The Influence of Different Performance Level of Fencers on Simple and Choice Reaction Time

Abstract

-In many sport disciplines reaction time plays a key role in the sport performance. It is good to point out for example ball games or fighting sports (fencing, karate etc.). The research is focused on detection of the differences in the simple and choice reaction time during visual stimulation among elite, sub-elite fencers and beginners. For the measurement a Fitrosword device and the SWORD software were used. An additional stimulus was added during measuring which should increase the overall number of stimuli, but shouldn't force fencer to any reaction whatsoever. The results from presented study can be compared with Hicks law. The next focus of the study was to identify the difference in reaction time during two different movement tasks with different complexity movement requirements. The research was built up on a hypothesis that the results will differ among different performance groups of fencers. The difference however was overt among beginners and elite fencers (p = 0.0088, d = 0.5) in reaction time during different movement tasks (direct hit vs. lunge). The results of this research could be useful to trainers for training process organisation and increase the effectivity of muscle coordination during several movements in fencing.Key words: Fencing; Visual Stimulus; Reaction time; Additional Stimulus; Hicks law.

Flèche versus Lunge as the Optimal Footwork Technique in Fencing

“…Measurements of the bioelectric signal employed a 16-channel EMG system manufactured by Noraxon (DTS, Desktop Direct Transmission System, Noraxon, Scottsdale, ZA, USA) with a sampling accuracy of 16 bits at a frequency of 1500 Hz. The analysis involved the following muscles: Biceps brachii (BB), triceps brachii (LT), flexor carpi ulnaris (FCU), extensor carpi radialis (ECR) on the upper limb holding the weapon, biceps femoris (BF), rectus femoris (RF) on the forward leg, and gastrocnemius as well as caput laterale and caput mediale (GL, GM) on the rear leg [3,11]. The muscle activation assessment applied Ag/AgCl electrodes attached to the subjects’ bodies in accordance with the SENIAM (surface EMG for non-invasive assessment of muscles) procedures.…”

“…It was not until the 1930s that the flèche was introduced by Hungarian fencers and formed an innovative, dynamic solution in the attacks performed on a fencing strip leading to a touch [2]. For this reason, research in the field of biomechanics and motor control often applied the lunge as a diagnostic procedure in the area of comprehensive analysis [3,4,5]. Both touch techniques are fundamentally different in terms of the technique that is followed.…”

An Examination of Adolescent Athletes and Nonathletes on Baseline Neuropsychological Test Scores

“…Some authors have indicated that the skill level of the athlete had no effect on reaction time. For example, Balko et al 25 observed no difference between the reaction times of elite and nonelite fencers. In soccer players, reaction time was not different among elite and nonelite athletes.…”

“…Therefore, these subjects do not need this interhemispheric transfer. The advantage in reaction times is the result of them compared with subjects with ipsilateral dominant eye and responding hand (Azémar et al, 2008;Balkó, 2016;Balkó, Borysiuk, Balkó, & Špulák, 2016). At the same time, the results prove that reaction time of elite and amateur athletes is the same (Balkó, Borysiuk, & Šimonek, 2017;Balkó, Wasik, Chytrý, Dunajová, & Škopek, 2017).…”
