The study investigated 194 matches (74 women's and 120 men's matches) where at least one of the two competitors received the second shido. The penalties affected the attack frequency (F 2, 360 = 30.81, p < 0.001). The attack frequency was the highe...

The main aim of this study was to analyse the relationship between how contests end (scores or penalties), the temporal units and the competition rounds regarding when the contest end in the 2018, 2019 and 2021 Judo World Championships. A total of 2340 contests involving 2244 elite judo athletes (1343 men and 901 women) were analysed. Pearson’s chi...

Purpose Yoga may be a beneficial treatment for people with Parkinson’s disease (PD). However, no studies have critically reviewed and meta-analyzed the scientific evidence for yoga’s benefits regarding motor and non-motor symptoms. The purpose of this study was to conduct a systematic review and meta-analysis on the effectiveness of yoga as a rehab...

The present study aimed (1) to propose an approach of observational analysis of the preceding standing judo (tachi-waza (TW)) context to a groundwork (ne-waza (NW)) grappling score (NWGS), and (2) to analyze the outcomes of applying such a model in high-level judoists. We conducted an observational analysis of 176 NW scoring actions of 794 combats...

Despite numerous studies related to dehydration there is still a lack of scientific literature presenting hydration status and fluid intake of judo athletes during different periods. Therefore, the aim of this study was to investigate, fluid intake, hydration status and body weight changes of young judo athletes during a typical day of training in...

Objective: To assess whether a slackline intervention program improves postural control in children/adolescents with spastic cerebral palsy (CP). Design: Randomized controlled trial. Setting: Patients' association. Participants: Twenty-seven children/adolescents with spastic CP (9-16 years) were randomly assigned to a slackline intervention...

This study explored the changes in load-velocity relationship of bench press and parallel squat exercises following two programs differing in the set configuration. A randomized controlled trial was carried out in a sample of 39 physically active individuals. Participants were assigned to rest redistribution set configuration, traditional set confi...

The goal of this study was to assess the effects of a supervised slackline training program in a group of soccer players. Thirty-four male division I under-19 players (16.64 ± 0.81 years) agreed to participate in the study. They were randomly divided into an experimental group (EG) and a control group (CG). The first group (EG) followed a 6-week su...

The aim was to evaluate the effects of judo combat on the athletes’ postural control (PC) and physiological loading before, during and after a simulated match. Seventeen under-20 regional- and national-level athletes completed one modified 7-minutes match. At baseline, during the combat (3rd and 7th minutes) and 2-minutes post-match centre of press...

The aims of this study were to compare the goodness of fit and the concurrent validity of three regression models of the force-velocity relationship in a unilateral knee extension exercise. The force-velocity relationship and the one-repetition-maximum load in the dominant and non-dominant leg were obtained in 24 male sports sciences students by a...

Background: Progressive resistance exercise (PRE) can have a positive effect in individuals with Parkinson's disease (PD). However, the effect of PRE may vary with the clinical subtype of PD. To date, no study has assessed the effects of PRE in the different subtypes of PD. Aim: The aim of the present study was to assess the effects of PRE in PD...

Purpose: The aim of this study was to assess whether supervised slackline training reduces the risk of falls in people with Parkinson's disease (PD). Methods: Twenty-two patients with idiopathic PD were randomized into experimental (EG, N = 11) and control (CG, N = 11) groups. Center of Pressure (CoP), Freezing of Gait (FOG), and Falls Efficacy...

Literature has shown a relationship between laterality and an over-representation of left-handed athletes in certain sports, and especially in sports one against one, such as judo, tennis, boxing or fencing; the main explanation has been attributed to greater chance of success. Some authors have explained it through a genetic or innate superiority...

The main goal of the study was to assess the effects of slackline training on the postural control system (PCS) and jump performance of athletes. 25 female basketball players were randomized into two groups; control (N=12) and experimental (N=13). The latter experienced a 6-week supervised slackline training (3 sessions per week, 5-9 minutes per se...

The main goal of this project was to assess top-level judo coaches' perceptions on two capital elements in coaching: training and competition management. 41 experienced, high-level coaches from Europe, Asia and America agreed to participate. An open-ended questionnaire was selected as the assessment instrument. The two main topics (training and com...
