True Flexibility

True Flexibility

by Cat Fitzgerald


Did you know:

“We are supposed to peak athletically between the ages of 35-45; not in our teens.”

“True flexibility is cumulative and permanent.”

You should be a little perplexed, maybe even a little peeved, but interested – dubious, yet hopeful. When I picked up Bob Cooley’s The Genius of Flexibility for the very first time and read these two statements, a few things cascaded like Pachinko balls in my head: “Nobody I know thinks they are as flexible, or more so, now, than when they were younger,”  “This isn’t what I witness in everyday life nor experience myself,” and “If this is true, I have to know what [Bob Cooley] knows.”

Not to burst any bubbles out there, but, the memories of our flexible youth, of splits three ways, contorting to fit into luggage bags (if you had an older brother like mine), and back bends around beach balls and telephone poles, are lies. More accurately, they are misconceptions.

We all have photos of those magic tricks proving that we could wrap our ankles behind our necks; it just wasn’t flexibility that allowed us to perform all of those nimble feats. It was hyper mobility of our joints and soft tissues – the very things that allowed us to bend, bounce back from injury, and sometimes bounce back uninjured from that which should have been devastating. The irony is that we feel like we are missing now what we didn’t actually have back then.

The good news is that we CAN have it today. We can have now what we never had, even though it feels so very unattainable. It just takes a bit of work.

Settling on Terminology

Long muscles are not automatically flexible ones, and short muscles aren’t necessarily tight. We tend to confuse Range of Motion (ROM) and Flexibility with our ability to get a task accomplished. Every person to whom I say, “You have inflexible hamstrings,” as they stand before me, straight legged with their palms firmly planted on the ground, gets upset with me, to say the least. Sure they may have long hamstrings, but, when the muscles ability to contract reciprocally is not present, there is a problem.

Flexibility is a muscles ability to lengthen and to shorten. There is a clear distinction between “shorten” and “contract.” We can contract and shorten – Concentric Motion, or contract and lengthen – Eccentric Motion. ROM is just what it seems: the distance and direction a joint can move between the flexed position and the extended position without the benefit of substitution or recruitment of other bones, joints, or muscles, and it is easy to measure. Here’s a quick exercise:

Stand in front of a mirror and lift your straightened arm until it is pointing to the ceiling. Take note of the relationship between your arm and your head. How far apart are they? Which direction is your elbow pointing? Now, look at your shoulder. Has the distance between your neck/ ear and shoulder changed?

Now do it again, but stop as soon as you see your shoulder elevate, making the space between your shoulder and neck or ear smaller. This is a more accurate picture of your actual Range of Motion.  Next time I will give you the keys to increase your ROM and get you started on your path to a healthier, more resilient, more flexible body.

Be.

Heartburn

Heartburn

by Dan Silveira


I have been diving for 19 years, and I am happy to say that for the most part, I've never had severe heartburn on a dive until recently. I was coming up from a dive when suddenly a sharp burning pain occurred in my esophagus. It felt like someone was pouring hot tea down my throat. I continued to dive and the symptoms escalated and got worse. It got to the point that the pain was debilitating, and forced me to stop diving for the day. I quickly realized that I needed to learn about my problem in hopes to find a solution. I don’t ever want to experience heartburn while diving again!

 

From the info that I dug up, it seemed like there could be multiple contributing factors to heartburn.

1. Foods and drinks that cause you to produce more stomach acid:

GERD Diet – Good Foods for Heartburn – Bad Foods for Heartburn ...

2. Immersion causes Increased pressure on stomach and can distort the stomach-esophagus valve so that it leaks more easily.

3. A tight wetsuit or a tight weight belt around your stomach can also increase pressure on your stomach, and might be a small factor.

4. When you are inverted gravity will increase any stomach acid leakage into the esophagus if the stomach-esophagus valve is not well sealed.

5. I think that some people have damaged or defective stomach-esophagus valves or other medical issues that require surgery or special medications or treatment from a doctor (see the links below about treatments).

