A patient with exercise-induced asthma is described in whom the post-exercise fall in F.E.V.1 was not prevented by the inhalation of isoprenaline immediately before exercise but was almost completely prevented by subcutaneous atropine given 40 minutes before exercise. A large fall in F.E.V.1 similar to the fall after exercise occurred after carbon dioxide-induced hyperventilation and voluntary ...

While a dramatic increase in the number of bromodeoxyuridine (BrdU)-positive cells in the adult dentate gyrus following voluntary exercise has been consistently reported, it has never been determined whether this reflects an increase in neurogenic activity or an exercise-induced increase in the metabolic processing of systemically injected BrdU (a compound that inserts itself into the D N A of ...

background exposure to morphine decreases neurogenesis in the hippocampus. recent studies have shown that voluntary running decreases the severity of anxiety behaviors and cognitive deficits, and increased synaptic plasticity in morphine-dependent rats. objectives this study aimed to investigate whether the morphine dependence-induced attenuation of hippocampal neuron number in rats would be re...

Involuntary physical activity induced by the avoidance of electrical shock leads to improved endurance exercise capacity in animals. However, it remains unknown whether voluntary stand-up physical activity (SPA) without forced simulating factors improves endurance exercise capacity in animals. We examined the eff ects of SPA on body weight, cardiac function, and endurance exercise capacity for ...

PURPOSE Most candidate gene studies on the neurobiology of voluntary exercise behavior have focused on the dopaminergic signaling pathway and its role in the mesolimbic reward system. We hypothesized that dopaminergic candidate genes may influence exercise behavior through additional effects on executive functioning and that these effects are only detected when the types of exercise activity ar...

Obesity during pregnancy contributes to the development of metabolic disorders in offspring. Maternal exercise may limit gestational weight gain and ameliorate these programming effects. We previously showed benefits of post-weaning voluntary exercise in offspring from obese dams. Here we examined whether voluntary exercise during pregnancy influences lipid and glucose homeostasis in muscle and...

AIM To investigate whether there is a sex difference in exercise induced muscle damage. MATERIALS AND METHOD Vastus Lateralis and patella tendon properties were measured in males and females using ultrasonography. During maximal voluntary eccentric knee extensions (12 reps x 6 sets), Vastus Lateralis fascicle lengthening and maximal voluntary eccentric knee extensions torque were recorded eve...

OBJECTIVE(S) The effect of maternal voluntary exercise on hippocampal BDNF level in rat offspring was studied. In addition, the possible role of hippocampal BDNF receptors in maternal exercise induced enhancement of learning in the rat pups was investigated. MATERIALS AND METHODS Pregnant rats have been randomly assigned to sedentary control or voluntary exercise groups. Each of the exercisin...
