As a whole, responses to the maneuvers were strictly inside the expected limits indicating a high reproducibility of the tests.

Regarding parasympathetic tests, the 4-s unloaded exercise test was revealing: initial heart rate response was higher after feeding than pre-prandial again only in Hp group (1.40 ± 0.20 vs. 1.33 ± 0.17, p=0.0195).
