Sports Medicine:
Being active and athletic is one of
the most rewarding experiences in our lives. Exercise not only conditions our muscles or
maintains a healthy body weight, but it stimulates our minds and our immune systems.
Exercise is the most basic of life changes that we can make to ensure a healthier body for
the future and prevent disease.
The three fundamental aspects to increase
fitness are endurance, strength and flexibility. Strength training is usually done by
resistance exercises using weights. It involves the increase in muscle cell size
(hypertrophy) instead of an increase in the number of muscle cells (hyperplasia). Think of
a muscle cell like an electrical wire that is covered in plastic. Muscles get bigger
because more wires are added inside the plastic coating, making the cell larger. Endurance
or aerobic exercise is the continuous motion of muscles for an extended period of time.
Flexibility is the increase in range of motion across a joint. All three aspects are
important for a healthy fitness routine and the prevention of injury.
Exercise is the very starting point on
the road to great health. You also must eat right and take the right supplements to keep
your body energized. No matter what type of athlete you are, you can enhance your
performance by making correct nutritional choices with food and supplements. Your body
will have more requirements as you increase your exercise or increase the intensity. As we
age our bodies have a tendency to become more injury prone and take longer to recover.
Supplements can make a significant difference in all of the components of exercise. There
are so many supplements and claims in the market of nutritional medicine, and Dr. Metcalfe
wants to make it easier for you to understand and be
the best that you can be.
Endurance:
Endurance training is otherwise known as
aerobic exercise. Its most profound effect on the body is with the cardiovascular system
(heart, arteries, and veins). Your heart rate or pulse measures the intensity with which
you exercise. The heart rate is directly related to the intensity of the exercise. As the
intensity increases and you work harder, the heart rate increases. The maximum heart rate
remains a constant in all individuals, and exercise will not change this figure. Maximum
heart rate is measured by subtracting your age from 220. Aerobic exercise increases so
much blood flow through the heart that it decreases the hearts demand for oxygen
even while at rest. The heart increases its muscular walls and the ventricular chambers
increase in thickness. It also lowers the resting heart rate (bradycardia), so that the
heart doesnt have to work as hard to pump blood to the rest of the body. This is why
exercise is so important for people with heart disease, because it makes the heart
stronger and more efficient.
Ergogenic aids are those that claim to
enhance energy utilization during exercise. Its pretty simple, you must provide your
body with energy or else it cant do the work. Your body utilizes its energy in
various ways depending on the intensity with which you exercise. Intensity is usually
measured by your heart rate (pulse). ATP, adenosine triphosphate is an energy rich complex
consisting of adenine (amino acid), ribose (sugar), and a tri-phosphate bound to either
magnesium of manganese. Your body breaks ATP down with the help of calcium to provide a
powerful source of energy. The problem with ATP is that the body utilizes its entire
stores within the first 2-3 seconds of exercise. The body then turns to a second
high-energy source of phosphocreatine, which it utilizes within the next 10 seconds. In
sprinters it is utilized even more rapidly. It is then, that the body must begin using
other forms of energy either from fat stores or glycogen. If you workout at a low
intensity (low heart rate), your body will utilize energy initially from ATP in the
muscles, then utilize energy from fat stores of the body. In a typical 70Kg male, the
energy stored in fat is about 135,000 Kcal, so there is plenty of stored energy. However,
as exercise intensity increases, the body immediately utilizes ATP, then begins consuming
glycogen, which is stored in the muscle. As long as the body is exercising at an aerobic
level, the body will utilize glycogen. However, glycogen stores last on average about
forty minutes at a high intensity. As glycogen stores decrease, the body then starts
utilizing fat stores. You can see the importance of refueling your body with food as you
continue to exercise past forty minutes. Its like fueling a fire, it wont
continue to burn without wood! It is essential that you consume carbohydrates during
longer training and racing events because your body will start breaking down muscle
protein for energy. This is counterproductive for an athlete trying to strengthen his
body.
There are also 2 types of skeletal muscle
fibers in our body and the proportion of both is genetically predetermined. Fast twitch
muscle (white fibers) is unable to utilize oxygen effectively and produce relatively small
amounts of ATP, but they can contract very quickly. Sprinters are typically dominant in
fast twitch fibers. Slow twitch muscle (red fibers) are much better utilizers of oxygen
and produce high amounts of ATP for longer periods of time. Marathoners or distance
cyclists have a predominantly higher proportion of slow twitch fibers. Exercise cannot
change the types of muscle fibers in your body, but it does make them more efficient.
