Muscle Toning Exercise

Filed under: Uncategorized — amit @ 10:34 pm

The benefits of toned muscles go beyond just looking good.  For example, toned muscles in the abdominals will help to support the low back and decreases the likelihood for low back pain.  Also strengthening the upper back muscles will help to improve posture.  The question I hear a lot is whether to use weights or not.  My answer is this… it’s up to you!  You don’t need weights to tone the body, however, weights are great to do too.  I recommend a combonation of weights and toning without weights.  You can achieve a toned physique either way!  Using your own body weight and doing exerecises such as pushups and tricep dips tones the upper body.  One thing I recommend prior to using weights is to do exercises without weights to learn proper body mechanics and therefore reduce the chance of injury.

Exercise for Women

Filed under: Uncategorized — amit @ 4:46 am

I specialize in exercise for women because there is a difference in the needs for men and women.  Men typically want to get bigger muscles, while women want to tone up and trim down.  Men typically lift heavy weights, while women shy away from weights for fear of “bulking up”.  At one time in my life I was really into natural body building.  I have a naturally muscular build, so with effort I can get big muscles..but I also learned that I can make my muscles long and defined.  It’s true that your body can change with the exercises you do.  For that reason I have found that doing a combo of light weights, kickboxing, and yoga plus good healthy eating habits has given me and many of the women I work with amazing results.  As far as getting big muscles…most women won’t get them unless they work really hard at it, and have a mesomorph build (or a naturally muscular body).  My advice is to try a variety of exercises over a 3 month period of time and see how your body changes by the type of exercise you do.

Postpartum Exercise

Filed under: Uncategorized — amit @ 8:33 pm

So, you have had a baby…what do you do now?  As a personal trainer and aerobic instructor the most common questions I get are, “When can I start exercising again?”  and “What exercises can I do that are safe?”  My advise to the first question is to get the thumbs up from your doctor prior to exercising.  Usually a doctor will give the thumbs up 4-6 weeks after having a baby vaginally or 8-10 weeks after having a C-section.  Even if you feel great shortly after delivery, your body takes time to heal from the inside.  Often times women are eager to get their body back so they start working out intensely too early.  This can result in and increase in bleeding and a longer delay to getting back to exercising.  C-sections take even longer to heal since the abdominal muscle is cut.  Once you get the go ahead from your doctor start off slowly with walking, swimming, and basic yoga.  Gradually build up the intensity.  If you were exercising througout your pregnancy you will get back your intensity quicker as well as your pre-pregnancy form.   If you did not exercise during your pregnancy get back on track now!  You will feel better about yourself, and you will be a great role model for your children.

Bioperine

Bioperine

Bioperine is a standardized piperine extract obtained from the fruits of the Piper nigrum, also called ´black pepper´ and/or Piper longum, also called ´long pepper´. Those fruits are hand harvested in India, just prior to ripening and then sun dried to assure their maturity and quality.
Although black pepper is a common household spice, its extract has also been used extensively for medical purposes, especially in Ayurvedic medicine. Its main action is to significantly enhance the bioavailability of supplemented nutrients through increased absorption and transportation into the blood. In fact, bioperine is the only product sourced out of piperine to obtain a patented status for this ability.
In the fat loss field

Its action is being widely exploited in these terms, since many dietary supplements include vitamins, mineral, amino acids and antioxidants that are better absorbed and used because of the bioperine action. For example, Nutrition Research has published a double blind, crossover trial in which the effectiveness of an extract from the fruit of black pepper, with a minimum 98% pure alkaloid piperine was evaluated for its ability to improve serum response of beta-carotene during oral supplementation.

Subjects were randomly selected to ingest a daily beta-carotene dose (15 mg) either with 5 mg of piperine or placebo during each of two 14-day supplementation periods. The selection of volunteers was limited to healthy adult males with fasting serum beta-carotene values < 20 mcg/dL, in order to minimize the inter-subject variability in pre-supplementation of serum beta-carotene levels.

After the 14-day period, the results indicated significantly greater increases (p < 0.0001) in serum beta-carotene during supplementation with beta-carotene plus piperine (49.8±9.6 mcg/dL vs. 30.9±5.4 mcg/dL) compared to beta-carotene plus placebo. Supplementation with beta-carotene plus piperine also produced a 60% greater increase in area under the serum beta- carotene curve (AUC) than the one observed during the beta-carotene plus placebo supplementation.

Bearing all these results in mind, experts explained the theory that the serum response during oral beta-carotene supplementation might be improved through non-specific, thermogenic property(s) of piperine, which are known as ´thermonutrient´ action. The word ´thermonutrient´ is used because of its ability to increase the absorption of nutrients comprising nutritional supplement formulations, as well as the body’s natural thermogenic activity utilizing the daily food apart from nutrients.

This increased bioavailability of supplemented nutrients caused by bioperine may be derived also from a strong enough increase in the thermal energy, to emphasize the natural thermogenic activity just named. So this action leads to some enhanced metabolic processes, which create more demand of a broad range of nutrients that contribute to metabolism, such as the ones that dietary supplements in general contain.

