摘要

运动的急性效应可以阐明运动在几个系统（如大脑、肌肉和骨骼）中益处的分子和心理生理机制。在这项研究中，63名健康的久坐绝经后妇女被随机分为HIIAE组（ = 20）、HIIAE+WBV组（ = 20）和对照组（ = 23），并在全身振动（WBV）平台（HIIAE+WBV）上进行单次30分钟的高强度间歇有氧运动（HIIAE）结合等长阻力运动，比较HIIAE与单独HIIAE对分子和神经认知指标的影响。评估的分子指标为血清骨钙素（OC）、未羧化OC （ucOC）、羧化OC （cOC）、脑源性神经营养因子（BDNF）和鸢尾素水平，评估的神经认知指标为视觉空间工作记忆任务中P2和P3组分的准确率（AR）、反应时间（RT）和脑电图事件相关电位（ERPs）。比较HIIAE或HIIAE+WBV急性发作前后或静息期后这些指标的数据。HIIAE或HIIAE+WBV干预对绝经后妇女的ERP P2潜伏期/振幅和P3潜伏期无显著影响，但可显著提高ARs，缩短RTs，提高ERP P3振幅，提高OC、cOC、BDNF和鸢尾素水平。HIIAE+WBV在AR、ucOC和BDNF中的表现优于HIIAE单独治疗。然而，在本研究中，两种运动模式引起的这些分子和神经认知指标的变化并没有显示出显著的相关性。目前的研究结果表明，HIIAE和HIIAE+WBV有可能对骨骼和大脑健康的标志物产生急性影响，HIIAE+WBV比单独HIIAE更有效。这些干预措施应在未来涉及绝经后妇女的随机对照试验中进一步研究。

Acute effects of high-intensity interval exercise plus whole-body vibration on bone turnover markers, BDNF, irisin, and neurocognitive performance in postmenopausal women

The acute effects of exercise can elucidate the molecular and psychophysiological mechanisms underlying exercise’s benefits in several systems (e.g., the brain, muscle, and bone). In this study, a single 30-minute session of high-intensity interval aerobic exercise (HIIAE) administered in conjunction with isometric resistance exercise on a whole-body vibration (WBV) platform (HIIAE+WBV) was compared with HIIAE alone in their effects on molecular and neurocognitive indices among 63 sedentary, healthy postmenopausal women who were randomly assigned to HIIAE (n = 20), HIIAE+WBV (n = 20), and Control (n = 23) groups. The assessed molecular indices were serum levels of osteocalcin (OC), uncarboxylated OC (ucOC), carboxylated OC (cOC), brain-derived neurotrophic factor (BDNF), and irisin, and the assessed neurocognitive indices were the accuracy rate (AR), reaction time (RT), and electroencephalography event-related potentials (ERPs) of P2 and P3 components in a visuospatial working memory task. Data on these indices before versus after an acute bout of HIIAE or HIIAE+WBV or after a resting session were compared. An HIIAE or HIIAE+WBV intervention yielded no significant change in ERP P2 latency/amplitude and P3 latency but yielded significantly higher ARs, shorter RTs, larger ERP P3 amplitudes, and higher OC, cOC, BDNF, and irisin levels in the postmenopausal women. HIIAE+WBV outperformed HIIAE alone in AR, ucOC, and BDNF. However, the changes in these molecular and neurocognitive indices induced by the two exercise modes did not show any significant correlations in the present study. The present findings suggest that HIIAE and HIIAE+WBV have the potential to acutely influence markers of bone and brain health, with HIIAE+WBV showing greater effectiveness than HIIAE alone. These interventions should be further investigated in future randomized controlled trials involving postmenopausal women.

期刊介绍： Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane. The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
