In the sport of competitive cycling athlete's performance is increasingly being expressed in VAMs and thus as a power-to-weight ratio in W/kg. This can be measured through the use of a bicycle powermeter or calculated from measuring incline of a road climb and the rider's time to ascend it.
According to a study a human at 70 kg (150 lb) requires about 60 watts to walk at 5 km/h (3.1 mph) on firm and flat ground, [6] while according to a calculator at kreuzotter.de the same person and power output on an ordinary bicycle will travel at 15 km/h (9.3 mph), [7] so in these conditions the energy expenditure of cycling is about one-third ...
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 mountainous [citation needed] events.
The metabolic equivalent of task (MET) is the objective measure of the ratio of the rate at which a person expends energy, relative to the mass of that person, while performing some specific physical activity compared to a reference, currently set by convention at an absolute 3.5 mL of oxygen per kg per minute, which is the energy expended when sitting quietly by a reference individual, chosen ...
The last common alteration is the workload during the test. The original Wingate test used a load of 0.075 kp per kg bodyweight of the subject. [3] As these were young subjects, some suggest that adult subjects should use higher workloads, and several different loads have been used.
In this guide, Warloski and two other certified cycling coaches share their best advice for optimizing your indoor bike setup, including the mistakes you want to avoid, and getting the most out of ...

Bicycle gearing is the aspect of a bicycle drivetrain that determines the relation between the cadence, the rate at which the rider pedals, and the rate at which the drive wheel turns.
Some studies measure exercise intensity by having subjects perform exercise trials to determine peak power output, [4] which may be measured in watts, heart rate, or average cadence (cycling). This approach attempts to gauge overall workload. An informal method to determine optimal exercise intensity is the talk test.
