Recovery and Training After 45: Athlete FAQ | ACT 2

Question 1

Does endurance training cause heart disease?

Accepted Answer

No — exercise remains strongly protective for long-term health, and that is not what the MASTER@HEART study showed. The narrower finding is that lifelong high-volume endurance training does not confer the coronary immunity many endurance athletes assume it does: the veteran endurance athletes in that study had more coronary plaque than fit, healthy controls rather than less. The practical consequence is that a long training history is not a reason to skip cardiovascular assessment.

Question 2

Should I get a coronary calcium score?

Accepted Answer

A coronary calcium score may be a reasonable next step depending on your risk profile, family history and what the rest of your picture shows, and it is a decision to make with a clinician rather than a default for every former endurance athlete. ACT 2 Health performs no imaging of any kind, so where a scan is indicated we say so and refer for it.

Question 3

My cholesterol has always been good. Is that enough?

Accepted Answer

A good lipid panel is a genuine positive and it is not the whole picture, particularly in a lean former endurance athlete. Calculated LDL cholesterol is least reliable in exactly that body type, ApoB counts atherogenic particles directly, and Lp(a) is largely genetic and unaffected by anything you did in training. Neither ApoB nor Lp(a) appears on a standard panel, and both are worth having measured at least once. More on both markers.

Question 4

My testosterone came back low. Do I need testosterone therapy?

Accepted Answer

Not necessarily, and a low testosterone reading in a former endurance athlete is the finding most worth slowing down on. Chronic under-fueling suppresses the hormonal axis, so where inadequate energy availability is driving the number, treatment addresses the reading rather than the cause — and in men it can suppress the body's own production further. Establishing why the level is low comes before deciding whether to treat it. More on testosterone.

Question 5

I played in college, not professionally. Does the research on former athletes apply to me?

Accepted Answer

Much of the published research on former collision and team-sport athletes studies professional players at the extreme end of exposure, which is a real limitation and worth stating plainly. The mechanisms it describes — weight carried during the career, collision load, injury history — are the same ones, and the far larger population is people at exactly the college and serious-club level. It makes the findings a reason to ask questions about your own history rather than a prediction about you.

Question 6

I'm back to my college playing weight. Isn't that the goal?

Accepted Answer

Returning to playing weight is a good outcome and it does not appear to erase the trajectory. In former players, the weight carried during the career shows up in midlife findings independently of current weight — so getting back down is worth doing, and treating it as the end of the question is the part worth revisiting. Body composition and function tell you more at this stage than the number on the scale.

Question 7

Why does a clinician keep asking about my sleep?

Accepted Answer

Sleep-disordered breathing is the most commonly missed finding in former collision-sport athletes and the one where treatment changes the most — it drives blood pressure, metabolic markers, mood and daytime fatigue, and it gets filed under getting older. Loud snoring, waking unrefreshed and a collision-sport career together are reason enough to ask about screening. ACT 2 Health screens and refers; we cannot diagnose sleep apnea. More on sleep in midlife.

Question 8

Can ACT 2 Health assess my concussion history or CTE risk?

Accepted Answer

No. Assessing concussion history or the consequences of repetitive head impacts requires in-person neurological examination, which is outside what a telehealth practice can responsibly do. If it is a concern it needs a clinician who can examine you, and it is worth raising rather than living with.

Question 9

My knee has been bad for twenty years. Is that a medical problem or an orthopedic one?

Accepted Answer

Both — and treating a long-standing bad knee as purely orthopedic is how its medical consequences get missed. A joint that limited your activity for two decades is a cardiometabolic exposure in its own right, and it belongs on your medical history rather than only in a physical therapist's notes. ACT 2 Health cannot examine or image the joint; what we can do is measure what the reduced activity did to everything else.

Question 10

Should I be trying to lose weight or build strength?

Accepted Answer

Usually both, with muscle deliberately protected while the weight comes off. The clearest finding in former team-sport athletes is functional rather than metabolic — worse performance on functional testing than recreationally active controls — which makes resistance training the non-negotiable half of the plan. Weight loss achieved by shedding muscle alongside fat makes that finding worse rather than better. More on weight loss.

