To determine the effect of warm-up on anthropometric measures, 10 patients with ankylosing spondylitis and 10 normal control subjects were measured over a 1-hour period by one therapist. A series of 4 measures--a modified Schober's test, finger-to-floor with the subject standing on a 23-cm stool, chest expansion, and cervical rotation using an arthrodial protractor--were repeated completely 4 times. Subjects exercised between each series (except between the third and fourth series). Intra-rater reliability was determined by comparing measurement 3 with measurement 4, and the warm-up effect was determined by comparing measurement 1 with measurement 3. The Schober's test and chest expansion are stable measures and are not affected by warm-up. However, the finger-to-floor and cervical rotation exercises require warm-up to ensure stable values for clinical or research followup of spondylitis.
为确定热身对人体测量指标的影响，一名治疗师在1小时内对10名强直性脊柱炎患者和10名正常对照者进行了测量。一系列4项测量指标——改良Schober试验、受试者站在23厘米高的凳子上手指触地、胸廓扩张以及使用关节量角器测量颈椎旋转——完整重复进行4次。在每个测量系列之间（第三和第四系列之间除外）受试者进行锻炼。通过比较第三次测量与第四次测量来确定评估者内部信度，通过比较第一次测量与第三次测量来确定热身效果。Schober试验和胸廓扩张是稳定的测量指标，不受热身影响。然而，手指触地和颈椎旋转运动需要进行热身，以确保在强直性脊柱炎的临床或研究随访中获得稳定的值。
