Mountain Biking Injuries

Living in Western Colorado, we have access to a large variety of excellent mountain bike trails. This diversity of trails includes both high alpine riding and biking in the desert and red rocks. While providing care for both road cyclists and mountain bikers, it is clear that there are some differences in injuries sustained in these two groups of cyclists. The diversity in equipment, terrain, riding style mean different types and prevalence of injuries when riding a mountain bike versus the road bike, and medical providers should be aware of those differences.

We recently published an article in, Lower Extremity Review, reviewing mountain biking injuries. (HERE) One of the interesting areas of working on this review was the lack of research or information on the recreational riders. The majority of research published on mountain biking has involved competition, elite riders or injuries at mountain bike parks.

What is clear is the increasing interest in mountain biking in the United States. There are many reasons for this including improvements in mountain bike technology, improved and more accessible trails and the growing knowledge of the health benefits of cycling. This is clearly evident in our area of the country.

So, get on your mountain bike and enjoy the great outdoors but be careful out there. And if you have a chance, experience mountain biking in western Colorado.

Exercise and Father Time

A Lifetime of Exercise Slows Down Father Time

With significant interest in the mature athlete and aging in general, I found recent articles by Pollock and Duggal et al, in the journal The Aging Cellquite interesting. As we are aware, aging is associated with many physical and cognitive changes. Common physical problems may include immune, hormonal and muscle changes. An example is sarcopenia, the loss of skeletal muscle as we age, which has concomitant loss of muscle mass as well as changes in contractile function.

This research group from the UK has evaluated greater than 125 active male and female cyclists aged 55-79 year old in regards to muscle findings and physiological functions. This group would be considered active as the men were able to cycle 100km in under 6.5 hours and the women 60km in under 5.5 hours.

They compared these adults to a group that did not participate in regular physical activity ages 20 to 80. The study showed that regular exercise diminished the loss of muscle and strength with age. In addition, they had lower body fat and total cholesterol and the men’s testosterone remained higher than the non-exercisers. In addition, the cyclist’s immune system appeared to have less aging as their thymus, which makes our T cells, continued to make T cells similar to the younger population. In the second study, they evaluated vastus lateralis muscle biopsy samples from a subset of these cyclists (n=90). They concluded that exercise was able to mitigate most of the effects of inactivity and aging across the age groups studied.

Very interesting research on the powerful effects of a lifetime of exercise. Be sure to have an active day.
