Tennis Instruction -How Important is it to Watch Tennis Video Lessons With Expert Comment?

Tennis in the last 25 years tennis has evolved from a tactical and strategical chess game to a straightforward, aggressive heavy topspin, right to left dominating by force rather than a skills battle.

This has given the illusion that the game is a lot faster than it really is, nevertheless if you are a student of the game and you want to improve your tennis stroke production or correct something in your shots and you need a good visual example, you are going to want to see some of the top players in action.

Of course you can tape some video on TV from matches played at the Australian Open, Roland Garros, Wimbledon or US Open and then go through hours of looking for the sequences that interest you but, without an expert commentary, you will be at square one.

Or you visit some of the websites on the internet that offer you video clips, most of them not for free, but it is one of the best ways to improve your strokes.

The best sites will identify the stroke, the most common grip types, the stroke description and give pointers on key aspects of the shot-making.

Most sites will allow you to play back or slow the action to a frame by frame replay that will show you exactly how the ball is hit , the swing is taken or how a particular type of footwork is used according to a specific situation.

The expert comment telling you what to look for and how to use it in your game is a great bonus to accelerate your learning process, with the advantage that you can apply the Tennis instruction immediately and in case of questions or doubts on the practice court, you can go back and review the material at your leisure.

So do not wait anymore go and look for a site with video lessons on it.

And enjoy improving your tennis!

Spontaneous Evolution - Learning From Our Cells

"You know, our cells just might be smarter than we are". Swami Beyondananda. "How can 50 trillion cells live in harmony and peace while a mere 7 billion people are on the verge of annihilating themselves?"

This is one of questions explored in the very interesting book I'm reading: 'Spontaneous Evolution' by Lipton and Bhaerman. They talk about the organizing principles responsible for the evolution of multi-cellular communities; their premise is that what works for the cell also works for the human, and what works for the human will also work for humanity.

The drive to higher efficiency and survivability led to the evolution of eukaryotic cells - communities of single prokaryotic cells. Over time, these evolved into close-knit cell colonies with individual cells performing essentially the same job.

As the population of these colonies exceeded a certain limit, it was no longer efficient for each cell to do the same job. Communal cells began to differentiate and specialize - delegating specific tasks to different cells.

Akin to craftsmen and their guilds, differentiated cells form tissues and organs whose products and services are required for the community's survival. For example, a cardiac muscle cell is a master of contraction - a process that is managed and driven by the many different organized guilds of cardiac cells that comprise the heart.

In exchange for their specialized cardio-vascular services, these cardiac cell guilds receive complementary services from other specialized cell guilds in the body - for example, nutrients from the digestive system, oxygen from the respiratory system, protection from the immune system, waste management through the excretory system and world news through the nervous system.

It's an important lesson: the success of these complex systems is a function of co-operation, not competition, among the cell guilds. The remarkable harmony displayed at the cellular level is the character that distinguishes successful cell communities from the current state of our human society. Each cell is an individual, yet they all behave and support one another.

A very interesting feature of the cell community is their equivalent of a monetary system. Adenosine Triphosphate (ATP) molecules are the currency of the cellular economy. Cells work to make ATP and expend ATP to do work.

Cells whose efforts are more vital get paid more ATP and may even be provided with cellular entourages that support their specialized functions. While cells are on different pay scales, every cell is provided with the basics of life: food, shelter, health care and protection.

Excess energy is stored in fact cells - the equivalent of regional and national banks. These reserves are available for the use of the entire community - at the behest of the body's government.

These reserves can be deployed anywhere within the system to build, upgrade, or repair the body's infrastructure. Cells, therefore, freely contribute to the efforts of the community without having to worry about where their next ATP paycheck will come from.

The human cellular organization has a R&D system that creates technology and manufactures biochemical equivalents of steel cables, plywood, circuitry and networks: an advanced environmental system for air and water purification; a superfast communication system right to the cell level; a criminal justice system that detains, rehabilitates and even assists in the suicide of destructive cells; full health care coverage and an immune system.

Will the Connected Age move towards true communities that collaborate will each other for the larger good? Will there be true interdependence as exemplified by our cellular communities? Do share your own thoughts and comments on this.

How Sometimes Ignorance In Tennis Is Bliss!

fter trashing Guillermo Canas 6-0, 6-3 in the MUTUA MADRILENA MASTERS MADRID 2007, Federer made the following comment; "I was especially disappointed with the Miami loss, so to beat him later in the year after two tough losses is nice."

