IntroductionBasketball is one of the world’s most popular and widely viewed sports1. In Nigeria, it is the second most pop-ular sport after football2. It is widely played from the grass-root to the pro-fessional level. Despite the enormous growth in the game of basketball in Nigeria, there appears to be little at-tention in terms of player’s health even at the professional level.

The female basketball league in Nigeria is from March to November in three phases and in three dif-ferent regions of the country. The 2010–2011 league season just like the previous ones lasted for 30 days. Each phase ran for 10 days, with in-tervals between each phase. Five

matches were played each day, and all the teams were involved in all the matches each day of each phase. The three phases that spanned over a pe-riod of 8 months from March to No-vember were played in Akure, Abuja and Lagos respectively.

As a sport grows in the number of participants and intensity, so does the number of injuries3. Women’s sports, once dominated by a slow and defensive style, is now played with speed, precision and power; with these changes, increased injuries now occur4. Women’s basketball is a faster-paced game than it was several years ago5. Unfortunately, less atten-tion has been given to female players, especially when it comes to high-level participation, despite the increasing-ly engaging population in the sports6.

An important purpose of sports injury epidemiology is to supply knowledge on injuries that occur frequently and which have serious consequences, and to describe their aetiology in order to provide a basis for preventive measures7. However, such studies are globally limited on female basketball players. Thus, the conduction of epidemiological stud-ies has become critical for character-izing injuries in this sport8,9.

A number of such epidemiological studies have been conducted in the United States and other parts of the world on both male and female play-ers4–6,8–15. However, in Nigeria, de-spite increased participation in the sport and the importance of research in this area, only very few published studies directly relate to basketball injuries2,16,17, and no published stud-ies presently exist on professional female basketball players in Nigeria. Therefore, the purpose of this study

common types, followed by bruise/contusion (15, 13.9%) and cramp (9, 8.33%) during matches and trainings; dislocation (7, 6.50%), laceration (7, 6.50%) and head in-jury (4, 3.70%) were the least types of injuries sustained during match-es and training (Table 1). There was no significant difference in the frequency of injury occurrence for the different types of injuries sus-tained during matches and training (P = 0.330).

Body parts injuredRegarding the anatomical region, injuries predominantly occurred in the lower limbs, with the knee (29, 27.0%) and ankle (26, 24.1%) hav-ing the highest prevalence. The third most common body part injured was the wrist/hand (12, 11.1%). The least injured body part was the abdo-men (2, 1.9%) (Table 2).

Injury distribution by playing positionPoint guards sustained more injuries than players in other positions (14, 24.1%), closely followed by shoot-ing guard (12, 20.7%) and power forward players (12, 20.7%). Small forward had the least number of in-juries (9, 15.5%) (Table 3).

For the purpose of analysis, players who sustained injury and could not continue with play during either training or matches between 1 and 3 days were classified as minimal, 4–7 days as mild, 8–28 days as moderate and above 28 days as severe18.

Data analysisData are summarized using descrip-tive statistics of frequency, percent-age, mean, standard deviation and inferential statistics of chi-square. Level of significance was accepted at P < 0.05.

ResultsOut of the 120 copies of the question-naires distributed, 104 copies were returned by the players (aged 18.2 ± 2.66 years; range 14–28 years), giv-ing a response rate of 86.7%. A total of 108 injuries were sustained by 58 players (each player sustained at least one or more injuries) in the past 12 months, giving an overall injury prevalence of 55.8%. Also, a total of 54 time-loss injuries were reported by 36 players; giving a time-loss prevalence of 33.3%.

Types of injuries sustainedSprains (34, 31.5%) and strains (21, 19.4%) were found to be the most

was to investigate the pattern of in-juries in female players of the Nigeria Basketball League.

Materials and methodsThis work conforms to the values laid down in the Declaration of Helsinki (1964). The protocol of this study has been approved by the relevant ethical committee related to our in-stitution in which it was performed. All subjects gave full informed con-sent to participate in this study.

