Watt (W)

Watt is a term used to measure the rate of energy (kinetic) transfer equivalent to 1 ampere under an electrical pressure of 1 volt. One watt equals 1/746 horsepower or 1 joule per second. It is the product of voltage and amperage (current). When an object’s velocity is held constant at one meter per second against a constant opposing force of one newton, the rate at which work is one Watt. The word named after the Scottish inventor James Watt.

Energy measurement

It is a measurement term of energy, replacing horsepower kinetic energy, One horsepower is equally moving 250 kilogram vertical per second. one horsepower = 745,69 watt.

Watt produced by professional road bicyclists

In sports Watt is commonly used in cycling to measure the performance of the competitors when climbing in the classic stages (such as Col de Restefound 2802 (moh), Col d’Iseran 2764 (moh)) in Tour de France and Giro Italy ( such as Mortirolo 1854 (moh), Passo dello Stelvio 2758 (moh)). The measurement starts at the bottom of the stage and stops when they were passing the final highest point of the stage. Since these classic stages repeated yearly, it is possible to find out if there are low or high use of performing substances. The Watt was significantly higher in the years of Lance Amstrong, Jan Ullrich, Richard Virenque and Marco Patani “The Pirate” he has fastest ” time trial ” on several classic mountain stages and the last cyclist to win the Giro and the Tour in the same year. Only seven have repeated this in bike history.
