Skins A400 Men’s Compression Power Shorts

It is no mystery: even the most avid runner would give a leg (well, maybe an arm) to run the preferred distance with less effort. In the past, I already posted something about the training load and the relative rating of perceived exertion. One thing, though, should be clear without reading that article: good results are very likely to happen if the perceived exertion is low.
There is a company called SKINS that is taking this matter quite seriously since almost twenty years. Their philosophy is just simple: improve blood circulation and you’ll work harder, longer and recover faster. That sounds like the Holy Grail of anyone doing sports, right? Actually, this idea seems to be more than a legend. The fundamental principle is to use compression clothes for increasing the blood velocity by reducing the blood vessels’ cross sectional area. This should help reducing muscle soreness and speeding up recovery. To date, positive results are supported by a fair amount of peer-reviewed scientific literature. Moreover, I had the chance to test a pair of half tights. So here I am, a scientist in the role of Thomas the Apostle sentencing a poorly scientific “Except I shall see, I will not believe”.

The A400 Men’s Power Shorts.

The SKINS A400 Men’s Power Shorts are half tights that should be specifically “designed to maximise explosive power and increase strength and speed”. The compression technology they include is very well explained here, but the main message is the one I wrote a couple of sentences above. For sure, the first impression is mesmerising: the “JUST ADD SWEAT” printed inside a packaging worthy of containing a diamond necklace is simply a subliminal push to try them on immediately.
Pretty sweet packaging, right?

The first impression, I have to say, is kind of contradictory. These half tights are tight indeed! But come on, compression must exist somewhere in a pair of compression tights and after realising this key concept you basically forget to be wearing them. Mainly because they are freaking comfortable. No laces, no zippers, no rough elastic bands touching the skin and, yet, a very useful back pocket (you cannot close it since the lack of a zipper, but you are not going to lose anything, guaranteed).
During running, they feel great; the low waist is a right choice to help the freedom of movement. Until now, I have already put on a fair amount of hours in them and I did not have any problem with the fit. The size is very important; one should really take a look at the remarkably good sizing guide provided on the website. If you follow the guidelines, you will not place a wrong order.
About the improvement in performance, I do not have a lot to say, since it would not be fair to draw conclusions out of a one-subject, super-biased sample (tester, subject, writer and reviewer? Come on…). One thing is for sure: I am very happy with the half tights and I am so convinced that I would be very curious to try the recovery-specific products. To facilitate your work, I summarised hereunder all the important articles you can find on the SKINS science page. Have fun!

April 2015 – Training recap

Track season finally arrived. And with it, an incredible peak of tiredness through the second half of the month. Something very close to what the Germans call “Spring Tiredness” (wikipedia link) or, to be fair and formally correct, “Frühjahrsmüdigkeit”. Non-German readers: please don’t close the page now. It’s three words in one, nothing more than that, don’t be scared.
Anyway, despite this huge lack of forces that asked for more than one day off, I can definitely say I started with the right foot. First race over the 3000 m SC and personal best (10:15.75), simply controlling the splits and running as smoothly as possible. Nothing great, but another small brick in the wall before the intense month of May.
As usual, you can see all my training sessions details on the SportTracks mobi service.

March 2015 – Training recap

Constant commitment, a fair mileage and the first hurdles of the season: this was my March. During the last month I put together a lot of hills workouts and some speed on the road. In the last days, I started touching some Tartan: track season will start in the end of April.

February 2015 – Training recap

During last February I tried to cross train as much as I could, mainly by doing some XC ski. Moreover, I started to add some hills and 10k race-pace to my medium/long workouts. Not a huge running volume then, but quite a fair amount of aerobic hours.
As usual, you can see all my training sessions details on the SportTracks mobi service.

January 2015 – Training recap

After quite a disappointing 2014, January 2015 has been the month of long-term plans. Around 30 km on indoor track trying to put together some speed and a 3k race to test the goal-pace for the outdoor season. In addition, I was curious to try a 1k and so I did. No big plans, thus, for the indoor season, but a lot of motivation to build up the basis for the upcoming steeplechase commitments.
As usual, you can see all my training sessions details on the SportTracks mobi service.

How to publish your Garmin training data to other services with "tapiriik"

There is a new way to publish your training data on multiple services with just one click. And you know what? It’s completely free! The name of this great tool is “tapiriik”. At the moment it supports synchronisation of SportTracksGarmin ConnectStravaRunKeeperDropbox and TrainingPeaks.
With just a few settings you will be able to backup your training data on different databases.
The home page as it appears at your first access.
The login to each service can be done just once at the beginning, with the normal User+Password method. Saving the credentials will limit this operation at just the first access. After that you will just need to access tapiriik and do the sync.
To connect a service, just enter your login data.
The options you can manage are explained in the picture hereunder. You can simply decide, for each service, from and to which other service synchronise your data. In this example I decided to sync the other services starting from SportTracks, because that’s where I have my main log.

The “Options” window of each service will allow you to decide what synchronises what. Just click on the arrows under the “From” or “To” option to activate or deactivate the direction of sync.
If you suddenly decide that you don’t want to use one of the services any more, you can just unlink it under the options menu. Nothing will be deleted, in case you do it accidentally.
To disconnect a service just click on the “unlink” button in the options window.
Nothing will be deleted after disconnecting a service.