Question 11

Do I need to tell my clinician about past anabolic steroid use?

Accepted Answer

Yes — it genuinely changes how your hormone results should be read, and withholding it is a common reason a testosterone panel gets misinterpreted in former strength athletes. It is history-taking rather than a judgment, and it does not affect your eligibility for care. What was used, for how long, and how long ago it stopped are all useful.

Question 12

Does ACT 2 Health offer post-cycle therapy or a restart protocol?

Accepted Answer

No. ACT 2 Health does not provide post-cycle therapy, restart protocols, or clomiphene or hCG prescribed for that purpose, and does not prescribe testosterone for performance or physique goals. Where a genuine deficiency exists it is treated as a medical condition, with the evaluation and monitoring that go with that.

Question 13

Can ACT 2 Health do a DEXA scan?

Accepted Answer

No — ACT 2 Health performs no imaging of any kind, including DEXA. Where a formal bone density or body composition assessment is warranted, we say so and refer. What we can do is establish from your history and your labs whether one is indicated, which is often the part that has been skipped.

Question 14

I'm losing strength but my labs are normal. What now?

Accepted Answer

Losing strength on normal labs is a common and important combination, and it usually means the problem is not a hormone level. Age-related loss of muscle mass and power is not primarily a lab finding, and the interventions with the best evidence behind them are progressive resistance training and adequate protein rather than a prescription. A clinician who reaches for a treatment in that situation is treating the wrong thing.

Question 15

Will testosterone therapy get me back to where I was?

Accepted Answer

No, and anyone promising that is selling something. Where a genuine deficiency exists, treating it can improve symptoms — energy, mood, libido, body composition — and that is a worthwhile outcome on its own terms. It does not restore the capacity of a twenty-five-year-old, and expecting it to is the commonest reason people are disappointed by treatment that is otherwise working. More on testosterone.

Question 16

My weight hasn't changed since my twenties. Isn't that good?

Accepted Answer

A weight that has not changed since your twenties is neutral rather than reassuring, because muscle lost and fat gained net out on the scale. That is why weight is the wrong instrument for a strength or power history — composition and function are what changed, and they are what is worth tracking. What you can lift, how fast you can produce force, and how you move tell you more than the number.

Question 17

I stopped competing twenty years ago. Can under-fueling still be affecting me?

Accepted Answer

Yes, particularly for bone, where years of inadequate energy availability appear to leave a durable mark on peak bone mass that later training does not undo. Hormonal effects may or may not have lifted, which is exactly why measuring beats assuming. A training history that outran eating is worth raising decades later, and it is almost never asked about.

Question 18

Does under-fueling only affect women athletes?

Accepted Answer

No — the endocrine suppression caused by inadequate energy availability occurs in men too, and it is both less recognized and less studied. A lean former male endurance athlete with a low testosterone reading is one of the presentations most likely to be misattributed to ordinary age-related decline. The same holds for bone: the under-fueling mechanism affects male bone and is rarely asked about.

Question 19

My periods stopped for years while I was training. Does that matter now?

Accepted Answer

Yes — a history of training-related amenorrhea is one of the most useful things you can tell a clinician in midlife, and one of the least likely to be asked about. It bears directly on bone, because years without menstrual cycles are years without the estrogen exposure that builds and maintains peak bone mass, and it changes how your current hormone results should be read. It is worth raising unprompted, however long ago it was.

Question 20

Will treating my hormones fix under-fueling?

Accepted Answer

Probably not, if inadequate fueling is what is driving the numbers. Treating the hormone level in that situation addresses the reading rather than the cause, and in men it can suppress the body's own production further. What works is restoring adequate energy availability, which is a nutrition and training-load question before it is a prescription.

Question 21

Does ACT 2 Health treat eating disorders?

