NASCAR The Drivers Physical Conditioning

So does NASCAR driver physical conditioning matter. Some would debate that drivers are not athletes but one must consider the conditions inside of a stock car race vehicle. The interiors of these cars are not designed for driver comfort with air conditioning and surround sound. Everything about a stock car is focused on speed not on comfort. So NASCAR driver physical conditioning must be such that it builds a drivers endurance to withstand some harsh conditions and Gforces. And, the NASCAR driver physical conditioning is very similar to athletes in other sports except different areas are built up.

The temperatures in the drives cockpit of a race car can reach around 120 degrees Fahrenheit. Combine this temperature with a 500 lap race at 200 mph along with lack of air flow and you will see that NASCAR driver physical conditioning to build in endurance is critical. Plus, a NASCAR driver will need to steer and maneuver a 3,400 pound vehicle around curves, other cars, and over bumps. This can cause a lot of impacting against the driver plus just the strain of controlling the steering wheel. Then there are the G forces that will result from banking turns at speeds close to 200 mph causing pressure on the drivers torso as it presses against the side of the vehicle.

Oxygen is a problem too. Since the cars are very aerodynamic so as to increase speed, the air is guided around the car but does not reach the inside. The drivers cockpit is not pressurized like an aircraft. So, the driver has to be able to process what oxygen he gets very efficiently. Therefore, NASCAR driver physical conditioning will include aerobic exercises so as to optimize the processing of oxygen by the body.

Part of any good physical athletic training is the proper amount of nutrition and rest and NASCAR driver physical conditioning is no exception to this. By including the proper amount of nutrition and rest in NASCAR driver physical conditioning, the driver can maintaining alertness and quick reflexes which are crucial to a safe drive. Not getting the proper amount of rest can cause a driver to make mistakes which at 200 mph could be dangerous and even fatal.

Without the proper nutrition and rest in the drivers physical conditioning, a driver can become confused and disoriented during the race. This is especially true when combining the lack of air in the cockpit mixed with carbon monoxide fumes and tremendous G forces which cause disorientation as well. G forces can also affect vision but proper nutrition and vitamins combat against their effects.

NASCAR driver physical conditioning also includes weight training but not in order to build mass. The weight training performed by a driver is to build up strength for steering and breaking. It is also so that the drivers body can withstand the abuse from bouncing around and getting slammed from excessive Gforces.

NASCAR driver physical conditioning separates those who can make it for an entire racing event and those who would wear out during the qualification races. It is very important and the sport should be taken just as serious as any other professional sport.

An Explanation of The Physics of NASCAR

Even though NASCAR started as a backwoods illegal race to run moonshine, it has today evolved into a sport that is not only entertaining but depends on physics too. The obvious element in the physics of NASCAR is the aerodynamic design required by these cars in order to achieve top speeds of near 200 mph with the minimum drag coefficient. But there are other forces involved too such as Newtons Law of Motion and centripetal force.

Newtons Law of Motion states that a body will remain in motion unless it is acted upon by some external force. In outer space for example, in the absence of gravity, an object will go on forever. So there are forces that resist the movement of a NASCAR vehicle such as wind drag and another known as centripetal force.

Centripetal force should not be confused with centrifugal force. However without getting too technical, you can think of centripetal force as a real force acting perpendicular to the motion of the moving body. Centrifugal force on the other hand is actually a fictitious force and what we feel as we are thrown outward from a moving vehicle is the reaction force.

Centripetal force in the physics of NASCAR is crucial to keeping a car on the track. The tires of the vehicle provide the friction which is part of the centripetal force. The centripetal force needed to keep the car on the track cannot exceed the square of the speed of the car. To put it in simple terms, if the car takes a turn too fast, the wheels leave the ground and an accident occurs. The physics of NASCAR dictates that turns on the racetrack must be banked in order to increase the friction (part of the centripetal force) to hold the car.

Another component of physics of NASCAR that serves to keep the vehicle with all four wheels on the track during the race is center of gravity. Center of gravity is basically the point where you could balance the car on the top of a flag pole (theoretically). Racing vehicles need low centers of gravity in order to keep the weight close to the track. If a vehicle has a high center of gravity then it can lose control when it hits a turn much faster. Think of an ambulance with a high profile patient area. If the ambulance took a turn too fast, it would topple over. But if its profile was not too high, it could take the turn faster because the center of gravity is lower.

An ambulance needs the high profile in order to get patients in and treat them but the physics of NASCAR dictate the low center of gravity in order to apply more centripetal force and keep it attached to the track on a turn.

Then there is the machining of engine components in the physics of NASCAR that are important for building horsepower with the minimum of friction. You want friction when it comes to centripetal force but you dont want it inside of an engine. This is why internal engine parts are machined to within very accurate tolerances much more accurately than automobiles for family and everyday use. Why? It is because you want to minimize friction inside the engine. When engines torque at these speeds, friction is a very dangerous enemy.

Has F1 made overtaking too easy?

There have been five grands prix so far in the 2011 Formula 1 season and every single one of them, in its own way, has been a cracker.

