Good News For Bodybuilders!

Osteoporosis (thinning of the bones) in men is a condition usually limited to old age. However, the condition is more prevalent in women of younger age categories.

Many bodybuilders believe themselves to be immune from the risks, because of their healthy lifestyles.

This belief may not be backed by fact.

Many studies have been done on protein intake and urinary calcium excretion (calciuria). All have found that increased protein intake is correlated with an increase of calcium in urine (calcium that cannot be used by the body).

This has led to many athletes supplementing with calcium. While this may be a viable option, so too is something else: increase your potassium intake!

A recent study and ireland has shown that consuming high levels of table salt (nacl) increases calcium loss in urine. The best way to combat this loss is to increase your potassium intake.

Getting enough potassium is important for athletic performance, and the best way to do this is to eat plenty of fruits and vegetables daily.

Does The Bodybuilding Patch Really Work?

Recently, the testosterone patch has become popular. Originally conceived of as a medical treatment, supplement companies have seen value in marketing transdermal patches to deliver steroid hormones.

The big question has always been: do they really work?

According to a recent study, yes. Thus study had 108 male participants use the patch by placing it on their scrotum's for a period of 36 months.

The double-blind, randomized controlled trial found that the group who received the patch had significant decreases in bodyfat and increases in body mass compared to the control group.

This illustrates that transdermal patches are effective at delivering their contents. Results will depend, for the most part, on how well the delivered substance elevates testosterone levels once in the body.

Blood Doping? That's Old School.

Athletes are always looking for an edge. With the competitive nature of the bodybuilding world, who can blame them?

For years blood doping has been a standard practice amongst elite athletes. Now, that is about to change.

Blood doping is a procedure that involves adding a performance enhancing substance to the blood and then returning the enhanced blood to the body. Now, science has discovered a better way: genetic doping.

At the elite level of sport, genetics can mean the difference between winning or losing. So, it is no wonder that athletes would seek to equalize this factor.

Genetic doping is a procedure where a gene is coupled to a virus (for delivery purposes) and then injected into the body. The gene then expresses itself in the body, giving the athlete advantages he or she never would have had.

There are considerable safety (and ethical) issues associated with this procedure.

It does sound like something from a comic book, but genetic doping is the wave of the future.

In our view, it will revolutionize bodybuilding as we know it. Remember that you heard it at first.

Milk: It's Good Stuff!

Igf-1 is one of the most powerful hormones available to bodybuilders. Many bodybuilders use it in conjunction with testosterone to benefit from the synergy of the two hormones.

A study by heaney et al. (1999) has shown that milk has powerful effects on the bodies output of igf-1 - insulin like growth factor-i.

The researchers had the study participants consume 1 pint of milk per day. After 12 weeks on this milk regime, researchers took blood samples and compared them to samples taken before the study.

Both the male and female participants had an increase of igf-1 levels of 14 percent. That represents an increase of more than 1 percent per week!

Recently, many bodybuilders have been questioning the wisdom of drinking milk; claiming that it contributes to excess body fat storage, and causes excess water to be stored under the skin. For non-competing athletes, drinking milk is fine.

Make no mistake: as long as milk is the low in fat, it makes a great bodybuilding food and can help you add quality size.

Want More Igf-1? Eat Protein.

Bodybuilding is a game of hormone manipulation. From eating habits to exercise methodology, the goal is increased muscle mass through the stimulation of the bodies endocrine system.

Bodybuilders have long known the benefits of a high-protein diet. But, now researchers have discovered another bonus: increased igf-1 levels.

A study conducted on 82 elderly patients has revealed consuming a mere 20 grams of protein per day for six months can lead to an 80 percent increase in serum igf-1 levels.

While not directly applicable to bodybuilders, the study highlights the important and powerful role of protein within the body. If a mere 20 grams of protein per day can have these effects on the untrained, just think of what 1 gram of protein per pound of body weight and a sound training regime will do!

High-Intensity Training Works Even For The Advanced Athlete!

Time and again research demonstrates that you are never too old to become physically active.

A study conducted on elderly women and men has demonstrated that using a high-intensity resistance training over a period of eight weeks can increase strength levels by an amazing 174 percent! The study also showed lean mass gains of 10 percent over the same time period.

The participants in the study were at an advanced age. It should be expected, therefore, the younger persons will reap even better results due to an increased ability to adapt to stimuli. Anecdotal evidence from bodybuilders around the world demonstrates that high-intensity training works extremely well.
