Description

A kind of clothing pressure variable leggings
Technical field
The present invention relates to a kind of clothing pressure variable leggings.
Background technology
People pay attention to self health, note daily daily life, and the people carrying out various motion gets more and more.Thereupon, people are for sports products such as the requirement of sportswear especially performance requirement also corresponding raising, and hold concurrently snugness of fit and sporting functionality become the new demand of people in the sportswear of one.
Product in the market, in the design of panty girdle, emphatically high resiliency or cut out to reach different parts by piecing together of different elastic fabric there is different flexible design.High-elasticity fabric is used at some position, to strengthen the binding force to these position muscle, while a kind of disclosed in patent CN200580030067.9 can temper greater psoas muscle effectively, also can prevent from not needing to apply the scope of load and panty girdle that the wearing feeling that causes declines to greater psoas muscle because high resiliency part is even set to.Also have and utilize the theoretical constraint realized different parts of bandage, a kind of panty girdle disclosed in International Application PCT/JP2004/005325, forms constraint portion by strip fabric, utilizes bandage theoretical to improve locomitivity and effect.
The elastic fabric used in these technology above-mentioned, can not change in motion process.And in our actual motion process, the state of partes corporis humani position all occurring to change, especially arranges the muscle of one of the key factor of our locomitivity.Human body is when moving, and muscle is tightly fettered, and can reduce the vibrations of muscle and the energy loss that causes.But oxygen during human motion in body divides and enters muscle with nutrient by blood, muscle is due to congested and expand.If tightly constraint muscle now simply, then run counter to desire.Therefore, we are it is desirable that a kind of panty girdle can tackling various change in our motion process in time.
Summary of the invention
The object of the present invention is to provide a kind of double snugness of fit and sporting functionality in the clothing pressure variable leggings of one.
Technical solution of the present invention is:
A kind of clothing pressure variable leggings, wear this clothing pressure variable leggings to move, compared with during relative humidity in clothes less than 40%, when interior relative humidity of pledging clothes is in 60% ~ 100% scope, the clothing pressure of this clothing pressure variable leggings reduces 10% ~ 80%, when interior relative humidity of pledging clothes reaches more than 100%, the clothing pressure of this clothing pressure variable leggings reduces 10% ~ 100%.
At the human motion initial stage, muscle is in warm-up phase, as motion panty girdle common on the market, now tightly fetters muscle, effectively can reduce muscle vibrations to reduce unnecessary energy loss, locomitivity is given full play to.And along with the continuous increase of exercise intensity, the oxygen in body divides and enters muscle by blood endlessly with nutrient, muscle is due to congested and expand.Now, then cause muscle too nervous with initially same clothing pressure constraint muscle, the performance of impede motion ability.Clothing pressure variable leggings mentioned in the present invention then solves this contradiction, makes panty girdle become hommization more, and the demand of the reply human body of intelligence, plays locomitivity to greatest extent in time.It is mainly reflected in, and when perspiring, in clothes, (air layer of skin and check room) relative humidity constantly rises, and after panty girdle absorbs gaseous state sweat in clothes or liquid sweat, clothing pressure reduces, and the constraint of panty girdle to muscle is diminished gradually.
Wherein, relative humidity in described clothes, its measurement site is before and after thigh or before and after shank, uses the THT-B3T-80 type Temperature Humidity Sensor of the flourish company of day Benshen and THT-B121 type humiture converter to measure.Described clothing pressure uses the contact of Japanese AMI company to press analyzer to measure, and the gasbag selected is diameter 20mm, simultaneously to before buttocks, thigh, after thigh, before shank and after shank 5 measure.
When not wearing under nature tension-free state, 50% of the body aesthetics of this clothing pressure variable leggings is made up of elastic fabric with upper part.This elastic fabric in 30% ~ 80% elongation range, drying regime time recovery stress be 0.3 ~ 12N, and sucting wet state reduces by 10% ~ 80% with recovery stress under degree of stretching state than drying regime, water suction state reduces by 10% ~ 100% with recovery stress under degree of stretching state than drying regime, and this change is recoverable.When reality is worn, when human motion is perspired, in clothes, (air layer of skin and check room) relative humidity constantly rises, and elongation occurs after running into gaseous state sweat or liquid sweat this elastic fabric makes its recovery stress reduce, and when making to wear, clothing pressure diminishes.Constriction when recovery stress and actual dress is closely related, and recovery stress is less, less to the compressing of human body.
Described recovery stress measures the cupping machine using Japanese Ai Ande company, measures according to the assay method of elongation recovery percentage and residual elongation in JIS JIS L-1096.Assay method is: stretched once by elastic fabric, is stretched to till stress is 20N, reads recovery stress when it is returned to recovery stress when extending reply 80% and 30%.Elastic fabric is divided into three kinds of states: drying regime, sucting wet state and water suction state.So-called drying regime refers to that elastic fabric is positioned over balance in standard environment 20 DEG C × 65%RH to be measured after 24 hours; So-called sucting wet state measures after referring to and balancing 24 hours in environment elastic fabric being positioned over 20 DEG C × 90%RH at once; So-called water suction state measures after referring to and being soaked by elastic fabric 100% at once, and described 100% soaks and specifically refers to that the elastic fabric weight of water suction state is 2 times of the elastic fabric weight of drying regime.