Accepted Answer

No. If disordered eating is part of the picture, ACT 2 Health will say so and refer — it needs specialist care rather than a lab panel, and a former athlete's relationship with food and training is a common place for it to hide. Declining to treat it is not the same as declining to take it seriously.

Question 22

Is most of the research on former athletes really done on men?

Accepted Answer

Yes. In the 2023 BMJ Open Sport & Exercise Medicine scoping review of midlife former athletes, twelve of the twenty studies evaluated males only, and just four included female participants exclusively — two of those with fewer than fifty people in total, controls included. The largest study of lifelong endurance athletes' coronary health was entirely male. Much of what is said confidently about former athletes is, on inspection, said about former male athletes.

Question 23

I was a gymnast, dancer or distance runner. Are my bones protected?

Accepted Answer

Possibly protected and compromised at once, which is why the blanket reassurance usually given is unhelpful. High-impact loading protects the skeleton that was loaded, and that protection is site-specific rather than general. A history of low energy availability or of periods stopping can take some of it back. Which applies to you is measurable rather than assumable.

Question 24

I'm tired all the time and my thyroid was normal. What else is worth checking?

Accepted Answer

Ferritin and full iron studies, vitamin B12, and a proper look at where you are in the menopausal transition are the usual next steps after a normal thyroid result. Iron is frequently the missing piece in women with heavy bleeding, and ferritin is not on most standard panels — it has to be asked for. Fatigue that does not respond to sleep deserves a wider panel rather than a repeat of the same one. More on fatigue.

Question 25

Does cycling build bone?

Accepted Answer

No — cycling is non-impact and does not deliver the mechanical loading that builds bone, which surprises people with decades of serious riding behind them. It is an excellent cardiovascular history and it is not a bone history. If your training has been predominantly non-impact, impact and resistance loading are worth adding deliberately rather than assuming the volume covered it.

Question 26

Should I get a DEXA scan at 45?

Accepted Answer

A DEXA scan may be warranted earlier than the usual screening age if you have a history of low energy availability, of periods stopping during training, a predominantly non-impact sport background, a previous fracture, or a family history of osteoporosis. Standard screening guidelines were not written with that history in mind. ACT 2 Health cannot perform one and refers where it is indicated.

Question 27

Can supplements fix low bone density?

Accepted Answer

Correcting a genuine deficiency helps — vitamin D or calcium intake that is actually inadequate is worth putting right. Supplementing on top of adequate status does not build bone. What builds bone is mechanical loading and adequate fueling, and where density is genuinely low that is a clinical conversation about treatment rather than a supplement question.

Question 28

Why would an old knee injury affect my heart?

Accepted Answer

Not directly — the route is behavioral. An injury that reduced your physical activity for decades is a cardiometabolic exposure, and the Harvard study of former football players found that those with ACL tears carried increased heart attack risk alongside the expected joint outcomes. The useful question about an old injury is not whether the tissue healed, but what your activity looked like in the years afterward and whether it ever came back.

Question 29

Can ACT 2 Health treat my joint pain?

Accepted Answer

No. ACT 2 Health cannot examine you, image you or assess a joint, so joint pain needs a clinician who can — physical therapy, sports medicine or orthopedics. An old injury that still limits how you move, swells, gives way or wakes you at night deserves current assessment, and because exercise is strongly recommended for knee and hip osteoarthritis, a diagnosis is usually a route back to training rather than away from it. What we can measure is what the reduced activity did to everything else.

Question 30

Will peptides heal my tendon?

Accepted Answer

The evidence that peptides heal tendon is thinner than the marketing suggests, and much of what is cited for tissue repair is preclinical rather than human. Peptides prescribed for recovery are compounded preparations that are not FDA-approved and are not equivalent to any branded product. The honest answer for most midlife tendon problems is load management, progressive rehabilitation and time. Individual compounds are covered in peptides by name.

Question 31

I've been in pain for years and just got on with it. Is that a problem?

