All the biomechanic studies indicate that the human leg normally bends in walking, to permit hip action and ankle flexion mobility. However, the straightening  leg designers special can also be cultivated, and has been, for the prupose of moving and carrying things on the head  in the vertical mode. But that  means the straight-ening leg is directly underneath, i.e. aligned with the center of gravity.

But given the tendency of homo sap's mind to find ways that do not work,  in this instance most likely the english upper class, occupying India and  Africa, got it into  their heads to develop a new form of walking for sport.. It is a hybrid-not the real African gait, nor Indian gait, but a new pattern.

and, some very few can do it fairly well. Most cannot.

I myself tried, and for a while it worked, but biomechanics caught up with me.

In the July race, I felt good, and was able to move even faster, but then paid the price of  but then two days later my knee and leg gave me trouble.

an X-ray of an already compromised knee -worsened by one of those now recognized a snear useless and 'quack' surgeries: meniscus arthroscopy [sharon Begley, NEWSWEEK], plus a follow up with  a digital analysis of my walking gairt, made it  clear that trying to do classic 'race walk' form would be further damaging.

so I shifted my walk form, and obatianed better ankle mmobility, along wiht hip, and immediately improved, and...won a $50 prize in the September 11th Hubbardston race(walkers division) ..

so, my competitive walking continues, and my race walking discontinued for reasons of biomechnaical conflict and unsustainability..

"if one is not getting better with age and practice  one is getting worse.."  there is no other alternative...

Re: Article on Racewalking
 
 
Tom once told me that a 12 minute mile (5mph) is where race walking and
running are equally efficient.
Apparently according to the study referenced, at a 12 mm pace, race walking
is still less efficient than running. And of course my personnel experience
is that the new straight leg rule is conducive to hip injury.
Note that the race walker pictured does not have a straight leg.

Change your walking style, change your mood

October 15th, 2014 in Psychology & Psychiatry

Our mood can affect how we walk—slump-shouldered if we're sad, bouncing along if we're happy. Now researchers have shown it works the other way too—making people imitate a happy or sad way of walking actually affects their mood.

Subjects who were prompted to walk in a more depressed style, with less arm movement and their shoulders rolled forward, experienced worse moods than those who were induced to walk in a happier style, according to the study published in the Journal of Behavior Therapy and Experimental Psychiatry.

CIFAR Senior Fellow Nikolaus Troje (Queen's University), a co-author on the paper, has shown in past research that depressed people move very differently than happy people.

"It is not surprising that our mood, the way we feel, affects how we walk, but we want to see whether the way we move also affects how we feel," Troje says.

He and his colleagues showed subjects a list of positive and negative words, such as "pretty," "afraid" and "anxious" and then asked them to walk on a treadmill while they measured their gait and posture. A screen showed the subjects a gauge that moved left or right depending on whether their walking style was more depressed or happier. But the subjects didn't know what the gauge was measuring. Researchers told some subjects to try and move the gauge left, while others were told to move it right.

"They would learn very quickly to walk the way we wanted them to walk," Troje says.

Afterward, the subjects had to write down as many words as they could remember from the earlier list of positive and negative words. Those who had been walking in a depressed style remembered many more negative words. The difference in recall suggests that the depressed walking style actually created a more depressed mood.

The study builds on our understanding of how mood can affect memory. Clinically depressed patients are known to remember negative events, particularly those about themselves, much more than positive life events, Troje says. And remembering the bad makes them feel even worse.

"If you can break that self-perpetuating cycle, you might have a strong therapeutic tool to work with depressive patients."

The study also contributes to the questions asked in CIFAR's Neural Computation & Adaptive Perception program, which aims to unlock the mystery of how our brains convert sensory stimuli into information and to recreate human-style learning in computers.

"As social animals we spend so much time watching other people, and we are experts at retrieving information about other people from all sorts of different sources," Troje says. Those sources include facial expression, posture and body movement. Developing a better understanding of the biological algorithms in our brains that process stimuli—including information from our own movements—can help researchers develop better artificial intelligence, while learning more about ourselves in the process.
