While general guidelines (such as CONSORT or Consensus on Exercise Reporting Template) exist to enhance the reporting of exercise interventions in the field of exercise science, there is inadequate detail facilitating the standardized reporting of resistance training adherence in the oncology setting. The purpose of this study was to apply a novel method to report resistance training dose, adherence, and tolerance in patients with cancer.
A total of 47 prostate cancer patients (70.1 ± 8.9 yr, body mass index, 28.6 ± 4.0) with bone metastatic disease completed an exercise program for 12 wk. We assessed traditional metrics of adherence (attendance and loss to follow-up), in addition to novel proposed metrics (exercise-relative dose intensity, dose modification, and exercise interruption). Total training volume in kilograms (repetitions × sets × training load (weight)) was calculated for each patient.
Attendance assessed from traditional metrics was 79.5% ± 17.0% and four patients (9%) were lost to follow-up. The prescribed and actual cumulative total dose of resistance training was 139,886 ± 69,150 kg and 112,835 ± 83,499 kg, respectively, with a mean exercise-relative dose intensity of 77.4% ± 16.6% (range: 19.4% -99.4%). Resistance training was missed (1-2 consecutive sessions) or interrupted (missed ≥3 consecutive sessions) in 41 (87%) and 24 (51%) participants, respectively. Training dose was modified (reduction in sets, repetitions, or weight) in 40 (85%) of patients. Importantly, using attendance as a traditional metric of adherence, these sessions would have all counted as adherence to the protocol.
Traditional reporting metrics of resistance training in exercise oncology may overestimate exercise adherence. Our proposed metrics to capture resistance training dose, adherence, and tolerance may have important applications for future studies and clinical practice.
虽然有一般指南（如 CONSORT 或运动报告模板共识）存在，以提高运动科学领域的运动干预报告，但在肿瘤学环境中，标准化报告抵抗训练依从性的细节不足。本研究的目的是应用一种新方法报告癌症患者的抵抗训练剂量、依从性和耐受性。
共有 47 名患有骨转移疾病的前列腺癌患者（70.1 ± 8.9 岁，体重指数 28.6 ± 4.0）完成了 12 周的运动计划。我们评估了传统的依从性指标（出勤率和随访丢失），以及新提出的指标（运动相关剂量强度、剂量调整和运动中断）。为每个患者计算了公斤（重复次数×组数×训练负荷（重量））的总训练量。
传统指标评估的出勤率为 79.5% ± 17.0%，有 4 名患者（9%）随访丢失。规定的和实际的累积阻力训练总剂量分别为 139886 ± 69150kg 和 112835 ± 83499kg，平均运动相关剂量强度为 77.4% ± 16.6%（范围：19.4%-99.4%）。41 名（87%）和 24 名（51%）参与者分别错过了（1-2 个连续的课程）或中断了（错过≥3 个连续的课程）阻力训练。40 名（85%）患者的训练剂量进行了调整（减少组数、重复次数或重量）。重要的是，使用出勤率作为依从性的传统指标，这些课程都将被视为对方案的依从。
运动肿瘤学中抵抗训练的传统报告指标可能高估了运动的依从性。我们提出的捕捉抵抗训练剂量、依从性和耐受性的指标可能对未来的研究和临床实践有重要的应用。
