“…Research studies have revealed different factors that can affect the effectiveness of perceptual-motor learning and performance, including task difficulty [9,10], attention [11,12], and memory abilities [13]. Moreover, stress and anxiety have been shown to decrease motor performance during the early stages of learning, but have no effect (or may even improve performance) during later learning stages [14,15]. Furthermore, Hordacre et al [16] reported perceptual-motor learning benefits during a pinch task following increased stress and anxiety induced by the mental arithmetic task.…”

Purpose: Physical exercise has been shown to exert various effects on visuomotor processing and motor learning. The present study aimed to examine the impact of exercise with progressively increased physical load on consecutive stages of perceptual-motor learning. We compared the effectiveness of visuomotor adaptability in four subsequent trials during a complex coordination task performed in different conditions, including under conditions of progressively increased physical load, and in non-exercise resting control conditions. Material: Twenty-seven physical education university students participated in this study. Participants were randomly assigned to one of two group: (1) an exercise experimental group (n = 14), or (2) a non-exercise resting control group (n = 13). Methods: Participants in the experimental group performed three 10-minute effort-tests with increasing intensity on a cycloergometer. Each participant was assigned individual workload values below the lactate threshold (40% VO2max), at the lactate threshold (60% VO2max), and above the lactate threshold (80% VO2max). Four sessions of the two-hand coordination test included in the Vienna Test System were used to examine visuomotor adaptability variation. The total time duration, total error duration, and coordination difficulty were analyzed. Results: There was a significant interaction between number of test repetitions and group (experimental, control) for total duration ( F (3,75) = 3.54, p = 0.018). In particular, there was a significant reduction ( p = 0.006) in duration in the control group after fourth test repetitions as compared to the baseline. In the experimental group, in contrast, there was a tendency for duration to increase after exercise above the lactate threshold intensity. There was also a significant interaction between test repetitions and group for total error duration ( F (3,75) = 3.14, p = 0.03). Conclusions: The results suggest that high intensity exercise can disrupt visuomotor processing during complex skill acquisition. These findings highlight the interplay between exercise intensity and motor control and learning, which in turn, has practical implications for developing and improving motor training and physical education programs.

Introduction: The purpose of the study was to analyze the psychophysiological characteristics of football players and water sports athletes as factors of professional selection. Materials and methods: The study involved students of a specialized sports school (n = 31, age: 16-17 years). The participants were divided into two groups: group 1 – 20 football players, group 2 – 11 water sports athletes (swimming). The level of sportsmanship is 1 category, Candidates and Masters of Sports. Tests applied: determination of the duration of an individual minute (IM), measuring of a 10 cm segment (SM), determination of simple hand-eye coordination (SHEyC), and simple hand-ear coordination (SHEaC), the technique of “Figures memorizing”, solution of 10 sums. Results: The results of the IM test reflect the prevalence of the earlier test completion. All participants indicated a lower value in 9th test of a segment measuring. The results of the SHEyC and SHEaC of the participants were similar. The results of all tests were less than 10 in the test of “Figures memorizing”. Football players revealed link between coordination and psychophysiological tests results, while swimmers revealed link between coordination and sensory type of tests. Conclusions: The carried out psychophysiological analysis of athletes’ condition of team sports and water sports confirmed the possibility of applying these tests for selection. The results obtained reflect the specific influence of the sport on the athletes’ bodies. These indicators demonstrate the increased requirements for spatial orientation, the importance of reaction to auditory stimuli and the increased ability of football players to control the surrounding space and control the game situation.
