Does Taichiquan acutely improve heart rate variability in healthy young and elderly men?
Taichiquan acutely increases heart rate variability in healthy young and older men, suggesting a positive short-term effect on autonomic function.
May indicate acute autonomic effects of Taichiquan in healthy men; hypothesis-generating and requires controlled trials before clinical consideration.
A group of 15 elderly men and 14 young male students of physical education made twice a series of Taichiquan (TCQ) practices. Their electrocardiograms were recorded on tape-recorder and heart rates and heart rate variability (HRV) were calculated from digitized data. Here we report the results of recordings in supine positions before and after the first and second series of TCQ. Intervals between heart beats (RRIs) and their standard deviation (SDNN) increased in older men from recordings before the exercise to postexercise. In young subjects the SDNN and total variance (TV) of RRIs increased. HRV increases immediately after TCQ-exercise in young and old male healthy subjects. Whether these practices have permanent effects and effects in patients need controlled and prospective studies.

Väänänen et al. (2002) conducted an observational in Healthy subjects (n=29). Taichiquan (TCQ) practices vs. Pre-exercise baseline was evaluated on Heart rate variability (HRV), RR intervals (RRIs), and SDNN. Taichiquan exercise acutely increased heart rate variability, including RR intervals and SDNN, in both young and elderly healthy male subjects immediately post-exercise.
