The energetic cost of building human skeletal muscle has never been explicitly calculated or measured. We developed a quantitative bottom-up accounting model that integrates human skeletal-muscle comp...

The oxidative stress paradigm stands as a textbook example of how a simplified, early, and appealing scientific concept can become canonized and then resist revision. What began as a plausible heuristic about oxidative stress evolved into a research agenda and a pervasive cultural script.

To store and preserve muscle function, glycerol is often used, but its effect on passive properties is unclear. Muscles stored in glycerol showed increased

Evaluation of the effects of muscle contractions on reactive oxygen species (ROS) concentrations and their intracellular and intraorganelle dynamics i…

In 2005, the Institute of Medicine advised using methods other than nitrogen balance (NB) for determining protein requirements. Since then, protein requirements using indicator amino acid oxidation (I...

Athletic training is characterized by physiological systems responding to repeated exercise-induced stress, resulting in gradual alterations in the functional properties of these systems. The adaptive...

Abstract figure legend Sprint interval training (SIT) is a popular time-efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all-out cycling sprints) over 3...

Molecular oxygen diffuses across membranes with such speed that, despite respiration, the intracellular oxygen concentration does not differ significantly from that outside the cell. In contrast, mem...

The purpose of this project was to provide a profile of DNA, RNA, and protein content in adipose tissue, which is relatively understudied in humans, to gain more insight into the amount of tissue that...

Despite the known metabolic benefits of exercise, an integrated metabolic understanding of exercise is lacking. Here, we use in vivo steady-state isot…

In biology, there are no good or evil molecules. There is limited or no evidence to support the consumption of antioxidants or (super)foods rich in antioxidants, for the intended purpose of an antioxi...

In this Guest editorial for the special issue, Rob Phillips considers some of the ways in which viewing the living through a physical lens allows us to see things that might otherwise remain hidden.
