Abstract
The aim of present research was to study the effects of Amaranth oil (AmO) supplementation on aerobic metabolism and heart rate variability (HRV) in type 2 diabetes mellitus patients and in athletes. Several parameters of aerobic metabolism and HRV were assessed. Supplementation with AmO caused mild pro-oxidant activity resulting in improved uptake of oxidative destruction products and modulation of catalase and SOD activity with subsequent development of an antioxidant effect. These findings were very distinct in athletes but less pronounced in diabetics. Redistribution of haemoglobin ligands in athletes indicates involvement of haemoproteins in free radical reactions during AmO supplementation. Improvement in HRV by daily consumption of AmO as observed in both study groups suggested increased production of endogenous oxygen and enhancement of the cardio-respiratory function. The advantage of activation of aerobic metabolism in OS-related disorders resulting in improved self-organization of the living system and hormetic reaction mechanisms are discussed.
Acknowledgement
This article would not appear without the initiative and keen interest of the late Professor Janos Feher, who supported our scientific concept of oxidative stress correction and made us think about its implication in metabolic syndrome. We also have to mention an important role of our teacher Professor Mykhaylo Tymochko, who left us valuable scientific acquirement in the field of free radical and oxygen homeostasis and died too early under tragic circumstances. This research is dedicated to them. The study was supported by COST B35 Action.