Accepted Answer

Yes — it may be the single biggest modifiable risk in this population, and the risk is not the pain itself but the trained habit of working through things that should have prompted a conversation. Athletic culture teaches you to treat symptoms as discipline problems, which is why former athletes arrive late. New chest pain or pressure, unusual breathlessness, palpitations, dizziness or fainting during exercise are the ones to stop for rather than push through.

Question 32

I gained weight quickly after I stopped training. Why?

Accepted Answer

The usual explanation is mechanical: the eating patterns built around a heavy training load stayed after the load left, and a large training volume is easy to underestimate once it is gone. It is common, it is not a character failure, and it is addressable. Weight gained this way often comes with muscle loss underneath it, which is why composition matters more than the scale here. More on weight loss.

Question 33

Do anti-doping rules apply to masters and age-group athletes?

Accepted Answer

Yes, if your events are sanctioned by a World Anti-Doping Code signatory. USADA's definitions treat masters and age-group classifications as distinct from elite competition rather than exempt from the system, so the rules that bind a professional bind you at a sanctioned masters event. The trigger is how the event is sanctioned, not how seriously you take it.

Question 34

Is a doctor's prescription a defense against an anti-doping violation?

Accepted Answer

No. A clinically appropriate prescription for a prohibited substance still requires an approved Therapeutic Use Exemption — that is the entire purpose of the TUE process. Testosterone therapy, several peptides and a number of everyday medications are prohibited in sport, so anyone still competing needs to check before starting treatment rather than after.

Question 35

Can ACT 2 Health get me a therapeutic use exemption?

Accepted Answer

No — the obligation to apply for a TUE sits with you as the athlete. Your prescriber can supply the medical documentation an application requires, but the exemption itself is applied for and granted through your anti-doping organization. Tell us you compete when you complete the assessment, and run the USADA Pre-Check, before anything is prescribed rather than after.

Question 36

Is DHEA prohibited in sport?

Accepted Answer

Yes — DHEA is prohibited under the World Anti-Doping Code, and its over-the-counter availability in the United States has no bearing on that. It sits on pharmacy and supermarket shelves, which catches competing athletes out regularly. Anything you take, prescribed or not, needs checking against the prohibited list if you compete under a Code signatory.

Question 37

Why do I recover more slowly than I did as an athlete?

Accepted Answer

Several things change at once: less sleep, more life stress, less muscle mass, old injuries, and a muscle-building response to protein that declines with age. Recovery is a repair process, and most of that repair happens during sleep, which tends to get lighter and more fragmented in midlife. Slower recovery is expected; pain that does not settle, or a sudden change in what you can do, is not, and deserves assessment rather than more rest days.

Question 38

How much protein does a former athlete over 45 need?

Accepted Answer

More than the standard adult recommendation, because the muscle-building response to protein declines with age — the PROT-AGE Study Group recommends that older adults who exercise aim above the general adult target, and a 2018 meta-analysis found extra protein improved strength and muscle gains from training, with the benefit smaller with age and plateauing beyond a point. Spreading protein across meals, including one after training, matters more than any single large serving. A clinician can set the actual target for your body weight and kidney function; if you have kidney disease, check before raising protein at all.

Question 39

Do ice baths help recovery after lifting?

Accepted Answer

Cold water immersion may feel good, but for strength training it appears to work against the adaptation you are training for: in a 2015 study in The Journal of Physiology, men who used cold water immersion after twice-weekly strength sessions for twelve weeks gained less strength and muscle than men who did an active cool-down. The participants were young, so apply the finding with care. If you enjoy cold exposure, schedule it away from lifting days rather than straight after them.

Question 40

Do recovery peptides work?

Accepted Answer

Peptides marketed for recovery run well ahead of the research behind them, long-term human data is limited, and for several of the compounds in circulation the evidence is preclinical. Peptides prescribed for recovery are compounded preparations that are not FDA-approved and are not equivalent to any branded product, and some are prohibited in sport. Where recovery has genuinely slowed, establishing why — sleep, iron, thyroid, hormones, fueling — is more productive than adding a compound on top of an unanswered question.
