Team illness prevention strategy (TIPS) is associated with a 59% reduction in acute illness during the Super Rugby tournament: a control-intervention study over 7 seasons involving 126 850 player days.

OBJECTIVES: To determine whether a team illness prevention strategy (TIPS) would reduce the incidence of acute illness during the Super Rugby tournament. METHODS: We studied 1340 male professional rugby union player seasons from six South African teams that participated in the Super Rugby tournament (2010-2016). Medical staff recorded all illnesses daily (126 850 player days) in a 3-year control (C: 2010-2012; 47 553 player days) and a 4-year intervention (I: 2013-2016; 79 297 player days) period. A five-element TIPS was implemented in the I period, following agreement by consensus. Incidence rate (IR: per 1000 player days; 95% CI) of all acute illnesses, illness by main organ system, infectious illness and illness burden (days lost due to illness per 1000 player days) were compared between C and I period. RESULTS: The IR of acute illness was significantly lower in the I (5.5: 4.7 to 6.4) versus the C period (13.2: 9.7 to 18.0) (p<0.001). The IR of respiratory (C=8.6: 6.3 to 11.7; I=3.8: 3.3 to 4.3) (p<0.0001), digestive (C=2.5: 1.8 to 3.6; I=1.1: 0.8 to 1.4) (p<0.001), skin and subcutaneous tissue illness (C=0.7: 0.4 to 1.4; I=0.3: 0.2 to 0.5) (p=0.0238), all infections (C=8.4: 5.9 to 11.9; I=4.3: 3.7 to 4.9) (p<0.001) and illness burden (C=9.2: 6.8 to 12.5; I=5.7: 4.1 to 7.8) (p=0.0314) were significantly lower in the I versus the C period. CONCLUSION: A TIPS during the Super Rugby tournament was associated with a lower incidence of all acute illnesses (59%), infectious illness (49%) and illness burden (39%). Our findings may have important clinical implications for other travelling team sport settings.

Match injury incidence during the Super Rugby tournament is high: a prospective cohort study over five seasons involving 93 641 player-hours.

OBJECTIVES: To determine the incidence and nature of injuries in the Super Rugby tournament over a 5-year period. METHODS: 482 male professional rugby union players from six South African teams participating in the Super Rugby tournament were studied (1020 player-seasons). Medical staff of participating teams (2012-2016 tournaments) recorded all time loss injuries (total injuries and match injuries) and exposure hours (93 641 total playing hours; 8032 match hours). Injury incidence, injured player proportion, severity (time lost), anatomical location, tissue type and activity/phase during which injury occurred are reported. RESULTS: The overall incidence of match injuries (per 1000 player-hours; 95% CI) for each year was as follows: 2012 (83.3; 69.4-99.2); 2013 (115.1; 98.7-133.5); 2014 (95.9; 80.8-113.1), 2015 (112.3; 96.6-129.9) and 2016 (93.2; 79.9-107.9). The injured player proportion for each year was as follows: 2012 (54.6%); 2013 (49.4%); 2014 (52.0%); 2015 (50.0%); and 2016 (39.8%). The thigh, knee, head/face and shoulder/clavicle are the most frequently injured locations, and muscle/tendon and joint/ligament injuries account for the majority of injuries. Most injuries (79%) occur in contact situations, in particular during a tackle (54%). CONCLUSION: The incidence of match injuries and the injured player proportion in South African teams competing in the Super Rugby tournament is high. Match injury incidence is consistently higher than previously reported for senior male rugby players at elite/professional level. Targeted risk management strategies are therefore needed in the Super Rugby tournament to manage risk of injury.

More than 50% of players sustained a time-loss injury (>1†day of lost training or playing time) during the 2012 Super Rugby Union Tournament: a prospective cohort study of 17,340 player-hours.

