BACKGROUND Moderate sleep complaints are major gerontological issue affecting as many as 80% of older adults. More intriguing findings have indicated that moderate sleep complaints were associated with cognitive decline, functional deterioration, clinical depression, and even morbidity and mortality among older adults. The aim of this study is to evaluate the effects of an activity-based lifest...

It is unclear whether pulmonary oxygen uptake (Vo2) kinetics demonstrate linear, first-order behavior during supra gas exchange threshold exercise. Resolution of this issue is pertinent to the elucidation of the factors regulating oxygen uptake (Vo2) kinetics, with oxygen availability and utilization proposed as putative mediators. To reexamine this issue with the advantage of a relatively larg...

[Abstract] Purpose: The purpose of this study was to investigate the kinetics of cerebral blood flow (CBF) in conjunction with cardiopulmonary response during constant-work rate cycling exercise of moderate and heavy intensities. Methods: Seven subjects (6 males and 1 female; age, 25.4 ± 7.7 yr; height, 171.9 ± 4.3 cm; body mass, 67.7 ± 11.4 kg) participated in the present study. The subjects c...

BACKGROUND Aerobic exercise appears to have clinical benefits for many asthmatics, yet a complete understanding of the mechanisms underlying these benefits has not been elucidated at this time. PURPOSE The objective of this study was to determine feasibility for a larger, future study that will define the effect of aerobic exercise on cellular, molecular, and functional measures in adults wit...
