    Input: Research on inattentional blindness shows that individuals fail to notice unexpected objects or events when attention is focused elsewhere . The majority of previous studies on inattentional blindness have been performed at rest , even though there are several real-life situations that require both physical exercise and focus of attention to accomplish a particular task . A number of different studies have demonstrated that physical exercise influences cognitive performance and attention processes in a variety of ways . Relatively little is known about the effects of physical load on inattentional blindness . The present study was the first attempt to investigate inattentional blindness effects as a function of physical load . Participants were r and omly assigned to three groups where they performed two different  inattentional blindness tasks : at rest ( group 1 ) and on a bicycle ergometer under moderate ( group 2 ) or high ( group 3 ) physical exercise . The results showed a decrease of inattentional blindness effects from the resting to the moderate exercise condition , and then an increase for the high physical exercise condition , representing an inverted-U plot . Findings support the notion that physical exercise influences individuals ' attention performance . We concluded that moderate physical exercise has a positive impact on inattentional blindness , given that people under moderate  physical exercise more frequently notice an unexpected object when attention is diverted to another task , and that this evidence should be taken into account when considering certain real-life events Two experiments were carried out to examine the effect of moderate and maximal exercise on the cognitive performance of experienced soccer players . Experiment 1 examined the speed and visual search in familiar ( game ) and unfamiliar ( non-game ) context s. Participants had to detect , as quickly as possible , the presence or absence of a ball in tachistoscopically presented slides . Participants were tested at rest and while exercising at 70 and 100 % maximum power output . A main effect of exercise intensity was demonstrated and Tukey post-hoc tests showed that performance during maximal exercise was significantly better than in the other two conditions . We concluded that exercise significantly improves speed of visual search . Experiment 2 examined the effects of exercise on speed of search , speed of decision following ball detection , overall speed of decision and accuracy of decision at rest and while exercising at 70 and 100 % maximum power output . A repeated- measures multivariate analysis of variance and Tukey post-hoc tests showed that performance during exercise was significantly better than at rest . Observation of the separate univariate analyses of variance demonstrated that most of the variance could be accounted for by overall speed of decision and speed of decision after ball detection . We concluded that exercise induces not only an improvement in a simple task , like speed of visual search , but also an overall increase in speed of information processing . Theories concerning the effect of emotionally induced arousal on cognitive performance do not accurately predict the effect of physically induced arousal on cognitive tasks 
    Output:
    
Results suggested the impact of  acute physical exercise on perceptual-cognitive performances of athletes depends on the specificity of the induced exercise and perceptual-cognitive task .
Additionally , speed and accuracy were influenced differently by physical exercise .
Furthermore , skilled athletes seem to be more positively influenced by acute physical exercise than novices .