Ergogenic aids are definitely required
for anyone doing moderate to high intensity exercise, have blood sugar imbalances, or for
low intensity exercisers that are active for longer than a couple of hours. It is
important for an Ergogenic aid to contain more than just sugar. Dr. Metcalfe believes the
best product on the market for endurance are those that contain minerals and other
cofactors essential in muscle metabolism.
The nutritional needs of an endurance
athlete must include the following:
Calcium:
Males and Females 1000 mg daily. This is
an essential nutrient for muscle contraction.
Dr. Metcalfe recommends supplementing calcium, as it is so essential to muscle function.
If you get more from your diet on a certain day then you can take a little less calcium,
but extra never hurts. Foods that contain calcium are dairy products, leafy greens,
broccoli, almonds, salmon, and tofu. She recommends taking calcium with your pre-workout
meal, some more right after you exercise, and again before bed for relaxation.
Cal-Plex: An excellent calcium supplement,
which contains L-Arginine a precursor for growth hormone, which helps drive calcium into
bones. Take 2 capsules with breakfast, 2 post-exercise and 2 before bed.
Magnesium:
Males and Females 600 mg daily. Some
magnesium supplements will cause diarrhea, so Dr. Metcalfe recommends Mag Glycinate, which doesnt cause
diarrhea. Magnesium is essential for ATP utilization for energy. Magnesium is readily lost
during sweating and through the urine from sugar ingestion. Red blood cells also require
magnesium to function and healthy red blood cells means more oxygen to the body. Early
onset of fatigue while exercising may be due to low magnesium, along with cramping and
nausea. Foods that contain magnesium are vegetables, fish, nuts, and seeds.
Mag Glycinate: 2 tablets three times
daily. 2 with breakfast, 2 post-exercise and 2 before bed.
Glutathione:
Glutathione is essential for repairing
cellular damage caused by oxidative damage from prolonged exercise. It is essential for
DNA synthesis and repair, liver detoxification, immune system enhancer and a potent
anti-oxidant. Even though youre exercising, your increased oxygen consumption is
harmful to cells. Glutathione is essential in all athletes, especially those that live in
larger metropolitan areas and are exposed to smog.
Recancostat 100: this product contains
100 mg of glutathione along with antioxidants. Dr. Metcalfe recommends 1
capsule twice daily.
Potassium:
Males and Females should make sure that
they drink a potassium rich drink as they exercise. You should also reload after exercise
with 100mg of potassium for every hour you have exercised! Food sources of potassium
include bananas, avocados, and dried figs. Potassium is readily lost through sweat and
urine. Potassium is essential in maintaining the energy of each cell in the body. When you
exercise, cells release potassium into the blood stream and this may contribute to
fatigue.
Endura Lemon Lime: carbohydrate
replacement drink contains 180 mg of potassium per serving.
Endura Orange: carbohydrate replacement
drink contains 180 mg of potassium per serving.
Mag-K Chela Max: 1 capsule upon
completion of exercise for every hour of exercise. If more than 3 hours, divide capsules
into 2 every two hours.
Vitamin C:
Males and Females 1000 mg every morning
and evening with a full glass of water. Food sources include fruits and vegetables.
Vitamin C is essential in the formation of collagen and connective tissue such as
cartilage, and it has potent anti-oxidant benefits. It potentiates your immune system,
particularly your white blood cells to fight off illness.
Ultra Potent C 1000: 1 capsule twice daily
with a full glass of water.
Glutamine:
Males and Females 2gm daily. Glutamine is
an amino acid, which is made by the liver. It is fast becoming one of the most studied
nutrients for endurance. Food sources of glutamine include raw spinach. Glutamine is
required for muscle anabolism (growth) and a precursor for human growth hormone. It is
also a good buffer for preventing lactic acid accumulation in muscle tissue during
anaerobic metabolism. This decreases the onset of muscle soreness and fatigue. Glutamine
is also being studied further for its effect on fat loss. It may do this because of its
ability to lower high blood insulin levels. Glutamine is also used by the central nervous
system in the production of neurotransmitters. During endurance events, our brains can use
a little extra help!!! Glutamine is also essential for maintaining a healthy intestinal
mucosa level. This mucosal level may get depleted due to the stress of competition and may
minimize pre-competition diarrhea.
Permeability Factors: 6 capsules
contain 1.5 mg of glutamine along with gamma oryzanol and other essential nutrients to
enhance nerve cell function and endurance. Take 3 capsules twice daily.
