The ability to resist movement
What is stability?
1) Objects in motion stay in motion until acted upon by a force;
2) F = m*a; a = F/m;
3) For every action there is an equal and opposite reaction
What are Newton's First, Second, and Third Laws?
Type I, Type IIa, Type IIb
What are the three muscle fibre types?
Genetics are primarily responsible for motor development.
What is the maturational perspective? (you'll need to know Information Processing and Ecological)
Relate to an individual’s body structure
What is an individual structural constraint?
Process of laying down new bone material
What is ossification?
All movements directed toward from the intended target
What movements are involved in the execution phase?
An increase in the number of cells
What is Hyperplasia?
These cells never disappear
Adipose cells (review body systems including the definitions of each one)
Beliefs, thoughts, or expectations that are internally or externally placed on and individual.
What are environmental sociocultural constraints?
An involuntary movement with an external stimulus followed by a response
What is an infantile reflex? (Review the types of reflexes too)
Period of time where child is sensitive to external stimuli
What is a Critical period?
At what age does peak height velocity occur for females and for males?
12; 14
Within the endocrine system, this hormone leads to losses in bone and muscle tissue for older adults
What can Gonadal hormones impact?
Relate to an individual’s behaviour and can change over a short period of time
What are individual functional constraints?
Factors that can restrict or slow the emergence of a motor skill
What are rate limiters? (Review rate limiters for infants' locomotor movements)
A continuous age-related process of change in movement
What is motor development?
Mature hopping develops by age?
5
Zygote, blastomere, blastocyst
What is the order for prenatal development?
Characteristics of the surroundings/environmental
What are environmental physical constraints?
Qualitative advances in cells, organs, or body systems
How is Maturation defined? (review this slide which has Growth and Aging definitions too)
Remove old bone material
What is the role of osteoclasts?
What is a healthy body fat percentage for a 21-year-old female?
15-20%
Growth from core to extremities
What is Proximodistal growth? (Review cephalocaudal growth too)
The rules, goals, and equipment related to movement.
What are task constraints?
