American College of Sports Medicine position stand. Exercise and physical activity for older adults.
- W. Chodzko-Zajko, D. Proctor, +4 authors J. Skinner
- MedicineMedicine and science in sports and exercise

The evidence reviewed in this Position Stand is generally consistent with prior American College of Sports Medicine statements on the types and amounts of physical activity recommended for older adults as well as the recently published 2008 Physical Activity Guidelines for Americans.
Nitric oxide and neurally mediated regulation of skin blood flow during local heating.
There are at least two independent mechanisms contributing to the rise in SkBF during nonpainful local heating: a fast-responding vasodilator system mediated by the axon reflexes and a more slowly responding vasodILator system that relies on local production of NO.
Methodological issues in the assessment of skin microvascular endothelial function in humans.

Postocclusive hyperemia, thermal hyperemias and acetylcholine iontophoresis provide integrated indexes of microvascular function rather than specific endothelial markers, but they are valuable tools and can be used as surrogate endpoints in clinical trials in which the assessment of microVascular function in humans is required.
Heat acclimation improves exercise performance.

It is demonstrated that heat acclimation improves aerobic exercise performance in temperate-cool conditions and provides the scientific basis for employing heat acclamation to augment physical training programs.
Influence of the menstrual cycle on sympathetic activity, baroreflex sensitivity, and vascular transduction in young women.
The present study suggests that the hormonal fluctuations that occur during the normal menstrual cycle may alter sympathetic outflow but not the transduction of sympathetic activity into vascular resistance.
Cutaneous vasodilator and vasoconstrictor mechanisms in temperature regulation.
Factors that can modulate control mechanisms of the cutaneous vasculature, such as gender, aging, and clinical conditions, are discussed, as are nonthermoregulatory reflex modifiers of thermoregulation cutaneous vascular responses.
Measurement of limb venous compliance in humans: technical considerations and physiological findings.
It is demonstrated that venous pressure-volume curves can be generated both rapidly and noninvasively with this technique, and that although whole-limb venous compliance is under negligible sympathetic control in humans, unstressed volume can be affected by the sympathetic nervous system.
Impact of Shear Rate Modulation on Vascular Function in Humans
Differences in the magnitude of antegrade shear rate transduce differences in endothelial vasodilator function in humans, a finding that may have relevance for the impact of different exercise interventions on vascular adaptation in humans.
Age alters the cardiovascular response to direct passive heating.

The older men had a significantly lower increase in total blood flow directed to the skin and redistributed less blood flow from the combined splanchnic and renal circulations at the limit of thermal tolerance.
Prostanoids contribute to cutaneous active vasodilation in humans.

The data suggest that prostanoids contribute to active vasodilation, but do not play a role during local thermal hyperemia.
