Filter by:In this study, three-dimensional biomechanics , by means of lower limb joint angles and moments (opto-electronic system with synchronised force plate), of landing tasks (anticipated, unanticipated and cognitive dual task) before and after a mental fatigue protocol will be compared in a population of basketball, handball and volleyball players.
The aim of the study is to test a Fasting Mimicking Diet (FMD) for its efficacy on improving muscular resistance and endurance. The investigators will perform a randomized clinical trial to test the efficacy of the FMD on improving muscular strength, muscular resistance and endurance in physically active young adults (18-40 years of age). The study will include two arms: Placebo (Placebo diet) and FMD (3 cycles of 5-day fasting-mimicking diet within two months). Study endpoints will include muscular strength evaluation of lower limbs, cardio-pulmonary responses, neuromuscular function and muscle architecture. Subjects will be evaluated 4 times within 3 months: at baseline (T1), after the 1st cycle of diet (T2), 7 to 15 days after the 3rd cycle of diet maintaining baseline intensity (T3) and with re-assessment of Peak Power Output (T4).
Objective of the study The main objectives of this project are: 1. To assess the influence of mental fatigue on a return-to-play test battery in healthy population 2. To assess the influence of mental fatigue on brain functioning during a balance and reaction time task in healthy population In a later stage, these experiments could be carried out in a clinical context (e.g. in an ankle sprain population). The researchers will use a randomized, placebo controlled, counter-balanced, cross-over design. Thirteen healthy subjects will visit the lab 3 times. On the first visit (familiarisation trial), the investigators will collect the participants' characteristics. The participants will also be familiarized to the procedures and materials of the experiment during this first visit. The second and third visit contain the experimental setup and will proceed as follows: first, the participants will fill in a mental fatigue scale (M-VAS) and motivation scale. Next, the subjects will carry out a functional test battery (hop test, vertical jump test, Y-balance test, and a balance reaction-time test). Session rate of perceived exertion (RPE) is measured to indicate how fatigued the participants feel because of the test battery; also, M-VAS is collected once more. Then, a short cognitive task (Flanker task) is followed by either a long intensive cognitive task (90 minutes Stroop task) or control task (90 minutes documentary). Afterwards, participants have to carry out the Flanker task, fill in M-VAS (2x), perform the same test battery, fill in session RPE and one final fatigue scale (Nasa TLX). Heart frequency and EEG will be measured continuously during the trials.
The aim of this study is to demonstrate the effects of 28-days supplementation with a novel probiotic formulation on mental fatigue following a cognitive load in healthy adults. Half of the participants will receive the probiotic formulation while the other half will receive placebo.
The need for assisted-technology at home reflects some of the most serious health-related conditions faced by children with physical and developmental disabilities. 'Technology-dependent' is often used in the literature to describe children "who need both a medical device to compensate for the loss of a vital body function and substantial and ongoing nursing care to avert death or further disability". Parenting a child is stressful and challenging, and even under ideal circumstances the care of a child with complex needs requires greater than normal parenting skills. Studies have showed that parents of children whose illness require assisted-technology experience significant emotional stress, potential gaps in social support, and social isolation leading to lower quality of life, unhealthy family functioning, and negative psychological consequences. This study intends to assess the feasibility and efficacy of a tele-psychotherapy (Tele-P) intervention as a way to promote the emotional functioning of parents and to help increase the quality of life of children that are technology-dependent in the Greater Boston Area. It is hypothesized that parents who adhere to psychotherapy sessions via videoconferencing (Tele-P) will demonstrate significant reductions in symptoms of depression, anxiety and social isolation. Children of parents in the (Tele-P) condition will show significantly greater improvements in their quality of life including their physical health, mental health, family life, free time, and general life enjoyment. A randomized controlled trial is proposed in order to evaluate the feasibility and efficacy of a tele-psychotherapy intervention for parents of technology-dependent children at the Critical Care, Anesthesia and Perioperative Extension (CAPE) program in Boston Children's Hospital. This study will serve as model for social workers to perform an intervention for parent's raising technology-dependent children. This study proposes that tele-psychotherapy be a means of advocating for this underserved population.
This study aims at examining the influence of both physically and cognitively induced fatigue on trunk motor control on the one hand and brain activity related to movement preparation on the other hand, in healthy adult subjects. Furthermore, a comparison between the effects of both types of fatigue will be made. For this purpose a motor control task will be performed and compared before and after 3 specific interventions: i.e. a control intervention, a physical task and a cognitive task. Muscle and brain activity will be measured during each motor control task. It is hypothesised that motor control will not be altered after a control task, i.e. seated rest for 45 minutes. With regards to the physical fatigue condition, it is expected that trunk muscles will contract earlier after this task than before due to altered motor control. Cognitive fatigue is hypothesised to have similar underlying processes as physical fatigue, thus a similar earlier muscle contraction is also expected after cognitive fatigue. Lastly, as both types of fatigue are expected to induce a similar effect on motor control no significant differences between cognitive and physical fatigue are hypothesised. However, it is possible that the magnitude of this effect differs between types of fatigue, i.e. that 1 of both types has a bigger effect on motor control than the other. With regards to brain activity in preparation of a motor control task similar hypotheses are formulated: no effect of the control task on brain activity, earlier and possibly increased brain activity after both fatiguing tasks, and no differences between both types of fatigue besides a possible difference in magnitude of effect.
To assess the changes in brain activation and cerebral blood flow due to mental fatigue in a placebo-controlled study. More specifically we want to assess whether brain activation [measured with Blood Oxygen Level Dependent (BOLD) functional resonance imaging (fMRI)] is decreased during a Flanker task in a mentally fatigued state and whether this coincides with a decline in cognitive performance. In addition we also want to evaluate whether cerebral blood flow [measured with arterial spin labeled (ASL) fMRI] in a resting state is reduced when mentally fatigued.
This is a cross-over design study in which subjects arrived to the lab and were assigned a supplement to ingest. Prior to ingestion subjects completed baseline reaction time testing along with a questionnaire. Thirty minutes after ingestion subjects filled out the same questionnaire, completed a reaction time test, followed by a series of dynamic exercises. After the last exercise was finished subjects filled out the questionnaire, completed another reaction time test and repeated the series of dynamic exercises. Following the exercises, subjects filled out the questionnaire and completed a fourth round of reaction time testing. In total subjects would complete 2 rounds of dynamic exercises and 4 rounds of reaction time testing with heart rate being recorded before and after the dynamic exercise rounds. Subjects were told to wash-out for 7 days and return to the lab to complete the same testing but on the alternative supplement.
The purpose of the study is to determine if temporarily relocating clinicians who deliver remote care using the eICU telehealth system to Sydney, Australia will lead to greater job satisfaction, reduced physiologic stress, and improve performance. Four nurses and six physicians will be sent to a site in Sydney Australia on a rotating basis to determine whether providing care during the Australian daytime is more efficient and precise than providing care during the night in the United States.
The current study is design to asses the effect of E-AG-01/ E-AG-02/ E-AG-03 on mental alertness as compared to placebo.
