No full textEffects of a Cognitive-Motor Training on Anticipatory Brain Functions and Sport Performance in Semi-Elite Basketball Players
No full textThe aim of this research was to test the possible effects of cognitive–motor training (CMT) on athletes’ sport performance and cognitive functions. Namely, specific athletic tests, brain processes associated with anticipatory event-related potential (ERP) components and behavioral performance during a cognitive discrimination response task were evaluated pre-and post-training. Twenty-four young semi-professional basketball players were recruited for the study and randomly divided into an experimental (Exp) group executing the CMT training and a control (Con) group performing standard motor training. The CMT training protocol included exercises in which participants performed cognitive tasks during dribbling exercises using interactive devices which emitted visual and auditory stimuli, in which athletes’ responses were recorded. Results showed that following training, only the Exp group improved in all sport-specific tests (17%) and more than the Con group (88% vs. 60%) in response accuracy during the cognitive test. At brain level, posttraining anticipatory cognitive processes associated with proactive inhibition and top-down attention in the prefrontal cortex were earlier and heightened in the Exp group. Our findings confirm previous studies on clear improved efficacy of CMT training protocols on sport performance and cognition compared to training based on motor exercises only, but extend the literature in showing that these effects might be explained by enhanced anticipatory brain processing in the prefrontal cortex. The present study also suggests that in order to achieve specific athletic goals, the brain adapts cognitive functions by means of neuroplasticity processes
Temporal variations in the diversity of airborne fungal spores in a Mediterranean high altitude site
No full textRelationships between meteorological factors and airborne fungal spore concentrations at high altitudes are virtually unknown. We used cross-correlation analyses to test the relationships between daily variation in meteorological factors (i.e., temperature, humidity and wind speed) and airborne spore concentration, diversity (Shannon and Simpson indices) and evenness (Pielou index) in an Apennine high altitude site (Gran Sasso Massif, 2117 m elevation). Daily average concentration of spores in this high altitude site was much lower than that observed at a low altitude site in the same area, which can be explained by the environmental conditions at high altitudes. We found that diversity and evenness tended to be negatively correlated with temperature and positively with humidity and wind speed with some delay, whereas abundance tended to be positively correlated with temperature and wind, but negatively with humidity. These relationships can be explained by the fact that rain increases turnover by removing dry spores of Cladosporium (the most abundant taxon) and aerosolizing wet ones. The high dominance of the most abundant taxon is a reflection of the extreme climatic conditions at high altitudes
