Ergometer refers to an instrument for measuring work.
In the psychology context, an ergometer is a device used to measure work performed during physical exercise. It can measure the energy output of an individual during exercise, and is often used to assess cardiovascular fitness, muscular strength, and endurance.
Examples of ergometers include:
-
Treadmill ergometers: These are used to simulate walking, jogging or running by adjusting the speed and incline of the treadmill.
-
Cycle ergometers: These are used to measure power output of the legs during cycling exercise. They can be upright or recumbent, and resistance can be adjusted to mimic hills or flat terrain.
-
Rowing ergometers: These are used to simulate rowing on water and measure power output during the rowing motion.
-
Arm ergometers: These measure power output of the upper body and arms, often used for individuals with lower body injuries or disabilities.
Ergometers are widely used in clinical settings, research studies, and athletic training to measure physical fitness, monitor progress, and identify areas for improvement.