To me that answer did not make one bit of horse sense! Why would Federer be upset to have lost in Key Biscayne, Florida (U.S.A.)? when the altitude is about only 3 Meters (9 Feet) above sea level, the courts are relatively slow, the balls do not move at all, the humidity and heat are unbearable, breathing is a torture, the wind blows from every direction, all in all conditions that highly favored a marathon type player from torrid and humid South America like Cañas, with an extremely low unforced error percentage (the so called "paparra"*).

Roger's more honest answer would have been "Yep, Miami hurt but Indian Wells hurt even more because I was playing under conditions that favored me, with an altitude of about 500 FT (167 M) and weather identical to my city of birth, Basel 853 FT (260 M), on pretty quick courts, with fast high bouncing topspin shots, rather low skidding balls on my slices and volleys, but in the end Canas still nailed me!"

In conclusion to the question, Roger Federer could have said; "Even though those two defeats hurt me, in Madrid at an altitude of about 1,969 FT (656 M) with all other conditions in my favour, fast moving balls high boucing on quick tennis courts, very low skidding balls on my slices on my attacks and volleys, plus the key factor of playing on an indoor tennis court which virtually and effectively reduces Canas defense capabilities by about 50% when the defense is indeed the core of his game, I knew that no matter how bad I played, chances were 95% in my favor that I would win." (Note- The 5% left in Canas favor would be in case of a Federer injury!)

This would have made plenty more sense to me, what about you?

In reference to "high altitude play" 1,800 FT (600 metres) is not a real challenge even though it does affect play, but anything at the 3,000 FT (1,000 M) and above sea level should be approached with much respect and longer then a 3 day preparation should be planned. As a tennis player here are some places to watch for; Mexico City, Mexico 7,349 FT (2,240 M), Quito, Equador, 9,200 FT (2,800 M), Johannesburg 5,751.3 FT (1,753 metres), Lima depending on location up to 5,079 FT (1,548 M), Gstaad 3'150 F (1,050 M) and a few others.

Altitude play can be a real curse or a blessing depending on how well you adapt and the type of game you play. Altitude training (sometimes simulated altitude in pressurized systems) is a blessing because, done the right way** and at the right times in the year, can lead to the natural gain of red blood cells which are so much in need for top performance.

The more an athletes body is at the top of its fitness, the greater care you have to take with it. In some ways an athlete's body is like the strings on a violin. As you fine tune it, the sound produced can be sublime, but, with the increase in sound quality, the risk of breaking the strings is much higher as well.

Of course there is a lot more to it then what meets the eye in tournament play. Knowledge of the conditions and quick adaptation to the environment you are going to play in; court surface, court size, back-drops, colours, wind patterns, tennis balls, lighting, sun position, shoes, racket string tension, clothing, sleeping plus drinking water, nutrition, mental preparation, regeneration and more...are all fundamental.

An early arrival of 2 to 3 days before the tournament begins allied to proper nutrition, physical and tennis training, can definitely make a huge difference in the outcome of your performance in a tennis tournament. The no respect of this rule at ATP/WTA professional level, many times leads to injuries and often to the surprise early exit of seeded players, who were late arrivals due to overloaded schedules, final play in a previous tournament and a myriad of other reasons.

In the tennis high altitude tournament play the scenario is no different, even though some believe if you can't train at altitude for at least two or preferably four to five weeks, prior to the tournament, your next best choice appears to be to compete immediately. But, since most athletes compete at their worst 24 to 48 hours after arriving at altitude, in my opinion you should keep in mind that everyone is in the same boat (exception, the ones born and who lived many years in high altitude) therefore an early arrival of at least 3 days before the tournament should be enforced and give you a small edge by passing the 48hr threshold.

As far as Federers comment, of course he knows what's going on, but he has to say something to the hungry press and certainly it will not be the real truth that he keeps for himself in the only place he can have true privacy for his pains and tribulations on the tour, his heart!

*In South America a tennis "paparra" is "el que passa mil y una pelotas (bolas)" the one that gets a thousand and one balls over the net without making a mistake. In short, "the tennis players nightmare"!

** For example, living at high altitude 6,000 FT (2,000 M) or above and training at lower altitude between 3000 FT (1,000 M) and 4,200 feet (1,400 M), with proper medical supervision (iron intake, VO2 max, lactates and other important controls), should bring the best results.

- NOTE WELL, this is NOT a training plan, nor advise for unsupervised athletes or anyone else. An individual professional training plan, professional advise and medical supervision before, during and after training is a must! DO NOT and I repeat, DO NOT try high altitude training alone, trying it alone can put YOUR LIFE AT RISK, so DO NOT DO IT without a highly qualified professional training team and medical support!
