Competing over 35: what actually changes
Masters brackets are among the largest fields in combat sport, and almost nothing is written for them. What does exist is mostly advice for sedentary older adults, handed to people who train 4 times a week and compete.
Your daily protein target is the same as a younger competitor’s. The research behind the claim that you need far more was done on untrained older adults, and the anabolic resistance it describes is driven by inactivity rather than by age.
What shifts slightly is the size of each sitting.
What does appear to change is recovery from damaging work, which is slower.
Masters brackets use the same weight limits as the adult divisions, so a 45-year-old cuts to the same number with less capacity to recover from it.
And the one nobody mentions: at this age you are far more likely to be taking a prescribed medication, and some common ones are prohibited. Asthma inhalers are permitted but carry dose limits, and some blood pressure tablets are diuretics.
What the protein research actually says
The claim you will meet everywhere is that older athletes need substantially more protein, because ageing muscle responds less to a given dose.
That effect is real, and it was measured in older adults who were not training.
A second group carries the same medication risk for a different reason, and that case is in heavyweights.
A masters athlete is also close enough to the end of competing that what happens afterwards is worth planning now.
For a female competitor the picture changes again in her forties, because the signal she has relied on for years stops being reliable: female athletes over 40.
A 2021 review in Sports Medicine put the counter-argument directly: masters athletes have body composition, muscle characteristics and responses to exercise closer to trained young adults than to their sedentary peers, and the physiological changes underlying anabolic resistance are precipitated by inactivity.
Its conclusion was that the recommendations for younger trained adults apply.
The same target as any competing athlete: roughly 1.6 to 2.0 grams of protein per kilogram of body mass a day, and toward the upper end while reducing weight.
Distribution is worth attending to as a refinement, though the daily total still matters more. Where a younger athlete maximises the response at around 0.3 g per kilogram in a sitting, the figure for a competitor past 35 is closer to 0.4 g per kilogram, which for an 80 kg athlete is roughly 32 grams.
Four sittings of that rather than one large one and three small.
Note the shape of that advice. The daily figure does not move, and most of what changes is how the same food is arranged across the day.
That is a considerably cheaper problem to solve than the one people expect to have.
The numbers behind the ageing
Most of what gets said to masters competitors is either flattery or a warning. The measured picture comes from reviews of ageing in trained athletes, and it is more encouraging than either.
The measured picture is more useful than either, and it is more encouraging than people expect.
| What | Rate of change | What it means in practice |
|---|---|---|
| Aerobic capacity | Roughly 5 to 12 percent per decade, even in athletes who keep training | Absolute values stay far above sedentary peers of the same age |
| Muscle mass | Around 5 percent per decade, and slower in trained athletes than untrained | Training does not stop the decline but it substantially slows it |
| Power | Around 8 percent per decade | Falls faster than maximum strength, which is the finding that matters most here |
Read the last row against what this sport asks for. Power declines faster than strength does, and a fighter is a power athlete rather than a strength athlete.
That gap explains more about how a masters competitor's performance changes than any single number.
The second finding worth having is about recovery rather than capacity. The evidence is more limited, but it points consistently in one direction: recovery after high-intensity and muscle-damaging work takes longer past about 40 to 45, with creatine kinase and force production returning to baseline more slowly.
The problem is rarely that a masters athlete cannot do the session. It is that he cannot do the session, then do the next one on the same schedule he used at 25.
The recovery window has lengthened while the training week has not, and that mismatch is where masters competitors get injured and stale.
There is also anabolic resistance: the muscle-building response to both protein and training is blunted with age, so the same intake produces less. That is the reason the protein guidance in the section above sits at the upper end of the range rather than the middle.
What does change
Recovery from damage
Where the evidence points to a real difference is repair. In one comparison of masters and younger triathletes after a deliberately damaging session, the older group showed lower rates of muscle protein synthesis and a tendency toward reduced performance across the following 3 days.
