Podcasts about Impedance

In the first episode of Fund/Build/Scale, Mayfield Managing Partner Navin Chaddha spoke about the need for founders to identify investors they can trust, how to pitch Mayfield's AI Start seed fund, and why he's specifically looking for inception-stage entrepreneurs who have “half-baked” ideas. Our conversation covered a lot of ground: Navin described the elements of a fundable idea, shared what excites (and unnerves) him about AI investing, and offered a framework for founder teams seeking solutions to orthogonal problems that create value for customers and align with market trends. Here's an episode rundown: 1:07: AI investing and entrepreneurship 7:56: fundraising, enterprise opportunities and success metrics 17:27 the biggest challenges facing AI investors 19:11: what strong founder teams look like 22:10: leveraging inception-stage investors 26:47: why idea-stage founders shouldn't worry about revenue 31:36: pitfalls/opportunities at the enterprise level 34:25: the "impedance mismatch" between startups + enterprise customers 38:22: societal change + responsible innovation 42:48: how he educates himself about emerging tech Coming up in Episode 2: I spoke with Rodrigo Liang, CEO and co-founder of SambaNova, about digging a moat, customer discovery, and product-led growth.

This week's EYE ON NPI is going to fuel up your portable battery-powered designs with the Texas Instruments BQ27427 System-Side Impedance Track™ Single-Cell Battery Fuel Gauge (https://www.digikey.com/en/product-highlight/t/texas-instruments/bq27427-single-cell-battery-fuel-gauge) a powerful and inexpensive way to add high quality battery monitoring for charge-rate and aging tracking at the system side. Lithium Ion / Polymer batteries (https://www.digikey.com/en/products/filter/batteries-rechargeable-secondary/91) - you love them for their low cost, high power density, and 3.7V nominal voltage, but keeping them recharged and letting people know exactly how much battery life is left is non-trivial. Like most batteries, common LiPoly/LiIon's start with a high peak voltage right after charging of about 4.2V, drop quickly to about 3.7V and then slowly drift down till they get to 3.0V at which point the cut-off circuitry disconnects until they are recharged. It's really easy to tell when the battery is 90% or greater charge, just look for a voltage of 3.9V or higher. It's also pretty easy to tell when they're 10% or less, the voltage will be 3.3V or lower. But that in-between section is tough because the slope during discharge is very shallow and the voltage changes quite a bit with aging, temperature, and discharge rate (https://www.ti.com/lit/an/snva533/snva533.pdf) So while there are battery monitors that can use just the voltage across the battery terminals, they're not going to be as precise as a coulomb-counter design that takes into account both voltage and current. From TI's White Paper on the topic (https://www.ti.com/lit/wp/slpy002/slpy002.pdf): "An impedance-based battery fuel gauge, as the name implies, uses the measured impedance of the battery's cells as a key input to its remaining capacity predictions. The gauge measures and stores in real-time the battery pack's resistance as a function of state-of-charge. The real-time resistance profiles along with the stored battery open-circuit voltage tables (open-circuit voltage vs. state-of-charge) enables the gauge to predict the battery pack's discharge curve (by adjusting for the IR drop) under any system-use condition and temperature. The algorithm uses current integration (coulomb counting) when the system is ON, and open-circuit voltage measurement when the system is OFF or in SLEEP to adjust remaining state-of-charge (RSOC) up or down (for charge or discharge) the predicted discharge curve. By using the predicated discharge curve, the gauge can accurately calculate the battery pack's remaining discharge capacity (RM) and the system's run-time to empty (RTTE). Since an impedance track gauge continuously adjusts RM and FCC for impedance and the change in impedance, rate and temperature inefficiencies and aging are inherently taken into account, enabling the gauge to maintain a high level of accuracy throughout the life of the system." Texas Instruments has a few chips in the Impedance Track family (https://www.ti.com/video/6287050244001) - the BQ27427 charger (https://www.digikey.com/en/products/detail/texas-instruments/BQ27427YZFR/17748369) is the latest to come out. It's very small, coming as a 9-pin 1.6x1.6 BGA with the center pad being a shared ground so you don't need plugged vias to use. It's also really easy to use, requiring only 2 small stabilization capacitors. Internal temperature monitoring means you don't need a separate thermistor. The high-side 7 mΩ current sense resistor also means one less part on the BOM. I2C pins are used to communicate with the monitor and set battery characteristics. There's also an optional input that can be used to connect to a mechanical or electrical battery insertion switch or to an external thermistor, and an optional output that can be used as a battery low indicator. Because so much is integrated, and the chip is so small, its very easy to pop it into your design between the battery terminal and the VBAT lines that go to your battery charger and power supply. The peak battery voltage and capacity are easy to look up since they're written on the battery. For other configuration settings you can use BQStudio / GaugeStudio (https://www.ti.com/tool/BQSTUDIO) with the TI battery devboard to characterize and customize the learning cycle. Either way, you will need to write the configuration to the sensor on every boot. Pick up the Texas Instruments BQ27427 (https://www.digikey.com/short/18pb1ftw) and other chips from the Impedance Track family (https://www.digikey.com/en/products/result?s=N4IgjCBcoLQCxVAYygMwIYBsDOBTANCAG4B2aWehA9lANrhwCsAnBALqEAOALlCCAF8hQA0) stocked at DigiKey for immediate shipment.

