Soccer Injuries in Female Youth Players

A cross-sectional survey of injuries among female youth soccer players found 44.6% (95% confidence interval 34.9%–54.8%) had ever been injured. The injury incidence rate for the current season was 2.2/1000 soccer exposure hours (95% CI 1.5–3.1). Future studies should evaluate modifiable risk factors in youth to identify injury prevention strategies.     

Health and safety implications of injury in professional rugby league football

BACKGROUND: Professional sport is characterized by high injury rates but is also covered by health and safety legislation. AIM: To examine the incidence of injury in professional rugby league as defined by the Reporting of Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR 95). METHODS: All injuries received during playing and training to both first-team and 'academy' (<19 years old) players during two playing seasons at one professional club were recorded. The length of time a player was unable to take part in full training and playing was used as a measure of severity. Injuries were classified into minor injuries (0-3 days), over 3 day injuries or major injuries, in which the final two categories corresponded with RIDDOR 95. RESULTS: Thirty-two per cent (95% confidence interval=26-39%) of all injuries received satisfied the RIDDOR 95 criteria. The overall injury rate was 8.5 per 1000 h (7.2-9.9) for the first team and 4.1 per 1000 h (3.2-5.4) for the academy team. During match play the first-team injury rate was 157.7 per 1000 h (133.5-185.1) and 67.7 (51-81.1) for the academy team. Training injury rates were lower, at 0.5 per 1000 h (0.2-1.0) and 0.3 per 1000 h (0.1-0.8), respectively. CONCLUSION: The injury rate for professional rugby league is much higher than reported in other high-risk occupations such as mining and quarrying. The large differences in injury rates between first and academy teams have implications for young players likely to progress to first-team status.     

The Effect of Carbohydrate Ingestion on Performance during a Simulated Soccer Match

Aim: This study investigated how performance was affected after soccer players, in a postprandial state, ingested a 7% carbohydrate (CHO) solution compared to a placebo (0% CHO) during a simulated soccer match. Methods: Using a double-blind placebo-controlled design, 22 trained male league soccer players (age: 24 ± 7 years, wt: 73.4 ± 12.0 kg, VO₂max: 51.8 ± 4.3 mL O₂/kg/min) completed two trials, separated by 7 days, during which they ingested, in random order, 700 mL of either a 7% CHO or placebo drink during a simulated soccer match. Ratings of perceived exertion (RPE), agility, timed and run to fatigue were measured during the trials. Results: Change in agility times was not altered by CHO vs. placebo ingestion (0.57 ± 1.48 vs. 0.66 ± 1.00, p = 0.81). Timed runs to fatigue were 381 ± 267 s vs. 294 ± 159 s for the CHO and placebo drinks, respectively (p = 0.11). Body mass modified the relationship between time to fatigue and drink ingestion (p = 0.02 for drink × body mass), such that lower body mass was associated with increased time to fatigue when the players ingested CHO, but not placebo. RPE values for the final stage of the simulated soccer match were 8.5 ± 1.7 and 8.6 ± 1.5 for the CHO and placebo drinks respectively (p = 0.87). Conclusions: The group data showed that the 7% CHO solution (49 g CHO) did not significantly improve performance during a simulated soccer match in league soccer players who had normal pre-match nutrition. However, when adjusting for body mass, increasing CHO intake was associated with improved time to fatigue during the simulated soccer match.     

Concussion incidences and severity in secondary school varsity football players

The head coaches and players of 103 secondary school football teams in Minnesota were asked to respond to mail questionnaires. Information about injury incidence and concomitant health care provision was elicited. Responses from 3,063 players (81 per cent) yielded a total injury rate of 78 injuries/100 players; 19/100 players reported a concussion experience characterized by loss of consciousness and/or loss of awareness. Of the players who experienced a loss of consciousness, 69 per cent were returned to play the same day. Persistent concussion symptoms were reported as long as six to nine months following the end of the season; six cases involved permanent disabilities. Continued use of illegal techniques of butt-blocking and face-tackling by as many as 40 per cent of the players was associated with apparent increased risks of concussions and concussion symptoms. Players with a prior history of loss of consciousness had a risk of loss of consciousness four times that of the player without a prior history.     

