Abstract:

BACKGROUND: Former studies indicate that some anatomic regions of feet can not only support the most of the human body weight, but also balance the human body. Massive information concerning the physiology, structure and function of foot, lower limb, and even the whole body can be gained by measuring the peak pressure and distribution of these regions.
OBJECTIVE: To observe the dynamic plantar pressure distribution of naturally walking healthy adolescent soccer players, such as peak power values of both feet, loading impulse.
METHODS: The dynamic plantar pressure of 16 to 19 years old adolescent soccer players were tested using the F-Scan Gait three-dimensional dynamic plantar pressure analysis system.
RESULTS AND CONCLUSION：Plantar stress-time curves showed a clear double-peak type. The mean peak force value of the 10 tested plantar region all reached maximum in the lateral heel (P < 0.01). For the ones preferred right foot, the mean peak force value of great toe, the first and second metatarsals, the inner and outer heel regions of the right foot was larger than that of the left foot (P < 0.05). While the mean peak value of the fifth metatarsal, two foot arch regions of the left foot was larger than that of the right foot (P < 0.05). During walking, the load centers in the whole foot contact phase and the outside-ground phase were the first and second metatarsals, the inner and outer heel regions. The maximum load parts of foot were the first and second metatarsals, the inner and outer heel regions. The distribution regularity of left foot was similar to that of the right foot, and there was no difference between genders. In conclusion, there is a consistency in the distribution regularities of the left and right foot static and dynamic plantar pressure analysis in the healthy adolescent soccer players.
