ROARing into the New Year

by Dr Stacy Sims
Oct 14, 2024

The new revised edition of ROAR is out! Here’s what’s new.

When I started working on ROAR nearly ten years ago, it was still considered fringe to say that women’s unique hormones and their menstrual cycles could impact everything from performance to injury risk to hydration and beyond. That was despite elite, high-achieving athletes like elite runner Paula Radcliffe and tennis champion Heather Watson lamenting openly in the press during that time, menstruation was still woefully under-discussed and misunderstood among athletes and their trainers. 

Fast forward a decade, and you have research showing, as we discussed in ROAR, that every single cell is impacted by our hormonal milieu. In fact, neuroscientists are even studying for the first time how the ebb and flow of the hormones that orchestrate the menstrual cycle appear to reshape the brain, which makes sense in light of research showing that the structure, connectivity, and energy metabolism of the brain also changes during perimenopause. We’ve also seen research suggesting that combined oral contraceptives could impair emotional regulation in women. And, of course, there’s ongoing research on how this impacts exercise and sports performance, which is a topic of ongoing study.

(And for transparency here, I was one of the first to start talking about this, about 7-8 years ago). That advice was groundbreaking at first. It...
What Racing Kona Taught Me
  Racing Kona Taught Me More Than I Ever Expected In October 2000, I stood on the start line of the Ironman World Championship in Kailua-Kona, Hawaii. I had no idea that day would shape the rest of my career—not just as an athlete, but as a scientist. Kona is brutal. It’s long, hot, humid, windy, and relentless. But it’s also iconic—and for many, the pinnacle of endurance sport with its 2.4-m...
Train for Power—Not Just Strength
  Most active women love to move. Whether it’s running, riding, swimming, lifting, yoga, or simply chasing your kids around, we love to break a sweat and feel the physical and mental benefits that come from that. But there’s one form of training that too often gets overlooked: power training. Whether it’s due to outdated myths (“I don’t want to bulk up”), lack of time, or just not knowing whe...
