Mammalian skeletal muscle comprises different fiber types, whose identity is first established
during embryonic development by intrinsic myogenic control mechanisms and is later …

The anaerobic threshold (AT) remains a widely recognized, and contentious, concept in
exercise physiology and medicine. As conceived by Karlman Wasserman, the AT coalesced …

Despite limited scientific evidence supporting their effectiveness, warm-up routines prior to
exercise are a well-accepted practice. The majority of the effects of warm up have been …

Muscular exercise requires transitions to and from metabolic rates often exceeding an order
of magnitude above resting and places prodigious demands on the oxidative machinery 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 …

ABSTRACT JONES, AM, B. GRASSI, PM CHRISTENSEN, P. KRUSTRUP, J. BANGSBO,
and DC POOLE. Slow Component of VO2 Kinetics: Mechanistic Bases and Practical …

In skeletal muscle, carnitine plays an essential role in the translocation of long‐chain fatty‐
acids into the mitochondrial matrix for subsequent β‐oxidation, and in the regulation of the …

Near-infrared spectroscopy (NIRS) was utilized to gain insights into the kinetics of oxidative
metabolism during exercise transitions. Ten untrained young men were tested on a cycle …

The activities of daily living typically occur at metabolic rates below the maximum rate of
aerobic energy production. Such activity is characteristic of the nonsteady state, where …

Chronic heart failure (CHF) impairs critical structural and functional components of the O2
transport pathway resulting in exercise intolerance and, consequently, reduced quality of …
