Health must be Earned and Learned

Posted on by

The after 50 set back that occurs in many people is due to improper diet. Once you past the age of 50, you must begin to rebuild your body — if you wish to avoid senility and retain sound mentality and physical vigor. As long as you supply the body with the materials it needs to rebuilt and repair cells you will have good health.

Re-examine your dietary habits — make sure your daily intake of food is nutritional. Slowly eliminate processed food (which is white flour and their products, french fries, cake, cookies etc.) and sugar from your eating habits. Now, you might say what’s left? There are many natural foods that are super in nutritional value and will do wonders for your muscle size and overall shape. It’s time you began to build a knowledge and understanding for good nutrition while you build your body. Be aware of the vitamins, minerals in food and what fantastic things these foods can do for you and your body.

Protein is the bodybuilding substance needed to form new tissues and cells and rebuild and repair old one. Your blood, tissues, organs, skin, hair, and nails are about 95% protein, along with your bones and nerves. Meat, fish, eggs and poultry are known as complete proteins. Others include soybeans, sunflower seeds, and peanuts. 60% of protein consumed is changed into sugar (glucose), that’s why sugar is completely unnecessary in your bodybuilding diet.

2/3 of your diet should be protein — the other third should be made up of fresh raw fruit, vegetables, nuts and seeds. Liver is the most effective source of complete protein. It’s the number on food that not only builds your body up, but greatly increases your energy. It relieves fatigue and neutralizes many dangerous drugs within your system.

Fat produces an energy reserve, slows down the rate at which food is digested and is a source of heat and energy, and a cushion for vital organs. Fish is practically a perfect food. It’s excellent source of high quality protein, vitamins and minerals. Eggs, are another superior protein food, 1-2 a day are recommended for everyone. They supply a full measure of minerals. True, they do contain cholesterol, but they are an excellent source of lecithin, inositol and many other effective cholesterol controlling agents. Powdered milk is outstanding because it consist of an abundance of fat free protein, vitamins and minerals. It’s known to rejuvenate the heart, brain, and verves and strengthens the failing body.

Natural carbohydrates invigorates the body and supplies is with warmth and vitality. The potato is not to be eliminated from your bodybuilding diet. It’s a vegetable and contains many nutritional elements and it’s very easily digestible. Honey is in the blood stream 20 minutes after eaten. It’s the best heart stimulant you can use. Honey has much greater advantage over sugar. It fills any void that may occur in the daily intake.

Here are the 4 fine qualities of honey:

a wholesome food

it’s a purifying cleanser

it has regenerative power

it’s a sweet that has natural laxative qualities

REMEMBER: It is not how much you eat — it’s what happens to the food after you have eaten it. Eating large quantities of food will not help your muscle building progress it it’s the wrong food!!

All Abdominal Exercises are Not Created Equal

Posted on by

by J. R. McNeal, M. S., C.S.C.S. and W.A. Sands, Ph.D.

The fitness industry is replete with exercise devices designed to enhance fitness or sculpt the body. They are marketed to the unsuspecting and often gullible consumer, promising quick fixes and effortless results. Oh, if only it was that easy! Considering the amount of money Americans spend on fitness gadgets, we should be the fittest nation in the world instead of the fattest! One of the most recent trends in the industry is the emergence of the various abdominal conditioning devices, designed to “isolate” the abdominals (as if that were possible!), reduce neck strain, and in general make exercising the abdominal muscles an enjoyable experience. Are all of these devices created equal? How do they compare to a regular crunch, or the “forbidden” situp? The purpose of our investigation was to answer these questions. We decided to compare 6 different commonly performed exercises and devices to see if indeed there are differences in muscle activation and range of motion. By comparing the amount of muscle activation achieved, we can make recommendations regarding the relative value of one exercise over another with respect to force generated by the target muscles (the abs). Range of motion meanwhile, is a variable that has been virtually ignored in the fitness research literature. Watch virtually any throwing activity for example, and you can see that the range of motion of the trunk during such movements is large indeed.

