The aim of this experiment was to determine whether low impact forced exercise improved learning and memory in middle aged and older mice. The effects of 12 weeks of low impact, forced running on motor learning and spatial memory were compared in 32 C57BL/6 mice in three age groups with a mean age of 13, 17, and 25 months. Motor learning was assessed with the rotorod, and spatial memory was ass...

reduction in the forced expiratory volume in one second after exercise was calculated using the pre-exercise value as the baseline value. Statistical significance was calculated with Student's paired t test. The study was approved by the research ethical committee of the Faculty of Medicine, Queen's University, Belfast. The table shows the percentage reduction in forced expiratory volume in one...

The purpose of the study was to investigate the effects of one night's sleep deprivation on the cardiorespiratory responses to exercise during the follicular and luteal phases of the menstrual cycle. We have studied nine, healthy females aged 24-35 years with regular menstrual cycles. Each subject performed spirometric tests at rest and then an incremental exercise testing during 11-13 days of ...

The goal of this study was to determine whether the stress of forced exercise would result in injury to the myocardium. Male rats with 8% of body weight attached to the tail were forced to swim 3.5 h (3.5S), forced to swim 5 h (5S), or pretrained for 8 days and then forced to swim 5 h (T5S). Rats were killed immediately after they swam (0 h PS) and at 3 h (3 h PS), 24 h (24 h PS), and 48 h afte...

We studied whether bronchodilatation occurs with exercise during the late asthmatic reaction (LAR) to allergen (group 1, n = 13) or natural asthma (NA; group 2, n = 8) and whether this is sufficient to preserve maximum ventilation (VE(max)), oxygen consumption (VO(2 max)), and exercise performance (W(max)). In group 1, partial forced expiratory flow at 30% of resting forced vital capacity incre...

Purpose The purpose of this study was to determine the effects of forced inspiration and forced inspiration and forced expiration exercise on stroke patients’ trunk muscle activity, trunk control ability. Methods Twenty four patients with stroke were randomly assigned to a control group with physical therapy and a complex breath exercise as well. The complex breath exercise group received physi...

exercise induced asthma (eia) is a transient increase in airway resistance after intensive exercise and can be measured as a decline in forced expiratory volume in one second (fev1). the condition is due to increased training load and inhalation of cold and dry air. several studies have shown that eucapnic voluntary hyperpnea challenge test (evh test) is a very sensitive and specific diagnostic...

Lipopolysaccharide (LPS) is an endotoxin derived from Gram-negative bacteria, which induces brain inflammation. LPS-induced brain inf lammation deteriorates hippocampus-dependent cognitive deficits. In the present study, we investigated the effects of forced treadmill exercise and voluntary wheel exercise on short-term memory in relation to neuronal maturation in LPS-induced brain inflammation ...
