Standing Cycling
Standing cycling or cycling out of the saddle is a form of cycling in which the rider stands up while applying force to the pedals. __NOTOC__ Muscle activation One reason for cycling standing up is to vary the muscles used and avoid fatigue. Efficiency and power output Standing cycling is less efficient especially at lower intensities. One study found that both positions have equal time to exhaustion at 86 V̇O₂ max, while standing up had higher time to exhaustion above 94 percent V̇O₂ max. A 2018 study in elite male cyclists found that standing did not affect energy cost but increased mechanical cost including rolling resistance power, rolling resistance coefficient, and lateral sways, resulting in an overall 4.3 percent increase in power needed to maintain the same speed. A 2017 study found that people spontaneously stand up when cycling to minimize muscular effort. Cycling standing up allows for greater power output in the short run because of the application of body we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cycling
Cycling, also, when on a two-wheeled bicycle, called bicycling or biking, is the use of cycles for transport, recreation, exercise or sport. People engaged in cycling are referred to as "cyclists", "bicyclists", or "bikers". Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs). Bicycles were introduced in the 19th century and now number approximately one billion worldwide. They are the principal means of transportation in many parts of the world, especially in densely populated European cities. Cycling is widely regarded as an effective and efficient mode of transportation optimal for short to moderate distances. Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time To Exhaustion
Time is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future. It is a component quantity of various measurements used to sequence events, to compare the duration of events or the intervals between them, and to quantify rates of change of quantities in material reality or in the conscious experience. Time is often referred to as a fourth dimension, along with three spatial dimensions. Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without circularity has consistently eluded scholars. Nevertheless, diverse fields such as business, industry, sports, the sciences, and the performing arts all incorporate some notion of time into their respective measuring systems. 108 pages. Time in physics is operationally defined as "what a clock reads". The physical nature of time is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VO2 Max
VO2 max (also maximal oxygen consumption, maximal oxygen uptake or maximal aerobic capacity) is the maximum rate of oxygen consumption attainable during physical exertion. The name is derived from three abbreviations: "V̇" for volume (the dot appears over the V to indicate "per unit of time"), "O2" for oxygen, and "max" for maximum. A similar measure is VO2 peak (peak oxygen consumption), which is the measurable value from a session of physical exercise, be it incremental or otherwise. It could match or underestimate the actual VO2 max. Confusion between the values in older and popular fitness literature is common. The measurement of V̇O2 max in the laboratory provides a quantitative value of endurance fitness for comparison of individual training effects and between people in endurance training. Maximal oxygen consumption reflects cardiorespiratory fitness and endurance capacity in exercise performance. Elite athletes, such as competitive distance runners, racing cyclists or ...

Power (physics)
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called ''activity''. Power is a scalar quantity. Power is related to other quantities; for example, the power involved in moving a ground vehicle is the product of the aerodynamic drag plus traction force on the wheels, and the velocity of the vehicle. The output power of a motor is the product of the torque that the motor generates and the angular velocity of its output shaft. Likewise, the power dissipated in an electrical element of a circuit is the product of the current flowing through the element and of the voltage across the element. Definition Power is the rate with respect to time at which work is done; it is the time derivative of work: P =\frac where is power, is work, and is time. If a constant force F is applied throughout a distance x, the wor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberto Contador
Alberto Contador Velasco (; born 6 December 1982) is a Spanish former professional cyclist. He is one of the most successful riders of his era, winning the Tour de France twice ( 2007, 2009), the Giro d'Italia twice (2008, 2015), and the Vuelta a España three times (2008, 2012, 2014). He is one of only seven riders to have won all three Grand Tours of cycling, and one of only two riders to have won all three more than once. He has also won the Vélo d'Or a record 4 times. He was regarded as the natural successor of Lance Armstrong and won the 2007 Tour de France with the team. During his time at the Astana team, he won the 2008 Giro d'Italia, the 2008 Vuelta a España and the 2009 Tour de France. Between 2007 and 2011 he won six consecutive Grand Tours that he entered. This included winning the 2010 Tour de France with Astana, although it later emerged that he had tested positive for clenbuterol during the race. After a long battle in court, he was suspended by the Court of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crankset
The crankset (in the US) or chainset (in the UK), is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called ''chainrings'' or ''chainwheels'' attached to the '' cranks'', ''arms'', or ''crankarms'' to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain. Parts Cranks The two ''cranks'', one on each side and usually mounted 180° apart, connect the bottom bracket axle to the pedals. Lengths Bicycle cranks can vary in length to accommodate different sized riders and different types of cycling. Crank length is measured from the center of the pedal spindle to the center of the bottom bracket spindle or axle. The larger bicycle component manufacturers typically offer cr ...