We asked 20 active, college-aged students to participate in this investigation (10 females, 10 males). The exercises selected were 1) a regular crunch from the floor, 2) a regular situp with feet constrained, 3) a situp with the addition of the AbMat™ pad, 4) a crunch performed with an ab-roller type device, according to the recommendations of the manufacturer, 5) a crunch performed with the ab-roller combined with the AbMat™ pad, and finally 6) trunk flexion utilizing the Ab Bench resistive device. The exercises were demonstrated to the subjects, and they were allowed to practice each until they were comfortable with their performance. They were then videotaped with high-speed video while performing 3 trials of each exercise. Various anatomical structures of the subject were marked with reflective tape so that they were evident on the screen. This allowed the videotaped performances to be digitized and analyzed for specific kinematic information; in this case, angular displacement. Electromyography electrodes were placed on the upper and lower abdominals to assess muscle activity.

Findings:
For the lower trunk angle, the AbMat™ and Ab Bench achieved significantly greater ranges of motion than did the ab-roller exercises, the situp, or the regular crunch, although the traditional situp was significantly better than the ab-roller exercises and the regular crunch. At the hip and upper trunk angles it was again discovered that the AbMat™, Ab Bench, and the traditional situp were better than the ab-roller devices or the regular crunch at moving through a large range of motion. In most cases, the ab-roller exercises and the regular crunch did not differ from eachother, making the purchase of an ab-roller for specifically conditioning the abdominals questionable when compared to the regular crunch, which doesn’t cost anything! However, if the goal is exceptional conditioning of the abdominals through a large (“functional”) range of movement, then devices such as the AbMat™ and Ab Bench, which place the abdominal muscles in a slightly stretched position prior to each repetition, may be a wise equipment investment.

The muscle electrical activity provided even more insight into the efficacy of these particular exercises. It was of particular interest to us that the recordings from the abdominals could be described by different characteristic recordings; the regular crunch, ab-roller exercises, and the AbMat™ were characterized by a continuous activation pattern with a low amplitude (low force output), while the Ab Bench and situp were described by two distinct phases, concentric and eccentric which were of much higher amplitude. We did not feel we could adequately compare the two groups of exercises against each other due to these differences and thus the results basically compare exercises within each group. This is one example of the problems that can influence the results of electromyography studies of the abdominals, and any study not accounting for these differences should be considered with some reservation. Another problem which is inherent in electromyography investigations of the abdominals (but rarely if ever acknowledged by researchers in their results!) is the problem of skin and fat rolling that occurs whenever the trunk flexes. This makes the nature of the muscle electrical activity change as the electrode moves farther from and closer to the muscle. We feel that it is important to be aware of such shortcomings in this type of research so that you can become a more knowledgeable consumer.

The continuous activation exercises were not different in their activation of the upper abdominals. However, for the lower abdominals the AbMat™ elicited significantly more activity than did the ab-roller exercises. The regular crunch was superior only to the ab-roller exercise used simultaneously with the AbMat™. Therefore, the AbMat™ seems to be the superior exercise of this group for eliciting muscle activation, especially when the lower abdominals are considered.

The situp and Ab Bench exercises as stated earlier, were different in their EMG patterns. Because the EMG was greater in these exercises, but occurred over a shorter time period, these exercises may be better choices if large force production is desired, rather than muscular endurance. For both the upper and lower abdominals the situp produced greater activation than the Ab Bench. It is critical to note, however, that due to the limitations of this study and these typical subjects, we were not able to approach any kind of maximal load on the Ab Bench. The Ab Bench allows resistance to be added to the exercise, which would cause an increase in muscle activation to move the increased load. In other words, one should be able to get any level of activation up to a maximum with the Ab Bench. The situp is constrained by the weight of the individual’s upper body. This was likely a major drawback in the ability of this study to properly distinguish between these two exercises. Common sense would tell us that if we were able to increase the resistance provided by the Ab Bench, the muscle activation results would have been different.

