信息量与认知风格对击剑运动员决策速度和准确性的影响 总被引：4，自引：0，他引：4
研究了信息量与决策风格对不同水平和性别的击剑运动员的决策速度和准确性的影响。被试为国家击剑队、江苏省击剑队和江苏省体校的花剑和重剑运动员，以及江苏省现代五项队重剑运动员，共89名。用MANOVA等方法对实验结果进行分析，结果表明，运动水平和信息量是影响击剑运动员决策速度和准确性的主要因素；优秀组花剑和重剑运动员在决策速度上具有绝对优势，不仅远远快于一般水平组运动员，而且也显著快于普通高水平组运动员。信息量主要影响击剑运动员的决策准确性，但对花剑和重剑运动员的影响不一致。认知风格影响花剑运动员的决策准确性，认知风格和性别共同影响重剑运动员的决策速度。提示，决策速度可以作为高级击剑运动员选材的重要指标，也是普通高水平运动员在向优秀级迈进过程中的训练要点。 相似文献

Abstract The aim of this study was to test the effect that changing targets during a simple long lunge attack in fencing exerts on the temporal parameters of the reaction response, the execution speed, and the precision and the coordination of the movement pattern. Thirty fencers with more than 10 years of experience participated in this study. Two force platforms were used to record the horizontal components of the reaction forces and thereby to determine the beginning of the movement. A three-dimensional (3D) system recorded the spatial positions of the 9 markers situated on the fencer plus the epee, while a moving target was projected on a screen, enabling the control of the target change. The results indicated that when a target change is provoked the reaction time (RT), movement time (MT), and the time used in the acceleration phase of the centre of mass (CM) increases significantly with respect to the attack executed with a straight thrust. The speed and horizontal distance reached by the CM at the end of the acceleration phase (VX(CM) and SX(CM), respectively) significantly decreased, while the errors increased. However, the temporal sequence of the movement pattern did not appreciably change. 相似文献

Abstract The aim of the present work is to examine the differences between two groups of fencers with different levels of competition, elite and medium level. The timing parameters of the response reaction have been compared together with the kinetic variables which determine the sequence of segmented participation used during the lunge with a change in target during movement. A total of 30 male sword fencers participated, 13 elite and 17 medium level. Two force platforms recorded the horizontal component of the force and the start of the movement. One system filmed the movement in 3D, recording the spatial positions of 11 markers, while another system projected a mobile target over a screen. For synchronisation, an electronic signal enabled all the systems to be started simultaneously. Among the timing parameters of the reaction response, the choice reaction time (CRT) to the target change during the lunge was measured. The results revealed differences between the groups regarding the flight time, horizontal velocity at the end of the acceleration phase, and the length of the lunge, these being higher for the elite group, as well as other variables related to the temporal sequence of movement. No significant differences have been found in the simple reaction time or in CRT. According to the literature, the CRT appears to improve with sports practice, although this factor did not differentiate the elite from medium-level fencers. The coordination of fencing movements, that is, the right technique, constitutes a factor that differentiates elite fencers from medium-level ones. 相似文献

This study investigated the impact that mouth rinsing carbohydrate solution has on skill-specific performance and reaction time following a fatigue-inducing bout of fencing in epee fencers. Nine healthy, national-level epee fencers visited a laboratory on two occasions, separated by a minimum of five days, to complete a 1-minute lunge test and Stroop test pre- and post-fatigue. Heart rate and ratings of perceived exertion (RPE) were recorded during completion of the fatiguing protocol. Between fights the participant’s mouth rinsed for 10?seconds, either 25?ml of 6.7% maltodextrin solution (MALT) or water (PLAC). Blood lactate and glucose were recorded at baseline, pre- and post-testing. Results showed an increase in heart rate and overall RPE over time in both conditions. There were no differences in blood glucose (F(1,8)?=?.63, P?=?.4, ηp?=?.07) or blood lactate levels (F(1,8)?=?.12, P?=?.70, ηp?=?.01) between conditions as a function of time. There was a significant improvement in lunge test accuracy during the MALT trial (F(1,8)?=?5.21, P?=?.05, ηp?=?.40) with an increase from pre (81.2?±?8.3%) to post (87.6?±?9.4%), whereas there was no significant change during the placebo (pre 82.1?±?8.8%, post 78.8?±?6.4%). There were no recorded differences between conditions in response time to congruent (F(1,8)?=?.33, P?=?.58, ηp?=?.04) or incongruent stimuli (F(1,8)?=?.19, P?=?.68, ηp?=?.02). The study indicates that when fatigued mouth rinsing MALT significantly improves accuracy of skill-specific fencing performance but no corresponding influence on reaction time was observed. 相似文献

