I remember 20 years ago when I was in the working world, I definitely lived a sedentary lifestyle. Long hours at the office, a child at home and all the aspects of family life made it difficult for me to exercise a lot. Vedging out in the evening in front of the TV proved a welcome relief from daily demands. In addition, my motivation was elsewhere. Now that I am retired that has all changed, but I understand if you may be where I was back then.
Here I am riding with Gabi. Cycling is a super form of exercise for both mind and body.
Blame it on a job change, a chronic health issue, or simply a loss of motivation: whatever took you away from your regular exercise routine has led to a sedentary lifestyle. But don’t assume you can jump back into the same exercise regimen you followed when you were younger. “Your body has aged, and things have changed,” says Dr. Clare Safran-Norton, clinical supervisor of rehabilitation services at Harvard-affiliated Brigham and Women’s Hospital.
Age-related physical changes aren’t always obvious. “We lose muscle mass and strength as we get older, and the muscles become less flexible and less hydrated,” says Dr. Safran-Norton. Arthritis weakens joints. And vision changes, neurological disease, joint pain, or problems inside the ear can throw off your balance. Continue reading
At the risk of sounding sexist, I am surprised by these findings. I guess because men are generally bigger and stronger, I assumed the opposite was true.
Women can process oxygen more quickly than men when they start to exercise, according to a new study from the University of Waterloo.
Stanford professor Michel Serres hikes the Dish on a regular basis.
Quick oxygen uptake places less strain on the body’s cells and is considered an important measure of aerobic fitness.
“The findings are contrary to the popular assumption that men’s bodies are more naturally athletic,” said Thomas Beltrame, lead author on the study.
The study compared oxygen uptake and muscle oxygen extraction between 18 young men and women of similar age and weight during treadmill exercise. Women consistently outperformed men with around 30 per cent faster oxygen handling throughout the body.
“We found that women’s muscles extract oxygen from the blood faster, which, scientifically speaking, indicates a superior aerobic system,” said Richard Hughson, a professor in the Faculty of Applied Health Sciences, and Schlegel Research Chair in Vascular Aging and Brain Health at Waterloo.
By processing oxygen faster, women are less likely to accumulate molecules linked with muscle fatigue, effort perception and poor athletic performance.
“While we don’t know why women have faster oxygen uptake, this study shakes up conventional wisdom,” said Beltrame. “It could change the way we approach assessment and athletic training down the road.”
The study is published in Applied Physiology, Nutrition, and Metabolism
