Children bear the weight of schoolbags existing research results show that the primary school pupil carry a heavy weight on their normal growth will adversely affect their growth, development and health effects , has aroused the concern of all sectors of society . In this paper, biomechanics research tools and methods , the application of international advanced plantar pressure measurement system , 30 children in natural walking , shoulders endorsement package ( 2.5 kg , 5 kg ) plantar pressure distribution during exercise . Aimed at when walking by the subjects in three forms and process , plantar peak pressure , impulse , flip the situation inside and outside the foot , foot shaft angle indicators on children's weight-bearing walking characteristics of plantar pressure and gait analysis explore weight-bearing walking gait and normal gait movement characteristics , and thus provide a basis for children 's gait and a children's shoe design data reference. Studies have shown that : 1 subjects in natural walking weight 2.5kg , 5kg weight-bearing support and the support Share gait cycle were higher than the percentage of subjects of natural walking , and increases as the load increases ; swing phase becomes shorter with increasing weight-bearing . Support of the forefoot contact phase with the increase in weight-bearing and growth , to increase the instability of the children walking . With increasing weight-bearing walking foot metatarsal , first metatarsal pressure at the value gradually increases, while the forefoot red suffered accounted for the percentage of the entire foot with the weight increase and increase children's weight-bearing walking foot hands of parts prone to fatigue and injury . 3 foot pedal from the ground phase exists with the with load larger increase in the degree of pronation law , exist with the increased weight-bearing foot shaft angle larger law . 4 should be avoided premature larger weight for children , shoes R \u0026 D personnel design should pay attention to children 's shoes dispersed enough before the hands of the Ministry of the impact of pressure .
