At first glimpse this room successful a nondescript portion of Northumbria University looks for illustration a schoolhouse gymnasium, stacked pinch sports equipment.
But why are location labels hanging from nan instrumentality informing to ‘remove earlier launch’ — and what astir that treadmill positioned halfway up nan wall?
Looks tin beryllium deceiving: this isn’t a gymnasium — it’s a testing laboratory for instrumentality designed to amended nan wellness and wellbeing of astronauts.
What’s more, nan instrumentality — and nan penetration being gathered arsenic it’s tested — is group to use our health, too, for conditions ranging from backmost symptom to incontinence.
One instrumentality being developed could beryllium connected a abstraction ngo successful nan adjacent fewer years, but is already being utilized successful an NHS infirmary to velocity up betterment aft knee surgery.
Then there’s that treadmill — its intent is to recreate nan measurement astronauts locomotion successful abstraction to spot really they usage their muscles and joints.

The dream is that examining nan age-type changes successful abstraction will amended our knowing of nan ageing process connected Earth
PhD student Patrick Swain, strapped into a harness connected to pulleys hung from nan ceiling, demonstrates really it useful — astatine nan flick of a move it slow suspends him horizontally successful nan aerial truthful that his feet extremity up connected nan treadmill (see photo, below).
As he lies connected his back, nan treadmill whirrs into life and it abruptly looks arsenic though Patrick is performing nan jumping and hopping movements you spot astronauts return arsenic they locomotion crossed nan moon’s aboveground (although successful his lawsuit he’s doing this lying down).
Longer term, this whitethorn beryllium utilized to place nan champion exercises for those recovering from room who can’t carnivore weight.
You mightiness deliberation location must beryllium easier ways to make advances successful healthcare, but studying astronauts has awesome advantages.
‘Going to abstraction is seen arsenic a bully exemplary of what happens to our muscles and bones during nan earthy ageing process present connected Earth — but up location nan changes hap overmuch quicker,’ explains Nick Caplan, a professor of aerospace medicine and rehabilitation who heads nan Aerospace Medicine and Rehabilitation Laboratory astatine Northumbria.
A self-confessed ‘space nerd’, he specialised successful biomechanics and was investigating ways to amended replacement knees and hips earlier his investigation veered towards space.
‘When astronauts are successful space, their muscles get astir 20 per cent smaller and astir 40 per cent weaker complete nan people of a six-month mission, and their bones suffer density, too, conscionable arsenic erstwhile we property complete nan people of decades present connected Earth,’ he says.
Astronauts suffer 1-2 per cent of nan bony density successful their hips and spine each period — post-menopausal women, aliases older men, suffer it astatine a complaint of 0.5-1 per cent per year.
‘What’s more, whereas group move up astatine nan doctor’s only aft they person anemic bones aliases different age-related conditions, studying astronauts, we tin tally tests connected them earlier and aft these processes happen, and perchance place why these changes happen,’ says Professor Caplan.
The dream is that examining nan age-type changes successful abstraction — which isn’t isolated to nan muscles and bones (more connected this later) will amended our knowing of nan ageing process connected Earth.
It’s an area of gathering liking and finance successful nan UK, which includes nan opening past twelvemonth of nan UK’s first Space Innovation Laboratory.
Based astatine nan Botnar Institute for Musculoskeletal Sciences astatine Oxford University, it has nonstop machine and camera connections pinch nan International Space Station (ISS), which has been orbiting Earth since 2000.
In September, nan UK laboratory will nonstop organoids — miniature versions of quality organs and insubstantial grown from stem cells, successful this lawsuit miniature joints — up to nan abstraction station.
They expect to spot changes that would return spot much than 80 years connected Earth, Dr Ghada Alsaleh, a master successful immunology and rheumatology who heads nan laboratory, told Good Health. The organoids will beryllium location for a month, past brought backmost to Earth truthful nan scientists tin analyse nan changes. Dr Alsaleh will besides beryllium capable to behaviour investigation while they’re successful abstraction by instructing computers connected nan ISS.
The scientists will beryllium looking for changes successful nan fluid and chondroitin, a constituent of cartilage that cushions bones successful joints — their breakdown is nan first measurement to osteoarthritis, nan ‘wear and tear’ arthritis that affects millions successful nan UK.
‘If we tin place nan pathways that lend to this past we whitethorn person a caller target for supplier treatments,’ says Dr Alsaleh.
Her laboratory is already moving connected really they could re-purpose existing drugs, equipped pinch nan knowledge gained from space.
She hopes to nonstop much samples — e.g. immune cells — to undertake akin activity later this year.
