the present study aimed to compare substrate oxidation and total energy expenditure during running with low and moderate intensity until exhaustion and one hour after exercise in obese male students. for this purpose, in a crossover study design, 11 male university students (mean age 20.45±1.69 years, bmi 31.26±1.3 kg/m2, body fat percentage 28.47±3.53 %) participated in this study. two exercis...

This study compared fat oxidation rate from a graded exercise test (GXT) with a moderate-intensity interval training session (MIIT) in obese men. Twelve sedentary obese males (age 29 ± 4.1 years; BMI 29.1 ± 2.4 kg·m(-2); fat mass 31.7 ± 4.4 %body mass) completed two exercise sessions: GXT to determine maximal fat oxidation (MFO) and maximal aerobic power (VO2max), and an interval cycling sessio...

conclusions according to the results of the present study, aerobic exercise at moderate intensity and proper time can be considered as a special treatment to prevent diabetes complications and related disorders, particularly obesity. objectives this study aimed to determine whether in patients with type 2 diabetes, substrate oxidation and energy expenditure were affected by the type of intensit...

SUMMARY The purpose of this study was to investigate differences in fat metabolism between visceral fat obese (VF-Ob) and abdominal subcutaneous obese (SF-Ob) men during "high-intensity endurance exercise". Fourteen obese (body mass index >25 kg/m(2)) men were classified into two groups according to visceral fat area using computed tomography; i.e., VF-Ob (n = 7; mean age, 52.0 ± 2.5 year) and ...

fat oxidation during exercise can be influenced by exercise intensity and duration, training status, diet and physical activity level. however, few studies have investigated the effect of time of day on the rate of fat oxidation during exercise. thus the present study was designed to investigate the effect of time of day on indexes of fat oxidation in active young women. for this purpose, 14 he...

Acute exercise has been shown to attenuate postprandial plasma triglyceride elevation (PPTG). However, the direct contribution of exercise intensity is less well understood. The purpose of this study was to examine the effects of exercise intensity on PPTG and postprandial fat oxidation. One of three experimental treatments was performed in healthy young men (n = 6): nonexercise control (CON), ...

We have studied eight endurance-trained women at rest and during exercise at 25, 65, and 85% of maximal oxygen uptake. The rate of appearance (R(a)) of free fatty acids (FFA) was determined by infusion of [(2)H(2)]palmitate, and fat oxidation rates were determined by indirect calorimetry. Glucose kinetics were assessed with [6,6-(2)H(2)]glucose. Glucose R(a) increased in relation to exercise in...

This study determined the effect of carbohydrate ingestion during exercise on the lipolytic rate, glucose disappearance from plasma (Rd Glc), and fat oxidation. Six moderately trained men cycled for 2 h on four separate occasions. During two trials, they were fed a high-glycemic carbohydrate meal during exercise at 30 min (0.8 g/kg), 60 min (0.4 g/kg), and 90 min (0.4 g/kg); once during low-int...

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 ...
