Exoskeletons offer a promising approach to reduce this stress by supporting the wearer during physical labour. This study investigated the effect of an active exoskeleton (Apogee) on muscle activation and joint kinematics during load lifting at different lifting speeds and exoskeleton support levels.\r\n\r\nMethods: Sixteen healthy young adults (8 male, 8 female) lifted a 15 kg box at two lifting speeds (9 and 12 lifting cycles/min) and four support levels: 1) without exoskeleton, 2) exoskeleton in passive mode, 3) 50% support and 20% counterforce, 4) 100% support and 60% counterforce. Muscle activity was measured in the M. erector spinae (MES), M. biceps femoris (MBF) and M. vastus medialis (MVM) using EMG. Furthermore, joint range of motion (ROM) in the ankle, knee and hip were analysed using 3D motion capture.\r\n\r\nResults: Faster lifting significantly (p < 0.05) increased MBF (by 4.0% ± 1.5% maximum voluntary contraction, MVC) and MVM (1.6% ± 0.7% MVC) activity, while MES remained unaffected. The highest support level led to a significant decrease in MES and MBF activity by about 22.3% MVC and 10.6% MVC, respectively, as well as a small increase in hip joint ROM by 6° compared to lifting without exoskeleton support. There was no interaction between the level of support and lifting speed.\r\n\r\nDiscussion: The decrease in MES activity of 22.3% MVC with full support suggests a potent reduction in spinal load. MBF activity increased less with higher speeds when support was applied. The MVM showed low and stable activity across all conditions. These findings suggest that the active exoskeleton Apogee provides support regardless of lifting speed and may help prevent MSDs in occupational settings. Users can adjust support levels based on task requirements and personal comfort.", "language" : "English", "doi" : "10.3389/fbioe.2025.1685634", "bibtexKey": "mayer2025biomechanical" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2eedb4246bf0415d85de9fe3aff3ab080/ipappwiedmann", "tags" : [ "Acid","Activity","Electrolyte","Fe-N-C","Impact","Modification","Oxygen","Phosphoric","Reaction","Reduction","Stability","and","for","in","ofAerogel","towards" ], "intraHash" : "eedb4246bf0415d85de9fe3aff3ab080", "interHash" : "3d229d88f28682848603bfa57e5c43eb", "label" : "Impact ofAerogel Modification for Fe-N-C Activity and Stability towards Oxygen Reduction Reaction in Phosphoric Acid Electrolyte", "user" : "ipappwiedmann", "description" : "", "date" : "2025-05-12 11:33:30", "changeDate" : "2025-05-27 09:24:30", "count" : 1, "pub-type": "article", "journal": "ChemSusChem", "year": "2024", "url": "", "author": [ "T.

In vivo experiments and computer simulation results suggest that muscles\u2019 preflex\u2014an immediate mechanical response to a perturbation\u2014could be the critical contributor. Muscle preflexes act within a few milliseconds, an order of magnitude faster than neural reflexes. Their short-lasting action makes mechanical preflexes hard to quantify in vivo. Muscle models, on the other hand, require further improvement of their prediction accuracy during the non-standard conditions of perturbed locomotion. Our study aims to quantify the mechanical work done by muscles during the preflex phase (preflex work) and test their mechanical force modulation. We performed in vitro experiments with biological muscle fibers under physiological boundary conditions, which we determined in computer simulations of perturbed hopping. Our findings show that muscles initially resist impacts with a stereotypical stiffness response\u2014identified as short-range stiffness\u2014regardless of the exact perturbation condition. We then observe a velocity adaptation to the force related to the amount of perturbation similar to a damping response. The main contributor to the preflex work modulation is not the change in force due to a change in fiber stretch velocity (fiber damping characteristics) but the change in magnitude of the stretch due to the leg dynamics in the perturbed conditions. Our results confirm previous findings that muscle stiffness is activity-dependent and show that also damping characteristics are activity-dependent. These results indicate that neural control could tune the preflex properties of muscles in expectation of ground conditions leading to previously inexplicable neuromuscular adaptation speeds.", "language" : "English", "doi" : "10.3389/fbioe.2023.1150170", "bibtexKey": "siebert2023active" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/27a92a0ea46e6274ea9e3a0b023c57bff/huebleriac", "tags" : [ "activity","antimicrobial","complex","crystal","metal","pesticide","prepn","pyridinylmethylthioquinoline","pyridinylmethylthioquinoline;bactericidal","pyridinylmethylthioquinoline;electrochem","pyridinylmethylthioquinoline;transition","redox","structure","transition" ], "intraHash" : "7a92a0ea46e6274ea9e3a0b023c57bff", "interHash" : "f87287218876bef94708a4828b035f78", "label" : "Structure, biological and electrochemical studies of transition metal complexes from N,S,N' donor ligand 8-(2-pyridinylmethylthio)quinoline", "user" : "huebleriac", "description" : "", "date" : "2022-06-15 11:26:56", "changeDate" : "2022-06-15 09:26:56", "count" : 3, "pub-type": "article", "journal": "Polyhedron", "year": "2010", "url": "", "author": [ "Jing-An Zhang","Mei Pan","Rui Yang","Zhi-Gang She","Wolfgang Kaim","Zhi-Jin Fan","Cheng-Yong.
