Fw: DrMirkin's eZine: Bicycle seats, blood sugar/blood fat, more . . .

April 5, 2012

I have listened to all 250 radio shows this man had back in the late 90's

and up to 2003 when he retired. lots of good things to know if you go back

and listen to the radio shows that you can find on his web site.

DrMirkin's eZine: Bicycle seats, blood sugar/blood fat, more . . .

> Bicycle Seats and Numbness in Male and Female Cyclists

>

> Several studies have shown that male bicycle riders can

> become impotent from pressing their genitals against a bicycle

> seat. A study from Yale showed that compression from a bicycle

> seat can cause loss of feeling in a woman's genitals (J Sex Med

> 2006;3:1018-1027). Now, a new study from Yale shows that the lower

> a woman sets her handlebars, the more she bends forward and the

> harder she presses her genitals against the bicycle seat to cause

> this loss of genital feeling (J Sex Med, published online March 5,

> 2012).

> Women who suffer the most genital numbness set their

> handlebars below the height of their seats. Riders set their

> handlebars low to lower their bodies so they can go faster. More

> than 60 percent of the force you press on your pedals is lost by

> the air resistance against you and your bike. So, to go faster,

> you make yourself lower and narrower.

> Most bicycle seats have a round back portion to support

> your buttocks and a narrow nose in the front. While genital

> discomfort during long rides is very common among bicycle riders,

> it is uncommon in professional bicycle racers. Experienced

> bicycle racers know how to choose and adjust their seats to

> prevent discomfort when they ride. They usually:

> * set the nose level with, or slightly higher than, the back

> of the seat,

> * adjust the height of their seat post so that they never

> straighten their knees during pedaling, and

> * chose a seat with just enough padding to prevent discomfort and

> width to support their buttocks.

> Noseless bicycle seats cause little or no genital

> discomfort, but racers cannot use noseless seats because they need

> to press on the nose with their inner thighs to control the bike.

> A noseless seat also forces riders to increase pressure on the

> handlebars, increasing their susceptibility to hand numbness.

> IMPOTENCE: Impotence is most commonly caused by nerve or

> artery damage. Exercising regularly helps to keep arteries healthy,

> so bicycling helps to prevent impotence, as long as it does not

> damage the local arteries and nerves. Three percent of regular male

> bicycle riders become impotent, and virtually all of them felt pain

> or numbness before the problem occurred. When a nerve is pinched or

> the blood supply to the penis is shut off, a man feels numb. Men

> who ride with conventional bicycle seats and do not feel numb are

> not likely to be at risk for impotence. If you feel no discomfort

> when you ride, keep on riding.

> Half of the penis is inside the body and the main blood

> supply comes from the area just behind the scrotum and in front of

> the rectum. So bicycle seats that press on that area can cause

> impotence, while those that do not have a nose and have a widened

> area to hold your weight on your sitz bones should prevent the

> problem. Some seats have holes in the middle; the theory is that

> if there is no pressure behind the scrotum, there will be no

> numbness.

> TIPS TO PREVENT DISCOMFORT FROM A BICYCLE SEAT:

> 1) Avoid seats with excessive padding. The greater the padding,

> the deeper you sink into the saddle and the more likely you are to

> feel numbness.

> 2) Use a gel saddle that is not too hard and not too soft.

> 3) Do not tilt the saddle nose downward. The seat should be level

> or angled slightly upward.

> 4) Set your handlebars higher to reduce how much you bend forward.

> The lower you bend, the greater the pressure on your perineum.

> However, sitting upright increases wind resistance and will slow

> you down.

> 5) Change positions and stand often while you ride.

> 7) Wear thin padding in your pants. Most good bicycle pants come

> with form-fitted chamois padding.

> High Rises in Blood Sugar or Blood Fat Shorten Life

>

> High rises in blood sugar or blood fat levels increase

> risk for cell damage, heart attacks, strokes, and premature death.

> Blood sugar levels are most likely to rise too high after taking

> sugared drinks or sugar-added foods (except during exercise), and

> blood fat levels rise very high after eating a high-fat meal.

