The context surrounding the study of the impact of testosterone on elite athletes is essential in understanding its underlying hypothesis – that “excess” endogenous testosterone confers a competitive advantage. This is a direct outgrowth of the Dutee Chand’s suspension that was overturned because while “possessing high levels of testosterone and thereby increasing lean body mass creates a competitive advantage,” there was no evidence of endogenous testosterone’s impact. It also explains the apparent conflict of interest of the authors; one the head of the International Association of Athletics Federation (IAAF) [1] Health and Science Department, the other a consultant and member of the workgroup on hyperandrogenic females and transgender issues and was a witness in the Chand case. ...

Left-handed people are a bit of an anomaly. Relatively speaking, there aren't many of them, yet they've been around for thousands of years.

If there was a solid evolutionary advantage to being left-handed, we would expect the frequency of left-handedness to increase in the population. But that isn't occurring. Instead, we observe a low but persistent prevalence of left-handedness, just around 8% to 10%. One explanation is the notion of negative frequency-dependent selection, which means that the trait is beneficial only if it remains rare.

To shed light on this hypothesis, sport scientist Florian Loffing from the University of Oldenburg in Germany examined the prevalence of left-...

Full Disclosure: Before five minutes ago, I was unsure what teams made it into the upcoming Super Bowl. I mean, if one of them isn’t the Eagles, then my attention span plummets to nonexistent.

But, being that “THE” game is apolitical and topical, what better way to contribute some semblance of expertise than through analysis of the ads and how they may or may not reflect the health interests and possible status of the audience? 

Given that the ads are my favorite part of the event anyway, they will be the focus.  Because they are the focus of a lot of people, the ads have become a cultural phenomenon, and so there is real investment in being entertaining. It sometimes makes or breaks companies for the year so they want to appeal even to those not captivated by...

There are a lot of Seahawks haters out there. Apparently, a popular insult hurled at the team is that it is a "Johnny-come-lately" franchise supported by a bunch of bandwagon fans. The problem for the haters, however, is that statistics show it's not true.

To be sure, every team has some bandwagon fans. A statistical analysis of Major League Baseball teams showed a small correlation between success on the field and attendance. Even the St. Louis Cardinals, a team that is considered to have the most loyal baseball...

Staying fit by playing tennis

A recent health story is currently making the rounds proclaiming that some forms of exercise, as well as participation in three particular racquet sports, are better than others for your overall health and will help you live longer.

These online articles invariably attract our attention. Why? Because they carry headlines that provide the simple solution that everyone craves: the way to better fitness, and finally, a clear, unambiguous and athletic path to a long, healthy life.

Sure, these stories do contain some worthwhile information on how to improve one's fitness. But unfortunately, they are the very definition of health hype.

That's because placing emphasis on specific activities is overblown, and the study these stories are based on has a range of...

We like to make it a point not to alarm parents unnecessarily. Part of our mission is to inform the public about health concerns, simply and calmly, without resorting to scare tactics to get attention. And the most recent news about youth sports and eye-related injuries should be treated in just that way.

Eyes and eyesight are vitally important. No question about it. And a recent retrospective study shines light on a health issue that, while important, has recently been overshadowed by other youth concerns, like concussions and severe knee injuries, especially among adolescent and teenage girls. That said, it's good to pay attention to what this new study tells us, learn...

footballFootball is an extremely popular sport in the United States. The number of boys playing football in the US is greater than the combined number of boys playing the second and third most popular sports, according to the National Federation of State High School Association (NFHS). Approximately 3 million youth athletes play football, and 1.1 million high school athletes and 100,000 college athletes play tackle football each year. And as we ve reported before, the US has a dangerously relaxed attitude toward concussions.

footballConcussions have garnered much attention in the sports world recently following news about early dementia and other neurological problems after repeated head injuries. Head trauma from sports ranging from professional boxing to high school football and skateboarding are seen as potentially leading to later deficits and the impact need not necessarily be intense nor lead to loss of consciousness to do serious damage. The crux of the problem has been that even when an athlete sustains a blow to the head, there has been no way to...
