there is a decrease in gym class opportunities, and then there is the traditional model of gym class where it is sports oriented. this is bad because the kids that are out of shape and not good at that sport will continue to sit on the sidelines.
what are some problems with aerobic fitness in children?
limitations in measurement, children may have an acceptable fitness level without doing anything at all. aerobic systems in children are not as trainable in adults. we would need to exercise them at a really high intensity in order to reach a max level. children can have a super high VO2 by doing absolutely nothing.
how do we rank blood pressure in children?
prehypertension= 90th percentile for age and sex. 3.4% of children aged 3-18. hypertension= 95th percentile for age and sex. 3.6% of children 3-18. there is no reason for children to have hypertension.
what is the criteria for overweight and obesity in children?
overweight (at risk for obesity)=85th percentile. obese= 95th percentile . there are no absolute numbers for BMIs for children but just percentiles based on age and sex.
what percent of kids are considered overweight?obese?
16.9% considered obese. 31.8% considered overweight. these numbers have tripled since 1980
what are risks associated with obesity?
elevated total cholesterol, LDL, triglycerides and blood pressure. decreased HDL and fasting insulin.
what is arteriosclerosis?
any hardening (loss of elasticity) of the arteries. it is a more general term.
what is atherosclerosis?
hardening of the arteries due to atheromatous plaque. this is very bad.
what are the skeletal health reccomendations?
weight bearing activities that involve large muscle groups at high intensity loading. “natural” childhood activities.
how can exercise help psychological well being in children?
these issues are not just limited to adults, can help with depression, anxiety, stress, SELF ESTEEM, self concept, hostility,anger, and intellectual function.
what are the pretesting procedures for children?
we need child ASSENT and parental CONSENT. the child has to agree to it too. since they are young they cannot get permission for themselves.
what is chronological age?
how old you actually are- age on the birth certificate age
what field tests do we do for children?
we can do an endurance test (1 mile, 1.5 mile. 2 mile even run or walk with distance completed in a certain time. we an also do a step test or the PACER test (most kids dont know how to pace though). we can also do progressive aerobic cardiac endurance run- real time feedback. children may need extra instructions, support and motivation.
how do we measure body composition in children?
BMI we use % ranking, skin folds (there are different sites though we do not use calf or the biceps), they can also do girth measurements, weighing, BIA, but remember there are differences with adults and kids. we need to be careful not to hurt self esteem such as using the word fat.
how do we test flexibility in children?
trunk flexion-sit and reach test. we can also do trunk extension and shoulder flexibility.
how do you test muscular strength and endurance?
body weight dependent tests are best, if using free weights you really need to watch. dont do one rep maxes. maybe high rep testing is best. but dont want them to get hurt
how do you test anaerobic capacity?
wingate cycle, max jump, sprinting-50 yd run, depends on motor skills?
