Reflections on the Italian conference on track and field

I am on the plane back to London returning from Italy after having spoken at a conference organised by the Italian Track and Field Federation’s regional committee of Veneto and the regional branch of the Italian Olympic Committee. I spent interesting 2 days in Abano Terme for a variety of reasons, some of which I will write about here. I also had time to reflect about my career so far and where I started.
First of all, I have to say it is always a pleasure to get back to Italy. I left many years ago to study and further my education (my first “escape” was in 1996 [time goes fast!]). After the USA, Spain, Hungary and bits and bobs around the World, I arrived in the UK in 2001 (yes it is now 10 years) to pursue a career in sports science. First in academia and since 2005 with the British Olympic Association. When I left Italy, It was with a bitter taste, many things happened which helped me decide to “throw in the towel” and move on.
The main issues were: the lack of meritocracy, the lack of vision and thinking big, the lack of jobs and clear career paths, the inability to work in partnership and the constant bad influence on politics in every field. However bitterness was then transformed in pleasantness by the realisation that leaving Italy was not an exile like some Italians think, but in reality a great opportunity to be thankful for. In fact, since arriving in the UK, I have been blessed with continuous opportunities. I have met some fantastic people, I have had the opportunity to work and collaborate with World Class colleagues in many fields in academia and sport and I have the privilege to work towards the London Olympics for the biggest sporting event which will happen in my country of adoption at least for my generation.
Reflecting on the last 18 years since I started this journey, I realised how much I have learnt and and how much I have evolved as a professional thanks not only to my own hard work and sacrifice, but also thanks to the countless interactions I have had and still have with various people in many fields and thanks to the opportunities I have been presented with.
The conference was also an emotional moment. It was primarily organised to discuss athletics in Italy and around the World thanks to contributors coming from Germany and France. But the main aim of the conference was to remember the immense contribution from the greatest Sports Scientist Italy ever had (in my view): Professor Carmelo Bosco. Prof. Bosco was my PhD supervisor, and I enjoyed some years of hard work on the road with him not only working on various research projects but also working on applied projects with athletes and higher education.

Working with a genius is never easy. It takes effort, it is difficult, it is stressful and requires long hours of “deep” practice and a strong character as well as the willingness to accept criticism and work hard to learn. I feel so lucky of having been working with people like him, Atko Viru, Jozsef Tihanyi (to name a few), because these guys not only were great at what they did (and Josefz still is), but they were passionate about their jobs and were/are totally driven to learn more every day.

Italy was a difficult place to work at the time. The faculty of Sports Science did not have a library. If you wanted to read scientific literature, you needed to book access to the School of Sport of CONI and you were allowed few hours only few days per month. So if you wanted to have knowledge you had to go and get it and it was not easy to do so (mind you there were no queues…so clearly few people were interested in reading!). Unlike now, knowledge is “on tap” [but so is crap], and there is really no excuse for not trying to learn something new every day. For the young readers, this was the pre-PDF era when you had to go to the library, find the journal, take notes or make photocopies. It was a time when a literature search required a week to be done. You needed to hand in at reception a floppy disk with a list of keywords and come back a week later to receive the files with the literature search outputs. We had an office to do literature search with 1 computer. There were brick walls everywhere. But, as Randy Pausch said in his last lecture, brick walls are there to separate the people that really want something from the ones not willing to overcome the obstacles.
At the conference, I spoke about how great it was to discuss about science and training methodology 24 hours per day for few years. Having strong debates, doing calculations, performing experiments, discussing and arguing with coaches and scientists filled my days at the time. That was proper “deep practice”. Everything was an opportunity for growth and such environment was what made Italian sport successful and innovative in those years. It was great, and I treasure every minute of that time.

