Journal of the International Society of Sports Nutrition, 2021 Background To achieve ideal strength/power to mass ratio, athletes may attempt to lower body mass through reductions in fat mass (FM), while maintaining or increasing fat-free mass (FFM) by manipulating their training regimens and diets.

Exercise in a metabolic chamber - Effects of exercise on 24 h fat oxidation
Journal of Physical Fitness and Sports Medicine, 2012 Indirect calorimetry with a room-size respiratory chamber provides an ideal setting to monitor energy metabolism for a prolonged period. During the last 10 years, experiments with this method have raised interesting observations such as: 1) exercise ...

Fat Oxidation Kinetics Is Related to Muscle Deoxygenation Kinetics During Exercise
Frontiers in Physiology, 2020 PurposeThe present study aimed to determine whether whole-body fat oxidation and muscle deoxygenation kinetics parameters during exercise were related in individuals with different aerobic fitness levels.MethodsEleven cyclists [peak oxygen uptake (V.O2p

Journal of Biological Research, 2014 The contribution of fat oxidation to energy production during exercise is influenced by intensity of exercise. The aim of this study was to assess the relationship between the highest value of fat oxidation rate (FATmax) and the oxygen uptake (VO2) in ...

Re-examination of the contribution of substrates to energy expenditure during high-intensity intermittent exercise in endurance athletes [PDF]
PeerJ, 2017 Background It has been believed that the contribution of fat oxidation to total energy expenditure is becoming negligible at higher exercise intensities (about 85% VO2max).

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Applied Model of Nutrient Oxidation in Male Broilers Reared under Different Temperatures
Jurnal Ilmiah Ilmu-Ilmu Peternakan, 2009 Effects of the environmental temperatures on nutrient oxidation were evaluated in male broiler chickens. The chickens were allocated into twelve cages with six chickens per cage during the first week and three chickens in the ...
