Given the effects of inspiratory muscle training (IMT) on exercise tolerance of Breast Cancer survivor (BCS) and since IMT load is adjusted based on Maximal Inspiratory Pressure (MIP), the aim of this study was to evaluate MIP of BCS, compare it with the obtained from predictive equations for healthy women, and study the possible effects of physical activity level on it.
MIP was obtained from 50 BSC and compared with the theoretical values of MIP estimated through predictive equations of Black & Hyatt, and Hautmann. BCS were categorized in 25 active and 25 sedentary according to HUNT1-PAQ questionnaire.
Measured MIP (65.5 ± 23.9 cm HO) was significative lower than predicted by equations (21.4% and 14.0%, Black & Hyatt and Hautmann equations, respectively), specially because of MIP of those BCS who did not meet the minimum physical activity recommended.
The results of this study clearly show than MIP is lower than the predicted by equations in BCS and suggests the importance of measuring it, not only for adjust the load of future IMT interventions, but also to evaluate the effects of exercise programs on it.
鉴于吸气肌训练（IMT）对乳腺癌幸存者（BCS）运动耐力的影响，且IMT负荷是根据最大吸气压力（MIP）进行调整的，本研究旨在评估BCS的MIP，将其与通过健康女性预测方程得出的结果进行比较，并研究身体活动水平对其可能产生的影响。
从50名BCS中获取MIP，并与通过Black&Hyatt和Hautmann预测方程估算的MIP理论值进行比较。根据HUNT1-PAQ问卷，将BCS分为25名活跃组和25名久坐组。
测得的MIP（65.5±23.9cmHO）显著低于方程预测值（分别比Black&Hyatt方程和Hautmann方程低21.4%和14.0%），特别是那些未达到推荐最低身体活动量的BCS的MIP。
本研究结果清楚地表明，BCS的MIP低于方程预测值，这表明测量MIP很重要，不仅用于调整未来IMT干预的负荷量，还用于评估运动计划对其产生的影响。
