Gender Based Differences in Fuel Metabolism in Response to Long Duration Exercise

Difference in long-term movement based on sex in fuel metabolism The purpose of this study was to determine gender-based differences in fuel metabolism to cope with long-term exercise. To put it another way, it is a simple question. . . Which gender will metabolize more fat and carbohydrates at the same relative intensity level? Fuel metabolic reactions during exercise were compared in samples of two men and 13 females at 2 hours (40% of maximum intake) and 2 hours later.

The problem of fuel source for muscle oxidation during exercise was solved. A review of the experiment over 60 years supports the notion that the main energy sources for exercise metabolism are fat and carbohydrate oxidation. The relative contribution of these major substrates to systemic metabolism depends on such factors as the strength and duration of exercise, the meals consumed during the first few days of exercise, and the state of physical training. For gentle, long-term exercise, fat consumption will gradually increase until accounting for up to 80% of total caloric expenditure. However, as exercise intensity increases, the relative contribution of fat to metabolism is small, and the relative contribution of carbohydrates is greater. Eating a rich diet with fat and protein will increase the amount of fat used while reducing the strength and duration of sustainable efforts.

An increase in mitochondrial density can be thought of as skeletal muscle and metabolic adaptation. One focus of metabolic adaptation is fat metabolism fuel during exercise. Due to the nature of high intensity exercise, the effectiveness of this type of fat burning training is carefully studied. Perry et al. (2008) After interval training for 6 weeks, fatty oxidation or fat burning was much higher and carbohydrate oxidation (combustion) showed a considerable decrease. Again, in only two weeks Talanian et al. (2007) It shows an important change in HIIT fatty acid oxidation. Horowitz and Klein (2000) concluded that in the study of their studies, the increase in fatty acid oxidation is a remarkable indication observed in continuous endurance exercise.

This review outlines a marked decrease in carbohydrate intake, resulting in metabolism from 'glucose center' (glucose) to 'fat center' (keto body, fatty acid) (8). The main fuel sources are fatty acids (from dietary fat and fat storage) and ketones (from dietary fat, protein and fat storage) (Table 1). Glucose-dependent tissues (ie red blood cells, retina, lens, and renal medulla) receive glucose via gluconeogenesis and glycogenolysis. (It is estimated that liver and kidney can produce 200 g / day of glucose from dietary protein and fat, even if dietary carbohydrates are not consumed.) The metabolic conditions experienced by people following LCKD are usually starvation It is related to. Endogenous sources (muscle proteins, glycogen, fat storage, etc.) are used as an energy source under starvation conditions (10).