Applied to combat sport, the session that damages you is sparring. Which means the number of hard rounds in a week, and the spacing between them, matters more at 40 than at 20. Not the training itself. The gaps.
The calendar you actually have
This is the part nobody writes about because it is not physiology. A masters competitor usually trains around a job, often around children, and sleeps less than the training load deserves.
Sleep is where most of the repair happens, and it is the variable most often surrendered. A competitor at this age who sleeps 6 hours because of work is carrying a recovery deficit that no supplement addresses, and it will show up as a plateau that gets blamed on age.
The weight cut question
Masters divisions generally use the same weight limits as the adult categories. In jiu-jitsu that is explicit across the masters brackets, and the arrangement is similar elsewhere.
So the rules ask a 45-year-old to reach the same number as a 25-year-old, from a body that repairs more slowly and often with less time to prepare.
The published ceiling for an acute cut stays the same at any age; the cost of approaching it rises.
Practically, that argues for the same thing this site argues for at every age, only more strongly: choose a division you can hold rather than one you can reach. The arithmetic is in which division you belong in, and if the answer is the class above, moving up usually costs nothing at all.
In jiu-jitsu you weigh in minutes before your first match, so there is no recovery window to lean on. In a tournament format you weigh in every morning while competing.
Neither of those forgives a hard cut at any age, and both punish it more when repair is slower.
The formats are compared in BJJ and in judo, wrestling and amateur boxing.
Bone, and why it is a masters question
Bone density declines with age, and repeated cycles of weight reduction over years are one of the things that work against it. A competitor who has been cutting since his twenties and is still cutting at 45 has a long exposure behind him.
It is silent while it happens and it reports late. Calcium and vitamin D intake, and enough energy to support the training, are the levers that exist, and the wider case is in bone health, which applies to male masters athletes as well as to the audience it was written for.
The medicine cabinet
This is the section I would put in front of every masters competitor, and I have never seen it written anywhere.
At this age you are far more likely to be taking something prescribed. Blood pressure medication is the common one, and several widely prescribed treatments for hypertension are thiazide diuretics, which are prohibited at all times under the WADA Code as masking agents. They are prohibited whether or not you took them to lose weight and whether or not your doctor knew you compete.
Loop diuretics are prohibited on the same basis, as are combination products that contain a diuretic alongside another blood pressure agent.
Some treatments for asthma, for attention disorders and for hormonal conditions sit on the List as well.
Beta blockers are worth a separate word, because they are widely misunderstood. They are prohibited only in a specific set of precision sports such as shooting, archery, darts and golf. Combat sports are not on that list, so a competitor taking one for a cardiac reason is generally not taking a prohibited substance.
Confirm it for your own sport rather than assuming either way.
Check every prescription and every over-the-counter product against the current Prohibited List, and do it now rather than after an event. Where a prohibited medication is genuinely needed, the route is a therapeutic use exemption, applied for in advance through the relevant authority.
Tell the prescribing doctor that you compete in a tested sport. Most will not think to ask, and it is not their job to know the List.
Whether your competition is tested at all depends on the organisation, and the general picture is in who actually tests you. The absence of testing at one event is not a reason to be relaxed: the record follows the athlete rather than the card.
What I would tell a masters competitor
- Keep the daily protein target where a younger athlete keeps it, and take it in four sittings of around 0.4 g per kilogram rather than two large ones.
- Count hard sparring rounds per week, and protect the gaps between them more carefully than the sessions themselves.
- Treat sleep as part of the plan rather than as what is left over.
- Choose the division you hold, not the one you reach. At this age the cut costs more and returns less.
- Check every medication against the Prohibited List, and tell your doctor you compete.
The advantage nobody mentions
Masters competitors are, on the whole, the best-organised athletes I work with. They plan, they turn up, they do what was agreed, and they do not experiment 2 days before a competition.
That is worth more than the physiology costs. The 45-year-old who eats properly, sleeps as much as his life allows, and competes at a weight he actually holds will beat the version of himself who tried to train like he did at 25, and he will still be competing when that version has stopped.
