1. Do you need to wear underwear in wearing compressed pants?

Men are generally entangled in the problem of wearing panties.In fact, many Running compressed pants can not wear underwear.Ordinary underwear is generally made of all cotton, with poor sweat function.And these compressed pants inner pockets are generally used with high -breathable and Smooth materials with high comfort, which can effectively reduce friction in itself. If you wear underwear, to a certain extent, you will be isolated.Lost the original feature.Therefore, compressed pants of professional brands such as SKINS, CW-X, 2xu, can run 5-7km short distance roads without wearing underwear.

Of course, if you run a long distance, you should choose carefully.On the one hand, long -distance Running and long -term Running can easily cause sweating and humidity.On the other hand, sweat stains contain a lot of salt, which can easily cause embarrassment after air drying.It is recommended to choose Sports underwear, many brands also have it, and the breathable sweat -pumping effect is also great.

2. Do you wear shorts outside the compressed pants?

Generally speaking, when it is hot, there is no need to wear shorts, which will affect the effect of Running.

In addition to shame, the larger effect is windproof.It is believed that in an environment above 10 degrees, traditional loose shorts are more than enough. The compressed pants outer and shorts are only needed below 10 degrees. At this time, it is more warm.Don't look at only a few cloths, you can significantly help your core parts in the wind "through difficulty".In addition, there is a small detail that shorts can increase a lot of small pockets more conducive to storage.

3. Do you need to wear underwear in the Compressed jacket?

As for girls, more entanglement is whether to wear underwear.According to data, about 11%of women usually run without underwear, because they think it will restrain their hands and feet.In fact, it is not true that the amount of sweats in exercise and the impact of the body are much higher than the normal state. This influence is positively related to the size of the cup and the impact of exercise.

There are three types of general sports BRA, namely: simple fixing, pressure -type fixed formula, and composite structure.

Among them, the simple fixed type is only fixed with a layer of elastic mesh fabric, and there is basically no design for the human body structure. Most of them coexist with sports vests and suspenders.This kind of fixedness is poor, suitable for girls with low impact movements and small cups.

Pressure fixation is the most widely used bray type. It also mainly depends on the elasticity of fabrics to form pressure on the chest and achieve a fixed purpose.Different from simple fixing, it will fully consider the breast shape, structure, stress on the shoulders, back force, etc. in tailoring, so as to maintain relative comfort while or not fixed.

The third type of composite structure is the most fixed style. In addition to the stress -type fixed structure, there are generally special steel brackets to obtain better support.Good fixation and protection under impact movement.

In order to protect themselves, it is recommended that girls still choose a sports BRA that is most suitable for themselves. They must have both fixed support and sweating and breathability.

Of course, whether or not wearing underwear and underwear must be based on the feelings of runners.

[Source of raincoat] The historical raincoat of raincoat is due to a "mistake" of workers

The raincoat on rainy days, plus its strong wrapping silhouette, plays an important role in shaping the character image. Remember to have a Chekhov's "People Put in the Set" in High school. The character is lonely. Burchov, who is timid and fearful, is "abiding by the law", is that it always takes umbrellas, raings, and Raincoats in the sunny day. Essence

Although the raincoat made of rubber is not permeable, it is hard and crispy. It is neither beautiful nor comfortable to wear on the body. British metallurgist Parker decided to improve this kind of clothes. Use carbonide to do solvents, dissolve rubber, make waterproofing technology, and apply for patent rights, and sell it to a person named Charles, and the raincoat starts to produce a lot.

After entering the 20th century, with the emergence of plastic and various waterproof fabrics, the style and color of Raincoats are becoming more and more fashionable. It has no longer simply used as a functional jacket and has become a fashion item.

In order to strengthen the protection of marine fishery resources and promote the harmonious coexistence of man and nature,The agricultural and Rural Ministry issued the "Announcement on Adjusting the Marine Valua Restaurant Resting System" to further adjust and improve the maritime vile -season fishing system.

The difference between flying flying and gliding umbrella

1. Global umbrella

(1) The gliding umbrella is a full flexible stamping -type wing umbrella. When the umbrella coat is inflated, it forms a shape similar to an airplane wing. The air in front flows from the top and the lower wings to generate lift.It does not need to fly to high altitude with aircraft such as aircraft, only on the higher hillside or traction, and then take off with air flow, and finally land in the designated area.

