Near-Infrared Spatially Resolved Spectroscopy as an Indirect Technique to Assess Brown Adipose Tissue in Young Women

Purpose: Near-infrared spectroscopy (NIRS) has recently been proposed as an indirect technique to assess brown adipose tissue (BAT) in young men. NIRS arises as a novel technique to avoid the limitations of the “gold-standard” …

Cerebral hemodynamics and executive function during exercise and recovery in normobaric hypoxia

Hypoxia and exercise each exhibit opposing effects on executive function, and the mechanisms for this are not entirely clear. This study examined the influence of cerebral oxygenation and perfusion on executive function during exercise and recovery …

Limitations of skeletal muscle oxygen delivery and utilization during moderate-intensity exercise in moderately impaired patients with chronic heart failure

The extent and speed of transient skeletal muscle deoxygenation during exercise onset in patients with chronic heart failure (CHF) are related to impairments of local O2 delivery and utilization. This study examined the physiological background of …

Central and peripheral cardiovascular impairments limit VO2peak in Type 1 diabetes

PURPOSE: Cardiovascular risk, predicted by peak O2 uptake (VO2peak), is increased in type 1 diabetes. We examined the contribution of central and peripheral mechanisms to VO2peak in physically active adults with type 1 diabetes. METHODS: Seven men …
