The Use of Computer Based Test Battery for the Assessment of Cognitive Functions in EliteLevel Strength Training The aim of this study was to propose a standard test battery consisting of necessary tools for measuring and comparing the various aspects of cognitive outcomes. The battery was used to determine whether adolescent women performing regular elitelevel strength training differed from their sedentary peers in terms of cognition, and also to determine how a single session of strength training affects cognition in highly trained adolescents. Motor functions, ability of sustaining attention and executive functions of 25 elite female weightlifters and 22 sedentary females were evaluated through finger tapping performance, visual reaction time (VRT) and recognition visual reaction time (RVRT) data. Weightlifters were tested before and after a training session, sedentary controls were tested only during resting. There was a significant increase in mean complex RVRT of weightlifters after training (p 0.05). Total number of taps and mean intertap intervals did not show any difference in the weightlifter group before and after training, also between weightlifters and sedentary controls (pu003e0.05). Elite level strength training does not improve cognition in adolescence. Adolescent weightliftersu0027 executive functions are deteriorated following a single training session however, this effect is temporary.

Identifying a taskinvariant cognitive reserve network using task potency Abstract   Cognitive reserve (CR) is thought to protect against the consequence of age or diseaserelated structural brain changes across multiple cognitive domains. The neural basis of CR may therefore comprise a functional network that is actively involved in many different cognitive processes. To investigate the existence of such a xe2x80x9ctaskinvariantxe2x80x9d CR network, we measured functional connectivity in a cognitively normal sample between 20 and 80 years old (Nxe2x80xafxe2x80xaf265), both at rest and during the performance of 11 separate tasks that aim to capture four latent cognitive abilities (i.e. vocabulary, episodic memory, processing speed, and fluid reasoning). For each individual, we determined the change in functional connectivity from the resting state to each task state, which is referred to as xe2x80x9ctask potencyxe2x80x9d (Chauvin et al., 2018, 2019). Task potency was calculated for each pair among 264 nodes (Power et al., 2012) and then summarized across tasks reflecting the same cognitive ability. Subsequently, we established the correlation between task potency and IQ or education (i.e. CR factors). We identified a set of 57 pairs in which task potency showed significant correlations with IQ, but not education, across all four cognitive abilities. These pairs were included in a principal component analysis, from which we extracted the first component to obtain a latent variable reflecting task potency in this taskinvariant CR network. This task potency variable was associated with better episodic memory (xcexb2xe2x80xafxe2x80xaf0.19, p
