The distribution of cardiac output was analyzed in six dogs, with the animals at rest and running on a level treadmill for 3 min at 3-4 mph (mild exercise) and 3 min at 6-8 mph (moderate exercise). Organ flows were measured using 25-mug-diam radioactive microspheres. Cardiac output averaged 2.5, 4.6, and 5.7 liters/min, for rest, mild exercise, and moderate exercise, respectively. The greatest ...

CONTEXT A higher duration and intensity of exercise may improve long-term weight loss. OBJECTIVE To compare the effects of different durations and intensities of exercise on 12-month weight loss and cardiorespiratory fitness. DESIGN, SETTING, AND PARTICIPANTS Randomized trial conducted from January 2000 through December 2001 involving 201 sedentary women (mean [SD] age, 37.0 [5.7] years; me...

OBJECTIVES The aim of this study was to evaluate plasma levels of nitric oxide (NO) and certain acute phase proteins (caeruloplasmin, transferrin, haptoglobin, C-reactive protein) in Nigerian subjects after short and prolonged exercises. MATERIALS AND METHODS A total of 57 subjects (34 males and 23 females) between ages of 19 and 45 years participated in this study and were divided into three...

Prior exercise has the potential to enhance subsequent performance by accelerating the oxygen uptake (VO2) kinetics. The present study investigated the effects of two different intensities of prior exercise on pulmonary VO2 kinetics and exercise time during subsequent exhaustive rowing exercise. It was hypothesized that in prior heavy, but not prior moderate exercise condition, overall VO2 kine...

Lifestyle, unhealthy eating patterns, and low physical activity become trigger factors of obesity. Therefore, lifestyle modification with an exercise-based nonpharmacological approach is one the strategies for combat This study aims to analyse response moderate-intensity interval continuous exercise irisin level increasing pattern on obese female. A total 21 females were enrolled in this given ...

Both moderate exercise and the soluble oat fiber beta-glucan can increase immune function and decrease risk of infection, but no information exists on their possible combined effects. This study tested the effects of moderate exercise and oat beta-glucan on respiratory infection, macrophage antiviral resistance, and natural killer (NK) cell cytotoxicity. Mice were assigned to four groups: exerc...

We hypothesized that forearm blood flow (FBF) during moderate intensity dynamic exercise would meet the demands of the exercise and that postexercise FBF would quickly recover. In contrast, during heavy exercise, FBF would be inadequate causing a marked postexercise hyperemia and sustained increase in muscle oxygen uptake (VO(2musc)). Six subjects did forearm exercise (1-s contraction/relaxatio...

AIMS To validate strategies to prevent exercise-induced hypoglycaemia via insulin-dose adjustment in adult patients with type 1 diabetes (T1D) on pump therapy. METHODS A total of 20 patients randomly performed four 30-min late post-lunch (3 h after lunch) exercise sessions and a rest session: two moderate sessions [50% maximum oxygen consumption (VO2 max)] with 50 or 80% basal rate (BR) reduc...
