ᅟ: Exercise can improve quality of life (QOL) in breast cancer survivors. In contrast to many group or home-based exercise programs, little is known about the effectiveness of goal-oriented recreational activities.
The purpose of this study was to evaluate a clinically overseen team triathlon training program on improving physiological and psychosocial health-related measures in female breast cancer survivors.
Twenty-three participants (age = 48 (8), BMI = 25 (1), mean (SE)) were recruited from a 14-week sprint triathlon (800-m swim, 20-km bike, 5-km run) team training program for women breast cancer survivors (4 (3) years post-surgery, chemo-, or radiation-therapy). Training included two supervised group and three home-based individual sessions per week. Pre- and post-training outcomes included isokinetic knee extensor strength (60, 180, and 300° s), 6-min walk test (6MWT), maximal oxygen uptake (VO max), QOL (Functional Assessment of Cancer Therapy -Breast (FACT-B)), and barriers to exercise. Outcomes were also obtained 6 months post except for VO max. Significance was set at p < 0.05.
Data are mean (SD) from 21 complete data sets. Knee extensor peak torque significantly improved only at 300° s (pre 40.3(8.5) ftlb; post 45.2(8.4); p = 0.001). 6MWT significantly improved (pre 632.8(62.1) m; post 657.4(53.2); p = 0.014) as did VO max (pre 31.3(5.8) ml kg min; post 35.9(5.8); p < 0.001). FACT-B also improved (pre 114(12); post 122(13); p = 0.004), including the FACT-G total score, social well-being, and breast cancer subscales while barriers to exercise decreased (pre 54(12); post 36(9); p < 0.001). Strength, 6MWT, and barriers to exercise remained improved after 6 months.
Team triathlon training in breast cancer survivors can increase aerobic capacity and improve QOL which may contribute to healthier lifestyles in breast cancer survivors.
有研究表明，运动可以改善乳腺癌幸存者的生活质量（QOL）。与许多团体或居家运动项目不同，关于目标导向性娱乐活动的有效性知之甚少。
本研究旨在评估一项由临床监督的团队铁人三项训练计划对改善女性乳腺癌幸存者生理和心理社会健康相关指标的效果。
从一项为期14周的女子乳腺癌幸存者短距离铁人三项（800米游泳、20公里自行车、5公里跑步）团队训练计划中招募了23名参与者（年龄 = 48（8）岁，体重指数 = 25（1），均值（标准误））。这些参与者均在乳腺癌手术后、化疗或放疗后4（3）年。训练包括每周两次有监督的团体训练和三次居家个人训练。训练前后的指标包括等速膝关节伸肌力量（60、180和300°/秒）、6分钟步行试验（6MWT）、最大摄氧量（VO₂max）、生活质量（癌症治疗功能评估 - 乳腺癌（FACT - B））以及运动障碍。除VO₂max外，在训练后6个月也获取了相关指标。显著性设定为p < 0.05。
数据为21个完整数据集的均值（标准差）。仅在300°/秒时膝关节伸肌峰值扭矩显著改善（训练前40.3（8.5）英尺磅；训练后45.2（8.4）；p = 0.001）。6MWT显著改善（训练前632.8（62.1）米；训练后657.4（53.2）；p = 0.014），VO₂max也显著改善（训练前31.3（5.8）毫升/千克/分钟；训练后35.9（5.8）；p < 0.001）。FACT - B也有所改善（训练前114（12）；训练后122（13）；p = 0.004），包括FACT - G总分、社会幸福感和乳腺癌分量表，同时运动障碍减少（训练前54（12）；训练后36（9）；p < 0.001）。6个月后力量、6MWT和运动障碍仍保持改善。
乳腺癌幸存者的团队铁人三项训练可以提高有氧能力并改善生活质量，这可能有助于乳腺癌幸存者更健康的生活方式。
