Master Your Meathook with Garrett Schniewind

CircSci is back with another episode...this one all about meathooks. Did you think people couldn't talk about meathooks for an hour? You thought wrong! Garrett (@garrettmovement) and I cover risk factors that come up with entering, exiting, and holding meathooks, how to program meathooks over the long run, what meathooks SHOULD look like and more. Did you ever wonder how much to train meathook at first? Total training volume in meathook will vary, but how do we know what too much is for our lil'...

Are There Strength & Performance Changes During Your Hormonal Cycle? Featuring Dr. Lauren Colenso-Semple, Ph.D., CSCS

Have you ever wondered if you might benefit from structuring your training based on your hormonal/menstrual cycle? In this episode, we answer that questions with Dr. Lauren Colenso-Semple. We discuss what she found in her Ph.D research (and the broader literature) when it comes to hormonal cycle changes, performance and strength metrics, and injury rates. We also touch on how the hormonal cycle interacts with hypermobility, and what, if anything should change in response to that. Listen in to fi...

Pain Science and Management for Circus Artists w/Beth Shum, HCPC, MCSP , Circus Physio, and NHS Pain Science Specialist

Beth HCPC, MCSP, (in the US this would be kind of akin to DPT) and I discussed pain science and how it comes into play for professional and recreational circus artists and aerialists answering these questions below: Pain perception - how do you describe and define pain? What is the bare minimum you think a circus artist, coach, and physio should know about pain (and how to assess it) as it relates to circus artists? How do we know what is “okay” pain vs. bad pain? What are patterns of pain among...

Creativity and Variability in Circus Training and Pedagogy ft. Adam Woolley

You'll just have to listen to this one for the full description but below are some key take-aways! Takeaways: Incorporating variability and creativity in circus training and teaching is essential for skill development AND personal expression. Pedagogical approaches should be rooted in beliefs about learning and should align with the values of the coach and the student. Creativity can be fostered in students through intentional scaffolding and opportunities for personal input. Variability and cre...

The Utility of Movement Screens In Aerial/Circus ft. Dr. Monica Warren (Epidemiologist & Physical Therapist) and Dr. Monica Lininger (Athletic Trainer and Ph.D in Measurement and Evaluation).

In this episode, I had two amazing researchers, Dr. Meghan Warren (epidemiologist/physical therapist from the Patient Centered Outcomes Research Institute, and research specialist/athletic trainer, Dr. Monica Lininger from NAU, who extensively researched the Functional Movement Screen and movement screens in general.

Tendon training and adaptation (in circus and hyper mobility) for performance and recovery ft. Dr. Keith Baar, Molecular Biologist

Y'all are going to love this one. Keith Baar joined myself and special guest co-host Max March-Steinman on this episode all about the molecular properties of tendons, their adaptive responses, and how to appropriately modify your training techniques depending on if you're interested in power, strength, range of motion (and maybe some things not to do), or stability (in the case of hypermobility). We also briefly touch on the dietary sources of the nutrients that support healthy tendons. During t...

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, humble, passionate, and admit when a question or idea is beyond their scope of knowledge.
