I am in my tenth week of an intens(iv)e training program to run a half marathon in November. Perhaps running the race is wishful thinking, but the training is keeping me focused during the pandemic. The training is based on Stacy Sims’ book, Roar: How to Match Your Food and Fitness to your Female Physiology for Optimum Performance, Great Health, and a Strong, Lean Body for Life.
Sims’ claim based on her own research as an exercise physiologist and nutrition scientist is that people who have more estrogen and progesterone and other hormones we have traditionally called “female” cannot be trained as small men as they have been for decades. During the high hormone phase of the menstrual cycle for those who menstruate, the body has a harder time taking up protein. If you don’t get significant protein within 30 minutes of a workout, the body recovers by taking protein out of muscles — basically eating the muscles instead of building them. In addition to the different needs brought about by different hormones, the different physiology, specifically for example broad pelvic bones, lead to less stability in the knees and thus more of a likelihood to be knock-kneed — and in running to have less stability and a tendency for knees to collapse in — unless glutes are significantly strengthened. Even really strong women athletes can have strong quadriceps and still buckle their knees when they jump if they aren’t working on building all three gluteus muscles.Read more