Vitamin E:
Males and Females 800 iu a day. Vitamin E
is an anti-oxidant, which protects cells from the oxidative effects of exercise. It may
also be important in increasing anaerobic threshold and decreasing lactic acid production.
Foods that contain Vitamin E include corn, wheat germ, nuts and seeds. It is important to
make sure you take a "natural" vitamin E as opposed to a synthetic form.
Vitamin E: Take 2 capsules daily with
food.
Protein:
Males and Females should eat 1 gm of
protein for each pound of their body weight daily. Protein is essential for providing the
amino acids, which are the building blocks of muscle tissue and neurotransmitters of the
nervous system. Endurance athletes require extra protein because of the catabolic effect,
which occurs on long training days. Amino acids will help prevent depression and fatigue.
Food sources of protein should primarily come from fish, lean meats, low fat dairy
products, and protein drinks.
Progain: An excellent pre and post
exercise drink when its too hard to eat. This contains carbohydrates as well as
protein.
Ultra Advantage Bar: An excellent protein and carbohydrate food source for before, during
and after exercise.
Ultrabalance Protein: A protein only drink mix. Excellent for adding extra protein in the
diet.
The endurance athletes cupboard
should contain:
Endura: High Magnesium Energy and
Rehydration Drink. This product is an excellent balance of nutrients to support muscle
metabolism. You can vary the concentration depending on the type and length of workout you
are doing.
Orange Flavor Endura
Lemon-Lime Flavor Endura
Endurabolic: 2 tablets before working
out with a carbohydrate drink like Endura, and 2 tablets after exercise.
Mag Glycinate: 2 tablets before
exercising, and 2 before bed at night. This also helps calm restless legs.
Multiplex: 3 capsules twice daily with
meals. A comprehensive multivitamin which supports your extra nutritional needs.
Permeability Factors: 3 capsules
before working out and 3 afterwards.
Cal-Plex: 2 capsules with breakfast, 2
capsules post-exercise and 2 before bed.
Recancostat 100: 1 capsule twice
daily.
Ultra Potent C 1000: 1 capsule twice
daily.
Vitamin E: 2 capsules a day with food.
Ultrabalance protein or Ultra advantage bars or Progain for added protein sources.
Mag-K Chela Max: 1 capsule for each
hour of exercise, taken after exercise.
Multiplex Multivitamin (without iron for men, with iron for
women): 3 capsules twice daily with meals. This is an excellent quality multivitamin to
supply your body with extra nutrition.
Muscular Development:
Resistance training with weights or
by using your own body as a weight leads to muscular development. One of the major
benefits of weight training is that muscle tissue has a higher resting metabolic rate than
fat tissue. The more muscle you have, the higher your basal metabolic rate, and therefore
the more calories you burn on a daily basis. This is what makes weightlifting an essential
component to anyone trying to lose weight. Weight training while dieting helps spare the
destruction of lean muscle mass. Having stronger muscles makes you less prone to injury,
improves posture, and looks wonderful.
Muscle cells respond to resistance
training because of the contractile force placed upon them. A muscle cell is composed of a
bundle of fibers. The more trained the muscle, then the thicker the bundle within each
cell. Muscle fibers depend on cellular calcium and nerve stimulation to contract. When a
muscle is forced to contract it initially only recruits a small amount of fibers. However,
as a muscle is forced to work harder, the nervous system stimulates larger groups of
fibers to contract. It is estimated that for the first 20 weeks of weight training, the
most important physiological change is the increase in nerve stimulation to more muscle
tissue. This is called neural hypertrophy. However, for the first twenty weeks, muscle
fiber hypertrophy is slow, but once this point is reached and you continue training,
muscle cell growth leads to larger muscles. To simplify this, what is required initially
to get stronger is to have more nerve stimulation to the muscle cells. This requires
training. Then the muscle cell size will increase.
Hormone levels are also very important to
muscle anabolism (building) or muscle catabolism (breakdown). Testosterone is by far the
biggest anabolic agent and it does this by increasing protein synthesis. The hormone
insulin is anabolic because it makes cells more permeable to glucose, so eating or
drinking an energy drink helps muscles repair after a workout because they increase
insulin release. The hormone cortisol, a stress hormone from the adrenal glands, is
catabolic because it counteracts insulin and growth hormone. Cortisol is highest between
6-8 a.m. and is higher in stressed individuals. Estrogen decreases the metabolic rate and
increases fat storage leading to weight gain. Progesterone increases the basal body
temperature and increases metabolism. Human growth hormone is mostly secreted during deep
sleep phases at night and is anabolic because it stimulates glycogen storage in the body.
