Near infrared spectroscopy (NIRS) is a powerful noninvasive tool with which to study the
matching of oxygen delivery to oxygen utilization and the number of new publications …

The commercial market for technologies to monitor and improve personal health and sports
performance is ever expanding. A wide range of smart watches, bands, garments, and …

In most daily activities related to work or leisure, the energy for muscle work substantially
comes from oxidative metabolism. Functional limitations or impairments of this metabolism …

Heart failure with preserved ejection fraction (HFpEF) is a complex syndrome with an
increasingly recognized heterogeneity in pathophysiology. Exercise intolerance is the …

Background—Inorganic nitrate (NO3−), abundant in certain vegetables, is converted to
nitrite by bacteria in the oral cavity. Nitrite can be converted to nitric oxide in the setting of …

The final steps of the O2 cascade during exercise depend on the product of the
microvascular‐to‐intramyocyte PO 2 P_O_2 difference and muscle O2 diffusing capacity (D …

Key points In vivo skeletal muscle mitochondrial respiratory capacity was determined from
the post‐exercise recovery kinetics of muscle oxygen consumption () measured using near …

Magnetic resonance spectroscopy (MRS) can give information about cellular metabolism in
vivo which is difficult to obtain in other ways. In skeletal muscle, non‐invasive 31 P MRS …

Near-infrared spectroscopy (NIRS) to monitor muscle oxygen saturation (SmO2) is rapidly
expanding into applied sports settings. However, the technology is limited due to its inability …

In order to identify peripheral biomarkers of impaired oxidative metabolism during exercise
following a 10‐day bed rest, 10 males performed an incremental exercise (to determine …