The aim of this study was to analyse the effect of stimulus change timing on reaction response time parameters, horizontal velocity of the centre of mass (CM) and precision during offensive actions in fencing. Twelve fencers from the Spanish National Foil Team were included in the study. Two 500 Hz force plates were used to register the horizontal component of the reaction force while a 3D video camera set at 250 Hz recorded the spatial position of 11 body markers and a projector connected to a programmed stopwatch projected a moving target (stimulus) on a screen. When the circle (target) appeared in the centre of the plastron, fencers had to execute a step-forward-lunge as fast as possible, trying to touch the circle with the tip of the foil. During the lunge, the position of the target could randomly shift or not to three different positions. The stimulus change was performed randomly at four different times with a progressive delay. The results show that target changes did not have any effect when they occurred at the beginning of the movement sequence. However, when the target change was delayed, reaction and movement times increased and the technical execution of the lunge changed, leading to more errors. 相似文献

For fencing, speed of the lunge is considered critical to success. The aim of this study is to investigate determinants of lunge speed based on biomechanics. Ground reaction force (GRF) and three-dimensional kinematic data were collected from 7 elite fencers and 12 intermediate-level fencers performing maximum-effort lunges. The results showed that elite fencers acquired a higher horizontal peak velocity of the centre of gravity (HPV) and concomitantly a higher horizontal peak GRF exerted by rear leg (PGRF) than intermediate-level fencers (P?P?P?P?≤?.05). Our findings suggest that training aimed at enhancing strength and power of rear knee extensors is important for fencers to improve speed of the lunge. Also, increasing the extension of rear knee during the lunge, at the same time decreasing the flexion of the forward knee before extension are positive for lunge performance. 相似文献

Abstract We examined the extent to which attributions are consistent in the days following competition and how attributions made immediately after competition may influence the temporal patterning of emotions experienced in response to competition. A sample of 60 adult female golfers completed measures of performance satisfaction, causal attribution, and emotion immediately after competition, 5 h after competition, and 2 days after competition. Repeated-measures multivariate analysis of covariance indicated that attributions did not change over this period. Emotions showed a significant decrease in intensity over the 5-h post-competition period. Regression analyses indicated that changes in anger and dejection were more likely in the case of less successful performances. For anger, attributions moderated this level of change. Golfers experienced anger for a longer period when they identified the cause of poor performance as stable rather than unstable. Thus, in the present sample although attributions did not change over 2 days, the longevity of anger depended on the attributions made immediately after competition. 相似文献

Abstract Thirty national level female fencers were studied with the Cattell 16 Personality Factor Questionnaire and the Edwards Personal Preference Study to determine if there were distinct personality traits characteristic of champion level female fencers and if there was any correlation between personality traits and level of achievement in the 1968 National Championship. A definite fencer's personality emerged when they were compared with the national norms. In general, the competitive fencer may he described as a very reserved, self-sufficient, autonomous individual with a below-average desire for affiliation and nurturance. She has a strong need to be the very best and is an intelligent, creative, experimenting, and imaginative person. She also tends to be assertive and aggressive. An analysis of variance revealed that only one personality factor would differentiate levels of achievement. The top level competitor was significantly more dominating than the low level competitor. 相似文献
