Photo credit: NASA/Bill Ingalls During space travel, astronauts are exposed to a lack of gravity. This affects their physiology in different ways, including cardiovascular and musculoskeletal deconditioning, eye changes and immune dysfunction. Studies … Continue reading How Our Bones Adapt in Space
If you’ve ever seen a house being built, you’ll recognize the wooden framework as the beginning of the structure. Just as this framework provides the structure for the insulation, walls and roof of a house, our bones are also a strong framework. Bones provide a firm support system that protects our internal organs and give … Continue reading Spotlight On: The Skeletal System
Your gut contains tens of trillions of microorganisms, including at least 1,000 different species of known bacteria. Even though these bacteria are microscopic in size, they are so abundant that they make up 1 to 3 percent of your total body mass! Many of these microorganisms that live in the body are actually beneficial to … Continue reading How Are Gut Bacteria and Bone Related?
Physiology, the study of function from microscopic cells to complete organ systems, encompasses a wide range of fascinating topics. The annual Experimental Biology (EB) meeting is a showcase for thousands of researchers studying humans and animals alike. Check out some of the research presented at last month’s meeting in Chicago: Most people know that walking … Continue reading Walking and the Brain, Aromatherapy for Horses and a Whole Lot More!
Turning on the television, I inhale deeply as the Olympic marathoners stride across cities to compete for their shot at a medal. As an exercise physiologist, I find all athletes particularly amazing. These men and women devote themselves to their training, pushing for just one more mile with each run. That extra mile provides a … Continue reading Go for a Longer Run…Your Bones Will Thank You
Astronaut Scott Kelly came back from 340 days in space two inches taller. Along with height, many aspects of the body change because of the weightlessness environment of space. The body loses muscle, heart and bone mass because it no longer has to support itself as it does on Earth. There is also no feeling … Continue reading You Don’t Have to Leave the Stratosphere to Feel Like You’ve Been in Space
As a species, our bones have gone through many changes over time. A recent report published in the Proceedings of the National Academy of Sciences suggests that as humans transitioned from hunter-gatherer culture to farming our food, our bones became weaker. Today in the U.S., approximately 50% of women and 25% of men over 50 … Continue reading Keep Bones Strong by Making Workouts a Priority
