A single exercise session evokes immediate blood pressure (BP) reductions that persist for at least 24 h, termed postexercise hypotension (PEH). Self-monitoring of PEH may foster positive outcome expectations of exercise, and thus, enhance exercise adherence among adults with hypertension.
To compare the efficacy of self-monitoring of exercise (EXERCISE) versus exercise and PEH (EXERCISE + PEH) to improve exercise adherence and BP control among adults with hypertension.
Adults with high BP were randomized to EXERCISE (n = 12) or EXERCISE + PEH (n = 12). Participants underwent supervised, moderate intensity aerobic exercise training for 40-50 min/session, 3 days/week for 12 weeks and encouraged to exercise unsupervised at home at least 30 min/day, 1-2 days/week. EXERCISE + PEH also self-monitored BP before and after exercise. Adherence was calculated as [(no. of exercise sessions performed/no. of possible exercise sessions) × 100%]. BP was measured pre and posttraining.
Healthy, middle-aged (52.3 ± 10.8 years) men (n = 11) and women (n = 13) with hypertension (136.2 ± 10.7/85.2 ± 8.9 mmHg) completed exercise training with 87.9 ± 12.1% adherence. EXERCISE + PEH demonstrated greater adherence to supervised training (94.3 ± 6.6%) than EXERCISE (81.6 ± 13.2%; P = 0.007). EXERCISE + PEH performed 32.6 ± 22.5 min/week more unsupervised home exercise than EXERCISE (P = 0.004), resulting in greater exercise adherence (107.3 ± 18.7%) than EXERCISE (82.7 ± 12.2%; P = 0.002). Post versus pretraining BP was reduced -7.4 ± 11.3/-4.9 ± 9.9 mmHg (P < 0.025) with no statistical difference between EXERCISE (-5.2 ± 13.3/-3.6 ± 6.1 mmHg) and EXERCISE + PEH (-9.9 ± 11.3/-6.1 ± 6.9 mmHg; P > 0.344).
The current study is the first to demonstrate that PEH self-monitoring is an efficacious tool to improve exercise adherence among a small sample of adults with hypertension. Future research among a larger, more diverse sample is needed to confirm these novel findings and determine whether EXERCISE + PEH translates to better BP control relative to EXERCISE self-monitoring alone.
单次运动可立即降低血压(BP),且至少持续 24 小时,称为运动后低血压(PEH)。PEH 的自我监测可能会增强对运动的积极预期,从而提高高血压成年人的运动依从性。
比较自我监测运动(EXERCISE)与运动和 PEH(EXERCISE+PEH)改善高血压成年人运动依从性和血压控制的效果。
将高血压成年人随机分为 EXERCISE(n=12)或 EXERCISE+PEH(n=12)组。参与者接受监督的、中等强度的有氧运动训练,每次 40-50 分钟,每周 3 次,持续 12 周,并鼓励他们在家中进行非监督运动,每天至少 30 分钟,每周 1-2 天。EXERCISE+PEH 还在运动前后自我监测血压。依从性计算为[(完成的运动次数/可能的运动次数)×100%]。在训练前后测量血压。
有 11 名健康的中年男性(52.3±10.8 岁)和 13 名女性(n=13)高血压患者(136.2±10.7/85.2±8.9mmHg)完成了 87.9±12.1%的运动训练。EXERCISE+PEH 组的监督训练依从性(94.3±6.6%)高于 EXERCISE 组(81.6±13.2%;P=0.007)。EXERCISE+PEH 组在家中进行的非监督自主运动比 EXERCISE 组多 32.6±22.5 分钟/周(P=0.004),因此运动依从性更高(107.3±18.7%)EXERCISE 组(82.7±12.2%;P=0.002)。与训练前相比,运动后血压降低了-7.4±11.3/-4.9±9.9mmHg(P<0.025),EXERCISE 组(-5.2±13.3/-3.6±6.1mmHg)和 EXERCISE+PEH 组(-9.9±11.3/-6.1±6.9mmHg;P>0.344)之间没有统计学差异。
本研究首次证明,PEH 自我监测是提高高血压成年人运动依从性的有效工具。需要在更大、更多样化的样本中进行进一步的研究,以证实这些新发现,并确定 EXERCISE+PEH 是否比单独进行 EXERCISE 自我监测更能改善血压控制。
