The archaeological excavation of ‘Piazza Bovio’ at Naples has yielded a large deposit, characterized by exceptional findings relating to the production of a glass workshop dated to the sixth to seventh centuries ad. The workshop features, coupled with the presence of broken glass for recycling and abundant glass scrap, leads us to identify the area as part of a secondary workshop. Selected finished objects and glass scraps were characterized by SEM/EDS and LA–ICP–MS and compared with major compositional groups of glass recognized in the western Mediterranean during the first millennium ad. The aim is to verify the hypothesis of a secondary production in Naples, using raw glass from the Levant area. Three different natron groups were identified on the basis of the colour and the chemical composition. The naturally coloured (blue–green) group is consistent with Levantine I glass. The yellow–green group is associated with HIMT glass, while the colourless glass was produced with different raw materials and probably in another specialized workshop. [ABSTRACT FROM AUTHOR]

Objective: Although some scientific information on electronic body protectors in taekwondo is available, no research has been done to assess the impact of kicks in a competitive situation. The purpose of this study, then, was to assess the energy absorbed by these protectors from kicks performed in an actual taekwondo competition. Methods: Subjects consisted of junior (14-17 years) and senior (?18 years) male taekwondo-in, who participated in an open tournament. Data on the energy imparted by valid kicks in Joules (J) were collected from a public visual electronic monitor. Results: Energy was higher for the seniors: 264.31 ± 56.63 J versus 224.38 ± 48.23 J for the juniors (eta2 = 0.121). The seniors scored lower in percent impact but the effect was trivial: 123.46 ± 24.77% versus 136.70 ± 26.33% (eta2 = 0.087). Conclusions: The difference between senior and junior taekwondo-in in absolute energy generated was small, while the difference in relative energy impact was trivial in favour of the junior taekwondo athletes.

The aim of this study was to compare the acute effects of the Running Anaerobic-based Sprint Test (RAST) with different loads in physiologic and neuromuscular parameters. 12 amateur rugby union players performed the RAST, with heart rate (HR) and blood lactate concentration ([LAC]) measurements pre, post and 5 min post RAST, squat jump (SJ), countermovement jump (CMJ), 10 m (S10) and 20 m (S20) sprints pre and post RAST. These procedures were carried out during three sessions, randomly performed in different conditions: no load (NL), load with 13% (L13) or 25% (L25) of body mass. Between loads, peak power in RAST and mean power were statistically different, with lower in L25 condition. Between moments, significant differences were observed with decrease in HR, increase in [LAC] for pre, post and 5 min post, respectively, and performance decrease in CMJ and S10, without load vs moment interaction. In addition, between loads, with exception of power produced in RAST, no significant differences were observed for any variable. Therefore, despite the differences in power production during RAST, it is concluded that RAST performed with or without loads of either 13 or 25% of body mass induces similar acute effects in both physiologic and neuromuscular parameters.
