In any case, another thing I often observe about runners is the position of their feet
.
Now, considering that you run with your legs instead of your arms, why is this important? In general, it’s because you lose too much blood
.
I don’t like to use the term for many reasons
.
That’s what he’s like now, a little bit of a bounce
.
There is no clear video showing where it happened, however, I suspect it happened here
.
Given that the temperature was around 55 degrees Fahrenheit (13 degrees Celsius) and the weather conditions were good, it looked promising at first
.
Another consideration is a vertical rebound
.
Higher cardiac output can improve performance
.
However, this is where Jim Walmsley really shines
.
The first thing we need to see is his stride frequency
.
To be honest, I would be more surprised if we didn’t see any signs of fatigue
.
It’s going to be more than 60 miles, which should be challenging
.
Until the last 20 kilometers, this is where he finally slowed down to about 18 minutes and 30 seconds every 5 kilometers
.
And a few years ago, he did his running analysis at western state 100
.
This affects your cardiac output, which is very important for endurance exercise
.
I think we should consider other factors that may have a greater impact on his running: one is the bleeding on his shoulder
.
One way people try to quantify this is by looking at the angle of the lower leg relative to the ground, or tibia angle
.
The result was 6 hours, 13 minutes and 33 seconds
.
This happened on January 23 during the carbonx
.
As bleeding occurs, this may cause red blood cell volume to decrease
.
It’s like after this moment, when we see him again, we can see him bleeding
.
He was strong throughout the race and his speed was quite steady, running a little more than 18 minutes every 5km
.
2 project
.
It’s definitely a very tiring task, making people tired both physically and mentally
.
For Jim Walmsley, he had to run at a relatively low intensity
.
But I think it’s interesting to see his final performance, what happens when he’s tired? Now let’s look at a more specific aspect of his running
.
This happens at the end of the game, and I usually edit it in the middle of the game, such as when I analyze him in western state 100
.
Anyway, we can also take a look at the previous video
.
Even so, you can see his determination, he continued to work hard to the end
.
Now that we have some background for this run, let’s take a look at this video, which clearly shows his run
.
This highlights what an incredible runner Jim Walmsley is
.
However, we won’t discuss these special shoes in this video
.
The look of the head is usually a sign of fatigue, as it is here
.
In any case, from the beginning to the end of the race, it’s an incredible race
.
But again, he looks good here, with nothing to do with optimizing performance
.
Throughout the game, his shoulders were bleeding, but Jim Walmsley kept on
.
His goal is to break the world record of 100km set by Nao kazami of Japan, which is 6 hours, 9 minutes and 14 seconds
.
In the end, he was 11 seconds behind the world record
.
First of all, let me introduce the background of this competition: in this video, Jim wangley is running 100km
.
Another reason may be the shoes, which is also a reason to make your own video
.
At about 3 hours and 20 minutes, his shoulder seemed to have been cut by the fence
.
In turn, this may reduce your cardiac output and your overall performance.
.
Although this may be true, the biggest reason may be based on the characteristics of walking speed, which is related to the relative strength of the runner
.
Here he runs 165 steps per minute, similar to the steps he took for hundreds of miles from the western states
.
However, I’m not surprised that he’s running at his pace
.
A common problem is that when a coach or running expert observes a runner, the stride is too long where their feet are too far from the ground, which may lead to low efficiency
.
For an incredibly long race like the 100km, you can’t run at a high-intensity pace, or you won’t get to the end
.
The ideal warming temperature will fluctuate depending on the athlete, however, this is generally considered to be between 45 ° F and 57 ° f (7-14 ° C)
.
If you’re interested in my talk about shoes in relation to running and performance, please let me know and I’ll think about it in another video
.
As you can see, his shins are almost perpendicular to the ground
.
It was set by Japanese athlete Keiyu Shatian on June 21, 1998, and it was also set in the suru super marathon
.
As people often say, the more important thing may not be how the foot touches the ground, but the relationship between its landing position and the body
.
It’s important to remember how hard the game was! In general, when considering the situation of the competition and the players, I think he looks great in the whole competition! If I can’t do that, I won’t look as elegant as he does
.
As I mentioned earlier, we usually observe that the pace or rhythm of a good long-distance runner is around 180
.
Usually, we’ll have our head looking straight ahead, in a more neutral position
.
Now let’s move on to run analysis
.
I don’t think we should give priority to changing his running mechanism
.
Now, there may be other reasons that affect landing, such as terrain and shoes
.
Here, he seems to show more midfoot landing
.
On June 24, 2018, local time in Japan, Nao kazami, a native of Japan, won the 100 kilometer championship in the super marathon race in zolujian Lake in 6 hours, 09 minutes and 14 seconds, and broke the dust laden world record of men’s 100 kilometer race for 20 years
.
One of the reasons people usually think of is that the longer the leg, the less likely it is for him to maintain a certain stride frequency
.
On the contrary, it may be more due to two other things: one is the slower stride frequency, and you usually see more vertical oscillations when you run at a slower stride frequency
.
He runs most of the time on his own, which requires more brain power than some people realize
.
The original world record was also set by Japanese athletes
.
Finally, let’s take a look at the upper body: what’s worth noting here is the head position, you can see his head up
.
But he still has 45 minutes to break, and he broke the American record, which is an amazing achievement
.
Some people tend to attribute this to the dominance of “quadriceps” and “buttocks”
.
Cardiac output is basically how much blood your heart can pump in a minute
.
Now another thing we can look at is the way the foot touches the ground for the first time, which is the most common way the foot touches the ground
.
This time, let’s take a look at Jim wangley, who is going to break the world record of 100 kilometers
.
This landing takes a more balanced approach, because it seems to spread the load on the legs, and the knee and foot areas are more balanced
.
Compared with other foot landing patterns such as hind foot and forefoot
.
In this particular case, Jim Walmsley seems to be in the right position
.
Because the assumption behind this is flawed, but I’ll talk about it next time
.
[running class] tibial angle, a measure of lower limb performance, seems to be a more common feature of elite long-distance runners
.
Notice how I say relative, because 6 minutes per mile is not easy for most people
.
