167: Stretching Research Roundup

In this episode, Yoga Medicine founder Tiffany Cruikshank and Katja Bartsch take a deep dive into the latest stretching research and what it means for yoga teachers, athletes, and movement professionals. Together, they unpack the latest recommendations around stretching for flexibility, stiffness, strength, hypertrophy, vascular health, recovery, and injury prevention while exploring the limitations of stretching as a standalone tool.

Tiffany and Katja discuss why prolonged static stretching before explosive activity may impair athletic performance, how longer-held yin-style stretches may influence tissue stiffness, and why emerging vascular research around stretching is generating so much interest. They also explore why yoga recovery likely involves far more than just stretching mechanics, including nervous system regulation, breathwork, and relaxation.

“We do not over and not underestimate what stretching can do.” — Katja Bartsch
