About glucosamine

Posted on February 5, 2018 by tamika

Glucosamine

Glucosamine is a compound naturally found within the cartilage of our joints, made from chains of sugars and proteins bound together. It acts as one of the body’s natural shock-absorbents and joint lubricants. Glucosamine possesses natural anti-inflammatory and anti-aging properties. One of the most popular supplements taken by people with bone and joint pain glucosamine aids in treating common symptoms of age-related disorders like arthritis and osteoarthritis.

Using glucosamine supplements or obtaining it from natural sources increases the amount of cartilage and fluid that surrounds our joints. This helps prevent joint breakdown and reduces pain.

Glucosamine slows down deterioration of joints when used long-term, plus it offers other benefits that prescription painkillers cannot (such as lowering chronic inflammation and improving digestive health).

Chondroitin

Chondroitin is a natural substance found in the human body and a major component of cartilage, which helps build connective tissue throughout the body. Because it works by retaining water, it helps add lubrication and flexibility to tissue and joints.

Chondroitin used with glucosamine helps lower symptoms associated with loss of collagen and cartilage, which are found in tendons, joints, ligaments, skin and the digestive tract. These conditions can include tendonitis, bursitis and so on. In healthy people, when cartilage becomes damaged due to overuse, injury or inflammation, new cartilage is normally produced to take its place. Unfortunately, as we get older our ability to regenerate lost cartilage and repair damaged connective tissue becomes less efficient.

In both humans and animals, glucosamine and chondroitin stimulate the production of new cartilage and can also help reduce inflammation in the process.

About L-glutamine

Posted on January 30, 2018 by tamika

L-glutamine is the most abundant amino acid in the bloodstream.

L-glutamine benefits the body in the following ways:

1. Improves gastrointestinal health because it is a vital nutrient for the intestines to rebuild and repair

2. Helps heal ulcers and leaky gut by acting as a Band-Aid for protection from further damage

3. Is an essential neurotransmitter in the brain and helps with memory, focus and concentration (

4. Improves IBS and diarrhoea by balancing mucus production, which results in healthy bowel movements

5. Promotes muscle growth and decreases muscle wasting

6. Improves athletic performance and recovery from endurance exercise

7. Improves metabolism and cellular detoxification

8. Curbs cravings for sugar and alcohol

9. Fights cancer

10. Improves diabetes and blood sugar

Doing approximately one hour of exercise can cause a 40 percent reduction of glutamine in the body. It can also cause suppressed immune function. This has a negative impact on your resistance training and may lead to overtraining syndrome.

Supplementing with L-glutamine allows your muscles to fight and push a bit further, which boosts your strength and helps repair your skeletal muscles.

L-glutamine supplementation makes it possible to recover quicker from intense weight training sessions because it improves muscle hydration. This aids the muscle recovery process and reduces recovery time for wounds and burns.

L-glutamine also burns fat and builds lean muscle mass by helping suppress insulin levels and stabilize blood glucose. This enables the body to use up less muscle mass to maintain blood sugar and insulin sensitivity in the cells. For this reason, L-glutamine benefits diabetics and those with sugar and carb cravings as well.

About beta-alanine

Posted on January 24, 2018 by tamika

Beta-alanine is a non-essential amino acid. It is not used by the body to synthesize proteins. Instead, together with histidine, it produces carnosine.

Carnosine reduces lactic acid accumulation in your muscles during exercise, which leads to improved athletic performance.

In muscles, histidine levels are normally high and beta alanine levels are normally low, which limits the carnosine production.

Since beta alanine supplements increase carnosine levels in muscles, they help the muscles reduce their acid levels during exercise. This leads to reduced fatigue.

Beta-alanine improves athletic performance. It can reduce fatigue, increase endurance and boost performance in high-intensity exercises.

In general, muscle acidosis limits the duration of high-intensity exercise.

For this reason, beta-alanine specifically helps performance during high-intensity and short-duration exercise lasting one to several minutes.

It’s possible that beta-alanine improves body composition by increasing training volume and promoting muscle growth

L-carnosine’s health benefits are generally due to its antioxidant properties, which support many age-related conditions. The specific uses of L-carnosine include support for the skin, joints, digestive system and memory. Carnosine also prevents changes in the structure and function of proteins in the body. This may give it some anti-aging properties.

Moreover, carnosine seems to elevate nitric oxide production. This may help against the aging process and improve immune function.

Lastly, carnosine increases the quality and function of muscles in the elderly.

It is generally recommended to consume 2-5 grams of beta-alanine daily. Taking it with a meal may be even more effective.

The most common side effect of beta-alanine is paraesthesia.

This is an unusual sensation typically described as “tingling of the skin.” It’s usually experienced in the face, neck and back of the hands.

