Consistent prescriptions for event-specific training of swimmers are lacking, which points to likely differences in training practices and a potential gap between practice and scientific knowledge. This study aimed to analyze the distance-specific training load of elite swimmers, derive a consistent training sessions' description and reflect on the current recommendations for training and recovery. The individual training regimes of 18 elite British swimmers were documented by surveying four swim and two strength and conditioning (S&C) coaches. The annual and weekly training load and content were compared between swimmers competing in sprint, middle and long-distance events. Thematic analysis of the surveys was conducted to identify key codes and general dimensions and to define a unified classification of the swimming and S&C training sessions. Weekly training loads and content of the swim (ƞ - effect size; p = 0.016, ƞ = 0.423) and S&C (p 0.028, ƞ = 0.38) sessions significantly differed between the groups. Long-distance swimmers swam significantly longer distances (mean ± SD; 58.1 ± 10.2 km . 43.2 ± 5.3 km; p = 0.018) weekly but completed similar number of S&C sessions compared to sprinters. The annual swimming load distribution of middle-distance specialists did not differ from that of long-distance swimmers but consisted of more S&C sessions per week (4.7 ± 0.5 . 2.3 ± 2.3; p = 0.04). Sprinters and middle-distance swimmers swam similar distances per week and completed similar number of S&C sessions but with different proportional content. Whereas all coaches reported monitoring fatigue, only 51% indicated implementing individualized recovery protocols. We propose a consistent terminology for the description of training sessions in elite swimming to facilitate good practice exchanges. While the training prescription of elite British swimmers conforms to the scientific training principles, recommendations for recovery protocols to reduce the risk of injury and overtraining are warranted.

Background: Smartwatches are increasingly popular for physical activity and health promotion. However, ongoing validation studies on commercial smartwatches are still needed to ensure their accuracy in assessing daily activity levels, which is important for both promoting activity-related health behaviors and serving research purposes.
Objective: This study aimed to evaluate the accuracy of a popular smartwatch, the Huawei Watch GT2, in measuring step count (SC), total daily activity energy expenditure (TDAEE), and total sleep time (TST) during daily activities among Chinese adults, and test whether there are population differences.

FOXO3a is a transcription factor involved in cell growth inhibition and apoptosis. FOXO3a is localized in the cytoplasm in cancer cells, and its nuclear translocation by small molecules is expected to prevent cancer cell growth. In this study, we screened a fungal broth library in HeLa cells using fluorescently labeled FOXO3a and an AI-based imaging system.

The construction of an ecological security pattern is crucial to maintain ecosystem health and stability, with great significance for regional sustainable development. Following the research paradigm of "ecological source areas-ecological resistance surfaces-ecological corridors", based on the index framework of "sensitivity-importance-connectivity", we identified the ecological source areas, generated the ecological resistance surface through graded weighting of underlying surface factors and point of interest (POI) method, determined the ecological corridor, pinch point, and obstacle area using circuit theory, and constructed the ecological security pattern of Guizhou Pro-vince. Results showed that the areas of extremely sensitive of rocky desertification and soil erosion and the areas of extremely important areas of water resources forming, soil and water conservation and biodiversity in Guizhou Pro-vince were generally small and distributed differently, accounting for 1.

We analyzed the differences in knot property of linear and curved knots of dominant, medium, and inferior wood with thirty-three trees from Mengjiagang Forest Farm and Linkou Forestry Bureau in Heilongjiang Province. We divided the 33 trees into two groups according to the height of the site index. We constructed a trunk diameter growth models to explore the connection, between the knot growth inflection points and the successive growth of diameter, and to screen for the types that had a weaker impact on wood quality.

Carbon balance of the tree layer in natural forests is affected by three carbon pools: tree growth, morta-lity, and recruitment. However, the dynamics of the sink of each carbon pool and the driving factors are still unclear. To this end, we used stepwise regression method and structural equation model to assess the effects of biotic (stand and diversity) and abiotic (soil, topography and climate) factors on three dynamic processes of carbon sinks, namely, stand growth, recruitment and mortality, in the natural forests of , based on the data from the seventh and eighth national continuous forest inventory of the Greater Khingan Mountains.
