Abstract

Topics in Exercise Science and Kinesiology Volume 4: Issue 1, Article 4, 2023. Phase angle (PhA) has emerged as a prognostic indicator of survival and quality of life (QOL) in cancer patients. Identifying measures of physical fitness that correlate with PhA can provide guidance toward optimizing cancer rehabilitation programs and future research. The purpose was to examine the relationship between PhA and physical fitness in breast cancer survivors. Sixty-three breast cancer survivors (60 ± 9 years, PhA 4.59±0.52, mean±SD) completed assessments for muscular strength, muscular endurance, cardiorespiratory endurance, flexibility, and body composition. PhA and body composition were measured using bioimpedance analysis (Inbody 770) at 50 KHz. The correlations between phase angle and measures of fitness were evaluated using Pearson coefficients. Simple and multiple linear regression was used to test if measures of muscular strength, muscular endurance, and cardiorespiratory endurance predict PhA. Linear regression analysis showed that incline bench press 1-RM alone explains 28% (r2 = 0.28; P2peak explain 32% (r2 =0.32; PThe prioritization of muscular strength for improving PhA in exercise-based cancer rehabilitation programs may be of importance.
