DBP increases significantly during moderate intensity dynamic exercise
false
resting levels of vo2 are lower for trained than untrained individuals
false
a higher HR response per work-rate stage during a sub maximal exercise test resulsts in a higher estimated vo2max value
true
SBP is the predominant pressure force determining the rate of blood flow throughout the vascular system
false
stroke volume increases in a progressive and linear manner throughout all intensity stages of a grade maximal exercise test
false
when the ventilatory threshold occurs early during a road race a runner will be able to pick up the running pace and maintain it for the rest of the race distance without slowing down
false
assuming that individuals are not trained cyclist, vo2max values from treadmill ergometry test are typically higher to those of cycle ergometry tests
true
Maximal HR
tend to be similar between men and women
resting, submaximal, and maximal stroke volume
man's is higher
Maximal cardiac output
man's is higher
VO2max
man's is higher
VEmax
man's is higher
which factor enhance cardiovascular dynamics during exercise such that the exercise can be well tolerated for a significant amount of time
A & C (dynamic breathing efforts and dynamic skeletal muscle activity)
the following is true about the oxidative system and factors that contribute to it
B & C (stroke volume is an important cardiac variable reflecting training responses to aerobic exercise training programs at any level of measurement, a-v o2 difference represents the amount of oxygen extracted and utilized by the working tissues
which of the following factors influence mean partial pressure
directly affected by cardiac output
the ventilatory threshold
A&D (represents a disproportionate increase in minute ventilation as compared to increase in levels of VO2, occurs at a similar exercise intensity to the lactate threshold
which of the following factors contribute to improvements in VO2max
All the above
maximal stroke volume
is reached at approximately 40-60 % vo2max for average trained and untrained individuals alike
which criteria are used to confirm whether or not a person has given a good maximal efforts exercise test
plateauing of vo2 such that there is a difference of 2 ml of vo2 between work stages
minute ventilation during exercise is increase due to the effects of
decrease pH levels in the blood
the following is are true about the exercise induced hyperventilation that occurs during an aerobic session of exercise
it occurs from increase in tidal volume and breathing frequency
which of the following factors typically does not limit a healthy person's ability to exercise at maximal levels of intensity
maximal stroke volume
increase end diastolic volume in the left ventricle results in higher HR response during sub maximal exercise
false
resting cardiac output is regulated by and increased vagal tone and decreased sympathetic tone to the heart
true
exercise cardiac output is regulated by a decrease in vagal tone and an increase in sympathetic tone to the heart
true
this variable is a product of the maximal rate of blood flow and maximal amount of oxygen extraction by tissue
vo2max
