PHYSICAL ACTIVITY LEVEL DOES NOT INFLUENCE THE NEUROMUSCULAR FATIGUE IN ADULTS

Introduction: Fatigue during voluntary muscle contractions is a complex and multifactorial phenomenon associated with central changes and adaptations of the neuromuscular system. Objective: The purpose of this study was to evaluate the fatigue induced by intermittent successive extension of the knee between active and inactive university students. Method: Twenty healthy men (≥18 years), voluntarily participated in this study. To determine the maximum voluntary isometric contraction (MVIC) of the knee extensors muscle group, three sets of isometric contractions of knee extension were performed for five seconds with five minutes of rest between sets. The fatigue protocol consisted of 10 sets of 10 maximal concentric contractions of the extensor on the right knee, performed at 75% of MVIC with an interval of 45". Results: Significant reductions were observed (p<0.01), both in isometric strength (-34±4%) and the dynamic strength (-40 ± 3%). In addition, the slope of relationship strength x repetition was -0.79±0.07 Nm/repetitions and the magnitude of the effect reached -8.90. Conclusion: The protocol was useful to induce peripheral fatigue, although muscle strength is greater in the active group. In both isometric and dynamic action, muscle fatigue did not differ between groups

Put It in Your Shoe It Will Make You Limp: British Men’s Online Responses to a Male Pill

The file attached to this record is the author's final peer reviewed version. The Publisher's final version can be found by following the DOI link.This article analyzes online interactions between British men and other online readers’ comments in response to two news articles focused on a male contraceptive pill. The aim of the study was to explore how British men’s online accounts construct a male pill as a potential contraceptive option for family planning. The two online articles reported the scientific innovations, as well as the production and marketing, of a nonhormonal, plant-based pill for men. Discourse analysis was used to analyze the online comments, from which two discourses emerged: (a) “Men as responsible health consumers” and (b) “‘Killing sperm’ and other side effects on semen.” When provided with the opportunity to take future responsibility for family planning, male readers were found to be unlikely to use a contraceptive pill. The men expressed the need for new options of contraception but, overall, felt a male pill was not the solution

Liv og død i Hierapolis Norske utgravninger i en hellenistisk–romersk–bysantinsk by i Lilleasia

Life and Death at Hierapolis. Norwegian excavations in a Hellenistic–Roman–Byzantine town in Asia Minor From 2007 to 2015 the University of Oslo, invited by The Italian Archaeological Mission at Hierapolis in Phrygia, conducted archaeological research in the North-East Necropolis at Hierapolis. The aim of the project was to document all visible tombs and sarcophagi of the necropolis and excavate selected tomb areas and tombs. The research, including osteological, DNA- and isotope-analyses, investigated the life of the inhabitants over a long period of time (ca. 100–1300 A.C.) with reference to tomb architecture, landscape perception, organization, entrepreneurship, ritual practices, genetic relations and origins, demography, health, sickness, diets, and individual movement patterns. Many of the aims are answered in the article, here shall only be mentioned two important discoveries: cremation has been documented as late as the 5th/6th centuries A.C., in periods of crisis perhaps used to signal pagan opposition to imposed Christian practices; the life conditions in the Roman/Early Byzantine period were much better than in that of the Middle Byzantine period.
