Monark cycle ergometer8/9/2023 More importantly for users, the bike comes with aerobic test software for executing and analyzing aerobic tests, along with an adjustable brake system in which the brake force (resistance) can be set or read in kiloponds (KP) or Newtons (N), with a workload range of 0 to 7 KP. This arrangement works as a pendulum balance which measures the difference in pulling power on the two ends of the belt. The two ends of the belt are attached to a revolving drum to which a pendulum is fixed. Braking of the wheel takes place mechanically via a belt that surrounds the rim of the wheel. Since the first Monark bike left the factory a century ago, there have been many changes to the ergometer development. The pendulum balance is easy to calibrate. In addition, braking power can be set, giving a reading of calorie consumption (CAL) and power in watts (WATT). It displays effective output in watts and heart rate using telemetry, pedal-turns per minute (RPM), heart rate in beats per minute (HR), cycling-time in minutes and seconds (TIME), intended cycling speed in km/miles per hour (SPEED) plus distance covered in km/miles (DISTANCE). The successor to the 818E, the Monark 828E Test Ergometer has a new softer design, a completely housed flywheel and strengthened frame. It features a quality digital readout measuring heart rate (by using a chest belt), speed, pedal revolutions, distance, time, calorie consumptions and power in watts. These differences are probably attributable to the mechanical principles which underpin the tests.The Monark 828E pendulum balance ergometer is the world’s most used test cycle for fitness testing at work. The results demonstrate that optimization and correction procedures produce different values of performance. Similarly, RPMopt was less than RPMcorr (111 +/- 1 vs 128 +/- 2 rev min-1 and 101 +/- 1 vs 111 +/- 2 rev min-1 in the males and females, respectively P < 0.001). One of the bouts used a loading equivalent to 7.5% of body weight and for this bout corrected peak power output (PPcorr) and its corresponding pedalling rate (RPMcorr) were calculated. From the inverse linear relationship between applied load and peak pedalling rate, optimized peak power output (PPopt) and the accompanying pedalling rate (RPMopt) were calculated. The loads were selected to produce peak pedalling rates in the range 100-200 rev min-1 and each bout lasted 10 s. After a 5 min warm-up, the subjects performed four bouts of all-out exercise on a Monark 814E cycle ergometer against randomly assigned loads. Nineteen males aged 20.9 +/- 0.4 years and 18 females aged 22.2 +/- 0.7 years (mean +/- S.E.M.), who were fully accustomed to the procedures, participated in a single experimental protocol. The aim of this study was to compare performance in each procedure and so investigate assumptions which underpin the tests. Assessments of maximal intensity exercise which determine peak power output on friction-baked cycle ergometers have fallen into two categories: correction procedures which account for changes in momentum of the ergometer's flywheel and optimization procedures which attempt to satisfy muscle force-velocity relationships.
