ABSTRACT

BACKGROUND:

The studies of plantar pressure mainly focus on barefoot,while the research regarding the effect of shoes on kinetic parameters is little.

OBJECTIVE:

To explore the peak value of foot plantar pressure between barefoot and wear shoes in max force,max pressure,load rate and impulse during the natural walk,and to search the parameter relationship between barefoot and with shoes.DESIGN,TIME AND

SETTING:

The the same body control analysis was performed at the Laboratory of Sports and Human Science of Nanjing Institute of Physical Education in October 2007

PARTICIPANTS:

A random sampling method was used to selected 10 male college students from the Nanjing Institute of Physical Education which aged(21.00?2.40) years,weighing(71.53?3.16) kg,body height(176.32?2.62) cm,and foot length(25.67?0.92) cm.According to the regulation,informed consent was obtained from each participant.

METHODS:

Normal gait of 10 participants were measured by Foot scan7.0 plantar pressure test system,including barefoot and with shoes.MAIN OUTCOME

MEASURES:

The distribution of maximum force,maximum pressure,load rate and impulse.The parameter relationship between barefoot and with shoes were assessed in the study.

RESULTS:

The max force existed in the area of heel medial,the second metatarsal and the third metatarsal.The minimum force existed in the area of the toes 2-5 and the fifth metatarsal.The max pressure of barefoot existed in the area of the toes 2-5 and the second metatarsal and heel during walking.The load rate of heel was the highest.The max impulse existed in the second metatarsal and the third metatarsal and heel.The minimum impulse existed in the toes 2-5 and the fifth metatarsal.When wearing shoes,the max force existed in the area of the mid foot and toe1,The minimum force existed in the area of the toe 5,during walking the max pressure existed in the area of the instep.The load rate of the mid foot and heel was the highest.The max impulse existed in the mid foot.The minimum impulse existed in the fifth metatarsal.

CONCLUSION:

The parameters of forefoot,instep,and heel were larger than barefoot during walking,especially those of the phalanges2-5 and instep.