Robert C. Hyzy, MD, Professor of Medicine in the Division of Pulmonary and Critical Care at the University of Michigan in Ann Arbor and Medical Director of the Critical Care Medicine Unit at the University of Michigan Hospital presents at Critical Care Grand Rounds with a lecture entitled, "Electrical Impedance Tomography Use in ARDS." 

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.03.20.533519v1?rss=1 Authors: Kelley, C., Antic, S. D., Carnevale, N. T., Kubie, J. L., Lytton, W. Abstract: Rhythmic activity is ubiquitous in neural systems, and impedance analysis has been widely used to examine frequency-dependent responses of neuronal membranes to rhythmic inputs. Impedance analysis assumes the neuronal membrane is a linear system, requiring the use of small signals to stay in a near-linear regime. However, postsynaptic potentials are often large and trigger nonlinear mechanisms. We therefore augmented impedance analysis to evaluate membrane responses in this nonlinear domain, analyzing responses to injected current for subthreshold membrane voltage (Vmemb), suprathreshold spike-blocked Vmemb, and spiking in a validated neocortical pyramidal neuron computer model. Responses in these output regimes were asymmetrical, with different phase shifts during hyperpolarizing and depolarizing half-cycles. Suprathreshold chirp stimulation gave equivocal results due to nonstationarity of response, requiring us to use fixed-frequency sinusoids. Sinusoidal inputs produced phase retreat: action potentials occurred progressively later in cycles of the input stimulus, resulting from adaptation. Conversely, sinusoidal current with increasing amplitude over cycles produced a pattern of phase advance: action potentials occurred progressively earlier. Phase retreat was dependent on Ih and Iahp currents; phase advance was modulated by these currents. Our results suggest differential responses of cortical neurons depending on the frequency of oscillatory input in the delta -- beta range, which will play a role in neuronal responses to shifts in network state. We hypothesize that intrinsic cellular properties complement network properties and contribute to in vivo phase-shift phenomena such as phase precession, seen in place and grid cells, and phase roll, observed in non-place cells in hippocampus.

We apologize for our extended break! Chris has been hard at work from morning til late at night every day setting up Worthington's two new Fuji pick and place machines. Now that some of the dust has settled we hope to get back on a more regular recording schedule. We've had several requests from our listeners to have an episode on on impedance control, which is unfortunately a topic Chris and Melissa have little expertise on. Fortunately we were able to connect with Ryan Miller from NCAB group who specializes in the subject and kindly agreed to come on the show to give  us a lesson on what impedance control is, in what situations is it necessary, and more. 