Some websites like Dropbox will require an “app authorisation”, like showed in the following figure. Also RunKeeper works with apps, so you will be asked for the same thing.

For some services, like Dropbox, the login comes as an external app authorisation.
Since Dropbox works directly with folders, you are allowed to choose where to save your files. Also the file extension (*.tcx or *.gpx) can be selected, like the naming system. Simply click on “Reconfigure” under the service icon to activate the options window.

In Dropbox options you can also decide the target folder, the file format and the file naming system.
After the general setup just click on “Synchronize now” to start the sync. If your database is large, the operation will require some minutes the first time. After that, if you will do it with a regular cadence (let’s say once every one or two weeks), the sync time will be less than one minute.

Clicking on “Synchronize now” will start the synchronisation between the selected services. Closing the window after this operation won’t affect the sync.
There is also the possibility, by paying just 2.00 $ a year (!), to have the synchronisation automatically done for you. Definitely a reasonable price, don’t you think?
Pros and Cons:
+ A service like this coming for free is absolutely good news.
+ Having the chance of using Dropbox is a remarkable step towards data ownership freedom, since the users can migrate their own data as they prefer (that’s also the philosophy of SportTracks‘ team).
+ Heart rate data, where available, are correctly transferred among services.
+ The website is very simple and usable.
+ The sync time has been improved a lot in the last months.
+ The following cons are not directly linked with tapiriik, but are the result of a great lack of standardisation between platform services.
– Strava doesn’t import no-GPS files; this is a problem for people doing indoor training sessions.
– RunKeeper imports no-GPS files, but sometimes doesn’t take into account the corrections made and you can often find activities with correct duration, but empty distance.
– Garmin Connect shows the same problems as RunKeeper does.
– In general, I’d like to see the corrections made on distance, since GPS devices often over-estimate distances.
Here you can find a list of my running-related posts. Now shut down the notebook and have a run!

Table 1 HTTD values for different running shoes.

Heel-to-toe drop: meaning and measurement

In a shoe, the “heel-to-toe drop” (HTTD), also called “heel-drop” or simply “drop”, is nothing but the difference between the heel and the fore foot height. Some people measure these values without including the insole, but I like more the approach that includes it (there is always an insole, so why forget about it? Moreover, some insoles have differentiated thickness from heel to fore foot).

Figure 1 shows the location of the outsole (usually the only part in contact with the ground, provides grip), the midsole (usually located between outsole and insole, provides cushioning) and the insole (also called insert, provides a small amount of cushioning and sometimes supports the arch of the foot).

Figure 1 Outsole, midsole and insole in a running shoe.

Typical values of HTTD can be classified (here you can find a list of some shoes I measured) as follows:

  • 0 to 4 mm – usually found in racing flats, “zero-drop” or minimalist shoes, generally low cushioned
  • 4 to 8 mm – usually found in racing flats or “low-drop” shoes, generally low cushioned, sometimes mid cushioned
  • 8 to 12 mm – current standard for fast training/long distance racing shoes, generally mid cushioned, sometimes highly cushioned
  • 12 mm or more – a common value for normal jogging/running shoes, generally high cushioned.

Measuring the HTTD is quite a simple procedure and can be done in many different ways. Here I will show you my method, that I found being very accurate and reproducible. Only a caliper and a reference frame are needed to complete the measurement.
As showed in Figure 2, after building an L-shaped reference frame, the first operation is to set the caliper to zero.

The first measure to take is the heel pack height (outsole+midsole+insole), as shown in Figure 3. The measurement point is exactly in the lowest area where usually the heel is.

The second and last measure involves the fore foot zone. During this operation you want to be sure that the outsole is touching the reference plane (normally running shoes have a quite strong curvature in this zone). Normally the measurement point is under the metatarsal area, at the centre of the foot.

The difference between the first (heel pack) and the second (fore foot pack) measure is the HTTD. Typical results are listed here.

2013 Track & Field season

Chronicle of a Steeplechase year

As said in last year’s end-of-season post2012 was my first season 10 years after quitting races. This year I kept on smashing my records (it’s so easy, when you start again from scratch), even if an Achilles tendinopathy tried to stop me. 

Taken from the athlete profile section, here’s a review of my improvements:

Outdoor progression of main events.

Some targets were achieved, some others just approached. I really wanted to run sub 10:10.00 in the steeplechase event, but maybe I forced too much in the first part of the season. I am very proud, though, of my improvements in longer distances.
Definitely the most important point is that I finally found a great team here in Berlin and I can say I picked up the right pace to start the winter season in a proper way. Carsten, Sebbi, Micha, Merlin…they were all very kind in relieving my forced stop. Not to mention, then, the great support I always had from mum, dad, Katrina and all the friends in Conegliano (Pie, Mattia and Gbo in a special way).

Last, but not least, the irreplaceable help from my technical partners has been again crucial. Brooks Running Italy and “himaxx” (Center for Altitude Training, Berlin) continue to follow my journey strongly. Thank you!
As usual, I tried to condense all the emotions, motivations and regrets in a single, short video. Nothing is better than direct experience to understand what lies under a whirling Track and Field year. But the images and the music itself are quite appropriate for trying to understand. 
So, again, welcome to my world. Enjoy and…keep on training!
