what are the 6 components of health-related fitness
cardiovascular endurance, muscular strength, muscular endurance, flexibility, body composition, skeletal strength
6 components of skill-related fitness
coordination, balance, agility, speed, power, reaction time
PROVIDE SEVERAL HEALTH-RELATED STATISTICS
SUPPORTING THE NEED FOR DAILY VIGOROUS
PHYSICAL ACTIVITY IN ELEMENTARY SCHOOLS
According to the Surgeon General’s report, the number of overweight
children has doubled and the number of overweight adolescents has tripled since 1980; the CDC warns that one in three children born is 2000 will become diabetic
unless they start exercising more and eating less; The CDC warns that we may be seeing the first generation of children who will not
outlive their parents
DESCRIBE FACTORS ASSOCIATED WITH THE
PSYCHOLOGICAL BENEFITS OF REGULAR PHYSICAL
EXERCISE
Reduces feelings of depression and anxiety and promotes psychological well-being; Children who are more fit generally have greater self-confidence and self-
esteem; Participation in rigorous physical activity reduces stress; Participation in regular physical activity is associated with improvements in
sleep patterns.
PROVIDE A STATEMENT IN SUPPORT OF THE NEED
FOR SKILL-RELATED FITNESS DEVELOPMENT WITHIN
THE ELEMENTARY SCHOOL CURRICULUM
Windows of opportunity – critical
periods; Children who possess the basic motor skills develop confidence and are
more likely to seek out
opportunities
PROVIDE SEVERAL PSYCHOLOGICAL FACTORS
ASSOCIATED WITH THE DEVELOPMENT OF
PROFICIENT MOTOR SKILLS DURING CHILDHOOD
Children with confidence in motor skills are more likely to seek out
physical challenges.
Proficiency in fundamental movement skills increases the likelihood
of success in novel endeavors.
Development of fundamental motor skills and confidence in abilities in
the psychomotor domain will increase the likelihood of an active
lifestyle, perhaps into the adult years.
explain what is meant by “windows of opportunity” for optimizing neural circuitry
at birth humans have the most “potential” to learn because not all neural wiring has been completed
explain how heredity and environmental influences can
affect the physical and cognitive development of children
Children inherit a timetable regarding rates of
physical growth, as well as neural maturation.
Beginning with prenatal development, the environment interacts with inherited factors to
shape the physical and cognitive development of children. In essence, early experiences can
actually affect the neural structure of a developing organism.
nature-nurture relationship
How does the development of myelin affect motor skill acquisition?
myelinated axons result in faster transmission times and increase in neuronal fire power with less fatigue. myelination is crucial to the acquisition of motor skills and myelin development can affect the availability to track moving objects and catch a ball
define: CNS, PNS, Afferent Neurons, Efferent Neurons, Soma, Dendrites, Axon
CNS: central nervous system; responsible for making decisions based on sensory information
from the body’s environment. PNS: peripheral nervous system; neural network between organs,
muscles and glands. Afferent neurons: info from PNS delivered to CNS. Efferent neurons: info
from CNS to muscles and glands. Soma: cell body of a neuron. Dendrite: nerve fibers that send
and receive messages. Axon: carries signals away from soma to other cells.
Describe what is meant by “activated motor units.”
When the neuron fires, all of the muscle fibers associated with that neuron will contract
What is a Neuromuscular Unit?
A motoneuron and all of the muscle fibers it innervates
Why is exercise during the pediatric and
adolescent years so important for bone
development?
There appears to be critical periods in developing strong bones, to the extent that adults after about 30 years of age have a much more difficult time building strong dense
bones.
Differentiate the development of fat mass in children
versus adults, in terms of hypertrophy and hyperplasia
of cells
Children gain body fat through an increase in the size of the fat cells (hypertrophy) as well as
an increase in the number of fat cells (hyperplasia).
After adolescence however, fat mass is gained almost exclusively by increasing the size of the
cells that were accumulated during childhood
Define Edomorphic, Ectomorphic, and Mesomorphic
Endomorph-round or pudgy, pear shaped in appearance
Ectomorph- thin, lanky
Mesomorph- muscular
Children with which somatotype(s) are generally at
advantageous or disadvantage for acquiring motor skills?
children with a mesomorphic
somatotype have been shown to be at an advantage for physical activity and skill acquisition. Mesomorphic elementary-aged children appear to have an advantage even in
activities requiring long-distance running.
For the most part, children with an endomorphic somatotype are at a disadvantage for physical
activity, and for acquiring new motor skills. The additional adipose tissue makes fitness activities
as well as skilled physical movement more difficult and thus demotivating
Define: Aerobic Power; Stroke Volume, Basal
Metabolic Rate; Cephalocaudal Progression; Proximodistal
Progression, Gross to Fine Progression
Aerobic Power - Basically this refers to how well the body can take in and utilize oxygen.
Stroke Volume - The amount of blood pushed through the heart per stroke. Children have a lower stroke volume than adults, primarily because they have a smaller heart muscle. This results in a higher heart rate than adults.
Basal Metabolic Rate – A child’s metabolism is much faster than an adult. Children will naturally have higher heart rates, burn calories faster, and need to eat more often than adults
Cephalocaudal – Growth proceeds
longitudinally from the head to the feet
Proximodistal – Growth proceeds from the center of the body toward the periphery.
Gross to Fine – Skill acquisition generally takes place on a developmental continuum from the acquisition of gross motor skills to more fine motor control. This continuum is related to the maturation of the nervous system as well as physical practice.
Motor Control
A long-term change in the performance of motor skills as a
result of the maturation of the underlying biological systems involved in movement
Motor Learning
A long-term change in the performance of a motor skill
resulting from practice and/or experience
Motor Development
Changes in motor skill ability as a result of the biological, and behavioral, changes associated with a developing organism
Growth
A change in size or quantity
Maturation
Qualitative changes in motor performance dependent upon a
genetic timetable for motor control as well as experience and practice
Readiness
Level of maturation that prepares an individual to acquire a
skill or understanding. Very skill and/or concept dependent.
Adaptation
The process of altering physiology and/or behavior in order to
optimize survival in a changing environment
