Basketball has become one of the most popular sports in the world and has given us the pleasure of gushing over NBA stars such as O’neal, James, Curry and of course, the legendary Jordan. As a non-contact sport, basketball remained one of the safest sports ever played. However, as the sport seems to increase its popularity status; so did the injuries associated with the sport. Injuries most common to basketball are ankle sprains, knee injuries, lower back pains, facial and finger injuries as well as anterior cruciate ligament injuries.
In comparison with contact and other non-contact sports, basketball has been classified as one of the sports with a higher injury risk of injury and injury incidence . Because basketball is a sport that requires speed, strength and power to accomplish movements such as rebounds and jump-shots, one can presume that players are likely to suffer some injuries when performing these highly dynamic movements .
Weiss, KJ et. al  used the Oslo Sports Trauma Research Questionnaire (OSTRQ) to record the onset of overuse injuries for the ankle, knee and lower back in professional male basketball players. The author assessed the prevalence and severity of overuse injuries and also determined the efficacy of the questionnaire over one season. The authors found that severe knee overuse injuries were reported more than ankle and lower back injuries , suggesting injury prevention strategies may need to focus on the knee.
Another study showed the prevalence of injuries in female basketball players (19.5% ankle injuries, 20.6% knee injuries) and in male basketball players (28.4% ankle, 17.5 knee injury)  suggesting a higher injury risk in women than men. Zuckerman and his team  found that during practice, males had a higher rate of ankle injury compared to females while females have higher rate of overuse knee injuries curing practice. From these findings, one can assume that females are more at risk to knee injuries and male’s ankle injuries.
While the underlying causes of injuries are yet to be fully understood, some research has emerged to understand how these injuries occur. Ankle sprains may occur as an athlete lands on an opponent’s foot. Overuse knee injuries seem to be caused by overloading and previous injury. Interestingly, knee injuries are seen mostly in centre players than any other positions, suggesting that playing positions may be a risk factor .
The cause of overuse knee injuries and ankle sprains is still a puzzle that seems to have little pieces, at least for now. With that said, through injury surveillance and the identification of injury risk factors and further understanding how injuries occur, better injury prevention strategies can be formulated and implemented. Until then, sprains and pains remain a concern in basketball.

Soccer is arguably the most popular sport globally, with an estimated 200 million players worldwide (1). There are many health benefits of playing soccer, including reducing the risk of type 2 diabetes and hypertension (2). Despite its health benefits, soccer also poses a significant risk of injury (3), particularly to areas such as the knee, ankle and thigh (4). These injuries are largely attributed to insufficient warm-ups, muscle fatigue and imbalance (5). A study conducted on the incidence of soccer injuries, showed that 15-20 injuries occurred per 1000 hours of match play, in players above 15 years old (6).
Because of the high incidence of soccer injuries worldwide, an injury prevention strategy for amateur players was developed in 2006, called the FIFA 11+. The FIFA 11+ comprises of a simple warm-up routine consisting of 15 exercises, that soccer players are to perform for a minimum of 2 times per week. The warmup requires minimal equipment, is available online and can be performed within 10-15 minutes (7).
Does the warmup reduce injury risk?
This question was answered by conducting trials that implemented the FIFA 11+ intervention into real life practice. These trials were then analysed in systematic reviews. The studies selected for review were implemented in a range of locations including North America, Europe, Asia and Africa, and tested male and female amateur players, with ages ranging from 15-45 years (7–10).
Overall results showed that implementing the FIFA 11+ warm-up for about 2 months, reduced the number of injuries in male and female amateur players between 13 and 25 years, by 30-39%. Studies also showed an improvement in motor and neuromuscular performance such as improved balance, increased quadriceps and muscle strength, speed and agility (7,8,10). The largest reduction in injury risk occurred when players adhered to performing the warm-up correctly. This was achieved with the help of supervision from coaches. Studies where little reduction in injury was seen, could be due to lack of compliance to the intervention and lack of guidance from coaches (7).
These results sound very promising. However, there are some limitations in the studies analysed. These include a risk of outcome bias that could result from the participants knowing that they were receiving the 11+ intervention, and the researcher knowing what group did and did not perform the intervention (9). Some studies also used different injury definitions, with some not even defining the type of injury analysed (8).
Despite these limitations, the warm-up has been successfully utilised in other sporting fields, such as basketball. It has also been endorsed by 20 FIFA Member Associations. Thus, given the high prevalence of soccer injuries sustained by amateur players, the FIFA 11+ intervention is recommended to reduce injury risk (7)(9).

When you’re watching Wimbledon, have you ever wondered how busy the doctors and physiotherapists are behind the scenes?
Well, McCirde et. al. (2016) wanted to determine the rate of injuries that occurred during Wimbledon, which could assist scientists to eventually develop measures to prevent injuries. (3)
They study found that there were 700 injuries over the 10 years of Wimbledon (2003 to 2012), with a total of 12 212 sets played. The overall injury rate was 20.7 injuries per 1000 sets played. (3) McCirde et. al. (2016) observed that males had lower injury rates than females despite males playing more sets. (3) However, Sallis et. al. (2001) found that there was no significant difference in injury rate between females and males across seven different sports including tennis. (6) Differences in injury rates between sexes could be due to woman having higher oestrogen levels, more fat, more flexibility and less muscle mass. (5)
Figure 1 indicates the percentage of each injury type sustained over the 10 years of Wimbledon. This figure shows that there was a large percentage of injuries sustained before Wimbledon, indicating the demanding nature of a professional tennis players’ season. (3)
As seen in Figure 2 and 3, the most common injuries in both genders were in the shoulder, knee and lumbar spine. Groin, hip, heel and ankle injuries were more common in males than females, who suffered more wrist and foot injuries. From this we can see that in both genders, injuries in the lower extremities were most common. (3)
Different tennis court surfaces have different properties. For example, on a grass court the ball bounces less and the rallies are shorter. (3) According to Nigg et. al. (1987) playing on various surfaces could be associated with injuries of the lower extremity. They further stated that overuse injuries have become more prevalent since the increased use of artificial surfaces. More research should be done to investigate the association between tennis court surfaces and injuries. (4)
Research determining injury rates in tennis is extremely limited and often has variable outcomes. It is extremely important to determine injury rates in tennis players as it can improve knowledge regarding player care and can lead to the reduction of injuries. So next time you watch Wimbledon, remember – it’s not all just strawberries and cream!
