The current study examined the effect of sprint interval exercise on postexercise oxygen consumption, respiratory-exchange ratio (RER), substrate oxidation, and blood pressure in adolescents. Participants were 10 normal-weight healthy youth (7 female), age 15-18 years. After overnight fasts, each participant undertook 2 trials in a random balanced order: (a) two 30-s bouts of sprint interval ex...

CrossFit is a metabolically demanding strength and conditioning method which performance may benefit from a carbohydrate (CHO)-rich diet. This study investigated the effect of three consecutive days of high CHO intake on CrossFit performance and corresponding metabolically -related variables in strength trained individuals. Eighteen subjects with a CHO intake of <6 g/kg/day were randomly assign...

BACKGROUND/OBJECTIVE We assessed the metabolic and heart rate (HR) responses to a single session of circuit resistance training (CRT) in six subjects with complete paraplegia (T5-T12 levels) in order to determine the caloric cost of the exercise. METHODS Subjects underwent isoinertial weight training exercises with interspersed periods of high-cadence, low-resistance arm ergometry (AE). Follo...

Methods Twenty-two males (n = 13) and females (n = 9) ages 20– 36 years (23.68 +/3.91), volunteered as subjects. Each subject performed two VO2max treadmill tests within two weeks of each other. Administration of the trials was double-blinded and randomized with half of the participants ingesting PRX1 during the first trial and PRX2 during their second trial with the product order being reverse...

This study examines the growth effects of real exchange rate (RER) misalignment and capital flight in Turkey during period 1981-2019. The World Bank’s residual method suggests that is a widespread problem Single Equation Approach adopted to delineate series RER identifies Turkey’s significantly misaligned throughout sample period. Their are then examined using autoregressive distributed lag (AR...

IL-6 is produced and released in large amounts from skeletal muscle during prolonged exercise in both mice and humans, but there are few data indicating the biological significance of this. IL-6 exerts metabolic effects such as stimulating energy expenditure and reducing body fat mass. We have now investigated the effects of IL-6 deficiency on exercise endurance and energy expenditure in preobe...

The purpose of this study was to determine what effects 26 wk of resistance training have on resting energy expenditure (REE), total free-living energy expenditure (TEE), activity-related energy expenditure (AEE), engagement in free-living physical activity as measured by the activity-related time equivalent (ARTE) index, and respiratory exchange ratio (RER) in 61- to 77-yr-old men (n = 8) and ...

BACKGROUND To determine the acute effects of ingesting a thermogenic drink (Celsius, Delray Beach, FL) (TD) on changes in metabolism and lipolysis. METHODS Healthy college-aged male (23.2 +/- 4.0 y, 177.2 +/- 6.1 cm, 81.7 +/- 11.3 kg, 22.8 +/- 7.3 % fat; n = 30) and female (23.4 +/- 3.1 y, 165.6 +/- 8.7 cm, 62.1 +/- 9.9 kg, 28.3 +/- 7.4 % fat; n = 30) participants were matched according to he...

The objectives of the pilot study are to (1) confirm the general observation that an immune-supporting supplement, ASEATM, has an effect on athletic performance and (2) determine the specific physiological parameters: Heart Rates (HR), volume of O2 inspired (VO2), volume of CO2 expired (VCO2), volume of expired gas (VE), Respiration Rate (RR), Respiratory Exchange Ratio (RER), Aerobic Threshold...
