Despite the recent studies on structural and functional adaptations of the right ventricle (RV) to exercise training, adaptations of its metabolism remain unknown. We investigated the effects of short-term, high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on RV glucose and fat metabolism. Twenty-eight untrained, healthy 40-55 yr-old-men were randomized i...

This study evaluated the effects of 6 weeks of high-intensity interval training (HIIT) on mechanical efficiency (ME) in young and older groups. Seventeen healthy young adults [26.2(2.4) year], and thirteen healthy older adults [54.5(2.3) year] completed a 6-week HIIT intervention (three sessions per week) on an electromagnetically braked cycle ergometer. Each HIIT session contained six repetiti...

BACKGROUND Aerobic exercise has a marked impact on cardiovascular disease risk. Benefits include improved serum lipid profiles, blood pressure and inflammatory markers as well as reduced risk of stroke, acute coronary syndrome and overall cardiovascular mortality. Most exercise programs prescribed for fat reduction involve continuous, moderate aerobic exercise, as per Australian Heart Foundatio...

Similar to muscles, the intestine is also insulin resistant in obese subjects and subjects with impaired glucose tolerance. Exercise training improves muscle insulin sensitivity, but its effects on intestinal metabolism are not known. We studied the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on intestinal glucose and free fatty acid upta...

Background: Adipose tissue pathology plays a crucial role in the pathogenesis of type 2 diabetes mellitus. Understanding impact exercise training on adipose adaptation is paramount importance enhancing metabolic health. In this study, we aimed to investigate effects various modalities three distinct depots, namely, interscapular brown (iBAT), subcutaneous white (sWAT), and epididymal (eWAT), mu...

Previous studies have investigated the effects of high-intensity interval training (HIIT) on cardiorespiratory fitness and body composition in overweight populations. However, short-term effect HIIT free fatty acids (FFA) serum women sedentary lifestyle is not clearly understood. The aim this study was to investigate 2-week high intensity fat percentage, acids, VO2max adult women. fourteen youn...

objective(s):high-intensity interval training (hiit) increases energy expenditure and mechanical energy efficiency. although both uncoupling proteins (ucps) and endothelial nitric oxide synthase (enos) affect the mechanical efficiency and antioxidant capacity, their effects are inverse. the aim of this study was to determine whether the alterations of cardiac ucp2, ucp3, and enos mrna expressio...

BACKGROUND Evidence of the efficacy of high-intensity, low-volume interval training (HIIT-low volume) in treating insulin resistance (IR) in patients with metabolic disorders is contradictory. In addition, it is unknown whether this effect is mediated through muscle endocrine function, which in turn depends on muscle mass and fiber type composition. Our aims were to assess the efficacy of HIIT-...
