kybun ETH study

To investigate the influence of the 'kyBoot' and 'Joya' shoes designed by Karl Müller Sr and Jr on gait when walking and running, and on the forces affecting the feet, the Biomechanics Institute at ETH Zurich (the Swiss Federal Institute of Technology) carried out a study including gait analysis. The study involved 12 test subjects (barefoot, kyBoot, Joya, MBT and 3 test subjects with Joyssy), high-speed videos of the heel strike, kinetic measurements of the ground reaction force and kinematic measurements of the body position and movement.

Summary of conclusions: 

1. kyBoot/Joya trigger greater movement. This is a predictable result, as the soft, supple design of the sole makes it extremely yielding. When we walk barefoot on an uneven, natural surface (in sand, uphill, downhill, etc.) the angles of movement are naturally greater, of course. With the soft, supple design it can be assumed that more effort is required, more energy is used and the muscles get more exercise.

2. With Karl Müller (kyBoot) shoes the movement curves are generally smoother (less jerky).

3. In the initial heel-strike phase the force acting on the body is considerably lower (by a factor of 2–5) than during barefoot walking/running due to the shock-absorbing properties of the Karl Müller shoe soles.

4. No differences were established between the Karl Müller shoes and those with rounded soles regarding upper body posture.

Exercise even keeps your mind in shape!

“Sports are necessary for mental agility. If you want to know how fit your brain is, feel your leg muscles." Johannes Holler, neuroscientist

Even Aristotle knew that exercise has a positive effect on thinking ability. The Greek philosopher liked to lecture his students while taking a walk with them. For more than 2,000 years this teaching method was considered an idiosyncratic oddity, but today studies show that there is a link between exercise and mental ability.

The sports scientist Prof. Wildor Hollmann investigated that link. Hollmann carried out an experiment with two groups of students. During the test they heard nonsense syllables such as “mo, fro, tra”: they had to remember them and repeat them afterwards. The only difference was that the second group was tested while pedalling on exercise bikes. The students in the first group were not able to repeat most of the syllables. The other group of students achieved better results. Hollmann concluded that what we learn is absorbed more efficiently and retained longer in the brain when it is learned along with exercise. Hollmann believes this is because the brain is better provided with oxygen and nutrients during exercise.

Even on a leisurely stroll there is evidence that 20 per cent more blood is fed to the brain. Increased exercise also leads to the formation of new neurons and boosts the production of neurotransmitters. Various kinds of physical activity have been proven to influence our mental potential: whether you go for a walk or take part in a demanding sport, both spark positive changes in the brain.

Improvement in performance through running

A study involving young adults who completed a 30-minute running workout three times a week over a period of six weeks was conducted at the ZNL Transfer Center for Neuroscience and Learning (University Hospital Ulm, Germany). The results showed an improvement in state of mind as well as improved visual-spatial and verbal memory.

Prolonged sitting is dangerous to health

 

A recent study shows link between prolonged sitting and increased mortality.

The research team from the "Pennington Biomedical Research Center" proves in its study that prolonged sitting is very negative impact on health. The long-term study with more than 17,000 study participants shows that sitting increases the risk of dying from cardiovascular disease and other diseases. This connection could even be found among the physically active subjects. This observation is important because it shows that long hours of passive sitting cannot be compensated with occasional exercise.

Moderate exercise is therefore an extremely important factor for a healthy life in today's society.

Sitting less could extend your life

Sitting less could lead to a longer life, a new study says.

Do you sit at work? If most people spent less than three hours a day sitting, it would add two years to the average life expectancy in this country.

Don’t Just Sit There: Stand Up and Move More, More Often

Sitting Time and All-Cause Mortality Risk in 222 497 Australian Adults

Prolonged sitting is considered detrimental to health, but evidence regarding the independent relationship of total sitting time with all-cause mortality is limited. This study aimed to determine the independent relationship of sitting time with all-cause mortality.

The study comes to an interesting conclusion: Prolonged sitting is a risk factor for all cause mortality, independent of physical activity. Public health programs should focus on reducing sitting time in addition to increasing physical activity levels.

