COURSE-LEVEL EDUCATIONAL GOALS:

  1. Define, distinguish, and estimate energy, work, power, and efficiency as they apply to exercise and physically demanding tasks.
  2. Predict motor unit/muscle fibre recruitment and rate coding exhibited during different muscle contraction types and exercise modalities, and the effects of modulatory factors such as fatigue.
  3. Describe the biochemical processes that consume energy and those that supply energy, and the control processes that ensure they are matched.
    a. Apply bioenergetic principles (thermodynamics and kinetics) to explain and calculate cellular energy transduction during exercise.
    b. Describe how cellular-level energy consumption integrates to whole-body energy expenditure.
  4. Predict the cardiovascular, ventilatory, and neuroendocrine adjustments to defend homeostasis in response to different exercise and environmental factors, in particular the mobilization and transport of oxygen, substrates, and metabolites at the whole-body level.
  5. Describe the negative effects of exercise, including fatigue, muscle damage, and dehydration, and the time courses of their post-exercise recoveries.
  6. Evaluate the risks of adverse events during exercise and propose mitigation strategies.
  7. Describe the mechanisms of training-induced adaptations at the cellular and systems levels:
    a. Cellular: explain in detail the basis of cellular plasticity as it applies to skeletal muscle and apply the concepts to other cell types.
    b. Systems: explain in detail the cardiac, vascular, respiratory, and metabolic adaptations to training and acclimation to environmental stressors.
    c. Describe the neural adaptations to endurance, strength, and power training.
    d. Describe the effects and mechanisms of detraining and deconditioning.
  8. Predict how exogenous factors (e.g., environmental factors, age & sex) modify exercise load, acute responses, and tolerance, as well as adaptations to chronic exposure.
    a. Evaluate acclimation strategies.
  9. Assess the physiological demands of an occupational, recreational, or sport task and develop a valid pre-screening or job placement assessment protocol.
  10. Interpret physiological data collected during exercise for prescribing training, assessing physiological function, diagnosing disease, or determining performance limiters.
    a. Select appropriate technologies to assess energy expenditure, cardiac strain, strength & power requirements, and tolerance to environmental factors.
  11. Apply concepts of clinical exercise physiology to research the roles of exercise in diagnosing and treating chronic diseases.

Department Undergraduate Notes:

It is the responsibility of the student to keep their BPK course outlines if they plan on furthering their education.

Registrar Notes:

ACADEMIC INTEGRITY: YOUR WORK, YOUR SUCCESS

SFU’s Academic Integrity web site http://www.sfu.ca/students/academicintegrity.html is filled with information on what is meant by academic dishonesty, where you can find resources to help with your studies and the consequences of cheating.  Check out the site for more information and videos that help explain the issues in plain English.

Each student is responsible for his or her conduct as it affects the University community.  Academic dishonesty, in whatever form, is ultimately destructive of the values of the University. Furthermore, it is unfair and discouraging to the majority of students who pursue their studies honestly. Scholarly integrity is required of all members of the University. http://www.sfu.ca/policies/gazette/student/s10-01.html
