LECTURE 12 – Traning the female, elite, children and masters
Factors important to women involved in vigorous training
- Similar to males
oThermoregulations impaired during luteal phase of menstrual cycle: higher core
temp threshold is required to initiate sweating
- Concern for female athletes
oExercise and menstrual cycle
oEating disorders
oBone mineral density
oExercise during pregnancy
- Exercise ad menstrual disorders
oAmenorrhea (generally < 4 menses per year)
Cessation of menstruation
Called athletic amenorrhea
Due to multiple factors
Amount of training
Psychological stress
Body composition
oTraining and menstruation

oOsteoporosis
Loss of bone mineral content
Gymnastics; training indoors – lack vit D from sun, less calcium
consumption, high impact training – hurts bones
oMajor causes
Estrogen deficiency due to amenorrhea
Inadequate calcium intake due to eating disorders
- Female athlete triad
oInterrelated health problems
Amenorrhea
Eating dosorders/disordered eating
Bone mineral loss
oPrevalence
4% of all female athletes meet critera for triad
26% possess at leat two components
oEating disorder can lead to
Diminished intake of calcium and vitamin d
Amenorrhea and low blood levels of estrogen
Can lead to low bone mineral density
