3 phases of follicular phase: - correct answer-o 1. Early Follicular: menstruation
o 2. Mid Follicular:
Pituitary --> ↑ FSH
FSH --> Ovaries --> ↑ Estrogen
o 3. Late Follicular:
Estrogen --> ↑ LH --> Ovulation
3 phases of luteal phase - correct answer-o 1. Early Luteal:
Ovulation --> ↑ Progesterone
o 2. Mid Luteal:
↑ Progesterone • ↑ Estrogen
o 3. Late Luteal:
No pregnancy --> ↓ P, ↓ E --> menstruation
A decrease in plasma volume and an increase in the hematocrit of the blood would result in
_________________ blood flow. - correct answer-decreased
A disadvantage of body weight exercises is: - correct answer-Potential for progression and
overload
A female athlete wants to improve the muscular endurance of her upper body. Using 3 sets
of 15 reps per exercise, which of the following rest period lengths will maximize her goal? -
correct answer-30 seconds
A high H+ concentration can contribute to fatigue by: - correct answer-
A highly successful endurance athlete would likely have __________ compared to a
sedentary person. - correct answer-A higher percentage of type I fibers
A highly trained endurance athlete would be expected to have which of the following
compared to an untrained individual: - correct answer-
A major regulator of protein synthesis and muscle size is _____________. - correct
answer-mTOR
A muscular contraction that results in a change in muscle length, at a variable speed is
called an: - correct answer-isotonic contraction
A training period of increased metabolic stress that results in a short-term decrease in
performance capacity is called: - correct answer-
acclimatization to altitude effects - correct answer-improved oxygen carrying capacity,
increased red blood cell production, increased hemoglobin oxygen saturation
, Aerobic training has been shown to reduce the oxygen deficit at the start of submaximal
exercise. This is most likely due to which factor? - correct answer-Increases in the number of
mitochondria and capillaries.
Aerobic training is associated with alteration in the: - correct answer-
Aerobic training results in a lower resting heart rate primarily because of: - correct
answer-Greater parasympathetic tone
All of the following are reasons EPOC is generally higher following heavy exercise compared
to light exercise except for: - correct answer-Heavy exercise is of shorter duration than light
exercise
All of the muscle fibers in a motor unit are the same fiber type. - correct answer-true
An accumulation of which substance would inhibit enzyme activity in regulating energy
metabolism? - correct answer-
An athlete with a high lactate threshold would be expected to have: - correct answer-High
contribution of anaerobic metabolism for energy production
An RER of 0.95 during steady-state exercise is suggestive of - correct answer-
An untrained individual would be expected to have which of the following compared to a
trained individual - correct answer-greater reliance on carbohydrate at a given intensity
As exercise intensity increases, there is a progressive increase in the reliance of
carbohydrate metabolism in the exercising skeletal muscles. The point at which the percent
contribution of carbohydrate is greater than the percent contribution of fat is described as
the: - correct answer-crossover effect
As exercise intensity increases, ventilation increases as a result of: - correct answer-
At higher intensities (>60% VO2max), the major determinant of cardiac output for most
individuals is: - correct answer-heart rate
autocrine hormone transport - correct answer-acts on receptors of originating cells
benefits of exercise during pregnancy: - correct answer-↓ excessive weight gain
↓ risk for gestational diabetes
↑ fetal development
↓ risk of premature labor
↓ labor duration
↓ incidence and severity of postpartum depression
↑ postpartum recovery