The Truth About Sitting Down

As we enter the second decade of the 21st century, there is one thing nearly all modern people in the west have in common: we sit all the time.

 

Though our great shift towards computer-based work has done great things for productivity, it has, unfortunately, done terrible things for our health. From increased risk of heart disease and obesity in the long term, to sharply hampered cholesterol maintenance in the short term, the negative health effects of sitting are starting to weigh heavily against the benefits. Even the medical field – the greatest advocates and reducing sitting time – is plagued by this new health issue. Though doctors and nurses get plenty of walking time, it usually falls to the secretaries, billers, and coders to do all the sitting. And, as we can see, something has to change.

 Click to see: sitting is killing you!

 

Stand up for your health

Marc Hamilton, professor of biomedical sciences at the University of Missouri in Columbia, found in his studies that moderate- to vigorous-intensity physical activity has a key preventive role in cardiovascular disease, obesity, type 2 diabetes, and some cancers.

Whereas standing up engages muscles and promotes the distribution of lipase, which prompts the body to process fat and cholesterol, independent of the amount of time spent exercising. Hamilton’s conclusion and advice: “Just avoid the chair as much as you can.”

kyBounder more effective than conventional therapy mats

In February 2009 a team led by Dr Thomas Bochdanksy, head of the department of Physical Medicine and Rehabilitation at the regional hospital in Feldkirch, Austria, studied the effect of the kyBounder on 31 test subjects, compared with a conventional therapy mat.

He tested the instability caused by the mats based on the distance from subjects’ center of balance. The results showed that exercise on the kyBounder stimulates postural stability far more than on a conventional therapy mat. Dr Bochdansky believes that this intensive way of improving your balance boosts the functions of the deep muscles and, among other things, helps reduce pain, especially in the lumbar vertebrae.

How the kyBounder compares: huge demands placed on your balance system

The data show that greater control is needed to stand still on the kyBounder (= harder work). This is due to the high degree of instability which characterizes the kyBounder, and can be seen on all frequency levels (see graph). According to Bochdansky this result indicates that exercising on the kyBounder makes demands on all the main control systems (visual, vestibular and somatosensory).The expert’s positive interpretation of the study results is that as the kyBounder allows the exercise intensity to be increased, this also improves its effect.

 

What does instability mean for your body?

Your body reacts very sensitively to instability, as in everyday life it indicates a high risk of a fall. Confronted with an unstable surface, your body thus automatically tries to regain stability. In therapy, instability can be used in a highly targeted manner as a stimulus to exercise the body’s natural stabilization mechanisms. This improves your dynamic spine stabilization (= postural stability, core stability), which is a key factor in the occurrence of backache over long distances.

What benefit does instability have during sports or in therapy and rehabilitation?

The trunk is the basis for any movement in your extremities. Generally, it can be said that the stronger that basis is, the better (more precise, targeted, extreme) the movement is. Exercising on a kyBounder leads to a general improvement in your balance and can thus help reduce your risk of a fall. The kyBounder can play a valuable part in every field of preventive work (primary, secondary and tertiary prevention). Moreover, instability can also play a major role in improving your dynamic control of your joints, leading in the case of degenerative illnesses to better kinematics and kinetics and thus ideally distributing the load on your joints.

“When measuring balance we found that the kyBounder provided the most instability compared with other exercise mats. From this we can conclude that balance training on the kyBounder can have a greater effect on dynamically stabilizing the spine, and should thus have a high primary and secondary effect in preventing backache.” Dr. Thomas Bochdanksy, head of the department of Physical Medicine and Rehabilitation at the regional hospital in Feldkirch, Austria.

This instability is also provided by the kyBoot, meaning that the kyBoot should also provide effective exercise with its special walk-on-air sole.

Stand up in your office

Medical research has been building up for a while now, suggesting constant sitting is harming our health - potentially causing cardiovascular problems or vulnerability to diabetes. We can't simply fix it by heading for the gym.
