Purpose • Examine gender differences and issues concerning women and resistance training. • Educate female athletes about balance of training components
Misconceptions • Certain misconceptions about women and resistance training have limited the benefits for women due to the creation of inadequate training programs.
Common Myths • Women can’t get strong • Strength training causes women to become larger and heavier. • Women should use different training methods than men. • Women should avoid high intensity or high load training. • With the right exercise, you can get rid of trouble spots • If you don’t lose weight, there’s no point in exercising
Gender Differences • Does resistance training produce the same effects in women as it does men????? • Body Composition • Muscle Hypertrophy • Hormonal Response • Strength and Power
Body Composition • Both genders increased FFM and lowered body fat % at the same rate in a short term resistance training program (8-20 weeks). • Males generally have higher FFM than females
Muscle Hypertrophy • DEFINITION: An increase in muscle mass and cross sectional area. • Average male has greater muscle cross sectional area and more muscle fibers. • The average women’s muscles do not hypertrophy excessively. • Encouraging and discouraging for women • After a 10, 12, and 20 week study results showed no change or small changes in body circumferences in women.
Muscle Hypertrophy • Because muscle tissue is denser than adipose tissue, an increase in muscle mass accompanied by an decrease in adipose tissue equaling the gain in muscle mass will result in a slight decrease in body circumference.
Hormonal Response • Testosterone • At rest men have 10 to 20 times more serum testosterone than women. • This is why there are gender differences observed in BW and composition. It increases PRO synthesis, which induces hypertrophy.
Serum Testosterone Concentrations (pre, mid, post) Workout nmol/L
Strength and Power • Avg. woman’s maximal mean total body strength is 60% of the avg. man’s • Avg. Upper body strength is 25-55% of man’s • Lower body strength is 70-75% of man’s • Muscle’s rate of force development is slower for the avg. woman than for the avg. man. • Thus training for explosive strength is vital in order to enhance RFD and improve power performances.
More gender differences • Males muscle fibers from greatest area to smallest are Type IIA-I-IIB • Women are I-IIA-IIB • Explains strength and power output differences • Women plateau earlier in training but see greater initial strength gains.
What does this tell us? • Women are at a disadvantage physiologically than men when it comes to strength and power. • In order to reap the benefits of RT a woman has to activate her muscle tissue by lifting heavy weights (<60% 1RM).
Benefits of RT • Decrease body fat percentage • Increase in strength • Increase in muscular tone, shape, and definition • Better muscular control • Improved bone mass • Increased resting metabolic rate • Improved self esteem and confidence
Outside the Norm Larger than average increases in FFM and limb circumferences in some women are probably related to several factors… • Greater than normal resting testosterone, GH, or other hormone concentrations • Greater hormonal response than normal to RT • Lower than normal estrogen testosterone ratio • Genetic disposition to develop large muscle mass
Other Factors • Nutrition • Cardiovascular Exercise • Sport Specific Needs
Top 10 Reasons to Strength Train • Muscle is more compact than fat, so you’ll get leaner • Strength training fortifies your bones and improves flexibility, reducing the risk of osteoporosis and injury • You can reap benefits just from doing a 25 minute workout 2X a week • Research shows that the stronger you get, the more energetic and active you become. This change helps with weight control too. • Strength training raises your metabolism by as much as 15 percent, so you can eat more.
Top 10 Reasons to Strength Train • Studies indicate that it reverses age related muscle loss, dec. risk of heart disease and may cut the risk of breast, and colon cancer. • It reduces stress and anxiety • You fall asleep more quickly, sleep longer and more deeply • It improves balance, so you’ll play better • You feel stronger, which boosts confidence.