Recently I did a fun little experiment on myself.  I did a BIA (Bioelectrical Impedance Analysis) scan BEFORE a 1-hour gym session and again immediately AFTER. I was inundated with requests to share what happened and why I don't recommend these scans. So here are the results:   BEFORE TRAINING Weight: 61kg. The report suggested I needed to gain 1kg to get to 62kg Height: 169.8cm Skeletal Muscle Mass: 25.9kg Body Fat %: 23.1% Visceral Fat Level: 5 BMR: 1383kcal Bone Mineral Content: 2.95kg   AFTER TRAINING Weight: 61.1kg. The report suggested I needed to lose 0.3kg to get to 60.8kg by increasing 0.7kg of muscle and decreasing 1kg of fat Height: 168.2cm - I shrunk Skeletal Muscle Mass: 25.4kg - I lost 0.5kg of muscle Body Fat %: 24.6%. Increased by 1.5%!! Gained 900g fat Visceral Fat Level: 6 - increased BMR: 1365kcal - decreased Bone Mineral Content: 2.84kg - decreased   Hopefully, this highlights that these scans are not the best tool for monitoring changes in body composition. They are very easy to manipulate and results can vary significantly - up to 8% variance has been seen in the literature!  If I can gain 900g of body fat, lose 500g of muscle and gain almost a centimetre in my arm circumference in an hour - what hope do you have of assessing accurate change over 4 weeks?! There is absolutely no point in measuring something if it cannot accurately track progress. Save your $.

Today we're going all-out with the construction analogies. Yes, it's poetic. But it's also pretty darn insightful and valuable.    When you're a part of an organization, you pass information up and down the line all the time. If you fail to be a reliable link in that information chain, things fail to function smoothly. In electrical terms, if you fail to ensure that the current of information moves efficiently up and down the wire, you're causing impedance.   When you notice this, seek to resolve the issue by connecting the parties who need to pass information back and forth. Put them in touch with one another in order to increase the quality and efficiency of your organization.    Don't inhibit. Don't impede.    Insulate.

⛔️ Don't book in for a body composition scan until you listen to this! Bioelectrical Impedance Analysis (or BIA) scans are popping up in just about every gym and I've even seen some health professional clinics offering them as a service. They're advertised as a quick and affordable way to accurately measure your body composition i.e. how much muscle, fat and bone tissue you're made up of.But if an athlete of mine brings me a scan to interpret, I tell them to throw it in the bin!

It's a specification you see a lot when shopping for preamplifiers and amplifiers for a high end audio system: input and output impedance, expressed in the ohms. Watts are much more easy to understand relating to eventual experience, as well as frequency response bandwidth. But impedance?If you've ever wondered what sonic effect input and output impedance have and what role they play, settle down for this one because Darren explains it all. The discussion of impedance ultimately brings up capacitance in cables, so that's a cherry on top for the cable deniers. But it's all wrapped up in the same concepts, and this one is a can't miss episode for those who want to know more.Earlier in the show, listener questions are answered, covering topics like dynamic range compression and speaker wall construction philosophies.This week's album recommendation is a rare throwback, to a blues master of the 20th century. It's an album that was in Darren's first audiophile library, and which remains a favorite many years on.

We know from physics that everything is energy, and everything is affected by it. Applying this principle to the human body’s inner workings, Billy Holder, a medical technician specializing in bioelectrical impedance technology, uses electrotherapy to help patients recover from various illnesses by reconnecting their circuits. He sees the human body as a repository of past trauma, which translates to somatic experiences for people. Using bioelectrical impedance technology, he helps patients get rid of circuit blockages and restore the body’s connections with itself and with the brain. Working on a technology that has barely seen five years from its inception, Billy is a pioneer in this promising field of energy-based medical technology.

