Changes in blood pressure and electrocardiogram are important factors that determine exercise testing. This study investigated blood pressure and electrocardiogram (ECG) changes in healthy young adults after performing acute moderate aerobic exercise protocols.
Forty young healthy untrained non-athletes, twenty males and twenty females (age, 25 ± 5.6 years; body weight, 65 ± 4.0 kg; body height, 176.9 ± 2.5 cm) were recruited for the study. The exercise regimen was acute moderate exercise for 20 min on a treadmill consistently for 14 days daily at the speed of 13 km/h. The body weight, blood pressure, and electrocardiograph were measured before and after exercise.
There was a significant reduction (P < 0.05) in body weight (59 ± 3.2 kg) of female participants after 14 days of aerobic exercise relative to their baseline mean value (63 ± 2.9 kg). The systolic blood pressure decreased (P < 0.05) in males (117 ± 1.1 mmHg) and females (117 ± 1.0 mmHg) when compared to the mean baseline values in males (127 ± 1.3 mmHg) and females (128 ±0 .3 mmHg). The diastolic blood pressure also decreased (P < 0.05) in male (71 ± 0.88 mmHg) participants after exercise when compared to the baseline mean values (79 ± 1.2 mmHg) while there was no change in diastolic blood pressure of females. The ECG parameters remained unchanged, while the heart rate (75 ± 1.3 beats/min) increased (P < 0.05) after exercise in all participants relative to the baseline (69 ± 2 beats/min).
The results suggest that moderate aerobic exercise normalized blood pressure and electrical activity of the heart while reducing heart rate after 14 days of consistent aerobic exercise in healthy individuals.
血压和心电图的变化是决定运动测试的重要因素。本研究探讨了健康年轻成年人在进行急性中度有氧运动方案后血压和心电图（ECG）的变化。
本研究招募了 40 名年轻健康的未经训练的非运动员，其中 20 名男性和 20 名女性（年龄 25 ± 5.6 岁；体重 65 ± 4.0 公斤；身高 176.9 ± 2.5 厘米）。运动方案为每天在跑步机上进行 14 天的急性中度运动，速度为 13 公里/小时，持续 20 分钟。在运动前后测量体重、血压和心电图。
与基线平均值（63 ± 2.9 公斤）相比，14 天有氧运动后女性参与者的体重（59 ± 3.2 公斤）显著下降（P < 0.05）。与男性（127 ± 1.3 毫米汞柱）和女性（128 ± 0.3 毫米汞柱）的基线平均值相比，男性（117 ± 1.1 毫米汞柱）和女性（117 ± 1.0 毫米汞柱）的收缩压降低（P < 0.05）。与基线平均值（79 ± 1.2 毫米汞柱）相比，运动后男性（71 ± 0.88 毫米汞柱）的舒张压也降低（P < 0.05），而女性的舒张压没有变化。心电图参数保持不变，而所有参与者的心率（75 ± 1.3 次/分钟）在运动后（相对于基线值 69 ± 2 次/分钟）增加（P < 0.05）。
结果表明，在健康个体中进行 14 天持续的有氧运动后，中度有氧运动可使血压和心脏电活动正常化，同时降低心率。
