24. Repeated-sprint performance and plasma responses following beetroot juice supplementation do not differ between recreational, competitive and elite sprint athletes. Full Text available with Trip Pro

Repeated-sprint performance and plasma responses following beetroot juice supplementation do not differ between recreational, competitive and elite sprint athletes. There is an ongoing debate whether highly trained athletes are less responsive to the ergogenic properties of nitrate. We assessed the effects of nitrate supplementation on plasma nitrate and nitrite concentrations and repeated-sprint performance in recreational, competitive and elite sprint athletes.In a randomized double-blinded (...) cross-over design, recreational cyclists (n = 20), national talent speed-skaters (n = 22) and Olympic-level track cyclists (n = 10) underwent two 6-day supplementation periods; 140 mL/d nitrate-rich (BR; ∼800 mg/d) and nitrate-depleted (PLA; ∼0.5 mg/d) beetroot juice. Blood samples were collected and three 30-s Wingate tests were performed.Plasma nitrate and nitrite concentrations were higher following BR vs PLA (P < .001), with no differences between sport levels (all P > .10).

, exercise tolerance, and endurance exercise performance. In addition, more recent evidence suggests that dietary nitrate has the potential to enhance team-sport-specific high-intensity intermittent exercise performance. Indeed, chronic dietary nitrate supplementation (2-6 days) has been reported to increase the distance covered before exhaustion during the Yo-Yo intermittent recovery level 1 test, a well-established and ecologically valid test widely used to mimic the high-intensity running bouts (...) of soccer match-play. However, while these findings suggest that nitrate may be an effective ergogenic aid for team-sport players when consumed daily, it is currently unclear if the improvement in team-sport specific intermittent exercise performance can be achieved following a single bolus of dietary nitrate. Given the increasing interest and use of dietary nitrate as an ergogenic aid by team-sport players, establishing the shortest period of supplementation required to elicit an ergogenic effect

38. Beta-alanine supplementation enhances judo-related performance in highly-trained athletes. Full Text available with Trip Pro

Beta-alanine supplementation enhances judo-related performance in highly-trained athletes. In official judo competitions, athletes usually engage in 5-7 matches in the same day, performing numerous high-intensity efforts interspersed by short recovery intervals. Thus, glycolytic demand in judo is high and acidosis may limit performance. Carnosine is a relevant intracellular acid buffer whose content is increased with beta-alanine supplementation. Thus, we hypothesized that beta-alanine (...) supplementation improved the number of throws per set and the total number of throws (both p<0.05). Placebo did not change these variables (both p>0.05). Blood pH and HCO3- reduced after exercise (all p<0.001), with no between-group differences (all p>0.05). However, the lactate response to exercise increased in the beta-alanine group as compared to placebo (p<0.05).In conclusion, 4 weeks of beta-alanine supplementation effectively enhance judo-related performance in highly-trained athletes.Copyright © 2016

Effect of Dietary Nitrate Supplementation on Swimming Performance in Trained Swimmers. Nitrate supplementation appears to be most ergogenic when oxygen availability is restricted and subsequently may be particularly beneficial for swimming performance due to the breath-hold element of this sport. This represents the first investigation of nitrate supplementation and swimming time-trial (TT) performance. In a randomized double-blind repeated-measures crossover study, ten (5 male, 5 female (...) ) trained swimmers ingested 140ml nitrate-rich (~12.5mmol nitrate) or nitrate-depleted (~0.01mmol nitrate) beetroot juice. Three hours later, subjects completed a maximal effort swim TT comprising 168m (8 × 21m lengths) backstroke. Preexercise fractional exhaled nitric oxide concentration was significantly elevated with nitrate compared with placebo, Mean (SD): 17 (9) vs. 7 (3)p.p.b., p = .008.
