Older People Walking Speed And Fast Walking Characteristics Biomechanical Analysis

walking is an important part of the activity of daily life, especially to oldpeople, With the growth of the age, old people drop to some extent in the functionsof various fields, including of gait. Because there is relatively little researchin gait of different velocity, So this text carries on preliminary research inthis respect, to compare normal steps the biomechanics indexes of characteristicwith walk fast rapidly of the older. 1At Beijing Inst. of Physical Education dependents' district and the old peoplesof residential block amount to upper ground the oldest peoples as the researchobject this text, Use Qualisys shoot and go on and shoot systematically and passsport biomechanics and statistical analysis by infrared light, Draw followingconclusions: Walk while being fast. Walk and lead to the fact relatively heavyground assault and shake, joint in old people,and brain nerve exert an bad influencebackbone fast. When walking fast, the ones of old people relatively unstable attitude, walkand have security, Namely walk and increase the degree of difficulty to a stepof attitudes steadily soon, often walk and do exercises fast, Have certainadvantages to control the stability of a step of attitudes in improving old people.Pay attention to leg speed who old person walk fast control in certain range andpay attention to the coordination of the movement, So as to avoid falling downor other damaging natures accidents. Steps attitudes level and smooth index, Trucksappear two pieces similar wave form of perpendicular acceleration - the time curve,The amplitude of the acceleration and angular speed is indexes which reflects astep of attitudes stabilities of old people the arrow form of truck, Have beenverified further in this experiment.
