At first look this room in a nondescript a part of Northumbria College appears like a faculty gymnasium, stacked with sports activities tools.
However why are there labels hanging from the tools warning to ‘take away earlier than launch’ — and what about that treadmill positioned midway up the wall?
Appears to be like will be deceiving: this isn’t a gymnasium — it’s a testing laboratory for tools designed to enhance the well being and wellbeing of astronauts.
What’s extra, the tools — and the perception being gathered because it’s examined — is about to learn our well being, too, for situations starting from again ache to incontinence.
One system being developed might be on an area mission within the subsequent few years, however is already being utilized in an NHS hospital to hurry up restoration after knee surgical procedure.
Then there’s that treadmill — its function is to recreate the best way astronauts stroll in area to see how they use their muscle mass and joints.

Astronauts lose 1-2 per cent of the bone density of their hips and backbone every month
The hope is that inspecting the age-type adjustments in area will enhance our understanding of the ageing course of on Earth
PhD pupil Patrick Swain, strapped right into a harness related to pulleys hung from the ceiling, demonstrates the way it works — on the flick of a swap it slowly suspends him horizontally within the air in order that his ft find yourself on the treadmill (see picture, under).
As he lies on his again, the treadmill whirrs into life and it all of the sudden appears as if Patrick is performing the leaping and hopping actions you see astronauts take as they stroll throughout the moon’s floor (though in his case he’s doing this mendacity down).
Long run, this can be used to establish the perfect workout routines for these recovering from surgical procedure who can’t bear weight.
You may suppose there should be simpler methods to make advances in healthcare, however learning astronauts has main benefits.
‘Going to area is seen as mannequin of what occurs to our muscle mass and bones throughout the pure ageing course of right here on Earth — however up there the adjustments occur a lot faster,’ explains Nick Caplan, a professor of aerospace medication and rehabilitation who heads the Aerospace Drugs and Rehabilitation Laboratory at Northumbria.
A self-confessed ‘area nerd’, he specialised in biomechanics and was investigating methods to enhance substitute knees and hips earlier than his analysis veered in the direction of area.
‘When astronauts are in area, their muscle mass get about 20 per cent smaller and about 40 per cent weaker over the course of a six-month mission, and their bones lose density, too, simply as once we age over the course of many years right here on Earth,’ he says.
Astronauts lose 1-2 per cent of the bone density of their hips and backbone every month — post-menopausal girls, or older males, lose it at a fee of 0.5-1 per cent per 12 months.
‘What’s extra, whereas individuals flip up on the physician’s solely after they’ve weak bones or different age-related situations, learning astronauts, we will run assessments on them earlier than and after these processes occur, and doubtlessly establish why these adjustments occur,’ says Professor Caplan.
The hope is that inspecting the age-type adjustments in area — which isn’t remoted to the muscle mass and bones (extra on this later) will enhance our understanding of the ageing course of on Earth.
It’s an space of gathering curiosity and funding within the UK, which incorporates the opening final 12 months of the UK’s first House Innovation Laboratory.
Based mostly on the Botnar Institute for Musculoskeletal Sciences at Oxford College, it has direct pc and digicam connections with the Worldwide House Station (ISS), which has been orbiting Earth since 2000.
In September, the UK lab will ship organoids — miniature variations of human organs and tissue grown from stem cells, on this case miniature joints — as much as the area station.
They anticipate to see adjustments that may happen greater than 80 years on Earth, Dr Ghada Alsaleh, a specialist in immunology and rheumatology who heads the laboratory, informed Good Well being. The organoids will probably be there for a month, then introduced again to Earth so the scientists can analyse the adjustments. Dr Alsaleh will even be capable of conduct analysis whereas they’re in area by instructing computer systems on the ISS.
The scientists will probably be searching for adjustments within the fluid and chondroitin, a element of cartilage that cushions bones in joints — their breakdown is step one to osteoarthritis, the ‘put on and tear’ arthritis that impacts tens of millions within the UK.
‘If we will establish the pathways that contribute to this then we might have a brand new goal for drug therapies,’ says Dr Alsaleh.
Her lab is already engaged on how they might re-purpose present medication, armed with the information gained from area.
She hopes to ship extra samples — e.g. immune cells — to undertake comparable work later this 12 months.
