Association of Fat Oxidation and Insulin Resistance in Prepubertal Children
Identifying the relationship between fat oxidation and insulin resistance (IR) may provide vital clues to the mechanisms behind the development of metabolic disease in prepubertal children. The purpose of this study was to examine the association of fat oxidation with insulin resistance (IR) and …

The Effect of Moderate Physical Activity on Resting Fat Oxidation
… CDC/ACSM recommendation) on the resting level of fat oxidation. It was hypothesized that a 30-minute treadmill walk at 50% VO 2peak performed in late afternoon would not increase fat oxidation the following morning (12 hours after the end of the treadmill walk). It was also hypothesized that a …

Optimizing the food guide pyramid to increase fat oxidation in young adult men
… blood glucose and insulin levels and increase fat oxidation (FOX) compared with a diet consisting of higher GI foods. Secondly, I tested the hypothesis that variability in resting FOX would predict FOX during moderate exercise after consuming the lower and higher GI diets. Lower and higher GI …

The impact of carbohydrate ingestion on the regulation of fat oxidation following exercise
… carbohydrate (CHO)ingestion on the regulation of fat oxidation following glycogen lowering exercise. Methods: Six males (age 23.4 2 1.7y, vo2peak 58.0 2 2.1 ml.kg-'.min-') participated in the study. Subjects performed an incremental maximal cycle ergometer test and a verification trial to …

Fat oxidation at rest and during exercise in postmenopausal middle eastern and white women
… alteration in body composition. Differences in fat oxidation rates (FOR) have been observed between ethnic groups and the hormonal modifications that occur after menopause have been speculated to influence these differences. Only select ethnic groups have been studied, and exploring additional …

The Effects of Walking on the Alter-G® Treadmill on Fat Oxidation in Overweight/Obese Males
… peak oxygen consumption (V̇O<sub>2peak</sub>), fat oxidation (FO), peak fat oxidation (PFO), respiratory exchange ratio (RER), heart rate (HR) and rate of perceived exertion (RPE) in overweight and or obese men. <strong>Methods: </strong>Fourteen, overweight and obese men (mean age 23.2 ± 2.4 …

Determinants of maximal fat oxidation during exercise in healthy adults and individuals with type 2 diabetes mellitus
… de grasa (MFO) y la intensidad a la cual ocurre (Fatmax). Además, los determinantes de la oxidación de grasa están asociados con factores no modificables, como la edad y el sexo, así como con factores modificables, incluidos la composición corporal, la capacidad cardiorrespiratoria (CRF), la …

Association between the gut microbiota profile, fat oxidation capacity during exercise, and leptin sensitivity in patients with type 2 diabetes mellitus: The Edugution Project
… with T2D experience difficulties in the oxidation of fats and glucose, a phenomenon known as metabolic inflexibility, which negatively impacts their body composition and overall metabolic health. As maximal fat oxidation (MFO) is typically assessed with protocols requiring two separate …

Skeletal Muscle Substrate Metabolism following a High Fat Diet in Sedentary and Endurance Trained Males
… by the resistance to switching substrate oxidation preference based on substrate availability and can be measured in either fasted or insulin-stimulated conditions. As the largest site for glucose disposal and a primary tissue influencing regulation of blood glucose concentrations, …

Carbohydrate Supplementation During Prolonged Aerobic Exercise for People Living with Type 1 Diabetes on Insulin Pump Therapy: The ExCarbs Study
… increased ketones (0.4 0.3 mmol/L), increased fat oxidation (0.51 0.2 g/min), and increased glucagon (30.9 22.3 pg/mL) at exercise end, compared to arm 1 (all P < 0.05). All strategies had minimal hypoglycemia throughout exercise, with arm 2 having increased fat oxidation and improved …

The nature of cachexia in patients with heart failure and stable coronary artery disease
… lower body mass index (BMI) and percentage body fat than all the other subject groups. In contrast, there was no significant reduction in fat free mass index (FFMI). In addition, the HF-cachexia group had higher rates of fat oxidation than all other groups. While the HF-cachexia group had …

What goes down need not go back up: decreasing the biological drive toward weight regain by increasing energy flux
… to LF (1847±126 kcal/day; P = 0.05). Resting fat oxidation was also higher during HF (0.073+0.010 g/min) compared to LF (0.059+0.012 g/min; P<0.05). Average daily, perceived end-of-day hunger was lower during HF compared to LF (P<0.05). CONCLUSION: These preliminary data suggest that compared …

Endogenous glucose production and gluconeogenesis during exercise in athletes on either a low-carbohydrate or mixed diet
… and liver glycogen content, increased rates of fat oxidation and decreased rates of carbohydrate (CHO) oxidation. Despite reduced CHO availability, the rate of CHO oxidation that can be sustained during exercise in LCHF athletes is surprisingly high. The most probable source of this glucose is …

Effects of exercise, with and without an associated energy deficit, on postprandial metabolism and appetite regulation
… arterial stiffness and increasing postprandial fat oxidation. It also appears that exercise might facilitate a tighter coupling between energy intake and expenditure, mediating more stable and healthy body weights, perhaps by inducing changes in appetite, energy intake and circulating …

The role of metabolic rate and substrate utilization in the maintenance of body weight, body composition and insulin sensitivity
… that target the reduction of body weight and fat mass. The improvement of cardiorespiratory fitness (CRF), metabolic flexibility and insulin sensitivity also contribute towards reducing obesity-associated risk factors. While energy restriction alone results in significant weight loss, …

Fat storage in athletes : the metabolic and hormonal responses to swimming and running exercise
… to store significantly greater amounts of body fat than competitive runners. In an attempt to explain these discrepancies, male collegiate swimmers (n=8) and runners (n=8) were monitored during 45 min of swimming and running, respectively (75% V02 max), and during two hours of recovery. In …

Examining Sex Differences in Substrate Utilization During Threshold-Based Exercise Prescription
… metabolic stress and ratios of carbohydrate to fat oxidation that result in a lower steady-state respiratory exchange ratio (RER) in females. Differences in exercise response may be explained by differences in metabolic stress and muscle oxygenation linked to sex-based differences in lactate …

The Role of Fasting Acylcarnitines in Metabolic Flexibility from Short Term High Fat Feeding
… a hindered ability to properly transition from fat oxidation while in a fasted state to carbohydrate oxidation once fed, leading to a buildup of mitochondrial metabolites such as acylcarnitines. Carnitine, essential for fatty acyl-CoA transport through the inner and outer mitochondrial …