In conclusion, it can be recommended that ab-roller devices may not be any better than the regular crunch in conditioning the abdominals. For specificity of movement, equipment such as the AbMat™ and Ab Bench which place the spine in a slightly hyperextended position prior to abdominal contraction may be better choices, especially for sport performance. The situp appears to also be a good choice for both range of motion and activation, although it is limited in the amount of resistance and thus less muscle activation which can be achieved

Upper and Lower ABS

Posted on by

by Dr M. C. Siff

Introductory Note
For newcomers, these P&Ps are Propositions, not facts or dogmatic proclamations. They are intended to stimulate interaction among users working in different fields, to re-examine traditional concepts, foster distance education, question our beliefs and suggest new lines of research or approaches to training. We look forward to responses from anyone who has views or relevant information on the topics.

Puzzle & Paradox 92
The debate about whether or not it is possible to separately exercise the upper and lower abdominal erector muscles may not have been definitively settled yet.

There is still considerable debate about whether or not it is possible to exercise separately the upper and lower portions of the recti abdominis muscles, especially since the recti constitute a single band of muscle between origin and insertion. Numerous books and fitness professionals refer to crunches and situps for the ‘upper abs’ (with the pivot being the distal rectus attachment on the pelvis), and pelvic curl or leg pushes into the air for the ‘lower abs’ (with the pivot being the proximal rectus attachment on the lowest ribs and spine).

EMG studies show that both the ‘upper’ and ‘lower’ abs show considerable electrical activity during both of these types of exercise, so that some authorities dismiss the idea of separate isolation exercise of the upper and lower abs.

Yet, a TV programme some years ago showed a belly dancer using her highly skilled abdominal musculature to roll a few quarters (US 25c pieces) up, down, diagonally and sideways across the belly. She concluded her unusual display by successfully folding a dollar bill placed on her belly. From this vaudeville display, it would certainly appear that it is possible to activate different parts of the abdominal musculature in skilled sequences. This might then suggest to the skeptic that it may be meaningful to talk about separate exercise of the upper and lower regions of the abs.

Of course, we must note that the effectiveness of most non-explosive exercises depends primarily on the amount of concentrated focus and voluntarily produced goal-directed muscle tension, so that one’s visualization of the exercise would appear to have a profound effect on the pattern of activation of any muscle. This also depends on the patterns of breathing and breath-cessation used during the exercise.

Some authorities state that, since the different regions of the abdominals are separately innervated, one should certainly be able to activate upper and lower regions of the abs separately.

However, in saying that the lower abs are separately innervated we have to be cautious in misapplying this information. All of the rectus abdominis and the obliques are innervated by branches of the thoracic nerves T6 or T7 – T12, as is transversus (by the ventral rami and L1). This would tend to imply that the lower abs and lower obliques(?!) should be activated by stimulation of T6/7 – T8/9 and the upper abs and upper obliques (if these exist!) by the remaining thoracic nerves. In addition, an examination of their nervous innervation would also suggest that there should be separate activation of upper and lower transversus.

This clearly confounds the entire issue of trunk action and situps for the supposedly different parts of the trunk muscles. We can only resolve the issue if we stop talking about upper and lower abs etc and analyze in terms of a graduated activation of all of the trunk muscles progressing from the extreme top to the extreme bottom (as defined by the appropriate nerves) – much in the way that a caterpillar moves.

This would appear to offer a far more accurate and logical biomechanical approach, since the current view of upper vs lower abs would imply that there should be a somewhat jerky discontinuity somewhere during a full crunch. The entire action of trunk flexion is smooth, well-controlled and continuous, so this observation supports my view that there is a smooth continuum of activation of the entire abdominal (and erector spinae) group.

If one wishes to simplify, then it would be crudely accurate to talk of upper, mid and lower abs, but this still tends to mask the fact that there is really a continuum of muscle activation involving all of the trunk muscles, each exhibiting a different level of involvement, depending on the type and pattern of movement.

This means that it is highly unlikely that you will be able to totally isolate the ‘lower abs’, since there is always accompanying involvement of many other stabilizing and mobilizing muscles.

