On the Significance of Magnesium in Extreme Physical Stress
Authors: Golf S.W.; Bender S.; Grüttner J.1
Source: Cardiovascular Drugs and Therapy, Volume 12, Number 2, May 1998 , pp. 197-202(6)
Abstract:
In a double-blind randomized study, 23 competitive triathletes competing in an event consisting of a 500-meter swim, a 20-km bicycle race, and a 5-km run were studied after 4-week supplementation with placebo or 17 mmol/d Mg orotate. The tests were carried out without a break. Blood was collected before and after the test, and between the different events for assaying energy stress and membrane metabolism. Swimming, cycling, and running times decreased in the Mg-orotate group compared with the controls. Serum glucose concentration increased 87% during the test in the control group and 118% in the Mg-orotate group, while serum insulin increased 39% in the controls and decreased 65% in the Mg-orotate group. Venous _2 partial pressure increased 126% during the test in the controls and increased 208% in the Mg-orotate group. Venous _2 partial pressure after the bicycle race decreased 66% (significantly) in the Mg-orotate group compared with 74% in the controls. Blood proton concentration decreased to 90% in the Mg-orotate group (significantly) compared with 98% in the controls. Blood leukocyte count increased from 5.92/nL to 11.0/nL in the controls and from 5.81/nL to 9.10/nL in the Mg-orotate group, a significant difference. Serum cortisol was lower in the Mg-orotate group before and after the test compared with the controls. CK catalytic concentration after the test was elevated 140% in the controls compared with 122% Mg-orotate group. The stress-induced modifications of energy and hormone metabolism described in this study indicate altered glucose utilization after Mg-orotate supplementation and a reduced stress response without affecting competitive potential.

Effects of Magnesium Orotate on Exercise Tolerance in Patients with Coronary Heart Disease
Authors: Geiss K.-R.; Stergiou N.; Jester; Neuenfeld H.U.; Jester H.-G.1
Abstract:
In a pilot study at 14 patients with coronary heart disease (CHD) and left-ventricular dysfunction (left ventricular enddiastolic volume [LVEDV] 100 ml), who actively participated in an ambulatory cardiac sports group, left ventricular endsystolic volume (LVESV), LVEDV and duration of exercise were analyzed by echocardiographic and ergometric tests. An initial workup was followed by a 4 week double blind treatment phase, in which magnesium orotate 3 x 1 g or placebo was given additionally to medication taken prior to the study. At the end of this phase a concluding workup was performed. Magnesium orotate decreased significantly (p = 0,016) LVESV, increased significantly (p = 0,035) EF, decreased in tendency (p = 0,054) LVEDV and increased significantly (p = 0,011) exercise duration. The study gives references to favourable effects of oral magnesium orotate to left ventricular function and exercise tolerance in patients with CHD.
wskazuja ze cos kolo 3 g - oczywiscie to NIE sa zawodowi sportowcy
Slawek wspominal ze to 'antyczny '
suplement - moze kojarzyc bedzi praktyczne dawki ...
