- Description: Neuromuscular control during high risk sporting movements, such as abrupt landings found in netball, is viewed as a risk factor contributing to Anterior Cruciate Ligament (ACL) injury. Although the mechanism of injury remains relatively unclear, it has been found that intervention studies have reduced the risk of ACL injury. However, there are limited studies that investigate the neuromuscular contribution to the success of a program. Therefore the purpose of this investigation was to compare neuromuscular characteristics for a balance training group (BT) and landing training group (LT). Twenty-four female netball players from three teams (age 22 ± 5 years) had EMG data recorded for the right lower limb (rectus femoris, medial and lateral hamstrings, gluteus medius) pre and post a 6-week intervention period. Each team was randomly assigned the BT, LT or control group. Subjects performed the intervention program three times per week. The repetitions and complexity of balance or landing tasks during the training period increased each week with a concurrent reduction in feedback regarding torso, hip and knee positioning.

- Description: Introduction: Published netball data have indicated that the ankle and knee are common sites for injury, often as a result of incorrect landing technique. Promising results have been demonstrated across various sports using training intervention studies designed to reduce lower limb injury rates. This qualitative study examines the barriers and facilitators towards the implementation of a 6-week landing intervention program (“Down to Earth”) by coaches of junior netball teams. Methodology: Coaches of junior teams (n = 30) were recruited prior to the competition season (October 2007 to March 2008) and attended a workshop where the coaching requirements of the program were demonstrated. Coaches were instructed to implement the program at training, noting any issues regarding program compliance. Pre- and post-season surveys modelled on the Theory of Planned Behaviour were used to indicate coaches’ attitudes, perceived social norms and behavioural control towards safe landing programs in netball. Retention of correct landing principles was assessed and barriers and facilitators for broader implementation among junior netball coaches were determined. Results and discussion: Results will be presented to indicate how coaches’ attitudes and knowledge towards landing intervention programs can assist in the development of an effective implementation strategy of a training injury prevention intervention, to a broader netball community. An example of feedback provided was”…we have noticed quite an improvement in the kids, and their landing and balancing, so it is all been worth while. We were also discussing…about including the program into our junior training next year and how best to do this”.

- Description: Introduction: In Australia, the National League competition (Commonwealth BankTrophy (CBT)) provided an opportunity to gain an understanding of injuries sustained at the elite level. The purpose of this review therefore is to examine the injury incidence in the CBT competition (2003–2005) and considerations for future injury prevention strategies. Methods: All players in the CBT competition are included in the injury data surveillance scheme. Each team physiotherapist is responsible for assessing, treating and recording injuries within the team. An injury is defined as any netball related physical damage that caused the athlete to miss or modify one or more training sessions, matches or both, and/or required a consultation with a health professional. Results and discussion: The exposure to risk has been estimated from the data supplied for CBT games only to be 71.4, 61.8 and 66.7 injuries per 1000 participations for 2003–2005 respectively. Game injuries account for the majority of injuries with the ankle remaining the most common site of injury across the 3-year period, despite the fact that the majority of players wear ankle tape. The knee was the second highest recorded site of injury for 2004 (14.9%) and 2005 (14%). The majority of injuries are new injuries with three most common mechanisms of injury being collision with a player, landing and overuse injury. Ongoing injury prevention strategies are warranted to reduce injuries resulting from a non-contact mechanism. In addition, training exposure is required to accurately assess the overall risk of injury in netball.

- Description: Introduction: Neuromuscular control during high-risk sports tasks is viewed as a primary risk factor in ACL injury. Attention has also been given to the role of the hip as a possible explanation contributing to ACL injury rates. Typically neuromuscular predictors of ACL injury have arisen from lab-based assessments; however it is possible that this approach excludes important components of actual game-play that may contribute directly to injury risk. The current study therefore, examined muscle recruitment patterns (MRP) during game-play and lab-based conditions that included hip musculature, to consider strategies for lower limb control. Methods: Nine female subjects had EMG data recorded continuously during a netball game. At a subsequent session, in the lab, EMG data was also recorded for three landing conditions. Bilateral EMG was collected via telemetry for rectus femoris, biceps femoris, medial hamstring and gluteus medius. Muscle onset relative to initial contact and the subsequent pattern/s of onset for each land, for each subject, were examined. Results and discussion: Results indicate that the average number of MRP across subjects was 3.6 and 5.8 for the game-play and the lab-based conditions, respectively. When muscles crossing the knee joint were examined only, results revealed that the average number of MRP across subjects was 2.1 and 2.4 for the game-play and the lab-based conditions, respectively. Differences exist when comparing game-play and lab-based measures and the role of the hip musculature in affecting lower limb control warrants ongoing investigation in relation to ACL injury risk.

- Description: The significant cost of injury rehabilitation to the individual and the community combined with the funding provided for injury prevention (IP) research over the past decade demands some measurement of the effectiveness of IP programs. The measurement of IP strategies is a complex issue because injury prevention relies on the behaviours of the sports people involved. This study involved qualitative analyses of interviews conducted with ten netball players and seven football players. The players were selected from the highest and lowest senior grades of a semi-rural community level club. Data collected from the interviews were transcribed and analysed using themes to categorise the information. The findings highlight the different structural issues faced by community level netball and Australian Rules football players. Players who had been exposed to higher levels of competition appeared to have an increased use of and better attitude towards the use of IP measures. Some of the contrasts highlighted were the structure, access and availability of IP measures to players. Netball players did not have access to sports trainers or protective equipment and the choice to use IP strategies was a more personal choice. In contrast, the football clubs had sports trainers and protective equipment was offered to players at no cost. The most significant theme emerging from the study related to the social influences at the community level. The players’ attitudes and beliefs were directly attributable to the acceptance and promotion of IP strategies by significant people within the clubs.

- Description: The aim of this study was to investigate insurance records for a one-year period to determine the injury frequencies and costs associated with different age groups in netball. The insurance records for all netball claims made during 1999 in Victoria were obtained from the insurer and entered into a database. The overall injury rate was 9.49 injuries per 1000 players, with 829 claims for injuries filed with the insurance company. Of all injuries claimed for, 85.3% were to the lower limb, 8.7% to the upper limb, 3.1% to the spine/torso and 2.9% to the head and face. Lower limb injuries accounted for 85.4% of costs, upper limb injuries 10.7% and head/neck/torso injuries 3.9% of total injury costs. Knee injuries accounted for 56.9% of total costs, with ankle and calf/Achilles injuries costing 12.7 and 11.8% of total costs, respectively. Injury prevention strategies should therefore be directed to three main injuries taking into account costs and incidence. These injuries were: ankle sprains, knee ligament sprains and Achilles tendon strains. Specifically, the prevention program for Achilles injuries should be directed to the >25 years age groups. © 2006 Sports Medicine Australia.
