To investigate the cardiorespiratory responses to the 6-min pegboard and ring test (6PBRT) and to assess its reproducibility in healthy adolescents.
It was a cross-sectional study with 52 healthy adolescents (11-18 years old of both genders). The 6PBRT was performed twice on two different days by the same examiner. Intra-rater reliability, percentage of the minimal difference chance (MDC%) and agreement of the number of moving rings were analyzed. Also, cardiopulmonary parameters were collected before and after tests.
Intraclass correlation coefficient (ICC) for the number of rings moved was 0.87 (95%CI 0.69-0.93). The mean number of moved rings during the second test was higher. The MDC% with a 95 % confidence interval was greater than acceptable values. Bland-Altman analysis did not show agreement between measurements (bias = 30.1); with upper and lower limits of agreement of -67.8 to 127.9, respectively. There was a significant increase in dyspnea, fatigue and HR values at the end of the tests (p < 0.0001). In both tests, participants reached HR equivalent to 48 % of the maximum predicted.
Together, the results suggest that the 6PBRT is not a reliable measure for a population of healthy adolescents, which indicates the necessity to perform more than one test. The 6PBRT is suggested to be a submaximal test for this population.
探讨 6 分钟指板和指环测试（6PBRT）对心肺反应的影响，并评估其在健康青少年中的可重复性。
这是一项横断面研究，共有 52 名健康青少年（男女各 11-18 岁）。由同一位检查者在两天内进行两次 6PBRT。分析了内部测试者可靠性、最小差异机会百分比（MDC%）和移动指环数的一致性。此外，还在测试前后收集心肺参数。
移动指环数的组内相关系数（ICC）为 0.87（95%CI 0.69-0.93）。第二次测试中移动的指环数平均值更高。具有 95%置信区间的 MDC%大于可接受值。Bland-Altman 分析显示两次测量之间没有一致性（偏差为 30.1）；分别有-67.8 至 127.9 的上下限协议。在测试结束时，呼吸困难、疲劳和心率值显著增加（p<0.0001）。在两次测试中，参与者的心率均达到预测最大心率的 48%。
综上所述，结果表明 6PBRT 对健康青少年人群来说不是一种可靠的测量方法，这表明需要进行多次测试。对于该人群，6PBRT 被建议为次最大测试。
