Aerobic Cross Training

Aerobic Cross TrainingDo you sometimes get bored with your aerobic exercise? Do you sometimes feel like you’re not getting the results you should from your aerobic exercise? If so, then you might want to consider the aerobic cross-training.

Aerobic cross-training refers to using two to three different types of aerobic exercise during an exercise session. For example, if you plan to exercise for 60 minutes, you might start with 20 minutes of walking or jogging, followed by 20 minutes of biking, and finish with 20 minutes of rowing.

Now, please don’t get the impression that you have to be in great shape to do this or that it has to be 60 minutes long. You can start with something as simple as a ten minute walk followed by ten minutes with an exercise video. This is cross-training too. You can gradually build up from there.

Here are some of the exercises you can use in your cross-training program; walking, jogging, biking, rowing, stair climbing, swimming, exercise videos, etc. Any combination of aerobic exercises will do. You simply go from one to the next with very little time between them.

Aerobic cross-training is beneficial to you in several ways:

It provides variety which eliminates the monotony often associated with doing the same exercise for a long period of time.

Less monotonous and more enjoyable. If your exercise sessions are less monotonous and more enjoyable, you are much more likely to exercise more often and for longer periods of time.

You are less prone to over-use injuries that sometimes occur from doing the same exercise movements over and over again.

You tone more muscles because you are using more muscles. For example, walking tones mostly the lower body muscles and rowing tones upper body muscles also. Even exercises like walking and biking that both tone lower body muscles, tone them at different angles and each tones some small muscles that the other doesn’t.

Aerobic conditioning is very specific to the muscles being worked. For example, you can walk ten miles a day and still be somewhat breathless after climbing stairs because you haven’t trained the muscles for that specific movement. Aerobic cross-training allows you to develop more comprehensive aerobic training.

Aerobic cross-training is effective for weight loss because you are toning and training the fat-burning systems of more of your muscles. It turns more of your muscles into 24-hour fat-burning machines! You are also more likely to exercise on a regular basis and for longer periods of time. This also promotes weight loss and fitness.

Choosing the Right Kart Frames

Choosing Go Kart FramesChoosing the right frame for your go-kart can largely depend on the surface you are riding on. Whether it is asphalt, concrete, or dirt – different types of frames behave differently according to surface. For example, dirt track frames should consist of a short front rail and a longer back rail.

Dirt tracks place a lot of stress and challenge on the front rail and stiff back rails zipping through dirt can cut power to the engine while cutting a turn. The best frame for riding dirt tracks are ones with narrow fronts and longer backs, vice versa to asphalt and concrete.

The A-1 performance of a frame largely depends on tire traction as well. Low traction tires (tires that do not “stick” well to the ground) are not grooved enough to withstand the rigors of the surface, rattling the stiff frame to oblivion. It also causes uneven weight transfer throughout the go-kart, and that is a no-no for maintaining optimum control of your money maker.

Consider this scenario: you have two pairs of roller skates. One has wheels half-an-inch in width and the other has 3-inch-wide wheels. Which pair would provide better balance as you roller skate? If you love mathematics, treat traction as a formula with the equation: traction = stability. Go ahead; transform yourself into a karting aficionado with this valuable piece of knowledge!

A major issue among karting enthusiasts is the durability and longevity of flexible frames. Exposure to punishing breaks and turns, along with the grueling hits to track walls every now and then, can distort the frame which cannot be “popped” back to its original condition. Experts recommend replacing frames every year.

There are many maintenance techniques you could practice on your kart to keep flexibility intact like running your kart through a course backwards. Racing a kart using the finish line as your starting point and your starting point as the finish line will have a “reverse effect” on the frame, shaping it opposite of what it would be shaped if you were racing the course normally. It’s like turning back the hands of time on your speedster!

The question over choosing the right go-kart chassis boils down to flexibility. High traction tires and a stiff frame is a recipe for disaster, causing your machine to turn stiffly and generate strenuous effort on the curves. Low traction tires will cause uneven weight transfer and break apart your frame like bread crumbs.

Options for frames mainly depend on what type of go-kart you’re riding, as each go-kart and their engine work best under certain scenarios. Stiff frames are a staple of 2-cycle and 4-cycle engines and flexible frames are found with higher horsepower engines. Remember, the more rigorous the circuit, the more flexible a chassis should be!

Go Kart Frames

Go Kart FramesKarting enthusiasts emblazon the image of the perfect chassis in their minds: lightweight, yet powerfully durable material capable of launching a kart forward without the slightest wear or tear. And along with perfect frames comes perfect tires, tires “grooven” to perfection providing the finest traction and downright freakish controls when running the curve.

Let’s discuss the intricacies and place a perspective on frames for your go-kart. The chassis as it is called in professional and enthusiast circles is by far the most important piece of this machine. The construction is paramount in maintaining a solid go-kart. What constitutes a frame? Think of a frame simply as parts holding a component together.

In the case of these speedsters, the frame is welded together by torsion bars. Stiff frames are a result of shorter bars crossed together, and more flexible frames are associated with longer bars.

Stiff frames that do not provide flexibility were the backbone of earlier go-karts and broke down easily. First off, simpler go-karts do not have the specifications needed (most important, suspension and tire traction) to ease the punishment frames go through while turning, accelerating, and stopping. Running on 2 or 4 cycle engines does not help compensate the health of a frame.