Wearing this clothing pressure variable leggings respiratory quotient of carrying out when exercise intensity is the motion of 3 ~ 12Mets is less than 1.15.Described exercise intensity refers to the degree that physical exercise stimulates Human Physiology, and it is one of method to carry out quantization means with oxygen consumption, and exercise intensity during every kg body weight consumption 1 kilocalorie of energy per hour is 1Mets.
Described respiratory quotient is called for short RQ, in referring to that organism is at one time, and release of carbon dioxide and absorb the ratio of volume or the ratio of molal quantity of oxygen, the i.e. CO that discharges of respiration 2with the O absorbed 2molecular proportion.Their CO separately when sugar, fat, protein oxidation 2generation, O 2consumption is different, and thus the respiratory quotient of three is also different.Respiratory quotient is divided into again protein respiratory quotient and non protein respiratory quotient, and protein respiratory quotient by measuring the urinary nitrogen amount in certain hour, then can calculate the decomposition amount of body internal protein, just can draw O during breaks down proteins according to urinary nitrogen amount 2consumption and CO 2generation, thus, according to the total consumption O recorded 2amount and CO 2generation deducts O during breaks down proteins 2consumption and CO 2generation, just can calculate non protein respiratory quotient, i.e. sugar and fatty respiratory quotient.The fat consumed in motion is more than sugar, and when non protein respiratory quotient business is less, the motion that sporter carries out is called aerobic exercise, is a kind of motion of health.In fact, seldom negligible for the protein amounts be oxidized, the mixing respiratory quotient recorded can be thought non protein respiratory quotient.That is, the breathing quotient measured by us is less, and illustrate that the degree of carrying out aerobic exercise is higher, the motion carried out is more healthy.
When carrying out actual mensuration, the cardio-pulmonary function instrument of German Jaeger company is used to measure oxygen consumption and the carbon dioxide output of sporter, use Japanese メ ト ラ ー human body precision balance to measure the body weight of sporter, thus calculate exercise intensity and respiratory quotient, computational methods are as follows:
The body weight <kg>*3.5<ml/kg min> of exercise intensity=oxygen consumption <ml/min>/(sporter)
Respiratory quotient=oxygen consumption <ml/min>/ carbon dioxide output <ml/min>
Wear this clothing pressure variable leggings carry out exercise intensity be 3 ~ 12Mets move to perspire and perspire be motion to absolute humidity in clothes before quiet time clothes in more than 1.1 times of absolute humidity time, compared with before perspiration, heart rate ascensional range is lower than 10%.The number of times that described heart rate and heart are beated within a certain period of time, embodies the speed of heartbeat in human body certain hour.Same person, the decreased heart rate when quiet or sleep, increased heart rate during motion or time excited.During human motion, heart rate ascensional range is less, then then less to the burden of heart, advantageously in the performance of locomitivity.
Wherein, absolute humidity in described clothes, its measurement site is before and after thigh or before and after shank, uses the THT-B3T-80 type Temperature Humidity Sensor of the flourish company of day Benshen and THT-B121 type humiture converter to measure.Described heart rate uses the U.S. MORTARA12 holter recording box that leads to measure, and adopts 5.0 editions softwares to carry out data analysis.
Wear this clothing pressure variable leggings carry out exercise intensity be 3 ~ 12Mets move to perspire after recover, compared with during motion, during recovery, heart rate variability LF/ (LF+HF) value ascensional range is lower than 20%.
Described heart rate variability and HRV, refer to the situation of change of successively heart beat cycle difference.Although heart autonomic activities is relevant with various pacemaker tissue, heart rate and the rhythm and pace of moving things thereof are by autonomic nerves system and parasympathetic and stomodaeal nervous system co-controlling.Spectrum analysis shows, HRV comprises high frequency (HF) composition and low frequency (LF) composition.HF composition reflection vagal tone, LF composition, by sympathetic nerve and vagus nerve double influence, is wherein preponderated with sympathetic nerve.The mensuration of composition component is composed in LF and HF, can the harmony of evaluate cardiac sympathetic nerve and vagal activity.When human body is in quiet situation, vagal excitation is preponderated, and the change of heart rate is mainly subject to vagus nerve and regulates.And when human body is in the situations such as motion, nervous, pain, sympathetic activation is preponderated.The numerical value of LF/ (LF+HF) formula is larger, embodies sympathetic activation and accounts for leading role, show that human body tensity is larger; On the contrary, the numerical value of LF/ (LF+HF) formula is less, embodies vagal excitation and accounts for leading role, show that human body more loosens.
During recovery with motion time refer to LF/ (LF+HF) comparing of value, motion stop after 10 minutes, human body when seat state than the difference of the LF/ (LF+HF) during motion state.In general, the LF/ (LF+HF) during motion is than large during seat, but due in several minutes after motion, human body can not return to the rest state before motion at once, and numerical value when therefore recovering can be greater than numerical value during motion.Both differences are less, and ascensional range when namely recovering is less, then show that human body recovers faster after movement, human body more loosens and feels comfortably cool.
Heart rate variability LF/ (LF+HF) uses the U.S. MORTARA12 holter recording box that leads to measure, and adopts 5.0 editions softwares to carry out data analysis.
