Abstract:

Nine subjects seven experimentals, two controls were studied in order to measure physical performance before, during and after an experimentally induced episode of sandfly fever. During the fever, experimental subjects displayed decreases in measures of isometric muscle strength and isokinetic knee extensor strength at 36second. Three out of the seven subjects were unable to complete a submaximal exercise walk during the fever. Rectal temperature was elevated throughout the walk, but no other physiological parameter was significantly altered. After fever, submaximal exercise performance and muscle strength were similar to the prefever values. Our results indicate that a mild viral infection will diminish isometric strength during fever, as well as cause a marked effect upon the ability andor willingness of some individuals to perform exercise at gradually increasing intensity.
