Central fatigue and nycthemeral change of serum tryptophan and serotonin in the athletic horse
BACKGROUND: The serotonergic system is associated with numerous brain functions, including the resetting of the mammalian circadian clock. The synthesis and metabolism of 5-HT in the brain increases in response to exercise and is correlated with high levels of blood-borne tryptophan (TRP). The present investigation was aimed at testing the existence of a daily rhythm of TRP and 5-HT in the bloo...
متن کاملCentral and Peripheral Fatigue During Resistance Exercise – A Critical Review
Resistance exercise is a popular form of conditioning for numerous sport disciplines, and recently different modes of strength training are being evaluated for health benefits. Resistance exercise differs significantly in nature, and several variables determine the direction and range of adaptive changes that occur in the muscular and skeletal system of the body. Some modes of resistance traini...
متن کاملCentral and peripheral fatigue after electrostimulation-induced resistance exercise.
PURPOSE To investigate central and peripheral fatigue induced by a typical session of electromyostimulation (EMS) of the triceps surae muscle. METHODS A series of neuromuscular tests including voluntary and electrically evoked contractions were performed before and immediately after 13 min of EMS (75 Hz) in 10 healthy individuals. RESULTS Maximal voluntary contraction torque of the plantar ...
متن کاملHyperthermia and central fatigue during prolonged exercise in humans.
The present study investigated the effects of hyperthermia on the contributions of central and peripheral factors to the development of neuromuscular fatigue. Fourteen men exercised at 60% maximal oxygen consumption on a cycle ergometer in hot (40 degrees C; hyperthermia) and thermoneutral (18 degrees C; control) environments. In hyperthermia, the core temperature increased throughout the exerc...
متن کاملEffect of the oral administration of tryptophan-free amino acid mixtures on serum tryptophan, brain tryptophan and serotonin metabolism.
TRYPTOPHAN (Try) is the only amino acid circulating in plasma which is bound to serum proteins (MCMENAMY & ONCLEY, 1958). Previous studies from our (TAGLIAMONTE et al., 1971a; GESSA et al., 1972; TAGLIAMONTE et al., 1973a; 1973b) and Curzon's laboratories (KNOTT & CURZON, 1972) have shown that the concentration of free Try in serum parallels in many instances the concentration of Try in brain w...
