Abstract Background In a recent study, we examined Covid-19 pandemic effects on the physical fitness of German third-graders tested between 2016 and 2022. The present report includes new data from 2023 to examine whether there were post-pandemic rebounds in negatively affected components, potential rebound differed by school social status. Methods EMOTIKON project annually tests all Federal State Brandenburg, Germany. Tests assess cardiorespiratory endurance (6-min-run), coordination (star-run), speed (20-m linear sprint), lower (powerLOW, standing long jump), upper (powerUP, ball-push test) limbs muscle power, static balance (one-legged-stance test). A total 108,308 aged 8 9.2 years 444 schools falls 2023. Linear mixed models, specified for regression discontinuity design with random factors child school, estimated first day year 2020/21 (i.e., critical date), as well cohort trends before after onset. Results Higher status was associated better endurance, coordination, speed, powerLOW. At date, small negative powerUP. Pandemic larger higher Coordination powerUP characterized rebound, slightly There no evidence speed. Conclusions Absence task-specific may indicate long-term consequences pandemic-related movement restrictions. Lower powerLOW low need improved access sports opportunities these schools.

This study presents the optimization of two SPR biosensors, Sys3 and Sys5, for SARS-CoV-2 detection at concentrations 0.01-100 nM. Sys3, with a 55 nm silver layer, 13 silicon nitride 10 ssDNA achieved figure merit (FoM) 571.24 RIU-1, signal-to-noise ratio (SNR) 0.12, accuracy (DA) 48.93 × 10-2. incorporating 50 1.6 tungsten disulfide layer (L = 2), demonstrated higher sensitivity 305.33 °/RIU lower limit (LoD) 1.65 10-5. outshined in precision low attenuation (<1%), while Sys5 provided enhanced limits, crucial early-stage viral detection. These configurations align refractive index ranges clinical samples, showcasing their diagnostic potential. Future work will focus on experimental validation integration into point-of-care platforms.
