We studied the association of physical activity and adherence to the Mediterranean diet, in total antioxidant capacity (TAC). A random sample of 1514 men and 1528 women was selected from Attica region. Physical activity was assessed with a translated version of the validated “International Physical Activity Questionnaire” (iPAQ), and dietary intake through a validated Food Frequency Questionnaire (FFQ). Adherence to the Mediterranean diet was assessed by the MedDietScore that incorporated the inherent characteristics of this diet. TAC was positively correlated with the degree of physical activity (P<.05). TAC was also positively correlated with MedDietScore (r=0.24,P<.001). Stratified analysis by diet status revealed that the most beneficial results were observed to highly active people as compared to inactive, who also followed the Mediterranean diet (288  ±  70 μmol/L,230  ±  50 μmol/L, resp.), after adjusting for various confounders. Increased physical activity and greater adherence to the Mediterranean diet were associated with increased total antioxidant capacity.

Objective.The purpose of the study was to assess total antioxidant capacity (TAC) of blood serum in relation with habitual leisure time physical activity (LTPA) and aerobic capacity in a group of 90 men with coronary heart disease (CHD) aged 34.8–77.0 years and in 90 age-matched peers without CHD.Methods.Two spectrophotometric methods were applied to assess TAC: Ferric Reducing Ability of Serum (TAC-FRAS) and 2.2-diphenyl-1-picryl-hydrazyl (TAC-DPPH) tests. Aerobic capacity was expressed as physical working capacity at 85% of the maximal heart rate (PWC85%HRmax).Results. CHD patients had higher values of TACFRAS (1.37±0.28versus1.27±0.23 mmol FeCl2·L−1;P<0.05) but there were no group differences for TAC-DPPH and for uric acid (UA). Negative correlation was found between LTPA (also when calculated per kg of body mass) and TAC-DPPH in CHD patients. In CHD patients, TAC-FRAS and UA were lower in subjects with higher aerobic capacity expressed asPWC85%HRmax/kg. Those associations were not found in healthy men.Conclusions. We conclude that TAC of blood serum is moderately adversely related to LTPA and aerobic capacity in patients with CHD. UA, as the main determinant of serum TAC, may be partially responsible for those associations.

This study aimed to determine the impact of sesame meal, selenium (Se), and vitamin E (VitE) on goats’ oxidative status. Thirty mid-lactation crossbred goats were divided into five homogeneous groups, and were fed 1 kg of alfalfa hay and 1.2 kg of concentrates daily. The control group (C) received a basal diet. In the concentrates of the treated groups, 10% of the soybean meal was replaced by sesame meal and no extra VitE or Se (SM), or an extra 60 mg of VitE (SME), or 0.1 mg organic Se (SMSe), or their combination (60 mg VitE and 0,1 mg organic Se/kg of concentrate (SMESe). In the plasma of the goats, the dietary treatments did not affect glutathione reductase, glutathione peroxidase, glutathione transferase, catalase, superoxide dismutase activities, malondialdehyde (MDA) content, or the total antioxidant capacity. A reduction and a trend for lower protein carbonyls content was found in goats fed SM (p = 0.03) and SME (p = 0.06) compared to SMESe. In the milk, the lactoperoxidase activity decreased with SMSe and SMESe. A numerical decrease in the total antioxidant capacity and an increase in the MDA content in the milk of the SMESe group compared with the other treated groups was found. In mid-lactation goats, SM improves the oxidative status of both the organism and the milk.

AbstractObjective:To investigate the relationship between different types and levels of physical activity and cardiovascular disease risk factors, including oxidative stress, blood lipids and insulin resistance, in a healthy female population in China.Method:Healthy women (n= 761) aged 35 to 65 years participated in this study. The habitual physical activity was evaluated by self-administered questionnaire (MOSPA). The dietary intakes of nutrients were calculated from 3-day recall records. Anthropometric data of each subject were measured, fasting blood samples were taken, and erythrocytes and serum were prepared for the measurement of erythrocyte superoxide dismutase activity, serum malondialdehyde, total antioxidant capacity, insulin, glucose and lipids (total cholesterol, triglycerides, apolipoprotein AI (apo A) and apolipoprotein B (apo B)) concentrations.Results:Low level of physical activity was related to a lower concentration of serum apo B, and higher energy expenditure from household physical activity had a reverse relationship with serum apo B and triglyceride levels. In the group with moderate occupational energy expenditure, the concentration of serum triglycerides was lower, but that of high-density lipoprotein was higher. Moderate energy expenditure (less than 1700 kcal day−1) from leisure-time physical activity was positively related to total antioxidant capacity and insulin sensitivity. However, heavy occupational physical activity may be not beneficial for the cardiovascular system.Conclusion:This study indicates that leisure-time, moderate occupational and household physical activity levels decreased risk factors for cardiovascular disease.
