![]() ![]() Air resistance: Wind resistance is the force, which acts in the opposite direction to the motion of an object moving through a gaseous medium (in this case, of course, the air).Rolling resistance decreases with higher speed. Rolling resistance increases proportional to weight, which is why it makes sense to analyse the power to weight ratio when comparing different athletes. Rolling resistance: Rolling resistance refers to the force created when a wheel is in motion, which acts against the direction of the movement.This can be calculated using our calculator, which also takes into account two further values. Climbing performance (gravity): The climbing performance is the power which is produced at a particular gradient.The following factors affect the power output: This will allow you to accurately compare the calculated values every time. Efficiency of the calorie expenditure corresponds to a trained athlete (more on the subject of calorie expenditure can be found in our calorie calculator - coming soon)įor best results find an appropriate route section, on which you can start up consistently.The most uniform possible gradient over the whole measured route To ensure the most accurate possible result, we make the following assumptions: Our cycling wattage calculator can never be as accurate as a measuring system installed directly onto a bike, but the values provide acceptable approximations. The pulse can also be affected by many different factors, while the power output can give an indication of the actual training stress. The pulse is very slow to react and only reaches the target value after several seconds, while the power output adjusts instantly. If you only want to measure your own capacity, knowing just your power output is sufficient.ĭetermining your power capacity in watts can be an advantage, as it is significantly more precise than using your pulse. This makes it easier to compare athletes of different sizes. Relating power capacity to weight can be beneficial, as rolling resistance and wind resistance are also affected by weight and so are effectively factored in automatically. But you don’t need to fork out for high-tech equipment our calculator will help you work out your individual wattage. Watt measuring systems offer significant advantages over the pulse for training control, but are more expensive and therefore mostly used by amateur and professional athletes. This provides a relatively accurate indication and point of comparison, by which you can measure your training progress. In cycling today it has become commonplace to measure the training performance in watts/kg (power to weight ratio).
