Practical information for ”nordic<br />

walking”<br />

Every of age of patients are <strong>pro</strong>per for<br />

“Nordic walking”. The same - every time is<br />

<strong>pro</strong>per for walking. The distance for walking<br />

is 3 to 5 km per day. Sometimes can be<br />

even 5–8 km. During walking it is necessary<br />

to make the rest. During brakes – it is<br />

advised to make gymnastic with sticks. It is<br />

advised to look the pulses and care before<br />

pain of heart.<br />

Beneficial influences during and<br />

after “nordic walking”<br />

It is beneficial for heart, for lungs,<br />

for blood circulation and for movement<br />

apparatus. Also is beneficial for immunology<br />

and biochemical <strong>pro</strong>cesses in the<br />

organisms. ”Nordic walking is ”especially<br />

beneficial on the beach of the see” and<br />

particularly on the coast of Baltic.<br />

abstract<br />

The article refers to experimentally<br />

gathered values which are necessary for<br />

computation of human body tolerance level<br />

for external load. Content of this article<br />

is submitted as an original research. The<br />

article presents resultant values of acceleration,<br />

impact duration and forces acting<br />

during a blow to the head of a dummy.<br />

Computation of human body tolerance level<br />

is dependent on the overall acceleration of<br />

head after the impact, applied force and<br />

stress. We obtained correlation between<br />

impact velocity of the impactor and duration<br />

of this impact. Further we elicited<br />

relation of the resultant head injury to the<br />

neck stiffness and also restraining factors<br />

(i.e. gloves and caps). Last but not least we<br />

aimed at the correlation between HIC 15 and<br />

injury severity for described sorts of blows.<br />

Both bibliography reviews and experiments<br />

show significant factors for computations of<br />

the tolerance level resulting from external<br />

forces. As the most important factors are<br />

counted not only head acceleration within<br />

a loading phase both also detecting magnitude<br />

of applied force and stress per unit<br />

area. Course of the head acceleration and<br />

applied force are two most significant factors<br />

for prediction of the extreme dynamic<br />

loading of a human body.<br />
