How female runners can improve speed and safety | 90 Seconds w/ Lisa Kim – Stanford Medicine

The idea that a leaner body makes for a faster stride is common among distance runners. But it’s inaccurate and sets a dangerous ideal. Runners who are excessively lean are prone to injuries, infectious diseases, mental health problems and loss in bone density, said Michael Fredericson, MD, a professor of orthopaedic surgery who has served for decades as the Stanford University track team head physician. Female runners are more likely to suffer these effects, he noted.

During his career as the head team physician, Fredericson has seen so many athletes with problems related to low body weight — including bone stress injuries, menstrual irregularity and osteoporosis, or loss of bone density — he decided to study ways to prevent it.

How long does it take to run a marathon? – TODAY

Michael Fredericson, a practicing physician and director of the Physical Medicine and Rehabilitation division of Stanford University, tells that long-distance running is unique from other forms of cardio as it strengthens muscle fibers, “which makes your muscles increasingly fatigue-resistant,” he says. He adds that research also shows that first-time marathoners “experience beneficial reductions in blood pressure and aortic stiffness equivalent to approximately a four-year decrease in vascular age.”

Body Hacking: Using Exercise Physiology to Slow Aging with Anne Friedlander – Stanford Alumni

Physical activity is a powerful medicine that can promote health and change the trajectory of aging. However, in the modern world, we have drifted away from incorporating physical activity into our lives. As the barriers to daily movement have gotten stronger, the burden to exercise has gotten greater. As scientists learn more about the pathways of disease, the causes of aging and the mechanisms by which exercise exerts its benefits, we can develop targeted exercise strategies that can slow (i.e. “hack”) the aging process. In this session, we will discuss how physical activity can slow aging and how different types and amounts of activity can optimize desired health and fitness outcomes.

Should I exercise outside when the air is smoky from wildfire? – San Francisco Chronicle

“Once it gets to red, purple or maroon …it’s really not safe,” said Dr. Michael Fredericson, a Stanford sports medicine doctor. “The potential negative outweighs the positive at that point.”

Morning Workouts are Linked to Better Weight Management, Study Finds – Healthline

Dr. Michael Fredericson, director of the PM&R Sports Medicine and co-director of the Stanford Center on Longevity at the Stanford University School of Medicine, said the way the study was conducted it was unclear if the people who exercised in the morning were “systematically different from those who exercise at other times in ways not measured in this study.”

“For example, people who exercise regularly in the morning could have more predictable schedules, such as being less likely to be shift workers or less likely to have caregiving responsibilities that impede morning exercise,” Fredericson said.

Walking Just 4,000 Steps a Day Can Help You Live Longer – Healthline

“What is different is that previous studies have suggested you need at least 4,000 steps per day and ideally 6,000 to 8,000 for significant benefit.” Dr. Michael Fredericson, a professor of orthopedic surgery at Stanford Health Care who was not involved in the study, told Healthline.

“However, this study suggests we do not need as many steps to have health benefits, and they can manifest starting with even 2,500 to 4,000 steps a day,” Fredericson added.

Stacy Sims, MSC, PHD, is a forward-thinking international exercise physiologist and nutrition scientist who aims to revolutionize exercise nutrition and performance for women. She spoke with Katie Couric about why exercise is so important for women as we get older, and the best exercises for women in different stages of menopause.


Speeding Up Your Daily Walk Could Have Big Benefits – The New York Times

“Activity tracker data is going to be better than self-reported data,” said Dr. Michael Fredericson, a sports physician at Stanford University, who was not involved in the study. “We know that people’s ability to self-report is flawed,” often because people don’t accurately remember how much exercise they did in a day or week.

How To Tell The Difference Between Soreness And Injury After A Workout – HuffPost

” One red flag is swelling around a joint after a workout, according to Dr. Michael Fredericson, a sports medicine physician at Stanford Health Care.”

Any stiffness around joints in the knees, hips, ankles or lower back is also concerning, he said, while adding that stiffness around a muscle you worked out is normal.

You should take notice if joint or muscle stiffness is ever “impairing your ability to walk,” Fredericson said. If that’s the case, you should get in touch with your doctor.
