When I posted an article on “crotch shift” on this blog before, it is becoming popular article.
When thinking this again, I think that it is also proof that there are really many people who are suffering from crotch gap.
Especially when starting a marathon or jogging to promote diet and health, there seems to be more people suffering due to the pain of crotch shift.
This is a serious problem.
MID wants to work on this crotch gap problem from the front.
I will think about a solution about crotch shift in marathon and jogging this time.
Anyway reduce friction coefficient
Regarding the cause and type of crotch shift, as described in the above article, the inner side of the thigh rubs with each exercise that the thigh is running due to being thick, causing the skin to become inflamed.
So, in order to prevent this, it is important to “reduce friction coefficient” anyway.
To fundamentally solve the problem is to eliminate the friction of the thigh, that is to thin the thigh to the extent that the thigh does not rub.
However, it is impossible for you to lose the weight that you can only lose weight as it is written in the diet article so far, and about the phenomenon occurring in exercise to do for a diet, “what should I do to thin the thigh” It will not.
It may be possible to physically thin it with a strong tightening spats, but doing exercises in a tightly tightened state to a level not rubbing may have a bad circulation of blood and it also involves danger I can not recommend it.
There are two practical solutions
As a realistic solution, “to improve the slippage between the thighs to lower the friction coefficient” is not it?
There are two methods as follows.
- Exercise by painting petrolatum, skin protection cream etc.
If the thigh itself is made slippery with petroleum jelly or the like, the friction coefficient decreases and it is difficult to cause crotch displacement.
Because there are many people who have similar troubles, special creams are also sold at sports goods stores and net shops. It’s ok if you paint inside the thigh before exercise.Inside, there is a “skin protection cream protect S1” cream that creates a protective film on the skin.
A cream that comprehensively prevents skin troubles caused by friction between the skin and skin, clothes, shoes, and tools.Tribological prevention effect proved at Tohoku University which goes to the top level in Japanese tribology studies (tripology) research!
Skin Protection Cream Protect S1 (tax excluded 1,350 yen) It can be used about 120 times! - Make the inside touching the skin gentle material, rubbing make the outside slippery material
Although I say that the thighs rub against each other, there are clothes in the meantime.
You can reduce crotch shift by selecting this material.First of all, it would be nice to make skin-contacting surfaces skin friendly.
Specifically, cotton is recommended. If you wear boxer pants made of cotton etc, we will protect the skin kindly.And since friction occurs directly on the outside, it is good to have slippery chemical fibers such as nylon and polyurethane.
Many exercise spats are made of such materials in many cases. It is recommended to type that closely adheres to the body to some extent.
Switch to exercise difficult to cause crotch deviation
As an extra edition, there is also a method called “Switch to exercise difficult to cause crotch deviation”. It is a change of ideas.
Specifically, swimming is recommended. Aerobic and anaerobic exercise can be efficiently incorporated by whole body exercise. I do not care about my weight in the water, and the burden on the knees and waist is also less.
The problem is that it will become difficult to get to the pool by all means. For a diet where continuation is important, this is quite a big factor. Personally I hope swimming will go for a change in degree.
Summary
Countermeasure against crotch shift that various methods are considered.
We will also introduce here as new items arrive to MID in the future.
