Everyone knows that biking is a ticket to higher well being, regardless 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 finally catches up with us. What are the modifications going down 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 find out how to hold striving to remain at our greatest regardless of what number of candles on the birthday cake.
The phrase ‘age is only a quantity’ is bandied round lots, however as I strategy my fortieth birthday – a prospect that considerations quite 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 will be achieved to sluggish 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-Nineteen 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 charge of oxygen uptake of the cardiovascular system – the center and lungs fuelling the muscle groups – throughout train, VO2 max is considerably genetically decided, will be improved by 10-20% by means of coaching, and declines with age. For well-trained cyclists, this decline tends to be sluggish (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 basically 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 practical dimension and mass of your left ventricle.” When does the center start to shrink and lose energy? “In case you take a inhabitants of 20,000 folks and plot age in opposition to VO2 max,” says Pringle, “you will notice an enormous lower from 35-40 years previous onwards, however that’s the common of the inhabitants – not educated athletes and individuals who frequently do endurance train.”
It’s reassuring to know that, for us as cyclists, VO2 max declines solely slowly, supplied we proceed to coach persistently. Personally, I’m but to note a lower in efficiency. If my energy numbers are down, I blame an absence of using and life stresses. After I’m disciplined in my health, my energy and ‘snappiness’ returns. I’m conscious, although, that now I’m almost 40, my VO2 max might drop fairly dramatically if I had been to take a chronic break from using.
Muscle 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 will lose muscle mass and muscle operate,” confirms Pringle, “however if you happen to’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 essential.

Coaching our muscle groups may also help decelerate the decline and forestall accidents. Biking itself is, in fact, a type of resistance coaching for the legs – notably on the numerous brief, sharp hills generally discovered within the UK. Nevertheless, biking is ‘one-dimensional’ in that it really works solely sure muscle groups in a single course so it’s not adequate by itself. “As we age, we lose mass inexorably,” explains Professor Stephen Harridge, a professor of human and utilized physiology at King’s Faculty, London. “Power coaching and resistance train turn out to be actually essential. It’s the simplest manner of retaining your muscle operate, energy and energy. With out supplementing your endurance actions with devoted energy and resistance coaching, core and practical energy will decline.”

A twice-weekly, 45-minute routine of body-weight workouts resembling pull-ups, planks and push-ups, which work quite a lot of muscle groups, together with the core, chest, arms and again, is definitely carried out at dwelling. 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 resembling operating, leaping or resistance workouts if they’re to be prevented from weakening.”
Financial system and effectivity
One upside from ageing is the potential for improved financial system and effectivity. Our bodily energy and capability might lower however our our bodies proceed to get craftier in conserving vitality. “By effectivity, we imply how a lot vitality and oxygen the muscle groups want for an quantity of labor,” Jamie Pringle explains. “Though your engine dimension would possibly lower, your miles per gallon would possibly get higher. For an endurance athlete, this acquire 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 whereas explosivity would possibly diminish, possessing base health may also help us maintain greater energy numbers for longer, whilst we age. That is what makes time trialling an awesome choice for older riders who need to keep aggressive.
Restoration and resilience
One other physiological element that modifications as we age is restoration. At any age, coaching stimulus gives stress to the physique, which wants time to recuperate as a way to adapt. As we age, modifications at a mobile stage imply we’d like longer between classes or races to recuperate in order to be prepared for our subsequent journey or race. Ranges of recovery-boosting hormones resembling testosterone and human development hormone additionally fall away.

Does taking longer to recuperate additionally imply harm is extra probably? “Reasonably than being extra prone to harm, you could discover it more durable to recuperate as shortly from harm as you age,” says Pringle. “You don’t bounce again as quick. Conversely, if issues like response instances and steadiness worsen, you could turn out to be extra crash-prone. And naturally, declining muscle mass and subsequent energy discount might 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 weight-reduction plan. These are ideas each bicycle owner ought to observe, however as we turn out to be bodily much less resilient with age, they turn out to be ever extra essential.
Accepting your age
From chatting with 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 had been 10 years in the past or now not beating a lot youthful riders up climbs ought not matter. As we grow old, efficiency ought to be judged in relation to our personal age group. “Many athletes wrestle to come back to phrases with this and struggle 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 finally get slower, lose some explosive energy and want extra restoration time between exhausting 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 larger high quality of life. “Train, health and its well being advantages are what give us larger energy, energy and performance reserves,” concludes Harridge. “This provides us larger independence and a greater high quality of life. It’s about healthspan not lifespan. Who desires to dwell for years in a poor state of well being? The actual query ought to be: how lengthy are you able to be wholesome, practical, impartial, energetic and having fun with life?”

What variations have you ever seen in your racing efficiency as you’ve grown older?
Having misplaced some explosiveness, I race differently. Now I attempt to get away earlier than the climbs to get a spot. You study to make use of your strengths otherwise. You may hold bettering your sustainable energy, FTP and repeatability 12 months on 12 months if you happen to practice persistently. Repeatability and fatigue resistance is important within the third hour of races.
How has your restoration modified?
It’s actually slowing down. Nowadays, 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. After I was youthful, I might do a light-weight restoration spin on Monday and be able to race once more by Tuesday. I bounced again faster. As you age, you may nonetheless do the identical excessive quantity however you would possibly substitute one or two exhausting classes for longer endurance rides.
Have you ever seen comparable developments in your coached riders?
Sure, my youthful riders bounce again a lot sooner. A rider aged 35-40 takes longer to rebuild health after a break. Then once more, riders of my age most likely haven’t received as busy a social life as youthful riders. I used to exit much more and revel in a couple of drinks after a race. I don’t try this as a lot now, so restoration is simpler. Sleep too is so essential for well-being and vitality ranges.
Do you do health club 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 along with your youthful years?
I feel 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 finally 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 get pleasure from coaching and racing, and I do know I received’t be capable to do it ceaselessly. It’s good whenever you will be in a break and be aggressive, and I would like this to go on so long as attainable.
Any recommendation for older riders?
Consistency. As you grow old, it will get more durable to come back again from a break. Preserve doing these exhausting explosive eff orts, VO2 intervals, anaerobic eff orts together with longer endurance rides. In case you cease doing these for one or two seasons, it’ll be exhausting to get again to your stage. After 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 part earlier than getting again into it. For a rider of their 40s or 50s, it will take three or 4 months to get again to regular fi tness after a twomonth break.