The intensity of this tingling increases with dosage size. It usually starts with doses of 800 mg or higher, and disappears 60–90 minutes after consumption. But there is no evidence that paraesthesia is harmful in any way.

Wawan WBCAA recovery contains 1.8gr of Beta-Alanine, 10gr of BCAAs and 2.5gr of L-Glutamine, with 12gr of carbs – it makes it a perfect intra workout drink.

About diabetes – part 1

Posted on January 1, 2018 by tamika

There are 3 main types of diabetes mellitus:

Type 1 Diabetes: results from the pancreas failing to produce enough insulin

Type 2 Diabetes: a condition of defective insulin signalling

Gestational Diabetes: a condition where women without previously diagnose diabetes exhibit high blood glucose levels during pregnancy.

When insulin isn’t produced or acts ineffectively, glucose remains circulating in the blood, leading to a condition known as hyperglycemia. Long term hyperglycemia can result in the dysfunction and failure of various organs and systems, including the eyes, kidneys, nerves, heart and blood vessels.

The key players in diabetes are the pancreas and the liver.

The pancreas is both an endocrine and exocrine gland.

Exocrine means that it’s a gland that release its contents through a tube from inside to outside the body. It helps with digestion by producing important enzymes that break down food, which allows the body to absorb the nutrients.

The endocrine function primarily involves the secretion of the 2 primary hormones relevant to diabetes management: insulin and glucagon.

Insulin increases the storage of glucose, fatty acids and amino acids in cells and tissues and is considered an anabolic hormone. Insulin is a key player in the storage and use of fuels within the body.

Disorders in insulin production and signalling have widespread and devastating effects on the body’s organs and tissues. Glucagon is a peptide hormone produced by alpha cells in the pancreas. The pancreas releases glucagon when blood sugar levels fall too low. It opposes the action of insulin by raising the concentration of glucose in the blood.

Dietary carbs are not essential, however, the body needs glucose. The brain typically needs about 130 gr of glucose every day. Not all glucose has to come from the diet because the liver has the ability to synthesise it.

The liver serves as a warehouse for glucose storage and production. It can also produce fatty acids under certain conditions.

As blood glucose and insulin levels increase, the liver increases its absorption of glucose. Glucose is stored as glycogen. The amount of glycogen stored depends on circulating insulin and glucose levels. When blood glucose levels drop, insulin production falls. The shortage of insulin signals the liver to release its assets by sending glucose back into the blood to keep the body nourished.

When carb intake is restricted, it lowers blood sugar and insulin levels. As insulin levels fall and energy is needed, fatty acids leave their respected fat cells and enter the bloodstream. From here they’re taken up by specific cells and metabolised. Ketone bodies are molecules created in the liver, that are pushed into the blood stream where they’re utilised by skeletal and heart muscles cells as fuel. Also, the brain begins to use ketones as an alternate fuel source when blood levels are high enough to cross the blood-brain barrier. When this happens a person is said to be in nutritional ketosis.

Ketogenic diets are very popular because they suppress insulin and that seems to be very effective in the treatment and management of obesity and T2D. However the severe restriction of carbs (often below 30 gr) may increase the potential for hypoglycaemia of people with T1D.

Lipogenesis is creating fat within the body from glucose or other substrates. It takes place mostly in the liver. Lipogenesis occurs in the liver during times of calorific excess and overfeeding. The liver converts excess glucose to fatty acids. These fatty acids can be stored in the liver or transported via lipoproteins (carriers) to muscle and fat tissue for future fuel use or storage. The ratio that is stored or used is highly dependent on energy intake vs. energy expenditure.

In a healthy liver, insulin halts the production of glucose and instead promotes glycogen storage or generates fatty acids during times of energy excess.

The liver of a person with T1D has no internal break system. Insulin deficiency allows glucose production in the liver to go uncontrolled leading to hyperglycaemia and ketoacidosis if unmanaged. When there’s not enough insulin available, glucose cannot enter the cells for use as energy. Therefore the liver produces even more glucose in an attempt to provide energy for the starved cells, but because insulin is not available, none of this glucose can enter the cells. It builds up and starves the cells even further. Consequently, administration of insulin medication is needed to facilitate the entry of glucose into cells.

Insulin increases glucose uptake in the liver by facilitating the creation of glycogen and decreases glucose output.

Prolonged elevations in insulin that result from an energy surplus increase the body’s ability to produce fat via the process of lipogenesis.

My message for beginners

Posted on February 13, 2017 by tamika

A short video for those of you who contacted me on social media asking me questions about how to lose weight or get bigger.

The health benefits of foam rolling

Posted on January 16, 2017 by tamika

The idea of foam rollers is simple: using your own bodyweight and agility you roll specific muscle groups against a firm foam roller to mimic a deep massage. You can control how much pressure you apply and you can locate and focus on problematic areas.

