To Boldly Go ...

I offer this thought to give us a sense of perspective.

Voyager I was launched in 1977, and has traveled approximately 11 BILLION miles since then, and is now leaving our solar system (hyper technically our heliosphere), into inter-stellar space (again hyper technically after passing through the Oort cloud). This marks the first human made object to do so in our history ... our complete history.

Traveling at about 38000 miles per hour, it will next come into contact with a star system in about 40,000 years.

Voyage II is right behind it at about 9 BILLION miles and take another 5 years or so to get out there.

Makes me feel a bit smaller ... and also awed at what we can accomplish as a species.

It's HOT Out There

Playing Matches in the Heat: Dehydration and Performance

Often matches are played in hot, humid conditions. In this environment, the body attempts to cool itself by increasing the sweat rate. Unfortunately, the fluid lost through sweat can lead to dehydration. Laboratory research has shown that even mild dehydration can impact physical performance, reducing strength, power and endurance. Researchers from the United Kingdom and Denmark approached the question of heat, dehydration and performance in a different manner. They took their experiment to the pitch and asked if competing in the heat influences post-match physical performance. Their results show that playing elite, competitive matches in a hot environment adversely affect explosive performance and that the change in performance may be linked to dehydration. ...

Kicking Back Comments: As we in the North East US have recently experienced, we have gone from winter to full blown summer with temperatures and humidity in the 90's the last few days.

I can not stress enough in how a referee is an active participant in a match as too should consider themselves an endurance athlete.

As such this requires exercice, diet, and hydration concerns to be successful.

While this particular article details the concerns and dangers of dehydration, particular attention should be paid as well to caloric intake and exertion level during a match.

An additional wrinkle in this, is a referee should also be aware of the signs of dehydration, as the referee is not only responsible for themselves and their crew, but for levels that do not have a trainer or medical staff available, a referee can certainly point out to the competent authority (e.g. coach) if they feel a player is in distress.

You always want to finish with 11 a side folks. A good referee, at all levels, works to keep it that way.

Lightning Strikes 3 Times!

Well friends, you know the old saying that lightning dosen't strike twice in the same spot, well it happened to me three times today! Please let me explain.

By the way, before I really get going, the expression is just a myth as it is fairly common for lighting to strike more than once in the same spot. NASA did a study on it.

So there I was minding my own business at work today, and having, well, a work conversation. The discussion was wrapping up and near the end of it, the person whom I was talking to said "... I like your blog ... ."

I always get a little sheepish when someone says that outside of the "soccer mainstream" as I'm never quite sure what reaction I am going to get as I can be somewhat ... well opinionated.

We spoke for a while actually, and I was truly flattered they took the time to read and enjoy the subject matter and gave me some good advice that I will share below.

Walking back to my office I though that was pretty neat, I'm glad others enjoy reading this stuff, heck that others are actually reading this stuff.

From there I struck up an online conversation with a colleague from the UK who I had not heard from for some time, and always enjoyed his wit regarding technical matters. Near the end of the conversation, lighting struck again and they too mentioned my rants on my blog.

This one I found not only really humbling, but also pretty darn accurate as the classification of a "rant" I think is more in line with what I do here. But again, in the same day, lightning strikes again.

On the way out for the day, I was stopped in the hall by another colleague, who made mention of my refereeing past and association to The Game. I was again blown away, and struck for the 3rd time in the day.

While I stumbled over the question I was asked, my head was racing with thoughts of "oh crap I really have to be careful about what I'm writing if folks are actually reading stuff."

There are days I sit here and ask why would anyone read this stuff ... even I can't stand to read it some days. Today was one of those days that I was truly humbled by the reaction from folks reading Kicking Back.

For those who have read, and those who have responded to me, positive or negative, I thank you, and remain humbled by your viewership.

Now the really good piece of advice I got was when I shared that there are times that I have strongly considered keeping this blog away from any "professional" sites, such as LinkedIn where many have received these updates.

This individual just looked at me and said, "It's who you are ... nothing wrong with that, right?"

And they are right.

For all the warnings that I have tossed out here about acting responsibly in front of cameras and how bad things can happen if it goes horribly wrong, there is another side to that.

It is also an opportunity to share with a far wider audience what makes one tick, and gain perspective about who we are.

Challenging, and a little frightening to be sure. But one with the right amount of tempering (sorry folks still can't go off the deep end here) I am coming around is a very positive thing.

I learned a lot today ... that NASA did a study of lighting events (I already knew it could strike multiple times in the same place) ... and that some appropriate sharing, is not such a bad thing.

It won't stop me from railing about Sepp ... but at least you'll know it comes from the heart =)

Physically Impossible?

Why the ref cannot get offside decisions right

It is just as football fans always suspected. Referees' inadequate eyesight means they can never be sure of getting offside decisions right.

But it may not be the officials' incompetence that is to blame, despite their reputation for needing glasses or a white stick. A soccer-loving GP argues that the rule which has ruled out so many goals should be scrapped because human eyes are just not up to the job of collating all the information needed for split-second verdicts.

Francisco Belda Maruenda, a fan of Real Madrid and his local teams, says applying the offside rule correctly "is beyond the capacity of the human eye, which may explain why so many offside decisions are controversial". In an article in the British Medical Journal today, he suggests the use of freeze-frame television.

But he told the Guardian: "It is obvious that television can be just used in the case of international matches or in Premier League matches but not in the case of regional or young leagues. That is why, as the offside rule cannot be applied scientifically, it should be removed." ...

Kicking Back Comments: I don't buy this on two levels. I don't doubt the science that eyes can not be four places at once, but I would opine they do not need to. (You can access the full article from the BMJ here (subscription required).) First of all, you can always listen to when the ball is struck to determine when you will judge the offside. This can usually be done even at large stadiums. There are times however that this is not possible due to crowd noise, or a subtle touch.

Assuming however that you can not hear what is going on, what is an AR to do in the case of having multiple things to look at?

Well, assuming the entire play is not in the field of view of the AR, and keep in mind, scientifically, the field of view for a human is pretty large (The approximate field of view of a human eye is 95° out, 75° down, 60° in, 60° up. About 12–15° temporal and 1.5° below the horizontal is the optic nerve or blind spot which is roughly 7.5° high and 5.5° wide.[source]), the AR must take "snapshots in time" and infer if a player is offside or not based on ball and player movement. All of this in a second or two. In short, the AR has to put several pictures together to make the call.

A GUESS YOU GASP!

No, a reasonable inference based on actual information the AR observes.

It's not easy, and takes lots and lots of practice, but in the case where you can not see everything in one "look", this is what an AR must do to get the call right. This is the magic of the highest level ARs who can do this and get it right.

This may make some folks uncomfortable, especially Mr. Maruenda I would imagine, but guess what, referees don't actually see everything and still make correct calls based on the other (than visual) information given. It is what makes a good referee, a great referee. This is a part of The Game folks, and frankly it is a wonderful thing that a referee has the freedom in the LOTG to "fill gaps" with reasonable inferences to manage a match.

Second place this goes off the rails is the suggestion that Law 11 should be "removed" because it " ... can not be applied scientifically (at all levels)." To which I say nonsense.

Ignoring the approximate 164 years of history with the offside law, to suggest it should not be enforced because the application lacks "scientific basis" (that's really the wrong term as it does have a scientific basis ... a better word may be "precision") I say is nonsense too.

The Game is not a mathematical equation that has a finite outcome, it is a series of interactions and subsequent reactions that unfold before everyone eyes. The Game is art, not science.

That to me is why, it is truly The Beautiful Game.
