Brief HRV Norms

Healthy Adult Norms

Nunan et al. (2010) reviewed normative data from short-term HRV studies published after the Task Force report (1996). The 44 selected studies meeting their criteria involved 21,438 healthy adult participants. Recall that LFnu and HFnu are normalized values calculated for brief measurements by dividing LF power or HF power by the sum of LF power + HF power.

Elite Athlete Norms

Optimal performance professionals should be interested in the Berkoff et al. (2007) short-term norms from 145 elite track-and-field athletes measured before the 2004 U.S.A. Olympic Trials. The investigators monitored the athletes in the supine position using ECG after up to 5 minutes of rest to stabilize heart rate.
