also stated that VAM values exponentially rise up with every gradient increase. For example, a 1180 VAM of a 64 kg rider on a 5% gradient is equivalent to a VAM of 1400 m/h on a 10 % or a VAM of 1675 m/h on a 13% gradient. Ambient conditions (e.g. friction, air resistance) have less effect on

VAM is a parameter used in cycling as a measure of fitness and speed; it is useful for relatively objective comparisons of performances and estimating a rider's power output per kilogram of body mass, which is one of the most important qualities of a cyclist who competes in stage races and other

The acronym VAM is not truly expanded in
English, where many think the V stands in some way for vertical, and the M represents metres, for instance "Vertical Ascent Metres/Hour." Ferrari says,
