Comparison of lower limb segments kinematics in taekwondo kick. an approach to the proximal to distal motion

2015

Abstract In taekwondo, there is a lack of consensus about how the kick sequence occurs. The aim of this study was to analyse the peak velocity (resultant and value in each plane) of lower limb segments (thigh, shank and foot), and the time to reach this peak velocity in the kicking lower limb during the execution of the roundhouse kick technique. Ten experienced taekwondo athletes (five males and five females; mean age of 25.3 ±5.1 years; mean experience of 12.9 ±5.3 years) participated voluntarily in this study performing consecutive kicking trials to a target located at their sternum height. Measurements for the kinematic analysis were performed using two 3D force plates and an eight came…

Autoeficacia percibida y rendimiento técnico-táctico en taekwondistas universitarios

2016

Este trabajo analiza el rendimiento deportivo y la autopercepción por medio de metodología observacional y el análisis de autoeficacia, respectivamente, según el género y el éxito de los deportistas en taekwondo. Se presentan dos estudios: el estudio 1, con dos objetivos, pretendió analizar (i) las propiedades psicométricas del Cuestionario de Autoeficacia Percibida en Acciones de Taekwondo (CAPAT) y (ii) la autoeficacia de los taekwondistas según el género y el éxito en combate. El estudio 2 buscó analizar el rendimiento técnico-táctico de los taekwondistas según el género y el éxito en combate. Los participantes fueron deportistas universitarios (estudio 1, N = 86; estudio 2, N = 85) con …

Rapid Weight Loss Alters Handgrip Strength In Greco-Roman Wrestlers

Effects of rapid weight loss (RWL) on handgrip strength (HGS) in combat sports athletes are still quite indefinite. The aim of this study was to delineate the effect of RWL on HGS in Greco-Roman wrestlers. Handgrip strength was measured during three time points. Baseline measurement was carried out before the weight reduction. Second measurement was done after sport specific training combined together with RWL. Finally, third measurement was carried out after sport specific training alone. Results showed that HGS was significantly greater after a training combined with RWL procedure compared to only specific training for one hand. Findings of this study could potentially improve the trainin…

Why do female and male taekwondo athletes win the bout? An analysis based on the Olympic weight category and the result of the bout

2020

Combat sports such as taekwondo, where athletes compete against an opponent require control of technique and tactics, as well as knowing the optimal performance of opponents to win the bout. Therefore, the aim of the present study was to analyse the Olympic competitors (London Olympic Games), according to the weight category (fly, feather, light and heavy) and according to the performance in their fighting (winner vs. loser) in each gender. An observational methodology was used, following a nomothetic, follow-up and multidimensional design of 302 individual performances. The statistical analysis used an ANOVA and T Student test for comparing frequencies. The results obtained indicate signif…

The elite judo female athlete's heart.

2022

Purpose: There is a paucity of data on physiological heart adaptation in elite-level judo female athletes. This study aimed to assess left ventricular morphology and function in highly trained elite female judokas.Methods: The study prospectively included 18 females aged 23.5 ± 2.25 years, nine elite level judokas, and nine healthy non-athlete volunteers. All participants underwent a medical examination, electrocardiogram, and transthoracic 2D echocardiogram. Left ventricular diastolic and systolic diameters and volumes were determined, and parameters of left heart geometry and function (systolic and diastolic) were measured, calculated, and compared between groups.Results: When groups were…

The effects of rapid weight loss on skeletal muscle in judo athletes

2020

Abstract Objective To observe the effect of rapid weight loss (RWL) methods over 3 days on muscle damage in judokas. Methods Eighteen judokas participated in this crossover study, meaning that judo athletes were subjected to exercise-only phase (4 days) and RWL phase (3 days). Subjects were tested for myoglobin, creatine kinase, aldolase, hemoglobin, and hematocrit values on seven consecutive days. These biomarkers served as indicators of acute muscle damage. Results During the exercise-only phase, no significant changes were observed. Myoglobin (Mb) (p < 0.001), creatine kinase (CK) (p < 0.001) and aldolase (ALD) (p < 0.001) significantly increased only during the RWL phase, as we…

Patterns of rapid weight loss in elite sambo athletes

2021

Abstract Background Rapid weight loss (RWL) is commonly practiced in combat sports. Both magnitude and methods used to induce RWL are largely similar among combat sports, but currently, there is no data on RWL methodology used by sambo athletes. Therefore, the aim of this study was to determine RWL procedures sambo athletes apply to lose weight rapidly. Methods The sample consisted of 199 participants, of which 132 males and 67 females who participated in the World Sambo Championship 2020 held in Novi Sad, Serbia. Each participant received RWL questionnaire that was available in multiple languages, and every participant was instructed how to fill it out. Results Almost 87% of sambo particip…

Somatotypes and handgrip strength analysis of elite Serbian sambo athletes

2021

The aim of this study was to establish whether there are differences between weight categories in different anthropometric measurements and handgrip strength between elite Serbian male and female sambo athletes divided into weight categories. A total of 70 elite Serbian sambo athletes participated in the study, who were participants of the World Cadet Sambo Championship held in Novi Sad. Athletes are classified into categories according to gender and official weight categories. Using anthropometry, we calculated somatotypes and hand-grip strength. For statistical analysis, we used a one-way analysis of variance and Tukey’s post hoc tests to compare group differences by weight categories. So…

Isokinetic Profile of Elite Serbian Female Judoists

2021

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

"Successful and feminine athlete" and "natural-born fighter" : a discursive exploration of female judoka's identities in Greece and Finland

2018

Despite feminist concerns about the asymmetrical distribution of power in martial arts and combat sports (MACS), sport psychology research has overlooked issues of inequality and socio-cultural difference, as well as their effects on athletes’ experiences and identity negotiation. The present doctoral dissertation explores the intersection of gender, culture, and identity in judo through the lens of cultural praxis and feminist poststructuralist frameworks. The aim was to explore in what ways the cultural context shapes the experiences and identities of female judoka (judo athletes). Two specific objectives were set: to trace the discourses (systems of knowledge) through which female judoka…
