How to Run to Avoid Injury
Daniel Lieberman, the barefoot-running evolutionary biologist from Harvard published a study back in 2010. The study was about the collision forces of feet hitting the ground with and without shoes. The study examined the impact while landing on the forefoot or heel.
The new study also observed the role of shoe cushioning and which type of shoes are best for you. The crucial point right from the start is how quickly force is applied when we land on our forefoot or heel. If a lot of force is applied when landing on your heel, you can get easily injured. The recent study shows that it’s not even important how you land on the ground with your heel or forefoot, the force that you are applying is crucial. Additionally, what’s crucial is speed and shoe characteristics.
Also, researchers found that having more cushioning in shoes doesn’t seem to reduce the loading rate for runners. What about running barefoot?
When barefoot, runners would more often land on their forefoot which would soften and prolong the landing. However, if you land on the heel while running barefoot then you are going to generate a high loading rate while putting a lot of stress on your calves.
Peter Weyand from the Southern Methodist University said about running barefoot and landing on your heel:
“There likely are injury implications, and these do line up with the eager barefoot adapters getting Achilles injuries.”
The study does not give us final answers on what running style to use, what type of shoes to buy and how to reduce the risk of getting injured. What we do know is that the force of hitting the ground is essential for a comfortable running experience and avoiding injuries.
Insomnia Tied to Depression
Insomnia is related to stress and overall bad sleeping habits, but it is also closely related to heart diseases, depression, and other psychological disorders.
In the US, insomnia costs us approximately $63 billion each year in lost productivity. It is estimated that a third of the worldwide population suffers from insomnia-related symptoms. Still, insomnia as a disorder is not completely understood, explained and treated. However, insomnia is associated with neuroticism, depression, diabetes, and cardiovascular diseases. It’s important to keep in mind that all the listed conditions are overall linked to sleep patterns and characteristics such as being a morning person or a night owl. Getting enough sleep is crucial for your physical and mental health.
Recently researchers found a strong link between insomnia and genes involved with coronary artery disease and depression. The research confirms that we should take sleep and insomnia as a disease seriously.
Richa Saxena of Massachusetts General Hospital in Boston said:
“Insomnia is an important sleep disorder to be taken seriously, both for its impact on quality of life … and on future depression and heart disease.”
If you are struggling with insomnia, you should visit your doctor and get the help that you deserve.
Hayabusa 2: Asteroid image shows touchdown marks
A beautiful, new image from Japan’s Hayabusa 2 spacecraft showed a dark spot where it touched down on the surface of an asteroid. Researchers are not sure how exactly the spacecraft created the spot although it is evident that the spacecraft had a small impact on the asteroid. Scientists suggest that the spot could be created by grit being blown upwards by the spacecraft or it could be created by the bullet being fired into the ground.
After taking images, the spacecraft then ascended to the position of about 20 km distance from that surface on the asteroid and took images. Previously, Hayabusa 2 dropped a reflective and small target mark on to Ryugu which was used as a guide as the spacecraft descended to the rough surface of the asteroid.
The Japanese space agency planned to carry out the touchdown operation in October last year. However, images showing the surface made it more difficult for scientists to find the perfect location that was flat and large enough to sample. What controllers hoped is to find an area of about 100 meters in diameter to target and land the spacecraft. It was vital for scientists to choose the location where the likelihood of spacecraft hitting a rock would be low.
