This study was to determine the effects of five-week high-intensity interval training (HIIT) on cardiorespiratory fitness, body composition, blood glucose, and relevant systemic hormones when compared to moderate-intensity continuous training (MICT) in overweight and obese young women. Methods. Eighteen subjects completed 20 sessions of HIIT or MICT for five weeks. HIIT involved 60 × 8 s cyclin...

Background. Because VO2max doesn’t provide any detailed information about aerobic examinations Oxygen Kinetic is used for more accuracy. Long intensive and repetitive exercises with sufficient time lead to increase in aerobic parameters like kinetic absorption of oxygen. Objectives. The purpose of this study was to determine time dependent effects of short-time high intensity interval...

The purpose of this randomized controlled clinical trial was to determine the effect of a 14-week high-intensity interval training (HIIT) intervention with weight stability on metabolic flexibility, insulin sensitivity, and cardiorespiratory fitness in sedentary, premenopausal, nondiabetic, overweight/obese African American women. Twenty-eight subjects were allocated to one of two groups: HIIT,...

Muscle atrophy is one of the consequences of aging and sports activities may prevent it. The aim of this study was to evaluate the effect of high intensity interval training on gene expression of Tweak and Fn14 in EDL muscle of aged C57bl/6 mice. For this purpose, 28 male C57bl/6 mice aged (n=14) and adult (n=14) were assigned in two groups of training (n=7) and control (n=7). After one-week fa...

AIMS High-intensity interval training (HIIT) improves peak oxygen uptake and left ventricular diastology in patients with heart failure with preserved ejection fraction (HFpEF). However, its effects on myocardial strain in HFpEF remain unknown. We explored the effects of HIIT and moderate-intensity aerobic continuous training (MI-ACT) on left and right ventricular strain parameters in patients ...

The purposes of our study were to examine (1) Rh B glycoprotein (Rhbg) and Rh C glycoprotein (Rhcg) expressions in mouse skeletal muscle; and (2) the effect of 6-week training on Rhbg and Rhcg expressions. The levels of Rhbg and Rhcg expressions were much higher in the soleus (Sol) than in the plantaris (Pla) or gastrocnemius (Gas). Immunofluorescence microscopy demonstrated that Rhbg colocaliz...

Objective: Oxidative stress plays a key role in the pathogenesis of type 2 diabetes mellitus (T2DM) and its complications. Exercise and anti-oxidant supplements are two potential approaches to delay the development of T2DM. The purpose of this study was to evaluate the interaction effects of spirulina supplementation and high intensity interval training (HIIT) on oxidative stress and total anti...

Objective: Hepatic glucose release plays a potential role in hyperglycemia in type 2 diabetes (T2D) patients. The aim of this experimental study was to determine the effect of 6 weeks of high-intensity interval training (HIIT) on fasting levels of glucose and insulin as well as glucokinase (GCK) expression in liver tissue in obese T2D rats. Materials and Methods: T2D was induced by a high-fat ...
