A time trialist is a road bicycle racer who can maintain high speeds for long periods of time, to maximize performance during individual or team time trials. The term ''cronoman'', or ''chronoman'', is also used to refer to a time trialist; this term is often used by Davide Cassani in his commentaries. In a traditional individual time trial, riders set off alone (not in a group or peloton) at intervals, typically anything from one to five minutes, and try to complete the course in as short a time as possible. In order to maximize the overall speed a time trialist must be able to maintain a steady effort throughout the event, of which the best measure is believed to be the rider's power at lactate threshold (LT) or aerobic threshold (AT). The best time trialists (such as Miguel Indurain, David Millar, Ellen van Dijk, Tony Martin and Fabian Cancellara), are believed to have very high power output at LT/AT, which they can then maintain for the duration of the time trials. To be a successful time trialist, a cyclist must have exceptional aerodynamic posture and be able to take in plenty of oxygen.〔 Aerodynamic performance can also be improved by riders using 'skin suits', overshoes and streamlined helmets. Bike technology is also important in time trials. By using aerodynamic components, a bicycle can be designed to minimize its drag coefficient, allowing a rider to drop his or her time by minutes during a long course. Time trials may also form individual stages of stage races. By incorporating time trial specialists into a cycling team, the team can lower its aggregate time dramatically. In relatively flat mass start stages and races, time trialists often work as domestiques for their team leaders, or participate in breakaways. ==Famous time trial specialists== Some successful time trialists: ;Men * Jacques Anquetil * Maurice Archambaud * Chris Boardman * Fabian Cancellara * Viatcheslav Ekimov * Laurent Fignon * Daniel Gisiger * Bernard Hinault * Serhiy Honchar * Miguel Indurain * Knut Knudsen * Greg LeMond * Thierry Marie * Tony Martin * Eddy Merckx * David Millar * Francesco Moser * Lech Piasecki * Ole Ritter * Michael Rogers * Tony Rominger * Didi Thurau * Jan Ullrich * Herman Van Springel * Bradley Wiggins * Alex Dowsett * Rohan Dennis ;Women * Kristin Armstrong * Lisa Brennauer * Beryl Burton * Ellen van Dijk * Jeannie Longo 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「time trialist」の詳細全文を読む スポンサード リンク