Factors related to return to play after knee injury in high school football athletes

Purpose

American football is played by over 1 million high school athletes in the United States, and knee injuries are the third most common injury. The purpose of this study is to identify factors that influence return to play after knee injuries in high school football athletes and whether return to play differs for varsity and nonvarsity football players.

Changes in sports injuries to children between 1983 and 1998: comparison of case series

BACKGROUND: Sports injuries sustained by children are worrying because they prevent and deter participation in physical activity. Before we can address such injuries we need to understand the size of the problem and whether there have been changes in occurrence. A study of sports injuries to children, carried out in a Cardiff Accident and Emergency department in 1983, provided the data against which to compare data gathered in 1998. METHODS: Data on all sports injuries to children aged 16 and under treated between September and December 1998 were compared with those reported for the same hospital, age group, injury and period in 1983. RESULTS: A total of 953 injuries were treated in 1998, representing an increase of 54 per cent [95 per cent confidence interval (CI) 44-64 per cent]. The male:female distribution remained constant and the majority of injuries were due to rugby and soccer. The number of females injured playing rugby and soccer increased and a wider range of sports led to injuries for both males and females. Amongst 10-15-year-olds injury risk increased from 1 in 78 for boys in 1983 to 1 in 22 in 1998 (p < 0.0001). For girls, the increase was from 1 in 117 to 1 in 55 (p < 0.0001). The number of soccer- and rugby-related fractures increased by 52 per cent (95 per cent CI 22-87 per cent). CONCLUSIONS: Sports injury rates have increased considerably over 15 years. With minimal population change, little variation in minor injuries and only small improvements in data capture, the main reason for change appears to be increased participation.     

Ramadan Nutritional Strategy: Professional Soccer Player Case Study

The period of Ramadan induces changes in the usual eating patterns of individuals. During this period, Muslims must abstain from drinking and eating from dawn to dusk. Therefore, some research conducted on professional soccer players has observed that during and/or after Ramadan, performance, running speed, agility, dribbling speed, and endurance and/or skill performance in athletic events may be negatively affected by Ramadan intermittent fasting (RIF). The objective of this study was to analyze the influence of a dietary plan during RIF on performance and body composition in a professional soccer player. A 20-year-old elite player (86.0 kg, 188.5 cm) followed a dietary-nutritional plan with an isocaloric diet and was supplemented with glycerol. The athlete’s strength and power in the lower limbs was assessed by performing a countermovement jump (CMJ) and Abalakov vertical jump (ABK) before and after Ramadan. After nutritional planning, the patient’s body composition improved in terms of fat loss (6.61 to 5.70%) and muscle mass gain (50.26 to 51.50%). In addition, this translated into improvements in performance tests, both in the CMJ (36.72 to 40.00 cm) and ABK (39.16 to 49.34 cm). In conclusion, during a period of fasting, personalised nutritional planning and an appropriate supplementation and rest protocol can improve the body composition and performance of soccer players.     

Cervical spinal cord injury in rugby union and rugby league: are incidence rates declining in NSW?

OBJECTIVES: To estimate trends in incidence rates of rugby code-related severe cervical spinal cord injuries in New South Wales (NSW) from 1986 to 2003. To evaluate the Australian Spinal Cord Injury Register (ASCIR) for injury surveillance by comparison with two published studies. METHODS: Data were cases of complete and incomplete tetraplegia in rugby union and rugby league admitted to the two spinal units in NSW. Trends in incidence rates were estimated using Poisson regression modelling. RESULTS: There was a small, non-significant decline from 1986 to 2003 in the incidence rate of tetraplegia in rugby union (9.8 vs. 6.1 per 100,000 player-years; p = 0.378) and rugby league (2.3 vs. 1.6 per 100,000 player-years; p = 0.564). The most common causes of injury were scrums for rugby union (35%) and tackles for rugby league (78%). This did not change over time (rugby union, p = 0.118; rugby league, p = 0.288). The ASCIR identified more cases of tetraplegia than insurance claims data and at least 75% of the cases ascertained by medical record review. CONCLUSIONS: There remains an urgent need to further improve safety in rugby union and rugby league. Scrummage in union and tackles in league remain the leading causes of tetraplegia. Rates of tetraplegia were significantly higher and more variable in rugby union than in rugby league. IMPLICATIONS: The ASCIR is a useful tool to monitor trends in spinal cord injury incidence in both rugby codes. Its potential value is constrained by the lack of accurate estimates of player numbers.     