The immune strategy besides goes done age-related changes — for example, T-cells go little progressive successful abstraction starring to an accrued susceptibility to infection.
In fact, astir bodily processes are affected — moreover eyesight, arsenic nan deficiency of gravity intends fluid and humor excavation adjacent nan optic nerve, affecting nan sharpness of vision. Meanwhile, nan muscles that power humor vessels go little effective arsenic they nary longer activity against gravity — and nan bosom doesn’t person to pump arsenic hard, truthful wrong days starts to alteration from an oval to a shot style (most changes look to reverse, pinch time, connected return to Earth).
But it’s muscles and bones that possibly return nan biggest deed — aft astronaut Frank Rubio spent 371 days successful space, he had to beryllium lifted from nan spacecraft to forestall him falling arsenic he was truthful weakened by nan mission.
That’s mostly owed to nan deficiency of gravity — which mimics nan effect sedentary lifestyles and ageing has connected america here.
Without realising it, we push against gravity pinch each movement; this builds our muscles while ensuring aged cells get surgery down and stimulating nan accumulation of caller ones.
In space, galore muscles are hardly utilized and nan bones commencement to leach aged bone, calcium and different nutrients, yet nan process to nutrient caller bony cells doesn’t footwear in, explains Professor Caplan.
(A study published successful PLoS One successful 2020 estimated that a 3rd of astronauts would create osteoporosis during a three-year information travel to Mars — putting them astatine consequence of fractures pinch minimal impact.)
‘On Earth, sedentary lifestyles mean we underuse muscles and underload bones,’ says Professor Caplan.
Most of nan activity astatine Northumbria is aimed astatine reducing this musculus nonaccomplishment and nan resulting wellness complaints specified arsenic little backmost symptom — a communal problem for abstraction travellers, and 1 of nan astir communal causes for a sojourn to nan GP successful nan UK.
In fact, immoderate of nan instrumentality being researched astatine Northumbria whitethorn use specified mortals much than it does astronauts.
Take ‘FRED’ (which stands for functional readaptive workout device), which looks for illustration a transverse trainer but is specially adapted to activity conscionable nan muscles astir nan spine and heavy successful nan abdomen. These muscles support nan spine — if they go weakened, it tin lead to stiffness and pain.

FRED, which has been nether improvement since 2009, has been designed to thief astronauts rehabilitate aft abstraction flight.
However, nan squad is hoping to create a type that could beryllium utilized successful clinics aliases GP surgeries.
‘When personification has little backmost pain, nan muscles astir nan little spine go smaller — whether that arises from nan symptom reducing mobility truthful nan muscles are utilized less, aliases because nan messages travelling from nan encephalon to nan muscles becoming dysfunctional varies from personification to person,’ says Kirsty Lindsay, an adjunct professor of rehabilitation sciences who is portion of nan Northumbria team.
The mentation is that strengthening these muscles supports nan spine amended and improves mobility and pain. ‘But it’s difficult to activity these muscles consciously,’ says Dr Lindsay.
Enter FRED: To usage it, you must guidelines upright without holding nan manus supports and slow pedal — dissimilar a normal cross-trainer, location is nary guidance from nan ft plates, truthful you must usage your soul halfway muscles to power nan activity and enactment balanced different your feet rotation round. (As I discovered, it’s each spot arsenic tricky arsenic it sounds). While nan grounds truthful acold suggests it has imaginable for astronauts, a study published successful nan diary Musculoskeletal Science and Practice successful 2020, involving 13 non-astronauts pinch chronic little backmost pain, had much awesome findings.
Participants utilized FRED for up to 15 minutes, 3 times a week, for six weeks.
‘What we found, anecdotally, is that successful immoderate participants, nan magnitude of clip they were successful symptom reduced — but nan astir striking uncovering was that they had dramatically amended activity levels compared to before,’ says Professor Caplan.
‘They were capable to resume hobbies specified arsenic play and gardening, which was retired of nan mobility before. That betterment was maintained erstwhile we saw them again aft six weeks.
‘There aren’t immoderate different workout devices that train these muscles successful nan correct measurement to thief pinch spinal postural control,’ he adds.
This instrumentality that was expected to thief get astronauts connected their feet is besides being tested arsenic a curen for women pinch urinary incontinence post-childbirth.
‘We are conscionable finishing a study to spot whether FRED tin thief nan pelvic level muscles — this could beryllium revolutionary arsenic location hasn’t been overmuch improvement successful this area since 1948,’ says Dr Lindsay.
The study participants completed 12 workout sessions, each up to 30 minutes, complete 4 to six weeks.
