctioned. The proportions of illegal tackles and sanctioning of these illegal tackles to all tackles improved by 0.2% per year from 2011-2015 (p<0.05). CONCLUSIONS: In these youth community rugby players, 59% of illegal tackles were not sanctioned appropriately. This was better than a previous study in elite adult rugby, where only 7% of illegal tackles were penalised. Moreover, the rates of illegal tackles and non-sanctioned illegal tackles both improved over time. However, it is critical that referees consistently enforce all laws to enhance injury prevention efforts. Further studies should investigate the reasons for non-sanctioning.

Consistency and Variation in School-Level Youth Sports Traumatic Brain Injury Policy Content.

PURPOSE: The purpose of the study was to examine the consistency and variation in content of high school written traumatic brain injury (TBI) policies in relation to the three key tenets of youth sports TBI laws. METHODS: A content analysis was conducted on written TBI policies retrieved from 71 high schools currently participating in High School Reporting Information Online. Each policy was independently analyzed by two trained coders. The number and percent of the policies reflecting the three key tenets of state youth sports TBI laws were described and compared on policy enforcement (i.e., strictness of language), policy description (i.e., details and definitions of the requirements), and policy implementation steps (i.e., specific steps for implementing the requirements). Direct quotes were identified to support quantitative findings. RESULTS: All 71 high school TBI policies contained at least two of the three main TBI law tenets, where 98.6% (n = 70) included the return to play tenet, 83.1% (n = 59) included the removal from play tenet, and 59.2% (n = 42) specified the distribution of TBI information sheets to student-athletes and their parents. Nearly half of the policies (49.3%, n = 35) required parents' signature while only 39.4% (n = 28) required students' signature on the TBI information sheet. The language exhibited wide variance across the 71 TBI policies regarding policy enforcement, policy description, and policy implementation specifications. CONCLUSIONS: All 71 TBI policies covered at least two of the three youth sports TBI law tenets, but with considerable variation. Future research should assess variations by schools within the same state and their impact on TBI rates in school athletics.

Child and adolescent sports psychiatry in the US.

A positive youth sports experience is essential if an athlete is to develop a lifelong commitment to sport. Children enjoy play and adults can create opportunities for physical, emotional, and cognitive development through sport for all children. This article reviews the current state of youth sports in the US, highlighting some of the problems of the current model and efforts to transform and improve the youth sports experience in the US. The new model of youth sports emphasizes the importance of developing 'physical literacy' in all young athletes, increasing availability of recreational sports activities, providing quality coaching to all, improved sports safety, improved availability of sports venues for athletes at all levels, and at an affordable cost for all. The US Olympic Committee, following an innovative programme by USA Hockey, has developed and promoted the American Developmental Model to its component Sport National Governing Boards to improve the experience of young athletes. The sports-informed paediatric psychiatrist, knowledgeable about child and family development and aware of the local youth sports opportunities and challenges, is well prepared to advocate for a healthy and fun sport experience for every young athlete.