In Abano I also met an old friend and had the pleasure of translating his lecture. The old friend is Professor Paavo Komi. Prof. Komi was another inspiring figure in my career. I went to “study” him in 1997 in Denver at the ACSM when I was a student in the USA for my Master. I had read all his papers and books and wanted to see/hear his keynote lecture as well as understand how somebody can prepare a scientific presentation about his data and showcase his work in front of hundreds of people without panicking. I quietly entered the empty auditorium while he was aligning his slides (for the youngsters, at that time PowerPoint was not really an option) and asked politely if I could see him preparing the talk. He was a bit puzzled at first, but then he allowed me to stay. That day I learnt how meticulous preparation has to be in every field and I was inspired to try to reach his levels of knowledge and positive influence on the strength and conditioning and scientific community.
In Italy I was asked to translate his presentation and I loved every moment of it, as the work he has done with numerous collaborators around the world has been truly amazing as well as being totally relevant to strength and conditioning. I also had lunch with Paavo and we chatted about past times as well the origins of the European College of Sports Science and how things have changed in this profession so quickly (for the good) in the last 15 years. We should be thankful to this group of guys. They had a vision and not much money (actually they had none...) and they created a great organisation to foster collaboration, innovation and education as well as a job market for our profession. It is amazing what people can do if their noses are pointing in the same direction.
Few lessons here. People and ideas drive innovation and change and help athletes reaching new heights. Facilities and gadgets help and support people and ideas. Not the other way around. Likeminded people willing to park the ego at the door for bigger achievements than personal self promotion can do amazing things. Lessons from the past are good. Experience helps in framing the path to the future.
There is a tendency these days to discard what happened in the past in every field. As well as a tendency to forget about the people which were there before and got their t-shirts. I guess it is a sign of the times. Old school is perceived to be not relevant anymore. I like old school. In particular if old school means application of basic, sound concepts with attention to detail.
I think we should make sure we know and understand well what happened in the past to learn and we should seek wisdom from the people who were trying to do what we do now years ago so we don’t re-invent the wheel. In our field we have still the same unanswered questions. We still don’t have 100% knowledge on how to individualise and maximise training programmes, we haven’t cracked the code on overtraining and fatigue and we still don’t understand fully what it takes to transform successful young athletes in winning performers.
So, if you are a young sports scientist, make sure you listen to the people teaching and mentoring you. They may sound old school, sometimes pedantic, sometimes a bit hard to deal with. Listen to them, there is a lot to learn and you will thank them ten years from now. Also, make sure you also read scientific papers published many years ago. Not all the recent literature is “recent”, lots of things have been done before and they are “sold” as new.
If you are looking for examples, go and read the work from Professor Angelo Mosso and look at his ergograph developed in 1890. You will find out that the use of dynamometry to measure fatigue is not a new idea after all.

Conference in Italy in November

It is always a pleasure and a surprise to be invited in Italy to speak at a conference. I left Italy many years ago to pursue a career in sports science and research and being invited back home to speak to coaches and sports scientists is always a proud moment and an opportunity to speak my first language again for few days.

The invitation this time has come from the Italian Athletics Federation and CONI for a conference called “Atleticamente”. I have been invited to present in a special session to celebrate my PhD supevisor and mentor Professor Carmelo Bosco. I am very happy about the invitation to this conference and proud also because Bosco’s supervisor, Professor Paavo Komi will be there.

Over the course of my career both Paavo and Carmelo had a great influence. I was always hoping to become as good as they are and have been and to this day they are still a source of inspiration and I feel privileged to have had the opportunity to meet them and spend time with them.

I will talk about my work with Prof. Bosco from the Lab to the field as well as my own research work on the present and the future of sports science in the applied setting.

The conference will be a great opportunity also to learn more about other sporting systems and catch up with colleagues and friends few months before London Olympics.

Good calories, bad calories and weight gain/loss

Time goes fast and I realized the blog has been abandoned for quite a while. I have been reading recently a little bit about weight loss, mainly to update my knowledge, and also for some personal interest, having suffered a broken rib and now trying to recover some shape!

My interest was initially on rapid weight loss. So I wend back to read some old papers on rapid weight loss and performance (e.g. Fogelholm et al., 1993 ) which showed for example that 6.0 +/- 0.6% of body weight was lost in 2.4 days by fluid and diet restriction and forced sweating, and when followed by a 5-h "loading" (food and drinks ad libitum) there was no change in performance with a gradual weight loss programme. However while in experienced athletes such approach might still not produce visible and measurable reductions in physical performance, it seems clear that psychologically they are highly likely to suffer (see Hall and Lane, 2001) as well as having some impairment in cognitive function (see Choma et al., 1998).

However, while looking for some literature on dietary aspects of weight loss I came across some interesting information.

First, two interesting books I just ordered: Good Calories-Bad calories  and Why we get fat from Gary Taubes which quite rightly points the finger to carbohydrates and their abundant use as the main cause of obesity. I will read the books and then write a review, as while I am keen to read his summary of the carbohydrate issue, I am not so convinced about his views of the role of exercise on weight management. What pointed me in that direction was a great letter written by Professor Tim Noakes on the British Medical Journal’s blog. As usual Tim has written some interesting comments. Have a look at it and make your mind up!

The internet is always full of surprises and while looking for information I have been impressed by the project of a personal trainer who decided to gain weight before losing it again to learn how it feels to be overweight and then to show how his methods work in getting himself back in shape. He started in May his weight gain plan and is due to start the reverse process in November. If you are curious about it, go read his blog here.

