It is well known that globally, school-based fortification and school feeding approaches have been applied to remedy nutritional deficiencies that impact health in the primary school age group. Aim of the study: to produce a fortified biscuit with chickpea and crushed peanut. To evaluate the effectiveness of the fortified biscuits intake for 4 months in terms of its acceptability and impact on cognitive performance for a sample of children aged 8-12 years attending rural primary schools in an Egyptian village. The fortified biscuits' effect on auditory attention, visual and working memory, and learning ability was evaluated. Methodology: This study was an interventional study conducted in two stages: stage one was the production of nutritious biscuits that is based on chickpea flour and peanut in addition to whole wheat (extract 72 %), wheat germ, cinnamon, milk, and egg. All these constituents help in enhancing immunity, fighting viruses, maintaining regular and healthy bowel movement, regulating blood sugar and cholesterol levels, and more importantly improving the cognitive abilities of school-aged children. During stage two, eighty Children were randomly allocated in either chickpea and peanuts biscuits dependent group (40 children) or non-dependent group (40 children) to evaluate the impact of the fortified biscuits. All enrolled children and their mothers received 5 cognitive stimulation sessions over four months. The cognitive performance of primary school-aged children was assessed before and after the interventions by a battery of four verbal & non-verbal intelligence psychological tests. These tests covered short-term and working memory, visual memory, and the ability for categorization, learning for speed of information processing, and auditory attention ability with rising levels of difficulty. These tests were: Digit Span, the figural memory tests, Coding and Auditory vigilance tests A and B respectively. Five items were used to evaluate the physical characteristics of the biscuits: color, odor, taste, consistency, and general acceptance.
The objective of the study is to evaluate the cognitive performance of 4 chocolate milk drinks.
The current clinical study will have two groups of participants (young adults ages 20 - 30, and older adults ages 60 - 70) take part in three visits to the lab. On the first visit participants will fill out questionnaires assessing demographics and physical activity level. On the 2nd and 3rd visits participants will be engage in both a moderate intensity bout of aerobic exercise for 20 minutes, and 20 minutes of resting on a stationary bike watching an educational video. These two visits will be counterbalanced across age groups. Following both the exercise bout and the resting control condition participants will complete cognitive tasks assessing episodic memory and executive functioning. The first hypothesis is that older adults who are more physically active (assessed via questionnaire) will have significantly greater cognitive abilities compared to those who are less active or sedentary. The second hypothesis is that following a single bout of moderate intensity aerobic exercise, older adults will have a greater magnitude of change in their short-term memory, and long-term memory performance compared to younger adults.
The objective of the study is to evaluate the glycemic index and glycemic load of 4 chocolate milk drinks.
The aim of the current study is to evaluate under blinded conditions, both in a simulated environment and during helicopter flight, the effect of a rapid (within 20 minutes) exposure to altitude (4000 m asl) on physiological parameters and selected cognitive domains, in providers operating in helicopter emergency medical service (HEMS) exposed to hypobaric hypoxia or to hypobaric normoxia (H0: cognitive effects under hypobaric hypoxia = cognitive effects under hypobaric normoxia). Simulated environment will allow to control different factors. The parallelism between a study branch conducted in a simulated environment and another one conducted under a real-life condition will allow to evaluate the additive effects on additional stressor factors (processive and systemic ones). - Simulation branch: each participant will take part in three research sessions: a familiarization session and two experimental sessions in simulation facility called terraXcube (test 1 and 2). On test 1 and test 2 each group will be exposed twice to the simulated altitude of 4000 m asl (under hypobaric hypoxia or hypobaric normoxia conditions) according to the randomization protocol. Participants will perform the neurocognitive tests three times on each of the two tests: before the ascent (TC0), after 5 min from the end of the ascent (TC1) and after around 30 min (TC2), to investigate European Union Aviation Safe Agency (EASA) proposed recommendations. After completing each neurocognitive test session, participants will be asked to rate their performance using a visual analogue scales (VAS). All participants will wear the vital parameters monitoring system during the entire duration of the tests inside the chamber, as well as the cerebral oxygen saturation (ScO2) sensor. Samples will be collected by saliva, urine and/or capillary blood. The same schedule is repeated in each test session. - In-field branch: each participant will take part in three research sessions: a familiarization session and two experimental sessions during helicopter flights (test 1 and 2). On test 1 and test 2 each group will be exposed twice to the altitude of 4000 m (under hypobaric hypoxia or hypobaric normoxia conditions) according to the randomization protocol. Participants will perform the neurocognitive test two times on each test: before the ascent (TC0), after around 5 min from the end of the ascent (TC1). After completing each neurocognitive tests, participants will be asked to rate their performance using a visual analogue scales (VAS). All participants will wear the vital parameters monitoring system during the entire duration of the tests. Samples will be collected. The same schedule is planned in each test session.
The primary objective is to assess the impact of two nutritional interventions vs. placebo on objective and subjective sleep measures in athletes. Participants receive one beverage on each of three consecutive nights in a randomized manner. It is hypothesized the two nutritional interventions will result in significant improvements in sleep onset latency, and will not result in a negative impact on next-day cycling performance. The secondary objective is to assess the impact of the nutritional interventions vs. placebo on next-morning performance (physical, cognitive function, and balance).
The primary purpose is to test the short-term effects of the acute consumption of two novel beverages made from coffeeberries, the fruit of the coffee plant (Coffea arabica) benchmarked against caffeine on several aspects of cognitive performance. Preliminary studies suggest that flavanols and chlorogenic acids can enhance cognitive performance. It is unknown if drinks formulated with flavanols and chlorogenic acids (without high sugar or caffeine) improve cognition or mood to a similar extent as caffeine. Coffeeberry beverage comparisons will be made to a flavored positive control beverage containing caffeine and a flavored placebo beverage.
This study investigates the effects of extended-duration spaceflight (12-month International Space Station missions) on general cognitive performance (measured with the Cognition test battery), spatial cognition, structural and functional brain changes in general, and hippocampal plasticity more specifically relative to the shorter 6-month and 2-month missions.
