The purpose of this study was to investigate the effects of short-term creatine intake on muscle fatigue induced by resistance exercise in healthy adolescent men, i.e., lactic acid concentration and wrist and head tremor measured by an accelerometer.Twelve High interstitial K(+) concentration ([K(+)]) has been reported to impede normal propagation of electrical impulses along the muscle cell membrane (sarcolemma) and then also into the transverse tubule system; this is one considered underlying mechanism associated with the development of muscle
The unique lactic acid bacteria, Lactococcus lactis strain plasma (LC-Plasma), stimulates plasmacytoid dendritic cells, which play an important role in viral infection. The authors previously reported that LC-Plasma reduced the number of days athletes experienced cold-like symptoms and
Disturbances in intestinal microbial ecology and in the immune system of the host have been implicated as a part of the pathogenesis in chronic fatigue syndrome. Probiotic lactic acid producing bacteria have been shown to prevent and alleviate gastrointestinal disturbances and to normalize the
OBJECTIVE
This study sought to determine the effects of trunk-muscle fatigue and blood lactic acid elevation on static and dynamic balance.
METHODS
Fatigue was induced by an isokinetic protocol, and static and dynamic balance were assessed during bilateral stance using a Kinesthetic Ability Trainer.
Exercise-induced fatigue is accumulated when lactic acid cannot be timely eliminated after intensive exercise, resulting in sport injuries. Traditional lactic acid removal methods are limited in timeliness, metabolic burden, and potential toxicity. To solve the thorny problems, in this study,
Fatigue produced a marked increase in the lactic acid content of hind-limb muscles, the blood, and the whole animal. After 15 min of rest there was little decline of lactic acid levels but the animals could be stimulated into about 3 min of intense activity. This re-fatigue produced a further
The oral cavity frequently undergoes localized changes in chemistry and level of acidity, which threatens the integrity of the restorative material and supporting hard tissue. The focus of this study was to evaluate the changes in fatigue crack growth resistance of dentin and toughening mechanisms
This study is a job rotation comparative that aims to define the properly scheme to be in use at the time it is performed. As fatigue plays directly against the work results this comprehensive study about the action of lactic acid over workers at different jobs and strength demand was realized to
Composite restorations accumulate more biofilm than other dental materials. This increases the likelihood for the hard tissues supporting a restoration (i.e. dentin and enamel) to be exposed to acidic conditions beyond that resulting from dietary variations. In this investigation the fatigue
Lactic acid is formed and accumulated in the muscle under conditions of high energy demand, rapid fluctuations of the energy requirement and insufficient supply of O2. During intense exercise sustained to fatigue muscle pH decreases to about 6.4-6.6. Force generation does not appear to be limited by
Patients with chronic fatigue syndrome (CFS) are affected by symptoms of cognitive dysfunction and neurological impairment, the cause of which has yet to be elucidated. However, these symptoms are strikingly similar to those of patients presented with D-lactic acidosis. A significant increase of
Postdialysis fatigue (PDF) is not an unusual symptom among hemodialysis (HD) patients; however, its causes remain unclear. The aim of this study was to analyze the factors responsible for PDF in maintenance HD patients.This was a single-center We already showed that group IV muscle afferents are activated during electrically-induced fatigue. The purpose of this study is to identify the mechanisms of stimulation of these muscle afferents by electrically-induced fatigue at a high (100 Hz; high frequency fatigue, HFF) or a low rate (10 Hz;
Intracellular acidosis due mainly to lactic acid accumulation has been regarded as the most important cause of skeletal muscle fatigue. Recent studies on mammalian muscle, however, show little direct effect of acidosis on muscle function at physiological temperatures. Instead, inorganic phosphate,
