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

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

The maximal lactate steady state (MLSS) is one of the factors that differentiates performance in aerobic events. The purpose of this study was to investigate the sex differences in oxygen consumption (VO2), heart rate (HR), and the respiratory exchange ratio (RER) at the MLSS in well-trained distance runners. Twenty-two (12 female, 10 male) well-trained distance runners (23 ± 5.0 years) performed multiple 30-min steady-state runs to determine their MLSS, during which blood lactate and respiratory gas exchange measures were taken. To interpret the MLSS intensity as a training tool, runners completed a time-to-exhaustion (TTE) run at their MLSS. The relative intensity at which the MLSS occurred was identical between males and females according to both oxygen consumption (83 ± 5 %O2max) and heart rate (89 ± 7 %HRmax). However, female runners displayed a significantly lower RER at MLSS compared to male runners (p < 0.0001; 0.84 ± 0.02 vs. 0.88 ± 0.04, respectively). There was not a significant difference in TTE at MLSS between males (79 ± 17 min) and females (80 ± 25 min). Due to the observed difference in the RER at the MLSS, it is suggested that RER derived estimates of MLSS be sex-specific. While the RER data suggest that the MLSS represents different metabolic intensities for males and females, the relative training load of MLSS appears to be similar in males and female runners.

Response To Exercise

The chapter Heart Rate Response to Exercise reviews the studies performed to estimate a patient’s maximum predicted heart rate. While the commonly used formula (220 – age), developed in 1971, is easy to remember, it underestimates the actual maximum heart rate in older persons. Studies of large sample size have found the maximum heart rate to be relatively independent of sex and physical fitness but to incrementally decline with age. The decrease with age is less than 1 beat per minute per year, however. A more accurate and recommended formula is [(208) – (0.7)(age)] as developed by Tanaka and colleagues.

Neural Influences

Maximum exercise heart rate decreases with maturation in the rat as well as in man. The present study was undertaken to investigate the mechanism(s) which might be responsible for this reduction in max exercise heart rate in the rat. Maximum exercise heart rates were 618 +/- 7 vs. 580 +/- 9 beats/min for the young (5 wk) and mature (19 wk) rats, respectively. Atropine had no effect on max exercise heart rate. Propranolol reduced max heart rate in both groups with the older rats having the lowest value. Resting heart rates were recorded following injections of atropine propranolol, and propranolol plus atropine. Under all conditions, including control, heart rates were lower in the mature rats. Electrical stimulation in situ showed a significant difference in the threshold voltage for stimulation at 600 beats/min: 1.1 +/- 0.2 vs. 1.6 +/- 0.1 V for the young and mature rats, respectively. These data suggest that intrinsic changes occur in the myocardium with maturation and the reduction in max exercise heart rate is due to these intrinsic changes as opposed to changes in neural influences.

Response To Exercise

To study the effects of chronic diabetes on heart rate and adrenergic responsiveness we compared unanesthetized diabetic rabbits, 10-13 mo after alloxan monohydrate injection, to age-matched controls. There were no significant differences found between groups for body or heart weight. Both resting and intrinsic heart rate (the latter obtained after atropine sulfate and propranolol HCl) were similar. In addition, serum and left ventricular epinephrine and norepinephrine concentrations as well as left ventricular beta-receptor density and affinity were unchanged in diabetic animals. Heart rate responses to isoproterenol were blunted in diabetics at the three highest doses. Base-line mean blood pressure was modestly lower in diabetic rabbits, and parallel declines in pressure for both groups were observed in response to isoproterenol. The diminished heart rate response to isoproterenol in diabetic rabbits may be due to diminished myocardial sensitivity to catecholamines, possibly combined with altered baroreceptor reflexes. These experiments may provide an explanation for the blunted heart rate response to exercise described in human diabetics.

This study was used to assess the premise that lower resting heart rates should be associated with higher scores on self-efficacy for exercisers. A total of 64 participants, 29 men and 35 women ranging in age from 18 to 38 years old ( M = 23.22, SD = 4.19), currently participating in an exercise program at a fitness center, were assessed using the Exercise Specific Self-efficacy Scale to measure general individual self-efficacy, along with obtaining resting heart rates. Participants were separated into three different groups based on individual resting heart-rate values. Results for a 2 (sex) by 3 (heart rate) two-way analysis of variance indicated a significant difference in self-efficacy scores ( F2.58 = 3.24, p<.05) among the three groups. No interaction or main effect for sex was found.
