Newsletter #119 --- The danger of exercise and the role of good nutrition
While exercise is good for our health, working out too much can be dangerous and a waste of time!
The danger is real for both tiptop athletes and middle-agers trying to work off the holiday paunch - from muscle strain, sprain, stress fractures, torn cartilage, insomnia to compromise of their immune systems.
William Haskell, professor at the Stanford School of Medicine, says that the risk of harm begins to outweigh the benefits for adults after more than an hour a day. Dr. Mehmet Oz said that over exercise can create more oxidative stress, in which oxygen molecules called free radicals are formed that damage DNA and cells, and over time, oxidative stress has been linked to many health problems including cancer.
During the last 20 years there has been an alarming increase in the number of cardiovascular deaths among professional, Olympic, collegiate, high school and serious recreational athletes. We should expect between 70 to 80 percent of serious athletes to suffer some cardiac related damage. No athlete regardless of their age, gender, size, or level of athletic prowess is immune from the negative impact from the following factors.
1. Nutrient deficient foods that contain chemical additives.
2. Environmental toxins that permeate our food supply, water and air.
3. The negative impact on health of electromagnetic pollution.
4. The stress damage of exercise.
5. Society's overuse of prescription drugs and medical technology for treating all health and injury related problems for athletes.
On September 25, 2005 The Orange County Register of California newspaper published an article entitled "Heart of the Matter," that chronicled the death of 14 young athletes who recently died from heart disease. 10 of the 14 deaths were male athletes who were under 21 years of age. The youngest was just 13. Research reports have shown that over 50 percent of the athletes who suffer sudden cardiac death have a condition called hypertrophic cardiomyopathy (HOM).
It is urgent to implement clinical nutrition programs for all classes of athletes in the United States to curb this emerging epidemic.
Exercise Induced Pathology (EIP)
Dr. Jeffery Skee, Ph.D., has been in practice for over 25 years in Clinical Nutrition. He specialized in dietary and supplementation programs for athletes. In the last 5 years he has focused on medical research and nutraceutical product developement.
In his observation- professional athlete has extensive inventory of health and career benefits. This should translate into a 15 to 20 percent increase in longevity. Since the average male in America has a life expectancy of 76 years, professional athletes should live to be 87 to 91 years. Shockingly, when Dr. Skee studied the mortality data taken from the Major League Baseball Hall of Fame, it showed that this elite group of athletes born in the modern era of professional baseball (after the year 1900) had a mortality experience between 62 and 72 years. The 12 acknowledged superstars during this era in MLB had the shortest average life of 62 years.
Dr. Skee concluded that exercise stress related to frequent vigorous training and competition is responsible for this significant reduction in life expectancy. Exercise Induced Pathology is responsible for over 80 percent of the stress damage to an athlete's body that contributes significantly to the expression of heart disease as well as other chronic degenerative diseases like, multiple sclerosis, and ALS or Lou Gehrig's disease
Exercise Induced Pathologies are,
1. Free Radicals (Exercise produces millions of these destructive elements which damage the heart).
2. Acids (Disrupt the energy chain and directly damage tissues throughout the body).
3. Ammonia (Headaches, blurred vision and cellular damage which preferentially impacts brain function).
4. Inflammation (C-reactive protein CRP, a health negative consequence of vigorous exercise).
5. Thermogenics (Heat kills athletic performance, releases toxins and starts free radical reactions).
6. Direct Cellular Damage (Compression hemolysis damages muscle and blood cells).
7. Hormonal Disruption (Catabolic hormones liquefy muscle tissue and stops the anabolic drive).
8. Chemical Toxicity (Chemical-induced free radical pathology which starts at birth).
Good nutrition is the foundation of both health and life.
Good nutrition is the solution to Exercise Induced Pathology.
Dr. Michael Colgan is internationally respected authority on exercise and nutritional science, He said, "Exercising without nutritional protection is downright unhealthy."
The great Nobel winning scientist Dr. Linus Pauling founded Orthomolecular Medicine (OM) in 1968. Orthomolecular Medicine (OM) uses the powers of clinical nutrition which employs individual nutrients (amino acids, vitamins, mineral, essential fatty acids, probiotics, vitamin co-factors, etc.) as medical treatment to correct underlying nutritional deficiency.
