6 exercises to boost leg muscles

Introduction 

1. Squats

2. Lunges

3. Deadlifts

4. Step-Ups

5. Calf Raises

6. Glute Bridges

Here are 6 effective exercises to strengthen and boost your leg muscles. These target the major muscle groups in your legs, including the quads, hamstrings, glutes, and calves.


<p>Researchers on Monday (September 9) announced that they have created the first robotic leg which has "artificial muscles" that help them jump across a range of surfaces.&nbsp;</p>

<p>These "artificial muscles" are oil-filled bags which will help machines move like humans.</p>

<p>In a video, the small and disembodied robot leg was seen hopping over grass and rock along with a new study in&nbsp;Nature Communications.</p>

<p>To everyone's surprise, this muscle-powered robotic leg can carry out complex movements like adapting and jumping on&nbsp;uneven terrain.</p>

<h2><strong>Humanoid robots to carry out 'boring labour' in houses?</strong></h2>

<p>Speaking to AFP, study co-author Robert Katzschmann said that the researchers can use this technology&nbsp;in future for making humanoid robots which can help out with "boring labour" around the house.</p>

<p>“If we combine the robotic leg in a quadruped robot or a humanoid robot with two legs, maybe one day, when it is battery-powered, we can deploy it as a rescue robot,” said&nbsp;Katzschmann, one of the lead developers from ETH Zurich.&nbsp;</p>

<p>The robotics professor at Switzerland's ETH Zurich University further explained that conventional&nbsp;humanoid robots have been built using motors and rigid metal joints which are similar to those that have been used on factory construction lines.&nbsp;</p>

<h2><strong>Is it safe to bring such muscle robots into houses?</strong></h2>

<p>Apart from being very expensive, these muscle-built robots can prove to be dangerous if they get entry into the houses of people.</p>

<p>If one were to "fall on you, it is going to be quite painful", said Katzschmann.</p>

<p>He added that a future robot helper needs to not only carry heavy things but "also give someone a hug or shake hands".</p>

<p>The study's co-author Thomas Buchner explained that “as soon as we apply a voltage to the electrodes, they are attracted to each other due to static electricity. Similarly, when I rub a balloon against my head, my hair sticks to the balloon due to the same static electricity.”&nbsp;</p>

<p>When such robots are paired on a skeleton, these actuators mimic the “paired muscle movements of living creatures” by creating one muscle's contraction one muscle while extending the other.</p>

<p>The scientists explained that the musculoskeletal system is “elastic” because of which they can flexibly adapt to the terrain.</p>

<p>“It’s no different with living creatures. If we can’t bend our knees, for example, walking on an uneven surface becomes much more difficult. Just think of taking a step down from the pavement onto the road,” Katzschmann said.</p>

<p>“On the infrared image, it’s easy to see that the motorized leg consumes much more energy if, say, it has to hold a bent position,” Buchner further said in the&nbsp;press release.</p>

THIS robot has muscles. Here's how it is different from humans

<p>What’s the reason&nbsp;behind&nbsp;some people like Olympian sprinter Usain Bolt running&nbsp;extremely fast while others not even coming close to them?&nbsp;Yes, genetics&nbsp;do&nbsp;play a crucial role&nbsp;but&nbsp;it’s not like you have no control over your endurance and&nbsp;that you&nbsp;can’t train your mind to improve.</p>

<h2><strong>The muscle game</strong></h2>

<p>First of all, let’s understand how our muscles that are responsible for the movement of our body work, including running and walking.</p>

<p>There are mainly two types of muscles involved in these exercises: Fast twitch and slow twitch.</p>

<p>The human body has over 600 moving muscles that help us do work and walk. Different muscle types have a different mix of fibres.&nbsp;Muscles that are fast twitch—gastrocnemius—are used for sprinting and jumping, whereas slow twitch&nbsp;are used&nbsp;for walking and jogging.</p>

<p>Fast twitch muscles move&nbsp;quickly,&nbsp;and&nbsp;generate greater force but require a lot of energy. So, these muscles tire quickly and help us fast for short distances.</p>