They improve blood circulation throughout your skin, muscles, fascia and even tendons and ligaments.
More efficient exchange of nutrients and waste products at a cellular level.
Lengthening of short, tight muscles, tendons and ligaments.
Better posture, stronger core.

When we experience pain or stiffness around weight-bearing joints (hips, knees and spinal joints) a very effective approach is to increase the blood circulation around the problematic area through deep pressure work and stretches.

Sometimes short and tight muscles and ligaments are the root cause of pain and stiffness in the joints.

Some foam rollers and softer, others harder. However it is always you, who controls the pressure that you put on a certain area.

About refined carbs

Posted on January 11, 2017 by tamika

Not all carbs are created equal. There are lots of whole foods that are high in carbs but still incredibly healthy and nutritious.

And there are refined or simple carbs, that have most of their nutrients and fibers removed. Eating refined carbs can lead to many illnesses including obesity, heart disease and type 2 diabetes.

So what are refined carbs?

There are 2 types of refined carbs:

Sugars, like high fructose corn syrup and table sugar
Refined grains: grains that have their nutritious and fibrous part removed. The biggest source is white flour made from refined wheat.

Refined carbs have been stripped off most of their fiber and vitamin content therefore they are considered empty calories. They also absorb quickly in the bloodstream, therefore they have a high glycemic index (GI).

Sugars and refined carbs are a very large part of the total carb intake in many countries.

The main sources of refined carbs are: white pasta, white rice, white flour, white bread, pastries, sodas, snacks, sweets, breakfast cereals and added sugars.

Because refined carbs are low in fiber and digested quickly they cause major swings in blood sugar levels. Foods with high GI promote short term fullness, lasting for about an hour. Low GI foods promote long term fullness, lasting for 2-3 hours. Blood sugar levels drop after about 1-2 hrs eating refined carbs. This promotes hunger and stimulates cravings. When you crave food, you’re prone to overeating.

Refined carbs can cause inflammation in the body which could be the primary cause of obesity and leptin resistance.

Studies show that a high consumption of refined carbs is linked with insulin resistance and high blood sugar levels. These are the main symptoms of type 2 diabetes. Refined carbs also increase blood triglyceride levels which is a risk factor for both heart disease and type 2 diabetes.

However not all carb foods are bad. There are many foods that contain healthy carbs because they’re great sources of fiber, vitamins and minerals. These include:

oats
buckwheat
quinoa
bananas
sweet potatoes
beetroot
oranges
blueberries
grapefruits
apples

How to boost the immune system?

Posted on January 3, 2017 by tamika

The immune system is an interactive network of organs, cells and proteins that protect the body from viruses and bacteria or any foreign substances. The immune system works to neutralize and remove pathogens like bacteria, viruses, parasites or fungi that enter the body, recognize and neutralize harmful substances from the environment, and fight against the body’s own cells that have changes due to an illness.

The cells of the immune system originate in the bone marrow, then migrate to guard the peripheral tissues, circulating in the blood and in the specialized system of vessels called the lymphatic system.

When our immune system is working properly, we don’t even notice it. It’s when the performance of our immune system is compromised that we face illness. Underactivity of the immune system results in severe infections and tumors of immunodeficiency, while overactivity results in allergic and autoimmune diseases.

Give your immune system a boost with these tips:

Supplement with echinacea: Research shows that one of the most significant echinacea benefits is its effects when used on recurring infections.
Supplement with probiotics: Probiotics are good bacteria that help you digest nutrients that boost the detoxification of your colon and support your immune system.
Eat more ginger: It’s believed that ginger helps to break down the accumulation of toxins in our organs due to its warming effects. It’s also known to cleanse the lymphatic system,our network of tissues and organs that help rid the body of toxins, waste and other unwanted materials.
Eat more berries: berries are full with antioxidants, that are excellent for promoting healthy immune response.
Get more rest: restful sleep is absolutely essential for health and recovery. When you sleep certain protective cytokines in your body increase in levels, and inflammatory cells decline, which means that less sleep could result in a deprived immune system.
Have some garlic: it is great to avoid any cold, flu or other viruses. If you don’t like the taste of it, try capsules.
Aerobic exercise boosts immune system: people who are fit and active are less likely to suffer from illnesses and the symptoms are less severe.

For athletes: 9 science based ways to lose weight

Posted on September 10, 2016 by tamika

Recently I’ve come across an article that talks about 9 science-based ways for athletes to lose weight. When you think about it, it’s always more difficult to lose weight when you’re always training, always eating clean. Humans need a certain amount of bodyfat to maintain basic functions. Too much bodyfat – however – can negatively affect an athlete’s performance. So what can athletes do to ‘step up’ their weight loss to be in prime condition and shape?

