ESS 345 FINAL EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
Which of these statements bests describes the effects of amphetamines on the
body?
Ergogenic but dangerous
B- Blockers can lead to
Low BP
Due to caffine's effect on fluid balance in the body, it could also be used as a
diuretic
The combination of alcohol plus energy drinks yields a
Ergolytic response
At higher doses, steroid use leads to
greater effects
Steroid use has little or no effect on
aerobic capacity
In men, steroid use can lead to
higher estrogen secretion
according to research findings, hGH would be most helpful as an ergogenic aid
for
older men
,bicarbonate loading is considered an ergogenic because aid because of its
supposed effects on
buffering capacity
Creatine supplementation would be most helpful for a
track runner
other than physically supporting our bodies, bones serves an important function
as a
calcium reservoir
bone mineral density peaks around the age of
25- 35
from childhood to adulthood, increases in muscle mass (even in the absence of a
training program) are primarily due to
fiber hypertrophy
fat deposits increase through childhood and adolescence due to
increase in size of fat cells
high levels of muscle strength, power and skill are not possible in children until
nerve myelination occur
which of these cardiovascular variables is higher during a single bout of
submaximal exercise in children and adults
Heart rate
why does stroke volume increase from childhood through adolescence to
adulthood?
heart increases sizes
, Resistance training leads to strength gains in children through which mechanism
Neural mechanisms
Anabolic steroid use leads to a significant increase in _____ capacity and
performance
anaerobic
why does maximal HR decrease with age
adrenergic receptor desensitization
in older populations, a beneficial change in body composition will most likely
result from
resistance training
exercise training in older populations affects the neural reflex function by
attenuating loss of reflex speed
which of these cardiovascular changes in the primary cause of age related
decrements in VO2max?
Lower maximal rate
Maximal stroke volume is reduced in older hearts because
blunted frank starling mechanism, depressed response to catecholamines, ventricular
stiffening
how do skeletal muscle arterioles in older individuals compensate for reduced
blood flow during exercise
enhanced muscle oxygen extraction
Skeletal muscle vasodilation improved after habitual exercise in older individuals
due to
