Impacts of Instability Training on the Physical Fitness of Soccer Students

Abstract

Introduction: Most coordination studies are conducted in stable environments, unable to realistically simulate an environment integral to the sports field. The concept of instability training applies the principles of sports physiology, combining real situations from the soccer game to improve students’ sporting ability, and has gained attention from coaches, although it still lacks scientific evidence. Objective: Study the concept of instability training by evaluating its optimization and development effects on soccer students’ motor coordination. Methods: Fifty college soccer students were selected. The students were randomly divided into experimental and control groups, without relevant statistical differences. The experiment lasted one hour daily, three times a week, for six weeks. The control group remained with the usual training while the experimental group had the instability training protocol added. Balance test results were collected with frontal and posterior lower limb support and comprehensive posterolateral scores. Changes in activity performance were also analyzed with the results collected before and after the intervention. Results: The score of the experimental group without support was increased from 101.14 ± 8.22 to 108.73 ± 8.54, higher than the control group (103.8 ± 58.11). The comprehensive score of the experimental group was from 88.85 ± 6.10 to 99.85+8.87, also higher than the control group (88.15 ± 6.43). Conclusion: The effects of instability training to optimize and develop motor coordination in soccer students proved to be superior to usual training, and its introduction into daily training is indicated for more effective promotion of students’ fitness level. Level of evidence II; Therapeutic studies: investigation of treatment outcomes.
