Overview

Description

CALENDAR DESCRIPTION:

This course will cover the application of basic mechanics to human movement. It will provide students with a basic understanding of how forces act on body segments and how movements are produced. The subject matter of this course is relevant to quantifying all forms of physical activity, from activities of daily living, physically challenged movement patterns, to elite athletic performance. It also has applications in medical settings, including rehabilitation and sports medicine. Quantitative.

COURSE DETAILS:

BPK 201 applies the principles of Newtonian mechanics to analyze humans movement. The course examines the forces that are generated in muscles and joints to support external loads and produce  movements. The subject matter of the course is relevant to quantifying all forms of physical activity, including activities of daily living, athletic performance, and physically challenged movement patterns. The course will draw on numerous examples relevant to rehabilitation, sports medicine and orthopaedics. This course is designated quantitative. 

BPK 201 is a 13-week course with 3 hours of lecture per week and one 50-minute tutorial per week. The class will meet Mondays and Wednesdays between 3:30 – 4:50 for live Zoom sessions, that include lectures and time for questions and answers. We will work to video record these sessions for later viewing.

DEPARTMENT UNDERGRADUATE NOTES:  It is the responsibility of the student to keep their BPK course outlines if they plan on furthering their education. Missed Exams: Students who miss examinations due to exceptional circumstances (such as serious illness or compassionate reasons) are required to obtain a physician's certificate, whereby the physician states that you were unable to write your midterm or final on the set date due to a medical condition beyond your control, or other supporting documents in order to obtain consideration in the course. Such documents must be filed with the Department Chair (via the Biomedical Physiology and Kinesiology office) or Registrar within four calendar days of the date on which the examination was to have been written. Exceptional circumstances must be approved by the Undergraduate Program Committee in order for a student to receive consideration. Students must check the examination schedule when making course selections. Students are reminded that final examinations may be scheduled at any time during the examination period and that students should avoid making travel or employment arrangements for this period. In the event of a missed midterm or final examination the instructors reserve the right to give an oral examination of the material. Approximate midterm dates are provided, but may be subject to change.   BPK Grading Policy: For more information on the department's grading policy & guidelines go to: http://www.sfu.ca/bpk/undergrad_program/faqs.html
