“…Anticipatory worry and fear of uncertainty (high HA1 and HA2 scores) were also noted in the controls. These avoidant behavioural traits imply a tendency to avoid dangerous playing techniques which may result in reduced concussion susceptibility 41. In seniors, however, the inverse relationship was observed with carefree and confident behaviour (low HA) in the controls.…”

BackgroundConcussion occurs when biomechanical forces transmitted to the head result in neurological deficits. Personality may affect the balance between safe and dangerous play potentially influencing concussion risk. Dopamine receptor D2 (DRD2) and dopamine receptor D4 (DRD4) genetic polymorphisms were previously associated with personality traits.ObjectivesThis case–control genetic association study investigated the associations of (1)DRD2andDRD4genotypes with concussion susceptibility and personality, (2) personality with concussion susceptibility and (3) the statistical model of genotype, personality and concussion susceptibility.MethodsIn total, 138 non-concussed controls and 163 previously concussed cases were recruited from high school (n=135, junior), club and professional rugby teams (n=166, senior). Participants were genotyped forDRD2rs12364283 (A>G),DRD2rs1076560 (C>A) andDRD4rs1800955 (T>C) genetic variants. Statistical analyses including structural equation modelling were performed using the R environment and STATA.ResultsThe rs1800955 CC genotype (p=0.014) and inferredDRD2(rs12364283–rs1076560)–DRD4(rs1800955) A–C–C allele combination (p=0.019) were associated with decreased concussion susceptibility in juniors. The rs1800955 TT and CT genotypes were associated with low reward dependence in juniors (p<0.001) and seniors (p=0.010), respectively. High harm avoidance was associated with decreased concussion susceptibility in juniors (p=0.009) and increased susceptibility in seniors (p=0.001). The model showed that a genetic variant was associated with personality while personality was associated with concussion susceptibility.ConclusionThese findings highlight the linear relationship between genetics, personality and concussion susceptibility. Identifying a genetic profile of ‘high risk’ behaviour, together with the development of personalised behavioural training, can potentially reduce concussion risk.

“…27,28 In addition to these general skills, position-specific skills such as scrumming and jumping in the lineouts are also needed. 29 Furthermore, tactical proficiency, which includes visual scanning, pattern recognition, anticipatory skills, situation knowledge, adaptability and decision making on attack and defence, are all required of the developed rugby player.…”

Growing interest in producing expert performance, and increasing sport participation, has led to a number of models being proposed for optimal sporting development. Using physical or psychological developmental milestones as guidelines, these models in sport were aimed primarily at identifying key stages during childhood and adolescence, and to optimise training adaptation for the child to reach his/her full sporting potential. Taking into consideration the long-term developmental models, and the requirements to succeed in rugby, this review aims to prescribe the trainability of junior rugby players using a scientifically evidence-based long-term player development approach. As there have been several recent and comprehensive reviews of the literature on trainability during childhood and adolescence, the aim of this paper is to resynthesise the material and apply it to rugby. Although athlete developmental models suggest that the appropriate application of training stimulus during specific periods in childhood and adolescence will influence athletic potential, recent available literature contends that this concept is inconclusive and requires further investigation. S Afr J SM INVITED REVIEWIn the past, coaches and sport practitioners applied adult-based forms of training to children. However, with the increase in knowledge and understanding of human development, applying adult-based training to youth was quickly questioned. This concern, together with the growing interest in producing expert performance and increasing sport participation, has led to a number of models being proposed for optimal sporting development. Using physical or psychological developmental milestones as guidelines, these models in sport were aimed primarily at identifying key stages during childhood and adolescence, and to optimise training adaptation for the child to reach his/her full sporting potential. In recent times, with the advancement of the understanding of human performance and training, these developmental stages for sport have received some review.

“…19,24 A technically skillful contact technique is considered an asset in reducing the risk of injury and concussion in rugby. 11,29 Therefore, risk-taking behaviours at the elite level may not be associated with the same level of injury risk as the amateur level due to a higher level of skill and execution. Furthermore, Bandura et al (1997) suggests that increased perception of risk is linked to lower self-efficacy and heightened belief of failure, which may increase the risk of an adverse outcome or injury.…”

This study identified a novel association between HA and concussion in rugby players, adding evidence to the role of personality in a multifactorial risk-model of concussion. The findings suggest that lower HA may lead to increased dangerous play in youth rugby, influencing concussion susceptibility. Contrasting associations in the professional cohort suggest further research is required to understand the role of personality in concussion.
