Substrate metabolism during different exercise intensities in endurance-trained women.
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...
متن کاملEffect of carbohydrate ingestion during exercise on post-exercise substrate oxidation and energy intake.
Thirteen physically active, eumenorrheic, normal-weight (BMI < 25 kg/m2) females, aged 18-30 years, completed 4 experimental conditions, with the order based on a Latin Square Design: (a). CHO/Ex: moderate-intensity exercise (65% VO2peak) with a net energy cost of approximately 500 kcals, during which time the subject consumed a carbohydrate beverage (45 g CHO) at specific time intervals; (b). ...
متن کاملImpact of Exercise and Moderate Hypoxia on Glycemic Regulation and Substrate Oxidation Pattern
OBJECTIVE We examined metabolic and endocrine responses during rest and exercise in moderate hypoxia over a 7.5 h time courses during daytime. METHODS Eight sedentary, overweight men (28.6 ± 0.8 kg/m2) completed four experimental trials: a rest trial in normoxia (FiO2 = 20.9%, NOR-Rest), an exercise trial in normoxia (NOR-Ex), a rest trial in hypoxia (FiO2 = 15.0%, HYP-Rest), and an exercise ...
متن کاملEffects of different carbohydrates and protein recovery mixtures on exogenous and endogenous substrate oxidation during subsequent exercise
Background A randomized, double-blind, placebo-controlled study was performed to evaluate the effect of adding protein (PRO) to a recovery mixture on exogenous and endogenous substrate oxidation during post-recovery exercise. Many studies have shown that carbohydrates (CHO) effectively restore glycogen post-exercise [1]. Some have also suggested that the addition of PRO to a CHO drink may produ...
متن کاملEffects of different protocols of hydration on cardiorespiratory parameters during exercise and recovery
INTRODUCTION Hydration plays a key role in the physiological maintenance required by exercise. OBJECTIVE To evaluate the behavior of heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure, pulse oxygen saturation (SpO2) and respiratory rate (RR) of young people during and after prolonged physical exercise, with and without the intake of water or isotonic solution. METHOD 31 youn...
