Abstract

Background: In soccer performance, coordination training is important and there is a high chance of injury due to improper concentration during a performance, but there is little research on the relationship with injury. The aim of this study was to assess the effect of dual-task training on young soccer players' attention distribution ability, physical function and performance, and occurrence of injury.
Methods: The subjects were 70 soccer players as intervention group and 52 players were as control group (age of all subjects was 15.9 ± 0.8 years, the height was 168.8 ± 5.3 cm, and the body weight was 59.5 ± 6.2 kg). Agility t-test and an original dual-task agility t-test were measured as indicator of attention distribution ability. The history of subjects’ injuries was interviewed, and a single-leg triple hop for the distance test and a single-leg standing test with closed eyes were measured as physical function. The dual-task training concluded 5 items and the intervention was performed in approximately 20 minutes one time and six times over 3 weeks at a frequency of twice weekly. The number of people with injuries in each group and each measurement value was compared in each group.
Results: The control group comprised 10 subjects with injuries before intervention and 7 after intervention, whereas the intervention group comprised 12 subjects with injuries before intervention and 3 after intervention. No significant differences were observed in any of the parameters after the intervention in either of the two groups.
Conclusion: Whether this difference was caused by the intervention remains unclear; however, it is possible that the training program in this study was effective for short-term injury prevention. The contents of evaluation and training menu should be reexamined in the future.
