My Lower and Mid Back Areas Were Hurting

I went on a two week business trip, and I was literally exhausted when I got home. I thought it was because I did not sleep well because of the uncomfortable bed at the motel, but it turned out to be something else. I gave myself a few days to get back to normal, but my tiredness soon turned into pain. I knew something was wrong with my back, and I still attributed it to sleeping on a bad mattress. I made an appointment with a Petaluma chiropractor, hoping that I would be able to get this taken care of sooner rather than later.

I had been to a chiropractor years ago because of a car accident I had been in, and the one I saw was able to help me with a pretty severe case of whiplash. That is why I wanted to see another chiropractor since the pain seemed to be mainly in my lower and mid back area. The one I had seen years ago has probably been retired for a dozen years because he was an older fellow when I had seen him.…

Does Coolsculpting Work on Flab?

I have been trying to lose about twenty pounds for a good long time. It is about gone now and I am thinking about the results that I have achieved. Of course I am about to do the last leg of this, I am within a couple of pounds of being where the body mass index things say that I should be. At any rate the weight is nearly gone, but there is a lot of flabbiness on my sides and on my belly. This friend of mines showed me this web page, www.balconesdermatology.com and told me that they do this cool sculpting there. I really did not have a good idea of what that meant at first.…

I Can Tie My Shoes Again

One of the first things I wanted to do when I moved to California was look for a reputable chiropractor in the San Francisco area. I know a lot of people will look for other professionals first, like an attorney, a doctor, a dentist, or even a hair stylist. For me though, there are very few things in this life that are more important to me than making sure I have regular spinal adjustments done. Anyone who has lived with excruciating back pain can understand that, because it is one of the worst pains I have ever had.

It really does incapacitate a person. It is hard to do a lot of things when your back is hurting. If your arm is hurting, you can still walk. If your leg is hurting, you can still type at a computer. When your back is hurting, it is hard to do just about anything. I had trouble sleeping because I could never get comfortable. I had trouble sitting because I had to keep shifting. I had trouble standing because the pain was so bad.…

I Was Involved in a Car Accident

I was involved in what I thought was a minor car accident not long ago. A car rear ended me, and it pushed me into another car. Altogether, this chain reaction involved six cars total, and we all thought that we escaped with just minor injuries. It was not until the day after the accident that I knew something was wrong because my neck hurt more than it ever has. I decided to give it a couple of days, but my husband told me that either I go and see a Huntington chiropractor or go to the hospital.

I honestly did not think that it was anything major, so I opted to wait at least another day.…

Can Viagra Increase Athletic Performance

My friend, Scott, used Twitter to ask me about Viagra a couple weeks ago. He was riding on his trainer and saw an advertisement on the TV about Viagra….and he was wondering if it could enhance his athletic performance.

Here’s what I’ve learned….

Introduced in 1998, Viagra is one of the trade names for the compound, sildenafil citrate. Manufactured by Pfizer, this drug is used primarily to treat erectile dysfunction (ED), but it has also found niche uses as well for the treatment of pulmonary arterial hypertension (PAH, high blood pressure in the lungs) and altitude sickness. Viagra is similar in properties to both Cialis (tadalafil) and Levitra (vardenafil).

By inhibiting an enzyme in the penis called cGMP-specific phosphodiesterase type 5, Viagra actgs by increasing bloodflow that produces an erection. We call drugs like Viagra vasodilators because they dilate the blood vessels. It’s taken in a pill form, at a dosage of 25 – 100 mg, and is recommended for use not more than once per day, sometime between 30 minutes to 4 hours prior to sexual intercourse.

But if Viagra can produce greater bloodflow in the penis, could it also produce increased bloodflow elsewhere in the body? And, as a result, might it lead to increased oxygen delivery to the muscles in a way that could enhance athletic performance?

Interestingly, we learned during the Balco investigation that many professional baseball players and other athletes were using Viagra as an on-field performance-enhancing agent. In fact, in 2008 Victor Balco claimed that the use of Viagra was even more common than the use of creatine.

The science about Viagra and athletic performance is actually very sparse.

Interest in this regard was stimulated by a study of 14 mountaineers and trekkers by a group of investigators at the University of Giessen in 2004 [1]. They studied the athletes using a cycling test at near sea level (in Giessen), with a reduced-oxygen environment, and again at Mt. Everest Base Camp (5245 m). They found that Viagra increased the maximum workload in each setting and concluded that “sildenafil is the first drug shown to increase exercise capacity during severe hypoxia both at sea level and at high altitude.”

There’s been just 1 other study in humans to show a direct benefit of Viagra on athletic performance [2]. A group of investigators from Stanford hypothesized that Viagra would improve the cardiac output (CO), arterial oxygen saturation (PaO2), and performance at altitude (relatively low oxygen environment), but would have no effect at sea level (with a normal level of atmospheric oxygen). They studied 10 cyclists with a 10 km time trial (TT) at both sea level and simulated high altitude (3874 m). At sea level, Viagra had no effect on the outcome measures. At altitude, Viagra produced higher CO, higher PaO2, and a 15% improvement in time for the 10 km TT. On review, though, the investigators found that there were actually 2 subgroups: a group of Viagra responders, who improved their TT performance by 39% and a group of non-responders who improved their TT performance by only 1% (which was not statistically significant). The authors concluded that Viagra can greatly improve cardiovascular function and performance in a low-oxygen environment for certain individuals.

But, of course typical athletes don’t compete at altitudes of 2+ miles!

The issue of whether Viagra might affect athletic performance drew the world’s attention heading into the Beijing Olympic games in 2008. In assembling its list of banned substances for 2008, the World Anti-Doping Agency (WADA) wrote:

“As regards sildenafil (Viagra), WADA is aware of studies presented in relation to the potential of sildenafil to restore pulmonary capacities at very high altitudes. WADA is currently funding a number of research projects on the effects of sildenafil at various altitudes. These projects are ongoing.”

Indeed, Viagra has not yet been added to the WADA list of banned substances.

In summary, then, Viagra is useful for the treatment of ED and PAH. Although there is some evidence of performance-enhancing effects on athletic performance (in some individuals) at altitude, there is no evidence that Viagra improves performance in typical athletic activities.…