Volume 25 Issue 3, June 2020Dave Pechter discusses with Georges Muller & Yann Barrandon their two featured research articles, "Traceable Impedance-Based Dispensing and Cloning of Living Single Cells" and "Impedance-Based Single-Cell Pipetting."Traceable Impedance-Based Dispensing and Cloning of Living Single Cells: Single-cell cloning is essential in stem cell biology, cancer research, and biotechnology. Regulatory agencies now require an indisputable proof of clonality that current technologies do not readily provide. Here, we report a one-step cloning method using an engineered pipet combined with an impedance-based sensing tip. This technology permits the efficient and traceable isolation of living cells, stem cells, and cancer stem cells that can be individually expanded in culture and transplanted.Impedance-Based Single-Cell Pipetting: Many biological methods are based on single-cell isolation. In single-cell line development, the gold standard involves the dilution of cells by means of a pipet. This process is time-consuming as it is repeated over several weeks to ensure clonality. Here, we report the modeling, designing, and testing of a disposable pipet tip integrating a cell sensor based on the Coulter principle. We investigate, test, and discuss the effects of design parameters on the sensor performances with an analytical model. We also describe a system that enables the dispensing of single cells using an instrumented pipet coupled with the sensing tip. Most importantly, this system allows the recording of an impedance trace to be used as proof of single-cell isolation. We assess the performances of the system with beads and cells. Finally, we show that the electrical detection has no effect on cell viability.

Chris is doing a lot of blocking and tackling, which, it turns out, isn’t about pulleys. For the purposes of this discussion, blocking and tackling means adding telemetry events to elixir projects. Neither Amos or Chris want to be the ones who have to work out these details and would rather play with chatbots. The main topic this week is abstractions. Chris thinks that the same people who misuse phrases like “Impedance mismatch” also misuse terms like “abstraction,” but he also admits that he’s wrong about everything he says. The guys talk about the differences between abstraction and encapsulation. In the end, Chris only wants to write SQL queries and run them. Somehow the conversation devolves into comparisons between type systems. Chris has a moment of self-awareness, then regresses to standing on soapboxes and shaking his fist at the clouds.

This week I talk about impedance in speaker systems and feature the Tejon Street Corner Thieves for our Song of the Week!

This is the audio from our video here: https://youtu.be/pmUq8uK_AL8 Nerd warning! This show is probably not for first-time viewers, nor anyone looking for quick and simple answers. This stuff is deep, fundamental… and yet all grounded (pun entirely intended) in basic electronics! We are delighted to once again welcome Simon Jarrett to the studio. Simon is the man behind Kingsley Amplifiers (and pedals), based in Maple Ridge, Canada. Dan and I have been consistently blown away with Kingsley’s range of pedals and preamps, partly because of their meticulous design and build quality and partly because they are imbued with Simon’s own personal musical connection with tremendous guitar tone. We attempt to unravel some of that in this show, talking about guitar electronics basics such as input impedance, capacitance in guitar controls (low pass filter) and amp/pedal input stages (coupling capacitor/high pass filter), gain stage biasing and all those interrelated factors that have a fundamental effect on your guitar sound… long before you get into to worrying about which of the 487 Tube Screamer clones to buy. It will be well over the heads of anyone looking for quick fixes or simple answers and advice… but absolutely fascinating for anyone who has been playing and tweaking for years and not quite connecting the dots of what’s actually happening (like me, Mick here). Massive thanks to Simon and his wife Christine for taking time out of their vacation to spend time nerding at That Pedal Show. Enjoy the episode. If you dare!

Episode 35: Impedance of God's Assignment by Sam Olagun-Samuel

Resistance is a very important element of an electrical circuit. As electricians we use the term impedance more than we use resistance, as impedance refers to AC circuits – whereas resistance refers to DC. Resistance and Impedance are both methods of slowing down current enough for it to be usable. When current is unimpeded (meaning… Continue reading What is Resistance/Impedance (Ohms) – Why electricians need to know it

Resistance is one of the most crucial aspects of an electrical circuit.  Along with Voltage and Amperes, Resistance plays a major role in how a circuit operates.

