Filter by:REACT is a randomized intervention to examine the benefits of African Dance as a method to increase physical activity behaviors in older adults. In this 6- month intervention, older African Americans will be randomly assigned to either an African Dance or an Africana Culture class. Both before and at the completion of the intervention, the investigators will collect a comprehensive neuropsychological battery and MRI scans of brain health and function to better study how physical activity influences neurocognitive health in African Americans.
Cognitive performance is negatively related to an impaired glucose metabolism, possibly due to impairments in brain vascular function. Supported by the statement from the American Heart and American Stroke Association that healthy plant-based diets, which consist of soy foods, protect against cognitive decline, we now hypothesize that soy-induced changes in glucose metabolism cause beneficial effects on brain vascular function thereby improving cognitive performance. The primary objective of this intervention study is thus to evaluate in elderly men and women the effect of a 16-week soy intervention on cerebral blood flow, as quantified by the non-invasive gold standard magnetic resonance imaging (MRI) perfusion method Arterial Spin Labeling (ASL). Cerebral blood flow is a robust and sensitive physiological marker of brain vascular function. Secondary objectives are to examine effects on glucose metabolism using the oral glucose tolerance test and cognitive performance as assessed with a neurophysiological test battery.
This study seeks to observe the effects of a proprietary spearmint extract and green tea blend on sleep quality and duration. The study observes the effect of the supplement regarding sleep quality, and mental health.
We designed a double-blind, community-based, cluster-randomized control trial which will test to establish novel evidence on the efficacy of iron-fortified lentil in improving body Fe status of non-pregnant adolescents in rural Mymensingh district of Bangladesh. Lentils will be fortified with iron in the lab setting at the Crop Development Center (CDC) of the University of Saskatchewan in Canada. There will be three lentils based dietary intervention arm in this efficacy trial. Arm 1 will be intervened with iron-fortified lentils, Arm 2 will be non-iron fortified lentils, and Arm 3 arm will be the usual intake of lentil (no additional lentil). Arm 2 will be served as a comparison group and arm 3 will be served as control group. A total of 420 adolescent girls (including 20% drop-outs) - aged 10 - 17y; non-smoking, not pregnant, not breastfeeding, and generally healthy will be included in each arm - a total of 1260 adolescent girls in all three arms. Participating adolescents will be served thick preparation of cooked lentils (37.5gm raw lentil) 5 days a week for 85 feeding days (around 4+months). Socio-demographic characteristics, household food security status, and adolescent food habits will be collected at baseline and endline data point. Furthermore, venous blood will be collected to measure adolescents' Fe status at baseline, midline, and endline for 85 feeding days (5 days a week)- approx. 4+ months. In addition, Ravens Progressive Matrices will be used for non-verbal measurement of the cognitive ability of advanced observation and thinking skills specific to capacity for analyzing and solving problems, abstract reasoning, and the ability to learn of the adolescents. Both descriptive and inferential statistics will be used for this study. Serum ferritin level and cognitive performance is the primary outcome. The trial expects that the supplemental Fe from the iron-fortified lentils will improve body Fe status and cognitive performance after controlling for baseline Fe status and dietary Fe intake in this group of adolescent girls. The secondary outcome is the participants' anthropometries. Considering the amount of plant protein from lentils that need to be consumed to for the study, it is expected to have significant improvement in growth of the participants which will lead to increased productivity.
This study provides participants with two diets that vary in their glycaemic index values (low vs. high), whilst also measuring cognitive performance and mood.
To evaluate the effect of dietary intervention on metabolic risk profile, and on potential simultaneous changes in physiological and cognitive functions and to collect a unique database using state-of-the-art technologies on variables related to the above mentioned areas.
The purpose of the present study is to determine the effects of eggs and egg components on cognitive performance and appetite in children aged 9-14 years, as well as to identify the underlying physiological mechanisms in this relationship.
Cognitive performance is negatively related to an impaired glucose metabolism, possibly due to impairments in brain vascular function. Supported by the statement from the American Heart and Stroke Association that physical exercise is one of the most effective strategies to protect against cognitive decline, we now hypothesize that exercise-induced changes in glucose metabolism cause beneficial effects on brain vascular function thereby improving cognitive performance. The primary objective of this intervention study is thus to evaluate in sedentary elderly men the effect of a 8-week aerobic-based exercise program on cerebral blood flow, as quantified by the non-invasive gold standard magnetic resonance imaging (MRI) perfusion method Arterial Spin Labeling (ASL). Cerebral blood flow is a robust and sensitive physiological marker of brain vascular function. Secondary objectives are to examine effects on glucose metabolism using the oral glucose tolerance test and cognitive performance as assessed with a neurophysiological test battery.
This project will assess the effects of the macro-nutrient make-up of morning food intake on cognitive performance using visual analog scale (VAS) measures, behavioral tests, and advanced high-density electrophysiological techniques (256-channel recordings). Two Isocaloric cereal products will be tested and compared to determine if measures of cognitive performance as well as satiety will change after consumption.
This study was designed to evaluate the chronic effects of a proprietary spearmint extract over 90 days of supplementation on aspects of cognitive performance (cognitive function and active reaction time), subjective mood, and sleep quality in healthy men and women.
