Everyone knows that biking is a ticket to raised well being, irrespective of your age. Whether or not you’re a younger racer chasing glory or a seasoned rider whose racing days are behind you, the bike is a boon mentally and bodily. However for these of us nonetheless pushing the bounds – whether or not in races or simply lengthy rides with our mates – there’s no escaping the reality: age ultimately catches up with us. What are the adjustments happening inside our our bodies because the years roll by, and the way do they have an effect on our biking efficiency? Let’s discover what ageing actually means for a bicycle owner and easy methods to hold striving to remain at our greatest irrespective of what number of candles on the birthday cake.
The phrase ‘age is only a quantity’ is bandied round so much, however as I strategy my fortieth birthday – a prospect that issues relatively than excites me – I need to perceive the physiological results of ageing. How lengthy can I proceed chasing Strava segments, climbing mountain passes, and placing in high-intensity coaching classes? When and why does biking efficiency start to deteriorate, and what might be finished to gradual the inevitable drop-off? My quest to find the reality calls on the experience of train physiologists and an elite rider nonetheless competing in his late-40s.
The max issue
Standout stats
4.3 ml/kg/min: common decline in VO2 max per decade past the age of
30 54%: Proportion of aggressive male cyclists proven in research to have low bone mineral density for his or her age
3-8%: Lack of muscle mass per decade past the age of 30 (considerably slower amongst those that strength-train)
8: Years longer life lived by former Tour de France riders (who competed Nineteen Thirties-Sixties), on common, in comparison with gene
As a barometer of endurance health and efficiency, VO2 max is extensively thought to be the gold commonplace. Outlined as the utmost fee of oxygen uptake of the cardiovascular system – the guts and lungs fuelling the muscle mass – throughout train, VO2 max is considerably genetically decided, might be improved by 10-20% via coaching, and declines with age. For well-trained cyclists, this decline tends to be gradual (and non-linear) – lower than 5ml/kg/ min per decade from the age of 30, however from about 35 the decline is inexorable.
“As VO2 max is essentially pushed by cardiac output, it’s depending on how a lot oxygen the left ventricle pumps per beat,” explains Jamie Pringle, an train physiologist on the College of Birmingham. “So once we’re coping with ageing, we’re coping with a discount in cardiovascular operate, a lack of purposeful measurement and mass of your left ventricle.” When does the guts start to shrink and lose energy? “Should you take a inhabitants of 20,000 individuals and plot age in opposition to VO2 max,” says Pringle, “you will note an enormous lower from 35-40 years outdated onwards, however that’s the typical of the inhabitants – not educated athletes and individuals who recurrently do endurance train.”
It’s reassuring to know that, for us as cyclists, VO2 max declines solely slowly, offered we proceed to coach persistently. Personally, I’m but to note a lower in efficiency. If my energy numbers are down, I blame a scarcity of using and life stresses. Once I’m disciplined in my health, my energy and ‘snappiness’ returns. I’m conscious, although, that now I’m almost 40, my VO2 max may drop fairly dramatically if I have been to take a chronic break from using.
Muscular tissues and bones
Although we’d be capable to stave off the steep discount in VO2 max, there are different bodily elements that additionally start to say no with age. The lack of muscle mass – sarcopenia, to make use of the technical time period – happens at 3-5% per decade from the age of about 30. “You’ll lose muscle mass and muscle operate,” confirms Pringle, “however in case you’re beginning at the next stage with good muscle mass, you’re going to have additional to fall and be in a greater place.” In different phrases, energy coaching turns into more and more vital.

Coaching our muscle mass may help decelerate the decline and forestall accidents. Biking itself is, after all, a type of resistance coaching for the legs – significantly on the various brief, sharp hills generally discovered within the UK. Nonetheless, biking is ‘one-dimensional’ in that it really works solely sure muscle mass in a single course so it’s not enough by itself. “As we age, we lose mass inexorably,” explains Professor Stephen Harridge, a professor of human and utilized physiology at King’s School, London. “Energy coaching and resistance train develop into actually vital. It’s the best approach of retaining your muscle operate, energy and energy. With out supplementing your endurance actions with devoted energy and resistance coaching, core and purposeful energy will decline.”

A twice-weekly, 45-minute routine of body-weight workout routines equivalent to pull-ups, planks and push-ups, which work a wide range of muscle mass, together with the core, chest, arms and again, is definitely carried out at residence. Together with body-weight work, squats, lunges and deadlifts, utilizing weights, construct energy and energy, serving to to take care of muscle mass and enhance explosivity on the bike. Professor Harridge additionally recommends weekly jogging or skipping. “As wholesome as biking is, the truth that it’s a low-impact exercise signifies that it’s not good for sustaining our bone density,” he cautions. “Bones want impactful loading actions equivalent to working, leaping or resistance workout routines if they’re to be prevented from weakening.”
Economic system and effectivity
One upside from ageing is the potential for improved economic system and effectivity. Our bodily energy and capability might lower however our our bodies proceed to get craftier in conserving power. “By effectivity, we imply how a lot power and oxygen the muscle mass want for an quantity of labor,” Jamie Pringle explains. “Though your engine measurement may lower, your miles per gallon may get higher. For an endurance athlete, this achieve considerably makes up for the losses. Case research have proven that older well-trained runners are extra environment friendly than youthful counterparts – it’s related not simply with age however coaching historical past too.”
This feeds into the concept that whereas explosivity may diminish, possessing base health may help us maintain increased energy numbers for longer, whilst we age. That is what makes time trialling an excellent choice for older riders who need to keep aggressive.
Restoration and resilience
One other physiological element that adjustments as we age is restoration. At any age, coaching stimulus supplies stress to the physique, which wants time to get better with the intention to adapt. As we age, adjustments at a mobile stage imply we want longer between classes or races to recuperate in order to be prepared for our subsequent experience or race. Ranges of recovery-boosting hormones equivalent to testosterone and human development hormone additionally fall away.

