Background: Artistic Gymnastics is a sport where athletes are frequently fatigued. One element that might influence this aspect is carbohydrate, an important energy substrate for the muscles and the CNS. Our goal was to investigate the influence of fatigue over artistic gymnastics athlete's performance and the effects of a carbohydrate supplementation on their performance.
Methods: We evaluated 15 athletes divided in 2 groups (control and fatigue) from 12 to 14 years old in two different experimental days. On the first day (water day), they did 5 sets of exercises on the balance beam (experimental protocol) ingesting only water, CG (control group) warmed up before the experimental protocol and FG (fatigue group) did a fatigue circuit, warm up exercises and then the experimental protocol. On the second day (carbohydrate day), we used the same protocol but CG ingested a sugar free flavored juice and FG ingested a 20% concentration maltodextrin solution before the protocol on the balance beam.
Results: We observed a greater number of falls from the balance beam from the FG on the first day (5.40 ± 1.14 FG vs 3.33 ± 1.37 CG; p = 0.024) and a decrease in the number of falls on the second day (2.29 ± 1.25 FG water day vs 5.40 ± 1.14 FG carbohydrate day; p = 0.0013). Carbohydrate solution was able to supply muscle demands and improve the athlete's focus showed by the reduced number of falls.

This study investigated the prospective associations between changes in 24-h movement behaviors and physical fitness (PF) components in preschool children; and examined how the reallocation of time between movement behaviours was associated with longitudinal changes in PF. This is a two-year longitudinal study of 200 Chinese children aged 3-4 years old. At baseline and follow-up, 24-h movement behaviors including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), screen-based sedentary behavior (SSB), non-screen-based sedentary behavior (NSB), and sleep were assessed.

The H-beam riveting and welding work cell is an automated unit used for processing H-beams. By coordinating the gripping and welding robots, the work cell achieves processes such as riveting and welding stiffener plates, transforming the H-beam into a stiffened H-beam. In the context of intelligent manufacturing, there is still significant potential for improving the productivity of riveting and welding tasks in existing H-beam riveting and welding work cells.

Background: Increasing balance and stability, along with efficient locomotion, is a high-priority goal of physical rehabilitation after limb loss in order to facilitate effective participation in society. Research in the general population suggests that the ability to walk fast is correlated to good performance in balance tests. However, it is unclear if and how prosthesis use influences this correlation.

Introduction And Aims: Calcified root canals in mandibular anterior teeth present significant therapeutic challenges due to their narrow anatomy and minimal tolerance for procedural errors. This case report demonstrates the successful integration of robot-assisted navigation with an ultra-fine bur to address these challenges.
Methods: A 44-year-old male presented with symptomatic chronic apical periodontitis and pulp calcification in a mandibular lateral incisor, 20 years after orthodontic treatment.

Extensive cut slopes resulting from anthropogenic engineering activities in alpine mining areas of the Qinghai-Tibet Plateau have led to soil structure fragmentation and nutrient loss, threatening ecosystem stability. This study systematically compared soil aggregate stability and carbon-nitrogen-phosphorus nutrient characteristics among three restoration methods for cut slopes (three-dimensional netting [TCS], frame beams [FCS], and galvanized wire mesh [GCS]) relative to unrestored cut slopes (UCS) in the Jiama Mining Area, Tibet. The results demonstrated that TCS and FCS significantly increased the proportion of soil macroaggregates (>0.