Today I’m off to a sports nutrition store near where I live called Complete Nutrition. In talking with some fellow “losers” at work I found out they can provide a body composition report. The report give weight of fat, water, and muscle/skeletal tissue, BMI, body fat and muscle by percentage of total weight, and, weirdly, the weight of various body parts.

When I sent out the newsletter announcing the last "Explain Like I'm 5 Podcast," I asked which audio topics you wanted to hear explained to a 5-year-old. As as result I now have a list of over 25 topics for future shows! But the response I got the most was "impedance." One reader even taunted me: "Haha, explain impedance like I'm five..good luck with that ;)" Challenge accepted, buddy! Impedance is one of those audio concepts that comes up at almost every recording session or live sound gig, even if you're not aware of it. Grasping the basics of input and output impedance can make you aware of potential problems before they happen, and help you problem solve more quickly and confidently. And the truth is that the fundamentals of impedance are simple enough that you can learn them from a 15-minute podcast. In today's ELI5 podcast, I begin with a discussion of acoustics before moving to electronics to show you that you already know more about impedance than you probably think. I go on to cover exactly what input/output impedance specs mean, illustrate the concept of impedance with examples from the studio, and explain what impedance mis-matches can do to your sound. Download the mp3 or subscribe via iTunes. Subscribe to the DIYRE podcast Do you understand impedance now? How easy was the podcast to understand? Is there any other topic you'd like to hear explained as if to a 5-year-old? I welcome your feedback in the comments.

Foundations of Amateur Radio When you use your trusty multi-meter to measure resistance across a 50 Ohm resistor, it shows 50 Ohm, but when you use it across a piece of 50 Ohm coax, you see either infinity, or 0. Similarly, when you measure across a folded-dipole, you see 0, not 300 Ohm. Does this mean that a 50 Ohm resistor is somehow different than a 50 Ohm piece of coax and why is the feed-point impedance of a folded dipole 300 Ohm, when your multi-meter clearly says it's 0? Does this mean that there are two types of Ohm? Today I'm going to explain why this is and what's going on. Yesterday I started reading up on the subject and every single explanation I came across went into deep ju-ju with scary maths, using complex and imaginary numbers. I did a bit of that in my dark past, but none of that is needed to understand what's happening. As you know, there is such a thing as Direct Current or DC - we use it with batteries and little power supplies, in simple circuits and all manner of day-to-day activities. There is another world that we as amateurs use, the world of Alternating Current or AC. In house-hold wiring we use 50 or 60 Hertz and different voltages depending on where on the globe we are. In radio terms we use it for our transmissions, on HF at several Mega Hertz and beyond. These two different worlds, the DC and AC world don't appear to have anything in common. Here's the kicker though, they are the same thing. Yup. DC and AC are the same thing. What? Yup. I'm not making this up. As you might recall, if you look at an AC voltage, it goes from plus to minus and back again. A 50 Hertz alternating current does this swap 50 times per second. When you're rag-chewing on 40m, or 7 MHz, it happens 7 million times a second. From plus to minus and back, 7 million times. Clearly there has to be some impact on this massive level of activity. Think of direct current as an alternating current with a frequency of 0 Hertz, that is, over time, DC doesn't change. So, DC is a short cut for saying AC at 0 Hertz. If you understand that explanation, then some really cool stuff starts to happen. Before I get to the cool stuff, you might recall Ohm's Law, commonly expressed as: "Given a current and a resistance, we can determine a voltage". Said in another way, the resistance of a circuit is related to the voltage and the current in the circuit. Now, in this simple form of Ohm's Law, the voltage doesn't change from plus to minus and back again. That is, over time, there is no change. Now if you start doing funky stuff with your voltage, like change it from plus to minus and back again, an additional type of resistance comes into play, called reactance. This reactance is the part that is affected by voltage change over time. So if you swap the voltage from plus to minus and back again a million times a second, the reactance has a big part to play. In short, there are two types of resistance, one that is independent of time, called resistance, and one that's dependent on time, called reactance. Both of these, resistance and reactance, happen within a circuit. If the voltage doesn't change over time, then the reactance part is zero and similarly there are circumstances where you can have a resistance of zero but have a reactance that's not - one example is a folded dipole. Now, if you combine the resistance and reactance, you get something called impedance. Now you have all the bits. Resistance is expressed in Ohm, Impedance is expressed in Ohm, and thus Reactance is also expressed in Ohm. If we look at our folded dipole with a feed-point impedance of 300 Ohm, you now know that this 300 Ohm comes from a resistance of 0 Ohm and a reactance of 300 Ohm at the resonant frequency, which is why your trusty multi-meter shows it as 0, since the voltage it uses to measure is alternating at 0 Hertz, which is not the resonant frequency of this antenna. Before I go, the rabbit hole goes deeper. Reactance itself is made up of Capacitance and Inductance, which each deal with the reactance in a capacitor and an inductor, but I'll leave that for another day. So, next time someone tells you that the feed-point impedance of your folded dipole is 300 Ohm, you'll now understand why your multi-meter says it's 0. I'm Onno VK6FLAB.

