Abstract

Purpose: To determine the sensitivity of the frequency meter Polar ® RS800CX in postural maneuver from the heart rate (HR) and HR variability (HRV) param - eters. Method: Young (n=20) healthy men had registered HR and RR intervals (RRi) measurements in the time domain (RRi, RMSSD, pNN50) and frequency (LF, HF and LF.HF-1) using the Polar® RS800CX. Results: Differences were found to supine position (SUP) 5 ‘and SUP10’ vs. standing position (STP) 5 ‘and STP10’ in HR (61.1 ± 1.1 and 61.0 ± 1.3 bpm vs. 79.5 ± 3.9 and 80.8 ± 3.5 bpm), RRi (990.0 ± 19.9 and 994.5 ± 23,2 ms vs. 787.4 ± 34.0 ms and 768.6 ± 30.1 ms), rMSSD (70.5 ± 8.4 and 71.1 ± 8.5 ms vs. 32.2 ± 3.4 and 30.7 ± 3.7 ms), pNN50 (41.1 ± 6 0 and 46.3 ± 5.3% vs. 15.4 ± 2.5 and 14.3 ± 2.6%), LF (52.3 ± 6.4 and 55.4 ± 6.5 n.u. vs. 82.0 ± 4.2 and 80.7 ± 4.8 n.u), HF (47.7 ± 6.4 and 44.6 ± 6.5 n.u. vs. 18.0 ± 4.2 and 19.3 ± 4.8 n.u.) and LF.HF -1 (2.9 ± 0.8 and 3.1 ± 0.8 vs. 14.1 ± 2.9 and 14.3 ± 3.1). Conclusion: The frequency meter RS800CX Polar ® appeared sensitive to variations in body posture.
