HONOURS :
''' TOM CRUISE TOP '''
THE WORLD STUDENTS SOCIETY - the exclusive and eternal ownership of every student in the world - rises, to give actor Tom Cruise a standing ovation, and bestow on him the Lifelong Membership of !WOW!.
THE SUPER STAR famously does all of his own stunts in the Mission: Impossible films. A physiology academic considers what kind of training and skill goes into some of the most spectacular ones....................
HE'S LEAPT FROM CLIFFS - CLUNG TO PLANES mid-takeoff and held his breath underwater for as long as professional freedivers. Now, at 62, Tom Cruise returns to Ethan Hunt for one final mission - and he's still doing his own stunts.
With Mission: Impossible - The Final Reckoning, the saga reaches its high-stakes finale. But behind the scenes of death-defying spectacles lies a fascinating question : just how far can the human body be pushed - and trained - to pull off the seemingly impossible?
And at what cost? In filming the eight Mission: Impossible films, Cruise has suffered a broken ankle, cracked ribs and a torn shoulder.
Your mission, should you choose to accept it, is to consider the capabilities - and limits - of the human body in being able to achieve these awesome heights. How much is it possible to train to achieve the apparently impossible?
BREATHING UNDERWATER : In Mission: Impossible - Rogue Nation, Hunt navigates an underwater vault to recover a stolen ledger. Cruise wanted to film this all in one take and sought help from freediving instructors in order to hold his breath for the required time - over six minutes!
The average human can hold their breath for about 30 to 90 seconds. That's without training. Although there's an innate diving reflex built into the human body that allows it temporarily adapt to immersion underwater.
The response is to lower the heart rate and redirect blood to the body's core, essentially enabling it to lower its metabolic demand and preserve the function of the vital organs, like the brain and heart.
All well and good, but consider now the need to swim, as well as resist the pressure of the water pressing on the lungs. And also while fighting the desperate urge as a result of rising CO2, to take a deep breath - which, underwater, would be catastrophic.
And if the diver's oxygen level falls too low, they might black out and lose consciousness. That's why shallow water drowning is a real risk here.
That's where freediving training comes into play. With practice, there are several ways you can increase the time you're able to remain underwater. These include mastering breathing techniques to retain the maximum amount of air in the lungs.
Sustained practice might also lead to increased oxygen storage capacity in the bloodstream.
This process takes months to years to attain and might lengthen the immersion time, on average to around five minutes. What Cruise managed to achieve was nothing short of exceptional.
FREE CLIMBING - AND THAT SCENE : Mission: Impossible films often open with Ethan Hunt working his way up some impossible sheer building or cliff face with the agility of a mountain goat.
He appears to be free climbing without a harness, and at the start of Mission: Impossible 2, clinging on with just one hand. While Cruise used safety wires to secure himself, the climbing was 100 percent real.
Then, of course, how could we forget the scene? The one in the original Mission: Impossible - where he has to suspend all limbs, centimeters from the ground, to prevent himself from setting off the alarms.
Although Cruise hasn't revealed his specific training regime for these stunts that I can see performing any of these actions would require an exceptionally strong back and core.
The muscles of our backs keep the spine straight and upright. Some span the space between back and limb, such as latissimus dorsi, or ''lats.'' These sheets of muscle, prized by bodybuilders are also particularly valuable to climbers - allowing you to perform a chin up, or pull yourself up that rock face.
Besides this, many other muscles are needed for extreme climbing - those that enable a strong grip, allow for reaching and '' push offs, '' and maintain tension and hold. It's no womder climbing is considered one of the best whole -body workouts.
It's no surprise that Cruise is known to have trained extensively for this. To understand even an element of the difficulty he may have faced, you could try adopting that vault heist poise, with your belly in contact with the floor, and see how long you can hold it. I won't tell you how pitiful my own attempt was.
The Honour and Serving of the Latest Global Operational Research on great artists, actors, brave and daredevil heroes, continues.
The World Students Society thanks Senior Lecturer, Dam Baumgardt, School of Physiology, Pharmacology and Neuroscience at the University of Bristol, UK.
With respectful dedication to Tom Cruise Fans, Grandparent, Parents, Students, Professors and Teachers of the world.
