One important reason for that may have to do with the gut microbiome. What is the gut microbiome and how does it impact our health? How does diet affect the microbiome and what is the relationship between the microbiome and endurance exercise performance? In this episode's medical mailbag, we look at recent research that suggests our microbiome may have an outsized role in how we perform when training and racing. Plus, a conversation...

Men and women differ in many ways and recent research has suggested that one of these may be in how they need to hydrate during sporting activities. Menstruating women start out better hydrated than men and appear to lose less fluid than their male counterparts meaning that different genders may want to consider different hydration strategies. Coach Juliet Hochman and I discuss in the Medical Mailbag. Then, professionals Matthew Sharpe and Chris Leiferman join me to recount what went down in their epic race for the podium with Lionel Sanders at the Boulder 70.3 triathlon...

Stress has long been known to be an important risk factor for cardiovascular disease and is considered an important cause of morbidity and mortality. How psychological stress translates to physical disease has not been well understood though. New research suggests a mechanism for this connection and suggests how regular exercise may serve as a buffer of sorts, decreasing the impact of stress and improving long term outcomes. I review the evidence. Plus a conversation with the founder of nutrition app FuelIn, Scott Tindal. We chat about the importance of iron deficiency in athletes and...

In this episode:

Science is not static and as new papers come out it is worthwhile revisiting previous topics to see if any of my previous conclusions should be updated. On this episode I look at newer research on topics previously covered in several different episodes to see if I should revise what I concluded at that time. Specifically, cold water immersion, platelet rich plasma injections, bicarbonate supplementation and stretching.

Much has been said about how female reproductive hormones can play a role in women's ability to train and race and most of what has been said has come from one woman. The reality though is the evidence paints a very different picture than what too many women have been sold as what to expect. I look at the latest in a growing body of evidence to question the dogma that women should expect to perform differently based on when in their cycle they train.

Garmin wearables measure all kinds of data whenever you wear them and then process that data through various algorithms to present users with composite metrics on training and health. For many, how these are derived and what they mean is very much a mystery while for others they can be a source of consternation especially when your watch tells you that a perfectly good workout was 'unproductive' to your training status! I look at these measures in order to explain how they are arrived at and whether or not you should pay them any...

We know that exercise is good for our health and well being but can too much of a good thing be...not so good? Research has begun to show that in older individuals, the benefits of exercise may diminish after a threshold of volume and intensity is surpassed and a new paper has found that even among elite athletes in their twenties, too much training at too high an intensity might be the cause of cardiac events. I look at what is known about all of this. Scott Tindal has worked with professional athletes...

Over more than three and a half years and fifty thousand plus downloads, the TriDoc podcast has delivered entertaining interviews and informative reviews of the science behind all manner of products marketed to endurance athletes. Now, in my one hundredth episode it is time for me to pause and take a look back in order to once again help you see through the advertising ploys and red flags used to separate you from your hard earned money and review what doesn't work as well as the few things that are worth your time.

In this episode:

Sudden cardiac death (SCD) continues to be a fearsome specter for athletes in all endurance sports but especially for triathletes who have the highest rates of SCD during the swim than for any other activity. To date, no screening programs have proven successful or practical to lower the risk. With improvements in genetic testing, could this avenue offer a possible solution? I look at what the science says. Joanne Courtney had a long and successful career as a professional curler as the second for Rachel Homan's foursome through numerous national championships, Worlds and one...

Gastrointestinal (GI) distress is an exceedingly common complaint among endurance athletes but despite years of research the actual reason for why this occurs remains mostly speculative. Recent research looked at whether or not what an athlete eats and how much of it can play a role in the development of GI issues during a race and the authors set out to determine if the underlying cause of the problem is inflammation and injury. I review their findings and give some specific recommendations with a special guest. Also, a conversation with the amazing Juliet Hochman...
