Skeletal muscleis a remarkable, highly organized tissue which regulates metabolic processes, is important in thermoregulation and serving ultimately as a “molecular motor”. Muscles produce tension, and through tendons move bones to produce meaningful movement and locomotion. With natural human adult agin...
Connective tissue is seen to play a dominant role in the sensation of toughness in muscles where its content is high. In muscles that are generally used for table beef, the contribution of connective tissue is less significant. In either case its contribution to measurable toughness cannot be ...
biology to minimize the effect of Space missions on their health and performance64. The usage of extrinsic or intrinsic factors may allow to re-establish a robust circadian profile for improved adaptation to microgravity, health and performance on orbit. This can be applicable to, for example, in...
To compare the process of muscle aging between species, we generated a mouse muscle aging atlas by sequencing 68,956 cells and 27,573 nuclei from hindlimb muscles of five young (3 months) and three aged (19 months) mice (Fig.1aand Extended Data Fig.2d–g). This atlas yielded the ...
Why do our muscles become tired? Nutrients and oxygen used up very quickly to make energy, muscles begin making energy without oxygen (anaerobically) which creates a buildup of metabolic waste Why do our muscles slow down when they are cold? The enzymes (which make energy by breaking down nu...

(f)CSA in paralyzed muscles 3–6 months post-injury [2]. Changes in the molecular signaling cascades that regulate muscle size are distinct after severe SCI, with muscle loss being more rapid than in other disuse conditions, such ashindlimbimmobilization [3] or sciatic transection [4]. ...
The up-regulation of Igfn1 (1.63-fold) down-regulated protein synthesis by binding to the translation elongation factor eEF1A, and furthermore induced down-regulation of muscle protein biosynthesis in the 24-month-old muscle. Ky is specifically expressed in skeletal and cardiac muscles, and thus...

In the MyoGlu study the dysglycemic men had lower GIR and VO2max than the control men, but higher body weight, body volume, BMI, plasma glucose and insulin levels, leg press strength and larger thigh muscles as compared to control men at baseline (Table 1). Skeletal muscle levels of PC...
