Concepts And Perspectives Flashcards
1
Q
- Def growth
- Growth as biological activity
- Underlying processes of growth
- Cell growth
A
- Changes in size
- Most dominant biological activity for first 2 decades of life (including prenatal)
- Hyperplasia, hypertrophy, accretion, predom varies with age and tissue
- Process of increasing cell number, size, and layers/networks
2
Q
- Hyperplasia
- Hypertrophic
- Accretion
A
- Increase cell number via mitosis, creating identical cells
- Increase cell size by increasing func units in proteins or substrates
- Increase in intercellular substrate (in/organic) mat binding cells together, like formation of adipose tissue
3
Q
- Maturation
- Timing
- Tempo
- Maturity
A
- Timing and tempo of progress towards mature state in all tissues, varies individually
- When a maturation event occurs
- Rate at which maturation progresses
- State of being mature, vary and can be specific to each biological system
4
Q
- Similarity b/w growth and maturation
- Diff b/w growth and maturation
A
- Are dynamic, unidirectional cellular processes moving towards maturity
- Growth is increase in size (height, body comp, physique) during the process of maturation towards a mature state (complete systems)
5
Q
- Biological dev
- Behavioural dev
- dev motor skills
- Newell’s theory of constraints
A
- Differentiation, specialization, and refinement of stem cells into cell types, tissues, organs, and func units
- Est competence in variety of domains as a person adjusts to their environment through acquisition and refinement of behaviours
- Dev of basic movement patterns depend on the rate of maturation, growth, and maturity status, learning and practice refine motor skills for motor competence
- Movement arises from dynamic interaction of individual constraints with the environment within the task that is being completed
6
Q
- Physical activity
- Importance in childhood
- Attitudes towards physical activities
A
- Any type of increase in muscle expenditure over resting E, including free play, exercise, chores, manual labour etc
- Healthy weight regulation and health
- Habits and attitudes towards physical activity can be carried over to adulthood and influence lifestyle decisions in health
7
Q
- Training for sport
- Physical fitness
A
- Highly specialized systemic practice for a discipline for a particular season
- An adaptive state which changes with growth and maturity with diff comp (strength, aerobic, etc) or planned and structured physical activity with the objective of achieving a goal or maintaining state of physical fitness
8
Q
Physical performance in children
A
Learn, dev and refinement of motor skills, first 7-8 years dev basic movement before specialization
9
Q
- Isometric growth
- Allometric growth
- Relative v. absolute size change
A
- Body parts grow at the same rate and relative size and external features stay constant
- Body parts grow at diff rate, change in size and external features
- Absolute size change is value of size change (cm, kg), relative is change comp to other body parts
10
Q
- Scammon’s growth curve
- Four phases of growth
- How GMD interact
A
- Growth curves for diff body sys gen by toddies and organ weight at each age
- Rapid gain infancy to early childhood, steady mid childhood, rapid gain adolescence, slow increase until adult stature
- GMD work together to influence self-concept, self-esteem, and perceived competence
11
Q
- Chronological age v. biological processes
- Adjusted age
- Use of chronological age and research
A
1.Chronological age is a reference point using time for GMD but individuals reach diff states of biological maturity at different ages
2. Children with premature birth are developmentally behind their peers for early infancy, using agdjust
3. Def age for research allows for comparisons b/w studies
12
Q
- Sig of age groups
- Reasons to study GMD
A
- determine normal bio vari and compare childs GMD change over time (participant vari), b/w children with diff age/gender (b/w participant), variables differ b/w pop (b/w pop vari)
- Evaluate status and progress, predict, track, gen ref
13
Q
- Pros of early training
- Cons of early training
- Peak yrs in sport
A
- reg phys activity, stronger CVH, increase phys fitness, social skills
- fall behind in other skills, MSK injuries, stress of competition
- depends on sport type (endurance, strength, etc)
14
Q
- Age groups in infancy
- Age groups in childhood
- Adolescence
A
- first year, perinatal (1 week), neonatal (1 month), postnatal (rest of yr 1)
- early childhood (1-4), middle childhood (4-10)
- WHO says 10-18 but vari in onset