The first point this article suggests is to lose weight off season. We are talking about b athletes in general. It does make sense to try and lose the excess bodyfat offseason because it’s very difficult to reach peak fitness while dieting. When you’re not eating enough calories, your athletic perfomance will suffer. Losing weight offseason will give you more time to lose the excess bodyfat as well, so that you don’t have to rush the fat loss and can stick to the healthy pace of 0.5 kg / week – minimising the muscle loss.
Avoid crash diets. I think we don’t really need to prove this point, athletes know that they need a certain amount of calories to be able to perform at the training sessions. Also drastically reducing your caloric intake will affect your metabolism and hormonal balance. Athletes should only cut their calories by no more than 300-500 kcal a day.
Eat less sugar and more fibre. Low carb diets are proven to be the best for fat loss. However restricting the carb intake too much will affect your athletic performance. To reduce the carb intake cut out added sugars, and avoid cane juice, dextrin, maltodextrin, barley malt, caramel, fruit juice concentrate, fruit juice crystals and any type of syrup. Instead increase your intake of vegetables high in fibre.
Increase your protein intake. Protein promotes fat loss in several ways: high protein diets increase feelings of fullness and the number of calories burnt through digestion. High protein diets also prevent muscle loss during periods of weight loss. Therefore athletes restricting their calories to lose weight should eat between 1.7 – 2.8 gr protein / kg of bodyweight / day.
Spread protein intake throughout the day. 20-30 gr protein per meal is sufficient to stimulate muscles to produce protein for the following 2-3 hrs. Eating a snack containing 40 gr protein before bed can increase muscle protein synthesis during night. This may help prevent some of the muscle loss expected during sleep.
Refuel well after training. Eating the right foods after competing or training is very important for the athletes, especially when trying to lose bodyfat. Proper refuelling is very important especially on days when you have more than 1 events with less than 8 hours recovery time. Carbs with protein can speed up recovery time and promote protein production in your muscles.
Strength training can also help holding on to the muscle when trying to lose bodyfat. Research shows that both protein intake and strength training stimulate muscle protein synthesis and combining the two can produce an even better effect.
After your diet, increase your calories gradually. It may be tempting to start eating normally again after you’ve reached your desired body fat percentage, but that would lead you to gain bodyfat back. Gradually increasing your caloric intake can help restore your hormone levels and metabolism better, minimizing the weight gain.
Here are some other ways you can achieve weight loss:

measuring your portions and keeping track of what you eat is scientifically proven to help you get better results.
drinking before consuming a meal can help you consume 22% less calories
eat slowly, aim to take at least 20 mins for a meal
avoid alcohol
get enough sleep, not enough sleep can increase hunger and appetite by 24%. Not getting enough sleep will also affect your athletic performance.
reduce your stress. Having high stress levels will increase cortisol levels which promotes food cravings and drive to eat. Mental and physical stress can also prevent proper recovery.

About Creatine

Posted on September 7, 2016 by tamika

Creatine is a protein that is naturally made of 3 amino acids: arginine, glycine and methionine. It can also be found in meat and fish, and can be taken as a supplement.

Creatine combines with phosphorus to form phosphocreatine (PC) in the muscle cells. This fuels your muscles during high intensity training, such as sprinting or lifting weights. Creatine raises PC levels around 2%, which means you can sustain all out effort for longer and recover faster between sets.

Protein promotes muscle hypertrophy and protein manufacture. Lot of studies show that short-term creatine supplementation increases body mass. Studies found that creatine supplements improved strength, the number of repetitions performed to fatigue, and the ability to perform repeated sprints.

How does creatine work?

The gains observed are partly due to the increase of cell volume and partly muscle synthesis.

Creatine cause water to move across cell membranes. When muscle cell creatine concentration goes up, water is drawn into the cell an effect that boosts the thickness of muscle fibres by about 15%. The water content of muscle fibres stretches the cell’s outer sheaths.

In aerobic sports there is less evidence for creatine use. This is probably due to the fact the PC energy system is less important during endurance training.

Who should use it?

If you train with weights, or do any sports that includes high-intensity movements (sprints, jumps or throws: rugby, football, hockey, gymnastics, tennis etc), creatine supplements may help increase your performance, strength and muscle mass.

Taking carbs with creatine can be beneficial, as carb intake increases insulin which helps creatine uptake by the muscle cells.

Creatine monohydrate is the most widely available form of creatine. It comprises a molecule of creatine with a molecule of water attached to it. It requires a loading phase. One way to do it is to take about 20-25 gr / day in 4-5 doses for 5 days. After the loading phase the dosage is 2 gr / day.

The side effects of Creatine:

The main side effect is weight gain. This is partly due to the extra water in the muscle cells, and party to increased muscle tissue. It could be disadvantageous in sports where there’s a critical ratio of bodyweight and speed (like running), or in sports where there are weight categories.
