“…So far researchers have mainly focused on investigating visual evoked potentials in groups of athletes and untrained individuals. The differences found for the parameters of the visual evoked potentials between professional athletes and non-athletes have indicated that adaptations of the visual functions in sports requiring rapid detection of and response to visual stimuli are possible [1,8,9,12]. The results of studies carried out by other authors have confirmed the influence of long-term sports training characterised by a high degree of involvement of perceptual functions on neuroanatomical changes in the brains of athletes practising different sports disciplines.…”

“…The research by Thomas et al [7] showed that cricket players had a shorter N75 wave latency than untrained subjects, whereas Delpont et al [8] observed a shorter latency of P100 waves in tennis and squash players compared to rowers and control subjects. Similar results were obtained in studies involving athletes practising such sports as volleyball [9,10], fencing [11], and karate [12]. These findings suggest that practising sports which are fastpaced and require accurate and rapid responses to visual stimuli can have a greater impact on the effectiveness of visual processing compared to undertaking other forms of sports training.…”

“…Likewise, Özmerdivenli et al [9] found a significantly lower amplitude and shorter latency of the N145 wave of visual evoked potentials in volleyball players compared with untrained subjects. The results obtained in the current study revealed similar relationships in the group of rowers with respect to the peripheral location (for monocular and binocular viewing) and boxers (for the dominant eye in the central location).…”

Introduction. Gaining insight into the mechanisms and scope of possible adaptations of visual functions to the conditions determined by the demands imposed by sports training seems to be very interesting not only from a cognitive point of view, but also with respect to the practical applications of the findings of such investigations in the training process. The aim of the study was to assess the function of early visual processing in athletes representing different sports disciplines with varying training experience. Material and methods. The study involved 95 athletes practising football (n = 24), volleyball (n = 22), boxing (n = 26), and rowing (n = 23). The bioelectric function of the visual pathway was assessed based on recordings of visual evoked potentials (VEPs). The regions which were stimulated were the peripheral and central areas of the retina. During the test, we recorded the amplitude (µV) and latency (ms) of the P100 component of the VEP waveform for both monocular stimulation (for the dominant and non-dominant eye) and binocular stimulation. Results. Lower VEP P100 amplitude values were found for the peripheral and central locations for monocular and binocular viewing in more experienced volleyball players and rowers (p < 0.05). In the case of boxers with greater training experience, a significantly lower (p < 0.05) amplitude of the VEP P100 wave was observed in the central location in the dominant eye. However, we did not find significant differences (p > 0.05) in intragroup variability in VEP P100 latency in relation to training experience in any of the sports disciplines examined. Conclusions. Training experience has an influence on the early stage of sensory processing with respect to neural activity. Training experience has been found to differentiate athletes in terms of the temporal parameters of the visual evoked potentials recorded in the current study only to a limited extent.

“…Increased neural efficiency (i.e., performing the same work with less cortical effort) has been demonstrated in athletes using electrophysiological techniques. However, the reverse effect has been reported for sensory stimuli processing (Murakami et al, 2008;Ö zmerdivenli et al 2005), and when attention and motor inhibition are required . These data can be interpreted as adaptive changes consequent to sports activity.…”

We investigated the effect of sports activity on physically-disabled individuals using behavioral and electrophysiological techniques. Visual go/no-go discriminative and simple response tasks were used. Participants included 17 disabled athletes, 9 from open-skill (wheelchair basketball) and eight from closed-skill (swimming) sports, and 18 healthy non-athletes. Reaction times of the disabled athletes were slower than those of healthy non-athletes on both tasks (7% and 13% difference, respectively). Intra-individual variations in reaction times, switch cost, and number of false alarms, were higher in the swimmers, but comparable to healthy non-athletes, in the basketball group. Event-related potentials (ERPs) early components P1, N1, and P2 had longer latencies in the disabled athletes. The late P3 component had longer latency and smaller amplitude in the disabled athletes only in the discriminative response task. The N2 component, which reflected inhibition/execution processing in the discriminative response task, was delayed and reduced in the swimmer group, but was comparable to healthy subjects in the basketball group. Our results show that (1) the ERP components related to perceptual processing, and late components related to executive processing, were impaired in disabled subjects; and (2) open-skill sports such as basketball may partially compensate for executive control impairment by fostering the stability of motor responses and favoring response flexibility.

“…Previous studies have revealed shortened VEP latencies in trained subjects compared to sedentary subjects (Ozkaya et al 2003;Ozmerdivenli et al 2005). Delpont et al (1997) found shortened patterned reversal visual evoked potential (PREP) latencies in a group of tennis players but found that they were unaltered in rowers compared to control subjects.…”

Visual evoked potentials (VEP) can be used as an objective non-invasive method to study the electrical activity of the visual system. Latency and amplitude measurements of VEP demonstrated that diabetes mellitus has been associated with increases in the latencies whereas the amplitude measurements revealed contradictory results. Although physical exercise has been reported to reduce the complications of diabetes mellitus, the effect of exercise on the visual system remains unknown. We investigated the effects of long-term moderate physical exercise on VEP in streptozotocin (STZ)-diabetic rats. We also measured brain thiobarbituric acid-reactive substances (TBARS) to explore the possible contribution of lipid peroxidation on the visual system. Animals were divided into four groups: control (C), control exercise (CE), diabetic (D) and diabetic exercise (DE) groups. Diabetes was induced by a single intraperitoneal injection of STZ (60 mg/kg). Three days after the confi rmation of diabetes, DE and CE groups were trained by running on a motor-driven treadmill with a progressive eightweek programme. The animals began running at 10 m/min, 0° slope, 10 min/day and reached a level of 28 m/min, 6° slope, 60 min/day by week 8. TBARS were elevated and VEP latencies were delayed in diabetic rats, indicating diabetes-induced defects in the optic pathway. These prolonged latencies were restored by exercise training. VEP amplitudes of the DE group were found unaltered with the exception of a decrement in P 2 N 2 which represents an early component of VEP, suggesting that exercise improves visual system defects in diabetic animals at different levels of the optic pathway. diabetes mellitus; visual evoked potentials; exercise; lipid peroxidation; rat © 2007 Tohoku University Medical PressPhysical exercise is well known to have many benefi cial effects on human health. Recently, attention has largely focused on the increase of free radicals generated during exercise, especially during aerobic activities. This increase is related to the elevation of electron transport fl ux, mitochondrial oxygen consumption, energy demand, oxygen supply and body
