Association between Parameters Related to Oxidative Stress and Trace Minerals in Athletes

The aim of this study was to determine the possible correlations between essential and toxic trace elements of plasma with several anthropometric and body composition parameters and performance in endurance runners. Sixty-five high-level middle and long-distance runners (21 ± 3 years; 1.77 ± 0.05 m; 64.97 ± 7.36 kg; VO2 max. 67.55 ± 4.11 mL/min/kg) participated in the present study. Abdominal, subscapular, iliac crest, triceps, front thigh and medial calf skinfold thicknesses and an incremental test until exhaustion were recorded. Body, fat, muscle and bone mass were estimated. Plasma trace elements were analyzed with inductively coupled plasma mass spectrometry (ICP-MS). Correlations and simple linear regression were used to assess the relationship between trace elements and several variables. Different skinfolds, fat mass, muscle mass and bone mass correlated positively and negatively with trace elements such as copper, manganese, selenium, vanadium, zinc, lithium, rubidium, strontium, arsenic, beryllium and lead. Lithium was related with performance. In conclusion, endurance training causes changes in the body concentrations of several trace elements that trigger modifications in body composition that may be interesting, if confirmed in the future, for the control of metabolic diseases such as obesity.

“…In addition, a meta-analysis evaluating randomized controlled trials (RCTs) deduced significant improvements in several oxidative stress parameters including blood MDA and glutathione after adherence to the Dietary Approaches to Stop Hypertension HDP, compared to the control [ 8 ]. On the contrary, while the intake of dietary antioxidants such as vitamin E and carotenoids display inverse associations with oxidative stress [ 9 , 10 ], inconsistent results were observed from clinical trials which intervened with antioxidant-rich foods or antioxidant supplementations [ 1 , 8 , 11 , 12 ]. This may be attributed to reasons such as functional concentration limits, poor bioavailability and the lack of antioxidant synergy in single antioxidant clinical trials [ 8 , 11 , 12 , 13 ].…”

Incorporating zeaxanthin-rich wolfberry (Lycium barbarum) into a healthy dietary pattern may augment its antioxidant potential. The present 16-week, parallel design randomized controlled trial aimed to investigate the impact of adhering to a healthy dietary pattern, either with or without whole dried wolfberry (15 g/d) on oxidative stress status (plasma malondialdehyde and 8-iso-prostaglandin F2α) in middle-aged and older adults. Changes to carotenoids status (plasma and skin carotenoids) and body composition were further evaluated to explore potential mechanisms which underlie the antioxidant properties of wolfberry. Plasma 8-iso-prostaglandin F2α, plasma zeaxanthin and skin carotenoids status were significantly raised in the wolfberry consuming group (n = 22; p < 0.05) compared to the control group which showed no changes (n = 18). Likewise in the wolfberry group only, inverse association was observed between the change values of plasma zeaxanthin and plasma 8-iso-prostaglandin F2α (−0.21 (−0.43, 0.00) ng/µmol, regression coefficient (95% CI); p = 0.05). Wolfberry consumption with a healthy dietary pattern may serve as a dietary strategy to attenuate lipid peroxidation among middle-aged and older adults who are at a heightened risk of oxidative stress induced age-related disorders. The antioxidant properties of wolfberry may be attributed to its rich zeaxanthin content.

Background and Aim: Arsenic exposure to the body through the oral, dermal, and inhalation routes have a detrimental impact on health, including women’s reproductive health. However, the effect of arsenic exposure through the vulva of women is unclear. The present study therefore examined the effects of long-term arsenic exposure of vulva on uterus inflammation mediated by oxidative stress and inflammatory mechanism. Materials and Methods: Female Rattus norvegicus L was used as the animal model and the arsenic were exposed through vulvar immersion. The arsenic solution was made into four concentrations while the duration of exposure was made in four-time combinations. Uterus inflammation was assessed through histopathological observation of uterus tissue through hematoxylin and eosin (H&E) staining. Oxidative stress was assessed using malondialdehyde (MDA), superoxide dismutase (SOD), and hydrogen peroxide (H2O2); while inflammatory profile was assessed by measuring using tumor necrosis factor α (TNFα). Results: Our data suggested that inflammation could occur at the permissible quality standard concentrations when arsenic was exposed for more than two weeks. At higher concentrations and a longer exposure time, arsenic exposure could lead to chronic inflammation. Arsenic exposure was able to increase the levels of MDA and H2O2 and reduced the SOD suggesting stress oxidative of the organ. Arsenic also could increase the level of TNFα at any concentration after 6 and 8 weeks of exposure suggesting the inflammation process in the uterus. Conclusion: Continuous exposure of vulva with arsenic could induce oxidative stress and chronic inflammation of the uterus. Further study to investigate this finding in human is critical as basic to propose health campaign program to the community in the high arsenic regions.