Occupational eye injuries: a continuing problem

Background Ocular trauma is a worldwide cause of visual morbidity,a significant proportion of which occurs in the workplace. Thisis largely preventable with the use of protective eyewear andstrict compliance. Aim To analyse the type of occupational eye injuries that occurand to document the use of eye protection in patients presentingto a UK district general hospital. Methods A pilot retrospective case note analysis of all ocularinjuries seen in one calendar month was performed. A prospectivesurvey of consecutive occupational ocular injuries presentingto this district general accident and emergency (A&E) departmentover a 2-month period was then carried out. Demographics, aetiology,eye protection usage and clinical details were recorded andanalysed. Results Of all eye patients attending this A&E, 31% (87/283)were due to occupational eye injuries. Of 55 prospectively reviewedpatients with occupational eye injuries, the majority had minorinjuries. Of the cases where eye protection was recorded, 56%(18/32) were not wearing any protection and 44% (14/32) woreeye protection at the time of injury. Conclusions Occupational eye injuries are a commonly seen ocularcomplaint in the A&E department. Provision of appropriateeyewear protection and worker education is required to minimizethe incidence of ocular injury in the workplace.     

Injury risk in men's Canada West University football

Injury and participation information was collected over 5 years (1993-1997) on varsity men's football players in the Canada West Universities Athletic Association. The locations of acute time-loss injuries or neurologic injures were coded as head and neck, upper extremity (shoulder to hand), or lower extremity (hip to foot). Poisson regression-based generalized estimating equations were used to estimate rate ratios and 95% confidence intervals. Injury rates were higher during games as compared with practice periods (for the head and neck, rate ratio (RR) = 9.75 (95% confidence interval (CI): 7.50, 12.67); for upper extremities, RR = 5.76 (95% CI: 4.46, 7.45); and for lower extremities, RR = 7.06 (95% CI: 6.03, 8.25)). In dry-field game situations, head and neck injury rates were 1.59 times higher on artificial turf than on natural grass (95% CI: 1.04, 2.42). Lower extremity game injury rates were higher on artificial turf than on natural grass under both dry (RR = 1.83, 95% CI: 1.35, 2.48) and wet (RR = 2.31, 95% CI: 1.18, 4.52) field conditions. Injury rates increased with every additional year of participation. Past injury increased the rate of subsequent injury. The effect of an artificial field surface may be related to infrequent use. Risk factors for injury included participation in a game, playing on artificial turf, being a veteran player, and having a past injury.     

Parental safety concerns – a barrier to sport and physical activity in children?

OBJECTIVE: To examine the extent to which parents and carers perceive injury and safety risks as serious enough to prevent or discourage their children, aged 5-12 years, from participating in sports/physical activity and to identify factors that influence these perceptions. METHODS: An analysis of the 2001 New South Wales Child Health Survey. RESULTS: More than one-quarter of parents/ carers of active children aged 5-12 years reported discouraging or preventing children from playing a particular sport (34.7% for boys and 16.6% for girls) because of injury and safety concerns. In boys, the most frequently discouraged sport was rugby league (23.2%), followed by rugby union (7.5%) and Australian rules football (2.8%). Among girls, the most frequently discouraged activities were rollerblading (2.7%), rugby league (2.3%) and soccer (2.1%). Multivariate analysis shows that factors independently associated with parents' decision to prevent/discourage their child from engaging in sport/physical activity include their child's age and gender, language spoken at home, presence of disability, and the respondent's relation to the child. CONCLUSIONS AND IMPLICATIONS: Efforts need to be made to modify some sports/ activities, such as football codes, in order to minimise injury and to ensure that children continue enjoying their favourite activity well into adulthood. Guidelines designed to promote physical activity among children and young adolescents need to take into account parental concerns regarding the associated risk of injury.     