A lack of traction on your tires will cause uneven weight transfer and stability on your frame, ripping one or both sides loose at the same time. In essence, the frame is responsible for determining how well your vehicle moves zipping on asphalt, concrete, or dirt – dictating your performance on wide turns and shorter turns.

A sturdy, well-built frame is the key to maneuvering well on the track, especially when turning. Although a go-karts frame supposed to be resistant to the rigors and demands of punishing your go-kart as it explodes forward, but the most important criteria for an excellent frame is to negotiate turns well. Frames are directly responsible for how well go-karts turn left and right.

Weaker go-karts with cheap components are known to slide and drift along turns – in some instances, flipping to its side entirely with careless driving. “Side bite” is referred to keeping a go-kart planted to the track without sliding. Without the proper frame, go-karts will maneuver out of control, even shutting off in some cases due to over pressure to the engine.

The design of the go-kart chassis has everything to do with how well it moves on turns and maintaining side bite. If the width of the rear rails (go-kart frames constitute front rails and rear rails) is narrow, with measurements ranging from 24¨ to 25¨ – from “kingpin” to “kingpin”, the ends of the rail – it will have less side bite. Wider rails barely ever exceed 30¨ on standard go-karts.

The dynamics of the front and rear rails can be effectively pictured using this example: suppose you had two bottles – a two-gallon jug and a 16 oz. Water bottle. Giving it a swift, hard poke to its side – which container has the best chance of tipping to its side? If you guessed the water bottle, you guessed right! Wider rails provide stability and “foundation” while turning, reducing the side bite overall.

Formula One Racing, the Sport with High Advance Technology

Formula One RacingFormula One Racing is, quite simply, the paramount of karting. It is the professional form of the sport in its entirety. Formula One is an international phenomenon, a media conglomerate that rakes in millions and millions of dollars a year from advertising, sponsorship, and broadcast revenues.

Professional drivers with millionaire bank accounts race these majestic kart marvels that are unprecedented, flush with technological luxuries – everything from hard to produce lightweight frames that glide the machine to tires with unsurpassed grooving style that exemplify powerful movement on the circuit.

In order to better become acquainted with Formula One racing, we must understand its organization. Formula One is divided into drivers & their respective teams. Under such trademark car companies like Renault, Ferrari, and Toyota – each driver has an assembling cast of staffers consisting of mechanics, engineers, and designers all working towards one goal: to make that speedster faster using all the resources at their disposal.

Headed by team bosses that are adept at creating sponsorship opportunities and assembling the best cast for each team, Formula One employs the finest specialists in the business with backgrounds in computer and automobile – even specialists with aerospace experience! High end, (rare technology reserved for space projects) in some instances, create the fastest and most efficient car possible.

Formula One cars can be summed up in two words: technological marvels. These sleek, low riding gems ripping through laps at speeds topping 200 mph. consist of more than just a chassis, an engine, and four wheels. For starters, the engine is located behind the cockpit as opposed to standard automobiles.

They consist of 10 cylinder engines that produce heat which propel the kart forward. Team engineers are always looking into ways to make their engines more powerful. Currently, 1000 bhp (a scale for horsepower) has not been topped – it is up to the teams to produce an engine which would fare well supporting speed as well as support the chassis.

Construction of Formula One race cars is unprecedented. The first rule of thumb in designing a bonafide piece of framework is to make it weigh as least as possible. Less kart weight correlates to faster speeds. For this reason, team brains use lightweight material that is hard to construct.

The minimum weight of a kart must be 600 kg including the driver. This ensures a level playing field, although teams are allowed to keep their money making construction methods a secret from other teams. Team staff is very highly regarded in the Formula One business.

Their technological and dynamical know-how of the machines they build is a valuable asset to any team. And like free agents, they are lured and signed by the likes of companies creating a recruiting war for their services.

Of course, there are restrictions for creating karts. You cannot add nitro boosts to your machine or use technology that resembles life in the year 3000. Teams are always looking to bend the rules slightly and coming up ways to beat the competition legally.

Professional kart tires have to have optimum characteristics to ensure smooth driving. For one, tires have to have grooving technology built into them. For the novices, grooves are indented lines in tires that allow for it to slow down considerably on turns and to adapt to the track surface.

No matter what the technology, kart tires are simply not adept at withstanding the rigors of asphalt, concrete, and dirt. For this reason, Formula One racers are allotted two pit stops during the course of a 57 lap race to change tires.

If you’ve ever watched a Formula One race, team staffers with lightning quick hands have an extremely limited time for which to remove and replace tires in the pit stop – often times not exceeding over 7 seconds! Regulations are placed on tire grooves (a minimum of four) to allow for an even playing field for all racers. Remember enthusiasts, grooves serve more to slow down the kart than to speed it up.

Chassis construction with its illustrious carbon fiber material, tires with indented grooves, team specialists with a knack for speed, and engines which burn heat like calories is the epitome of a Formula One race car.

All of these attributes contribute to the performance of the vehicle in racing lap after lap. As a result of all this technology, Formula One cars leave people breathless reaching consistent speeds of 200 mph. on the race track. More impressive is the time needed to go from 0 mph to 100 mph – 5 seconds!

Formula One is only moving forward with the advent of new features – like improved horsepower engines, more lightweight materials, new ballasts to add weight to the car, and more. Behind that stylish, mind blowing chassis that pique our interest is that top-class technology that makes Formula One racing so great.
