abstract = {Head acceleration at the time of tackling was measured for forty-seven high school rugby players. The time to reach the peak values for the lateral non-tackle side and tackle side peaks after coming into contact with the tackle machine, as well as the gap between the two peaks (amplitude time) were analyzed. In comparing student grade, the amplitude time of a right Power Foot Tackle of third grade students was significantly shorter than that of first grade students. Regarding differences between left and right tackles, the amplitude time of a right Diving Tackle was significantly shorter than the left side tackle. Differences in the timing of head movements were thought to have been determined by the skill level and shoulder effectiveness of the tackles. Topics for the future study include measurement of head acceleration in a state approximating that of actual motion, point of contact, verification of training, etc. ABSTRACT FROM AUTHOR},

The aim of this study was to compare the last two years academic performances of secondary school rugby players suffering very mild (vMTBI), and mild traumatic brain injuries (MTBI) with sedentary control group. A cohort of 35 secondary school male rugby players (divided into a sub-concussive (vMTBI) group (group 1) (n=26) and a concussive (MTBI) group (group 2) (n=9) at the end of a secondary school rugby season and ten (n=10) participants that were not involved in contact sport (control group 3), were used. The academic results of the participants in the subjects Afrikaans, English, Mathematics and Sciences were obtained from the secondary school records. Group 1 (vMTBI group) and group 2 (MTBI group) showed a statistically significant (p⩽0.05) decrease in academic performance in Afrikaans when compared between year 1 and year 2, (group 1},
