Abstract

Yoga-based exercise has proven to be beneficial for practitioners, including cancer survivors. This study reports on the improvements in physical fitness for 20 breast cancer survivors who participated in a six-month yoga-based exercise program (YE). Results are compared to a comprehensive exercise (CE) program group and a comparison (C) exercise group who chose their own exercises. "Pre" and "post" fitness assessments included measures of anthropometrics, cardiorespiratory capacity, strength and flexibility. Descriptive statistics, effect size (d), dependent sample t tests for all outcome measures were calculated for the YE group. Significant improvements included: decreased % body fat (-3.00%, d =-0.44, p < 0.001); increased sit to stand leg strength repetitions (2.05, d = 0.48, p = 0.003); forward reach (3.59 cm, d = 0.61, p = 0.01); and right arm sagittal range of motion (6.50°, d = 0.92, p = 0.05). To compare YE outcomes with the other two groups, a one-way analysis of variance (ANOVA) was used. YE participants significantly outperformed C participants on "forward reach" (3.59 cm gained versus-2.44 cm lost), (p = 0.009) and outperformed CE participants (3.59 cm gained versus 1.35 cm gained), but not statistically significant. Our results support yoga-based exercise modified for breast cancer survivors as safe and effective.
