Pre-race screening and stratification predicts adverse events - a 4-year study in 29585 ultramarathon entrants, SAFER X. The screening before the race and risk tetratization in endurance athletes can predict unwanted events during a race. To determine if screening predicts unwanted events before the race and risk tetrativity during a race. 29585 participants (male 71.1%, average age = 42.1 years; Female 28.9%, average age = 40.2 years) In the ultra-marathon race ‘Two Ocean’s’ (56 km) filled out a medical screening questionnaire before the race and were made before theRace divided into four specified groups as very high risk (existing cardiovascular disease 3.2%), high risk (risk factors for cardiovascular diseases 10.5%), medium risk (existing other chronic disease, medication attraction 53.3%) and low risk(33.0%). Starters, finishers and medical contacts were recorded.The DNS rate (not started) (per 1000 participants not started), the DNF rate (per 1000 starters, not finished), the rate of unwanted events \ [per 1000 starters, which were also started DNF or oneMedical intervention had ] and the rate of medical contacts (per 1000 starter with a medical encounter) were compared by risk categories. Unwanted events were significantly higher at the very high risk (68.9) (per 1000 starter) than at low risk (51.3).The DNA rate differed significantly between the mean risk and low risk (207.4).The DNF rates did not differ in very high risk compared to the low risk (44.2), and the rate of medical contacts did not differ between the risk categories, but the very high risk of significance compared to low risk (6.9).
Medical screening and risk mediation Before a race, athletes can identify with a higher risk of unwanted events.Further studies should be carried out in larger cohorts to clarify the role of medical screenings before the race in reducing unwanted events in runners.