The immune system additionally goes by means of age-related adjustments — for instance, T-cells change into much less energetic in area resulting in an elevated susceptibility to an infection.
The truth is, most bodily processes are affected — even eyesight, as the shortage of gravity means fluid and blood pool close to the optic nerve, affecting the sharpness of imaginative and prescient. In the meantime, the muscle mass that management blood vessels change into much less efficient as they not work towards gravity — and the guts doesn’t need to pump as laborious, so inside days begins to vary from an oval to a ball form (most adjustments seem to reverse, with time, on return to Earth).
However it’s muscle mass and bones that maybe take the most important hit — after astronaut Frank Rubio spent 371 days in area, he needed to be lifted from the spacecraft to forestall him falling as he was so weakened by the mission.
That’s largely because of the lack of gravity — which mimics the affect sedentary life and ageing has on us right here.
With out realising it, we push towards gravity with each motion; this builds our muscle mass whereas making certain previous cells get damaged down and stimulating the manufacturing of recent ones.
In area, many muscle mass are barely used and the bones begin to leach previous bone, calcium and different vitamins, but the method to supply new bone cells doesn’t kick in, explains Professor Caplan.
(A research printed in PLoS One in 2020 estimated {that a} third of astronauts would develop osteoporosis throughout a three-year spherical journey to Mars — placing them vulnerable to fractures with minimal affect.)
‘On Earth, sedentary life imply we underuse muscle mass and underload bones,’ says Professor Caplan.
A lot of the work at Northumbria is aimed toward lowering this muscle loss and the ensuing well being complaints equivalent to decrease again ache — a typical downside for area travellers, and some of the widespread causes for a go to to the GP within the UK.
The truth is, among the tools being researched at Northumbria might profit mere mortals greater than it does astronauts.
Take ‘FRED’ (which stands for practical readaptive train system), which appears like a cross coach however is specifically tailored to work simply the muscle mass across the backbone and deep within the stomach. These muscle mass assist the backbone — in the event that they change into weakened, it might result in stiffness and ache.

FRED, which has been beneath growth since 2009, has been designed to assist astronauts rehabilitate after area flight.
Nonetheless, the crew is hoping to develop a model that might be utilized in clinics or GP surgical procedures.
‘When somebody has decrease again ache, the muscle mass across the decrease backbone change into smaller — whether or not that arises from the ache lowering mobility so the muscle mass are used much less, or as a result of the messages travelling from the mind to the muscle mass turning into dysfunctional varies from individual to individual,’ says Kirsty Lindsay, an assistant professor of rehabilitation sciences who’s a part of the Northumbria crew.
The idea is that strengthening these muscle mass helps the backbone higher and improves mobility and ache. ‘However it’s laborious to work these muscle mass consciously,’ says Dr Lindsay.
Enter FRED: To make use of it, you have to stand upright with out holding the hand helps and slowly pedal — in contrast to a standard cross-trainer, there is no such thing as a resistance from the foot plates, so you have to use your interior core muscle mass to regulate the motion and keep balanced in any other case your ft spin spherical. (As I found, it’s each bit as tough because it sounds). Whereas the proof thus far suggests it has potential for astronauts, a research printed within the journal Musculoskeletal Science and Apply in 2020, involving 13 non-astronauts with continual decrease again ache, had extra spectacular findings.
Contributors used FRED for as much as quarter-hour, 3 times every week, for six weeks.
‘What we discovered, anecdotally, is that in some individuals, the period of time they had been in ache diminished — however essentially the most placing discovering was that they’d dramatically higher exercise ranges in comparison with earlier than,’ says Professor Caplan.
‘They had been in a position to resume hobbies equivalent to golf and gardening, which was out of the query earlier than. That enchancment was maintained once we noticed them once more after six weeks.
‘There aren’t another train units that prepare these muscle mass in the appropriate method to assist with spinal postural management,’ he provides.
This machine that was supposed to assist get astronauts on their ft can also be being examined as a remedy for girls with urinary incontinence post-childbirth.
‘We’re simply ending a research to see whether or not FRED may help the pelvic ground muscle mass — this might be revolutionary as there hasn’t been a lot growth on this space since 1948,’ says Dr Lindsay.