BACKGROUND: Professional Rugby Union is a contact sport with a high risk of injury. OBJECTIVE: To document the incidence and nature of time-loss injuries during the 2012 Super Rugby tournament. DESIGN: Prospective cohort study. SETTING: 2012 Super Rugby tournament (Australia, New Zealand, South Africa). PARTICIPANTS: 152 players from 5 South African teams. METHODS: Team physicians collected daily injury data through a secure, web-based electronic platform. Data included size of the squad, type of day, main player position, training or match injury, hours of play (training and matches), time of the match injury, mechanism of injury, main anatomical location of the injury, specific anatomical structure of the injury, the type of injury, the severity of the injury (days lost). RESULTS: The proportion (%) of players sustaining a time-loss injury during the tournament was 55%, and 25% of all players sustained >1 injury. The overall incidence rate (IR/1000 player-hours) of injuries was 9.2. The IR for matches (83.3) was significantly higher than for training (2.1) and the IR was similar for forwards and backs. Muscle/tendon (50%) and joint/ligament (32.7%) injuries accounted for >80% of injuries. Most injuries occurred in the lower (48.1%) and upper limb (25.6%). 42% of all injuries were moderate (27.5%) or severe (14.8%), and tackling (26.3%) and being tackled (23.1%) were the most common mechanisms of injury. The IR of injuries was unrelated to playing at home compared with away (locations ≥6 h time difference). CONCLUSIONS: 55% of all players were injured during the 4-month Super Rugby tournament (1.67 injuries/match). Most injuries occurred in the lower (knee, thigh) or upper limb (shoulder, clavicle). 42% of injuries were severe enough for players to not play for >1 week.

Elite athletes travelling to international destinations >5 time zone differences from their home country have a 2-3-fold increased risk of illness.

BACKGROUND: Illness accounts for a significant proportion of consultations with a team physician travelling with elite athletes. OBJECTIVE: To determine if international travel increases the incidence of illness in rugby union players participating in a 16-week tournament. SETTING: 2010 Super 14 Rugby Union tournament. PARTICIPANTS: 259 elite rugby players from eight teams were followed daily over the 16-week competition period (22 676 player-days). ASSESSMENT: Team physicians completed a logbook detailing the daily squad size and illness in any player (system affected, final diagnosis, type and onset of symptoms, training/match days lost and suspected cause) with 100% compliance. Time periods during the tournament were divided as follows: located and playing in the home country before travelling (baseline), located and playing abroad in countries >5 h time zone difference (travel) and located back in the home country following international travel (return). MAIN OUTCOME MEASUREMENT: Incidence of illness (illness per 1000 player-days) during baseline, travel and return. RESULTS: The overall incidence of illness in the cohort was 20.7 (95% CI 18.5 to 23.1). For all teams, the incidence of illness according to location and travelling was significantly higher in the time period following international travel (32.6; 95% CI 19.6 to 53.5) compared with the baseline (15.4; 95% CI 8.7 to 27.0) or after returning to their home country (10.6; 95% CI 6.1 to 18.2). CONCLUSIONS: There is a higher incidence of illness in athletes following international travel to a foreign country that is >5 h time difference and this returns to baseline on return to the home country.

Illness during the 2010 Super 14 Rugby Union tournament - a prospective study involving 22 676 player days.

BACKGROUND: Illness accounts for a significant proportion of consultations with a team physician travelling with elite athletes. OBJECTIVE: To determine the incidence, type, cause and consequences of illness in Rugby Union players participating in a 16-week tournament. SETTING: 8 teams participating in the 2010 Super 14 Rugby tournament Participants A cohort of 259 elite rugby players from eight teams was recruited. ASSESSMENT: All players were followed daily over the 16-week competition period (22 676 player days). Each day, team physicians completed an illness log with 100% compliance. Information included the daily squad size and illness details including system affected, final diagnosis, type and onset of symptoms, training/match days lost and suspected cause. MAIN OUTCOME MEASUREMENT: Incidence of illness (illness per 1000 player days). RESULTS: The incidence of illness in the cohort was 20.7/1000 player days (95% CI 18.5 to 23.1) with the highest incidence of illness in the respiratory system (6.4: 95% CI 5.5 to 7.3), gastrointestinal system (5.6: 95% CI 4.9 to 6.6) and the skin and subcutaneous tissue (4.6; 95% CI 4.0 to 5.4). Infections accounted for 54.5% of all illness and 26.1% of illness resulted in time loss of ≥1 day. In over 50% of illnesses, symptoms were present for ≥1 day before being reported to the team physician. CONCLUSION: Infective illness involving the respiratory tract and gastrointestinal tract together with dermatological illness was common in elite rugby players participating in this international tournament. A delay in reporting of symptoms >24 h could have important clinical implications in player medical care.
