trotzdem hoffe ich, dass jetzt niemand frustriert ist, vor allem nicht die weiblichen forumels unter uns :winke:.
erstens gibt es auch studien, die sehr wohl eine nachhaltige steigerung der RMR (und die ist ja gleichbedeutend mit der fettverbrennung in ruhe) ergeben haben (ich habe ein paar davon schon im forum präsentiert).
und zweitens treiben wir ja sport aus freude an der sache und nicht im ständigen bewusstsein an den kalorienverbrauch, stimmt's leute? :winke:
gruss an alle,

Effect of exercise training at different intensities on fat metabolism of obese men.
Van Aggel-Leijssen DP, Saris WH, Wagenmakers AJ, Senden JM, Van Baak MA. Department of Human Biology, Nutrition, Toxicology, and Environmental Research Institute, Maastricht University, 6200 MD Maastricht, The Netherlands.
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 nonexercising control group. Before and after the intervention, measurements of fat metabolism at rest and during exercise were performed by using indirect calorimetry, [U-(13)C]palmitate, and [1,2-(13)C]acetate. Furthermore, body composition and maximal aerobic capacity were measured. Total fat oxidation did not change at rest in any group. During exercise, after low-intensity exercise training, fat oxidation was increased by 40% (P < 0.05) because of an increased non-plasma fatty acid oxidation (P < 0.05). High-intensity exercise training did not affect total fat oxidation during exercise. Changes in fat oxidation were not significantly different among groups. It was concluded that low-intensity exercise training in obese subjects seemed to increase fat oxidation during exercise but not at rest. No effect of high-intensity exercise training on fat oxidation could be shown.

Effects of endurance and resistance training on total daily energy expenditure in young women: a controlled randomized trial.
Poehlman ET, Denino WF, Beckett T, Kinaman KA, Dionne IJ, Dvorak R, Ades PA. Divisions of Clinical Pharmacology and Metabolic Research and Cardiology, Department of Medicine, University of Vermont, Burlington, Vermont 05405.
There exists considerable controversy regarding the impact of different modes of exercise training on total daily energy expenditure (TEE). To examine this question, young, nonobese women were randomly assigned to a supervised 6-month program of endurance training, resistance training, or control condition. TEE was measured before and 10 d after a 6-month exercise program was completed with doubly labeled water. Body composition was determined from dual energy x-ray absorptiometry, maximum aerobic capacity from a treadmill test to exhaustion, and muscular strength from one-repetition maximum tests. Results showed that body composition did not change in endurance-trained women, but maximum aerobic capacity increased by 18%. Resistance-trained women increased muscular strength and fat-free mass (1.3 kg). TEE did not significantly change when measured subsequent to the endurance or resistance training programs. Absolute resting metabolic rate increased in resistance-trained women but not when adjusted for fat-free mass. No change in physical activity energy expenditure was found in any of the groups. These results suggest that endurance and resistance training does not chronically alter TEE in free-living young women. Thus, the energy-enhancing benefits of exercise training are primarily derived from the direct energy cost of exercise and not from a chronic elevation in daily energy expenditure in young, nonobese women.