> EXERCISE HELPS TO PROLONG LIFE AND PREVENT DISEASE:

> Exercising, before, during or immediately after eating helps to

> prevent these high rises in blood sugar and fat levels. High-

> intensity exercise is far more effective than less-intense

> exercise in preventing high rises in blood fat levels after a

> high-fat meal (Clinical Science, March 2012). Nine men

> participated in the following study:

> Day 1: Subjects rested (Control Group), walked briskly for 30

> minutes (Walking Group) or performed 5 repeats of 30-second all-

> out sprints (High Intensity Group).

> Day 2: Subjects ate a high-fat meal for breakfast and for lunch

> three hours later.

> Only the high intensity exercisers had a marked lowering of

> their rise in blood fats, and a lowering of their production of

> oxidants after a meal. Oxidants damage arteries and other

> tissues.

> POINTS TO REMEMBER:

> 1) Most cases of disability and premature death in America today

> are caused by lack of exercise and eating too much food, sugared

> foods and high-fat foods.

> 2) A high rise in blood sugar or blood fat after meals is one of

> the causes of premature death.

> 3) Exercising helps to prevent premature death by reducing and

> preventing this high rise in blood sugar and blood fat after meals

> 4) Intense exercise is more effective than just exercising in

> preventing a high rise in blood sugar and blood fat after meals.

> 5) The foods that cause the highest rise in blood sugar and fats

> are sugared drinks, sugar-added foods, and foods loaded with

> animal fats in their meat and dairy products.

> Exercisers Should Not Take Sugared Drinks an Hour before a

> Hard Workout or Competition

>

> When you take sugared drinks when you are not exercising,

> * your BLOOD SUGAR LEVEL RISES. If it rises too high, sugar sticks

> to the outer surface of cell membranes and damages these cells.

> * To prevent sugar levels from rising too high, your pancreas

> releases large amounts of INSULIN to drive the sugar from the

> bloodstream into cells. High levels of insulin constrict arteries

> leading to your heart to increase risk for heart attacks. High

> levels of insulin also convert sugar to fatty triglycerides and

> high levels of TRIGLYCERIDES increase risk for clotting, heart

> attacks, obesity and diabetes.

> * HDL chholesterol is used to carry triglycerides from your

> bloodstream to your liver, so you LOWER BLOOD LEVELS OF YOUR GOOD

> HDL CHOLESTEROL.

> * The extra triglycerides in your liver lead to a FATTY LIVER that

> can cause DIABETES.

> WHY IT IS SAFE TO TAKE SUGARED DRINKS WHEN YOU EXERCISE:

> Blood sugar levels do not rise too high during exercise because

> your exercising muscles can remove sugar from the bloodstream

> without needing insulin, so the damaging events described above do

> not occur.

> WHY IT IS UNWISE TO TAKE SUGARED DRINKS ONE HOUR BEFORE

> EXERCISE: Your blood sugar level can rise too high. This causes

> your pancreas to release huge amounts of insulin. Then when you

> start to exercise, your blood sugar can drop too low, forcing you

> to slow down or even causing you to pass out, because:

> * high insulin levels drive sugar out of the bloodstream into

> cells, and

> * muscles that are being contracted pull sugar out of the

> bloodstream.

> WHY DO YOU NOT SUFFER A LOW BLOOD SUGAR RESPONSE WHEN YOU

> TAKE SUGARED DRINKS DURING EXERCISE OR IMMEDIATELY BEFORE YOU

> BEGIN: Once you start moving, your body produces large amounts of

> adrenalin and nor adrenalin that prevent your pancreas from releasing

> large amounts of insulin, and your blood sugar level does not drop

> (Science 1966; 152: 1248-1250). Taking sugared drinks during

> prolonged exercise can provide the sugar and fluid you need to

> maintain intensity (Eur. J. Appl. Physiol. 1995; 70: 54-160).

I didn't know he died. I used to hear him on our CBS radio station, WWJ in

Detroit.

Maybe I will go check into his web site.

April 5, 2012

I didn't say he died yet. last I knew he and his wife were still racing bikes

on the weekends in and around New York where he lives now. I still get his email

every week.
