Foam rolling (FR) is a self-myofascial release technique with unclear effects on autonomic functioning, indexed by heart rate variability (HRV). FR can be perceived as painful or relaxing, which may explain interindividual HRV responses.
To determine if acute FR alters resting HRV. A secondary aim was to determine if perceived pain during FR would predict HRV responses.
Academic institution.
In a randomized, crossover design, healthy adults (50% female) performed total body FR or control on separate days. Perceived pain ratings were obtained following FR of each muscle group and summed to generate an overall perceived pain rating. Seated measures of the mean RR interval and the natural logarithm of the root-mean square of successive RR interval differences (LnRMSSD, a parasympathetic HRV index) were obtained at 5-10 min pre-, 5-10 min post-, and 25-30 min post-FR.
No effects were observed for RR interval ( = .105-.561) or LnRMSSD ( = .110-.129). All effect sizes ranged from trivial-small (0.00-0.26). Changes in RR interval ( = 0.220-0.228, = .433-.488) and LnRMSSD ( = 0.013-0.256, = .376-.964) were not associated with pain scale sum. Baseline LnRMSSD was associated with pain scale sum ( = -0.663; = .001).
FR did not systematically alter HRV, nor did perceived pain ratings predict HRV responses. Those with lower pre-FR HRV reported higher perceived pain during FR. Basal cardiac autonomic activity may, therefore, influence pain sensitivity to FR in healthy adults.
泡沫轴放松（FR）是一种自我肌筋膜放松技术，其对自主功能的影响尚不清楚，自主功能通过心率变异性（HRV）来衡量。FR可被感知为疼痛或放松，这可能解释个体间HRV反应的差异。
确定急性FR是否会改变静息HRV。第二个目的是确定FR过程中感知到的疼痛是否能预测HRV反应。
学术机构。
采用随机交叉设计，健康成年人（50%为女性）在不同日期进行全身FR或对照操作。在对每个肌肉群进行FR后获得感知疼痛评分，并将其相加得出总体感知疼痛评分。在FR前5 - 10分钟、FR后5 - 10分钟以及FR后25 - 30分钟，测量坐位时的平均RR间期以及连续RR间期差值的均方根的自然对数（LnRMSSD，一种副交感神经HRV指标）。
RR间期（ = 0.105 - 0.561）或LnRMSSD（ = 0.110 - 0.129）未观察到影响。所有效应量范围为微小 - 小（0.00 - 0.26）。RR间期的变化（ = 0.220 - 0.228， = 0.433 - 0.488）和LnRMSSD的变化（ = 0.013 - 0.256， = 0.376 - 0.964）与疼痛量表总和无关。基线LnRMSSD与疼痛量表总和相关（ = -0.663； = 0.001）。
FR未系统性地改变HRV，感知疼痛评分也不能预测HRV反应。FR前HRV较低的人在FR过程中报告的感知疼痛较高。因此，基础心脏自主神经活动可能会影响健康成年人对FR的疼痛敏感性。
