- The current investigation examined the potential teleoanticipatory effect on perceptual response during repeated bouts of maximal sprint work. To determine the consistency of ratings of perceived exertion (RPE) increase during identical exercise bouts following variable recovery periods, 16 (8 men, 8 women) participants completed four separate trials of repeated maximal sprinting on 4 separate days utilizing different recovery periods. Following completion of the baseline trial, participants were given variable, counter-balanced recovery periods of 24, 48 and 72 hours, whereupon they repeated the intermittent exercise protocol. To determine the degree of similarity among trials, each individual's rate of RPE progression during each cycle of eight sprints throughout the recovery trials were compared to the rate of progression during the baseline exercise session. A series of 4 (trial) x 3 (cycle of sprints) repeated measures ANOVA were performed to identify significant main effects between trials and among cycles while session RPE was analyzed using one-way repeated measures ANOVA. Fisher's least significant difference post-hoc procedures were performed to identify where significant differences occurred when appropriate. Results revealed an inconsistency in the stability of RPE across repeated bouts of sprint exercise, with at least 50% of individuals having a substantial difference in RPE (i.e. +/- 1 unit change) in at least one subsequent trial. These variations in perceptual responses were observed despite a concomitant stability of physiological and performance responses between sessions. Results suggest that rate of RPE increase correspond more closely to increased or decreased physiologic strain than to an anticipatory, feed-forward mechanism following variable recovery durations.

- The holistic concept of physical literacy (PL) embraces different person-centered qualities (physical, cognitive, affective/psychological) necessary to lead physically active lifestyles. PL has recently gained increasing attention globally and Europe is no exception. However, scientific endeavors summarizing the current state of PL in Europe are lacking. Therefore, the goal of this study was to comprehensively assess and compare the implementation of PL in research, policy, and practice across the continent. We assembled a panel of experts representing 25 European countries. Employing a complementary mixed-methods design, the experts first prepared reviews about the current state of PL in their countries (categories: research, practice/policy). The reviews underwent comparative document analysis ensuring a transnational foureyes principle. For re-validation purposes, the representatives completed a quantitative survey with questions reflecting the inductive themes from the document analysis. The document analysis resulted in ten disjunct themes (related to “concept”, “research”, “practice/policy”, “future/prospect”) and yielded a heterogenous PL situation in Europe. The implementation state was strongly linked to conceptual discussions (e.g., existence of competing approaches), linguistic issues (e.g., translations), and country-specific traditions. Despite growing scholarly attention, PL hesitantly permeates practice and policy in most countries. Nevertheless, the experts largely anticipate increasing popularity of PL for the future. Despite the heterogeneous situation across Europe, the analysis has uncovered similarities among the countries, such as the presence of established yet not identical concept. Research should intensify academic activities (conceptuallinguistic elaborations, empirical work) before PL may gain further access into practical and political spheres in the long term.
