Introducing the groundbreaking AEROTEKK Variable Pitch Resistance air displacement system! This revolutionary patented technology is about to transform the way you train, elevating your fitness journey to unprecedented heights. Imagine a system that offers an expansive resistance and power spectrum range, allowing you to unlock your full potential like never before.

With VPR, you'll experience a whole new level of versatility. Train with minimal air resistance for lightning-fast movements or ramp it up for intense, high-force workouts. The possibilities are endless, as you explore the vast range of training options across the power spectrum.

Say goodbye to limitations and hello to a world of endless possibilities with VPR. Whether you're aiming for explosive speed or brute strength, this cutting-edge system has got you covered. Get ready to unleash your ultimate fitness potential with VPR – the future of training is here!

Conventional Air Displacement exercise equipment is already extremely popular and widely used in training ergometers due to its unique advantage of effectively automatically providing accommodating resistance in response to changing movement speed and resulting flywheel speed. Furthermore, unlike all conventional friction and magnetic resistance systems, air displacement resistance uniquely and positively increases flywheel inertia in response to increasing flywheel speed.

To a very limited extent the resistance range capability of air displacement ergometers can be somewhat increased with the addition of an adjustable air vent to allow for a variation in air availability to the flywheel, thereby changing the air resistance drag factor.

Now the revolutionary patented Variable Pitch Resistance (VPR) air displacement system takes training to a whole new level by providing an exponentially greater resistance and power spectrum range that facilitates training options across a massively wide power spectrum, with the option to train with extremely low air resistance for very low load or very high speed training, as well as the ability to also utilise extremely high air resistance loads for very high force and/or low cadence training.

VPR AIR technology changes the pitch angle of exercise equipment flywheel rotors, relative to the flywheel hub direction of movement. The changing rotor pitch angle changes the angle of attack and fluid (including air and water) dynamics interacting with the moving flywheel, exponentially increasing the range of air being displaced and the subsequent potential work resistance.

With conventional air resistance flywheels there is already a cubed relationship between flywheel speed and the power required to facilitate that change in speed. So, for example, doubling the speed of a conventional air resistance flywheel requires an eightfold increase in power (2×2×2=8).

However, with revolutionary VPR technology, above and beyond this normal cubed effect, the power required to move the flywheel changes dramatically even without changing the flywheel speed, simply by changing the pitch of the flywheel rotors and thereby changing the frontal surface area of the rotors that is now working against air resistance.

With zero pitch and only the thin leading edge of the flywheel rotors creating air resistance, the amount of power required to move the flywheel is absolutely minimal. But as the pitch of the flywheel rotors increases, a higher total surface area is pushing air, thereby requiring increasing power to maintain even the same flywheel speed.

On VPR ergometers, within typical workout speed and load parameters, even at a given fixed flywheel speed, up to 10 to 30 times more power is required to move the flywheel at maximal versus minimum flywheel pitch positions, depending on the given constant flywheel speed of movement.

When you then also take into account the normal cubed relationship of power to speed of air movement dynamics, when doubling the flywheel speed in VPR ergometers, instead of an increase in required power by a multiple of just 8, the additional power required may potentially increase by multiples of well over 200.

Accordingly, VPR technology facilitates the ability to work with both much lower and massively higher resistance loads than are normally available to the user on conventional air displacement exercise equipment. This therefore effectively provides the means to both find your most effective and efficient power production ‘sweet spot’, as well as also giving you the scope to train at the extreme ends of the power, force and speed spectrums to most effectively target and train both speed and force components of the power matrix.

This means that on the same machine it’s possible to do extremely light over speed work (or cater for users requiring very low exercise loads) and at the same time have available to you extremely heavy loads to cater for even the biggest, strongest athletes, or alternatively facilitate low speed work at high loads (similar to riding a bike at a very low cadence up a very steep hill).

VPR allows the user to find the optimal resistance load at whatever workout cadence they choose. For example, most competitive cyclists pedal most efficiently at a pedalling cadence of 80 to 100 rpm and VPR technology facilitates that perfectly at any fitness level (from absolute beginner to world class athlete), no matter how large or small the cyclist is. VPR also allows the user to adjust the load to perfectly simulate the feel of hill riding, no matter what their body weight is.

Whilst to a very limited degree this is arguably possible in a sense with other various forms of friction and magnetic resistance, the big difference is that with those alternative forms of workload resistance, as the resistance increases, inertia (momentum) proportionally decreases, which is both psychologically and physiologically draining and perceptually extremely de-motivating and soul sapping. But with VPR fluid dynamics resistance you can increase the workout load as much as you want and not lose any inertia, thereby dramatically enhancing the feel of the exercise movement. The weighted flywheel rotor tips and high flywheel gear ratio on VPR AIR machines even further enhances the inertia and positive feedback loop feel. The harder you go, the better it feels and the more you want to keep going. Better results for everyone, with less perceived effort.

Patented VPR AIR technology is available in two different formats - standard VPR, which uses two adjustable pitch flywheel rotors and the advanced VPR version, which has four adjustable pitch flywheel rotors.
