In fact, you are much more likely to have a de-trained person puke from an Assault Bike workout than get sore. However, the Assault Bike virtually eliminates eccentric contractions, so you don’t get sore from it. Unaccustomed eccentric contractions (catching/lowering movements you aren’t used to) are what cause muscle damage and DOMS (delayed onset muscle soreness). Think about the lowering phase of a squat, a pull-up or a press: that’s an eccentric contraction. An eccentric contraction is when the muscle is lengthening as it contracts. Make sure to account for the athlete’s overall body size (weight and height) into account before making these assumptions.Īnother reason why the Assault Bike is an effective tool is there is virtually no eccentric contractions involved. If a person has incredible power on the bike but isn’t strong with other implements like a barbell, it probably means they lack the mobility and skill to be able to express their true potential.Ĭonversely, if an athlete does well with high-skill movements like muscle-ups and snatches, but can’t get up to speed on an Assault Bike sprint, it could mean that their mobility, skill, elasticity and overall efficiency is high (optimization), while their raw metabolic capacity is low (adaptation). This actually makes the Assault Bike a great tool for identifying mobility restrictions. The second reason almost everyone can express their capacity on the Assault Bike, is because every joint involved moves through a ‘neutral’ range of motion, meaning it never approaches an extreme or end range. For one, this is because both the arms and legs are used, allowing the heart rate, respiration and general fatigue to climb quicker than local (muscular) fatigue when compared to other exercises. CrossFit Games, Sanctioned Events, Local Competitions).īecause there are very little mobility requirements, almost everyone can express their capacity on the Assault Bike. Until the AirBike can be universally standardized, it will be reserved for competitions that have a fleet of bikes within the same model (e.g. The fact that so many CrossFit competitors own different brands of AirBikes, combined with the fact that there are discrepancies within the same brand, is the reason why we haven’t seen an AirBike in online qualifiers like the Open yet.
Newer models (2nd and 3rd Gen) of the Assault Bike are more resistant to damage, and therefore registered power output tends to be more similar bike to bike. This is largely due to warping of the fan blades so they create less drag as they cut through the air.
Each model measures units (distance, wattage, calories) a little different.Įven within the Assault brand there are discrepancies between individual bikes.Įach one uses the same algorithm and therefore shows the same wattage at each corresponding RPM (Revolutions Per Minute), but heavy usage during a bike’s lifespan frequently result in older models being easier to pedal while registering the same wattage and RPMs. Not all AirBike brands can be created equal. Since the Assault Bike is the most commonly used AirBike in the Sport of Fitness, I chose to break it down rather than other brands, such as the Rogue Echo Bike or the Schwinn AirDyne.
