If you are a gym rat or bodybuilder or simply interested in beginning an exercise program you have probably heard a lot about creatine and the muscle miracles it performs. Unfortunately, most people believe that creatine helps build muscle and it does in a way, but probably not the way you are thinking. The best way to describe creatine is to say that it helps the muscles help themselves build muscle. If that is not clear enough, continue reading.
Creatine does exactly what it claims to do and that is to retain water in your muscles. This is the point of creatine and it really is effective at keeping water in the muscles. Now, what happens is when your muscles are retaining water they are in an optimal state for building new muscle. As a result, when you take creatine and water is retained in your muscles then when you weight train you will get more of an effect because your muscles are better capable of building muscle. After this period you may develop more strength and increased endurance as well. So, if you are taking creatine to help you build muscle and you understand what creatine does and how it helps you build muscle then you will not be disappointed. On the other hand, if you are taking creatine and hoping it will simply grow you bodybuilder’s muscles without putting in the work then you are mistaken.
The best thing to do is begin taking creatine and working out with weights on a regular routine or even with a trainer. By taking the creatine your muscles will be poised to grow and get stronger while building endurance. However, keep in mind you have to put in all the hard work and that all creatine does for you is helps your muscles retain water in order to be in a state where building muscle is easier. Over time you will see your muscles growing and should not see any loss of definition because of the retained water in your muscles. Don’t become confused about creatine building big muscles; it just helps your muscles build themselves stronger and better when you put in the work.

Although the above would probably be the major mechanisms by which whey could help the dieter, there are several secondary effects of whey that may assist in weight loss. For example, whey’s effects on serotonin levels. Serotonin is probably the most studied neurotransmitter since it has been found to be involved in a wide range of psychological and biological functions. Serotonin ( also called 5-hydroxytryptamine or 5-HT) is involved with mood, anxiety, and appetite.
Elevated levels of serotonin can cause relaxation and reduced anxiety. Low serotonin levels are associated with low mood, increased anxiety (hence the current popularity of the SSRI drugs such as Prozac and others), and poor appetite control. This is an extremely abbreviated description of all the functions serotonin performs in the human body – many of which have yet to be fully elucidated – but a full explanation is beyond the scope of this article.
Needless to say, Increased brain serotonin levels are associated with an improved ability of people to cope with stress, whereas a decline in serotonin activity is associated with depression and anxiety. Elevated levels of serotonin in the body often result in the relief of depression, as well as substantial reduction in pain sensitivity, anxiety and stress. It has also been theorized that a diet-induced increase in tryptophan will increase brain serotonin levels, while a diet designed for weight loss (e.g., a diet that reduces calories) may lead to a reduction of brain serotonin levels due to reduced substrate for production and a reduction in carbohydrates.
Many people on a reduced calorie intake in an attempt to lose weight find they are often ill tempered and more anxious. Reductions in serotonin may be partially to blame here. One recent study (The bovine protein alpha-lactalbumin increases the plasma ratio of tryptophan to the other large neutral amino acids, and in vulnerable subjects raises brain serotonin activity, reduces cortisol concentration, and improves mood under stress. Am J Clin Nutr 2000 Jun;71(6):1536-1544) examined whether alpha-lactalbumin – a major sub fraction found in whey which has an especially high tryptophan content – would increase plasma Tryptophan levels as well reduce depression and cortisol concentrations in subjects under acute stress considered to be vulnerable to stress.
The researchers examined twenty-nine “highly stress-vulnerable subjects” and 29 “relatively stress-invulnerable” subjects using a double blind, placebo-controlled study design. The study participants were exposed to experimental stress after eating a diet enriched with either alpha-lactalbumin (found in whey) or sodium-caseinate, another milk based protein. They researchers looked at:
* Diet-induced changes in the plasma Tryptophan and its ratio to other large neutral amino acids.
* Prolactin levels.
* Changes in mood and pulse rate.
* Cortisol levels (which were assessed before and after the stressor).
Amazingly, the ratio of plasma Tryptophan to the other amino acids tested was 48% higher after the alpha-lactalbumin diet than after the casein diet! This was accompanied by a decrease in cortisol levels and higher prolactin concentration. Perhaps most important and relevant to the average person reading this article, they found “reduced depressive feelings” when test subjects were put under stress.
