Selected physical performance and heart rate (HR) data from the Polar Team Pro system.
| Physical Performance Parameters | |
|---|---|
| Total distance (m) | Total distance during the training session, particularly during the Dance choreographies and the fitness Dance parts (in meters). |
| Distance/min (m/min) | Average distance per minute during the training session, particularly during the Dance choreographies and the fitness Dance parts (in meters). |
| Maximum speed (km/h) | Maximum speed during the training session. Particularly during the Dance choreographies and the fitness Dance parts (kilometre/hour) |
| Average speed (km/h) | Average speed during the training session, particularly during the Dance choreographies and the fitness Dance parts (kilometre/hour) |
| Physiological parameters | |
| Minimum Heart rate (HRmin) | Resting HR before the training session calculated as (bpm) and as % of the HR max (% HR max). A recording duration of 3 min, prior to test sessions, in a standing position was used. In the absence of pathologies or use of pharmaceuticals, a low resting HR indicates, in general, a healthy heart. |
| Maximal heart rate (HRmax) | Maximal HR during the training session calculated as “bpm” and as % of the HR max (% HR max). |
| Average heart rate (HRavg) | Average HR during the training session calculated as “bpm” and as % of the HR max (% HR max). |
| Average RR interval (Avg RR) | Average beat-to-beat interval during the training session (ms). Increase over time means that fitness is improving. |
| Maximum RR interval (Max RR) | Maximum time between successive heartbeats (beat-to-beat interval) recorded during the training session (milliseconds). |
| HRV (RMSSD) | The root mean square of successive differences between normal heartbeats (RMSSD) is obtained by first calculating each successive time difference between heartbeats in milliseconds (ms). Each of the values is then squared and the result is averaged before the square root of the total is obtained. The RMSSD reflects the beat-to-beat variance in HR and reflects short-term HR variability HRV [62]. High resting-state HRV is related to improved health and indicates that the heart is functioning well, and that the autonomic nervous system is adapting to the demands placed on it. https://www.polar.com/blog/heart-rate-variability-and-orthostatic-test-lets-talk-polar/ (accessed on 20 April 2021) |
| Time in HR zone 1 | HR zones are a way to monitor the training intensity. There are five HR zones based on the intensity of training with regard to the maximum heart rate. The % of HR max in each zone are as following: Zone 1: 50–60%, Zone 2: 60–70%, Zone 3: 70–80%, Zone 4: 80–90%, Zone 5: 90–100%. (https://www.polar.com/blog/running-heart-rate-zones-basics/). In the present paper, the time in each HR zone was calculated as % of the whole session time (e.g., spending 20 min in zone 1 during a 90 min session → Time in HR zone 1 = 22.22%) |

| Time in HR zone 3 | |

| Training Load | |
| Training load score | Training Load includes textual feedback on the strenuousness of a single training session. It is based on the intensity and duration of a training session, with the intensity of a session measured using HR, and the calculation is further affected by personal information such as age, sex, weight, VO2max, and training history. As a participant’s fitness improves, the same training session creates less training load. https://support.polar.com/en/support/the_what_and_how_of_training_load (accessed on 20 April 2021) |
