Summary: The study found that exhaustive exercise in hyperoxia can increase the maximum oxygen consumption rate and aerobic scope in rainbow trout by improving cardiac function and blood parameters. This suggests that hyperoxia can enhance maximal cardiac performance, tissue oxygen delivery, and maintain a higher maximum oxygen consumption rate.

Summary: Compared to conventional racing shoes, Nike Vaporfly 4% running shoes can reduce the metabolic cost in level, uphill, and downhill running. However, the savings provided during uphill running are relatively smaller.

Summary: Individuals with cerebral palsy (CP) have higher energy expenditure and oxygen cost during walking compared to age-matched typically developing (TD) individuals, with a strong relationship across Gross Motor Function Classification System (GMFCS) levels. Oxygen cost is considered the preferred parameter to assess walking efficacy in CP, but there is a knowledge gap in age-related changes of walking efficiency across GMFCS levels. Further longitudinal research is needed to explore the energetics of walking in this population.

Summary: Increasing water temperature due to climate change affects the physiological functions of aquatic organisms, including shrimp. This study found that the optimal temperature range for Pacific white shrimp post-larvae is 25-30 degrees Celsius based on their critical temperatures and metabolic rates.

Summary: The study estimated the metabolic rate and aerobic capacity of lab-reared juvenile Brook Trout across a range of temperatures, showing that the fish exhibit adaptability at different temperatures and maintain similar physiological performance across a wide range of temperatures, indicating they are eurythermal.

Summary: Physiologists commonly use single-value energy equivalents to convert oxygen uptake to energy, but doing so ignores how the substrate oxidation ratio changes across aerobic intensities. Using these values can lead to systematic errors of up to 7%. The best approach for estimating energy expenditure is to measure both oxygen uptake and carbon dioxide production and use accurate stoichiometry.

Summary: The study found distinct responses of temperature, oxygen, and carbon dioxide in aerobic microbial respiration of silage. The novel multi-sensor technique has the capacity to provide detailed information on AMR and guide silage management effectively. These results offer insights into the aerobic stability of silage beyond traditional measurements.

Summary: Density functional theory calculations are used to understand the atomic structural transitions of pyrochlore oxides. It is found that the migration of oxygen atoms during disordering process can transform the local pyrochlore structure to the weberite structure. The degree of disordering is characterized by the oxygen migration ratio, and it is influenced by the cation properties. The study provides new insights into the disordering mechanism of pyrochlores and may guide the design of materials with tailored properties.

Summary: Eccentric exercise can generate greater mechanical loads with lower cardiopulmonary demands, leading to gains in muscle mass and strength. However, its impact on oxygen transport and factors for prescription and monitoring require more research.

Summary: The research proposes a hypothesis about water-breathing ectothermic animals, suggesting that they regulate peak specific dynamic action response during times of warming by reducing meal sizes to protect postprandial residual aerobic scope, leading to reductions in growth.

Summary: This study reveals the spatio-temporal pattern of water use in China from 2007 to 2015 and its local and non-local drivers. The results show that although China's total water use exhibited an upward trend initially, it started to decrease after 2012 due to improvements in water use efficiency and changes in economic structure. Migration effects also played a role in the changing water use across different regions.

Summary: The study found that rotifers exhibited clone- and condition-specific responses to hypoxia and temperature, with different response strategies equally successful in maintaining fitness levels. The important conclusion was that body size decrease at higher temperatures enabled the maintenance of aerobic scope under clone-specific, thermally optimal conditions, and there are alternative options to prevent fitness reduction under hypoxia.

Summary: Climate warming has negative consequences for fishes, reducing their aerobic scope and performance. The hypothesis that fishes select temperatures to maximize their aerobic scope remains controversial. A study on zebrafish found that their temperature preference is influenced by factors other than maximizing their aerobic scope.
