Child is what age range?
Up to 11 years old
What is the age range for adolescent?
What system in regards to the growth pattern for the youth, develops the earliest?
Neural system over 90% developed by age 6
What is peak height velocity and what is average age?
Age when max velocity in stature occurs
Girls - 12
Boys - 14
Resting HR is _______ in kids.
> 100 at birth, 75 bpm in adolescence
Is resting SV lower or higher in kids?
Why is SV lower in kids?
The increase in ventricular volume
Is resting cardiac output lower or higher in kids vs adults?
Does BP trend higher or lower for kids?
Submax HR is _______ in kids.
Submax SV is _______ in kids.
Submax cardiac output is ________ in kids.
A-VO2 difference is _____ in kids
Submax BP is _______ in kids.
Do kids recover slower or faster from exericse?
faster! Less lactate production and less catecholamines release and less rectruiemtnbe of type II fibers
Max HR is ______ in kids.
Max SV is _____ in kids.
Max Q is _____ in kids.
Resting breathing frequency is ______ in kids.
Higher (Same at submax and max exericse)
Kids have smaller lungs so they breathe more often a dn get less air per breath
Resting tidal volume and minute ventilation is _____ in kids.
Lower (same at submax/max)
Do kids reach steady state slower or faster?
Oxygen deficit is _____ in kids vs adults.
T/F kids reach steady state exericse faster, develope smaller oxygen deficit and recover faster.
HR intensities are _____ for kids at any % max.
Resting metabolic rate is ______ in kids.
Do kids have a lower or higher proportion of type 1 fibers?
Do kinds utilize fat higher or lower in kids?
Higher! So a lower CHO utilization
There is a _____ lactate production in kids.
Lactate threshold is _____ in kids.
Musuclar ATP is ______ in kids.
Phosphocreatine stores are ______ in kids. Q
In regards to muscular adaptations, is it similar to kids compared to adults?
Yes! Inc in glycogen stores, inc PFK activity and inc in phosphocreatine stores
What may kids perceive exercise easier?
Because of lower lactate production at a given intensity
Are kids more or less efficient in regards to energy use to get something done?
Less efficient - this improves with age. So they need more energy for a given amount of work
*same with VO2/kg - less economical
Kids have a _____ resting energy expenditure.
Kids have a _____ stride length and _____ stride frequency.
Kids have a ______ co-contraction of antagonistic muscles.
Absolute VO2max is ______ in kids.
What does it mean in regards to "trigger hypothesis"?
Hormonal changes associated with puberty are needed in order to see training related changes in VO2max
Testosterone and estradiol levels are _____ in kids.
Growth hormone and IGF-1 levels _______ as children are towards adolescence, then they _______.
*assocaited with peak heigh velocity
GH and IGF-1 levels are ____ in obese subjects compared to non-obese subjects.
Glucose levels _____ mid-puberty in both boys and girls.
At mid-puberty, insulin levels in girls are _______ than in boys.
Girls *greater insulin requirement to process glucose in girls compared to boys
In regards to adrenal hormone responses, kids have a _____ catecholamine response during exercise.
Cortisol levers are ______ in obese subjects compared to non-obese subjects.
Children produce _____ heat and heat up ______ compared to adults.
Metabolic year production is ______ in children and core temp rises faster.
Children sweat _____ and have _____ fluid reserves compared to adults.
Do children have more or less sweat glands?
Less! Which leads to lower plasma and blood volumes
Do children divert less or more blood to the skin compared to adults?
More! Because they can't seat as effectively as adults
When should fluids be "forced" to help prevent heat stress in youths?>
At 20 minute intervals
If a child has 30 minutes of exercise, they should spend _____ minutes out of the sun.
What is the physical activity recommendations for the youth?
At least 60 minutes a day of moderate-vigorous
*bone loading of 3 days a week
How to children respond to resistance training?
Same as adults - inc lean mass, inc strength, inc bone mineral density
Kids have a larger or smaller surface area compared to their mass?
Are kids less or more prone to cardiovascular drift?
More! Because they are diverting more blood to the skin in order to cool the body, leaving less blood in central circulation