This study was a retrospective cross-sectional survey that involved all the professional female basket-ball players who participated in the 2010–2011 league season. Data were collected at the end of the league sea-son after the third phase of the na-tional league held at the National Sta-dium indoor games, Surulere, Lagos State, in November 2011. The female basketball league for the 2010–2011 season had 10 teams, and each team registered 12 players for the league season. A total of 104 out of the 120 basketball players consented to par-ticipate in this study.

The questionnaires were distrib-uted to all participating players reg-istered for the 2010–2011 Nigeria Female Basketball League either di-rectly at the hotels where they were lodged or through their coaches who also helped in retrieving question-naires. All players and coaches were informed about the aim of the study and anonymity of the data before questionnaires were distributed.

The research instrument used for the study was an injury question-naire adapted from previous local studies on basketball injury2,16. The questionnaire had two sections: sec-tion A included demographic data of the players which include their age, height, weight, team, and playing po-sition; section B recorded the total number of injuries sustained during the 2010–2011 league season, time-loss injuries and period of absence from matches and training, type of in-jury/injuries and body parts injured.

the lower limb. This study found in-juries involving the knee joint to be the most prevalent. The complexity of the knee joint structure and the multidirectional forces imposed on the knee joint during sporting activi-ties may explain why knee injuries are often more severe than injuries to other body regions. Factors that could predispose players to injuries include anatomical differences in structure, lower limb biomechanical differences and hormonal factors10,19. Although injury aetiology relates primarily to sport-specific activity, female athletes are at higher risk of knee injury than their male counter-parts in jumping and cutting sports20.

Sprain and strain were the most documented types of injury in con-gruence with most other studies8–16, which showed that ligament sprain and muscle/tendon strain were the most frequent injury diagnosis. Re-garding injury prevalence and play-ers’ positions in the court, point guards had the highest prevalence. This could be because the point guard position is a very crucial one and usually the most active player on the basketball court. The point guard is the playmaker and one in charge of controlling and distribut-ing the ball and making sure that the right players get the ball at the right time1.

Epidemiological studies in all cate-gories and levels of basketball are re-quired to assess the pattern of injury and identify risk factors associated with playing basketball. This study is the first cohort study on female bas-ketball players in Nigeria, and thus its findings may provide a platform for preparing preventive measures in the population studied. However, a limitation of the present study is that players themselves retrospectively documented injuries. We recom-mend more studies, especially pro-spective studies, for an accumulation of data that will help proffer objec-tive measures of injury prevention in basketball.

studied reported time-loss injuries of which most were mild. One out of three players losing play time for training and matches raises an alarm for concern and a need for appropri-ate intervention. Since most previ-ous studies available currently did not assess injury severity, it becomes difficult comparing our results with others in order to determine the pe-culiarity of the problem.

Our study found the lower limbs to be the most commonly injured body region (73.4%); this finding is con-sistent with previous studies on bas-ketball injuries2,4–6,8–16. However, in terms of the most commonly injured anatomical region in basketball, there are some controversies in literature on whether the knee or the ankle is the most frequently injured part of

Severity of injuriesTime-loss injuries were mostly mild (20, 37.0%) and moderate (18, 33.3%), accounting for 4–7 days and 8–28 days off play respectively. There was no significant difference between the severity of injuries dur-ing training and matches (P = 0.781) (Table 4).

DiscussionThe growth and popularity in basket-ball participation in Nigeria creates an urgent need for injury surveil-lance to identify potential avenues for injury prevention. This study showed an injury prevalence of 55.8% among female players of the Nigeria Basketball League, which indicates a substantially high preva-lence of injury. A third of the players

ConclusionThe prevalence of injury was con-siderably high among professional female basketball players in Nigeria, and one out of three players suffered a time-loss injury during a league season.

Furthermore, there is a pertinent need for more stud-ies relating to injury surveillance in basketball.