DHEA is a precusor in the synthesis of androgens, estrogen and corticoids. All of these
hormones require cholesterol as their primary building block.
There is some confusion where some people
think that plants can act as steroids. Plants contain hormones called sterols, which are
similar in structure to cholesterol, which is our bodys building block for hormone
synthesis. In our bodies they bind to cholesterol receptors to exert their effects. Some
of the earliest birth controls in the 1950s were from a plant sterol of wild yams
called diosgenin. Plant sterols can be very powerful in their actions. These include
yohimbine, sarsaparilla, Mexican yam, rice bran oil (gamma oryzanol), soybeans, etc.
There are many nutritional supplements
that can aid the body builder. None of them will give you instantly large muscles, but
they will help you achieve your goals along with hard work.
Lifestyle Changes:
Exercise daily for at least one hour.
Start with 20 to 30 minutes of aerobic exercise and follow that with weight training. Hire
a trainer to design a program for you if you dont know where to start.
Get 8 hours of sleep a night.
Set reasonable goals taking into consideration your work, family and friends.
Enjoy yourself and be brave and try new activities as your strength increases.
Stop smoking.
Avoid alcohol.
Dietary Changes:
Decrease the amount of fat in your diet
to 30% of total calories.
Keep a diet diary and list everything you eat and drink and how you feel afterwards. Do
this for one week. See any bad patterns? Now is the time to change them.
Read nutritional labels on all the foods you buy and eat.
Avoid fast food restaurants.
Increase fiber intake to 30 grams a day.
Increase water intake to 12 glasses daily. Make sure you carry a water bottle to the gym
with you.
Increase protein in your diet to 1gram for every pound of your body weight. You will need
a protein drink to accomplish this. Dr. Metcalfe highly recommends Progain Protein Energy
Nutrition.
Choose only complex carbohydrates as opposed to the simple carbs from white flour, white
rice, boxed sugary cereals, cookies, etc.
Natural Solutions:
Muscle Support Program:
Progain: Protein Energy Nutrition: Use
this as a supplemental protein source to get adequate protein in your diet. This also
contains carbohydrates and is an excellent meal replacement.
Multiplex Multivitamin: 3 capsules twice
daily with meals.
Endurabolic: Take 2 tablets before your
workout with Endura carbohydrate drink or a carbohydrate snack, then take 2 tablets
immediately after working out.
EZ Flex: 2 capsules after your workout, and 2
before bed.
Permeability Factors: 3 capsules
twice daily.
Ultrabalance Protein: this is an excellent protein powder that contains vitamins.
Ultra Advantage Bars: an excellent source of protein, carbohydrates and vitamins in a
tasty bar.
Post Exercise Recovery:
The process of recovering after exercise
enables the body to repair the damage that the exercise has done. It is essential to slow
down for 6 to 8 hours after working out to allow the body to heal. An appropriate recovery
enables you to be able to do hard work again faster.
There are two physiological components of recovery. The first is a fast component, which
takes place immediately after stopping exercise. This involves the following physiological
changes:
Resaturation of myoglibin in muscle cells.
Resynthesis of ATP.
A continuous higher respiratory rate to provide the body with more oxygen for metabolism.
70% occurs within 30 seconds after stopping exercise, and 100% completion occurs after
five minutes.
The second part of recovery is the slow component. This process begins within minutes of
ending your exercise to a few hours.
During this time the body is busy oxidizing lactic acid in the muscles.
Glycogen and catecholamines are undergoing synthesis.
Your body temperature remains elevated during this time.
Your respiratory rate should have returned to the normal resting rate (12-15
respirations/minute).
It is important during this time to rest, elevate your legs for twenty minutes, and eat
and drink. You should drink 16-20 oz of water per hour for the next four hours. If you are
feeling nauseated then make sure you have taken your mineral supplements, and eat some
food that has some sodium in it. Ginger tea or candied ginger helps with the nausea and is
a natural anti-inflammatory. The following supplements will help you get back out there
tomorrow. Take them immediately after you are done exercising.
Endura: drink some carbohydrates within
the first few minutes of the completion of your workout.
Endurabolic: 2 tablets.
Mag Glycinate: 2 tablets.
Permeability Factors: 3
capsules.
Cal-Plex: 2 capsules.
Recancostat 100: 1 capsule
Vitamin E: 1 capsule.
Stay healthy, get strong, and be your
best!
