“…Therefore, in total, 15 studies were included; 13 studies were published as full-text manuscripts in peer-reviewed journals, one study was published as a conference abstract, and one study is a part of a master's thesis. [4][5][6][7][8]13,15,16,[22][23][24][25][26][27][28] Eleven studies explored the effects of caffeine, whereas five studies examined the effects of sodium bicarbonate on Yo-Yo test performance (Table 1). One study included examined the isolated effects of both caffeine and sodium bicarbonate.…”

“…3 The effects of caffeine and sodium bicarbonate have also been explored in the context of Yo-Yo test performance, with equivocal findings. [4][5][6][7][8] Some reported an increase in performance following the ingestion of either caffeine or sodium bicarbonate, while others report that performance in this test is unaffected by the use of these supplements. [4][5][6][7][8] Differences between the studies such as the dose, ingestion timing, and training status may explain some of these https://doi.org/10.1016/j.jsams.2019.08.016 1440-2440/© 2019 Sports Medicine Australia.…”

“…While the effects of caffeine have been explored using a meta-analytic approach, no previous meta-analyses explored the effects of sodium bicarbonate on performance in the Yo-Yo test. A meta-analysis exploring the effects of sodium bicarbonate on performance in this test is needed because: (a) the equivocal evidence on this topic presented in the literature; 5,6,8 and, (b) the common anecdotal use of sodium bicarbonate by athletes. 17 Therefore, the aim of this review was to explore the effects of caffeine and sodium bicarbonate on performance in the Yo-Yo testing using a metaanalysis and highlight the practical application of these findings.…”

Objectives: To conduct a systematic review and a meta-analysis of studies exploring the effects of caffeine and/or sodium bicarbonate on performance in the Yo-Yo test. Design: Systematic review and meta-analysis. Methods: A total of six databases were searched, and random-effects meta-analyses were performed examining the isolated effects of caffeine and sodium bicarbonate on performance in the Yo-Yo test. Results: After reviewing 988 search records, 15 studies were included. For the effects of caffeine on performance in the Yo-Yo test, the meta-analysis indicated a significant favoring of caffeine as compared with the placebo conditions (p = 0.022; standardized mean difference [SMD] = 0.17; 95% CI: 0.08, 0.32; +7.5%). Subgroup analyses indicated that the effects of caffeine were significant for the level 2 version of the Yo-Yo test, but not level 1. Four out of the five studies that explored the effects of sodium bicarbonate used the level 2 version of the Yo-Yo test. The pooled SMD favored the sodium bicarbonate condition as compared with the placebo/control conditions (p = 0.007; SMD: 0.36; 95% CI: 0.10, 0.63; +16.0%). Conclusions: This review demonstrates that isolated ingestion of caffeine and sodium bicarbonate enhances performance in the Yo-Yo test. Given these ergogenic effects, the intake of caffeine and sodium bicarbonate before the Yo-Yo test needs to be standardized (i.e., either restricted or used in the same way before each testing session). Furthermore, the results suggest that individuals competing in sports involving intermittent exercise may consider supplementing with caffeine or sodium bicarbonate for acute improvements in performance.

Background: Although Yo-Yo intermittent tests are frequently used in a variety of sports and research studies to determine physical fitness, no structured reference exists for comparison and rating of test results. This systematic review of the most common Yo-Yo tests aimed to provide reference values for test results by statistical aggregation of published data.Methods: A systematic literature search for articles published until August 2017 was performed in MEDLINE, Web of Science, SPORTDiscus and Google Scholar. Original reports on healthy females and males ≥16 years were eligible for the analysis. Sub-maximal test versions and the Yo-Yo Intermittent Recovery Level 1 Children's test (YYIR1C) were not included.Results: 248 studies with 9,440 participants were included in the structured analysis. The Yo-Yo test types most frequently used were the Yo-Yo Intermittent Recovery Level 1 (YYIR1, 57.7%), the Yo-Yo Intermittent Recovery Level 2 (YYIR2, 28.0%), the Yo-Yo Intermittent Endurance Level 2 (YYIE2, 11.4%), and the Yo-Yo Intermittent Endurance Level 1 (YYIE1, 2.9%) test. For each separate test, reference values (global means and percentiles) for sports at different levels and both genders were calculated.Conclusions: Our analysis provides evidence that Yo-Yo intermittent tests reference values differ with respect to the type and level of sport performed.The presented results may be used by practitioners, trainers and athletes to rate Yo-Yo intermittent test performance levels and monitor training effects.

“…•kg −1 of NaHCO 3 extended the distance by 14% when the same exercise was performed. In addition, Jason[11] et al have presented that a distance extension of 12.4% was observed when 0.3 g of NaHCO 3 was ingested prior to the same exercise. These previous studies have shown the ergogenic effect of NaHCO 3 on high-intensity exercise state, which allows the performance of short-term, intermittent and anaerobic Yo-Yo IR2 under metabolic stress.…”

In this study, we investigated the effect of sodium bicarbonate (NaHCO 3) supplementation at a dose of 0.2 g•kg −1 40 min before an exercise on intermittent endurance performance and gastrointestinal distress. The participants were six healthy male students of a university. The Yo-Yo intermittent recovery test level 2 (Yo-Yo IR2) was used for the evaluation of intermittent endurance. The participants ingested water (Cont) or NaHCO 3 independently at three timings. After drinking water, the Yo-Yo IR1 was performed for 2 min as warm-up. After resting for 5 min, the Yo-Yo IR2 was initiated. The measurement items were exercise distance, nutrition intake, biochemical test results, and blood gas analysis findings. The participants who ingested NaHCO 3 had a 14% extended distance than those who ingested Cont, and 2/3 of those who took NaHCO 3 showed a better motor performance. No significant difference was observed between the participants who took Cont and NaHCO 3 in terms of pH level at baseline, and the NaHCO 3 level was significantly higher during pre-and post-exercise (p < 0.05). No significant difference was observed between the participants who took Cont and NaHCO 3 in terms of bicarbonate ion level at baseline, and the NaHCO 3 level was significantly higher during pre-and post-exercise (p < 0.05). In conclusion, even when the participants ingested NaHCO 3 at a low dose (0.2 g•kg −1), their exercise ability during an intermittent endurance test has improved. Furthermore, when digestive absorption is considered, eating a meal in advance may be able to suppress the onset of gastrointestinal distress.
