Anthropometric, neuromuscular, physiologic and training variables as determinants to laboratory cycling performance.

Background: The goal of this study was to verify whether anthropometric, physiological and neuromuscular factors, as well as training characteristics, could predict cycling performance during maximal incremental and time-to-exhaustion tests.

Methods: Twenty cyclists were evaluated: Anthropometric variables, knee extensor muscle activation and architecture, training history, and training volume were assessed. Second ventilatory threshold (VT2), maximal oxygen uptake (VO2MAX), and maximal power output (POMAX) were assessed during the incremental test.

Variability Analysis in Judo Para Athletes With Visual Impairments: Match-Outcome Performance in the Tokyo 2020 Paralympic Games With Evidence From the New Classification System.

Match-related performance analysis in judo Para athletes with visual impairments is important to coaches and staff to identify technical-tactical profiles of their athletes and opponents but also to identify whether there are similar characteristics in each visual class. Thus, this study explores the match-related performance in judo Para athletes and verifies the relationship between performance using the old and new classification systems. The match-derived variables were analyzed using different statistical methods considering a total of 182 matches from the Tokyo 2020 Paralympic Games.

Participation in the International Judo Federation World Tour competitions and performance in Tokyo Olympic Games.

Introduction: The International Judo Federation introduced a ranking system in 2009 that determines top athletes for the Olympic Games and seeds them in competitions. Previous research indicated that this ranking list and past performances predicted 19%-27% of performance in the Olympic Games and World Championships. However, due to the COVID-19 pandemic, the relationship between Judo World Tour competitions and Olympic Games performance may have been affected.

Effect of Vertical Jump and Sprint Training on Power and Speed Performance Transfer.

The aim of this systematic review was to investigate the effect of specific sprint and vertical jump training interventions on transfer of speed-power parameters. The data search was carried out in three electronic databases (PubMed, SCOPUS, and SPORTDiscus), and 28 articles were selected (13 on vertical jump training and 15 on sprint training). We followed the PRISMA criteria for the construction of this systematic review and used the Physiotherapy Evidence Database (PEDro) scale to assess the quality of all studies.

Tactile and Auditory Stimuli Can Improve the Specific Physical Performance of Para-Judo Athletes With Varied Origins of Visual Impairment.

Our aim in this study was to compare performance adaptations based on tactile or sonorous stimuli in para-judo athletes with congenital or acquired visual impairment. Twenty judo athletes with a type of visual impairment performed both the adapted Special Judo Fitness Test (SJFT) with tactile and sonorous stimuli and the standard SJFT. We used two-way ANOVA with repeated measurements in the second factor to compare the SJFT performance of athletes with visual impairment between two groups (acquired or congenital) in the two test situations, with the level of significance set at < .

More time for judo matches? Analysis of type of techniques, time, scores, and penalties in the Tokyo 2020 Olympic Games.

This study aimed to analyze the distribution of judo matches in the Tokyo 2020 Olympic Games, considering matches in the regular duration (≤4 min) and during the extra time (the golden score) according to sex, scores, penalties, phases of competition, weight categories, and judo techniques. The data were extracted from the Official Results Books of the Olympic Games in Tokyo 2020. The combats were divided in matches that were finished in the regular duration and that were finished by the golden score, with a total of 450 matches.

Acute Dehydration Impairs Performance and Physiological Responses in Highly Trained Judo Athletes.

Background: The present study investigated highly trained male judo athletes and how a 5% body mass dehydration affects their judo-specific performance and physiological responses. Methods: Nine highly trained international-level male judo athletes who are weight-cyclers voluntarily participated in the study. The study had a controlled crossover design in nature.

Injuries in Judo Athletes With Disabilities: Prevalence, Magnitude, and Sport-Related Mechanisms.

Context: The participation of judo athletes with disabilities in competitions has increased over the years as well as the burden of sports-related injuries and illnesses in this population. However, there is limited knowledge about sports-related injuries in judo athletes with different disabilities.

Objective: To investigate the prevalence of injuries in judo athletes with disabilities, considering the different impairment groups, magnitude of injury (ie, mechanism, nature, and severity of injury), and specific body parts.

Time-Trial Performance of Para-Cycling Athletes With Visual Impairment in Tandem Competitions: A Retrospective Analysis of 20 Yrs.

Identifying performance variables associated with visual impairment classification in para-cycling is one of the steps to improve the evidence-based classification system, and consequently, bring equality in Paralympic sports. Thus, this retrospective study aimed to analyze a 1-km tandem-track race performance among para-cyclists (male and female) with different visual impairment degrees (B1, B2, and B3) and to verify the retrospective performance over 20 yrs in all sport classes. The data were extracted from 427 para-cyclists (251 male and 176 female) who competed in the Para-Cycling World Championships and Paralympic Games.