Does taking longer to get better additionally imply harm is extra probably? “Slightly than being extra vulnerable to harm, you could discover it tougher to get better as rapidly from harm as you age,” says Pringle. “You don’t bounce again as quick. Conversely, if issues like response occasions and steadiness worsen, you could develop into extra crash-prone. And naturally, declining muscle mass and subsequent energy discount may make restoration from harm take longer.”
No matter age, the important thing ideas for maximising restoration stay getting sufficient good high quality sleep – ideally six to eight hours per night time, and consuming a wholesome balanced food plan. These are ideas each bicycle owner ought to observe, however as we develop into bodily much less resilient with age, they develop into ever extra vital.
Accepting your age
From talking to specialists, a key message emerged: whereas we might decline bodily with age, as cyclists we’re nonetheless among the many fittest members of society. Being barely slower than we have been 10 years in the past or now not beating a lot youthful riders up climbs ought not matter. As we become older, efficiency must be judged in relation to our personal age group. “Many athletes wrestle to come back to phrases with this and combat it,” says Harridge, “however they’re combating inevitability. It’s not a criminal offense, you’re not doing something flawed, it’s simply how it’s.”
All of us – even Tadej Pogačar and Wout van Aert – will ultimately get slower, lose some explosive energy and wish extra restoration time between onerous rides. However the well being advantages that biking brings are monumental, and whereas we might not defi nitely dwell longer than non-exercisers, we’re more likely to be more healthy and have a better high quality of life. “Train, health and its well being advantages are what give us better energy, energy and performance reserves,” concludes Harridge. “This provides us better independence and a greater high quality of life. It’s about healthspan not lifespan. Who needs to dwell for years in a poor state of well being? The true query must be: how lengthy are you able to be wholesome, purposeful, impartial, lively and having fun with life?”

What variations have you ever observed in your racing efficiency as you’ve grown older?
Having misplaced some explosiveness, I race otherwise. Now I attempt to get away earlier than the climbs to get a spot. You study to make use of your strengths in a different way. You may hold bettering your sustainable energy, FTP and repeatability yr on yr in case you practice persistently. Repeatability and fatigue resistance is significant within the third hour of races.
How has your restoration modified?
It’s definitely slowing down. Today, if I’ve a tough race on Sunday, I’ll nonetheless be feeling it on Monday and Tuesday, and doubtless received’t do a tough session till Wednesday. Once I was youthful, I’d do a lightweight restoration spin on Monday and be able to race once more by Tuesday. I bounced again faster. As you age, you’ll be able to nonetheless do the identical excessive quantity however you may substitute one or two onerous classes for longer endurance rides.
Have you ever observed related traits in your coached riders?
Sure, my youthful riders bounce again a lot quicker. A rider aged 35-40 takes longer to rebuild health after a break. Then once more, riders of my age most likely haven’t acquired as busy a social life as youthful riders. I used to exit much more and revel in just a few drinks after a race. I don’t try this as a lot now, so restoration is simpler. Sleep too is so vital for well-being and power ranges.
Do you do gymnasium work too?
I’ve osteoporosis, so I attempt to. As I’ve an underlying again harm, I attempt to do three classes every week within the winter: free weights, squats, and walks with a weighted jacket.
How does your present VO2 max examine together with your youthful years?
I believe I’m an outlier as a result of mine has stayed excessive. It’s nonetheless within the mid-70s [ml/kg/min] – barely any decrease than it was within the mid-Nineties. I’m certain it can decline ultimately however not but!
Do you are concerned about bodily declining?
Sure I do! That’s most likely why I practice with extra self-discipline than after I was youthful. I actually take pleasure in coaching and racing, and I do know I received’t be capable to do it without end. It’s good once you might be in a break and be aggressive, and I need this to go on so long as doable.
Any recommendation for older riders?
Consistency. As you become older, it will get tougher to come back again from a break. Hold doing these onerous explosive eff orts, VO2 intervals, anaerobic eff orts together with longer endurance rides. Should you cease doing these for one or two seasons, it’ll be onerous to get again to your stage. Once I coach older riders, I have a tendency to present them a shorter end-of-season break. It’ll be extra of a ticking-over upkeep section earlier than getting again into it. For a rider of their 40s or 50s, it might take three or 4 months to get again to regular fi tness after a twomonth break.
