The Analysis Of Youth Men Basketball Athlete’s Foot Pressure And The Characteristics Of Gait

Objective: The analysis of the plantar pressure and the characteristics of gait for youth men basketball players without sport injury. The analysis of the plantar pressure and the characteristics of gait for youth men basketball players with sport injury.Relative analysis of the players with and without sport injury. The plantar pressure and the characteristics of gait affect sport injury of players.Method: The experimental subject is youth men basketball players. We choose 30 students who above 18 years old and above 5 sport age, study in class 2010 to 2013 of sports training major of the Northeast Normal University by stratified cluster sampling method. The normal group choose 17 students who above 18 years old and not study in sports college. The analysis of gait by three-dimensional gait analysis system. The analysis of plantar pressure by Footscan7 USB. Grouping as if he is a athlete and if athletes are damaged.Results:1. There is big difference between special athlete of basketball and normal people. The stride and step speed of the athlete are greater then normal, but support phase percentage and the move range of sagittal surface of ankle are less then normal.2. There is big difference between special athlete of basketball who without sport injury and normal people. The cycle time, stride, step speed, stride/height and step speed/height of the athlete are greater then normal, but support phase percentage is less then normal.3. The characteristics of gait is same between the athletes who with sport injury and without sport injury, but support phase percentage is less then who without sport injury.4. There is big difference of plantar pressure between special athlete of basketball and normal people. The pressure peak value of metatarsus is average. There is big difference of pressure of No.2, No.4, No.5 and heel medial between athlete and normal people.5. The division characteristics of plantar pressure of special athlete of basketball is the Meta 2 is most. The Heel Medial is more then the Heel Lateral. The Meta 1 is less then heel, and decreases from Toe 1, Meta 3,Midfoot, Meta 4,Meta 5 and Toe 2-5. The plantar pressure is same to normal people, but there are different between Meta 1,Meta 3, Midfoot and Heel Medial, and total pressure is let up.6. There is different of plantar pressure between special athlete of basketball who with and without sport injury. There are different in Meta 3 and Toe 2-5. The pressure is decrease in Meta 1 and Meta 2, build-up in Meta 4 and Meta 5. The plantar pressure peak is in Meta 4. On the whole, athlete’s who with sport injury the plantar pressure peak of Heel Medial is decrease, the plantar pressure peak of Heel Lateral is increase and the center of gravity offshores trajectory.7. The early of support of special athlete of basketball is less time then normal. It is different of start time of Meta 2-5.8. The off time and impulse percent are same between special athlete of basketball and normal.Conclusion:In conclusion, youth men basketball players are the people who easy to sport injury, and the incidence rate is high related to exercise age. There is big difference between special athlete of basketball and normal people. And the characteristics of gait is same between the athletes who with sport injury and without sport injury. There is big difference of plantar pressure between special athlete of basketball and normal people. And there is different of plantar pressure between special athlete of basketball who with and without sport injury. The early of support of special athlete of basketball is less time then normal, and it is same between the athletes who with sport injury and without sport injury. There is larger dependency between toe-out foot and sport injury, so it can be a reference index in choose athletes.