<p>Those who run fast are able to use these muscles better, and more efficiently. Fast twitch muscles are predominantly not decided by genes, so you always are in control of what you can achieve through better training.</p>

<p>On the other hand, slow twitch muscles help you run at a slower speed but with greater endurance. Marathon&nbsp;runners&nbsp;as well as&nbsp;cyclists&nbsp;tend to have strong slow twitch muscles.</p>

<p>These muscles are&nbsp;mostly&nbsp;determined by your genes, but you can still train yourself to improve these muscles too.</p>

<h2><strong>Role of brain</strong></h2>

<p>You can improve both types of muscles using your brain.&nbsp;At the end of the day,&nbsp;your brain controls the movement—how long your stride is, how your arms move, how your feet hit the ground and even the techniques you use to breathe.</p>

<p>You can align your brain with the best running technique. Proper posture is essential, ensuring your body stands tall. An economical stride, where your feet land below you rather than too far out in front, can prevent deceleration.</p>

<p>Engaging your whole body by having your arms pump in opposition to your legs, running on your toes, and maximising the time spent in the flight phase with both feet off the&nbsp;ground,&nbsp;can improve your form. Proper running techniques allow your muscles to create more force and work together,&nbsp;ultimately&nbsp;increasing your speed.</p>

The muscle game: How people like Usain Bolt are able to run so fast

Here, we bring you the news that is trending across WION's social media platforms- In the back and forth struggle to survive on the air, one of the most important features a war plane can have is a reduced radar cross-section or stealth in the world where detection is a matter of life and death.

<p>Adequate sleep plays a crucial role in maintaining basic health processes, especially during teenage and young adult development. A recent study has highlighted&nbsp;the link between poor sleep and muscle dysmorphia, a concerning trend among youth.</p>

<p>Published in the journal Sleep Health, the study involved over 900 adolescents and young adults. Participants with more muscle dysmorphia symptoms reported getting fewer hours of sleep and experiencing difficulties falling or staying asleep over a two-week period.</p>

<p>Lead author Kyle T Ganson, PhD, MSW, stressed on&nbsp;the negative impact of poor sleep on mental health among adolescents and young adults, particularly those with muscle dysmorphia symptoms. Poor sleep may worsen functional and social impairment, increase suicidal thoughts, and exacerbate negative mental health symptoms.</p>

<p>"Poor sleep among those who experience muscle dysmorphia symptoms is concerning as it may exacerbate the functional and social impairment these individuals commonly report, as well as increase suicidal thoughts and behaviours," he said.</p>

<p>Previous studies indicate that adolescents and young adults often sleep less than the recommended 7 to 10 hours per night. Additionally, poor sleep is associated with mental health disorders such as anxiety, depression, and psychosis.</p>

<h2><strong>Exploring the relationship</strong></h2>

<p>Ganson's study is the first to investigate the connection between sleep and muscle dysmorphia. The authors suggest that various factors may contribute to this relationship, including body image dissatisfaction, obsessive thinking, anxiety, and displacement of sleep due to physical activity.</p>

Young adults’ sleep woes linked to muscle dysmorphia, study finds

<p>In recent years, the world has been witnessing several cold wars. Be it between the US and Russia, the US and China or other big powers, there have been several conflicts brewing in the world lately. &nbsp;</p>

<p>Every other world power seems to be flexing their muscles more than ever to exert influence. China is threatening Taiwan, Russia has already launched invasion of Ukraine, North Korea has been firing up missiles to scare the US, Japan and South Korea, etc. &nbsp;</p>

<p>Most of the conflicts seem to arise from the flexing of muscles and can be easily solved with discussions and talks. But is anybody ready to listen? &nbsp;&nbsp;</p>

<p>To safeguard or counteract, the world has come up with different alliances, like NATO, Quad, Aukus, etc. The million-dollar question is that is it resolving the issue or just fueling hatred or misconceptions? &nbsp;</p>

<p>Russian invasion of Ukraine is one of the best examples to show how the flexing of muscles can result in war. In the time to come, the world may witness more wars as there have been efforts to fuel anger and not reduce animosity among nations. &nbsp;&nbsp;</p>
