In 1983, Joaquim Cruz, the Brazilian middle-distance runner, started his preparation for the Los Angeles Olympic Games, trained by Luiz De Oliveira. In a very nice article published in "Sports Illustrated" on 24 December 1984, Kenny Moore describes the belief of de Oliveira in the effectiveness of breath hold training (now called hypoventilation training in its improved version) and how he used it with Cruz:

 "To defend against oxygen debt, the most dramatic and dizzying is training by holding your breath. When you do 1:14 pace for 600 meters and you have 200 to run, you are going to be in lactic acid distress. This gets you so you don't feel destroyed by it. Cruz holds his breath for distances up to 75 meters in his circuits, and runs 300-meter intervals (in 40 seconds each) without breathing for the last 40 meters".

A few months later Joaquim Cruz won the 800m gold medal in the Los Angeles Olympic Games. You can read the full article here.


The 1st international symposium on altitude training took place on the 7th and 8th of July in Font-Romeu (France). The presentations were of high quality. There was even a little bonus with Samuel Bellenoue (the coach of the AG2R pro cycling team) performing a cycling exercise with hypoventilation on a Wattbike under the supervision of  Xavier Woorons.

2018 is already off to a good start: the study we carried out in collobaration with Lausanne University has just been accepted for publication. It shows incredible performance gains in highly-trained rugby players who trained for 4 weeks using repeated sprint training in hypoxia induced by voluntary hypoventilation (RSH-VHL). You can find the paper here


ARPEH starts a new study to try and investigate the physiological effects of repeated sprint training with voluntary hypoventilation in highly-trained cyclists. The study will take place at the Velodrome de Roubaix. To be followed...

RSH-VHL Roubaix


We are proud to announce the publication of our last study that deals with the acute effects of repeated cycling sprints in hypoxia induced by voluntary hypoventilation (RSH-VHL). The main outcome is that exercising with RSH-VHL induces a fall in muscle oxygenation without impairing performance compared with the same exercise in normal conditions.This method may be worth using in a training programme. You can read the summary of the article here


Discover our new video on Youtube: a rare short document from the 1950's which shows Emil Zátopek, the famous Czech long-distance runner, performing a hypoventilation workout.


Great news for Hypoventilation training: the method has been officially included in the panorama of the methods used to perfom hypoxic/altitude training (presented in the number 1 journal of sports sciences: Sports Medicine)

ARPEH and the University of Lille (Northern France) begin a new scientific study that aims to determine the physiological effects of a repeated sprint exercise performed with voluntary hypoventilation at low lung volume. After showing that this kind of intervention is effective to significantly improve swimmers performance, the time has come to assess the physiolocal causes of such improvement and to assess whether this exercise can be performed in running or cycling.


We are pleased to announce you the creation of the Youtube Channel "Hypoventilation Training". It will allow us first to share visually the news of this training method and its utilization in different kind of sports and second to make you better undersand how it works. You can already watch our first video that was taken at the 2016 European Congress of Sport Science in Vienna, Austria, in which Xavier Woorons presents the results of a study dealing with the effects of hypoventilation training on swimming performance.

Xavier Woorons will participate in the 21st Congress of the European College of Sport Science (ECSS)which will take place in Vienna (Austria) between 6th and 9th of july 2016 to present his research on the effects of hypoventilation training at supramaximal in swimming. Let's meet on the 8th of july from 6:00 PM in the Room S2 to attend the presentation. Here is the general programme.

The article that shows the positive effects of hypoventilation training on swimming performance has just been published in the issue of June of the American Journal Medicine & Science in Sports & Exercise. You can read the paper on the scientific site Researchgate.


The University of Lausanne (Switzerland), in collaboration with ARPEH and the University of Lille (France), publish an original study on the effects of repeated sprint training in hypoxia induced by voluntary hypoventilation in swimming. The results show that this training method is more effective for improving repeated sprint ability in swimmers than the same training performed under normal conditions. This study, published in the International Journal of Sports Physiology & Performance, confirms the results obtained in the previous research conducted in swimming.  Hypoventilation had never been performed at such velocity!


A  study published this month demonstrates once again the positive effect of hypoventilation training, through the combined effect of hypoxia and hypercapnia, in swimmers' performance. The article can be consulted here.


 2016 starts well! ARPEH and the Pluridisciplinary Research Unit 'Sport Health & Society' (URePSSS) of Lille University (France) has just published a study in the American Journal Medicine & Science in Sports & Exercise on the effects of hypoventilation training on swimming performance. For the first time the method was used at high exercise intensities. The results show a marked increase in performance for the 100-, 200- and 400-m freestyle trials. Waiting for the publication of the paper in the journal, you can read the summary by clicking here.


A study carried out by greek researchers and published this month in the "Journal of Human Kinetics" shows that training with hypoventilation over a 4-month period improves time performance in fin swimmers for the 50-m apnea trial and the 400-m surface trial.

We wish you happy new year 2015!

In 2015, a new approach to hypoventilation training will be investigated, in order to make this method even more effective. The first results should be published by the end of the year.


A study has just shown that the hypoxic and hypercapnic effects of hypoventilation training could increase haemoglobin concentration and VO2max by 5% and 10% respectively! These results have not been published in an international scientific journal and remain to be confirmed. They are however encouraging.

An American study that has just been published in the journal "Scandinavian Journal of Medicine and Science in Sports" has showed that several weeks of training including hypoventilation workouts could improve performance in swimming. It's a good news, this is going in the right direction! A summary of the study here.


The website has published an article on hypoventilation training and the researches carried out by ARPEH. We are grateful for their support. You can find their article (in French) by clicking here.


The scientific study dealing with hypoventilation in swimming, which has been carried out by ARPEH and Paris 13 University, has just been published on the internet. For the first time, thanks to an innovative technique allowing the measurement of blood O2 concentrations, we have shown that swimmers could train under hypoxic conditions at sea level if they use hypoventilation at low lung volume. You can get an overview of the paper by clicking here. The paper is due to be published officially in the journal Respiratory Physiology Neurobiology at the beginning of January 2014.


1 month after being created, many of you have already visited We thank the people who have sent support and kind messages.


Birth of the website! We hope many of you will enjoy it and will find it interesting.
