　　The passing criteria for the assessment items are divided by age, and there are seven groups of obstacles in the 400 meter obstacle course. Because we have to pass through obstacles once in both directions, it should be said that Cheng has to pass through 14 obstacles. Cheng is composed of the following seven obstacles: cross pile, trench, low wall, high board jumping platform, single plank bridge, high wall, and low pile net.

　　The passing criteria are: 2 minutes and 30 seconds for those under 25 years old, 2 minutes and 40 seconds for those between 25 and 30 years old, 2 minutes and 50 seconds for those between 30-35 years old, and no assessment for those over 35 years old.

　　The 400 meter obstacle training is a physical fitness training that causes great suffering for many soldiers. In this training, there are a total of 16 various obstacles, and it is generally not easy for people to complete the 400 meter obstacle. Those who have served in the military know that there is a time limit for 400 meter obstacle training, and the qualifying time is two and a half minutes. We know that it takes more than a minute to run 400 meters without obstacles, but how many people can guarantee to complete it in two and a half minutes in front of 16 obstacles? So the 400 meter obstacle is a terrifying presence for many soldiers, and there are also many instructors who use the 400 meter obstacle as one of the corporal punishment projects. Many people are also aware of the five kilometer load off-road, and relatively speaking, most soldiers would choose the five kilometer load off-road rather than the 400 meter obstacle. This shows how terrifying the 400 meter obstacle training is. The 400 meter obstacle is a traditional sports training project in our army. Through training, we can develop comprehensive skills such as running, jumping, climbing, supporting, balancing, and crawling in action, improve physical fitness such as speed, endurance, coordination, and agility, cultivate brave, tenacious, and persevering willpower, and lay a good foundation for overcoming various artificial and natural obstacles during wartime. Now let Brother Bing teach you how to pass the 400 meter obstacle. The 400 meter obstacle is a physical training project that involves 8 sets of obstacles and 16 obstacles in a 400 meter round trip obstacle field. The sequence of passing is: running 100 meters flat - turning - crossing 3 step stakes - jumping over a low wall when crossing a trench - climbing a high board jumping platform - passing through a cloud ladder - passing through a single wooden bridge - climbing over a high wall - crawling through a low pile net - turning (returning) - crossing a low pull net - climbing over a high wall - bypassing a bridge column - passing through a cloud ladder - crossing a high board jumping platform - drilling a hole - jumping down and climbing up a trench - crossing 5 step stakes - turning - reaching the 100 meter endpoint

　　Plum Blossom Pile; Composed of 5 cross piles with a diameter of 0.3 meters and a height of 0.1 meters above the ground. The midpoints of the three cross piles on the right are 2.3 meters apart, 0.3 meters away from the centerline of the runway, and 5 meters away from the end line. The midpoints of the two cross piles on the left are 2.3 meters apart, 0.6 meters away from the centerline of the runway, and 6.15 meters away from the end line. Huai'an 400m Obstacle Standard 400m 100m Obstacle Equipment

　　A low wall; Width of 2 meters, height of 1.1 meters, and thickness of 0.2 meters. The hole is 0.5 meters wide, 0.4 meters high, and its lower edge is 0.6 meters above the ground. It is located on the left side of the low wall.

　　High board; 1.8 meters high, 2 meters long, 0.5 meters wide, and 0.05-0.08 meters thick. The composition and passing order of the manufacturer of training equipment for crossing the sea and landing on the island in Laiwu are as follows:

　　100 meter run → turn around the flag → cross the three-step pile → cross the trench → jump over the low wall → pass through the high board jumping platform → pass through the cloud ladder → pass through the single wooden bridge → climb over the high wall → drill and climb the low pile net → turn around the flag and return → cross the low pile net → climb over the high wall → bypass the standing column under the single wooden bridge → pass through the cloud ladder → pass through the high board jumping platform → drill through the hole → jump down and climb up the trench → cross the five step pile → turn around the flag → run 100 meters to the finish line. The "Physical Exercise Standard Assessment Regulations" stipulate that starting from a 400 meter obstacle can be done in a standing or squatting position, and starting blocks are not allowed. When conducting the 400 meter obstacle assessment for common subjects, the starting method must be a lying down position.

　　The breathing method of the training equipment manufacturer for crossing the sea and landing on the island in Laiwu:

　　At the beginning of running on flat ground, naturally deepen your breathing, and the rhythm of your breathing should be coordinated with the running rhythm. At the end of the run, the frequency and depth of your breathing should increase, and when passing through obstacles, you can use "wide range" force. After passing through obstacles, one should adjust their breathing in a timely manner, focusing on exhaling air. Breathing is done using the nose and half open mouth, and the breathing method is basically the same as that of middle and long-distance running.

　　Notes for manufacturers of training equipment for crossing the sea and landing on the island in Laiwu:

　　1. Climbing over a high wall. The body passes through a high wall.

　　2. Walk around the bridge pillar. The body must go around every pillar.

　　3. By jumping on a high board. The body passes through two tabletops and a high board.

　　4. Drill through the hole. The body passes through the hole.

　　5. Jump down and climb up the trench. Jump off the trench and climb up again.

　　400 meter obstacle equipment manufacturer tells you: the process of making 400 meter obstacle equipment

　　1. The main frame is welded with 12 # channel steel to form an I-shaped base, which is firmly welded and has a standard right angle. On the basis of the I-shaped base, weld channel steel and square tube as columns, and weld four triangular brackets near the column feet as supports to ensure stability and firmness. The middle is made of cedar wood, which has good thickness stability and can prevent a normal adult from tipping over. Huai'an 400m Obstacle Standard 400m 100m Obstacle Equipment

　　2. Paint (spray coating), process: There are two colors: camouflage and military green. The wooden board and main frame are polished to ensure that there are no burrs on the main frame and wooden board, which is not easy to hurt hands. Surface spraying and spraying are carried out.

　　The surfaces of all steel parts of 400m barrier equipment are subject to primary treatment such as pickling, phosphating and sanding, and then the imported electrostatic epoxy based powder is applied for surface treatment. The product has the advantages of acid and alkali resistance, damp heat resistance, aging resistance, and beautiful appearance. It is suitable for wet and acid rain environments, and can be used indoors and outdoors. The product coating formula does not contain toxic elements, so as to avoid damaging the health of users.
