Background: Regular physical activity benefits both and mental health. Yet, inactivity remains widespread, including in Lebanon, with significant health consequences. While objective subjective tools for measuring exist, self-report questionnaires like the Physical Activity Index (PAI) are practical cost-effective large-scale population studies. However, PAI has not been validated Arabic-speaking populations. This study intended to evaluate psychometric properties of an Arabic translation PAI, aim providing adapted tool assess activity, support public initiatives research efforts Arab-speaking regions. Methods: The forward-backward method was adopted. Data collected through a one-time online survey from sample Lebanese adults (N = 462; mean age 25.85 ± 9.69 years; 70.3% females). Results: Exploratory factor analysis revealed single-factor structure version PAI. A Cronbach’s alpha 0.71 indicated acceptable internal consistency. The invariant across gender, consistency males (α 0.78) females 0.68). In total sample, 23.15 18.81, indicating poor no gender differences (males: 21.32, females: 22.01 17.55; t(460) 1.86, p 0.064).

<abstract> <p>It is widely accepted that physical exercise can be used as a tool for the prevention and treatment of various diseases or disorders. In addition, in recent years, has also been successfully to enhance people's cognition. There large amount research supported benefits on human cognition, both children adults. Among these studies, some have focused acute transitory effects while others regular exercise. However, relation between cognition complex we still limited knowledge about moderators mechanisms underlying this relation. Most studies behavioral aspects exercise-effects animal deepened its possible neuro-physiological mechanisms. Even so, thanks advances neuroimaging techniques, there growing body evidence provides valuable information regarding population.

Examining the Effect of Increased Aerobic Exercise in Moderately Fit Adults on Psychological State and Cognitive Function

Frontiers in Human Neuroscience, Journal Year: 2022, Volume and Issue: 16

Published: July 12, 2022

Regular physical exercise can decrease the risk for obesity, diabetes, and cardiovascular disease, increase life expectancy, promote psychological health neurocognitive functioning. Cross-sectional studies show that cardiorespiratory fitness level (VO 2 max) is associated with enhanced brain health, including improved mood state heightened cognitive performance. Interventional are consistent these cross-sectional studies, but most have focused on low-fit populations. Few such asked if increasing levels of activity in moderately fit people significantly enhance mood, motivation, cognition. Therefore, current study investigated effects aerobic individuals We randomly assigned healthy adults, 25–59 years age, who were engaged one or two sessions per week to either maintain their regimen ( n = 41) (i.e., 4–7 workouts week; 39) a duration 3 months. Both before after intervention, we assessed capacity using modified test, hippocampal functioning via various neuropsychological assessments spatial navigation task Mnemonic Similarity Task as well self-reported measures Positive Negative Affect Scale, Beck Anxiety Inventory, State-Trait Perceived Stress Rumination Eating Disorders Examination, Attitudes Test, Body Behavioral Regulation Exercise Questionnaire.

Does Prefrontal Cortex Oxygenation Mediate Executive Function During High-Intensity Exercise? A Systematic Review of Fnirs Studies

Published: Jan. 1, 2025

The transient hypofrontality hypothesis posits that cognitive resources are deprioritized in favor of motor demands during extreme physical stress, potentially reducing prefrontal cortex (PFC) activation and impairing executive function (EF). Although prior studies have attempted to investigate the effects PFC oxygenation, measured via functional near-infrared spectroscopy (fNIRS), on EF high-intensity exercise, results remain inconclusive. This systematic review examined whether oxygenation plays a mechanistic role changes performance focusing insights from fNIRS studies. Following PRISMA guidelines, comprehensive literature search across several electronic databases identified 468 studies, which five met inclusion criteria. Some reported impairments associated with reduced while others observed stable or increased without significant impairments. These inconsistencies may arise methodological variations, extracerebral confounders, individual differences. findings highlight as critical yet context-dependent factor regulation but suggest it not directly mediate under such dual-task paradigms. supports need for standardized protocols, advanced neuroimaging techniques, multi-modal approaches better understand effect.

Acute aerobic exercise enhances associative learning in regular exercisers but not in non-regular exercisers

Frontiers in Behavioral Neuroscience, Journal Year: 2025, Volume and Issue: 18

Physical exercise has repeatedly been reported to have advantageous effects on brain functions, including learning and memory formation. However, objective tools measure such are often lacking. Eyeblink conditioning is a well-characterized method for studying the neural basis of associative learning. As such, this paradigm potential as tool assess what extent affects one most basic forms Until recently, however, using testing human subjects in their daily life was technically challenging. consequence, no studies investigated how eyeblink humans. Here we hypothesize that acute aerobic associated with improved performance conditioning. Furthermore, explored whether differed people engaging regular versus those who were not. We conducted case-control study smartphone-based platform conducting neurometric healthy adults aged between 18 40 years (n = 36). Groups matched age, sex, education level. Our primary outcome measures included amplitude timing conditioned eyelid responses over course training. secondary measure, studied unconditioned responses. Acute significantly enhanced acquisition responses; effect only true regularly exercising individuals. No statistically significant established This highlights facilitative role emphasizes importance accounting long-term habits when investigating functioning.

The circadian clock is an endogenous timekeeping system that regulates various physiological and behavioral processes. Recently, it has been shown the timing of physical activity food intake can significantly influence metabolic muscle health. Some recent clinical evidence practiced in late afternoon be more effective terms performance strength. Preclinical studies have highlighted explanation for this effect lies different daily expression genes clock-controlled involved development hypertrophy. In conjunction with scientific advances understanding molecular mechanisms regulate rhythms trophy, chrono-nutrition gained resonance become a promising field, aimed at regulation body metabolism. Clinical preclinical protein consumption specific time points during day, or precisely after exercise, activate signaling pathways synthesis and, thus, favor skeletal mass as well mitochondrial biogenesis, thereby improving cell energy production function. On other hand, some carbohydrates immediately exercise increases insulin secretion, which facilitates glucose uptake by cells to replenish glycogen. This review summarizes current literature concerning chrono-exercise health, focusing on involving mass, strength, Understanding intricate relationship between rhythms, nutrition, metabolism essential optimizing nutritional strategies prevent treat wasting. addition, tailoring carbohydrate individual needs improve maintenance, growth, performance.

This study examined the impact of using bike desks on cognitive function and memory among university students. Physical activity during adolescence offers enduring health benefits, yet sedentary behaviors prevail young adults, posing significant risks. Bike desks, integrating stationary cycling with ergonomic desk designs, aim to mitigate behavior while enhancing performance. Research indicates that acute aerobic exercise improves executive functions, memory, attention, which is particularly beneficial in educational settings. The employed verbal paired associates learning task (VPAT) assess performance when either usage at moderate intensity (intervention) or rest (control condition) occurred before encoding early consolidation 26 adult medicine nursing students a library setting.
