What's up everybody? Before we get rolling, I'd love to share a bit about Jane, the practice management software that we love and use here at ICE who are also our show sponsor. Jane knows that collecting new patient info, their consent and signatures can be a time consuming process, but with their automated forms, it does not have to be. With Jane, you can assign intake forms to specific treatments or practitioners, and Jane takes care of sending the correct form out to your patients. Save even more time by requesting a credit card on file through your intake forms with the help of Jane Payments, their integrated PCI compliant payment solution. Conveniently, Jane will actually prompt your patients to fill out their intake form 24 hours before their appointment if they have not done so already. If you're looking to streamline your intake form collection, head over to jane.app slash physical therapy, book a one-on-one demo with a member of the Jane team. They'll be able to show you the features I just mentioned and answer any other questions you may have. Don't forget, if you do sign up, use the code ICEPT1MO for a one month grace period applied to your new account. Thanks everybody, enjoy the show.

Good morning everybody, welcome to the PT on ICE Daily Show. Happy Friday morning, I hope your day is off to a great start. My name is Alan, happy to be your host today. Currently have the pleasure of serving as the Chief Operating Officer here at ICE and lead faculty here in our fitness athlete division. It is Fitness Athlete Friday, we would argue it's the best start day of the week. We talk all things CrossFit, functional fitness, powerlifting, Olympic weightlifting, endurance athletes, runners, bikers, swimmers, everything related to the person who's regulationally active here on Fridays. Before we get started with today's topic, we're going to be tackling mobility. We're going to define mobility versus flexibility. We're going to discuss a recently published paper showing the effects of long term stretching on mobility changes and address concerns related to that paper. Before we get started, let's talk about a couple of announcements. It is the CrossFit Games individual and team competitions began yesterday. Age group and adaptive athletes began Tuesday. We have a day competition all week long. You can catch it on ESPN. You can catch it on YouTube. Our very own Kelly Benfee here from the fitness athlete division will be competing with her team. Plus 64 CrossFit Army end game in the team division. So you can check her out. She had a couple of events yesterday and she's got events every day the rest of the weekend. Speaking of fitness festivals, the I Got Your Six Fitness Festival will be June 21st and 23rd down in Charleston, South Carolina with our friends at Warrior WOD. We had the virtual competition this year, but next year it's going to be in person. So it's a ways away, but look forward to that calendar if you want to come down to Charleston and join us for a weekend of approachable fitness courses coming away from us here in the fitness athlete division. Your next chance to catch our live course will be September 9th and 10th. That will be in Bismarck, North Dakota with Mitch Babcock or the end of September, September 30th and October 1st. You can catch Zach Long out on the West Coast. He'll be in Newark, California. That's in the Bay Area. Our online courses, Clinical Management Fitness Athlete Essential Foundations, our eight week entry level online course begins again September 11th and Fitness Athlete Advanced Concepts, our level two online course begins September 17th. So mobility, let's talk about it. How much can we really move the needle? My goal today is to define mobility as it's often talked about in kind of common terms with athletes in the gym, patients in the clinic when they talk about mobility, defining mobility versus defining flexibility. Talking about a paper that was published a couple of weeks ago, looking at the effects of long term stretching specifically at ankle mobility, which is a joint we're always after to improve the range of motion within and then really how to approach mobility from a practical clinical standpoint.

2:01 EFINING MOBILITY VS. FLEXIBILITY So let's start first with defining mobility versus flexibility because they're often used interchangeably and that's not the correct way to use them. Then when we talk about flexibility, we're talking about the capacity of soft tissues of muscles, tendons, ligaments to be passively stretched, whether me as the therapist stretches you the patient or whether you stretch yourself using your own body, using stretch straps, things like that. The ability to passively stretch muscle tissue at a specific joint. Now mobility is different. Mobility is the ability of a joint to actively move through a range of motion. And of course, we're always chasing a full range of motion. So the ability, for example, of the need to advance across the toes in active closed chain dorsiflexion, the ability of the hip to externally rotate or flex sitting down into a squat, that would be an assessment of mobility, actively moving the joint through the range of motion. And you, the patient or athlete moving yourself through the range of motion, aka how much motion can you actually access? Because we see some folks have a big difference between their flexibility and their mobility. We may be able to passively move their ankle, passively move their leg into a normal or above average range of motion. But when that person stands up, they re-encounter gravity and they try to actively move that joint. We can sometimes see a big difference between mobility and flexibility. And that brings us to a really important point that a lot of what we see in marketing, in programs, in our own home programs for athletes and patients is that we say we're prescribing mobility. But really, what we are giving for the most part is flexibility, that a lot of passive stretching is what is given out, which can improve flexibility. Yes, but may not always result in any sort of functional change in mobility. We see a ton of programs all over social media, especially in the fitness athlete space, that are marketed at improving mobility. But when we actually look at the content of those programs, things like ROMWOD, things like GOWOD, things like whatever WOD, that we actually see a lot of passive stretching, a lot of flexibility. And so it's no wonder that folks come in and have been doing one of these programs for weeks, months, years, and have not seen any sort of beneficial improvements. In their mobility, their ability to actively move joints through a range of motion, because they have not been doing any sort of mobility work, they have been doing a lot of flexibility work. And we know those two things don't always translate. We don't always see a bunch of flexibility work translate into any sort of improvements in actual meaningful functional mobility.

7:32 THE RESEARCH ON STRETCHING So what does the research say? There's a bunch of research on passive stretching. There's a bunch of research on the benefits specifically of eccentric loading to improve range of motion, to improve active mobility. And we've always kind of wondered the question of what is the dose response relationship with flexibility training, with stretching? We have a great paper that came out last month in the Journal of Strength and Conditioning Research by Wernicke and colleagues. I'll post the link on Instagram and in the show notes on the podcast that sought to answer that question. So this was a study that sought to look at the effects on maximal voluntary muscular contraction, flexibility and muscle thickness of the ankle plantar flexors. Now, the experimental group had a lot of stretching prescribed. Specifically, they stretched six times a day for 10 minutes each session for six weeks. So about 42 total hours of stretching through the calf complex, an hour per day for 42 days. They perform the stretching with a night splint type orthotic of a boot that prepositions the foot into ankle dorsiflexion with the addition of a strap assist to pull their ankle into additional dorsiflexion if able. So essentially stretching the gastric complex 10 minutes, six times a day for six weeks. Now, what did the results show? The results did show an improvement in range of moti
