This study is to observe the changes of blood pressure (BP), heart rate (HR), double product (DP) and heart rate variability during sexual activity in healthy adults before we cover patients with chronic cardiovascular disease.
Forty-nine participants grouped by sex, 22 males, aged 40.6+/-7.8 years; 27 females, aged 40.3+/-7.8 years, underwent simultaneous ambulatory monitoring of BP and HR for 24 h. During the monitoring period, sexual activity of the participants with man-on-top in their familiar environment was performed. Participants were requested to measure BP manually at the beginning of each sexual phase and three times after orgasm in every 10-min interval and 60 min after orgasm. For each individual, eight measuring values, respectively, about BP, HR, DP and heart rate variability were obtained from baseline to 1 h after orgasm. The data were statistically analyzed with paired t-test and the significant level was set at P<0.05.
In both groups, the peak BP did not appear at orgasm, but at the beginning of plateau and dropped to baseline level at 10 min after orgasm (male 141.41+/-17.13/91.05+/-13.69 vs. 120.14+/-11.07/72.86+/-7.78 mmHg, female 121.67+/-16.61/77.37+/-15.03 vs. 109.37+/-10.54/67.19+/-9.41 mmHg). The peak HR occurred at the beginning of orgasm, and dropped to baseline level 10-20 min after orgasm (male 96.36+/-11.96 vs. 75.41+/-9.02 bpm, female 90.19+/-10.38 vs. 71.44+/-5.68 bpm). DP of both groups elevated at the beginning of plateau and orgasm then decreased to baseline level 10 min after orgasm (male 12964.27+/-2659.17 vs. 9134.09+/-1469.58 mmHg bpm, female 10044.48+/-1777.89 vs. 7841.30+/-1023.79 mmHg bpm). All the results showed that BP, HR and DP have mild to moderate changes during sexual activity in healthy adults.
Using ambulatory technology to monitor BP and HR helps us to get the real data in participants during sexual activity. BP, HR and DP increase just slightly for a short time and recover to baseline level soon after sexual activity in healthy adults. The physical exhaustion during sexual activity is within the range of the daily-life workload.
本研究旨在观察健康成年人在性行为过程中血压（BP）、心率（HR）、双乘积（DP）和心率变异性的变化，随后再纳入慢性心血管疾病患者。
49名参与者按性别分组，男性22名，年龄40.6±7.8岁；女性27名，年龄40.3±7.8岁，进行24小时动态血压和心率监测。在监测期间，参与者在熟悉的环境中进行男上女下式性行为。要求参与者在每个性阶段开始时以及高潮后每隔10分钟测量一次血压，并在高潮后60分钟测量一次。对于每个个体，从基线到高潮后1小时分别获得关于血压、心率、双乘积和心率变异性的8个测量值。数据采用配对t检验进行统计学分析，显著性水平设定为P<0.05。
两组中，血压峰值均未出现在高潮时，而是出现在平台期开始时，并在高潮后10分钟降至基线水平（男性141.41±17.13/91.05±13.69 vs. 120.14±11.07/72.86±7.78 mmHg，女性121.67±16.61/77.37±15.03 vs. 109.37±10.54/67.19±9.41 mmHg）。心率峰值出现在高潮开始时，并在高潮后10 - 20分钟降至基线水平（男性96.36±11.96 vs. 75.41±9.02 bpm，女性90.19±10.38 vs. 71.44±5.68 bpm）。两组的双乘积在平台期开始和高潮时升高，然后在高潮后10分钟降至基线水平（男性12964.27±2659.17 vs. 9134.09±1469.58 mmHg bpm，女性10044.48±1777.89 vs. 7841.30±1023.79 mmHg bpm）。所有结果表明，健康成年人在性行为过程中血压、心率和双乘积有轻度至中度变化。
使用动态监测技术监测血压和心率有助于我们获取参与者在性行为过程中的真实数据。健康成年人在性行为过程中血压、心率和双乘积仅在短时间内略有升高，并在性行为后很快恢复到基线水平。性行为过程中的体力消耗在日常生活工作量范围内。