Is there a role for the Impedance Threshold Device in hypotensive, spontaneously breathing, trauma patients?

In recent years, elastic inversion and quantitative interpretation of pre-stack seismic data have become standard procedures in the petroleum industry. In this presentation, Per Avseth (Norwegian University of Science and Technology) compares extended elastic impedance trends at different chi angles, with rock physics template models. He demonstrates that the elastic impedance attribute does not always comply with the complexity and non-linearity of rock physics models related to geological processes. He also shows how one can honour the non-linearity of a rock physics model and create pseudo-elastic impedance as a function of deviation away from a curved water-wet rock physics model itself (CPEI). Finally, Per demonstrates the use of this approach on seismic inversion data from a selected area in the Mid Norwegian Sea, by mapping of lithology and fluid anomalies that are consistent with rigorous rock physics models.

The impedance threshold device (ITD) is a device used to enhance circulation during cardiopulmonary resuscitation (CPR). This device works by regulating the influx of gases into the chest during the chest wall recoil phase. In this podcast, VetGirl discusses the ITD and how it affects the outcome of patients with hemorrhagic shock.

We look at a numerical example for an RLC circuit and calculate the complex impedance and phase difference.

We continue investigation of the RLC circuit, introducing complex versions of voltage and current. The complex impedance results naturally from these quantities and gives a clear picture of why the current and voltage differ by a phase, and by how much.

We investigate the RLC circuit and obtain a relation between voltage and current without use of complex quantities. We see that the relation is rather cumbersome and not transparent.

Objective: The distribution of ventilation within the lung is inhomogeneous. We hypothesized that the degree of inhomogeneity in patients with cystic fibrosis (CF) differs from that in healthy subjects. Method: Three adult patients with cystic fibrosis (CF) and two healthy subjects were recruited for this preliminary study. Subjects were asked to breathe in as deep and exhale as hard as possible three times. Electrical impedance tomography (EIT) measurements were performed during spirometry tests. The global inhomogeneity index(GI) was applied to assess the degree of ventilation homogeneity at 25%, 50%, 75% and 100% of maximum inspiratory volume. Results: Airway obstruction was detected in CF patients but not in healthy volunteers during spirometry tests. GI decreased as inspiratory volume increased in CF patients (0.59+/-0.20 at 25% and 0.39+/-0.09 at 100%, p

