Photogrammetric evaluation of body posture of 6-year-old boys training judo, in three repeated assessments.

Purpose: The purpose of this work was to assess changes in body posture in a group of 6-year-old boys training judo, compared to a control group, in three repeated examinations.

Methods: The study included 88 boys aged 6. Fifty-one of them started judo training in sports clubs at the beginning of the school year (JU).

Meta-Analysis to Determine Normative Values for the Special Judo Fitness Test in Male Athletes: 20+ Years of Sport-Specific Data and the Lasting Legacy of Stanisław Sterkowicz.

The aim of this study was to evaluate Special Judo Fitness Test (SJFT) results specific to the population of male judoka and to develop age category norms for junior and senior athletes. A systematic review of the existing literature was conducted to identify 281 publications reporting SJFT results between 1995 and 2018. The final meta-analysis included data from 37 relevant studies that reported SJFT results from 51 individual samples of 515 senior and 209 junior male athletes.

Somatotype, body composition, and physical fitness in artistic gymnasts depending on age and preferred event.

In men's artistic gymnastics, results that are particularly appreciated are those obtained in all-around and individual events such as the floor exercise, pommel horse, rings, vault, parallel bars and horizontal bar. However, few studies have explored the dependency of anthropometric characteristics and fitness from age category or the event preferred by gymnasts. Therefore, the aim of this study is to compare the somatic type, body composition and values of some anthropometric and fitness characteristics and indices of gymnasts according to age and preferred event.

Evaluation of somatotype in artistic gymnastics competitors: a meta-analytical approach.

Introduction: Studies on the anthropometric characteristics of athletes have a long history, but there are no published reviews on the somatotype of artistic gymnasts. Practitioners and professional coaches can gain guidance from improved understanding of the ideal body constitution and the impact of high-intensity training since preadolescence on body build. The present review is designed to provide this information.

Sex differences and the effects of modified combat regulations on endurance capacity in judo athletes: A meta-analytic approach.

Judo requires endurance capacity to recover from its high-intensity intermittent actions. This systematic review aimed to evaluate VO2max and the anaerobic threshold in competitive male and female judo athletes. Twelve eligible studies were chosen for quantitative meta-analysis, including results for 188 male and 159 female athletes.

Assessment of the impact of regular judo practice on body posture, balance, and lower limbs mechanical output in six-year-old boys.

Background: Physical activity is beneficial for young children. The aim of this study was to monitor the changes in body posture and balance, as well as in the level of lower limbs mechanical output in six-year-old boys practicing judo (JU) and in a group not practicing that sport (NT).

Methods: In 12 matched pairs of boys (JU+NT) body mass and height were measured and Body Mass Index (BMI) was calculated at three time points (baseline, three months, six months).

Evaluation of Sex-Specific Movement Patterns in Judo Using Probabilistic Neural Networks.

The purpose of the present study was to create a probabilistic neural network to clarify the understanding of movement patterns in international judo competitions by gender. Analysis of 773 male and 638 female bouts was utilized to identify movements during the approach, gripping, attack (including biomechanical designations), groundwork, defense, and pause phases. Probabilistic neural network and chi-square (χ) tests modeled and compared frequencies (p ≤ .

Sex and Weight Category Differences in Time-Motion Analysis of Elite Judo Athletes: Implications for Assessment and Training.

Sterkowicz-Przybycień, K, Miarka, B, and Fukuda, DH. Sex and weight category differences in time-motion analysis of elite judo athletes: implications for assessment and training. J Strength Cond Res 31(3): 817-825, 2017-The purpose of this investigation was to support training program development through the comparison of combat and pause phases during elite male and female judo competition in athletes of varying weight categories.

Effect of Acute Effort on Isometric Strength and Body Balance: Trained vs. Untrained Paradigm.

Years of training in competitive sports leads to human body adaptation to a specific type of exercise. In judo bouts, maintaining hand grip on an opponent's clothes and postural balance is essential for the effective technical and tactical actions. This study compares changes after maximal anaerobic exercise among judo athletes and untrained subjects regarding 1) maximum isometric handgrip strength (HGSmax) and accuracy at the perceived 50% maximum handgrip force (1/2HGSmax) and 2) the balance of 13 judo athletes at national (n = 8) and international (n = 5) competitive levels and 19 untrained university students.

Special Judo Fitness Test Level and Anthropometric Profile of Elite Spanish Judo Athletes.

Casals, C, Huertas, JR, Franchini, E, Sterkowicz-Przybycień, K, Sterkowicz, S, Gutiérrez-García, C, and Escobar-Molina, R. Special judo fitness test level and anthropometric profile of elite spanish judo athletes. J Strength Cond Res 31(5): 1229-1235, 2017-The aim of this study was to determine the anthropometric variables that best predict Special Judo Fitness Test (SJFT) performance.

Sport skill level and gender with relation to age, physical development and special fitness of the participants of Olympic volleyball tournament Beijing 2008.

The aim of this study was to provide an answer to the question whether and how age, body height, body mass, body mass index and results from fitness tests are related to sport skill level and gender of the participants of the Olympic volleyball tournament. Two-Way ANOVA was used to find the dependency of the variables on the factor of sport skill level (A--teams which took places 1 to 4, B--places from 5 to 8; C--places from 9 to 12) and gender (F--female; M--male). Statistical significance was set at p < 0.

Establishing normative data for the special judo fitness test in female athletes using systematic review and meta-analysis.

Conflicting results have been documented in the Special Judo Fitness Test (SJFT) for mean parameters of performance between male and female judo athletes matched by age and competitive level. Therefore, it is debatable whether previously established norms for the SJFT prepared for men, should be adopted for use in women. The goal of this investigation was to prepare standards to allow coaches and researchers to control and evaluate training effects in female judoka.

Somatotype, body composition and proportionality in polish top greco-roman wrestlers.

The objective of the paper was to determine body composition and somatotype of male Greco-Roman wrestlers grouped by different weight categories and level of competition. Twenty three contestants (aged 24.9±5.

Body composition and somatotype of the elite of Polish fencers.

The purpose of this study was to determine body composition and somatotype of the male fencers who were grouped by different fencing weapons. Analysis of body composition, with untrained men as background, will update the data necessary for the somatic profiles of fencers. Thirty contestants were examined during the Polish Fencing Championships in 2004.