They concluded that the “Consumption of a dietary protein enriched in tryptophan increased the plasma Trp-LNAA ratio and, in stress-vulnerable subjects, improved coping ability, probably through alterations in brain serotonin.” This effect was not seen in the sodium-caseinate group. If other studies can confirm these findings, whey may turn out to be yet another safe and effective supplement in the battle against depression and stress, as well as reduced serotonin levels due to dieting.
Although there is a long list of hormones involved in appetite regulation, some of which have been mentioned above, serotonin appears to be a key player in the game. In general, experiments find increased serotonin availability or activity = reduced food consumption and decreased serotonin = increase food consumption. If whey can selectively increase serotonin levels above that of other proteins, it could be very helpful to the dieter.
Other possible advantages whey may confer to the dieter is improved blood sugar regulation (Frid AH, Nilsson M, Holst JJ, Bjorck IM. Effect of whey on blood glucose and insulin responses to composite breakfast and lunch meals in type 2 diabetic subjects. Am J Clin Nutr. 2005 Jul;82(1):69-75.) which is yet another key area in controlling appetite and metabolism.
Finally, calcium from dairy products has been found to be associated with a reduction in bodyweight and fat mass. Calcium is thought to influence energy metabolism as intracellular calcium regulates fat cell (adipocyte) lipid metabolism as well as triglyceride storage. It’s been demonstrated in several studies the superiority of dairy versus non-dairy sources of calcium for improving body composition, and the whey fraction of dairy maybe the key.
The mechanism responsible for increased fat loss found with dairy-based calcium versus nondairy calcium has not is not fully understood but researchers looking at the issue theorized “… dairy sources of calcium markedly attenuate weight and fat gain and accelerate fat loss to a greater degree than do supplemental sources of calcium. This augmented effect of dairy products relative to supplemental calcium is likely due to additional bioactive compounds, including the angiotensin-converting enzyme inhibitors and the rich concentration of branched-chain amino acids in whey, which act synergistically with calcium to attenuate adiposity.”
It appears components in whey – some of which have been mentioned above – are thought to act synergistically with calcium to improve body composition (Zemel MB. Role of calcium and dairy products in energy partitioning and weight management. Am J Clin Nutr. 2004 May;79(5):907S-912S.).
Conclusion
Taken in isolation, none of these studies are so compelling that people should run out and use whey as some form of weight loss nirvana. However, taken as a total picture, the bulk of the research seems to conclude that whey may in fact have some unique effects for weight loss and should be of great use to the dieter. More studies are clearly needed however.
So what is the practical application of all this information and how does the dieter put it to good use? Being the appetite suppressing effects of whey appear to last approximately 2-3 hours, it would seem best to stagger the intake throughout the day. For example, breakfast might be 1-2 scoops of whey and a bowl of oatmeal, and perhaps a few scoops of whey taken between lunch and dinner.
If whey does what the data suggests it does in the above, that should be the most effective method for maximizing the effects of whey on food (calorie) intake on subsequent meals as well as the other metabolic effects covered. If working out, the schedule may be different however and people should follow the pre and post nutrition recommendations made in my ebook “Muscle Building Nutrition” or advice easily found on the ‘net via the many sports nutrition and bodybuilding related web sites.
Continue Reading »It is the dog days of summer, and here in North Carolina it is Hot and Steamy. I’m talking Tarzan jungle hot. It is hot enough that I am making several adjustments to my exercise routine. I normally run outside every day, but this is the time of the year when I least appreciate it. Consequently I am using the elliptical trainer a few days a week, and the other days I head out for a real good sweat.
I’m one of those people who sweat profusely. By the time I am done my body and my gym clothes are soaked. This means I am draining some serious fluids, which is not a problem as long as I adequately replace them, and I monitor any abnormal physical symptoms.
Heat related illnesses are usually due to people ignoring the warning symptoms. They include weakness, dizziness, headaches, muscle cramps and nausea. This means you need to be aware of your mental state. What appears to be fatigue can progress to unconsciousness.
So I have been doing my research and have come up with a list of valuable suggestions to make certain you summer outdoor workouts are healthy and rewarding:
Stay Hydrated
Even in cooler temperatures, there is a tendency not to adequately replace expended body fluids. In the summer it is an absolute necessity. It is important to drink water or sports beverages before and after your workout. If you are engaging in extended outdoor exercise (running, walking, bicycling), replace fluids periodically. For runners, consider a hydration pack. If you do not maintain your fluid levels you risk circulatory failure.