My only issue with it seems to be the increased risk of injury...especially with running. How would you suggest keeping the risk of injury low while still going hard? Scott asks: Have you heard of Whole Body Vibration? Thoughts? Is it safe? Chuck asks: Last week I had an impedance test done. I'm sure you know what it is, but they connect electric pads to you ankle and wrist and an electric current is sent between. Based on the time it takes, it measures your body fat, water, cell health, and water in your cells. The problem is, I don't recall what each of these measure, but for someone in great shape and very healthy, some of my ranges we low? Can you talk a little about this and why I may be low? Here were my results: Body fat: 2.9% Resistance: 404.0 ohms Reactance (Xc): 37.8 (I don't have the ranges, but I think this was one of the level she told me was low) Impedance (Z): 406.7 (Impedance (symbol Z) is a measure of the overall opposition of a circuit to current, in other words: how much the circuit impedes the flow of current. It is like resistance, but it also takes into account the effects of capacitance and inductance. Impedance is measured in ohms, symbol) Phase Angle (like overall health of cell): 5.3 degrees. This was low- which is weird--why? Lance Armstrong's is about 12.0 Craig asks: I have found ice baths after a run work for me. However, when it is really hot outside I have trouble getting them cold enough (54-59 degrees). What I do now is run the water and then put 8 trays of ice plus all the ice my ice-maker has made since my last run in the tub. This doesn't get it cold enough. I know that I could buy a bag of ice from the grocery store but this is not very convenient. On the other hand, do you know of something I could buy that would be something I could just keep on hand? In my response to Craig, I mention this Blitz 110% post. Matthew asks: Is there any natural glycolic acid or AHA peels you recommend for mildly acne prone skin? I took your recommendation to eat sardines and I feel that this is helping my skin, but I still could use a good method to help remove dead skin from my sensitive face. Peter asks: Looking for your thoughts on S.A.D. seasonal affective disorder, winter blues, weight gain around holidays, etc... Laura asks: Have you heard of the ARP wave clinic? I have arthritis in my knee and was considering this therapy after exhausting many modalities up to this point. What are your thoughts? David asks: A company named JD Premium has put out a product names Adapt Energy that can be added to water or taken directly to help with energy and concentration. I have heard you talk about the advantages of some adaptogens in past podcasts. Based on the products contents, are these adaptogens? Are the ingredients harmful in any way? In my response to David, I mention this podcast with Roger Drummer. Shawn has a call-in question about cyclocross and how to increase his ability to move up to the next level. Robert asks: I have what I call "congenital inflexibility" I've now been into triathlons for about 2 years, becoming an endurance athlete for the first time in my life, and I'm really enjoying it. However, I do feel that my speed gains are being greatly limited by my inflexibility. For instance, in the swim I cannot stretch my arms straight past my ears. In the bike I am limited in my aero position, etc. I do some limited before and after stretching now, but I also know there are very mixed results in studies in whether stretching before or after exercise is actually helpful (at least in preventing injuries). In addition, I feel that whenever I spend too much effort stretching, attempt yoga, etc I am twice as likely to hurt myself. I am really worried that my inflexibility is going to hold me back, particularly in the swim. Do you think it's possible for someone who is totally inflexible to ever become reasonably flexible? In my response to Robert, I mention Resistance Stretching with Dara Torres. Brock asks: I get quite a lot of bloating and gas about an hour after I do a long or intense swim workout. I assume it is from gulping in too much air while I swim. Is there anyway to work on eliminating this issue? Are there any drills you can recommend that could help with this. It uncomfortable for me... and everyone around me. John asks: I swam 40 X 50 yard laps in an outdoor heated pool today and threw up. I had a piece of toast 1/2 hour before swimming, felt fine. I did not swallow a significant amount of chlorinated water during the swim. I was feeling fit and fine before and during the swim. Any comments? Jon asks: The other day I did some hard 800 meter repeats and I had some foamy sweat below the waist. Have you ever heard of this and what is it? -------------------------------------------- Remember, if you have any trouble listening, downloading, or transferring to your mp3 player just e-mail ben@bengreenfieldfitness.com And don't forget to leave the podcast a ranking in iTunes - it only takes 2 minutes of your time and helps grow our healthy community!
