PURPOSE This study examined the effects of age and training status on the pulmonary oxygen uptake (VO2p) kinetics of untrained and chronically trained young, middle-age, and older groups of men. METHODS Breath-by-breath VO2p and near-infrared spectroscopy-derived muscle deoxygenation ([HHb]) were monitored continuously in young (20-39 yr) trained (YT, n = 8) and untrained (YuT, n = 8), middle...
PURPOSE The 1-repetition maximum (1-RM) test is the gold standard test for evaluating maximal dynamic strength of groups of muscles. However, safety of actual 1-RM testing is questionable in clinical situations such as type 2 diabetes (T2D), where an estimated 1-RM test is preferred. It is unclear if acceptable test retest reliability exists for the estimated 1-RM test in middle aged T2D patien...
This study investigated the influence of cueing on the performance of untrained and trained complex motor responses. Healthy adults responded to a visual target by performing four sequential movements (complex response) or a single movement (simple response) of their middle finger. A visual cue preceded the target by an interval of 300, 1000, or 2000 ms. In Experiment 1, the complex and simple ...
OBJECTIVE To investigate the relationships among perceived school experiences, diabetes control, and quality of life (QOL) in children with diabetes. METHODS Fifty-eight children with type 1 diabetes and their parents participated. The typical child was 12 years old, had diabetes for 5 years, and attended public, suburban, middle/junior high schools with 300-500 students. RESULTS Children w...
What perceptual information do artists use to accurately render what they see? To answer this question, we investigated the utility of low, middle, and high spatial frequency bands for drawing. Untrained artists drew portraits from four spatial frequency bands (unfiltered, low, middle, and high). Raters judged the accuracy of those drawings compared to images of either the same or an unfiltered...
Middle cerebral artery mean velocity (MCAvmean) is attenuated with increasing age both at rest and during exercise. The aim of this study was to determine the influence of the age-dependent reduction in arterial Pco2 (PaCO2) and physical fitness herein. We administered supplemental CO2 (CO2 trial) or no additional gas (control trial) to the inspired air in a blinded and randomized manner, and a...
Aerobic exercise positively impacts cardiometabolic risk factors and diseases; however, the most effective exercise training strategies have yet to be identified. To determine the effect of high intensity (interval) training (HI(I)T) versus moderate intensity continuous exercise (MICE) training on cardiometabolic risk factors and cardiorespiratory fitness we conducted a 16-week crossover RCT wi...
This investigation examined the crosstraining effect of swim training on middle distance running performance. Eight, healthy, untrained subjects (mean age + SD = 24.63 + 2.77 yrs) participated in a 12 week. swim training program. Before and immediately following the training period, measurements were made of: maximal oxygen consumption (V03 max.) (treadmill); anaerobic capacity (Wingate test); ...
Background and Objective: The results of researches have shown that heavy and prolonged exercise increases the risk of upper respiratory tract infection in athletics. The aim of this study was to determine the effect of a 6 month aerobic exercise on the levels of serum immunoglobulin in untrained middle-aged women. Materials and Methods: For this study, nineteen healthy female middle-...