This, of course, has not answered the other issue which we raised earlier. If there is differential innervation of the obliques and transversus, must we then conclude that we should recognize upper and lower portions of these muscles, too? We have to bear in mind, even though essentially the same nerves are involved in activating the abdominal musculature, that different

Does this not imply then that one single exercise should be able to exercise all of the trunk muscles? Another point – if one sits up, then both the absand the obliques have to become involved in flexion, as a consequence of basic biomechanics – but what about transversus which is more strongly activated by coughing and forceful expulsion of air from the lungs (or by initiation of walking)?

Give your views on the concept of upper vs lower exercise of the abdominal musculature, including the obliques. Quote any relevant references or personal findings to corroborate your reply.

Change a Pattern… Lose the Fat

Posted on by

A couple years ago, I put on 23 pounds during the winter months. I love watching college basketball, and I follow my favorite teams during conference play, March Madness and the NCAA championships. At the end of college basketball season, I get caught up in the NBA playoffs. To increase my enjoyment, my habit was to have a beer or two along with my favorite snacks. Also, because of a lingering cold, I got out of my usual routine of working out. So it’s no mystery to me why I gained the weight.

Shocked at what I saw on the bathroom scales, I returned to sensible eating and regular exercise, and 6 months later I had lost all the weight, and then some.

Last year, I vowed not to gain the weight back again. I maintained my regular exercise program, and I stayed away from beer and chips. Unfortunately I substituted red wine and mixed nuts. Yes, these foods are said to have positive health benefits, but they are rich in calories and I managed to gain 11 pounds. As I looked at myself in the mirror, I had to admit that I hadn’t broken my pattern at all.

What’s a habit? Most people don’t know that the behavior patterns we call habits are “hard-wired” in the cerebral cortex of the brain. If you do the same things over and over, dendrites from neurons related to the behavior will grow towards other specific neurons to make the connections needed to execute the behavior. This creates a neuronal pathway that makes the satisfying behavior automatic—a pattern. You no longer have to try to make it happen. It just feels right and you do it.

Habits, then, have a physical basis in the brain. This explains why they are so hard to break.

But people do change habits. They’re successful because they substitute an alternative behavior pattern that also satisfies the need, hopefully without the negative side effects. Repeating this pattern creates a new neuronal pathway. Once the new habit is ingrained, the new behavior pattern also becomes easy and automatic. If you don’t return to your old ways, over time the old pathway, like an unused highway, will eventually deteriorate from lack of use.

Knowing all this, I created a delicious substitute for my usual glass of wine. I simply squeezed a one-quarter segment of lime into a glass of cold club soda (soda water). This drink is healthy and has practically no calories. And it tastes great! For variety I would sometimes jazz it up a little with a fruit drink.

Instead of chips or nuts, I substituted fresh fruit: berries, cherries, grapes, pineapple segments, or orange slices. Occasionally I’d have half a bag of microwave low-fat popcorn or some baked chips with salsa.

This year, I felt the craving for wine and nuts, but I substituted my healthy snacks instead. It worked! By the time I got to March Madness, I automatically poured my lime concoction, which I enjoyed. I only gained a couple pounds, which I quickly lost as I increased my activity during the summer.

Remember: habits ARE hard to break, but you CAN do it. The key is to maintain your fitness habits while sticking with your alternative. The new pattern must be:
1. Nutritious and low in calories
2. Just as satisfying as the unhealthy habit

If an obsessed basketball fan like me can do it, so can you!

Don’t Hibernate! Some Ideas for Family Winter Outdoor Fun

Posted on by

This winter season don’t let your family hibernate inside. Why not
put all that fresh snow to good use? Bundle everyone up and participate in some
fun activities the whole family will enjoy.

There are all kinds of ways for kids and parents to enjoy the outdoors
together in the winter. Along with the typical winter sports, there are also
games and creative projects that children really enjoy — and the exercise is
good for them too.

