AI Article Synopsis
- The study aimed to explore how low energy availability affects performance outcomes in male athletes, focusing on a potential dose-response relationship and identifying knowledge gaps.
- A scoping review of the literature was conducted, analyzing six studies with 103 male athletes, revealing mixed results on performance outcomes like strength, endurance, and speed due to varying energy levels.
- The findings suggest that low energy availability can yield both positive and negative effects on performance, but further research is needed to clarify these results due to methodological limitations.
Article Abstract
Objectives: The primary aim of this study was to investigate the effects of low energy availability on different performance outcomes in male athletes. Secondary aims were to examine an assumed dose-response relationship and identify knowledge gaps.
Design: Scoping review.
Methods: The electronic database PubMed was searched until the end of June 2023. Additionally, we used reference tracking and hand-searching for related articles. Six studies with a total of 103 male athletes met the inclusion criteria.
Results: Four of the included studies had an interventional study design, including one case study, and the remaining two were cross-sectional studies. Different performance outcomes (i.e., strength, endurance, speed) were either positively, negatively, or unaffected by low energy availability. The length and magnitude of the low energy availability, as well as the baseline status of the athletes could have influenced the results. Additionally, there are methodological considerations that might limit the validity of the results.
Conclusions: Current evidence shows heterogeneous results, as some studies suggested improvements in certain performance parameters, whilst other studies showed neutral or detrimental effects of low energy availability. Due to the limitations mentioned; additional research is warranted for a more comprehensive understanding.

Many types of spatiotemporal patterns have been observed under nonequilibrium conditions. Cycling through four or more states can provide specific dynamics, such as the spatial coexistence of multiple phases. However, transient dynamics have only been studied by previous theoretical models, since absorbing transition into a uniform phase covered by a single state occurs in the long-time limit.

Sustainable pavement is essential for country development, offering durable, environmentally friendly, and cost-effective infrastructure. For Malaysia, sustainable pavement supports Sustainable Development Goals (SDGs) 9 and 11 while addressing road deterioration caused by increasing traffic volumes and loads. This deterioration shortens pavement service life and necessitates frequent maintenance, driving the need for innovative solutions.

Purpose Of Review: This review examines the long-term efficacy and safety of various nutritional and pharmacological strategies for managing obesity. The focus is on the Mediterranean diet (MedDiet), very low-energy ketogenic therapy (VLEKT), and pharmacological interventions such as naltrexone/bupropion and liraglutide. Given the chronic nature of obesity, understanding the sustainability and impact of these treatments over time is critical.

Nanomedical applications have increased significantly. This work aimed to fabricate and characterize cobalt oxide nanoparticles (CoOnps) synthesized biologically via aqueous Alhagi maurorum extract and evaluate their cytotoxic and antimicrobial impacts. Green-synthesized CoOnps were prepared and analyzed using UV-Vis spectrophotometer UV-vis, Scanning electron microscopy (SEM), Transmission electron microscopy TEM, Energy dispersive X-ray analysis EDAX, Fourier transform infrared, FTIR, and X-ray diffraction (XRD).

Prussian blue analogs (PBAs), as a classical kind of microporous materials, have attracted substantial interests considering their well-defined framework structures, unique physicochemical properties and low cost. However, PBAs typically adopt cubic structure that features small pore size and low specific surface area, which greatly limits their practical applications in various fields ranging from gas adsorption/separation to energy conversion/storage and biomedical treatments. Here we report the facile and general synthesis of unconventional hexagonal open PBA structures.
