Topic 11
Which type of pedagogy is content focused and coach led?
Traditional pedagogy
Phenotype
Characteristics that the individual exhibits
Physical expression of the allele
Function of the inmune system
Protects the body from infectious disease. Involved in tissue repair and protection against potential pathogens.
Functions of the skin
Regulation of body temperature, protection and immunity, sensation, excretion, synthesis of vitamin D
Principal source of energy for brain cells
Glucose and oxygen
What are the three categories of constraints in Newell's model?
Athlete, environmental and task
Potential negative implications of genetic screening
Ethical implications of involuntary exclusion
from, or discrimination in sports or employment.
Possibility of gene doping in the future
Effect of an intense bout of exercise on the inmune system
Increase in leucocytes and inflammation.
Lobes of the cerebrum
Frontal, parietal, occipital, temporal and limbic
Definition of fatigue
A reversible, exercise-induced decline in performance
What are the application of notation in physical education and sporting contexts?
Tactical evaluation, technical evaluation, analysis of movement, development of databases and models, educational use
Genetic factors that may affect performance
Height, muscle fibre type, anaerobic threshold, lung capacity and flexibility
Effect of high and prolonged training loads on the inmune system
Sustained increases in levels of cortisol and adrenaline over long periods suppress the immune system. Leucocyte numbers drop compared to sedentary people.
Main function of cerebellum
Helps smooth and coordinate sequences of skeletal muscle contractions, Regulates posture and balance.
Cause of fatigue in high intensity activities
Depletion of energy sources (creatine
phosphate and ATP) and increase in levels of the products of exercise such as lactate and hydrogen ions.
What are the phases of a phase analysis model of biomechanical analysis for an individual sports technique?
Preparation, retraction, action, follow through
Positive implications of genetic screening in sports
Identification of life-threatening conditions, potential to predict susceptibility to injury and so reduce risk/improve safety
Describe a J curve to explain the relationship between exercise and susceptibility to infection
Moderate amounts of exercise may enhance immune function above sedentary levels, while excessive amounts of prolonged high intensity exercise may impaired immune function.
How are hormone levels regulated?
Use of EPOC for recovery
Restoration of muscle creatine phosphate stores, removal of lactic acid, replenishment of myoglobin stores
Examples of use of digital technology in sports analysis
Hawkeye, Dartfish, Prozone, Bodybyte
Environmental factors that may influence performance
Physical training, nutrition, technological aids and climate
What are lymphocites?
White blood cells which will either destroy pathogens or produce antibodies to mark the pathogens for destruction.
Types of drag
Surface, form and wave
Factors that may influence the amount of drag in sports
Fluid viscosity, surface, size, shape, texture and relative velocity on drag
