The effects of high-intensity progressive resistance training (HIPRT) on cardiovascular function and autonomic neural regulation in older adults are unclear. To investigate this issue, 25 older adults were randomly divided into two groups: control (CON, N = 13, 63 ± 4 years; no training) and HIPRT (N = 12, 64 ± 4 years; 2 sessions/week, 7 exercises, 2–4 sets, 10–4 RM). Before and after four months, maximal strength, quadriceps cross-sectional area (QCSA), clinic and ambulatory blood pressures (BP), systemic hemodynamics, and cardiovascular autonomic modulation were measured. Maximal strength and QCSA increased in the HIPRT group and did not change in the CON group. Clinic and ambulatory BP, cardiac output, systemic vascular resistance, stroke volume, heart rate, and cardiac sympathovagal balance did not change in the HIPRT group or the CON group. In conclusion, HIPRT was effective at increasing muscle mass and strength without promoting changes in cardiovascular function or autonomic neural regulation.
高强度渐进性抗阻训练（HIPRT）对老年人心血管功能和自主神经调节的影响尚不清楚。为了研究这个问题，25名老年人被随机分为两组：对照组（CON，N = 13，63±4岁；不进行训练）和HIPRT组（N = 12，64±4岁；每周2次训练，7项练习，2 - 4组，10 - 4次重复最大量）。在四个月前后，测量了最大力量、股四头肌横截面积（QCSA）、诊室和动态血压（BP）、全身血流动力学以及心血管自主调节功能。HIPRT组的最大力量和QCSA增加，而CON组没有变化。HIPRT组和CON组的诊室和动态血压、心输出量、全身血管阻力、每搏输出量、心率以及心脏交感迷走神经平衡均未改变。总之，HIPRT能有效增加肌肉质量和力量，而不会促进心血管功能或自主神经调节的改变。