Doping practices and behaviours among Ivorian soccer players

We have conducted a survey of doping among soccer players in C?te d'Ivoire with a representative sample of 150 soccer players who filled out an anonymous questionnaire. The aim of this survey was to get a clearer picture of doping in Ivorian soccer in order to suggest preventive actions against doping. The results of this study showed that doping was known by the Ivorian soccer players; about 18.7% admitted to the use of doping substances, 42% recognised that they felt tempted by doping, while 38% knew another soccer player who had already used a doping substance. Government and sports organisations should recognize the importance of education and information in the antidoping campaign and agree on effective preventive as well as repressive strategies.     

Epidemiology of musculoskeletal injuries among high school cross-country runners

To determine the incidence of lower-extremity injury among high school cross-country runners and to identify risk factors for injury, the authors prospectively monitored a cohort of 421 runners competing on 23 cross-country teams in 12 Seattle, Washington, high schools during the 1996 cross-country season. Collected were daily injury and athletic exposure (AE) reports, a baseline questionnaire on prior running and injury experience, anthropometric measurements, and coaches' training logs. The overall incidence rate of injury was 17.0/1,000 AEs. Girls had a significantly higher overall injury rate (19.6/1,000 AEs) than boys did (15.0/1,000 AEs) (incidence rate ratio = 1.3, 95% confidence interval: 1.0, 1.6). Compared with boys, girls had significantly higher rates of injuries resulting in >or=15 days of disability. For the overall sample and for girls, Cox regression revealed that a quadriceps angle of >or=20 degrees and an injury during summer running prior to the season were the most important predictors of injury. For boys, a quadriceps angle of >or=15 degrees and a history of multiple running injuries were most associated with injury. Results suggest that the incidence of lower-extremity injuries is high for cross-country runners, especially girls. Preseason screening to determine risk factors should be examined as a preventive approach for identifying high-risk runners.     

Nutrient Intake and Food Habits of Soccer Players: Analyzing the Correlates of Eating Practice

Despite the impact and popularity of soccer, and the growing field of soccer-related scientific research, little attention has been devoted to the nutritional intake and eating habits of soccer players. Moreover, the few studies that have addressed this issue suggest that the nutritional intake of soccer players is inadequate, underscoring the need for better adherence to nutritional recommendations and the development and implementation of nutrition education programs. The objective of these programs would be to promote healthy eating habits for male and female soccer players of all ages to optimize performance and provide health benefits that last beyond the end of a player’s career. To date, no well-designed nutrition education program has been implemented for soccer players. The design and implementation of such an intervention requires a priori knowledge of nutritional intake and other correlates of food selection, such as food preferences and the influence of field position on nutrient intake, as well as detailed analysis of nutritional intake on match days, on which little data is available. Our aim is to provide an up-to-date overview of the nutritional intake, eating habits, and correlates of eating practice of soccer players.     

Stress hormone levels in saliva after shogi competition are modified by stress coping strategies

Proportionate mortality of Italian soccer players: Is amyotrophic lateral sclerosis an occupational disease?

Objectives: The objective of the study is to investigate the mortality experience of Italian soccer players and to discuss the findings in the light of possible long term effects of doping. Methods: Standardized proportionate mortality ratio (SPMR) and standardized proportionate cancer mortality ratio (SPCMR) were computed for 350 deceased subjects deriving from a list of about 24,000 active Italian soccer players from 1960 to 1996 in the three top leagues (A, B and C). Results: When considering SPMRs, there is a substantial adherence of observed to expected mortality, with the only exception of mortality for diseases of the nervous system (13 obs. vs. 6 exp.) mainly explained by an excess of amyotrophic lateral sclerosis (8 obs. vs 0.69 exp.). As far as SPCMRs are concerned, some digestive cancers (namely: colon cancer, liver cancer and pancreas cancer) show a doubled risk. Conclusions: A high risk for amyotrophic lateral sclerosis is observed among Italian soccer players. Epidemiological data on association between sport and Amyotrophic Lateral Sclerosis (ALS) are contrasting. On the basis of the overall available evidence we suggest a possible connection between dietary supplements or drugs used to enhance sporting performance and ALS pathogenesis. Further epidemiological studies are needed to confirm these specific mortality risks among soccer players.     

