Emulating aerodynamic drag of a user of an exercise bike

An aerodynamic drag emulation system for emulating aerodynamic drag of a user of an exercise bike having a pedalling system subjected to a variable resistance, wherein the system comprises a processing device configured to:

• interface with each of
• a set of sensors, and
• a control unit adapted to modify said variable resistance;
• and
• repeatedly perform a series of steps comprising:
• processing sensor signals received from the set of sensors, wherein, in operation, the latter are worn by the user as the user trains on the exercise bike by actuating the pedalling system, whereby the sensor signals are dependent on a body posture of the user;
• based on the processed sensor signals, computing a quantity, which depends on the body posture and determines an aerodynamic drag;
• generating a control signal encoding the computed quantity;
• and
• transmitting the generated control signal to a control unit for it to modify said resistance in accordance with the transmitted control signal.

A computer program product for emulating aerodynamic drag of a user of an exercise bike having a pedalling system with a variable resistance, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by processing means of a processing device to cause the latter to repeatedly:

• process sensor signals received from a set of sensors worn by the user as the latter trains on the exercise bike by actuating the pedalling system, whereby the sensor signals are dependent on a body posture of the user;
• based on the processed sensor signals, compute a quantity, which depends on the body posture and determines an aerodynamic drag;
• generate a control signal encoding the computed quantity;
• and
• transmit the generated control signal to a control unit for it to modify said resistance in accordance with the transmitted control signal.
