The study of rate and incidence of sport injuries in P.E students:3.5 year longitudinal follow-up study

The purpose of this study was investigated the injury rate (number of injuries/time in 1000) and incidence (number of injuries/number of subjects in 1000) of sports injuries in P.E. students in related to frequency and type of their sport class, competitions and recreational activities of them. In a longitudinal follow-up study 72 P.E. student include male (n=28, age 21.6±2.6) and female (n=43, age 20.26±1.3) during 3.5 year period (7 semesters) were examine. All injuries of the subjects were recorded at the end of each semester. Data of first semester used as a pilot study. Friedman test was used to analyze the data (p<0.05). In total 574 injuries were recorded (285 injury for male and 289 injury for female). Incidence exposure of injuries was 832.1 in sport class, 328.5 in competitions and 612.2 in recreational activities. Also the rate exposure was 282.67 in sport class and 187.5 in recreational sport activities. In a totally lower extremity with 45.4% (3.7±17.4 injury per each subject), upper extremity with 32.2% (2.7±2.6 per each subject), trunk with 12.5% (0.87±1.3 per each subject) and head, face and other segments with 9.9 (0.94±2.7 per each subject) have had most injuries. Importantly, most frequent injuries were showed in gymnastic class for females and in soccer class for males. There is significant difference between number of injuries and various semesters (p<0.05). Although, this difference was significant for upper extremity, lower extremity, head and face injuries but there is nʹt significant difference between trunk injuries and various semesters. It can be concluded that high incidence and the varieties of sport injuries in related to some specific sport classes and risk factors emphasized on modifying of teaching style and planning of educational program of P.E. students.
