The present study deals with the blood pressure (BP) and heart rate (HR) 24-h pattern in aged people of both sexes ranging in age from 66 to 75 years. 20 subjects were active in agonistic sports (running and swimming), 20 others had sedentary habits. BP and HR were studied by non-invasive monitoring along with chronobiometric analysis. The BP and HR 24-h pattern was seen to preserve its circadian rhythm in both aged athletes and sedentary elderly. The analysis reveals that the aged athletes show a higher mesor for systolic BP and a lower mesor for diastolic BP and HR. The daily pressure load, as the integral of the BP 24-h values multiplied by the HR mesor, is lower in aged people practising sport as compared to age-matched individuals with sedentary habits. The spectral analysis reveals that physical exercise acts to change the time structure of BP and HR 24-h patterns. The conclusion is drawn that active sport plays beneficial effects in aged people because of a lower pressure load.
本研究探讨了年龄在66至75岁之间的老年男女的血压（BP）和心率（HR）24小时模式。20名受试者积极参与竞技运动（跑步和游泳），另外20人有久坐习惯。通过无创监测以及时间生物学分析对血压和心率进行了研究。在老年运动员和久坐的老年人中，血压和心率的24小时模式均保持其昼夜节律。分析表明，老年运动员的收缩压中值较高，舒张压和心率的中值较低。与年龄匹配的有久坐习惯的个体相比，从事运动的老年人的每日压力负荷（即24小时血压值乘以心率中值的积分）较低。频谱分析表明，体育锻炼会改变血压和心率24小时模式的时间结构。得出的结论是，由于压力负荷较低，积极运动对老年人有有益影响。
