目的研究日本乳腺癌存活者心肺功能和腿部力量与体能测试的关系。方法研究对象为50名20~59岁久坐不动的女性，她们在确诊为浸润性乳腺癌(I-IIa期)后2~13个月内接受过乳房手术。心肺功能和腿部力量由最大耗氧量(VO2峰值)和一次最大重复压腿(腿部按压1rm)来衡量。进行6分钟步行试验、座椅站立试验和握力测试。通过多元回归分析，我们建立了VO2峰值和腿部力量的预测方程，基于它们与体能测试的关系。结果平均年龄为48 ± 6年，VO2峰值为25.0 ± 3.6 mg/kg/min，小腿按压1Rm为95 ± 32 kg。多元回归分析得出6分钟步行试验距离、年龄、身高和体重是VO2峰值的预测因子。测定的VO2峰值与预测的VO2峰值呈中度正相关(r= 0.463，p<； 0.001)。座椅站立测试、握力、年龄、身高和体重被选为预测压腿1rm的因素。腿部压力1Rm的预测值与实测值之间存在较强的正相关关系(r= 0.754，p<； 0.001)。然而，可能需要进一步的检查来确定是否可以根据6分钟步行试验来预测心肺功能。
PurposeWe aimed to examine whether cardiorespiratory fitness and leg strength can be estimated based on their relationship with physical performance tests in Japanese breast cancer survivors.MethodsParticipants were 50 sedentary women aged 20 to 59 years who have received breast surgery in the past 2 to 13 months after diagnosis of invasive breast cancer (stage I-IIa). Cardiorespiratory fitness and leg strength were measured by peak oxygen consumption (VO2peak), and one-repetition maximum for leg press (leg press 1RM). Physical performance tests were performed 6-min walk test, chair stand test, and grip strength. Using multiple regression analysis, we developed prediction equations for VO2peak and leg strength based on their associations with the physical performance tests. The validity of the estimation equations was assessed using Bland–Altman plots.ResultsMean age, VO2peak, and leg press 1RM were 48 ± 6 years, 25.0 ± 3.6 mL/kg/min, and 95 ± 32 kg, respectively. Multiple regression analysis yielded 6-min walk test distance, age, height, and body weight as predictors of VO2peak. Measured VO2peak and predicted VO2peak showed a moderate positive correlation (r= 0.463,p< 0.001). Chair stand test, grip strength, age, height, and body weight were selected as predictors of leg press 1RM. There was a strong positive correlation between predicted and measured leg press 1RM (r= 0.754,p< 0.001).ConclusionThe results suggest that leg strength can be predicted using physical performance tests. However, further examination may be needed to determine whether cardiorespiratory fitness can be predicted based on 6-min walk test.
