The relative contribution of training intensity and duration to daily measures of training load in professional rugby league and union

ABSTRACT

This study examined the relative contribution of exercise duration and intensity to team-sport athlete’s training load. Male, professional rugby league (n = 10) and union (n = 22) players were monitored over 6- and 52-week training periods, respectively. Whole-session (load) and per-minute (intensity) metrics were monitored (league: session rating of perceived exertion training load [sRPE-TL], individualised training impulse, total distance, BodyLoad?; union: sRPE-TL, total distance, high-speed running distance, PlayerLoad?). Separate principal component analyses were conducted on the load and intensity measures to consolidate raw data into principal components (PC, k = 4). The first load PC captured 70% and 74% of the total variance in the rugby league and rugby union datasets, respectively. Multiple linear regression subsequently revealed that session duration explained 73% and 57% of the variance in first load PC, respectively, while the four intensity PCs explained an additional 24% and 34%, respectively. Across two professional rugby training programmes, the majority of the variability in training load measures was explained by session duration (~60–70%), while a smaller proportion was explained by session intensity (~30%). When modelling the training load, training intensity and duration should be disaggregated to better account for their between-session variability.     

Critical Review of Mary Midgley's Intelligent Design Theory and Other Ideological Problems

Mary Midgley's pamphlet Intelligent Design Theory and Other Ideological Problems has been a widely read contribution to discussions of the place of creationism in schools. In this critique of her account, I outline Midgley's view of the relations between science and religion, her claims about what material can legitimately appear in science lessons, and her account of the nature of religion. I argue that she is mistaken in all three areas, and show that her most plausible reply to these criticisms also fails. Finally, I offer some thoughts on the proper relations between science and religion in the classroom.     

Evaluating Student Success in a Cohort-based Graduate Program for Criminal Justice Professionals

Previous studies have shown that additional education for criminal justice professionals can improve individual effectiveness. This higher level of education can facilitate better communication, problem-solving skills, and performance. The University of South Florida offers a unique cohort-style/weekend-based Master’s program (MACJA) that is designed specifically for these professionals. This program has graduated 180 students since 2006, all members of the criminal justice field. The current study aims to determine which student background factors are associated with a higher graduating GPA in the program. This project will also discuss the results of a follow-up survey of MACJA graduates assessing professional advancement following graduation, specifically targeting topics such as promotions, special awards or recognitions, teaching experience, and further education.     

Outside the library: Early career researchers and use of alternative information sources in pandemic times

Presents findings from a study into the attitudes and practices of pandemic-era early career researchers (ECRs) in regard to obtaining access to the formally published scholarly literature, which focused on alternative providers, notably ResearchGate and Sci-Hub. The study is a part of the Harbingers project that has been exploring the work lives and scholarly communication practices of ECRs in pre-pandemic times and during the pandemic, and utilizes data from two rounds of interviews with around 170 ECRs from the sciences and social sciences in eight countries. Findings show that alternative providers, as represented by ResearchGate and Sci-Hub, have become established and appear to be gaining ground. However, there are considerable country- and discipline-associated differences. ECRs' country-specific level of usage of the alternative providers is partly traceable to the adequacy of library provisions, although there are other factors at play in shaping ECRs' attitudes and practices, most notably convenience and time saving, as well as the fact that these platforms have become embedded in the scholarly dashboard. There is a dearth of evidence of the impact of the pandemic on ECRs' ways of obtaining scholarly papers.