In another similar study, supplementation of 120 mg of coenzyme Q10 with piperine for 21 days also produced a statistically significant area (p=0.0348) -approximately 30% greater- under the plasma curve (AUC) than observed during supplementation with coenzyme Q10 plus placebo.

Dosage and side effects

So far, there are no reported side effects. Based on double blind clinical data, Sabinsa –the company that legally manufacturers and supplies bioperine- recommends to use it in the amount of 5 mg per dose but does not require this level in customer’s formulation. Bioperine taken in this dose, enhanced the blood levels and bioavailability of a wide range of nutrients, both fat and water soluble, by over 30-60% in studies. Powder should be diluted with other nutrients at 100-200 doses per gram of bioperine before use. It is also advised to take no more than 20mg/day.

In addition, blood tests revealed that the absorption of nutrients was markedly increased when bioperine had been administered earlier –e.g., selenium levels were increased by 30%, and vitamin B6 by more than 60%. As the optimal utilization of nutrients and minerals depends on the intake of food in terms of time, the additional intake of black pepper alone, or during the meals would have no particularly positive effects on the metabolism. So, before the meals is when bioperine can be taken most advantage from.

Phosphatidyl Serine

Filed under: Main, Phosphatidyl Serine — amit @ 12:42 pm

Phosphatidyl serine
Phosphatidyl serine is a naturally occurring phospholipid that has a structural role in the biological membranes of plants, animals and other life forms. It is found in fish, green leafy vegetables, soybeans and rice, and is essential for the normal functioning of the brain cell membrane, in which it is more concentrated than in the rest of the cells.
Improving cognitive function
Phosphatidyl serine helps regenerate damaged nerve cells, reversing defects in nerve cell message transmission, helping to establish new receptor sites in the brain. It also supports the functions of several important membrane proteins. In fact, large protein molecules station themselves like sentries along the phospholipid wall, where they perform a variety of important functions like those recently named. More specifically, they process enzymatic and hormonal signals from outside the cell, catalyze the nerve cell’s mitochondrial energy production, facilitate the release of neurotransmitters, and support the functions of the proteins in the neurotransmitter receptors of dendrites. That is why phosphatidyl serine is usually used to benefit memory, learning, concentration, mood, alertness, and reaction time. 
In the largest multicenter study to date of phosphatidylserine and Alzheimer’s disease, 142 subjects aged 40 to 80 were given 200 milligrams of phosphatidylserine per day or placebo over a three-month period. The scales normally used to assess Alzheimer’s status were used, and showed that those treated with phosphatidylserine showed an improvement on several items. Although the differences between placebo and experimental groups were small the experts catalogued them as ´statistically significant´.
Phosphatidylserine has also shown some efficacy in some non-Alzheimer’s dementias, in age-associated memory impairment and general mental deterioration. Although more clinical trials need to be conducted before elaborating conclusions, taking into a count the results to date, plus the fact that there are very few side effects associated with phosphatidyl serine and also so few treatment options for Alzheimer’s disease, one research group concluded that the therapeutic possibilities offered by phosphatidylserine should not be dismissed.
Cortisol –against fat loss

In terms of fat loss, phosphatidyl serine is not known for having a direct effect on this field. However, it is commonly included in many fat loss supplements in order to reduce muscle soreness, as it is said to suppress cortisol, which is known to break down muscle tissue and also contribute to abdominal fat storage.

According to a study performed at University Hospital in the Swedish city of Gothenburg, elevated cortisol levels provoked by both emotional stress and physical stress -like sleep deprivation and vigorous exercise- stimulates a fat-gathering enzyme, which is more easily taken up by the abdomen than other parts of the body.

However, several phosphatidyl serine supplementation seems to blunt cortisol release significantly secondary to stress. In fact, the journal Biology of Sport published a study in which phosphatidyl serine supplementation reduced cortisol levels by 30 percent compared to a placebo following exercise.

Dosage and forms
Phosphatidyl serine supplements can be derived from bovine brain or from soy lecithin. However, in the case of phosphatidyl serine taken from bovine cortex, it is usually not sold because it may contain viruses or infectious agents inadvertently introduced in the phosphatidyl serine product when extracted from the animal brain. So the phosphatidylserine currently available is derived from soy. In this case, it undergoes an enzymatic process that converts phosphatidyl choline -another major phospholipid found in egg yolks and soy- to phosphatidyl serine.
As it is common to use the results of studies done with phosphatidyl serine from cow brain to hypothetically prove that soy derived phosphatidyl serine is also effective, the reader should distinguish between both sources. Apparently, the extracts taken from bovine cortex contain other brain components apart from phosphatidyl serine, which may have led to better improvements in brain function than the ones taken from soy. So, when trials are performed using BC-phosphatidyl serine, they are referring to the one taken from bovine cortex, and not the one extracted from soy.
There is preliminary research indicating that the dose of phosphatidyl serine for inhibiting exercise-induced increases in cortisol ranges from 400 up to 800 mg per day, while other sources suggest to take 100 milligrams three time daily.
Although it is not contraindicated with any known medication, the lack of long-term safety studies suggests phosphatidyl serine should be avoided by children, pregnant women and nursing mothers. Also, those suffering from the antiphospholipid-antibody syndrome should exercise caution in the use of phosphatidylserine and only take it under medical supervision and monitoring.