For prevention, there are few kinds of medicine.  Some help reduce neutralize acid in your stomach.  Others help to decrease the amount of stomach acid your body produces. There are over the counter medicines and more powerful prescription ones you can get if you see a doctor.  There are also surgical options.  Here are some pretty good descriptions of the options:

Heartburn Treatments: OTC and Prescription Medications

The approach I am going to try for dive trips is to be more careful about what I eat, and take a Pepcid Complete (over the counter medicine that both neutralizes acid and decreases acid production), 1 every 12 hours.  If I still get heartburn, I'll use some liquid Mylanta medicine to help relieve the symptoms.  It also contains antacids to help neutralizes acid in the stomach, and I think that it coats your esophagus and stomach to reduce irritation from the acid.  I haven't really had a chance to try it out since I haven't done any trips since I got the new info.

As you can see from this link, Terry Maas wrote about heartburn in the physiology chapter of his freedive book.  The info on the link is limited, but the book has much more details about the issue.

You may want to double check facts of these statements or consult with a doctor before using any of the information listed above. The info I have gathered was through the help of my friends Tom Fiene and Paul Young who started experiencing heartburn before I did. They had done much of the research, and when I finally experienced the same heartburn problems, I asked them for the info they had already dug up.

As of now, I have not had any reoccurring issues with heartburn.

 

Here is what I did:

  1. Watch my diet. – NO GREASY OR SPICY FOODS a few days prior to diving!
  2. Eat less food before diving or no food is possible.
  3. Take two Tums the night before diving when in doubt.
  4. Stay away from foods that cause lots of gas.
  5. Drink Insure Plus for quick energy while diving – 300+ calories in a liquid form that tastes like vanilla!
  6. Take off my weight belt when I am in my kayak or on the boat.
  7. Use a proper fitting freedive wetsuit.

Yours,

Dan Silveira

Freediving and Recreational Diving Industry

by Mark Wallerstein


In the United States, freediving is growing exponentially in popularity and thousands of persons are taking up the sport each year.  Only a few years ago, a freediver would have to travel long distances or order online to find the right gear. Now, it is becoming more and more typical that a person can walk into a scuba store and there will be an entire section devoted to freediving or spear-fishing gear. In the younger generation freediving, unlike scuba, is still looked upon as somewhat of an extreme water sport; which drives in even more people.

Like scuba, freediving is a self governed sport. However, scuba and freediving do have their differences.  For scuba, a person needs a certification card to rent gear, fill tanks, or go on dive charters. For freediving, on the other hand, any person can buy a pair of long fins and head for the ocean without a second thought from anybody, training or not.  As of now, freediving is primarily taught by friends or family members, which could potentially lead to major problems for the industry in the near future.  It is only logical that as more people take part in the activity, injury numbers will grow.  This will have a serious adverse impact on those of us professionally involved in freediving.

Freediving Courses with FII (Freediving Instructors International) www.freedivinginstructors.comAgencies should continue to be able to teach what they like, but certain standards should be met by all. With this growth in the industry, freedivers will be booking trips on scuba charters to dive new waters. Without a certification card from a known and insured agency, a divemaster has no way of knowing what training, if any, the person has had.  An untrained group can easily board a boat for freediving, injure themselves, and jeopardize the charter company and the on-board divemaster and crew. It may be early and asking a lot to have every freediver go to school for a C card, especially for people that have been doing it for years. However, it is not too much to make it mandatory for groups going out to have at least one freediver who has been trained in safety by a certified instructor.

It is also not solely the responsibility of the diving party itself. The working divemaster should have training or at least knowledge of freediving safety so that they can recognize problems and act accordingly. The industry should have set safety standards and procedures for all patrons. Safety procedures should not be something taught by a friend based upon personal experience. There needs to be set procedures and actions that are familiar to all while at the same time insuring the safety for all.

Establishing uniform standards is not only a good thing for people’s safety, but for the industry as a whole. With uniform safety standards, more insurance companies will be willing to insure agencies and instructors. Dive charters will start feeling better about bringing freedivers out and be able to cater to an entire new market. People will need to take classes, which scuba stores can offer. Overall, it will bring money back into an industry that has been suffering lately. Overall and beyond anything else, it can save lives.
