CHANGES IN METABOLIC EFFICIENCY IN SKILLED ATHLETES DURING INTENSE EXERCISE

The body’s predominant choice of substrates and the rate their oxidation in working muscle are largely influenced by physical activity intensity. higher intensity work, more important role energy supply processes played carbohydrates. It is suggested that ability to most effectively use fat as an substrate at rest during exercise allows athletes save carbohydrates perform high-intensity work. This study investigated efficiency metabolism skilled increasing 99 body composition assessments (via bioelectrical impedance) incremental tests using a gas analysis system were performed 90 male national- international-level (age 16-35 y.o.) sports related endurance combat sports. respiratory exchange ratio significantly correlates with values when reaching anaerobic threshold ((r = 0.52, р ≤ 0,05)) maximum oxygen consumption (r -0.26, 0,05). oobtained data shows efficient resting creates preconditions for intense activity. informative indicator metabolism, which can be used complex control functional condition athlete.
