“…While testing times were kept consistent between participants in the present investigation, direct manipulation of the time of testing was not carried out. Since it has been generally shown that power-based performance suffers during morning times [ 37 , 38 ], thresholds for performance improvement may be lower which may have not been fully realized given the current study design. Although speculative, the lack of improvements in power output with PT may be related to a lower opportunity for performance enhancement as various testing times were used.…”

Various tastes including sweet, bitter, and sour have been shown to differentially influence physiological and psychological processes. Furthermore, ingestion of bitter and sweet solutions has been shown to acutely enhance exercise performance. However, the taste is highly individualized, and it is unclear if preference influences the ergogenic potential of taste. The purpose of this study was to investigate the effects of preferred and non-preferred drink tastes on anaerobic performance and psychological responses thereof. Physically active females participated in two counterbalanced sprint trials each with a different condition: (1) non-preferred taste (NPT), (2) Preferred taste (PT). Participants self-reported taste preferences (sweet, sour, bitter) with the highest-ranked taste being used for the PT condition and the lowest-ranked for NPT. For each visit, participants completed a 15 s Wingate Anaerobic Test (WAnT) prior to (PRE) ingestion of ~20 mL of their NP or PREF taste. Following ingestion, participants completed 2 min of active recovery, rated their taste preference of the solution, and completed another 15 s WAnT. The rate of perceived exertion (RPE), motivation, and enjoyment were measured through a visual analog scale following each WAnT. Anaerobic performance measures and heart rate (HR) were also obtained at the succession of each WAnT. Findings revealed no differences between taste conditions for mean power (p = 0.455), peak power (p = 0.824), or HR (p = 0.847). RPE was significantly lower with PT versus NPT (p = 0.006). Exercise enjoyment (p = 0.022) was higher with PT compared to NPT. NPT resulted in worse motivation compared to PRE (p = 0.001) while no changes were observed between PT and PRE (p = 0.197). These findings suggest that preferred drink taste may not enhance acute performance but improves psychological responses to maximal anaerobic exercise which may have implications for improving exercise training and adherence.

“…For example, Eken et al (31) found that SJFT performance was increased in the evening hours compared with morning hours in female judo athletes after protocols that elevated heart rate, demonstrating an effect of the time of day. Ouergui et al (79) found high performance of JGST (both modes) in the afternoon compared with the morning; however, the SJFT and JPFT performances did not differ between the times of day. Therefore, it is recommended to ensure that repeated test sessions are performed at the same time of the day to avoid the influence of diurnal variation on the test results.…”

“…The second perspective was related to JPFT performance considering diurnal variation. Ouergui et al (79) investigated the effects of time of day on judo athletes and the relationship between psychological and perceived exertion (CR10) after the test in 12 male judo athletes. The results showed that the rating of perceived exertion after the JPFT was higher in the morning compared with the afternoon, and the physical activity enjoyment scale after JPFT was higher in the morning compared with midday, demonstrating that diurnal variation influences JPFT performance.…”

This narrative review aims to describe and provide usage directions for different types of judo-specific assessments based on the physical demands required by athletes during training and competition. Several judo-specific tests have been developed to test different physical capacities (e.g., aerobic and anaerobic capacities, strength endurance, etc). Judo skills or techniques are used to identify variables involved in performance, such as uchi-komi (technique repetition or repetition training), throws, displacements, grips on the judogi, and the like. Although all the tests can be used to identify the physical profile of each athlete and monitor training effects (acute, subacute, or chronic), some can also be used to prescribe training loads. The judo-specific tests analyzed in this study are a valid and accessible alternative to assess the physical performance of judo athletes, regardless of sex or weight category. These tests are recommended at different times (over the season) to monitor training effects or to prescribe training loads (when possible). Future studies could investigate other methods of validity (e.g., construct validity) in differentiated groups, as well as the sensitivity of the tests to detect changes (even if small) in performance.
