Filter by:Maximal fat oxidation during exercise (MFO) and the intensity of exercise that elicits MFO (Fatmax) has been recognized as potential determinants of endurance performance. The purpose of this study was to determine the possible interaction between the effects of diurnal variation (morning vs. afternoon) and caffeine ingestion on MFO, Fatmax and VO2 max in endurance-trained men. Specifically, the investigators sought to elucidate whether the stimulant actions of caffeine could reverse the decrements of MFO and Fatmax observed in the morning.
Lower extremity amputation causes rapid changes in musculoskeletal system. With the effect of these changes, the energy requirement for prosthetic ambulance is much higher than normal ambulance. Although methods such as the reduction of the segmental load of the prosthesis and the preference of the different prosthetic components for energy expenditure have been emphasized, the effect of exercise types has not been investigated in our knowledge. Therefore, the aim of the current study is to investigate the effect of spinal (Core) stabilization exercises on energy expenditure in combination with the classical physiotherapy program in patients with unilateral transtibial amputation. Individuals with transtibial amputation included in the study will be randomly divided into two groups. In group 1, basic exercises related to amputation will be applied for 8 weeks and in group 2 basic exercises with spinal stabilization exercises will be applied to the individuals. At the beginning and at the end of the exercise intervention, energy expenditure and exercise capacity will be evaluated by a portable exercise test device during '6 Minutes Step Test'; fatigue assessment will be done before and after 6 Minutes Step Test with 'Modified Borg Scale'; the strength of deep spinal muscles will be evaluated with 'Stabilizer'; dynamic balance and functional mobility will be evaluated by 'Timed Up & Go' Test; and the effect of the prosthesis on mobility will be evaluated by the sub-scale 'Mobility' of 'Prosthetic Evaluation Questionnaire'.
The three primary goals of this pilot will be followed by a secondary goal to test if dental intervention improves brain health in terms of sleep and cognition. The primary and secondary goals are 1. Explore the ratios of brain energy (ATP/PCr, Pi/PCr) and phospholipids (PME/PDE) metabolites as measured by magnetic resonance spectroscopy at 7 Tesla, and compare the differences in them with the performance of episodic memory, attention, language, and executive functions (abstraction, reasoning, verbal fluency, working memory) in three groups: cognitively normal adults, mild cognitive impairment (MCI) and Alzheimer's disease (AD). 2. Investigate the differences in sleep patterns measured by the ratio sleep quality index (Stable/ Unstable sleep) in cognitively normal adults, MCI and AD and its relation to the performance of episodic memory, attention, language, and executive functions (abstraction, reasoning, verbal fluency, working memory) in three groups. 3. Investigate the differences in the variations of two genes, APOE-E4 and ABCA7, in relationship to the changes in the brain energy metabolites and its relation to the performance of episodic memory, attention, language, and executive functions (abstraction, reasoning, verbal fluency, working memory) in those with cognitively normal adults, MCI and AD. 4. Investigate if dental intervention improves sleep patterns and overall cognitive behavior in the three cohorts.
Energy metabolism and insulin sensitivity were assessed in a case-control study in patients with branched-chain organic acidemias.
This study will explore differences in energy metabolism and metabolic flexibility under various conditions in older men and women.
This a randomized, double blind, placebo controlled, crossover design study which measures the effect of an available thermogenic dietary supplement on resting energy expenditure (REE), blood pressure and heart rate, and mood changes in moderate caffeine consumers. Participants will complete baseline measurements then ingest one of three pills. Once the pill is ingested, subjects will complete four REEs along with heart rate and blood pressure and appropriate questionnaires. Participants will return two more times, each after a one week washout period, and complete the same protocol with the remaining supplements.
We aim to examine energy metabolism in patients with pulmonary MAC and clarify the causes of emaciation. We will also investigate the following: the relation between energy metabolism and degree of pulmonary MAC progression; relations among hospitalization, mortality rate, and time-course of changes in energy metabolism; and factors that affect energy metabolism.
Comparison of Capsimax™ 2mg and 4mg of capsicum extract vs. placebo on metabolic rate and satiety.
The general objective of this project is to investigate the interplay of the gut microbiome - endocannabinoid axis with host environmental factors and intestinal, metabolic and mental health status in free-living adults with various metabolic statuses and lifestyles.
Co-administration of creatine and guanidinoacetic acid (GAA) has been recently put forward as an advanced dietary strategy to optimize tissue bioenergetics. The investigators hypothesized that creatine-GAA mixture would result in more powerful rise in brain and skeletal muscle creatine, as compared to creatine supplementation alone.