Epidermal Electronics

I have been recently reading a lot about epidermal electronics. Pretty soon patients in hospitals (and sports people) should be able to wear skin mounted electrodes to be able to measure a variety of physiological indicators in real time for a prolonged period of time.

The latest innovation comes from the University of Illinois. A new device looking like a tattoo, has been developed and proposed as an innovative smart skin solution. Researchers at the University of Illinois who came up with this device made circuits with a wide array of components, to prove it could work: sensors, LEDs, transistors, radio frequency capacitors and wireless antennas. The devices can draw power from induction or even from mini solar cells!

Inventors say they could be used for various medical applications, especially sensors that monitor heart and muscle activity, which currently require conductive gels and/or relatively bulky equipment. To prove it, they measured electrical activity produced by the heart, brain, and skeletal muscles, some data are reported in Science.

image You can also see a video of the technology below. Pretty impressive technology which will be hopefully available soon!

This is impressive technology, pushing the boundaries of wearable sensors and providing incredible possibilities for studying human movement.

Muscle oxygenation in-vivo

Our paper on the possibility of using Near Infrared Spectroscopy (NIRS) to measure muscle oxygenation in-vivo in elite athletes has now been published ahead of print by Medicine and Science in Sports and Exercise.

This study is the first of a series of studies constituting the PhD studentship funded by the BOA to study the possibility of using NIRS in the field as a tool to understand performance demands and adaptations to training as well as developing innovative portable integrated brain and muscle devices. The research programme is a collaboration between ourselves, the University of Essex with Professor Chris Cooper and Professor Clare Elwell at University College London.

The main author of this work is Catherine Hesford and you can find more info and contact details here.

More work will be published in the next months and I will write more about this fascinating technique soon on this blog.

The abstracts is available below.

Abstract
PURPOSE:

It has been suggested that due to the low sitting position in short track speed skating, muscle blood flow is restricted, leading to decreases in tissue oxygenation. Therefore wearable wireless-enabled Near Infrared Spectroscopy (NIRS) technology was used to monitor changes in quadriceps muscle blood volume and oxygenation during 500m race simulation in short-track speed skaters.

METHODS:

6 elite skaters, all of Olympic standard (age = 23 ± 1.8 years, height 1.8 ± 0.1m, mass = 80.1 ± 5.7kg, mid-thigh skin fold thickness = 6.8 ± 2.2mm) were studied. Subjects completed a 500m race simulation time trial (TT). Whole body oxygen consumption was simultaneously measured with muscle oxygenation in right and left vastus lateralis as measured by NIRS.

RESULTS:

Mean time for race completion was 44.8 ± 0.4 s. VO peaked 20 s into the race. In contrast, muscle tissue oxygen saturation (TSI %) decreased, and plateaued after 8s. Linear regression analysis showed that right leg TSI% remained constant throughout the rest of the TT (slope value = 0.01), whereas left leg TSI% increased steadily (slope value = 0.16), leading to a significant asymmetry (p<0.05) in the final lap. Total muscle blood volume decreased equally in both legs at the start of the simulation. However, during the course of subsequent laps there was a strong asymmetry during cornering; when skaters travelled solely on the right leg there was a decrease in its muscle blood volume whereas an increase was seen in the left leg.

CONCLUSION:

NIRS was shown to be a viable tool for wireless monitoring of muscle oxygenation. The asymmetry in muscle desaturation observed on the two legs in short-track speed skating has implications for training and performance.

Free reference manager and PDF organiser

I have not had much time to write on the Blog recently. London Olympics are approaching fast and there are too many things to do and too little time!

Anyway, I will write a short article to praise a recent addition to my software tools. Of course this is another freeware. All of us continuously struggle to organise all the PDFs of the scientific articles we read and also make sure we can site while we write articles. Commercial software packages are of course available, however I came across a great freeware solution: Mendeley. If you want to look at a short video to explain how it works, have a look at this video:

http://vimeo.com/user5499963/what-is-mendeley

I have downloaded and used the software for few days now, and it has been very easy to create specific folders and import PDF files arranging my references by topics.

image

The folder syncs with server space, so it is possible to keep all the documents and libraries if your computer crashes or if you lose it, as well as push the content to other devices.

It is also possible to annotate, highlight and share comments with others.

image 

Also, it is possible to create shared libraries so everyone can add and share comments as well as share the PDF contents. Finally, it is possible to create an online group to share knowledge on a particular area.

A great tool for anyone to use. The free version provides 500MB of space free and 500MB to be shared as well as the possibility to have 5 private groups ad 10 users. More space and more options are available for reasonable fees.

Curious? Download the software and find out more about Mendeley here:
