Six adolescents with persistent essential hypertension were examined to determine the effect of weight training on their blood pressure and hemodynamics. Five had first completed an endurance training program; one subject trained only by weight lifting. All subjects were reevaluated after 5 +/- 2 months of weight training, and 12 +/- 2 months after cessation of training. Endurance training resulted in an increase in VO2max and decreases in systolic and diastolic blood pressure. After weight training, VO2max had decreased to the level found prior to endurance training, and body weight was significantly increased. Systolic blood pressure after weight training was 17 +/- 4 mm Hg lower than when measured initially (P less than 0.01). Weight training maintained the reduction in diastolic pressure elicited by endurance exercise in those who initially had diastolic hypertension. Cessation of all forms of training resulted in no change in body weight, body fat, or VO2max from the values measured after weight training. Systolic pressure increased significantly with the cessation of training to a value not different from that measured initially. Diastolic pressure also increased after cessation of training, but was still below the initial value. The only significant hemodynamic change found was a reduction in systemic vascular resistance in response to weight training. Weight training in hypertensive adolescents appears to maintain the reductions in blood pressure achieved by endurance training, and may even elicit further reductions in blood pressure.
对六名患有持续性原发性高血压的青少年进行了检查，以确定力量训练对他们血压和血液动力学的影响。其中五人首先完成了耐力训练计划；一名受试者仅通过举重进行训练。所有受试者在力量训练5±2个月后以及训练停止后12±2个月进行了重新评估。耐力训练导致最大摄氧量增加，收缩压和舒张压降低。力量训练后，最大摄氧量降至耐力训练前的水平，体重显著增加。力量训练后的收缩压比最初测量时低17±4毫米汞柱（P<0.01）。力量训练使最初患有舒张期高血压的患者在耐力运动后舒张压的降低得以维持。停止所有形式的训练后，体重、体脂或最大摄氧量与力量训练后测量的值相比没有变化。随着训练停止，收缩压显著升高至与最初测量值无差异的水平。训练停止后舒张压也升高，但仍低于初始值。发现的唯一显著血液动力学变化是力量训练后全身血管阻力降低。高血压青少年进行力量训练似乎能维持耐力训练所实现的血压降低，甚至可能进一步降低血压。
