2 Exercise and Endogenous Opiates
نویسندگان
چکیده
The discovery of endogenous opiates in 1975 (1) generated considerable research concerning the effects of exercise on the release of these peptides, particularly on -endorphin, which represents the main focus of this chapter. Previous research considered changes in peripheral blood concentrations induced by different modes of physical activity, influences of training status on the secretion of endogenous opiates, and the physiological meaning of the -endorphin release during exercise. Such phenomena as “runner’s high,” “second wind,” or “exercise dependency” were related to endogenous opiate activity. This chapter summarizes what is known about the stimulation of opioid release by physical activity. Physiological mechanisms responsible for the secretion are highlighted, as well as the consequences of opioid activity. Implications for future research, training, and competition are discussed.

متن کاملThe role of endogenous opiates in thermal regulation of the body during exercise.
Naloxone abolished the rise in body temperature seen after bicycle ergometer tests performed by 10 healthy men. This suggests that endogenous opiates play a part in thermal regulation during muscular exercise.
متن کاملENDOGENOUS RELEASE OF OPIATES BY REPETITIVE ELECTRICAL FIELD STIMULATION IN THE GUINEA-PIG AND RAT ILEAL LONGITUDINAL MUSCLE
The effect of repetitive electrical field stimulation and the response of the guinea-pig and rat ileal longitudinal muscle to single pulse stimulations was examined. Single pulse field stimulation produced twitch contraction which was inhibited by repetitive field stimulation (10 Hz, 40V, 0.5 msec for 5 m). This inhibition was largely, though never completely, reversed by naloxone. Contrac...
متن کاملThe role of the endogenous opiates as regulators of appetite 1 ’ 2
The popular view of the major function of the opiates is that they produce analgesia. Much evidence has been accumulated that the endogenous opiates play an integral role in the central regulation of appetite. We postulate that the major effect of the endogenous opiates is to induce the feeding drive with their analgesic properties representing an epiphenomenon. Am J Cli,, Nuir 1982;35:757-76l.
