Increased production of reactive oxygen/nitrogen species (ROS) and impaired cellular Ca(2+) handling are implicated in the prolonged low-frequency force depression (PLFFD) observed in skeletal muscle after both metabolically and mechanically demanding exercise. Metabolically demanding high-intensity exercise can induce PLFFD accompanied by ROS-dependent fragmentation of the sarcoplasmic reticulum Ca(2+) release channels, the ryanodine receptor (RyR)-1. We tested whether similar changes occur after mechanically demanding eccentric contractions...

From the age of fifty onwards a progressive loss of muscle mass may be observed, it often leads to real sarcopenia. Sedentary life style and unbalanced feeding habits represent major risk factors. The decrease in muscle tone leads to a loss of function and an altered quality of life, not to mention socioeconomic factors. The molecular mechanisms of sarcopenia are complex but our understanding of them is increasing. There is no pharmaceutical treatment of sarcopenia of use in current practice. Regular, several times a week, practice of a combination of adapted muscle building physical and endurance exercises, associated with protein intake have shown there use...

Sarcopenia is defined as the progressive loss of muscle mass with age, and poses a serious threat to the physiological and psychological health of the elderly population with consequential economic and social burdens. Chronic low-grade inflammation plays a central role in the development of sarcopenia such that it alters cellular protein metabolism to favor proteolysis over synthesis, and thereby accelerates muscular atrophy. The purpose of this review is to highlight how exercise and nutrition intervention strategies can attenuate or treat sarcopenia...

Aging often results in a decline in cognitive function, related to alterations in the prefrontal cortex (PFC) activation. Maintenance of this function in an aging society is an important issue. Some practices/drills, moderate exercise, mastication, and a cognitive task itself could enhance cognitive function. In this validation study, before evaluating the effects of some drills on the elderly, we examined the neural substrate of blood oxygenation changes by the use of four cognitive tasks and fNIRS. Seven healthy volunteers (mean age 25...

Tryptophan metabolites regulate a variety of physiological processes, and their downstream metabolites enter the kynurenine pathway. Age-related changes of metabolites and activities of associated enzymes in this pathway are suggestable and would be potential intervention targets. Blood levels of serum tryptophan metabolites in C57BL/6 mice of different ages, ranging from 6 weeks to 10 months, were assessed using high-performance liquid chromatography, and the enzyme activities for each metabolic step were estimated using the ratio of appropriate metabolite levels...