Literally thousands of medical studies have demonstrated the value of essential nutrients (particularly Vitamin E, vitamin C, and Coenzyme q10) in supporting cardiovascular health. Vitamin E is a powerful antioxidant which emphasizes its importance in supporting the health of the cardiovascular system. Vitamin E's primary role is to mitigate the destructive effects of free radicals that are implicated in almost all chronic degenerative diseases. It helps prevent the oxidation of both vitamins A and C. Vitamin E works synergistically with other nutritional antioxidants like vitamin C, coenzyme Q10, selenium and zinc to mitigate free radicals allowing cellular biochemistry to optimize its functions.
In a 2004 study, Dr. Mastaloudis supplemented male and female runners with a placebo or with a combination of 1,000 mg/day of vitamin C and 400 IU/day of natural vitamin E for six weeks prior to running a 50-kilometer ultramarathon. Plasma levels of vitamins C and E, and markers of oxidative stress (F2-isoprostanes) were measured before, during, and after the race. As expected, F2-isoprostanes increased during the race only in runners given placebos. In the placebo group, the levels of F2-isoprostanes in women quickly returned to baseline shortly after the race, whereas they were still elevated in men six days later. Antioxidant supplementation was beneficial because it inhibited the formation of F2-isoprostanes, which are involved in proatherogenic activities.
Vitamin C deficiency was shown to be one of the key risk factors in the pathogenesis of cardiovascular disease in the early 1940s and 1950s. In 1992, Dr. James Enstrom of UCLA School of Medicine published a epidemiological study involving more than 11,000 Americans over a ten year period. This study showed that vitamin C consumption of at least 300 milligrams per day support their heart health and was associated with an increase in life expectancy of up to six years.
A recent study with athletes that involved using a post-exercise supplement of protein, carbohydrate, and antioxidants (PCA) in the form of a shake showed a significant reduction in free radical formation resulting from vigorous exercise. In this study, two groups of athletes were administered either a carbohydrate sports drink or a protein/carbohydrate/antioxidant (PCA) shake immediately after exercise. Free radicals were reduced 69 percent at twenty-four hours post-exercise in the group receiving the PCA shake. This study demonstrates the significant biochemical and physiological advantage an athlete would have by instituting a nutritional program that included a PCA post exercise recovery shake immediately after a training session. The PCA shake was vastly superior in mitigating free radical buildup when compared to the carbohydrate sports drink. In a similar study using PCA nutrient supplementation, Ready and colleagues at St. Cloud University reported a 37 percent reduction in blood creatine phosphokinase (CPK), which is an important biochemical marker for muscle damage. Since all serious athletes train at least four times per week, these findings have significant implications for the long term health of every athlete.
These nutrition-based protocols will help curb the emerging epidemic of cardiac mortality among all classes of athletes.
Introducing
Pro-PCA Fuel designed by Dr. Jeffery Skee for the athletesPro-PCA Fuel is a revolutionary new sports nutraceutical formulation created to mitigate the health and performance damaging factors that result from vigorous exercise. Pro-PCA Fuel is the first product that provides a dosage schedule for the nutrient fueling needs of three classes of athletes based on their physical size. In addition, it also targets nutrient fueling proactively by administering the dosage during the three distinct phases of the training cycle:
1. Pre-Exercise (nutrient loading).
2. The Training Session (continued nutrient fueling).
3. Post Exercise Recovery (critical for every athlete).
These nutrient fuels work synergistically to mitigate the temporary physical effects of vigorous exercise while promoting improvements in exercise capacity and endurance. PCA nutrient fueling also reduces the collective impact of Exercise Induced Pathology.
Using PCA nutrient fueling after exercise, athletes will reduce 69 percent of free radical damage, reduce 36 percent of exercise induced muscle CPK damage. They also will have 225 percent increase in protein synthesis and a 375 percent increase in net protein balance.
Using Pro-PCA Fuel protocol will maximize multi-dimensional health and performance benefits for every serious athlete, which include the following:
1. Limits free radical damage to muscles and other tissue.
2. Dilutes acids that form during exercise.
3. Restores glycogen and electrolytes.
4. Reduces the production of ammonia.
5. Stimulates the anabolic hormone insulin.
6. Increases protein synthesis during training.
7. Limits catabolic hormone production.
8. Prevents damage to the immune system.
9. Improves hydration which helps manage thermogenics.
10. Increases antioxidant reserves which has a positive impact on both inflammation and chemical toxicity.
Taking Pro-PCA Fuel before and after exercise will also be beneficial in reducing free radical damage for non-athletes.