Here are some ideas from the experts at Wham-O to help get kids off the couch
and outside for interactive snow play this winter:

* Head for the sledding hill. Now with so many sledding options, the whole
family will have a blast whooshing down snow-covered hills. In fact, kids and
parents can ride together on the huge, double-walled Turbosaucer Snow Saucer. Or
cause a storm of excitement with the 43 inch SnowBoogie Thunder, a super-light,
shock absorbing foam sled with an ultra-fast SpeedSlick bottom, sure to produce
thunderous applause and crowd-pleasing cheers all winter long.

* Don’t leave the little tots in the “snow” dust. A Baby Sled is a
great way for parents to safely introduce their young toddlers to sledding,
while smaller sleds, such as the Sledz Racer Jr. and the Snowboogie Racer Jr.,
let younger kids hit the slopes by featuring lightweight foam designs to absorb
shocks and a Speedslick bottom for maximum fun.

* Build a cutting-edge snowman with a Snowman Kit. Kids can let their
imaginations run wild as they build a snowman sporting a Mohawk, earring, nose
rings and sunglasses. The Snowman Kit, which contains weather-tough plastic
components, also comes in a traditional version with a black top hat and scarf,
for a more classic-looking snowman.

* Build a classic snow fort — all you’ll need is snow. Create a big mound
and pack it down by stepping, jumping and even rolling on it. Once a solid,
round pile has been created, make a doorway and begin tunneling into the mound.
Continue to shovel snow out of the center and pack it on top. Once inside, use a
smaller shovel to make a space inside. You can cover the floor with a straw mat
and poke holes through the ceiling and sides to make skylights and windows. Snow
fort walls should be at least one foot thick.

Get the most out of your abdominal workout

Posted on by

There are so many people looking for the secrets to great abs. You see all the hype on TV infomercials. Companies peddling all types of equipment that will help you build rock hard abs and a miraculous mid section. Without spending tons of money or any money at all, I’ll discuss a simple and effective way of building great looking abs. It can be done at home or at your gym.

Now we all want defined, toned abdominal muscles. Mostly to look great. A lot of men strive for a 6 pack or close to it, while most women’s goal is for a tight toned mid section. Let me stress that besides the cosmetic reasons for having great looking adominals, having a firm and toned mid section has many other benefits. You’ll ease any extra stress a belly or extra weight puts on your back, improve your posture, increase your stamina and endurance because you are not carrying any extra weight and improve your self esteem. You’ll feel even better about yourself and what you have accomplished. Anyway, this is pretty basic knowledge, but it is good to reflect on why you want to have solid great looking abs.

To develop solid abs, you need to shed some excess body fat. This is accomplished by eating properly and consuming less calories each day than your body burns.

Secondly, your abdominals must be trained in accordance with proper resistance training. I’ll discuss Ab Crunches as an effective exercise to build your abs.

Ab crunches can be performed anywhere:

Starting Position:
Place your hands crossed on your chest and lie flat on the floor with your knees bent. By bending your knees you’re providing your lower back with support. You can also place your hands behind your head if you prefer, but this position often leads to poor posture and unnecessary strain on your neck. In other words, you also end up cheating by lifting yourself using your arms and neck rather than your abs.

Performing the Exercise:
Slowly raise yourself using your abs, with your lower back always pressed against the floor. Raising your lower back will put unnecessary stress on your back. There are many exercises specifically for your lower back and remember, the abdominals create the exercise. Following the same method, slowly lower yourself.

Sets:
Try 4 sets of 24 with a short rest in between. The great thing about abs is that they can be exercised every second day or on consecutive days depending on your time and workout schedule.

Variation:
Try the same procedure by raising your legs or when you want to work on your obliques. Most people forget about working the oblique muscles (your side stomach muscles). Lie on the floor the same way as for regular crunches and cross your legs over to begin the exercise. If this feels uncomfortable or difficult, you may want to try the exercise standing up.With a reasonable weight in one hand, slowly lower one side and then return to the starting position. Repeat the procedure on your other side.

These are just a few of the many ab exercises that you can perform almost anywhere.