If you are exercising for an hour or less, water is sufficient. Longer than an hour and you need to replace carbohydrates. Warmer weather metabolizes these substances faster. Consider one of the popular sports drinks that contain carbs.
Time of Day
When they are predicting some scourging weather, schedule your workout early in the morning or later in the evening. Avoid the mid-day heat and humidity. Workout indoors if that is the only time you have to exercise
Humidity
Be aware of the relative humidity. The body responds to overheating by the evaporation of moisture through perspiration. When the humidity is high, the air is less capable of evaporating excess moisture. Consequently your natural cooling mechanism is compromised. Monitor your vitals. If you start to feel light headed, or you feel completely drain, immediately stop, find a place to cool off and once again replace those vital fluids.
Cool Clothing
No, I am not talking about the latest fashions. When exercising in heat you do not want clothing that will retain heat. That includes cotton apparel. Go for synthetic breathable fabrics that release moisture from your body and allow efficient airflow. Hats are good for preventing the sun from heating up the blood vessels lining your scalp. But remove the hat occasionally to let the heat escape.
Problems of Pollution
Due to some misguided political policies and our desire to drive gas-guzzling vehicles, the air quality in urban environments in the summer often sucks. During days when there are orange, red or even purple alerts it is best to limit your outdoor activities. And air pollution is not limited to just cities. For example, the air quality in the mountains of North Carolina during the summer can be equivalent to the air in Los Angeles. The trees are actually dying in the high altitudes. Furthermore, the air quality in a number of our national parks and beaches can be potentially hazardous during the summer months. Excessive physical exertion in areas of poor air quality can be detrimental to your health.
The summer offers an incredible opportunity to enjoy the beauty of nature while you exercise. A walk or run on a tree-lined trail or sandy beach surely beats the congestion of a health club. But when it heats up outside use common sense and caution. And if those dog days of summer start barking consider heading indoors.

In view of the fact that Mari Winsor’s Pilates Method was initiated by Joseph Pilates, a German National, there have been a number of unique method of pilates originated such as the in style methods of Aero Pilates, Mari Winsor and even Yoga Pilates.
Even though there are a mixture of methods and variations of free Pilates exercises invented each version concentrates on the basic values established by Joseph Pilates. The objective of this article will be to explore the main movements and methods of a Pilate’s training program.
Movements
Not like other fitness training programs Pilates training methods seek to improve the movements of the body. Since Pilates incorporates many body movements with a lot of motions your core muscles that hold up the your joints become increasingly stronger. The stretching of these foundation muscles permits you to grow to be a more elastic person and therefore the combination of these two makes your body movements smoother.
Body And Mind
Finding the right body and mind represents another core method of the Pilates exercise technique. Most people training with Pilates like the fact that it builds muscle and strength and you will find the same people using Pilates find a gigantic physical fitness advantage of using pilates techniques in their workout. Different Yoga that centers more around stretching, Pilates fitness workouts look to shape key body muscles with basic yet sophisticated methods. Additionally, core breathing techniques of Pilates are used in order to enhance blood flow to the brain which in the end of a workout smooth the progress of stress relief in the body.
Posture
The every day workout like weight lifting or aerobics center on a individual muscle movements. Pilate’s workouts focus on total body movements which are focused on providing a complete workout. This lets lots of people to get a total body training program, yet most of all it gives a established methodology that will keep the body aligned. This helps people who workout with Pilates develop a healthier posture through methods which assist with helping the core of the body. Moreover the strength attained from a Pilate’s workout regime assists to develop body shape which give the body a balanced posture.
Flexibility:
The core of Pilates is based around stretching and developing flexibility in order to decrease stress in the joints and muscles. One of the main reasons for stretching that a good number of perspective pilates members neglect to recognize is that stretching makes up a exceptionally proficient training regime for building muscles as well. Additionally stretching helps prevent injury which is a widespread reason Pilates beginners training with Pilate’s describe such a reduced incidence of injury while working out with Pilates.
Generally Pilates represents a complete body workout program which will supply benefits to the total body and mind by helping diminish stress, enhance posture, flexibility and muscle strength and in time helping with creating a life of balance.
