Filter by:This trial investigated the impact of providing a regular meal with and without additional multiple micronutrients for children in Northwest Pakistan on their performance at school, in comparison to a local government school that served as a control i.e. no school meal.
This study examines the effectiveness of a biodynamic lighting intervention on the sleep, cognitive functions, and alertness of adults working from home. The biodynamic intervention is an innovative lighting solution that intends to harness both visual and non-visual effects of lighting through delivering varying intensities and spectra during working hours according to a preset protocol.
Dehydration lowers both physical and mental performance if it is severe enough. Performance declines are more pronounced in hot conditions or after prolonged strenuous activity such as exercise. Most individuals drink less than their sweat losses during activity, while some individuals overdrink and develop a sodium deficiency. Water and electrolyte balance must be restored as part of the recovery process after any activity that causes sweating. Plain water causes a decrease in plasma sodium concentration and osmolality, which reduces the desire to drink and increases urine production. Unless the volume ingested exceeds the loss, individuals are in net negative fluid balance throughout the recovery period due to urinary losses. When sodium and potassium are added to rehydration fluids, urine production is reduced in the hours following rehydration. Rehydration is only possible if a volume of fluid equal to or greater than the amount lost through sweat is consumed, together with adequate electrolytes. The test products for this study, TP1 and TP2, are novel hydration beverage formulas. They are an electrolyte drink mixture with five essential vitamins and three times more electrolytes than typical sports beverages. The test products create an osmotic force that permits water to be supplied to the bloodstream sooner in the digestive system by using a specific ratio of sodium, glucose, and potassium. This randomized, placebo-controlled, semi-blind, crossover study will evaluate the effects of the test products on rehydration in healthy adults.
The aim of the clinical trial is to evaluate the efficacy of two novel hydration products on rehydration following exercise.
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).
