Knowledge about risks related to sustaining a concussion or returning to play too soon varied in both groups. Attitude: 26% of coaching staff and 31% of players reported being very confident or confident in recognizing a suspected concussion. Half of the players (52%) reported to always report symptoms of concussion if feeling any. One (1%) member of the coaching staff and 24 (10%) players reported feeling that a player can return to play with mild symptoms after a concussion. Behaviour: Most coaching staff reported they would have supportive behaviour if faced with a suspected concussion on the pitch.

The introduction of the 50:22 law requires defensive teams to reposition players to anticipate and counter kicks, thereby reducing the number of players in their defensive front line. This study investigated the impact of the 50:22 kicking law on kicking profiles by comparing the 2021 and 2022 seasons, as well as examining the success rate of 50:22 kicks during the 2022 season in South African rugby union tournaments. A retrospective research design was employed, utilising video-based performance analysis software (Nacsport Scout Plus) for data collection. The analysis encompassed all general play kicks from 177 matches spanning two seasons and tournaments, amounting to a total of 6,479 kicks. Within this dataset, there were 53 successful 50:22 kicks out of 162 attempts. Key findings revealed an upswing in kicks by scrum halves (2021: 20%, 2022: 26%; <i>p</i> = 0.00) and a concurrent decline in kicks by fullbacks (2021: 21%, 2022: 18%; <i>p</i> = 0.01).

PAH% (<i>p</i> < 0.001) and body weight (<i>p</i> = 0.014) showed the strongest differences across selection levels, where the bias compared to regional level was 0.23 standard deviations (SD) for PAH% at national level and 0.41 SD at international level, while body weight appeared to be particularly related to international team selection (0.36 SD in bias). Relative age showed a moderate positive correlation with PAH% (<i>r</i> = 0.38), but only trivial correlations with all the other biological and physical variables examined (<i>r</i>=-0.05-0.11).</p><p><strong>Conclusions: </strong>The lack of association between relative age and the estimates of biological maturity timing and the additional physical characteristics suggests that relative age and biological maturity are distinct constructs.
