36 rats were used to determine the effects of: (a) footshock before specific training, (b) CS duration (6 vs 60 sec.), and (c) form of aversive conditioning (CER vs CAR) on heart rate both during the presentation of the CS and between presentations. All three tested variables were effective in modifying the heart-rate response to the CS while only CS duration altered heart rates between CS presentations.

The heart rate response to running various distances was studied using five highly trained girls as subjects. A telemetering instrument was employed so that the testing could be done under actual sport conditions. The findings indicated that 1) the anticipatory heart rate just prior to exercise represented 59% of the total adjustment to exercise, 2) the heart rates during exercise were 2.5 times the resting values, and 3) heart rates observed at the end of the 220-, 440-, 880-yard, and mile events were simila cardiac function; exercise Submitted on October 22, 1963

Heart rates of 30 male Ss were monitored prior to, during, and in recovery from a standard treadmill walk. 10 Ss were trained distance runners and were considered trained in the specific work studied. 10 Ss were conditioned swimmers but were doing a type of work for which they were not trained. The runners had significantly better mean endurance times (time to heart rates 110, 130, 150, and 170) than the swimmers, even though both had previously undergone extensive endurance training. The swimmers did not perform significantly better than a group of nontrained Ss except to heart rate 130. In recovery to heart rate 130, there was no significant difference among the means of the three groups. The only significant difference among group means to final recovery heart rate was between the runners and the nontrained group.

Heart Rates

Weekly measurements of heart rate responses of a hand-reared white-tailed deer fawn to recorded wolf howls were completed through the age of 87 days, with occasional measurements of the responses of three other fawns. Alarm bradycardia was a very predictable initial response to the first howl through 45 days of age. Increased heart rates were observed in response to a chorus of howls 35 s into the 62-s sequence. A most interesting characteristic of the response was a highly significant (sign test) relationship between the direction of the heart rate response at 1-s intervals from one test to another, and from one week to the next, until the fawn was 45 days old. Heart rates varied from 86 to 225 beats per minute during the tests, within the ranges observed for transient stimuli such as horses, rain, machines, and other deer. The fawn remained bedded during the tests. A hiding response and alarm bradycardia in the first few weeks of life seems to be good adaptive strategy as the neonate has little chance to escape from a predator by running.

degli Uberti EC, Ambrosio MR, Bondanelli M, Trasforini G, Valentini A, Rossi R, Margutti A, Campo M. Effect of human galanin on the response of circulating catecholamines to hypoglycemia in man. Eur J Endocrinol 1995;133:723–8. ISSN 0804–4643 Human galanin (hGAL) is a neuropeptide with 30 amino acid residues that has been found in the peripheral and central nervous system, where it often co-exists with catecholamines. In order to clarify the possible role of hGAL in the regulation of sympathoadrenomedullary function, the effect of a 60 min infusion of hGAL (80 pmol·kg−1 · min−1) on plasma epinephrine and norepinephrine responses to insulin-induced hypoglycemia in nine healthy subjects was investigated. Human GAL administration significantly reduced both the release of basal norepinephrine and the response to insulin-induced hypoglycemia, whereas it attenuated the epinephrine response by 26%, with the hGAL-induced decrease in epinephrine release failing to achieve statistical significance. Human GAL significantly increased the heart rate in resting conditions and clearly exaggerated the heart rate response to insulin-induced hypoglycemia, whereas it had no effect on the blood pressure. We conclude that GAL receptor stimulation exerts an inhibitory effect on basal and insulin-induced hypoglycemia-stimulated release of norepinephrine. These findings provide further evidence that GAL may modulate sympathetic nerve activity in man but that it does not play an important role in the regulation of adrenal medullary function.
