This week on the Training Blog, “is cycling the fountain of youth?” How cycling can bring health and fitness in adulthood, and beyond.
This week I’m going to step back from tips on how to prepare for RAGBRAI and remind everyone that cycling isn’t only a fun activity, but it can potentially increase our lifespan and improve the quality of those years. Ever since Ponce de Leon’s time, people have been searching for the fountain of youth. Little did they realize it was sitting right in their garage – their bicycle! Cycling certainly can give us many of the attributes we seek in youthfulness – aerobic, cardiovascular, and muscular fitness, maintenance of our body weight and composition, metabolic health, a healthy blood lipid profile, and glucose levels. The exercise cycling may help prevent chronic diseases, obesity, cancer and neurological disorders.
Cycling increases aerobic fitness and health

First and foremost, cycling is an aerobic endurance sport. It generates tremendous aerobic fitness which trains the body to be more efficient at burning fat as well as sugar, and modulating blood sugar levels. It creates a stronger heart, increasing stroke volume and pumping out more blood per beat, often resulting in lower resting heart rates. Aerobic training can improve blood lipid profiles (triglycerides and cholesterol) as well, aiding in better cardiovascular health.
In addition, cycling can also improve our anaerobic fitness. As we exceed our aerobic capability, such as climbing a hill, we exceed our ability to perform using available oxygen, and we go into oxygen debt, indicated by heavy breathing. People use the phrase ‘catching their breath’ and that is repaying their oxygen debt. This allows us to function at very high levels for short periods of time, but we can’t keep it up for very long either.
Because cycling is an endurance sport, cyclists tend to be leaner and fitter than the general population in part due to the many hours we can ride each week. A good workout for a runner may be an hour a day, and while a marathoner may run for 3-4 hours at a time in a marathon, they can only run a marathon a few times each year, whereas a cycling can ride 5-6 hours in one day and turn around and do it again the next day (which you will do in RAGBRAI). This allows cyclists to burn thousands of calories per ride daily and develop great endurance. This results in a good body composition with a healthy BMI and body fat percentage if their nutrition is also dialed in.
But we need more than just cycling

So, is cycling the fountain of youth? It sure sounds like it, but it isn’t quite the complete answer.
Cycling is obviously good for lower body strength. Just look at any high-level cyclist, and they have tremendously developed leg and glute muscles from pedaling the bike thousands of reps per ride. Grip strength is another strong indicator of longevity, and while I don’t believe grip strength will necessarily save one’s life, I think it’s a proxy for overall strength. One can’t pull hard on the handlebars or lift a barbell without commensurate grip strength.
So what about strength? Yes, cyclists have great leg strength. But what about the rest of their body? If we don’t consciously work on core and upper body strength, cycling isn’t going to help there. Have you seen professional cyclists unzip their jerseys? Their upper body looks like a marathoner – skinny and even gaunt. Now, they get paid to be extremely light, but that isn’t necessary for the rest of us and certainly isn’t healthy. We should want balanced strength across our whole body to facilitate functionality as we age. So, we should do other exercises that foster strength above the waist (e.g., rowing, cross-country skiing), or do intentional strength training with weights or body weight, or both!
And what about bone health and density – do you think cycling does anything for that? If anything, cycling may negatively affect bone strength as some cyclists have been diagnosed with osteopenia or osteoporosis. Bone strength results from either impact or stress on the bones from the muscles doing resistance work. Because cycling is not a weight-bearing exercise, our bones don’t get the benefits that a runner does from repetitive impacts. It’s also suspected that the excessive sweating a cyclist does for hours on end may leach calcium from our system, potentially weakening our bones. The solution is to incorporate some ground-based exercises (jumping, running) into your routine or do strength training. Strength training not only helps muscle mass and strength, but when muscles pull on tendons, which pull on bones, that creates stress, signaling the bones to get stronger.
Being fit is not the same as being healthy

And finally, just because we as cyclists can be extremely fit human beings, it doesn’t automatically translate into being extremely healthy. It can, but only if we also live a healthy lifestyle and care for ourselves in other dimensions such as nutrition, cardiovascular health and chronic disease avoidance. For example, because we burn so many calories, we also eat a lot more calories.
If we have a poor diet that means we are eating a lot more low-quality food which can be injurious to our bodies (e.g. highly processed foods). As the saying goes, “You can’t out exercise a bad diet.” I often hear cyclists say that because they ride a lot, they can eat anything. But just because we ride our bikes a lot doesn’t mean our cholesterol, triglycerides and blood sugar numbers are in order. Understand your numbers and address them if they aren’t where they should be. In other words, care for your health as if you didn’t cycle.
All these benefits, aerobic and anaerobic fitness, strength, blood, and body composition, are favorable for living a long and healthy life. On top of all these benefits, cycling is also fun. Many of us do it without even thinking about these health benefits. I certainly didn’t even think of health when I started cycling competitively as a teenager. Although now that I am older, I think about it much more. Unlike some forms of exercise, cycling gets us outdoors, allows us to ride places under our own power, and can be very social.
Bottom line:

Cycling is as close to a fountain of youth as almost anything, but it’s not the complete picture. We need to tap into these other fountains (strength training, nutrition, healthy lifestyle) to round out our health as well as our fitness. So keep this in mind as you are training and riding RAGBRAI. You are doing more good than you may realize.
