The aim of the study was twofold namely (1) to describe and compare the incidence and mechanism of injuries that occurred in the Nelson Mandela Metropolitan University hockey teams that play in the Premier and President Leagues; and (2) to determine the relationships between the level of physical preparation of the relevant players and injury occurrence. The study utilised an exploratory-descriptive epidemiological approach, implementing a cohort study design and was conducted over a period of six months. Data collection was done by means of two physical tests, one to assess the players’ endurance and the other to assess their anaerobic fitness. This was performed twice on the participants during the study. Data collection also utilised four questionnaires to determine the following: the players’ personal information and medical history, the preparation and training the players did for hockey, the incidence and mechanism of the injury the players have incurred and the follow-up of the injury to describe the type of injury and the rehabilitation process. The study included 42 participants with 25 from the two Premier League Teams and 17 from the President League Team. The results were placed into table and graph format and elucidated by means of descriptive statistics. Furthermore inferential statistics and Cohen’s d were utilised to determine both statistical and practical significances of differences between groups mean values respectively. The statistical significance of differences between the frequency distributions of the two sample groups was determined by means of Chi2 tests of independence. Cramér’s V statistic was used when there were statistically significant Chi2 tests results to determine the practical significance of the two sample group’s differences. The variable of highest level of play showed the only significant difference with regards to screening statistics as the Premier League Participants had a higher number of years participating at a provincial level. The injury statistics revealed that the incidence of injury in the Premier League was 4.08 injuries per 1000 athlete-exposures (A-E), while there was a significantly higher incidence for the President League of 14.71 injuries per 1000 A-E. Matches showed a significantly higher incidence of injuries (8.18 injuries per 1000 A-E) than xiv practices (2.42 injuries per 1000 A-E) which follows previous research. Goalkeepers and halves showed the highest occurrence of injuries (36 percent each) and are supported by 59 percent of the injuries occurring on the defensive side of the 23 metre line. Contact injuries (collision 6 percent, hit by stick 17 percent and hit by ball 33 percent) accounted for 56 percent of all the injuries. No significant differences were found between the two leagues with regards to preparation, the Multi Stage Shuttle Run Test (MSSRT) and the Repeated Sprint Test (RST), except for one period each for technical skills and aerobic training. The relationship between injuries and training showed no significances with regards to preparation, MSSRT and RST, although there was minimal balance and proprioceptive training performed. Thus the lower league showed a significantly higher incidence of injury with preparation not being a mechanism for injuries.
