An 86 Year Old Ironman Inspiration!

In line with last week's post about the amazing Olympic athletes, here's a woman who inspires me to the ends of the earth - meet Madonna Buder, who holds the world record for the oldest person to ever complete an Iron Man triathlon, at the age of... 82!

Buder caught the triathlon bug a little later in life, completing her first triathlon at age 52 and her first Ironman at age 56.  She has completed over 325 triathlons, including 45 Ironman distances (an Ironman is a 3860m swim, 180km bike, followed up by a 42km marathon run).

Now 86 years old, Buder is an inspiration to athletes everywhere, and was even featured in a Nike ad that was aired during the Olympics.

Way to go!!  Thanks so much to my friend Chantelle for telling me about this amazing woman.

Olympic Games - Best Weight At All Sizes

It has been a real inspiration and thrill to watch the elite athletes of the world compete at the Rio 2016 Summer Olympic Games.  Over the last couple of weeks, we have enjoyed watching a wide range of sports, from swimming, to basketball, to gymnastics, to track & field, and so much more.

Take a moment and consider the variation in body shapes and sizes amongst this year's incredible athletes:

Each of these sports have a fierce demand for the highest level of physical ability, the nature of which is unique to each individual sport.  Some require intense upper body strength, while others are more lower body oriented; some high anaerobic capacity; others are all about endurance.

I see a similar diversity in body shape and size in the athletes in my clinical practice as an endocrinologist: marathoners, crossfitters, cyclists, swimmers, football players, and so many others.  The sad reality is that those who are of larger body size will often tell me that they feel judged and assumed to be inactive or 'lazy' based on their shape and size by people who have absolutely no idea what that person is all about.

There is no more poignant reminder than watching these incredible Olympic athletes to never judge a book by its cover.

Do Electric Assist Bikes Count As Exercise?

While highly frowned upon when snuck into the Tour de France (are you kidding me?!), electric bikes can be a very useful piece of equipment to zip around town.  These are bicycles that are equipped with electrical assistance, which is activated only when the rider is actively pedalling.  You may wonder – does using these bikes still count as exercise?  A recent study tells us – yes!

The study, published in the European Journal of Applied Physiology, enrolled 20 people who led sedentary lifestyles, and evaluated several measures of health after 4 weeks of using the electrically assisted bike for at least 40 minutes, three days per week. 

They found that using the ‘pedelec’ bikes provided a moderate level of exertion, similar to walking (4.9 METs on average).  After just 4 weeks, there was an improvement in their glucose tolerance, and an increase in their power output and VO2max (a measure of maximal aerobic capacity).    Participants also found the bikes to be fun, to the point where over half of participants ended up cycling over 50% more than the required amount.

So, while using a regular bicycle would provide more exercise, a pedelec bike is a great option for people who have knee problems, struggle to get uphill on a bike, or if you want to get further in a day than you otherwise would on a regular bike.  (We used them on a trip Kyoto last year so we could make it to all the far flung temples we wanted to see – fantastic!)    Pedelecs remove the potential deterrents of cycling such as longer distances or hills, and they can be incorporated into daily life as a means of transport when the weather/climate permits (rather than having to find specific extra time in the day to exercise).
