S1 Foot Pod two shoes two shoes with Opt. s3 two shoes with Opt. s3 Three shoes two shoes with Opt. s3 Average stride length Stride length is the average length of one step, that is, the distance between your right and left foot contacting the ground. Runners adjust stride length to gather speed: stride length increases as speed increases. Yet one of the most common mistakes novice runners make is over-striding. The most efficient stride length is the natural one – the one that feels most comfortable.             with Opt. s3 with Opt. s3 X with Opt. s3 Distance based intervals The Interval Trainer will automatically guide you through the interval training session with the help of preset training phases: warm-up, intervals and cool-down. The interval phase is divided into interval and recovery calculation sections, which alternate continuously throughout your interval phase. The distance based interval ends your interval as you reach the selected distance.             with Opt. CS WIND Speed or G3 X with Opt. CS WIND Speed or G3 X Distance based recovery measurement             with Opt. CS WIND Speed or G3 X with Opt. CS WIND Speed or G3 X Distance Distance (km, mi) can be set and measured in several ways. Training distance tells you the distance traveled during a training session. Trip distance tells you the distance from the latest trip reset. Lap distance tells you the distance of one lap. Total distance is the distance accumulated since the last reset. Odometer tells you the cumulative distance which you cannot reset.   with Opt. S1 or G1 X X X training lap total with Opt.

When you start training, you can select the bike with the correct settings for that particular training session.             with Opt. Cadence or Speed X with Opt. Cadence or Speed with Opt. Cadence or Speed 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 or s3 with Opt. Cadence or s3 X with Opt. Cadence or s3 Cycling limits This feature is useful for maintaining a certain level of intensity in your training.

Depending on the day and time, your physical state may vary, for instance, if you are stressed or tired, or if you are not fully recovered from your latest training session, Polar can determine that information from your heart rate and guide you to your ideal training zone for that moment. X X X X X X X X X X Adjustable recording rate The samples of your heart rate, speed, cycling cadence, power and altitude are stored either in 1, 2, 5, 15 or 60 second intervals. 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         R-R Intervals/Online HR Variability R-R Intervals / Online HR Variability feature measures your heartbeat intervals and reflects autonomic nervous system activity in heart beat regulation. The R-R interval measurement is most useful at rest and at low intensities. Relaxation rate indicates the state of your physical recovery.             X X X X R-R recording R-R recording rate saves heartbeat intervals, that is, intervals between successive heartbeats. This information is also shown as instantaneous heart rate in beats per minute in recorded samples. This enables the analysis of heart rate variability (HRV) using the ProTrainer 5 software with an accuracy of 1 ms.             X X X X Relaxation rate during training This measurement is based on the heart rate variability, which indicates your autonomic nervous system's state. The degree of heart rate variability is highly individual and tends to decrease over time.
