Cognitive decline is an important feature of an aging population. Despite the large body of research investigating the effects of high-intensity interval training (HIIT) on cognitive performance, reports of its effectiveness are inconsistent and it is difficult to determine what factors moderate these effects. The purpose of this study was to conduct a meta-analysis of existing randomised controlled trials investigating the effects of HIIT on various domains of cognitive performance, and to further examine the intervention cycle and age-related moderating effects. A comprehensive literature search was conducted across a range of databases, including PubMed, Embase, the Cochrane Library, Web of Science, Scopus, and EBSCO. The meta-analysis included data from 20 RCT studies. The results of the analyses demonstrated that HIIT significantly enhanced information processing (SMD = 0.33, 95% CI: 0.15–0.52, P = 0.0005), executive function (SMD = 0.38, 95% CI: 0.26 – 0.50, P < 0.00001), and memory (SMD = 0.21, 95% CI: 0.07–0.35, P = 0.004). Subgroup analyses demonstrated that HIIT enhanced information processing in individuals aged 60 and above, improved executive functioning in individuals of all ages, and enhanced memory in individuals aged 30 to 60. Acute HIIT improved executive function, less than 8 weeks of HIIT improved executive function and memory, and more than 8 weeks of HIIT improved information processing, executive function and memory. The findings of this study indicate that HIIT has a beneficial effect on cognitive performance. Chronic HIIT represents a potential non-pharmacological intervention for cognitive health. Further high-quality research is required to validate and extend these findings.

A C8P monolayer with cross-sp-hybridized phosphorus atoms and ultrahigh energy density as a K-ion battery anode† K-ion batteries (KIBs) are promising alternatives to Li-ion batteries due to the abundant availability of K and the similar chemical attributes of K and Li. However, the development of KIBs is significantly hindered by the lack of viable anode materials.

OBJECTIVES: To investigate the diagnostic performance of the apparent diffusion coefficient (ADC) for low to intermediate-risk prostate cancer (PCa), as well as its correlation with the prognostic Gleason score (GS). MATERIALS AND METHODS: Retrospective analysis of MRI images and relevant clinical data from patients with prostate disease. The differences in ADC between different GS groups were compared, and the efficacy of ADC in PCa diagnosis were analyzed.
