Key result
An 8-week intense aerobic training program in adults over 70 increased peak cycle resistance by 25% and oxygen consumption by 18%, without changing heart rate variability.

May improve exercise capacity in adults over 70; hypothesis-generating for autonomic effects and needs RCT confirmation.
Does an intense 8-week aerobic training program improve cardiovascular responses and heart rate variability in adults over 70 years old?
An 8-week aerobic training program in older adults improves exercise capacity and peripheral gas exchange without altering cardiac autonomic modulation as measured by heart rate variability.
Perini et al. (2002) studied this question. Intense aerobic training program vs. Pre-training baseline was evaluated on Cardiovascular responses at rest and during exercise, including heart rate variability. An 8-week intense aerobic training program in adults over 70 increased peak cycle resistance by 25% and oxygen consumption by 18%, without changing heart rate variability.
