Key result
A 3-month exercise training program in patients with POTS increased peak oxygen uptake by 11% (P<0.001) due to increased peak stroke volume (P=0.021).

Does a 3-month exercise training programme improve cardiovascular responses during exercise in patients with POTS?
Absolute Event Rate: 26.1% vs 36.3%
p-value: p=<0.001
A 3-month exercise training program in patients with POTS improves physical fitness and cardiovascular responses during exercise, primarily by increasing stroke volume and lowering heart rate at a given oxygen uptake.
Shibata et al. (2012) studied Postural orthostatic tachycardia syndrome (POTS) (n=29). Exercise training programme vs. Healthy sedentary controls and baseline (pre-training) was evaluated on Peak oxygen uptake (VO2peak) at baseline (POTS vs controls) (p=<0.001). A 3-month exercise training program in patients with POTS increased peak oxygen uptake by 11% (P<0.001) due to increased peak stroke volume (P=0.021).
