This study aimed to compare the effects of isocaloric polarized and threshold training intensity distribution on endurance capacity in breast and prostate cancer survivors. A total of 28 breast and 27 prostate cancer survivors were randomly assigned to a polarized (POL, n = 27 (13 women), age 60 ± 8 years, peak oxygen uptake (VO) 23 mL·min kg), or threshold training group (ThT, n = 28 (15 women), age 59 ± 10 years, VO 23 mL·min kg) who completed two sessions per week on a cycle ergometer over 12 weeks. Exercise duration was adapted to obtain equivalent energy expenditure in both groups. Cardiopulmonary exercise and verification tests were performed to determine endurance capacity (VO, peak power output (PPO), ventilatory threshold (VT), blood lactate thresholds (LT and IAT)), and maximal exhaustion. POL did not achieve the planned polarized intensity distribution and rather performed a pyramidal training. Pyramidal and threshold training significantly (p < 0.001) improved endurance capacity regarding VO (0.09 and 0.12 L·min), PPO (27 and 17W), power output at VT (11 and 13W), oxygen uptake at VT (0.09 and 0.11 L·min), power output at LT (7 and 12W), and power output at IAT (12 and 14W). No difference was found between groups, but ThT required significantly (p < 0.001) less time than pyramidal training to achieve the described improvements (59 ± 1 min/week vs. 76 ± 11 min/week). Comparison of isocaloric training intensity distributions revealed no significant differences between groups (Pyramidal: 170 ± 43 kJ/session, ThT: 175 ± 35 kJ/session, p = 0.10). Pyramidal and isocaloric threshold training resulted in comparable effects on endurance capacity in cancer survivors, with ThT requiring significantly less time for these effects.
本研究旨在比较等热量极化训练强度分布和阈强度训练强度分布对乳腺癌和前列腺癌幸存者耐力的影响。共有28名乳腺癌幸存者和27名前列腺癌幸存者被随机分配到极化训练组（POL，n = 27（13名女性），年龄60±8岁，峰值摄氧量（VO）23 mL·min·kg）或阈强度训练组（ThT，n = 28（15名女性），年龄59±10岁，VO 23 mL·min·kg），两组均在12周内每周在功率自行车上完成两次训练。训练时长进行了调整，以使两组的能量消耗相当。进行心肺运动和验证测试以确定耐力（VO、峰值功率输出（PPO）、通气阈（VT）、血乳酸阈（LT和IAT））以及最大耗竭量。POL未实现计划的极化强度分布，而是进行了金字塔式训练。金字塔式训练和阈强度训练在VO（分别提高0.09和0.12 L·min）、PPO（分别提高27和17W）、VT时的功率输出（分别提高11和13W）、VT时的摄氧量（分别提高0.09和0.11 L·min）、LT时的功率输出（分别提高7和12W）以及IAT时的功率输出（分别提高12和14W）方面均显著（p < 0.001）提高了耐力。两组之间未发现差异，但与金字塔式训练相比，ThT达到上述改善所需时间显著更少（p < 0.001）（分别为59±1分钟/周和76±11分钟/周）。等热量训练强度分布的比较显示两组之间无显著差异（金字塔式训练：170±43 kJ/次训练，ThT：175±35 kJ/次训练，p = 0.10）。金字塔式训练和等热量阈强度训练对癌症幸存者的耐力产生了相似的影响，且ThT产生这些影响所需时间显著更少。
