“…*Significant differences versus control incubation (0 mg/100 ml PLX), p \ 0.05 Eur J Appl Physiol (2011) 111:2281-22942289 neutrophils observed after the swimming session was probably associated with an immune response to exercise that included neutrophil priming to the oxidative burst, as seen after a football match or a cycling stage Tauler et al 2008b). Diet supplementation with moderate levels of antioxidants such as vitamins E and C or ubiquinone has been shown to reduce plasma oxidative damage induced by intense exercise such as a half-marathon ) or a football match ), but without blocking the cellular adaptation to exercise Tauler et al 2008b). However, diet supplementation with high doses of vitamin C, as much as 1 g/day for 1 week, has been seen to reduce the neutrophil response to the hypoxia/reoxygenation associated with apnea diving (Sureda et al 2004).…”

Our aim was to investigate the effects of diet supplementation with phytoestrogens on sex hormone levels, antioxidant adaptive responses and oxidative damage induced by exercise. Ten female swimmers participated for 26 days in a diet intervention with either a functional beverage rich in vitamins C and E or the same beverage but also supplemented with Lippia citriodora extract (PLX) containing 20 mg/100 ml verbascoside. After the intervention all subjects participated in a swimming session for 30 min maintaining the intensity at about 75-80% of their individual best performance time for a 50-m swim. In lymphocytes, the superoxide dismutase activity increased after exercise, with a higher increase in the PLX group. Swimming increased the erythrocyte activity of glutathione peroxidase and glutathione reductase in the PLX group. Purified glutathione reductase activity increased after an in vitro incubation with PLX. No effects were observed on the lymphocyte levels of malondialdehyde and carbonyls, but exercise increased the percentage of high-damaged lymphocytes 2.8 times in the placebo group and 1.5 times in the PLX group. PLX decreased the levels of 17-β-estradiol and testosterone and increased the levels of the sex hormone binding globulin. In conclusion, supplementation with phytoestrogens enhances the glutathione-dependent enzyme activities in erythrocytes and the superoxide dismutase activity in lymphocytes in response to exercise. PLX also shows direct antioxidant properties, by increasing glutathione reductase enzyme activity in vitro. Supplementation with phytoestrogens also decreases the plasma steroid hormone levels, pointing towards a possible agonistic effect of verbascoside in the hypothalamic regulation of estradiol synthesis.

“…Neutrophils only rose about 32% after 30 min of swimming at 80% of subject's best performance time for a 50 m swim, whereas in other longer, more intense exercise tests the increase in neutrophil counts is much greater Tauler et al 2008b). The rise in circulating Results are expressed as mean ± SEM (n = 5).…”

Purpose: This study examined the effects of exercise-induced fatigue on soccer skills performed throughout simulated match play. Methods: Fifteen academy soccer players completed a soccer match simulation (SMS) including passing, dribbling, and shooting skills. Precision, success rate, and ball speed were determined via video analysis for all skills. Blood samples were obtained before exercise (preexercise), every 15 min during the simulation (15,30, 45, 60, 75, and 90 min), and 10 min into half-time. Results: Preliminary testing confirmed testretest repeatability of performance, physiological, and metabolic responses to 45 min of the SMS. Exercise influenced shooting precision (timing effect: P = .035) and passing speed (timing effect: P = .011), such that shots taken after exercise were 25.5 ± 4.0% less accurate than those taken before exercise and passes in the last 15 min were 7.8 ± 4.3% slower than in the first 15 min. Shot and pass speeds were slower during the second half compared with the first half (shooting: 17.3 ± 0.3 m•s -1 vs 16.6 ± 0.3 m•s -1 , P = 0.012; passing: 13.0 ± 0.5 m•s -1 vs 12.2 ± 0.5 m•s -1 , P = 0.039). Dribbling performance was unaffected by exercise. Blood lactate concentrations were elevated above preexercise values throughout exercise (time of sample effect: P < .001). Conclusions: These findings demonstrate that soccer-specific exercise influenced the quality of performance in gross motor skills, such as passing and shooting. Therefore, interventions to maintain skilled performance during the second half of soccer match play are warranted.

“…Average HR and blood lactate responses were comparable with previously published values for soccer match play, 1 and the proportion of time spent in the relative exercise intensities (HR zones 1-4) also agreed with previously reported values. 29 However, lactate concentrations collected during soccer match play largely represented the pattern of activity in the immediate presampling period, 4 and thus such data should be interpreted with caution. Nevertheless, given that our supplementation regime was similar to published nutritional guidelines on fluid replacement, 30 our findings suggested that current CHO-fluid-replacement strategies do not increase blood glucose concentrations in the second half of soccer match play when the halftime recovery period is passive.…”

Context: The ingestion of carbohydrate (CHO) before and during exercise and at halftime is commonly recommended to soccer players for maintaining blood glucose concentrations throughout match play. However, an exercise-induced rebound glycemic response has been observed in the early stages of the second half of simulated soccer-specific exercise when CHOelectrolyte beverages were consumed regularly. Therefore, the metabolic effects of CHO beverage consumption throughout soccer match play remain unclear.Objective: To investigate the blood glucose and blood lactate responses to CHOs ingested before and during soccer match play.Design: Crossover study. Setting: Applied research study.Patients or Other Participants: Ten male outfield academy soccer players (age ¼ 15.6 6 0.2 years, height ¼ 1.74 6 0.02 m, mass ¼ 65.3 6 1.9 kg, estimated maximal oxygen consumption ¼ 58.4 6 0.8 mLÁkg À1 Ámin À1). Intervention(s): Players received a 6% CHO-electrolyte solution or an electrolyte (placebo) solution 2 hours before kickoff, before each half (within 10 minutes), and every 15 minutes throughout exercise. Blood samples were obtained at rest, every 15 minutes during the match (first half: 0-15, 15-30, and 30-45 minutes; second half: 45-60, 60-75, and 75-90 minutes) and 10 minutes into the halftime break.Main Outcome Measure(s): Metabolic responses (blood glucose and blood lactate concentrations) and markers of exercise intensity (heart rate) were recorded.Results: Supplementation influenced the blood glucose response to exercise (time 3 treatment interaction effect: P .05), such that glucose concentrations were higher at 30 to 45 minutes in the CHO than in the placebo condition. However, in the second half, blood glucose concentrations were similar between conditions because of transient reductions from peak values occurring in both trials at halftime. Blood lactate concentrations were elevated above those at rest in the first 15 minutes of exercise (time-of-sample effect: P , .001) and remained elevated throughout exercise. Supplementation did not influence the pattern of response (time 3 treatment interaction effect: P ¼ .49).Conclusions: Ingestion of a 6% CHO-electrolyte beverage before and during soccer match play did not benefit blood glucose concentrations throughout the second half of exercise.Key Words: supplementation, sports drinks, football, intermittent exercise, rebound hypoglycemia Key PointsA 6% carbohydrate-electrolyte beverage ingested before and during soccer match play did not maintain blood glucose concentrations in the second half of match play. The efficacy of carbohydrate-fluid supplementation regimes that are recommended for high-intensity intermittent team sports players can be improved, and more effective carbohydrate-supplementation strategies can be developed to maintain blood glucose concentrations throughout soccer match play.
