Health Benefits of E-Bikes

At Cycling CME and in the Human Performance Lab at Colorado Mesa University, where we have many cycling advocates, we frequently discuss cycling, trails, and new bikes. Recently, e-bikes have become part of our discussions. Those discussion have ranged from types of e-bikes, where they should ride, and whether we might ever buy one. One thing that does seem clear is that e-bikes are here to stay, as sales of e-bikes have skyrocketed in the last few years and e-bike rentals have increased remarkably. This fall we have seen an increase in e-MTBs cruising our home trails around Grand Junction and Fruita, Colorado. This will likely increase with the recent order signed by the Secretary of the Interior which will potentially allow electric bikes on BLM land and National parks. This may allow e-bikes onto any federal trail where non-motorized bicycles can ride.

Our debates in the lab include the speed of e-bikes, environmental concerns, commuting benefits, and how they might enforce different classifications of e-bikes on trails and paths. Although there are legitimate concerns related to e-bikes on both paved and mountain bike trails, there is clear evidence that e-bikes increase participation in cycling for groups of people who might not otherwise cycle. Even regular cyclists who buy e-bikes increase their time in the saddle. Of special interest to Cycling CME, early studies show that riding an e-bike is good for your health.

One of the first studies that evaluated the health impact of e-bikes was done at Colorado University, in Boulder, Colorado. In a group of sedentary individuals, they found improvement in cardiovascular fitness and blood sugar levels within one month and e-cycling helped them meet their physical activity recommendations. More recent studies have looked at the benefits of e-bikes in older riders. A study from Belgium showed an increase in activity in a group experiencing limitations in ability to cycle with e-bike use. A study published this year by Leyland suggested that both pedal bikes and e-bikes can increase physical activity. In addition, the authors felt that physical activity wasn’t the only health improvement component. They suggest that the ability to ride a bike outdoors improves both cognitive function and well-being in the older adults who participated in their study…cycling plus the outdoors.

Entering the discussion on where e-bikes should be allowed, and other e-bike related issues, is a topic we must continue to explore. Love them, or not, e-bikes and on the rise and they encourage people to exercise and enjoy the outdoors. At Cycling CME, we always encourage that.

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.
