The purpose of present study was to compare fat oxidation rate during and after three different exercise intensities. Eight non-athlete male students (aged, 19.7±1.8 yr; height, 174.3±5.1 cm; weight, 64.5±7 kg; VO max, 40.1±4.4 ml/kg/min) participated in this study as subjects. Each subject was exercised at 55, 65 and 75% 2 VO max on treadmill at three separate days those days which elapsed by ...

The first aim of this study was to determine the exercise intensity that elicited the highest rate of fat oxidation in sedentary, obese subjects (OB; n=10 men, n=10 women) compared with endurance athletes (AT; n=10 men, n=10 women). The second aim was to investigate the relationship between VO2 at the intensity eliciting the highest rate of fat oxidation and the corresponding VO2 at the lactate...

The present study investigated the effect of exercise training at different intensities on fat oxidation in obese men. Twenty-four healthy male obese subjects were randomly divided in either a low- [40% maximal oxygen consumption (VO(2 max))] or high-intensity exercise training program (70% VO(2 max)) for 12 wk, or a non-exercising control group. Before and after the intervention, measurements ...

Aim: Fat oxidation is impaired in obesity. The aim of this study was to determine if fat oxidation, seen in a high protein meal response, was influenced by body composition. Methods: Subjects were provided with control (14% protein, glycemic index, GI 65), high protein high GI (33% protein, GI 74), and high protein low GI (35% protein, GI 45) meals. Substrate oxidation and energy expenditure we...

This study aimed to compare fat oxidation, hormonal and plasma metabolite kinetics during exercise in lean (L) and obese (O) men. Sixteen L and 16 O men [Body Mass Index (BMI): 22.9 ± 0.3 and 39.0 ± 1.4 kg · m(-2)] performed a submaximal incremental test (Incr) on a cycle-ergometer. Fat oxidation rates (FORs) were determined using indirect calorimetry. A sinusoidal model, including 3 independen...

background the purpose of this study was to determine appropriate intensity of activity with fatmax during incremental exercise in the active and sedentary male participants. material and methods in this study, 11 active male students(vo2max42.87±1.75ml.kg-1.min-1,bmi 21.40±1.01 kg.m2) and 9 sedentary male students(vo2max36.57±2.95ml.kg-1.min-1, bmi 24.28±1.83kg.m2) were selected as the active ...

Whole body fat oxidation increases during exercise. However, 24-h fat oxidation on a day with exercise often remains similar to that of sedentary day, when energy intake is increased to achieve an energy-balanced condition. The present study aimed to examine a possibility that time of the day when exercise is performed makes differences in 24-h fat oxidation. As a potential mechanism of exercis...

Acute high-fat (HF) diets can lead to short-term positive fat balances until the body increases fat oxidation to match intake. The purpose of this study was to examine the effects of a HF diet, rich in either mono-unsaturated or saturated fatty acids (FAs) and exercise, on the rate at which the body adapts to a HF diet.(13)C-labeled oleate and (2)H-labeled palmitate were also given to determine...

In a previous study, we showed that lean subjects are capable of rapidly adjusting fat oxidation to fat intake on a high-fat (HF) diet when glycogen stores are lowered by exhaustive exercise. However, it has been proposed that obese subjects have impaired fat oxidation. We therefore studied the effect of low glycogen stores on fat oxidation after a switch from a reduced-fat (RF) diet to an HF d...

Smen is a milk fat isolated by ‘boiling-off’ water. Milk fat was first converted into butter and then into smen. Smen product is utilized for culinary cooking and frying of different food. Smen has better shelf-life than other indigenous dairy products due to its lower moisture content. However, it undergoes deterioration (lipolysis and oxidation of milk fat) causes flavor impairment, lowers nu...
