26 The primary objective of this study was to determine whether cardiovascular 27 compensatory response phenotypes exist in the face of a reduced perfusion pressure 28 challenge to exercising muscle oxygen delivery (O2D), and whether these responses might 29 be exercise intensity (EI) dependent. Ten healthy male subjects (19.5±0.4 years) completed 30 two trials of progressive forearm isometric ...

AIMS/INTRODUCTION Low aerobic capacity is a strong and independent predictor of all-cause mortality in patients with metabolic syndrome (MetS). Here, we investigated the effects of pioglitazone treatment on whole-body aerobic capacity and skeletal muscle energy metabolism in MetS patients. MATERIALS AND METHODS A total of 14 male patients with MetS received oral pioglitazone 15 mg/day for 4 m...

Little evidence exists with regard to changes in cardiac strain that occur during submaximal exercise in young males. The aims of the study were to evaluate the changes that occur in longitudinal (L), radial (R), and endocardial circumferential (EC) strain during submaximal upright cycle ergometry and to examine the test-retest reproducibility of these measurements. Fourteen recreationally acti...

the purpose of this study was to examine the effects of omega3 and aerobic exercise intervention on the calcium metabolism regulating hormones in non – athlete postmenopausal women. for this purpose 40 healthy non – athlete postmenopausal women with age 57.72±3.53 years, height 157,75±9,24 cm, weight 58.08±12.76kg, bmi 23.78±3.73kg/m2, fat 23.18±4.68% volunteered in this study. subjects in a do...

BACKGROUND Aerobic endurance is an important aspect of physical fitness that enables individuals living with HIV to endure in the work place as well as in agricultural operations in order to earn a living and improve their quality of life. However, despite high HIV prevalence rates, the aerobic endurance status of young Malawians living with HIV remains unknown. The objective of this study was ...

Fifty-five healthy, sedentary, nonsmoking, and nonobese 24- to 26-year-old men who had low plasma concentrations of high density lipoprotein (HDL) cholesterol were selected for a study of the effect of short-term exercise on plasma lipid and lipoprotein concentrations. The participants were randomized into two groups. Of these, 28 were assigned to a 9-week program of submaximal aerobic exercise...

conclusions it seems that in people with type 2 diabetes, acute aerobic exercise can decrease the plasma levels of glucose, possibly through increasing orexin a. in addition, negative energy balance is necessary to decrease the levels of insulin and insulin resistance during acute aerobic exercise. results the analysis of findings in p ≤ 0.05 indicated that acute aerobic exercise caused a signi...

OBJECTIVE A lower frequency for the peroxisome proliferator-activated receptor γ coactivator 1α (PPARGC1A) Ser482 allele has been reported in elite-level endurance athletes among Caucasians, although this gene polymorphism has not been found to be associated with aerobic capacity in German, Dutch or Chinese populations. The purpose of the current study was to examine the associations between th...

Lungless salamanders (4.1 g) were exercised on a treadmill enclosed in a Plexiglas respirometer at a range of speeds (0.05-0.24 km/h). O2 consumption (VO2) was determined continuously by open-flow respirometry. At the onset of exercise VO2 increased to a "steady state" in approximately 2-5 min. VO2 (ml O2 X g-1 X h-1) increased linearly with speed (S), VO2 = 2.3 (S) + 0.1 (r2 = 0.74). The minim...
