“…Considering this recommendation, the women's total carbohydrate intake was much lower than the recommended (54%±5.1 p<0.05). Other studies have also reported insufficient carbohydrate intake by female athletes, ranging from 48 to 55% of the total energy requirement 5,6,21 . The recommended carbohydrate intake for all athletes is 6 to 10 g/kg/d 7 to maintain glycogen synthesis and sufficient muscle and hepatic energy reserves.…”

Nutritional intake and overall diet quality of female soccer players before the competition period

Objective: To assess the dietary intake and overall diet quality of female soccer players before the competitive games. Methods: This descriptive and cross-sectional study included 21 women aged 20.8±4.5 years from a professional soccer team. Their nutritional status and dietary adequacy during the training period, before competition season, were assessed. Dietary intake was assessed by three 24-hour recalls, one food frequency questionnaire, and the Healthy Eating Index, an overall diet quality index based on food group intake. Results: The athletes have shown proper nutritional status, but a diet deficient in energy due largely to low carbohydrate intake. On the other hand, the intakes of protein, fatty acids, and sodium were above the recommended intakes, even for athletes. Diet quality assessment by the Healthy Eating Index - 2010 resulted in a mean score of 54.6 points of a maximum of 100, indicating a need of improving the overall diet quality. Conclusion: The study found that the dietary patterns of female football players were both quantitatively and qualitatively inappropriate. A nutritional intervention is indicated to improve diet quality, with the inclusion of various foods, such as whole grains, fruits, vegetables, dairy products, and better protein quality, along with a reduction in saturated fats, sodium, and added sugar.

“…It is known that the lipid hydroperoxides are unstable with the presence of metal ions and it is decomposed to a variety of reaction products, whereas conjugated dienes take up O 2 and form peroxyl radicals or lipid hydroperoxides (Jenkins, 2000). Nonetheless, one limitation of the present study could be related with content of antioxidant nutrition (Gravina et al, 2012), which could not be fully controlled. This may explain the significantly higher levels of thiobarbituric acid reactive species for SMW with respect to placebo at the basal period.…”

“…First, the basal plasma thiobarbituric acid reactive species levels were significant different between both groups, suggesting that some variables were not full controlled such as the antioxidant nutrition content (Gravina et al, 2012). Second, in spite of main antioxidant enzymes were measured at the present study, other antioxidant markers, such as total antioxidant capacity or plasma/erythrocyte glutathione levels, were not measured to have a whole understanding of SMW antioxidant effect.…”

To investigate the effects of sulphurous mineral water (SMW) after a hydroponic treatment on muscle damage, antioxidant activity and peripheral blood changes induced by submaximal exercise. Thirty well-trained male triathletes were supplemented with SMW or placebo: 3 weeks of placebo, 30 days of wash out and 3 weeks of SMW. After both periods, participants ran for 2 h at 70% maximal aerobic speed. Antioxidant enzymes, lipid peroxidation, antioxidant capacity and blood cell markers were compared between placebo and SMW at pre-exercise (T0), immediately post-exercise (T1), 24 h post-exercise (T2) and 48 h post-exercise (T3). Total thiols decreased until T3 vs. T0 for both placebo and SMW; transient red blood cells, haemoglobin and haematocrit increased were shown at T1 vs. T0 and for leucocytes until T2 vs. T0, only for placebo group. Total thiols increased significantly in SMW vs. placebo at T0; Thiobarbituric acid reactive species was significantly higher at T0, T1, T2 and T3; catalase increased significantly at T1; creatine phosphokinase decreased significantly at T1, T2 and T3, although no significant differences were found at T0. Furthermore, red blood cells, haemoglobin and haematocrit were significantly higher and leucocytes were significantly lower at T0 and T1 in SMW group vs. placebo group. This study suggests that three weeks of SMW supplementation may protect from exercise-induced muscle damage.

“…Also, some earlier studies have reported the beneficial effects of n-3 and n-6 polyunsaturated fatty acids on oxidative stress and antioxidant capacity (20,21). However, some other researchers have revealed that n-3 FA available in fish oil not only could not significantly reduce antioxidant parameters in cardiomyocytes, but also enhanced MDA plasma concentrations in the athletes (22,23).…”

Objectives: Many researches have focused on reducing the deleterious effects of oxidative stress in biological systems. The present study investigated the effect of palmitoleic acid on the oxidative stress parameters induced by palmitic acid on cardiomyocytes. Methods:Rat cardiomyocytes were treated with 0.5 mM palmitate, palmitoleate, and palmitate + palmitoleate, or remained as control. Total antioxidant capacity (TAC) and Malondialdehyde (MDA) values were measured in both the cells and the media at 24h and 48h intervals.Results: While cellular TAC values decreased in the palmitic acid group compared to the control group (24%) at 48h time point (P < 0.001), the palmitoleic acid group showed 45% and 19% increases (P ≤ 0.001); Co-incubation of palmitoleate and palmitate indicated 44% (P = 0.001) and 11% (P = 0.02) increases compared to the control group at 24h and 48h time points, respectively. Co-incubation of palmitoleate and palmitate tended to decrease the MDA values in the cells and media compared to the palmitate group at 24h time point (P = 0.09). Conclusions:In conclusion, the harmful effects of the oxidative stress induced by palmitate would be diminished by palmitoleate in the rat cardiomyocytes.
