Embracing Adaptation through Pain Science, When to use RPE, Self-efficacy in Coaching, and How to Craft an Effective Warm-up ft. Tait Brown, Clinical Exercise Physiologist
In this episode of CircSci, we cover aspects of pain science (and how tissue damage may not be as bad as we think), RPE scale usage (for strength versus skills), self-efficacy in coaching and rehab, and more (like some potential aspects of a good warm-up). Tait Brown is an Accredited Exercise Physiologist, and is incredibly knowledgable in the field of Allied Health and is about as hilarious

Janelle is a contortionist, aerial

Autoregulation, Minimum Effective Dose, and Oral Contraceptive Use on Maximal Strength Output (ft. Dr. Eric Helms)
Ever been curious about how to assess when to stop training a dynamic aerial skill versus a strength skill? In this episode of CircSci, we explore the way you can use autoregulation and repetitions left in reserve to pick sets/reps and load for differing types of exercise and skills.
Throughout my coaching and academic careers, I’ve always looked up to experts who: were constantly learning, humbl

Hormonal Cycle Periodization - The Pun Wasn't Made
Interview with Jess Allen - @awyrol - who is an aerial instructor/performer in Wales, has completed two PhD's, and has spent the pandemic looking into periodization into relation to hormonal changes because she's a bit mental (in the best way!).
