Abstract

The purpose of this study was to investigate the effects of three simulated goalball games on neuromuscular, physiological, perceptual, and technical parameters. Ten male players underwent assessments before and immediately after each game. Heart rate was recorded at rest and during all games that were entirely filmed for further technical performance analysis. Exercise significantly decreased knee extensor muscles peak force and percentage of voluntary activation after the second and third games, indicating the presence of central fatigue. Heart rate responses remained predominantly in a range equivalent to moderate activity intensity in all games. In addition, perceptual parameters were associated with reduced frequency of throws and density of actions. These findings suggest significant implications for the management of physical training, game strategy during a competition, and fixture change from three to two games per day.

一天内三场模拟球类比赛会引起中枢疲劳，影响比赛技术表现。

本研究的目的是探讨三种模拟球类运动对神经肌肉、生理、知觉和技术参数的影响。10名男性球员在每场比赛之前和之后都接受了评估。为了进一步的技术性能分析，我们记录了休息时和所有比赛期间的心率。在第二场和第三场比赛后，运动显著降低了膝关节伸肌的峰值力量和自愿激活的百分比，表明中枢疲劳的存在。在所有游戏中，心率反应主要保持在中等活动强度的范围内。此外，知觉参数与减少投掷频率和动作密度有关。这些发现对体育训练的管理、比赛中的比赛策略以及每天三场到两场比赛的赛程变化具有重要意义。

期刊介绍： APAQ is an international, peer-reviewed, multidisciplinary journal designed to stimulate and communicate scholarly inquiry relating to physical activity that is adapted in order to enable and enhance performance and participation in people with disability. Physical activity implies fine, gross, functional, and interpretive movement including physical education, recreation, exercise, sport, and dance. The focus of adaptation may be the activity or task that is to be performed, environment and facilities, equipment, instructional methodology, and/or rules governing the performance setting. Among the populations considered are persons with motor, intellectual, sensory, and mental or other disabilities across the life span. Disciplines from which scholarship to this aim may originate include, but are not limited to, physical education, teacher preparation, human development, motor behavior and learning, biomechanics, exercise and sport physiology, and exercise and sport psychology. Scientific inquiry may originate from quantitative or qualitative inquiry, as well as from multimethod designs.
