To determine which mode of exercise is preferred by breast cancer survivors and to evaluate this response between graded exercise testing on a treadmill and on a cycle ergometer.
Twelve breast cancer survivors completed 2 maximal aerobic stress tests on separate days. The women completed a ramp protocol on an electronically braked cycle ergometer and an incremental step protocol on a treadmill to volitional fatigue. Test order was randomized. Expired gases were collected for the determination of peak aerobic capacity (Vo (2peak)).
Exercise mode had a significant effect on the graded exercise response in breast cancer survivors, P = .003. Treadmill Vo (2peak) was significantly greater than bike Vo (2peak) (28.7 ± 4.7 vs 23.9 ± 4.7 mL/min/kg, respectively, P = .003) and VE(max) was equivalent between exercise modes (P = .731). Maximal heart rate was significantly higher by 11 bpm during the treadmill protocol (P = .004), and Ve/VCo (2) exhibited possible mode dependency (P = .018).
This patient population felt more comfortable and produced significantly greater Vo2(peak) values using the treadmill protocol. These results discuss the potential implications concerning the design and interpretation of exercise interventions for breast cancer survivors.
确定乳腺癌幸存者更喜欢哪种运动模式，并评估在跑步机和固定自行车上进行分级运动测试时的这种反应。
12 名乳腺癌幸存者在不同的日子里完成了 2 次最大有氧应激测试。女性在电子制动固定自行车上完成斜坡方案，在跑步机上完成递增步方案，直至达到疲劳。测试顺序是随机的。收集呼出气体以确定最大有氧能力（Vo(2peak)）。
运动模式对乳腺癌幸存者的分级运动反应有显著影响，P =.003。跑步机 Vo(2peak)显著高于自行车 Vo(2peak)（分别为 28.7 ± 4.7 与 23.9 ± 4.7 mL/min/kg，P =.003），而最大摄氧量（VE(max)）在运动模式之间相等（P =.731）。在跑步机方案中，最大心率显著高 11 bpm（P =.004），并且 Ve/VCo(2)表现出可能的模式依赖性（P =.018）。
该患者群体在使用跑步机方案时感觉更舒适，并产生了显著更高的 Vo(2peak)值。这些结果讨论了设计和解释乳腺癌幸存者运动干预措施的潜在意义。