The research individuals accomplished 12 train periods, every as much as half-hour, over 4 to 6 weeks.
‘To date the outcomes appear encouraging,’ says Dr Lindsay — the total outcomes will probably be printed within the subsequent 12 months or two.
As area missions are a few years within the planning, among the units being examined at Northumbria could also be used on Earth beforehand.
As an illustration, a model of a tourniquet that’s wrapped round a limb to enhance the impact of train — hopefully due in area within the subsequent couple of years — is being utilized by an NHS hospital on sufferers after knee surgical procedure. It’s primarily based on the precept of blood move restriction train, which makes any train you do more practical.
Luke Hughes, an assistant professor of area physiology at Northumbria, explains: ‘Low-intensity train is in itself not efficient at constructing muscle and bone — for that, you want higher-intensity resistance [e.g. with weights] or cardio train [which raises the heart rate].’
However with out gravity to work towards, it’s more durable to do high-intensity train in area; equally, low-intensity train could also be all ‘somebody who’s had surgical procedure, or who has weakened bone by means of osteoporosis, for instance, can do’, says Dr Hughes.
The tourniquet is inflated round a limb — like a blood stress cuff — to a stress individualised to the wearer. This restricts blood move — and subsequently oxygen move — to the muscle mass, and prevents by-products of train, metabolites, being eliminated, ‘recreating the situations that you’d get within the muscle mass and different tissues throughout high-intensity train’, says Dr Hughes.
This strengthens muscle and bone with minimal motion. Dr Hughes labored with a producer in Canada to change a mannequin they’d already designed.
In a research, printed within the journal Sports activities Drugs in 2019, he discovered that in sufferers who’d had surgical procedure to restore the anterior cruciate ligament (ACL) within the knee, those that used the tourniquet twice weekly whereas doing low-impact leg workout routines had ‘considerably’ much less ache and higher motion and larger muscle growth, in contrast with those that had been utilizing heavy weights to do leg presses.
In consequence, College Faculty London Hospital, the place the research was carried out, now makes use of the system for rehabilitation after knee surgical procedure (significantly for ACL) with low-intensity train (this additionally reduces the possibilities of the affected person injuring themselves once more).
Maybe not surprisingly, Premier League soccer golf equipment have been in contact with Dr Hughes.
Competitors to get scientific tools on to tightly packed spacecraft to be examined is so fierce that a lot of the crew’s analysis is finished on Earth in situations that mimic low gravity, equivalent to in ‘mattress relaxation’ research.
These research are rather more arduous than they sound, as volunteers should lie on their backs on a tilted mattress, their head under the extent of their ft, 24 hours a day for 60 days.
This recreates the consequences of being in a microgravity surroundings, the place blood and different fluid pulls in the direction of the stomach and head.
‘You don’t get that compression of the backbone and the joints which usually occurs on Earth both,’ says Professor Caplan.
It sounds tortuous — ‘it might ship me mad,’ admits Professor Caplan.
Recruits are paid round £14,000 — ‘apparently they get legal professionals who say they’re going to work on caseloads — and college students revising for exams,’ says Dr Hughes.
Later this 12 months the Northumbria crew will run a mattress relaxation research led by the European House Company in Slovenia, to see if there’s a technique to spot whether or not the best way somebody strikes can predict the chance of growing weakened muscle mass round their backbone — and again ache.
Contributors will put on reflective markers so their actions will be tracked in 3D by digicam sensors earlier than and after the enforced ‘relaxation’.
‘Doubtlessly, we might then develop an app linked to wearable tech that may detect once you aren’t transferring throughout the regular vary to provide you with a warning to the chance of growing again ache or postural instability,’ Professor Caplan says.
There are lots of hurdles but to beat — not least as a result of the adjustments in our our bodies in area aren’t simple.
Whereas many elements of our physique age sooner, the telomeres — the constructions that sit on the tip of every strand of our DNA, a bit just like the tip of a shoelace — that assist shield our genes from injury, unexpectedly get longer throughout the flight: usually these shorten with age.
Scientists are investigating what it could imply for longer-term area journey — and for the remainder of us.
Even so, Dr Alsaleh says: ‘We’re getting into an extremely thrilling period, the place we will use our information gained from area to extend the quantity of life that we spend in good well being.’
And who wouldn’t welcome that?
