“The phase of the menstrual cycle significantly affects a female runner’s hormonal environment and therefore her physiology,” Karp explains. In the forthcoming book Running for Women (Human Kinetics, 2012), Karp and coauthor Carolyn Smith, MD, explain how various aspects of physiology are affected by the phase of the menstrual cycle, including oxygen consumption, body temperature, and metabolism. Metabolism“Menstrual-phase variations in running performance may largely be a consequence of ...
In this insightful webinar, Dr. Jason Karp delved into the science of a woman, discussing her unique physiology and offering recommendations for training to maximize results. He is in demand as a presenter at numerous coaching, fitness, and academic conferences, including U.S. Track & Field and Cross Country Coaches Association, American College of Sports Medicine, American Society of Exercise Physiologists, and IDEA World Fitness Convention. The founder and coach of REVO2LT running team ...
In the book Running for Women (Human Kinetics, 2012), Karp and coauthor Carolyn Smith, MD, explain how various aspects of physiology are affected by the phase of the menstrual cycle, including oxygen consumption, body temperature, and metabolism. “Breathing is greater during the luteal phase, when progesterone concentration is highest, making women feel more winded during luteal-phase workouts compared to follicular-phase workouts. Body Temperature Body temperature changes rhythmically ...
Champaign, IL—Female runners often correlate weight loss with body fat reduction when attempting to manipulate body composition and enhance performance. “Weight loss in relatively lean female runners is detrimental to their health and can result in a loss of lean body tissue and lead to worsened performance,” Karp says. “Despite negative consequences, the desire to attain the ideal body composition to improve performance is the primary impetus contributing to the development of the female ...
At slower speeds, your muscles rely more on fat and less on carbohydrate, and as you increase your running pace, the energy contribution from fat decreases while the energy contribution from carbohydrate increases. When women increase their total caloric intake as they also increase the amount of carbohydrate in their diets, they increase their muscle glycogen content by a similar amount as men. Because endurance-trained females use less muscle glycogen and rely more on fat than endurance-...
Initial guidelines placed restrictions on exercise intensity and duration, limiting women to a heart rate of less than 140 beats per minute and restricting exercise to 15 minutes or less. To learn more about exercising during pregnancy, read Running for Women. Although restrictions on heart rate and exercise duration were removed, these guidelines offered only cautious approval to women wanting to engage in exercise while pregnant.
Although stress fractures and patellofemoral pain syndrome are the most common running-related injuries among women, other overuse injuries can occur in female runners, including iliotibial band syndrome, plantar fasciitis, and Achilles tendonitis. To learn more about common injuries for women runners, read Running for Women. Iliotibial band syndrome (ITBS) is the most common cause of pain on the outside of the knee among runners and occurs from repetitive friction of the iliotibial band ...
Champaign, IL—Busy moms know that finding time for a run can often be a challenge. In his book, Running for Women (Human Kinetics, 2012), Karp offers seven strategies for balancing motherhood and running. If you can’t run first thing in the morning, try running after your kids have gone to bed.
