Differential utilisation of subcellular skeletal muscle glycogen pools: A comparative analysis between 1 and 15 minutes of maximal exercise

C. T. Schytz, N. Ortenblad, K. D. Gejl, J. Nielsen

This study compares glycogen pool utilisation during 1- and 15-minute maximal exercises and examines the effects of low carbohydrate intake on glycogen storage and usage.

Increased mitochondrial surface area and cristae density in the skeletal muscle of strength athletes

J. Botella, C. T. Schytz, T. F. Pehrson, R. Hokken, S. Laugesen, P. Aagaard, C. Suetta, B. Christensen, N. Ortenblad, J. Nielsen

This study examines mitochondrial structural changes in strength athletes compared to untrained controls, finding increased cristae density and surface-to-volume ratio, along with transcriptomic evidence of mitochondrial biogenesis and stress responses.

Specific ATPases drive compartmentalized glycogen utilization in rat skeletal muscle

J. Nielsen, P. Dubillot, M.-L. H. Stausholm, N. Ortenblad

The paper shows that three ATPases in rat skeletal muscle use distinct glycogen pools, revealing compartmentalized glycogen metabolism.

Pharmacological but not physiological GDF15 suppresses feeding and the motivation to exercise

A. B. Klein, T. S. Nicolaisen, N. Ortenblad, K. D. Gejl, R. Jensen, A. M. Fritzen, E. L. Larsen, K. Karstoft, H. E. Poulsen, T. Morville, R. E. Sahl, J. W. Helge, J. Lund, S. Falk, M. Lyngbaek, , C. Clemmensen

The paper shows that exercise increases circulating GDF15 levels, but this physiological increase does not suppress appetite or exercise motivation like pharmacological GDF15.

Fundamental Constraints In Synchronous Muscle Limit Superfast Motor Control In Vertebrates

A. F. Mead, N. Osinalde, N. Ortenblad, J. Nielsen, J. Brewer, M. Vellema, I. Adam, C. Scharff, Y. Song, U. Frandsen, B. Blagoev, I. Kratchmarova, C. P. H. Elemans

The paper identifies evolutionary and functional differences in superfast muscles across vertebrates, showing they evolved independently and are constrained by fundamental limits in synchronous muscle.
