... of people who may be at risk of exercise-related injuries, for example, falls. Whole-body vibration (WBV) is an intervention that helps improve musculoskeletal function and is viable for those with limited mobility. Objectives: Whether WBV has a dual effect on bone and muscle conditions remains unknown. We...

...Jacopo Antonino Vitale; Carmelo Messina; Domenico Albano; Edoardo Fascio; Fabio Galbusera; Sabrina Corbetta; Luca Maria Sconfienza; Giuseppe Banfi Background: The association between the quantity and composition of skeletal muscle and the decline in physical function in elderly is poorly understood...

...Marco Hagen; Sebastian Seidel; Daniel Sanchez Bergmann; Thomas Muehlbauer Background: Associations between lower limb muscle strength and balance performance in adults have previously been reported. However, the function of the foot muscles for postural control has not been understood, yet...

...Sophie Joanisse; Joshua P. Nederveen; Tim Snijders; Bryon R. McKay; Gianni Parise Sarcopenia is the age-related loss of skeletal muscle mass and strength. Ultimately, sarcopenia results in the loss of independence, which imposes a large financial burden on healthcare systems worldwide. A critical...

...Li Li Ji; Chounghun Kang Sarcopenia is age-associated deterioration of muscle mass and function caused by a wide scope of physiological and pathological changes ranging from hormonal disorders to loss of subcellular homeostasis. Recent research indicates that mitochondrial dysregulation...

... to nutritional risk factors and the subtype of sarcopenic obesity. Objective: The aim of this study was to characterize diet-induced and age-related changes on the quality and quantity of the quadriceps muscle in a rat model of sarcopenia by different magnetic resonance (MR) techniques. Methods: A total of 36 6...

...Martin Burtscher Cardiorespiratory fitness (aerobic exercise capacity) is one of the most important prerequisites for successful aging in human beings and depends on adequate oxygen transport by the respiratory and circulatory systems from environmental air to the working muscles and the efficient...

...Emanuele Marzetti; Riccardo Calvani; Roberto Bernabei; Christiaan Leeuwenburgh Background: Sarcopenia, the age-related loss of muscle mass and function, represents a relevant public health issue due to its high prevalence and detrimental consequences. While the exact mechanisms underlying...

...R.D. Jolly; B.V. Douglas; P.M. Davey; J.E. Roiri Pigment of brown atrophy of bovine muscle was interpreted as an exacerbation of age pigment accumulation that also occurred in brain. Isolated muscle pigment was able to be solubilised in LDS/β-mercaptoethanol and found to be composed mainly...

...E. Steinhagen-Thiessen; Abraham Z. Reznick Creatine phosphokinase (CPK) has been shown to provide the initial ATP for muscle contraction. The effect of wheel running on CPK levels was compared in hindleg and cardiac muscles of young, intermediate-age and old outbred CW-1 and inbred C57BL mice...

... for 30 min produced a 3.4°C rise in muscle temperature (Tm) and was associated with a significant (p < 0.001) reduction in maximal time to peak tension and half relaxation time of the twitch, but was without affect on maximal twitch, tetanic (20 and 50 Hz) and voluntary tensions. However, at 10 Hz...

...D.J. Taylor; M. Crowe; P.J. Bore; P. Styles; D.L. Arnold; G.K. Radda Human skeletal muscle has been studied in vivo by 31 P nuclear magnetic resonance. Young adult subjects were compared with healthy elderly subjects aged 70–80 years. Intracellular pH and concentrations of adenosine triphosphate...

...M.J.N. McDonagh; M.J. White; C.T.M. Davies The effect of ageing on voluntary and electrically evoked muscle force was investigated. A group of 70-year-old men and a control group of young men took part in the study. The muscles studied were the elbow flexor group and the triceps surae group...

...R.S. Sohal Age-associated changes in the flight muscles of higher insects, using male housefly as an example, have been discussed. The duration of sustained flight activity declines with age. During the first trimester of adult life, the mitochondrial volume in the flight muscles increases...

...Dennis R. Taaffe; Tim R. Henwood; Michael A. Nalls; Duncan G. Walker; Thomas F. Lang; Tamara B. Harris Background: Aging skeletal muscle is characterized not only by a reduction in size (sarcopenia) and strength but also by an increase in fatty infiltration (myosteatosis). An effective...

..., cigarette smoking, alcohol consumption, physical activity level and psychosocial well-being scores were recorded. Physical performance measured included grip strength, timed chair-stands, stride length and a timed 6-meter walk. Muscle mass was measured using dual-energy X-ray absorptiometry. Relationships...