(2) Global umbrella is a simplified version of high -altitude skydiving. You don't need to use too much manpower and material resources to do it alone, but the gliding umbrella's requirements for the weather are more picky and are a sport of waiting for the wind.

2. Flying on wing

(1) The equipment of this sport in wing flight is mainly composed of wing flight clothes and parachutes. The pilot needs to jump from a certain safe height and use the wing flight uniform to fly.The deceleration and landing to the ground are just a role in the event of a safe buffer and landing. Most of the time, the whole process is used to fly through the wing -mounted flight.

(2) Learn the basic skills of skydiving first, and complete the parachuting license for 25 jumps. Next, more than 200 parachutes will be completed. After completing more than 200 parachute, find a wing flying coach or institution to learn high -altitude wings to learn high -altitude wings.Put a flight.

Is the safety factor of gliding umbrella high?

high.

1. Scropping umbrella is essentially an aviation movement, which cannot be regarded as extreme sports. It is just a part of the limit.

2. The gliding umbrella experience has professional and tight training coaches. A coach takes only one adult experience at a time.

3. The demand for gliding umbrellas is also strict: rain, wind, fog, wrong wind, air control, air control, etc. cannot fly.

4. In Europe, the gliding umbrella project is called "Laolai Le". As young as a few years old, and the old age, you can easily learn the gliding umbrella.

The principle and structure of the gliding umbrella

1. Principles

(1) The gliding umbrella itself does not have any motivation. The reason why it can fly is that except that the umbrella coat is full of special shapes, it is controlled by the pilot, combining air power in the atmosphere.

(2) The speed and lift of the gliding umbrella will generate speed and lift during the air, and its speed and lift are far greater than its resistance.Because in terms of structure, the inner structure of the gliding umbrella coat is equipped with airbags. Before the air is filled with air, the gliding umbrella has no substantial edges. Once the inner airbag is full of air, the edges and corners will appear at the front of the gliding umbrella.

(3) In this way, the appropriate airflow of the gliding umbrella when flying in the air leads the flow from the wings surface, the resistance is parallel to the opponent's wind, and the weight is combined with the air above the wing, so that the glide umbrella can develop speed.

2. Structure

(1) Umbrella wing: The umbrella wing of the gliding umbrella is similar to a willow leaf, which is divided into wings and wings.Between the upper and lower wings, there are dozens of air chamber pillars (wing ribs), and the wingsal ribs divide the upper and lower wings of the gliding umbrella into dozens of gas chambers.When the umbrella wing and the air are relative to the air, the air enters the air chamber from the air inlet. Under the action of the air pressure, a certain pressure is generated in the air chamber to form the umbrella coat and maintain a certain rigidity.Because each gas chamber is intended, the air can be uniformly flowing between the gas chamber to ensure that the pressure inside the umbrella wing is stable.

(2) Umbrella rope: The umbrella rope is used to play a supporting suspension effect. It is a transmission component that connects the connection between the umbrella jacket and the backbone and the manipulation system.The umbrella rope is divided into 3-4 groups (called A, B, C, and D) in the back, and is symmetrically distributed on both sides of the central axis of the umbrella.The upper end of the umbrella rope is usually connected to the wing surface of the umbrella coat with a Y -shaped fork.

(3) The manipulation system: The manipulation system of the gliding umbrella is composed of the manipulation band, the manipulating rope (brake rope) and the Sleeve (manipulation rod).The entire manipulation system is symmetrically distributed on both sides of the center line of the umbrella, and the upper end of the left and right -handed ropes is also Y -shaped, and there are multiple connections to the back edge of the umbrella.The left and right manipulation bands are divided into two front and rear.The upper end of the front control Belt is connected to the A and B umbrella ropes through the fast -moving ring; the upper end of the manipulating Belt also connects to the C and D umbrella rope with the fast -lifting ring.There are also gliding umbrellas that connect the group D rope to the back, and the group C umbrella rope is connected to a transition Belt connected to the front and rear manipulation bands.

(4) Belt system: We are commonly known as a bag in the strap. It is a license component that fix the pilot and connects to the entire umbrella rope system.The strap system is composed of the main bag straps (back straps, chest Bags, belts and leg straps), back pads, seat cushions, and metal ring buckles.Subtiliated umbrella strap systems are common and supine.
