Objective: To conduct a detailed analysis of hamstring injuries sustained in English professional football over two competitive seasons. Methods: Club medical staff at 91 professional football clubs annotated player injuries over two seasons. A specific injury audit questionnaire was used together with a weekly form that documented each clubs' current injury status. Results: Completed injury records for the two competitive seasons were obtained from 87% and 76% of the participating clubs respectively. Hamstring strains accounted for 12% of the total injuries over the two seasons with nearly half (53%) involving the biceps femoris. An average of five hamstring strains per club per season was observed. A total of 13 116 days and 2029 matches were missed because of hamstring strains, giving an average of 90 days and 15 matches missed per club per season. In 57% of cases, the injury occurred during running. Hamstring strains were most often observed during matches (62%) with an increase at the end of each half (p,0.01). Groups of players sustaining higher than expected rates of hamstring injury were Premiership (p,0.01) and outfield players (p,0.01), players of black ethnic origin (p,0.05), and players in the older age groups (p,0.01). Only 5% of hamstring strains underwent some form of diagnostic investigation. The reinjury rate for hamstring injury was 12%. Conclusion: Hamstring strains are common in football. In trying to reduce the number of initial and recurrent hamstring strains in football, prevention of initial injury is paramount. If injury does occur, the importance of differential diagnosis followed by the management of all causes of posterior thigh pain is emphasised. Clinical reasoning with treatment based on best available evidence is recommended.

Objectives: To conduct a detailed analysis of preseason football injuries sustained in English professional football over two competitive seasons. Methods: Club medical staff at 91 professional football clubs annotated player injuries. A specific injury audit questionnaire was used together with a weekly form that documented each club's current injury status. Results: 17% (1025) of the total number of injuries over the two seasons were sustained during the preseason, the mean number of days absent per injury was 22.3 days. Younger age groups (17-25 yrs) were more likely to sustain a preseason injury than more experienced players (26-35+) (p<0.01). There were relatively more "slight" and "minor" injuries (as defined in the methodology), overuse, and tendon related injuries sustained during preseason compared to the in season (p<0.01). The thigh (23%), knee (17%), and ankle (17%) were the most common locations for injuries during the preseason, there was a relatively greater number of lower leg injuries (15%) during the preseason (p<0.05). Achilles tendonitis was most prevalent in the preseason, with 33% of all Achilles related injuries sustained during this period (p<0.01). Muscle strains were the most common injury during preseason (37%). Rectus femoris muscle strains were observed twice as frequently during the preseason relative to the in season (p<0.01). Ligament sprains were the second most common injury during preseason (19%). Non-contact mechanisms were the cause of significantly more injuries during the preseason (p<0.01), with relatively more preseason injuries sustained while running or shooting (p<0.01). For 70% of the injuries reported during the preseason, the ground condition was described as dry. Conclusions: Players are at a greater risk of slight and minor injuries, overuse injuries, lower leg injuries (especially the Achilles tendon) and rectus femoris strains during the preseason period. Prevention of preseason injury is important to ensure availability of players for the commencement of the season and to decrease the risk of injury later in the season, we recommend the implementation of a risk management policy for this purpose. Areas requiring further investigation include methods of prevention for the common preseason injuries that have been identified, a detailed analysis of preseason and closed season training programmes, and a smaller study involving exposure data.

Aim: To conduct a detailed analysis of ankle sprains sustained in English professional football over two competitive seasons. Methods: Club medical staff at 91 professional football clubs annotated player injuries. A specific injury audit questionnaire was used together with a weekly form that documented each club's current injury status. Results: Completed injury records for the two competitive seasons were obtained from 87% and 76% of the participating clubs. Ankle ligament sprains accounted for 11% of the total injuries over the two seasons, with over three quarters (77%) of sprains involving the lateral ligament complex. A total of 12 138 days and 2033 matches were missed because of ankle sprains. More sprains were caused by contact mechanisms than non-contact mechanisms (59% v 39%) except in goalkeepers who sustained more non-contact sprains (21% v 79%, p<0.01). Ankle sprains were most often observed during tackles (54%). More ankle sprains were sustained in matches than in training (66% v 33%), with nearly half (48%) observed during the last third of each half of matches. A total of 44% of sprains occurred during the first three months of the season. A high number of players (32%) who sustained ankle sprains were wearing some form of external support. The recurrence rate for ankle sprains was 9% (see methodology for definition of reinjury). Conclusion: Ankle ligament sprains are common in football usually involving the lateral ligament complex. The high rate of occurrence and recurrence indicates that prevention is of paramount importance.

Numerous research studies document the negative mental health outcomes associated with the experience of childhood sexual abuse. In addition, factors such as one's relationship with the perpetrator and the severity of the abuse predict the likelihood of future mental health problems. Less attention, however, has focused on the age of the perpetrator, and recent years have seen an increased interest in children who display sexual behavior problems. College students completed measures of mental health functioning and retrospective reports of maltreatment histories. Participants were categorized as abused by an adult (n = 48), teenager (n = 39), or another child (n = 37), and non-abused (n = 219). Victims of abuse, regardless of perpetrator age, displayed higher levels of mental health problems than non-abused participants. There were no differences between the abused groups on any of the mental health outcomes; however, individuals who were abused by other children were less likely to label their experiences as abuse.
