“…In our study, we studied highly trained male tennis players, while the study of Cuenca et al [46] was conducted with young active male players. In addition to the evidence previously reported, some studies did not find a positive effect of NO 3 − supplementation on peak power during a cycle ergometer test [29,47], while other studies found improvement in peak power on a cycle ergometer [46,48,49] and strength performance [50,51], but not during a vertical jump [46]. Hence, controversial evidence about the effects of BJ supplementation on several aspects of physical performance, such as muscle force or power, are presented in the literature.…”

“…However, in intermittent efforts, there is controversial evidence regarding the ergogenic effect of BJ [40,42]. While several days of BJ administration may stimulate a modification of contractile properties of the muscle, allowing the generation of higher rates of power, enhancing speed in short distances and duration tests [27,29,30], no significant differences were found after the acute ingestion of BJ [28,36]. In this study, we observed no changes in the different explosive actions related to physical tennis performance (e.g., SVT, CMJ, HIS, 5-0-5, and 10-m) with the ingestion of BJ against PLA.…”

“…Furthermore, it has been suggested that ingestion of BJ may be particularly effective in intermittent sports at augmenting different physiological processes, such as calcium-handling proteins and contractile force in type II (fast-twitch) muscle fibers [28]. However, controversial findings are reported in the scientific literature, with some studies showing improvements in repeated-sprint performance by reducing time to reach peak power (~2.8) [29,30], while other studies do not report any difference between BJ and placebo (PLA) conditions [31]. In tennis, only one study developed by Aksit et al [32] examined the relationships between simulated tennis performance test and circulating NOx (i.e., sum NO 3 − + NO 2 − ) levels.…”

Beetroot juice (BJ) contains high levels of inorganic nitrate (NO3−) and its intake has good evidence in increasing blood nitrate/nitrite concentrations. The ingestion of BJ has been associated with improvements in physical performance of endurance sports, however the literature in intermittent sports is scarce. The aim of this study was to investigate whether BJ could improve physical performance in tennis players. Thirteen well-trained tennis players (25.4 ± 5.1 years) participated in the study during their preparatory period for the tennis season. Subjects were randomly divided into two groups and performed a neuromuscular test battery after either BJ or placebo (PLA) consumption. Both trials were executed on two separate days, in randomized order, with one week of wash out period. The test battery consisted of serve velocity test (SVT), countermovement jump (CMJ), isometric handgrip strength (IHS), 5-0-5 agility test (5-0-5), and 10 m sprint (10-m). No significant differences were found in SVT (1.19%; p = 0.536), CMJ (0.96%; p = 0.327), IHS (4.06%; p = 0.069), 5-0-5 dominant and nondominant side (1.11–2.02%; p = 0.071–0.191) and 10-m (1.05%; p = 0.277) when comparing BJ and PLA ingestion. Thus, our data suggest that low doses of BJ (70 mL) consumption do not enhance tennis physical performance.

“…However, our ndings determined that acute BJ intake did not improve time trial performance in welltrained triathletes [19]. In anaerobic assessment, peak power was not different between BJ supplementation and placebo (PL) conditions in recreational, competitive and elite sprint athletes in the Wingate test [21]. Other studies have found increases in peak power levels during the Wingate test [22].…”

Background: Acute beetroot juice (BJ) intake has shown to enhance aerobic and anaerobic performance. However, no studies have evaluated the effects of BJ intake on CrossFit (CF) performance by linking hormonal, metabolic, and mechanical responses. The purpose of this study was to determine the causal physiological association between hormonal, metabolic and mechanical responses, and CF workouts performance after acute BJ intake. Methods: Twelve well-trained male practitioners undertook a CF workout after drinking 140 mL of BJ (~ 12.8 mmol NO3−) or placebo. The two experimental conditions (BJ or placebo) were administered using a randomized, double-blind, crossover design. The CF workout consisted of repeating the same exercise routine twice: Wall ball (WB) shots plus full back squat (FBS) with 3-min rest (1st routine) or without rest (2nd routine) between the two exercises. A 3-min rest was established between the two exercise routines. Results: An interaction effect was observed in the number of repetitions performed (p = 0.04). The Bonferroni test determined a higher number of repetitions after BJ than placebo intake when a 3-min rest between WB and FBS (1st routine) was established (p = 0.007). An interaction effect was detected in cortisol response (p = 0.04). Cortisol showed a higher increase after BJ compared to placebo intake (76% vs. 36%, respectively). No interaction effect was observed in the testosterone and testosterone/cortisol ratio (p > 0.05). A significant interaction effect was found in oxygen saturation (p = 0.01). A greater oxygen saturation drop was observed in BJ compared to placebo (p < 0.05). An interaction effect was verified in muscular fatigue (p = 0.03) with a higher muscular fatigue being observed with BJ than placebo (p = 0.02). Conclusions: BJ intake improved anaerobic performance only after the recovery time between exercises. This increase in performance in the first routine probably generated greater hypoxia in the muscle mass involved, possibly conditioning post-exercise performance. This was observed with a fall in oxygen saturation and in muscle fatigue measured at the end of the CF workout. The greatest perceived changes in cortisol levels after BJ intake could be attributed to the nitrate-nitrite-nitric oxide pathway

“…Besides reducing VO 2 , BRJ ingestion seems to increase skeletal muscle power or the time required to reach maximal power output (Coggan et al 2015;Dominguez, Garnacho-Castano, et al, 2017;Jonvik et al 2018;Lansley, Winyard, Bailey, et al 2011), as well as electrically evoked muscle force (Haider and Folland 2014;Whitfield et al 2017). Interestingly, Haider and Folland (2014) found that after 7day BRJ supplementation, muscle force was increased during electrical stimulation, but not during voluntary contractions of the subjects.…”

Beetroot juice (BRJ) has become increasingly popular amongst athletes aiming to improve sport performances. BRJ contains high concentrations of nitrate, which can be converted into nitric oxide (NO) after consumption. NO has various functions in the human body, including a vasodilatory effect, which reduces blood pressure and increases oxygen-and nutrient delivery to various organs. These effects indicate that BRJ may have relevant applications in prevention and treatment of cardiovascular disease. Furthermore, the consumption of BRJ also has an impact on oxygen delivery to skeletal muscles, muscle efficiency, tolerance and endurance and may thus have a positive impact on sports performances. Aside from the beneficial aspects of BRJ consumption, there may also be potential health risks. Drinking BRJ may easily increase nitrate intake above the acceptable daily intake, which is known to stimulate the endogenous formation of N-nitroso compounds (NOC's), a class of compounds that is known to be carcinogenic and that may also induce several other adverse effects. Compared to studies on the beneficial effects, the amount of data and literature on the negative effects of BRJ is rather limited, and should be increased in order to perform a balanced risk assessment.
