A single dose of beetroot juice not enhance performance during intervallic swimming efforts
| Resumo: | Despite the numerous scientific evidence on the topic, there is no clear and consistent answer that clarifies the true effects of beet- root juice (BJ) supplementation on different types of physical per- formance. This study examined whether an acute intake of BJ im- proves swimming performance, physiological variables of anaer- obic metabolism, or subjective measures during high-intensity in- terval exercise with incomplete rest in competitive swimmers. Eighteen competitive swimmers (nine females and nine males) participated in this cross-over randomized, placebo-controlled, double-blind and counterbalanced study. In two trials, swimmers ingested BJ (70 mL, 6.4 mmol/400 mg NO3-) or placebo (PLA) (70 mL, 0.04 mmol/3 mg NO3-) three hours before a 2×6×100 m maximal effort with 40 seconds rest between repetitions and three minutes between blocks. The 100 m times showed no differences between groups (p > 0.05), but there was an interaction between block×repetition×condition (F5 = 3.10; p = 0.046; ηp2 = 0.54), in- dicating that the BJ group decreased the time of the sixth repeti- tion of block2 compared to block1 (p = 0.01). Lactate concentra- tion showed no differences between conditions (p > 0.05), but there was a main effect of block (ηp2 = 0.60) and a block×repeti- tion interaction (ηp2 = 0.70), indicating higher values in block2 and increasing values between repetitions in block1. The subjec- tive scales, perception of exertion (RPE) and Total Quality Re- covery (TQR), showed no effects of condition (p > 0.05), but BJ swimmers had a greater TQR in the last repetitions of each block. In conclusion, a single dose of BJ did not enhance intermittent swimming performance or modified the physiological (lactate and heart rate) or subjective (RPE and TQR) variables; although there was a possible positive effect on the exercise tolerance at the end of effort. |