The introduction of faster wearing tyres from new supplier Pirelli, the DRS overtaking aid and the return of Kers power-boost systems has led to a perfect storm of close racing, overtaking and pit stops.

This has made for an exciting season even though Red Bull driver Sebastian Vettel is running away with the championship after four wins and a second place in five races.

Yet there is disquiet in some parts of the Formula 1 paddock.

There is a purist view that what the world is seeing is some kind of pale shadow of what F1 really should be. Superficially the racing has improved, some are saying, but is it real? Is this F1 or a tainted, cheapened version of it?

After years of complaints about overtaking being too difficult in F1, about races tending towards the processional, about a general lack of entertainment, it might seem a somewhat perverse thing to say.

But the sense, in some quarters, is that in trying to spice up the show, the sport has veered a little too far towards showbiz and lost some of its true essence.

He is careful about he expresses it, but Vettel's team-mate Mark Webber is one of the chief exponents of this view.

Ironically, Webber has been one of the biggest beneficiaries of the new rules so far.

In China, where he qualified close to the back, the Australian used a clever strategy to benefit from the huge grip differences between new and old, hard and soft tyres, as well as the DRS, to climb up to third place by the end of the race, just seven seconds behind winner Lewis Hamilton.

So great was his pace advantage over his rivals in the latter stages that had the race been three laps or so longer Webber would have won. From 18th on the grid. In a race in which there was only one retirement. Even allowing for the superiority of the Red Bull, that is astonishing.

And yet Webber said afterwards that it felt a little hollow. Sure, he had enjoyed himself, and he was pleased with the result. But passing tough, world-class competitors such as Fernando Alonso so easily when they were effectively defenceless did not feel quite right. The racing, he says, is "less intense" than it was.

Webber brought up the subject again in Spain at the weekend, pointing out that the lap times F1 cars were doing on worn tyres and high fuel loads were only eight seconds faster than those of the GP3 cars, two categories down the motor racing ladder.

"We still need to be the pinnacle," Webber said. "We need to be able to push the cars to the limit throughout a grand prix and have very strong lap times, man against machine.

"Pirelli are working hard but we need to make sure the degradation and pace is still of a sensible magnitude and the cars can be put on the limit and not get too far on the showbiz side of things."

It's not just Webber, either. Last week, influential Ferrari president Luca di Montezemolo weighed into the debate, too.

Di Montezemolo said: "Listen, I want to see competition, I want to see cars on the track. I don't want to see competition in the pits.

"A little bit, yes - but in the last race (Turkey) there were 80 pit stops. Come on, it's too much. And the people don't understand anymore because when you come out of the pits you don't know what position you're in.

"I think we have gone too far with the machines, too many buttons. The driver is focusing on the buttons, when you have the authorisation to overtake. We have gone too far."

Much of the criticism has, as Di Montezemolo said, focused on the DRS. This is a clever device that moves a part of the rear wing, reducing drag, and therefore increasing straight-line speed.

A driver can use it in a specified zone on the track, on the longest straight, when he is within a second of the car in front at a predetermined point before the DRS zone. The driver defending his position cannot use it.

The idea was to make overtaking easier - but not too easy. The problem is that people have looked at the Turkish race, and the number of times drivers sailed past rivals down the long back straight, and concluded that DRS is making overtaking like driving past someone on the motorway.

That, though, is a misunderstanding of what is actually happening. In Turkey, as in so many of the other races, what promoted the overtaking was the differing grip levels of the tyres at various stages of their lives.

As Charlie Whiting, the race director, points out, in a lot of the cases in Istanbul, the driver behind already had a massive speed advantage over his rival even before he got to the DRS zone. Because his tyres were providing him with so much more grip, he could slingshot out of the preceding corner so much faster.

In those circumstances, the pass would have been easy regardless, DRS or not.

"Our view has always been we shouldn't make it easy, we should make it possible," Whiting says.

"In Melbourne we didn't have quite enough length (in the DRS zone). I think it worked perfectly in Malaysia and China. But we're all learning here. I definitely don't think we've made it too easy.

"I don't think anyone is under any illusion that it's the DRS that's allowing the overtaking. Opinions vary presumably, but tyres probably have a bigger part to play at the moment. I don't think we've gone over the top with the DRS, and we certainly don't want to. We've got no intention of doing that. We believe it's a good tool and hopefully you agree."

Although I share some of Webber's reservations, I also do not want to see fast cars stuck for ever behind slow ones just because the laws of aerodynamics dictate that drivers cannot follow closely enough to overtake. The DRS is a way of using technology to get F1 out of a hole that technology has got it into.

So, fundamentally, as long as governing body the FIA can find the right balance, I think Whiting is right on this, and the proof came in Sunday's Spanish Grand Prix.

Vettel spent the first 18 laps bottled up behind the fast-starting but slow Ferrari of Alonso. Red Bull tried to jump the Spaniard with an early first pit stop, but just failed when Ferrari responded and got out in front.

So they tried again and despite Vettel having to pass three cars on his out lap and Ferrari responding next time around, the German blasted past the pit exit just as Alonso was emerging.

