improve respiratory health with youbreathe

In our lab at London South Bank University we are progressing the youbreathe research and the results are getting more and more interesting and exciting. We are currently costing up a study in cystic fibrosis patients. Cystic fibrosis and other respiratory diseases such as COPD, neurological diseases such as motor neuron disease and multiple sclerosis and some forms of cancer can lead to increased mucus production which patients often have trouble clearing. If not cleared this mucus can move into the smaller airways of the respiratory tree and even to the alveoli where it can impair the functional units of respiration, block the airways and lead to secondary problems.

Because of the oscillatory nature of youbreathe and the frequency range it operates we believe it can be of enormous benefit in promoting the clearance of mucus through altering the viscosity of the mucus, breaking the bond between the mucus and the airways and promoting the cilia to do their job and move the mucus up and out of the respiratory system.

There are other devices out there which can perform this function such as Flutter, Acapella and other laboratory equipment. The advantage of Flutter over some of the other devices is that it can be used in the home which allows greater freedom to the patient and reduced cost to the primary care trust. The feedback we have received about the Flutter is that it works but the user adherence is low.

The following is a link to a chest respiratory physiotherapy site which describes all the basic forms of sputum clearance :

This is where we believe youbreathe has a significant advantage. youbreathe can not only promote mucociliary clearance but can improve respiratory system performance, which can assist those with respiratory problems get active and live as normal a life as possible. This should increase patient adherence lading to long term benefit.

The trials will hopefully be underway soon and I will report on the findings as soon as possible.

Best wishes, stay healthy.

Respiratory Sinus Arrhythmia cont.

Hi again,

This week I would like to show you some results we have been getting in our labs, specifically relating to respiratory sinus arrhythmia (RSA). Remember RSA is the variation in heart rate during inspiration and expiration, and shows the effect of breathing on cardiovascular control. Actually what RSA is showing is the level of parasympathetic control over the cardiovascular system. Sympathetic control should only be active in times of stress such as fight or flight, but because of the way we live our lives and more importantly because of the way we breathe, we can stay in a state of high stress demonstrated by low RSA.

I have been working in the lab with Dr Dave Green from Kings College London and we have been looking into the effects of youbreathe use on the cardiovascular system. If you look at the graphs below, the top one shows a fit guy, but his RSA is low (see there is no regular pattern in the bottom line relative to the top line).

Now compare that to the trace below. This guy is not as fit, but trains regularly with youbreathe, and you can see the high regularity between the two lines.

This is a very important finding and a sign of the long term benefits of youbreathe use on cardiovascular health.

We are continuing with this research which we will publish in due course. Please read my previous posts for a full description of the kinds of physical symptoms we are talking about today.

See you all next time.

Work less, Benefit more.

Recently a “new” training modality is hitting the headlines. Due to its use by celebrities such as Madonna and Kylie Minogue, vibration training is becoming all the rage with outrageous claims being made for the benefits including “45 minutes worth of exercise in 15 minutes…!” Clearly strap lines like this make for great headlines to sell magazines, newspapers and vibration devices, but is it true?

Researchers at London South Bank University have published a paper in a peer-reviewed scientific journal demonstrating that during and subsequent to a single bout of leg extension exercise with vibration at 35% of 1-repetition maximum (1-RM), subjects responded in a similar manner to the responses observed subsequent to the subject performing a single bout of leg extension at 70% 1-RM without vibration. The longer-term training studies are not finished yet but this result suggests that lowering the exercise intensity (weight lifted) and adding a vibration stimulus could lead to similar benefits as high intensity resistance training. It is still very early days for vibration research and application but the important principle appears to be reducing the stimulus quantity and increasing the stimulus quality. For these reasons it’s been always recommend that someone interested in using vibration for training, especially at the elite level, consults qualified strength and conditioning practitioners as part of a training programme, such as the Human Performance Centre at London South Bank University.

The most common method of vibration training is that of vibrating platforms that the user performs exercises on. These devices have been used often in research but the results produced, although offering potential, are not consistent. Some users find that these devices can cause nausea, and if used incorrectly can cause the vibration to be sent straight up the spine to the base of the scull (as this user found out to his cost!). For these reasons we prefer the idea of targeted vibration directly to the exercising muscle ensuring a more specific training stimulus and eliminating any of the unpleasant side effects.

I have recently released a targeted vibration device for the respiratory system called youbreathe which causes the airflow into and out of the lungs to be pulsatile stimulating the stretch reflex of the respiratory muscles. Preliminary results look very exciting with similar acute responses to those seen in the leg training above. youbreathe is currently being used by elite cyclist, tri-athletes, footballers and rugby players who all report perceptible benefits for their sports performance. More trials are under way with future plans to conduct clinical trials with the aim of reducing symptoms of cardio-respiratory disease such as coronary heart disease, asthma and COPD.

In conclusion, vibration training certainly seems to offer the possibility of increasing the return on your exercise investment, getting more response for a given effort. However it would be too soon to draw conclusions about which is the best vibration training method (targeted vs platform) or which protocol is best for a particular desired effect (endurance vs power). I’d like to recommend taking advice from qualified practitioners and incorporating vibration training in a complete training programme. Certainly vibration training seems to offer great potential for rehabilitation in clinical populations and for training the elderly.
