Polar CS200 CAD Cycling Computer Heart Rate Monitor

For goal-oriented cyclists who want more out of their training and performance. Measures heart rate combined with current, average and maximum speed and determines daily personal heart rate target zones for optimal training. It connects to your online training diary at polarpersonaltrainer.com using SonicLink (requires PC microphone and sound card). It includes both CS Speed and CS Cadence Sensors so you can measure your pedaling rate as revolutions per minute to compare the effectiveness of your ride against previous rides, and measures your current/average/maximum speeds and tracks your average speed.

X X X X X X X X X X Cadence - current, average, maximum Your cycling cadence stands for your pedaling rate in revolutions per minute (rpm). Cadence is the central factor in improving cycling performance. A higher cadence reduces the force needed for each pedal stroke, and thus improves overall performance. Running cadence measures how many times your either right or left foot hits the ground in one minute. Running cadence is measured as steps per minute. With this feature you can sharpen your cadence and make your ground contact time shorter. This will help you to find a balance between leg power and leg speed. with Opt. Cadence Sensor with Opt.

X X X X X X   X X   Cycling limits This feature is useful for maintaining a certain level of intensity in your training. You can set upper and lower limits for heart rate, cadence, speed or power output. The training computer gives audible and visual alarms if your cycling rate goes out of the preset range.           X   X X X Incline measurement Incline measurement tells you the uphill or downhill inclination in numerical form, helping you to adjust cycling effort accordingly. The feature shows you the uphill/downhill steepness in percentages and grades.           X X X X X Pedaling index Pedaling index is the ratio between the minimum and maximum forces of a single pedaling cycle. A pedaling cycle begins when a magnet on the crank passes a relay on the circuit board and ends when the magnet passes the relay again. The resulting ratio is averaged from the most recent pedaling cycles. Pedaling index helps optimize pedaling technique by measuring the ‘roundness’ of force distribution, or how evenly the power is produced – the higher the pedaling index percentage, the better.               with Opt. Cadence Sensor with Opt. Cadence Sensor   Cycling Efficiency index Cycling efficiency is your energy expenditure converted into the power that propels the bike forward. Cycling efficiency measurement starts as soon as heart rate rises above 100 bpm and the training session has lasted for more than one minute. If the heart rate drops below 100 bpm during the session, the measurement of cycling efficiency value is stopped until your heart rate rises above 100 bpm again. Improvement in cycling efficiency indicates improved performance economy.               with Opt. Power Output with Power Output incl.   Left/Right balance               with Opt.

Set the distance you are going to ride, and your cycling computer calculates the estimated time of arrival based on your cycling speed. n the cycling settings you can set RideDist (riding distance). You can set the distance you are going to ride and the cycling computer will estimate your arrival time to the destination according to your riding speed. Estimated time of arrival works during your exercise recording and it can be seen on the upper row of the display.             X       Speed/Pace - current, average, maximum Speed (km/h or mi/h) is measured with GPS, footpod, stride sensor or cycling speed sensor.

A longer interval gives you more recording time, while a shorter interval allows you to record more detailed data. A shorter recording rate uses the memory of the training computer up more rapidly, but enables more accurate data analysis using Polar software.           1s, 5s, 15s, 60s   1s, 5s, 15s, 60s 1s, 5s, 15s, 60s   R-R recording R-R recording rate saves heartbeat intervals, that is, intervals between successive heartbeats.
