“…Isokinetic testing can provide valuable information about the strength of individual muscle groups and identify potential imbalance between them [ 30 ] where new elements of training and various training modalities might be essential to improving performance and preventing injuries due to lateral asymmetry [ 31 ]. Indeed, a recent study by Kons et al [ 32 ] showed that lower-limb muscle power was positively associated with judo-specific performance. Results in our study indicate that elite Serbian female judokas do not have an elevated risk of injury due to lateral or unilateral asymmetry between knee flexors and extensors in isokinetic muscle torques values.…”

Elite judo athletes undergo vigorous training to achieve outstanding results. In pursuit of achieving competitive success, the occurrence of injuries amongst judo athletes is not rare. The study aimed to perform a knee flexors and extensors isokinetic torque analysis in elite female judo athletes. Fifty-eight elite female judo athletes of the Serbian national team (21.02 ± 3.11 years; 62.36 ± 11.91 kg, 165.04 ± 10.24 cm, training experience 12.72 ± 2.98 years) volunteered to participate in this study. The range of motion (ROM) was set at 90⁰. Testing was performed in a concentric–concentric mode for the testing speed of 60 ⁰/s. Five maximal voluntary contractions of knee extensors and knee flexors muscle groups were measured for both legs. The obtained data showed a statistically significant difference in absolute torque values among different categories as heavier athletes demonstrated higher values. Post hoc analysis showed a significant difference between weight categories, as heavier athletes demonstrated higher values, while no significant differences in normalized torque values for different weight categories were observed. The implementation of new elements and training modalities may improve performance and prevent lateral asymmetry, thus reducing the risk of injury.

“…but quantifies specific qualities characterized in judo performance. The performance of UFT was previously associated with neuromuscular parameters in the lower limbs (e.g., vertical jump) and upper limbs (isokinetic shoulder rotation torque and maximal isometric handgrip strength) (68) and with aerobic and anaerobic indices (4,5).…”

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.

“…In order to determine the effects of different warm-up protocols on official competitions, researchers can use a number of specific judo tests that may provide some reference as an alternative method ( Lum, 2019 ; Merola et al, 2019 ). One of the well-accepted tests to simulate judo demands is the Uchikomi Fitness Test (UFT; Almansba et al, 2007 , 2012 ; Kons et al, 2021 ). UFT is a valid and reliable test to predict the performance of judokas in different training periods, as it was associated with both neuromuscular effort and cardiorespiratory adaptations and meeting the muscle strength and cardiovascular adaptations specific to judo ( Almansba et al, 2011 , 2012 ).…”

Performance is judged using a variety of methods to ensure uniformity between competitions. Uchikomi Fitness Test (UFT) could accomplished between morning qualifying and evening finals. The purpose of this study is to investigate the impact of different warm-up protocols on UFT at different times of the day in female judokas. Ten volunteer women who had been practising judo on a regular basis for more than 5 years and actively competed in international tournaments took part in this study. Judokas completed UFT, either after no-warm-up (NWU), specific warm-up (SWU), and linear+lateral warm-up (FWU) protocols for two times a day in the morning: 09:00–11:00 and in the evening: 16:00–18:00, on non-consecutive days. In conclusion, there was a significant increase in UFT scores (F = 9.89; p = 0.002), a + b (F = 4.42; p = 0.04) and heart rate (F = 28.99; p < 0.001) in the early evening compared to the morning. Increases in UFT performance were observed in the SWU protocol compared to the NWU and FWU protocols (p < 0.05). However, the interaction between time of day and warm protocol was not significant (p > 0.05). The UFT performance revealed diurnal variation, and the judokas’ performances may be favourably affected more in the late hours, particularly following SWU procedures.
