Twenty-four female footballers (14.9 ± 0.9 year) performed unanticipated cutting maneuvers in a laboratory setting and on the football pitch during football-specific exercises (F-EX) and games (F-GAME). Knee joint moments were collected in the laboratory and grouped using hierarchical agglomerative clustering. The clusters were used to investigate the kinematics collected on field through wearable sensors. Three clusters emerged: Cluster 1 presented the lowest knee moments; Cluster 2 presented high knee extension but low knee abduction and rotation moments; Cluster 3 presented the highest knee abduction, extension, and external rotation moments. In F-EX, greater knee abduction angles were found in Cluster 2 and 3 compared to Cluster 1 (p = 0.007). Cluster 2 showed the lowest knee and hip flexion angles (p < 0.013). Cluster 3 showed the greatest hip external rotation angles (p = 0.006). In F-GAME, Cluster 3 presented the greatest knee external rotation and lowest knee flexion angles (p = 0.003).

To meet the potential that exergames hold, they need to be adapted to the individual abilities of the player and their training objectives. Therefore, it is important to know whether and how game characteristics affect their playing. The aim of this study is to investigate the effect of two different kinds of exergame (step game and balance game) played at two difficulty levels on brain activity and physical activity.MethodsTwenty-eight older independently living adults played two different exergames at two difficulty levels each. In addition, the same movements as during gaming (leaning sideways with feet in place and stepping sideways) were performed as reference movements. Brain activity was recorded using a 64-channel EEG system to assess brain activity, while physical activity was recorded using an accelerometer at the lower back and a heart rate sensor. Source-space analysis was applied to analyze the power spectral density in theta (4 Hz–7 Hz) and alpha-2 (10 Hz–12 Hz) frequency bands. Vector magnitude was applied to the acceleration data.ResultsFriedman ANOVA revealed significantly higher theta power for the exergaming conditions compared to the reference movement for both games. Alpha-2 power showed a more diverse pattern which might be attributed to task-specific conditions. Acceleration decreased significantly from the reference movement to the easy condition to the hard condition for both games.DiscussionThe results indicate that exergaming increases frontal theta activity irrespective of type of game or difficulty level, while physical activity decreases with increasing difficulty level. Heart rate was found to be an inappropriate measure in this population older adults. These findings contribute to understanding of how game characteristics affect physical and cognitive activity and consequently need to be taken into account when choosing appropriate games and game settings for exergame interventions.}}, author = {{Müller, Helen Martha and Baumeister, Jochen and Bardal, Ellen Marie and Vereijken, Beatrix and Skjæret-Maroni, Nina}}, issn = {{1663-4365}}, journal = {{Frontiers in Aging Neuroscience}}, keywords = {{Cognitive Neuroscience, Aging}}, publisher = {{Frontiers Media SA}}, title = {{{Exergaming in older adults: the effects of game characteristics on brain activity and physical activity}}}, doi = {{10.3389/fnagi.2023.1143859}}, volume = {{15}}, year = {{2023}}, } @article{43092, abstract = {{By using coordinating anions such as acetate, a water-in-salt-like coordination environment of Zn ions is achieved in relatively dilute conditions, leading to prolonged and efficient cycling of zinc metal anodes.}}, author = {{Gomez Vazquez, Dario and Pollard, Travis P. and Mars, Julian and Yoo, Ji Mun and Steinrück, Hans-Georg and Bone, Sharon E. and Safonova, Olga V. and Toney, Michael F. and Borodin, Oleg and Lukatskaya, Maria R.}}, issn = {{1754-5692}}, journal = {{Energy & Environmental Science}}, keywords = {{Pollution, Nuclear Energy and Engineering, Renewable Energy, Sustainability and the Environment, Environmental Chemistry}}, pages = {{1982--1991 (2023).}}, publisher = {{Royal Society of Chemistry (RSC)}}, title = {{{Creating water-in-salt-like environment using coordinating anions in non-concentrated aqueous electrolytes for efficient Zn batteries}}}, doi = {{10.1039/d3ee00205e}}, volume = {{16}}, year = {{2023}}, } @article{44271, author = {{Weadock, Nicholas J. and Sterling, Tyler C. and Vigil, Julian A. and Gold-Parker, Aryeh and Smith, Ian C. and Ahammed, Ballal and Krogstad, Matthew J. and Ye, Feng and Voneshen, David and Gehring, Peter M. and Rappe, Andrew M. and Steinrück, Hans-Georg and Ertekin, Elif and Karunadasa, Hemamala I. and Reznik, Dmitry and Toney, Michael F.}}, issn = {{2542-4351}}, journal = {{Joule}}, keywords = {{General Energy}}, pages = {{1051--1066}}, publisher = {{Elsevier BV}}, title = {{{The nature of dynamic local order in CH3NH3PbI3 and CH3NH3PbBr3}}}, doi = {{10.1016/j.joule.2023.03.017}}, volume = {{7}}, year = {{2023}}, } @inbook{45185, author = {{Hannebohm, Ronja}}, booktitle = {{Biopolitik(en) in Literatur, Film und Serie: Aushandlungs- und Reflexionsräume vom 18.

Milling by a focused ion beam enabled the comparison of the chemical composition of the surface layer with the bulk interface, showing no difference. The growth direction is both towards aluminum and steel — the main diffusion flux is from aluminum towards steel, and the new intermetallic phase emerges at the steel side. The shortage of Al atoms causes a shift of the intermetallic as a whole towards aluminum.}}, author = {{Šlapáková, Michaela and Kihoulou, Barbora and Veselý, Jozef and Minárik, Peter and Fekete, Klaudia and Knapek, Michal and Králík, Rostislav and Grydin, Olexandr and Stolbchenko, Mykhailo and Schaper, Mirko}}, issn = {{0042-207X}}, journal = {{Vacuum}}, keywords = {{Al-steel clad, twin-roll casting, 3D characterization, atomic force microscopy, diffusion direction, surface growth}}, publisher = {{Elsevier BV}}, title = {{{3D-structure of intermetallic interface layer in Al–steel clad material}}}, doi = {{10.1016/j.vacuum.2023.112043}}, volume = {{212}}, year = {{2023}}, } @inbook{45360, author = {{Haase, Michael and Bieber, Maximilian and Tasche, Frederik and Schaper, Mirko and Hoyer, Kay-Peter and Ponik, Bernd and Magyar, Balázs}}, booktitle = {{Proceedings of the 19th Rapid.Tech 3D Conference Erfurt, Germany, 9–11 May 2023}}, editor = {{Kynast, Michael and Eichmann, Michael and Witt, Gerd}}, isbn = {{978-3-446-47941-8}}, publisher = {{Carl Hanser Verlag GmbH & Co.
