Crimson wine may also help astronauts keep sturdy on Mars journey. Right here’s why

Red wine can help astronauts stay strong on Mars trip. Here’s why


Astronauts who want to undertake the nine-month journey from Earth to the Mars sooner or later could be higher off sipping purple wine throughout the journey, suggests new analysis from Harvard College.

Out in house, unchallenged by gravity, muscular tissues and bones weaken. Weight-bearing muscular tissues are hit first and worst, just like the soleus muscle within the calf.

So the researchers wished to learn the way to ensure the astronauts can keep sturdy after the journey.

Printed in Frontiers in Physiology, the research confirmed that the purple wine part resveratrol considerably preserves muscle mass and power in rats uncovered to the losing results of simulated Mars gravity.

“After simply three weeks in house, the human soleus muscle shrinks by a 3rd,” mentioned Marie Mortreux, lead writer of the NASA-funded research.

“That is accompanied by a lack of slow-twitch muscle fibers, that are wanted for endurance,” Mortreux mentioned.

To permit astronauts to function safely on lengthy missions to Mars — whose gravitational pull is simply 40 per cent of Earth’s — mitigating methods will likely be wanted to forestall muscle deconditioning.

“Dietary methods may very well be key, particularly since astronauts travelling to Mars received’t have entry to the kind of train machines deployed on the ISS,” mentioned Mortreux.

A powerful candidate is resveratrol: a compound generally present in grape pores and skin and blueberries that has been extensively investigated for its anti-inflammatory, anti-oxidative, and anti-diabetic results.

“Resveratrol has been proven to protect bone and muscle mass in rats throughout full unloading, analogous to microgravity throughout spaceflight. So, we hypothesized {that a} average each day dose would assist mitigate muscle deconditioning in a Mars gravity analogue, too,” Mortreux mentioned.

To imitate Mars gravity, the researchers used an strategy during which rats have been fitted with a full-body harness and suspended by a series from their cage ceiling.

Thus, 24 male rats have been uncovered to regular loading (Earth) or 40 per cent loading (Mars) for 14 days. In every group, half acquired resveratrol (150 mg/kg/day) in water; the others received simply the water. In any other case, they fed freely from the identical chow.

Calf circumference and entrance and rear paw grip pressure have been measured weekly, and at 14 days the calf muscular tissues have been analysed.

As anticipated, the ‘Mars’ situation weakened the rats’ grip and shrank their calf circumference, muscle weight and slow-twitch fiber content material.

However extremely, resveratrol supplementation nearly solely rescued entrance and rear paw grip within the Mars rats, to the extent of the non-supplemented Earth rats.

What’s extra, resveratrol utterly protected muscle mass (soleus and gastrocnemius) within the Mars rats, and particularly lowered the lack of slow-twitch muscle fibers.

“Additional research are wanted to discover the mechanisms concerned, in addition to the results of various doses of resveratrol (as much as 700 mg/kg/day) in each women and men,” Mortreux mentioned.