Last year, with much slower wearing Bridgestone tyres meaning smaller pace differentials between the cars, Vettel would never have been able to pass three cars on his out lap, and he may well have spent the entire race behind Alonso.

At the same time, the difficulties all drivers had in passing down the main straight, the DRS zone, when they were able to pass elsewhere - around Turns Four, Five, 10 and 11, for example, where overtaking was previously very rare - proved that it was the tyres not the DRS that were making the difference.

"Barcelona had the possibility to be a drone-a-thon," Red Bull team principal Christian Horner said after the race. "Two years ago here, Sebastian drove around looking at the exhaust of (Ferrari's) Felipe Massa for the whole grand prix.

"This has really changed the dynamics of that and a track where it's traditionally difficult to overtake and produce close racing has produced an absolute thriller. The regulations have obviously contributed and created that. They're working."

It's true that the tyres' fragility is stopping the drivers exploiting the full potential of their cars all the time. This may not always be desirable but, as my colleague Mark Hughes points out in his column, this season it probably is.

If the cars were all on rubber that allowed them to push to the limit in the race, Red Bull would probably be able to tap into more of the speed that gives them such a huge advantage in qualifying. In which case Vettel wouldn't just be winning, he would be driving off into the distance. The tyres appear to be making the racing close, and introducing competition that might not otherwise be there.

Despite Vettel's domination, all the races have been close and exciting to watch and that is having a startling effect on the television audience.

You might expect, for example, that a German winning nearly everything would cause TV audiences to switch off in the UK, but in fact the opposite has been the case.

For every race this season, the BBC F1 audience has been significantly higher than last year. Malaysia and China had the highest number of viewers those races have ever had. During the Spanish race, the peak audience was 1.2 million higher this year than last.

But far more telling is the behaviour of the audience during the race. In the past, there would usually be a peak at the start, a significant dip in the middle, another peak at a moment of high excitement - a crash, a pit stop etc - another dip and a peak at the end.

This year, though, the audience has started higher than before - and stayed there throughout the race. People dare not switch off for fear of missing something. Far from the races being too confusing - as some newspapers have said - they are proving to be gripping from beginning to end.

I'll leave the final word to Jenson Button. He was asked if F1 had veered too far towards 'showbiz'.

"There are more positives than negatives," he said. "Of course it's a show; that's what any sport is. We need viewers to exist and the viewers have gone through the roof supposedly. I don't think we've done anything wrong. We've definitely gone in the right direction."

NASCAR Sprint Cup Series Tickets - Drivers Confident in GM Despite Troubles

Automobile giant General Motors announced last week that it may be filing for bankruptcy in order to stay in business, and while this is big news for all Chevrolet drivers in the NASCAR circuits, it doesn't necessarily mean doomsday is rapidly approaching for the racing world's top drivers. GM has already received billions of dollars in aid from the government but is still shaky when it comes to the company's future, sparking premature speculation that NASCAR is destined to follow suit.

With all this uncertainty looming, however, NASCAR drivers are coming out of the woodwork to voice their opinions on the current economic situation and especially on GM's role with the NASCAR Sprint Cup Series. Sprint Cup's No. 31 Caterpillar Chevy driver Jeff Burton recently made a statement with the USA Today concerning his views on the situation, saying, "My biggest concern as it relates to Chevrolet is freeing up credit and giving people the security that they want to buy a car, that they have a job. We can talk about Chevrolet but the real key is what is the overall economy? Chevrolet has shown for years that they're very committed to racing and that commitment is not going to go away."

Another Chevrolet driver in the NASCAR Sprint Cup Series is Kevin Harvick, the driver of the No. 29 Pennzoil car. Harvick backed up Burton's stance on his unwavering support for GM, recently stating "obviously, they are going through tough times, but they are in a wonderful restructuring process right now of putting their company back on their feet. I think when the economy turns they're going to be as good as they have ever been going forward. We're all here to support them."

Just as NASCAR's Chevy drivers like Burton and Harvick are calling for the support of General Motors as the automaker tries to uplift its current downward spiral, GM has also upheld the sponsorships it has with NASCAR so far. 12 Sprint Cup drivers including Burton, Harvick, Martin Truex Jr., Mark Martin, Casey Mears, Tony Stewart, Clint Bowyer, Ryan Newman, Juan Pablo Montoya, Jimmie Johnson, Dale Earnhardt Jr. and Jeff Gordon are all under the sponsorship of Chevrolet, and these top notch drivers aren't soon to be relinquishing their cars or titles for any reason. In the case that GM did file bankruptcy, a court of law wouldn't automatically cancel these sponsorships and other marketing activities because the publicity is good for the company, meaning that the contracts that these NASCAR drivers currently have with Chevy wouldn't necessarily be void should GM file for bankruptcy.

While economic turmoil and financial crises seem to be the talk of the town for now, the one thing that is for sure is that the show must go on. Gentlemen (and ladies) will still start their engines each week as the NASCAR Sprint Cup Series continues plowing through cities across the country, and NASCAR Sprint Cup Series tickets remain in high demand as racing season gets underway.
