This study aimed to investigate the acute effects of simulated judo matches on fatigue and muscle damage markers. Twenty male athletes participated in this study. The performed three 5-minute separated by 15 minutes passive rest between each match. following measurements were before after match: shoulder external/internal rotation isokinetic torque countermovement jump (CMJ). Blood samples taken first match third for serum creatine kinase (CK) lactate dehydrogenase (LDH) analysis. T-tests...
Purpose: To determine the individual contributions of chronological age, somatic maturation, body size and composition, training experience as indicators performance in neuromuscular judo-specific assessments young athletes. Methods: Sixty-six youth judo athletes performed anthropometric measurements, tests-standing long jump test (SLJ), medicine ball throw (MBT), handgrip strength (HGS), tests-Special Judo Fitness (SJFT) Judogi Grip Isometric Strength Test (JGSTISO). A multiple linear...
The coach plays a fundamental role in high-performance sports, particularly relation to the development of athletes and achievement successful outcomes. Brazil holds significant relevance international judo, considering results obtained competitions Olympic Games. Understanding expert coaches can contribute new coaches. present study aimed investigate Brazilian judo A qualitative, retrospective case was conducted using semi-structured interview research design. Seven were interviewed for...
Context : Investigating parameters related to physical capacities, muscular imbalance between the limbs, and injury reports in judo athletes with vision impairments (VI) is something extremely relevant for competitive performance, especially considering absence of vision, which can be a determining factor these aspects. For this, this study aimed explore interlimb asymmetry bilateral strength index upper lower limbs VI describe association imbalance. Design A cross-sectional study. Methods...
This study analyzed the relationship between generic and judo-specific physical test performances technical-tactical competition among 19 female judo athletes. Participant data were gathered in two stages: (a) tests-countermovement jump (CMJ), handgrip strength, Special Judo Fitness Test Judogi Grip Strength Test; (b) match recorded for analysis. Pearson's linear correlation multiple regression analysis showed no significant correlations any parameter tests. However, number of attacks during...
Kons, RL, Ache-Dias, J, Detanico, D, Barth, and Dal Pupo, J. Is vertical jump height an indicator of athletes' power output in different sports modalities? J Strength Cond Res 32(3): 708-715, 2018-This study aimed to identify whether the ratio standard is adequate for scaling peak (PPO) body mass (BM) athletes verify classification agreement involved using PPO scaled BM (JH). One hundred twenty-four male divided into 3 groups-combat sports, team runners-participated this study. Participants...
This study aimed to investigate the relationship between physical performance and attack attempts effectiveness in official judo matches with different durations. Thirty-eight athletes participated this performed countermovement jump (CMJ), handgrip strength test (HGS), Judogi Grip Strength Test (JGST) Special Judo Fitness (SJFT). Official were filmed for technical-tactical analysis. The key results showed that male exhibited higher CMJ HGS than female group (p < 0.05). number of attacks was...
This study aimed to analyse the effects of a simulated Brazilian jiu-jitsu (BJJ) tournament on vertical jump performance, grip strength test and perceived effort responses. 22 male BJJ athletes participated in consisting three 7 min matches separated by 14 rest. Kimono (KGST), counter movement (CMJ) rate exertion (RPE) were measured before after each match, while RPE specific areas was assessed matches. ANOVA for repeated measures used compare parameters match with level significance set at...
This study aimed to verify the effect of judo matches on handgrip strength and perceptual responses during an official tournament in medalists nonmedalists. Thirty-four male athletes participated tournament. Before first match immediately after each match, maximum isometric rate perceived exertion overall specific areas were assessed. Analysis variance for repeated measures was used compare variables before t-test nonmedalists with level significance set at 5%. Also, size (ES) analysis used....
Background: The present study investigated highly trained male judo athletes and how a 5% body mass dehydration affects their judo-specific performance physiological responses. Methods: Nine international-level who are weight-cyclers voluntarily participated in the study. had controlled crossover design nature. Athletes completed three sessions, including familiarisation session two experimental sessions (dehydration (DEHY) control (CON)) with tests, maximal handgrip strength test (HGS),...
This study investigated how the time of day affects physical performance and perceptual responses in Brazilian Jiu-Jitsu (BJJ) athletes. Given significance circadian rhythms on athletic capabilities, we aimed to determine whether variations occur across different times (morning, 10:00–11:00h; afternoon, 14:00–15:00h; evening, 18:00–19:00h) if these effects differ by sex. In total, 23 BJJ athletes (9 females, 14 males) participated this study. The performed tests including maximal isometric...
This study analysed the modulation of jump performance, vertical stiffness as well joint and intralimb coordination throughout a 30-s test. Twenty male athletes performed test on force plate while undergoing kinematic analysis. Jump height, power output, ground contact time, stiffness, maximum knee hip flexion angles, by continuous relative phase (CRP) were analysed. Analysis variance was used to compare variables within deciles, t-tests CRP data between initial final jumps. Results showed...
Abstract Weldon, A, Cloak, R, Kirk, C, Ruddock, Langan-Evans, Detanico, D, Loturco, I, and Kons, R. Strength conditioning (S&C) practices of judo athletes S&C coaches: A survey-based investigation. J Cond Res 38(4): e160–e173, 2024—The benefits strength for improving performance reducing injuries have been widely studied. However, the used perspectives held by those delivering yet to be elucidated. Therefore, this study investigated judokas coaches working within judo. Forty-two 9...
Purpose This study aimed to relate strength parameters of the judogi pull test and countermovement jump (CMJ), body fat with mass compare in between dominant non-dominant hands. Methods Eighteen male judokas took part this study. The following were analysed: maximal force (F<sub>max</sub>), time (TF<sub>max</sub>), rate development (RFD) peak decrement (RPFD) nondominant hands during test. Jump height (H<sub>max</sub>), power, F<sub>max</sub>,...
The aim of this study was to identify force and velocity parameters related vertical jump performance in counter movement (CMJ) squat (SJ), compare these between sprint runners volleyball players. Twenty-four male athletes (12 regional/national-level 12 national-level players) participated study. performed CMJ SJ on a platform. following variables were analyzed: (jump height power), peak (PV), absolute relative maximum (Fmax), rate development (RFD,) time reach (TFmax). In CMJ, correlated...
AbstractThe objective of this study was to investigate the effects a simulated futsal match protocol on isokinetic knee torque production. Twenty-one young players participated in and performed futsal-specific comprising two blocks 20-minute activities simulate demands. At pre-protocol, half-time, post-protocol, concentric eccentric peak flexor extensor muscles, angle torque, conventional functional ratios were assessed. ANOVA used compare variables (significance level p < 0.05). A decrease...
