  • NASA Investigates How Dormant Viruses Behave during Spaceflight | 03.21.19 – In preparation for continued human spaceflight missions farther into space to the Moon and Mars, NASA continues to investigate how the human immune system reacts in spaceflight. Certain viruses, such as the Varicella Zoster Virus (VZV) that causes chickenpox in childhood or shingles in adults, are not fully eliminated from one’s body. The immune system controls them and maintains the virus in a “dormant” state in the spinal cord nerve cells of the body.

  • NASA’s One-Year Mission Investigates How Space Affects Astronauts’ Functional Performance | 09.13.17 – Adapting to the microgravity environment of space changes the way your brain interprets sensory signals, decreases muscle strength and alters cardiovascular function. Astronauts will need to overcome these changes to perform critical mission tasks on a journey to Mars.
  • Exercise Countermeasures Lab at NASA Glenn | 06.15.17 – The Exercise Countermeasures Laboratory at NASA Glenn Research Center provides high-fidelity weightlessness for exercise simulations for developing exercise countermeasure devices, equipment and exercise protocols for spaceflight.
     
  • Peek into Your Genes: NASA One-Year Mission Investigators Identify Links Between Genes, Vitamins, Fluids and Vision Problems | 05.30.17 – Coinciding with May – Healthy Vision Month, NASA’s One-Year Mission investigators are peering into their new findings to help address astronaut vision issues. While the One-Year Mission has concluded for retired astronaut Scott Kelly, NASA’s Human Research Program is focusing on comparing previous six-month mission findings to One-Year Mission preliminary findings.
  • Space Station Live: The ISS Workout Plan  | 02.04.16 – NASA Commentator Lori Meggs talks with Gail Perusek of NASA’s Exercise Countermeasures Lab at the Glenn Research Center about the exercises that keep International Space Station crew members healthy during extended missions in weightlessness and how the scientists design the hardware for use on orbit. Resistance and aerobic exercises are vital to keeping the crew members healthy in an environment where they don’t even have to work against the pull of gravity in their day to day lives.
  • NASA Now: Exercise Physiology: Countermeasures   | 05.14.13 – Aaron Weaver is a biomedical engineer responsible for setting up and running experiments and recruiting test subjects in the Exercise Countermeasures Laboratory at NASA’s Glenn Research Center in Cleveland, Ohio. He develops biomedical technology and mathematical modeling of possible injury scenarios involving astronauts in space. Weaver discusses the importance of exercise in space and the research being conducted at NASA. This research will enable humans to safely travel farther into outer space as we increase our understanding of the human body.
     
  • (REMOVE – 404) The Human Factor – Meet the People Behind the HRP | 04.25.13 – The Human Factor – Meet the People Behind the HRP. Lori Ploutz-Snyder, Lead Scientist for Exercise Physiology and Countermeasures at NASA JSC reflects on the deconditioning that’s associated with weightlessness and the design of exercise programs to maintain cardiovascular fitness; skeletal health and muscle strength; endurance; and performance, both during and after spaceflight.
