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...

H igh-intensity aerobic interval training (HIIT) is a popular strategy for improving cardiorespiratory fitness and health, as well as reducing body fat levels. A standard HIIT protocol involves alternating bouts of both highand low-intensity exercise to increase the amount of high-intensity work performed during an acute bout of training. High-intensity intervals are typically performed above t...

OBJECTIVES To analyze the effects of a long-term intensive lifestyle intervention including high-intensity interval training (HIIT) and Mediterranean diet (MedD) counseling on glycemic control parameters, insulin resistance and β-cell function in obese subjects. METHODS The glycemic control parameters (fasting plasma glucose, glycated hemoglobin), insulin resistance, and β-cell function of 72...

the aim of this study was to assess the effect of four weeks of high intensity aerobic interval football training on aerobic performance indices in soccer players. 18 soccer players in iran azadegan league (age 21.88+2.24 yr, height 174.22+5.33 cm, weight 67.7+5.7 kg, body fat percent 12.38+3.29) volunteered to participate in this study and divided into two groups (training, 12 players; control...
