Summary: Analyzing the modeling of intermittent work capacity in elite cyclists, the Bartram adjustment was found to be an improvement over the Skiba 2 model, with a focus on W' in this population. However, in the specific context of team pursuit races, all models were too variable for effective use, indicating the need for exploration of individual recovery rates beyond population-specific rates.

Summary: Limited data exists on the effects of sex on sprint interval cycling (SIC) performance. This study investigated sex-based differences in collegiate soccer players and found significant differences in certain performance parameters, but overall performance variations were likely due to differences in body composition.

Summary: The purpose of this study was to investigate the effects of flat and uphill cycling on critical power and the work available above critical power. The results indicate that gradient affects cycling time-trial performance, power output at critical power, and the amount of work available above critical power.

Summary: This study compared previous calculating formulas of maximal lactate accumulation rate (La.max) and a modified formula of pure La.max (P-La.max) during a 15-s all-out sprint cycling test (ASCT) and analyzed their relationships. The study found that P-La.max and La.max (t(PCr-peak)) were highly correlated, with a higher correlation than P-La.max and La.max (t(PCr-3.5%)). The modified calculation of P-La.max provides more detailed insights into the inter-individual differences in energy and glycolytic metabolism than the previous formulas.

Summary: This study compared the effect of bilateral knee joint cooling with or without a pre-cooling warm-up on sprint cycling performance. The results showed that a bilateral joint cooling for 20 min, regardless of pre-cooling warm-up, may improve overall sprint cycling capacity during five sets of cycling intervals.

Summary: This study evaluates the performance of ferrocenyl derivatives as shuttles in redox-targeting flow batteries and finds that a dual system outperforms other systems in terms of battery performance. The study also reveals that the rate of redox targeting dictates the system's performance and depth of charge.

Summary: The study aimed to determine whether a 2-minute constant work rate (CWR) cycling test can act as a proxy for a 4-minute test. The results showed a strong correlation between the outcomes of the 2-minute and 4-minute tests, indicating that the shorter test can be used as a substitute for the longer test. The shorter test reduces physiological stress and performance fatigability, making it more practical for elite athletes in their training and competition preparation.

Summary: Nitrogen pollution is a major threat to global sustainable development and has recently gained increased attention. The combination of microbially mediated Mn redox cycling and N removal shows promise as an economical, efficient, and environmentally friendly alternative. This review explores the key factors, theories, and mechanisms of Mn species in driving the biogeochemical cycle, and summarizes the application and development trends of Mn redox cycling in water treatment, particularly in simultaneous N and micropollutant removal. Bibliometric analysis identifies research hotspots, gaps, challenges, and future directions for Mn redox-mediated biological N removal. Overall, this review aims to guide the further development and optimization of Mn redox-mediated microbial N removal processes to establish cost-effective N removal techniques for contaminated water.

Summary: This study aimed to determine how rider ability and measures of critical power (CP) and finite work capacity (W') impact team pursuit (TP) performance, and to explore the extent of W' reconstitution during a TP race. The results showed that the rate of W' reconstitution and CP have a greater impact on TP performance than the magnitude of W', and can differentiate TP performance level.

Summary: The study found that CP (256 ± 50 W) was significantly higher than FTP (249 ± 44 W) with a strong correlation between the two, but potential meaningful differences in terms of performance should be considered. Therefore, caution should be exercised when choosing between FTP and CP for performance analysis.

Summary: The aim of this study was to develop and validate a bioenergetic model describing the dynamic behavior of different energy supply systems and energy demands. The model was formulated as a system of differential equations and validated using data from experimental trials. The validation showed good agreement between measured and modeled metabolic rates during intermittent cycling, although there was some variability.

Summary: This systematic review and network meta-analysis examined the effects of different nutritional supplementation strategies and exercise interventions on acute and chronic rowing performance. The results showed that caffeine had a positive impact on acute rowing performance, while weight reduction and extensive preload had negative effects. Chronic blood flow restriction training and the combination of beta-hydroxy-beta-methylbutyrate and creatine had positive effects on chronic performance, while spirulina and black currant supplementation had negative effects.

Summary: This article proposes a data-driven framework for evaluating degradation of overcharged lithium-ion batteries. It includes a multilevel overcharge cycling experiment to analyze battery degradation behaviors and features, and develops a machine learning and model integration method for evaluation. The proposed method achieves a mean squared error of 1.26 x 10(-4) and effectively identifies overcharged cells.

Summary: The study aimed to compare the effects of different statistical fitting procedures on critical speed (CS) estimates, and analyze the correlations between estimated CS and aerobic fitness parameters. Results showed significant effects of different mathematical models on estimating CS, d', and s(max), with high correlations between CS and aerobic fitness parameters. The choice of mathematical model for estimating critical speed may not significantly impact the results, but there are high correlations with aerobic fitness parameters.
