Therapeutic Yoga Research

Our Dedicated Participation to Yoga Research

Nydia’s Yoga Therapy Studio has been successful in participating in Yoga Research.
Owner, Nydia Tijerina Darby, has developed protocols for the Yoga Asana practices utilized in the research programs. She has also mentored and trained the yoga teachers in the protocol and has supervised the programs on site at the studio. The NYT Yoga Research Team is the first of its kind and is recognized by the International Association of Yoga Therapists as a program that offers 200 hours of specialized continuing education for certified yoga instructors.

Nydia’s Yoga Therapy Yoga Research Team presented two research posters at the Symposium on Yoga Research (SYR) at the Kripalu Center for Yoga & Health in Massachusetts on September 24-26th 2014.

  • Nydia Tijerina Darby, PT, DPT presented “A Structured and Combined Yoga Asana & Pranayama Intervention for Post-Treatment Breast Cancer Survivors.”
  • Terri Boggess, PhD presented “Effect of a six month yoga exercise intervention on fitness outcomes for breast cancer survivors.”


SYR is the West’s foremost academic yoga research conference. It showcases some of the best new research and offers multiple poster sessions as well as ample opportunities to interact with other scientists, experts and professionals in the field. SYR 2014 will be held at the Kripalu Center for Yoga & Health in the beautiful Berkshires in western Massachusetts.

Current Research


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 (YE) exercise program. 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.