‘So acold nan results look encouraging,’ says Dr Lindsay — nan afloat results will beryllium published successful nan adjacent twelvemonth aliases two.
As abstraction missions are galore years successful nan planning, immoderate of nan devices being tested astatine Northumbria whitethorn beryllium utilized connected Earth beforehand.
For instance, a type of a tourniquet that’s wrapped astir a limb to amended nan effect of workout — hopefully owed successful abstraction successful nan adjacent mates of years — is being utilized by an NHS infirmary connected patients aft knee surgery. It’s based connected nan rule of humor travel regularisation exercise, which makes immoderate workout you do much effective.
Luke Hughes, an adjunct professor of abstraction physiology astatine Northumbria, explains: ‘Low-intensity workout is successful itself not effective astatine building musculus and bony — for that, you request higher-intensity guidance [e.g. pinch weights] aliases aerobic workout [which raises nan bosom rate].’
But without gravity to activity against, it’s harder to do high-intensity workout successful space; similarly, low-intensity workout whitethorn beryllium each ‘someone who’s had surgery, aliases who has weakened bony done osteoporosis, for example, tin do’, says Dr Hughes.
The tourniquet is inflated astir a limb — for illustration a humor unit cuff — to a unit individualised to nan wearer. This restricts humor travel — and truthful oxygen travel — to nan muscles, and prevents by-products of exercise, metabolites, being removed, ‘recreating nan conditions that you would get successful nan muscles and different tissues during high-intensity exercise’, says Dr Hughes.
This strengthens musculus and bony pinch minimal movement. Dr Hughes worked pinch a shaper successful Canada to modify a exemplary they had already designed.
In a study, published successful nan diary Sports Medicine successful 2019, he recovered that successful patients who’d had room to repair nan anterior cruciate ligament (ACL) successful nan knee, those who utilized nan tourniquet doubly play while doing low-impact limb exercises had ‘significantly’ little symptom and amended activity and bigger musculus development, compared pinch those who were utilizing dense weights to do limb presses.
As a result, University College London Hospital, wherever nan study was carried out, now uses nan instrumentality for rehabilitation aft knee room (particularly for ACL) pinch low-intensity workout (this besides reduces nan chances of nan diligent injuring themselves again).
Perhaps not surprisingly, Premier League shot clubs person been successful touch pinch Dr Hughes.
Competition to get technological instrumentality connected to tightly packed spacecraft to beryllium tested is truthful fierce that overmuch of nan team’s investigation is done connected Earth successful conditions that mimic debased gravity, specified arsenic successful ‘bed rest’ studies.
These studies are overmuch much arduous than they sound, arsenic volunteers must dishonesty connected their backs connected a tilted bed, their caput beneath nan level of their feet, 24 hours a time for 60 days.
This recreates nan effects of being successful a microgravity environment, wherever humor and different fluid pulls towards nan abdomen and head.
‘You don’t get that compression of nan spine and nan joints which usually happens connected Earth either,’ says Professor Caplan.
It sounds tortuous — ‘it would nonstop maine mad,’ admits Professor Caplan.
Recruits are paid astir £14,000 — ‘apparently they get lawyers who opportunity they’re going to activity connected caseloads — and students revising for exams,’ says Dr Hughes.
Later this twelvemonth nan Northumbria squad will tally a furniture remainder study led by nan European Space Agency successful Slovenia, to spot if location is simply a measurement to spot whether nan measurement personification moves tin foretell nan consequence of processing weakened muscles astir their spine — and backmost pain.
Participants will deterioration reflective markers truthful their movements tin beryllium tracked successful 3D by camera sensors earlier and aft nan enforced ‘rest’.
‘Potentially, we could past create an app linked to wearable tech that would observe erstwhile you aren’t moving wrong nan normal scope to alert you to nan consequence of processing backmost symptom aliases postural instability,’ Professor Caplan says.
There are galore hurdles yet to flooded — not slightest because nan changes successful our bodies successful abstraction are not straightforward.
While galore parts of our assemblage property faster, nan telomeres — nan structures that beryllium connected nan extremity of each strand of our DNA, a spot for illustration nan extremity of a shoelace — that thief protect our genes from damage, unexpectedly get longer during nan flight: usually these shorten pinch age.
Scientists are investigating what it whitethorn mean for longer-term abstraction recreation — and for nan remainder of us.
Even so, Dr Alsaleh says: ‘We’re entering an incredibly breathtaking era, wherever we tin usage our knowledge gained from abstraction to summation nan magnitude of life that we walk successful bully health.’
And who wouldn’t invited that?
