Tights can be \"tight\", just like trendy and cool slang.
But can compression tights really help you run faster or further?
Some runners say yes, but a recent study published at the annual meeting of the American Academy of Sports Medicine in Denver, Colorado, found that the evidence was thinner than Veron and spandex --Leg clothing.
However, do not run away from tights.
Keep in mind that this latest study was published at a conference and has not yet been published.
Putting forward a study at a science conference is like a successful proposal.
This suggests a commitment, but there may be a lot of things going on between engagement and actually walking down the aisle.
Therefore, the results are considered as preliminary results before a thorough scientific peer review is actually conducted.
Ajit Chaudhari from the Department of Physical Therapy at Ohio State University conducted the study with his colleagues.
Nike offers funding and two sets of prototype compression tights.
Researchers asked 17 experienced male long-distance runners to run on the treadmill for 30 minutes.
The intensity speed of wearing three different sets of clothes: running shorts, low
Compression tights and high
Compression Tights (
Not once, but set different sets in different runs). The results?
According to the measurement of the special reflector, the compression tights do reduce the amount of muscle vibration in the legs.
However, tights do not seem to affect muscle strength or how high runners can jump before and after running.
Here\'s CBS\'s report on the study: there are indeed various limitations to the study before you come to the conclusion.
Thirty minutes is not long, there are not many people in 17 subjects, and there are not many women in 17 men.
Does the effect take more than 30 minutes or once to accumulate?
For people of different sizes, shapes and ages, will compression tights have different effects?
Is the history of running or injury important?
So, what is the theory behind running in tights?
One theory is that less muscle vibration leads to less muscle fatigue.
Think of the leg muscles as a football team.
If some of your team members are busy running or vibrating in random directions (
This will be very worrying)
On the pitch, your team is less likely to achieve their goals, basically goals. Tights (
Again, in theory)
Can reduce vibration and keep all your muscles focused on the task at hand (
Or, rather, feet)
More efficient and longer duration.
Another theory is that tights can help the blood flow in your legs by squeezing your veins so that the blood will return to your heart faster. (
In this case, imagine your leg as a toothpaste tube.
An extra squeeze will move more of what\'s inside your leg. )
A better cycle brings more oxygen to your muscles and removes substances that make your muscles sore and weak, such as lactic acid and liquid build-up.
The third theory is that tights can keep your legs warm and prevent injuries.
This theory uses your legs as a car engine.
A colder engine may turn off more easily.
Also, in theory, tights can make your legs more air powered, especially if you have a lot of leg hair (I mean a lot).
Now that you think of your legs as a very hairy toothpaste tube with a car engine and a football team, what is the scientific evidence behind these theories?
Well, some of these statements don\'t just come out of thin air, like the benefits of having a yellow honeycomb in your vagina.
In fact, compressed clothing is often used as a medical device.
To prevent or reduce swelling in the legs, doctors usually open compression socks.
Patients with blood circulation problems or risk of blood clots often wear this stockings.
Now, medical compression stockings usually look a little different from running tights made of nylon, cotton, spandex or natural rubber.
So you might want to double
Check before you buy medical compression stockings for a run, just like you want to make sure the bra is really a sports bra before you go to the gym.
But these two types of tights work mainly through a similar mechanism: compression.
Nevertheless, the medical use of preventing or treating a disease is not exactly the same as that of a sporting performance.
In support of the claim that tights improve sports performance, science is still in its infancy.
The journal Sports Medicine, published in December 2016, gave a systematic review of existing published scientific research.
Based on this review, scientific research that can be found in major scientific databases, such as one\'s deceased father grind, MEDLINE, SPORTDiscus, and Web of Science, has not shown significant improvements in the following measures: Running
Like half a month. marathons, 15-
Run 5 kilometersand 10-
Km run and 400 m sprint)
Oxygen intake, blood lactic acid concentration, Blood Gas Dynamics, heart function (
Including heart rate, heart discharge volume, heart discharge index, moderate air volume)
Leg strength after running.
However, published research did show a slight improvement in long contractions such as fatigue time, running economy, lactic acid clearance, perceived force, maximum voluntariness, and reaching peak leg muscle strength immediately after running, muscle damage and inflammation were also marked.
In addition, compressed clothing appears to have a moderate effect on the body core temperature and has a significant effect on the later stage
Exercise leg soreness and how long a runner can walk before muscle fatigue.
For example, a study published in the Journal of Strength and regulation studies sought to determine whether wearing compression socks within 48 hours of running a marathon would help recover.
The study allowed 33 runners to complete the treadmill run test two weeks before and two weeks after running the marathon.
Within two days of the marathon, runners wearing compression socks performed better on the treadmill test.
So there is indeed some hope for tights, in addition to keeping your vibrating leg muscles, but in order to make a stronger conclusion, it is necessary to publish more scientific research.
Another question is: How much does compression tights affect your head?
No, I\'m not suggesting you wear these leggings on your head.
Instead, Will wearing a compression tights make you feel better or more sporty?
Psychology is an important part of sports performance.
Just ask the person who \"choked\" or did not perform well in the game.
Feeling better may make you run faster.
In addition, there may be different time and place for compression tights.
In warm weather, compression tights are not necessarily much better than bare
Legs while running (
The point is the word \"leg).
However, when it is too cold outside to be bare (again, bare-legged)
When running, tights can work better than bulky clothes such as trousers.
Bottom line: Take the time to do more scientific research before drawing any strong conclusions about motor performance.
At the same time, so far, bodysuit doesn\'t seem to hurt running performance, according to scientific research, and there may be some benefits.
So if they make you feel better and you can afford them, you don\'t mind putting them on and taking them off, why not put them on?
