A prospective epidemiologic study of injuries and illnesses in the football matches of the 14th National Student Games of China.

The aim of this study is to determine the incidence and characteristics of football player injuries and illnesses during the 14th National Student Games of China. The results indicate that 32 illnesses were reported, with 17 (53%) involving the gastrointestinal system, primarily caused by environmental factors (24, 69%). The illness incidence rate was 4.3 cases per 100 players or 10.2 cases per 1,000 player-days. Regarding injuries, 122 cases were reported, yielding an overall injury incidence rate was 38.9 per 1,000 game hours, or 1.14 per game. Most injuries resulted from collisions with other players, occurring predominantly 15 minutes before the end of the first half, and 30 minutes before the end of the game. Most of the injuries were in the ankle, thigh, knee joint, and groin. In conclusion, the injury incidence of football players in the 14th National Student Games of China is high, occurring from a variety of mechanisms. Physical contact should be emphasized during training, core strength, and stability training should be enhanced alongside comprehensive injury management and prevention strategies.

Study of the Reliability of Field Test Methods for Physical Fitness in Children Aged 2-3 Years.

Physical fitness measures overall physical health. It is the ability of the body to work effectively and stay healthy during leisure and emergencies. Given the progressive integration of 2-3-year-olds into preschool, physical fitness testing of these children has become increasingly important. We aimed to develop and test the reliability of an appropriate field test method for physical fitness in 2-3-year-olds children. One hundred and three children (44 boys and 59 girls) volunteered for this study. Their height and weight were tested, and the same tester conducted the test twice for handgrip strength, 3 m balance walking, stair climbing, 5 m run, and kicking a ball at one-minute intervals. Pearson correlation coefficient and intraclass correlation coefficient (ICC) were used for reliability testing. The reliability of this field test method for physical fitness was high in the repetitive tests of Chinese 2-3-year-olds for the four items of handgrip strength, 3 m balance walking, stair climbing and 5 m run, and the reliability was moderate for the kicking the ball item. This study indicates that these field-based physical fitness test methods have good reliability and are simple, feasible, safe, and easy to be accepted and understood by 2-3-year-old children; thus, it may be used as a reference for professionals in China and abroad.
