The purpose of this study was to assess the heart rate (HR) and blood pressure (BP) response of sexual activity compared with treadmill exercise in adult men and women. Nineteen men, 55 ± 8 years, and 13 women, 51 ± 7 years, underwent a maximal Bruce protocol treadmill stress test followed by home-monitored sexual activity using noninvasive HR and BP recording devices. The mean treadmill times were significantly shorter than the mean times of sexual activity for men and women (p <0.001 and p = 0.002, respectively). For the men, average maximum HR, systolic BP, and HR–BP product during sexual activity were 72%, 80%, and 57% of respective measurements during treadmill exercise. For the women, maximum HR, systolic BP, and HR–BP product during sexual activity were 64%, 75%, and 48% of respective measurements during treadmill exercise. Age correlated inversely with duration of treadmill exercise (a 9-second decrease in duration per increasing year of age; p = 0.036), and with the duration of sexual activity (a 1-minute decrease in duration per increasing year of age; p = 0.024). Treadmill exercise duration predicted sexual activity duration (a 2.3-minute increase in sexual activity duration per each minute treadmill duration; p = 0.026). In conclusion, sexual activity provides modest physical stress comparable with stage II of the standard multistage Bruce treadmill protocol for men and stage I for women.

Methods

Study participants were solicited from the outpatient cardiology department of the University of Medicine and Dentistry of New Jersey, including staff, patients, and their partners. Sexually active men and women, 40 to 75 years old, were invited to participate. Exclusion criteria were hospitalization in the preceding 3 months, or inability to perform or an ischemic response to treadmill exercise. All participants continued prescribed medications. After signing informed consent, study

Results

Of 39 adults enrolled in the study, 7 were eliminated because of technically inadequate BP recordings during sexual activity. The final study sample was 32, including 19 men (55 ± 8 years), and 13 women (51 ± 7 years) (Table 1). The men had more overt heart disease than the women.

Table 2 lists the hemodynamic characteristics during the participants’ treadmill exercise and sexual activity. Treadmill times were significantly shorter than the duration of sexual activity. The maximum HR, systolic

Discussion

Sexual activity was a modest physical stress comparable to stage II of the standard multistage Bruce treadmill protocol for men and stage I for women. This study confirms and extends previous studies by enrolling a more heterogeneous sample of older men and the largest cohort of women, by using less obtrusive noninvasive HR and BP monitoring devices, and by making direct comparisons between participants’ perceived level of exertion during maximal treadmill exercise and usual sexual activity (

    Sexual activity is an important element of normal human function, well-being, and quality of life.1–3 It is considered a form of physical activity because it requires stretching and physical movement.4,5 Several cohort studies have examined the relationship between sexual activity and mortality risk in the general population, mostly demonstrating an inverse association.6–9

    As early as 1932, Boas and Goldschmidt reported heart rate (HR) changes during coitus by using a rudimentary cardiotachometer,42 which was linked by 100-ft cables to 3 electrodes placed on the participant's chest. Since then, several better controlled studies have subsequently been reported using primarily married couples who engaged in intercourse in their habitual bedroom as participants.14,43-50 These studies considered different types of SA, from self-masturbation to intercourse, as well as distinct male and female body positions during penetration.
