Spinning (cycling)

From Academic Kids

de:Spinning Spinning is a form of exercise that involves using a stationary bicycle in a classroom setting. The spin-class concept was created in the 1980s by Jonathan Goldberg ("Johnny G"). It involves a combination of physical and mental ability, requiring you to use your imagination in each class as the scenery never changes. Participants set goals based around their heart rate, which can be measured by hand or using a heart rate monitor.

It is also known as "indoor cycling" or "studio cycling." In the United States, the name "Spinning" is a trademark owned by Jonathan Goldberg. Only instructors and facilities authorized by Goldberg's company, Madd Dogg Athletics, can use the name "Spinning" in the names of their classes. Nevertheless, "spinning" is commonly used to refer to all classes of this kind.

A typical class involves a single instructor at the front of the class who leads the participants in a number of different types of cycling. The routines are designed to emulate terrain and situations encountered in actual bicycle rides, including hill climbs, sprints and interval training. The instructor uses music and enthusiastic coaching to motivate the students to work hard.

Spinning classes generally use specialized stationary bicycles. Features include a mechanical device to modify the difficulty of pedalling, specially-shaped handlebars, and multiple adjustment points to fit the bicycle to a range of riders. The pedals are equipped with toe straps to hold the foot to the pedal, enabling powerful upstrokes. They may also have cleats for use with specialty bicycling shoes. These bicycles do not have the electronic features found on some models of stationary bicycles.

The difficulty of the spinning workout is modulated in three ways:

  1. by varying the resistance on a flywheel attached to the pedals. The resistance is controlled by a knob, wheel or lever that the rider operates, causing the flywheel brake (a common bicycle brake, a friction wheel, a magnetic eddy-current brake, a viscoelastic fluid brake, or a strap running around the flywheel) to tighten. Tightening the brake makes pedalling more difficult while loosening it makes pedalling easier. On most bikes, the brake can be completely loosened, leaving no resistance to pedalling except the inertia of the flywheel; or it can be tightened to a point that the rider can no longer generate enough force to turn the flywheel. Usually, riders who can not tolerate the resistances called out by the instructor are encouraged to ride at a level at which they feel comfortable yet challenged.
  2. by changing the cadence (the speed at which the pedals turn). Pedalling faster against high resistance expends more energy than pedalling slowly against low resistance.
  3. by sitting or standing in various positions:
  • forward; hands at the frontmost part of the handlebars
  • middle; hands between the front and rear of the handlebars
  • rear; hands at the rearmost part of the handlebars (the usual position when sitting)
  • hovering; standing with all movement in the upper body and hips stopped and only the legs in motion
Each of these positions works the muscles in slightly different ways. Proper form for standing while pedalling requires the body to be more upright and the back of the legs touching or enveloping the point of the saddle, with the center of gravity directly over the crank.

A spin class is usually conducted to music. Riders may synchronize their pedalling to be in time with the rhythm of the music, thus providing and external stimulus to encourage a certain tempo. Often, the music chosen by the instructor is dance music or rock music set to a dance beat (i.e. 4/4 time), but not necessarily. This tends to help motivate participants to work harder than they might otherwise. While the music provides a tempo cue, the cadence does not need to be a multiple of the beat in order for the rider to feel in rhythm; the music therefore helps a rider maintain any constant cadence, not just a cadence that matches the beat.

It is recommended when riding in a spin class to bring plenty of water. Spinning is very energetic and causes a lot of sweating, and a person who is near dehydration can easily be dehydrated by the end of an hour of hard riding.

Spinning as a bicycling technique

Spinning on a mobile bicycle refers to the technique of using a range of gears to maintain a constant rapid cadence of 80-100 rpm or more. This technique is recommended to improve bicycle control, aerobic fitness and endurance. Lance Armstrong notably uses this technique even on steep climbs.