NekNominate: Social Norms,Social Media,and Binge Drinking

This study examines the social-media-based binge drinking game NekNominate and how this phenomenon is related to social norms. NekNominate is a game wherein players are nominated to film themselves “neking” or chugging copious amounts of alcohol or drinking alcohol in a novel or humorous manner. The player then nominates other players via social media who then have a specific timeframe in which they must complete their challenge or face ridicule. Health communication research on drinking behaviors has often looked at the role of social norms in determining these behaviors. News stories (n = 44) of NekNominate and tweets (n = 851) culled using the hashtag #NekNominate during three different time periods are analyzed to identify the normative forces at play in this recent phenomenon.     

Sport injury prevalence and risk by level of play and sports played among a representative population of French adolescents. A school-based study

BackgroundSports practice has both benefits and physical risks. In France, data related to adolescent sports injury are rare. The main purpose of this article is to study the prevalence and risk of injuries by level of play and sports in the southeast of France.MethodsData collection was conducted in French schools among adolescents in 2015 and 2017 (n = 1849; aged 14–19). Only sports players were included (n = 1366). Two level of play were created. The low-level group included adolescents playing sport either outside or within a club, at the local level of competition or below. The high-level group included adolescents playing sport within a club at the state (regional) level of competition or higher. Odds-ratios and their 95% confidence intervals adjusted for variables selected using stepwise regression procedures were calculated to determine the injury risk of high-level athletes compared with those at low-level, in each sport. We also calculated the injury risk of each sport compared to all the other sports, by level of play.ResultsIn almost all sports activities, the prevalence of injured athletes was higher in the high-level of play than in the low-level of play. The increase in injury risk was the highest in tennis, basketball, dance, athletics and volleyball. When comparing sports, at the lowest level, handball, boxing, soccer and gymnastics practitioners were more at risk than the rest of the sample. At the highest level of play, only basketball players were more at-risk. Dancing is the less dangerous sport in terms of injury outcome, regardless the level.ConclusionFrom the state level of competition, injury risk increases significantly across most of the sports. Meanwhile, differences appeared regarding the prevalence, severity and nature of the sustained injuries. It would be useful to perform such analysis on a greater sample size, ideally representative of the national population of adolescents.     

Hydration,Eating Attitudes and Behaviors in Age and Weight-Restricted Youth American Football Players

There is a paucity of research examining hydration and nutrition behaviors in youth American football players. A potentially unique risk factor are league restrictions based on weight (WR) or age (AR). The purpose of this study was to examine hydration status between WR and AR leagues. The secondary purpose was to describe eating patterns in players. An observational cohort design with 63 youth football players (10 ± 1 yrs, 148.2 ± 9.4 cm, 44.9 ± 15.3 kg) was utilized. Independent variables were league (AR (n = 36); WR (n = 27)) and activity type (practice (PX = 8); game (GM = 3)). Dependent variables were hydration status (urine osmolality; percent change in body mass (%BM)), eating attitudes (Children’s Eating Attitude Test (ChEAT-26)) and self-reported frequency of meals. On average, players arrived activity mildly hypohydrated (830 ± 296 mOsm/kg) and %BM was minimal (−0.1 ± 0.7%) during events. Players consumed 2 ± 1 meals and 1 ± 1 snack before events. The ChEAT-26 survey reported 21.6% (n = 8) of players were at risk for abnormal eating attitudes. Among these players, eating binges, vomiting, excessive exercise and drastic weight loss were reported. Youth American football players arrived activity mildly hypohydrated and consumed enough fluid during activity to maintain euhydration. Abnormal eating attitudes and the use of unhealthy weight loss methods were reported by some youth American football players.
