Macular hemodynamic responses to short-term acute exercise in young healthy adults
We investigated the effects of vigorous exercise on blood flow in the macular vasculature. The velocity and density of entoptically viewed leukocytes in the paramacular retinal capillaries were measured with an Oculix BFS-2000 blue field simulator in 18 healthy adults first at rest, and then after 20 min of exercise. Exercise typically increased the density of leukocytes with more variable effe...
متن کاملKnee loads in the standard and recumbent cycling positions.
The recumbent cycling position (RCP) has become increasingly popular in recent years as a mode of exercise and rehabilitation. However, subtle, but important, differences are expected to exist between the RCP and the standard, upright cycling position (SCP). The differences are due primarily to the altered orientation of the rider's lower extremities relative to gravity. In order to determine i...
متن کاملHemodynamic responses upon the initiation of thermoregulatory behavior in young healthy adults
We tested the hypotheses that thermoregulatory behavior is initiated before changes in blood pressure and that skin blood flow upon the initiation of behavior is reflex mediated. Ten healthy young subjects moved between 40°C and 17°C rooms when they felt 'too warm' (W→C) or 'too cool' (C→W). Blood pressure, cardiac output, skin and rectal temperatures were measured. Changes in skin blood flow b...
متن کاملSomePhysiological Responses to Acute Passive in Healthy Young Adults Smoking
Procedures: Fig. 1. Every subject took parts in 2 successive experiments, that is, a control experiment by sham smoking with non-lit cigarettes and an actua] passive smoking experiment. The habitual smekers took parts in both the experiments as passive smokers and active smokers. All of the subjects participated in the experiments in groups of 2 nonsmokers and 2 smokers. The subjects spent 3 an...
متن کاملForearm vascular responses to mental stress in healthy older adults
Forearm vascular conductance (FVC) increases in response to mental stress (verbal mental arithmetic) in young people. However, the effect of healthy aging and mental stress on FVC is unknown. In this study, we tested the hypothesis that FVC and cutaneous vascular conductance (CVC) would be attenuated in older adults compared to young adults. In 13 young (27 ± 1 year) and 11 older (62 ± 1 year) ...
