Point:Counterpoint: Skeletal muscle mechanical efficiency does/does not increase with age POINT: SKELETAL MUSCLE MECHANICAL EFFICIENCY DOES INCREASE WITH AGE
We thank Dr. Ortega for the opportunity to debate the concept that aging affects exercise efficiency. From the outset we must acknowledge that, indeed, some studies report an age-related reduction task efficiency during walking and other rather complex tasks (2, 12, 20, 21). However, in contrast, our recent study of leg cycling in centenarians (28), as well as other work focused more specifical...
متن کاملCalcineurin does not mediate exercise-induced increase in muscle GLUT4.
Exercise induces a rapid increase in expression of the GLUT4 isoform of the glucose transporter in skeletal muscle. One of the signals responsible for this adaptation appears to be an increase in cytosolic Ca(2+). Myocyte enhancer factor 2A (MEF2A) is a transcription factor that is involved in the regulation of GLUT4 expression. It has been reported that the Ca(2+)-regulated phosphatase calcine...
متن کاملHypohydration does not impair skeletal muscle glycogen resynthesis after exercise.
The purpose of this investigation was to examine the effects of moderate hypohydration (HY) on skeletal muscle glycogen resynthesis after exhaustive exercise. On two occasions, eight males completed 2 h of intermittent cycle ergometer exercise (4 bouts of 17 min at 60% and 3 min at 80% of maximal O2 consumption/10 min rest) to reduce muscle glycogen concentrations (control values 711 +/- 41 mum...
متن کاملErythropoietin Does Not Enhance Skeletal Muscle Protein Synthesis Following Exercise in Young and Older Adults
PURPOSE Erythropoietin (EPO) is a renal cytokine that is primarily involved in hematopoiesis while also playing a role in non-hematopoietic tissues expressing the EPO-receptor (EPOR). The EPOR is present in human skeletal muscle. In mouse skeletal muscle, EPO stimulation can activate the AKT serine/threonine kinase 1 (AKT) signaling pathway, the main positive regulator of muscle protein synthes...
متن کاملOverexpression of SMPX in Adult Skeletal Muscle Does not Change Skeletal Muscle Fiber Type or Size
Mechanical factors such as stretch are thought to be important in the regulation of muscle phenotype. Small muscle protein X-linked (SMPX) is upregulated by stretch in skeletal muscle and has been suggested to serve both as a transcription factor and a mechanosensor, possibly giving rise to changes in both fiber size and fiber type. We have used in vivo confocal imaging to study the subcellular...
