AI Article Synopsis
- The study examines how acute exercise affects cognitive inhibition, focusing on specific neural markers (N450 and P3 components).
- Results show that both young and older males experienced faster response times and changes in neuroelectric activity after exercise compared to watching videos.
- Findings suggest that acute exercise enhances attention control and conflict monitoring, leading to improved performance in cognitive tasks, with similar benefits for both age groups.
Article Abstract
While considerable evidence supporting the positive influence of acute exercise on cognitive inhibition, little is known regarding the underlying cognitive processes. There is also little neuroelectric evidence regarding the effects on older adults of acute exercise-elicited cognitive benefits. Thus, our objective was to explore the possible neural markers underlying improved cognitive inhibition, with particular attention to the N450 and P3 components, following acute exercise. Another aim was to investigate whether cognitive gains seen in young adults are replicated in older adults. Twenty-four young males and 20 older males underwent either a single bout of aerobic exercise or video-watching in counterbalanced order. Afterwards, cognitive inhibition was assessed by the Stroop test. Results revealed that acute exercise resulted in shorter response time regardless of age or congruency. Regarding the neuroeletric data, acute exercise resulted in larger P3 amplitude and smaller N450 amplitude regardless of congruency or age. Further, following exercise, changes in response time interference were correlated with changes in incongruent N450 amplitude. Collectively, acute exercise-facilitated conflict monitoring and attention control, as signified by the N450 and P3 components, may be the underlying processes leading to better Stroop performance, with conflict monitoring having a stronger association with task performance. Further, cognitive gains resulting from acute exercise were found to the same extent in both young and older adults.

Comparing integrative ventilatory and renal acid-base acclimatization in lowlanders and Tibetan highlanders during ascent to 4,300 m.

With over 14 million people living above 3,500 m, the study of acclimatization and adaptation to high altitude in human populations is of increasing importance, where exposure to high altitude (HA) imposes a blood oxygenation and acid-base challenge. A sustained and augmented hypoxic ventilatory response protects oxygenation through ventilatory acclimatization, but elicits hypocapnia and respiratory alkalosis. A subsequent renally mediated compensatory metabolic acidosis corrects pH toward baseline values, with a high degree of interindividual variability.

Background: Subacromial impingement syndrome (SIS) is a common cause of shoulder pain and dysfunction. Modified posterior shoulder stretching exercises have been proposed as a treatment method aimed at improving shoulder function and reducing pain in patients with SIS. However, the efficacy of these exercises remains controversial, necessitating a systematic meta-analysis to comprehensively evaluate their effectiveness.

Hepatocellular carcinoma (HCC) presents an escalating public health challenge globally. However, drug resistance has emerged as a major impediment to successful HCC treatment, limiting the efficacy of curative interventions. Despite numerous investigations into the diverse impacts of hsa-miR-125a-5p on tumor growth across different cancer types, its specific involvement in chemotherapy resistance in HCC remains elusive.
