The aims of the present study were two-fold: to investigate whether, compared to an active control condition, a modified mindfulness-based stress reduction (MBSR) program could (1) reduce symptoms of stress and depression, and (2) regulate salivary cortisol and serum creatine kinase (CK) concentrations, two physiological stress markers.
Thirty male wrestlers ( = 26.73 years) were randomly assigned either to the MBSR intervention or the active control condition. Both at the beginning and at the end of the intervention, the participants completed questionnaires on perceived stress and depression; in parallel, salivary samples were collected to measure cortisol in saliva, while blood samples were collected to assess serum CK. The study lasted for eight consecutive weeks. The intervention consisted of 16 group sessions (90 min each); the active control condition had an identical schedule, though without bona fide interventions. During the study period, the participants kept their sleeping, nutritional and exercising schedules unaltered.
Over time, symptoms of stress and depression decreased; the level of decrease was more prominent in the MBSR condition than the active control condition (significant p values and large effect sizes of interaction). Further, cortisol and creatine kinase concentrations also decreased more in the MBSR condition compared to the active control condition (large effect sizes of interaction).
The present study's findings suggest that among male wrestlers, a modified MBSR intervention have the potential to reduce both psychological (stress and depression) and physiological (cortisol and creatine kinase) indices as compared to an active control condition.
本研究的目的有两个：一是调查与积极对照条件相比，改良的基于正念减压疗法（MBSR）项目是否能够（1）减轻压力和抑郁症状，以及（2）调节唾液皮质醇和血清肌酸激酶（CK）浓度这两种生理应激指标。
30名男性摔跤运动员（平均年龄26.73岁）被随机分配到MBSR干预组或积极对照组。在干预开始和结束时，参与者均完成关于感知压力和抑郁的问卷；同时，收集唾液样本以测量唾液中的皮质醇，收集血液样本以评估血清CK。研究持续八周。干预包括16次小组课程（每次90分钟）；积极对照组有相同的课程安排，但没有真正的干预措施。在研究期间，参与者保持其睡眠、营养和锻炼计划不变。
随着时间的推移，压力和抑郁症状有所减轻；MBSR组的减轻程度比积极对照组更为显著（交互作用的p值显著且效应量较大）。此外，与积极对照组相比，MBSR组的皮质醇和肌酸激酶浓度下降幅度也更大（交互作用的效应量较大）。
本研究结果表明，在男性摔跤运动员中，与积极对照条件相比，改良的MBSR干预有可能降低心理（压力和抑郁）和生理（皮质醇和肌酸激酶）指标。
